The advantages of ceramic valves are that metal valves are limited by the conditions of the metal material itself, making it difficult to meet the needs of harsh working conditions such as high wear and strong corrosion. Mainly manifested as short service life and severe leakage, greatly affecting the stability of system operation. Traditional metal valves urgently need to be thoroughly innovated in terms of materials, design, and manufacturing processes. Wear resistant ceramic valves made of special ceramic materials are mainly used in industrial fields such as power, petroleum, chemical, metallurgy, mining, and sewage treatment. Especially in the face of harsh working conditions such as high wear, strong corrosion, high temperature, and high pressure, their excellent performance is demonstrated. It can meet the high wear and strong corrosion usage environment, and its outstanding feature is the ultra long service life. Its cost-effectiveness is far superior to other similar metal valves, and ceramic valves are increasingly recognized by industry insiders for their excellent performance.

Advantages of ceramic valves:
① The sealing and vulnerable components of the valve are made of high-tech new ceramic structural materials to extend its service life, which improves the wear resistance, corrosion resistance, and sealing performance of the valve product, greatly extending its service life.
② The use of ceramic valves can greatly reduce the maintenance and replacement frequency of valves, improve the safety and stability of supporting equipment operation systems, reduce the labor intensity of workers, and save equipment repair costs.
③ The promotion of the use of ceramic valves for environmental protection has improved the sealing performance of industrial pipelines, while minimizing leakage and playing a positive role in promoting environmental protection.
④ Low raw material cost: The raw materials for manufacturing ceramics are widely available and cost-effective. Ordinary elements such as aluminum, carbon, and silicon can be used to produce high-performance ceramic materials, which can save a large amount of metal materials and rare mineral resources.

Ceramic ball valve：
Ball valves can be used for flow control of corrosive or high-temperature fluids containing solid substances. Depending on the application, all flow components can be made of ceramic, or only important parts can be sprayed with ceramic. If the channel of the ball valve changes from a circular hole to a triangular hole, the flow characteristics are roughly equal in percentage. Therefore, when the valve positioner is installed, it can be used as a regulating valve. If the vertex of a triangular hole is made into an angle shape, the range of amplitude variation will be large, making it ideal as a regulating valve. However, if the corner is not a fillet, it will cause stress concentration and easy to crack. Therefore, although the adjustment performance of the regulating valve will be slightly reduced after the fillet is made, it should be made into a fillet shape. At this point, the fluid flow rate through the regulating valve also increases, which exacerbates corrosion and wear. Therefore, it is more important to utilize and utilize the characteristics of ceramics.

Ceramic gate valve：
It is necessary to use this type of valve under extremely harsh conditions in coal gasification equipment, where the high temperature and high pressure gas contains hard particle corrosive gas streams of coal powder and ash powder. In the past, valves made of metal with cobalt chromium tungsten hard alloy deposited on the sealing surface could not meet the requirements for use. Nowadays, metal is used for the high-temperature and pressure resistant parts of the shell, while ceramic is used for the sealing parts. Due to the development of a unique structure to prevent micro powder abrasion, the service life of the valve has been greatly improved.

Ceramic diaphragm valve：
The structure of the diaphragm valve is very simple, and its contact medium part is composed of a ceramic valve body and a PTFE diaphragm. After precision grinding and polishing treatment, the ceramic valve seat surface is completely pressed against the diaphragm without leakage. As a supporting rubber lining material, fluororubber is used. The channel of the ceramic valve body has a smooth surface and minimal friction with the medium.

According to their structural form, cast iron gate valves can be divided into rising stem gate valves and hidden stem gate valves. Further research is needed on the specific structural characteristics and application scenarios.

The opening and closing component of a gate valve is the gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape. The wedge angle varies with the valve parameters, usually 50 degrees, and 2 ° 52 'when the medium temperature is not high.

The gate of a wedge gate valve can be made as a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.

When the gate valve is closed, the sealing surface can be sealed solely by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing surface is sealed, which is called self sealing.

Most gate valves use forced sealing, which means that when the valve is closed, external force must be used to forcefully press the gate plate against the valve seat to ensure the sealing performance of the sealing surface.
The gate of a gate valve that moves in a straight line with the valve stem is called a rising stem gate valve (also known as a lift stem gate valve). Usually, there are trapezoidal threads on the lifting rod, which convert rotational motion into linear motion through the nut at the top of the valve and the guide groove on the valve body, that is, convert operating torque into operating thrust.

Some valves have valve stem nuts installed on the gate plate, and the handwheel rotates to drive the valve stem to rotate, thereby lifting the gate plate. This type of valve is called a rotary stem gate valve or a concealed stem gate valve.

The degree of leakage at the packing of the electric gate valve can be determined by the following methods:

1、 Direct observation method

Visual observation: During the operation of the electric gate valve, directly observe whether there is any medium leakage at the packing point. If you can see obvious liquid or gas seeping, dripping, or spraying from the packing, it indicates that there is a leak. The degree of leakage can be roughly judged based on the size and speed of the leakage, such as a small amount of dripping, linear leakage, jet leakage, etc. The leakage amount increases in turn, and the degree of leakage also increases in turn.

Auditory judgment: Sometimes leaked media may produce sound, such as hissing sound when gas leaks, ticking sound or water flow sound when liquid leaks, etc. Hearing can assist in determining whether there is a leak and the approximate extent of the leak. Generally, the louder the sound, the more severe the leak.

2、 Collect measurements

Statutory quantity collection: For situations where a brief shutdown is allowed, a collection container can be placed below the filling area to collect the leaked medium for a certain period of time, and then the volume or weight of the collected medium can be measured to accurately determine the degree of leakage. For example, if 10 milliliters of liquid leakage is collected within 1 hour, the severity of the leakage can be evaluated based on this data.

Test paper detection: When the leaked medium has certain chemical properties, corresponding test papers can be used for detection. For example, for acidic or alkaline media, the test paper can be placed near the filler. If the test paper changes color, it indicates a leak, and the size of the leak can be roughly judged based on the degree of color change of the test paper.

3、 Pressure detection method
Import and export pressure difference monitoring: Install pressure sensors at the inlet and outlet of the electric gate valve to monitor the pressure difference in real time. Under normal circumstances, the pressure difference between the inlet and outlet should remain stable within a certain range when the valve is closed. If there is a leakage at the packing point, the pressure difference between the inlet and outlet will gradually decrease, and the degree of leakage can be determined by observing the changes in pressure difference. The more and faster the pressure difference decreases, the more severe the leakage.

Packing box pressure monitoring: Install pressure sensors at the packing box to directly measure the pressure inside the packing box. When there is a leakage at the packing point, the pressure inside the packing box will change, and the leakage situation can be determined by monitoring the pressure change. For example, as the leakage increases, the pressure inside the stuffing box will gradually decrease.

4、 Temperature detection method
Infrared thermal imaging detection: Use an infrared thermal imaging device to detect the electric gate valve and observe the temperature distribution at the packing point. If there is a leak at the packing site, the leaked medium will carry away heat, resulting in a temperature difference between the packing site and the surrounding environment, which will be displayed in different colored areas on the thermal imaging map. By analyzing the size of the temperature anomaly area and the degree of temperature change at the filling point in the thermal imaging image, the degree of leakage can be determined.

Contact temperature measurement: Use a contact thermometer to measure the temperature at the packing and compare it with the temperature during normal operation. If the temperature significantly decreases or increases, and other factors are excluded, it may be due to leakage. For example, when cold water leaks, the temperature at the packing will decrease; When hot air leaks, the temperature at the packing will increase.

5、 Flow monitoring method
Comparison of total flow rate: Install a flow meter to measure the total flow rate of the system throughout the entire process. When the filling of the electric gate valve leaks, the total flow rate of the system will be greater than the flow rate during normal operation. By comparing the actual flow rate with the theoretical normal flow rate, the degree of leakage can be roughly determined. The larger the difference, the more severe the leakage.

Local flow monitoring: Install flow meters near the inlet and outlet of electric gate valves or packing boxes to specifically monitor the flow rate of the medium leaking through the packing. This method can more accurately measure the leakage flow rate, thereby accurately determining the degree of leakage.

The sealing performance of ball valves is affected by various factors, and the following are some of the main factors:

1、 Sealing auxiliary material

Hard sealed ball valves adopt a sealing structure between metals, usually using a spring pressed tight cover or mechanical sealing between metals; Soft sealed ball valves use elastic materials for sealing, usually rubber, PTFE and other materials. Hard sealed ball valves have good sealing performance, can withstand media under high temperature and high pressure conditions, and have high corrosion resistance;

The sealing performance of soft sealed ball valves is generally poor and suitable for low temperature, low pressure or general working conditions. Due to the good sealing performance of hard sealed ball valves, the hard double sealing structure is suitable for special working conditions such as high temperature, high pressure, and corrosive media, such as industries such as petroleum and chemical; Soft sealed ball valves are suitable for general working conditions, such as pipeline systems for tap water, natural gas, etc

2、 Processing accuracy
Dimensional accuracy: The dimensional accuracy of key components such as the ball and seat of a ball valve directly affects its sealing performance. If the roundness of the ball is not sufficient, the diameter deviation is too large, or the inner diameter of the valve seat is inaccurate, the ball and valve seat may not be able to fit tightly when the ball valve is closed, resulting in leakage.

Surface roughness: The surface roughness of the sealing surface also has a significant impact on the sealing performance. Overly rough surfaces can lead to poor sealing, while excessively smooth surfaces may affect the micro meshing effect between sealing materials. Generally speaking, the surface roughness of the sealing surface should be controlled within an appropriate range to ensure good sealing effect.

3、 Assembly quality
Component installation sequence: If the assembly sequence of the ball valve is incorrect, it may lead to uneven stress and deformation of the components, which in turn can affect the sealing performance. For example, when installing the valve seat, if it is not installed in the prescribed order and method, it may cause the valve seat to be installed improperly or deformed, resulting in poor sealing between the ball and the valve seat.

Pre tightening force control: During the assembly process, the pre tightening force applied to the sealing pair should be moderate. The pre tightening force is too small to ensure a tight fit between the sealing surfaces, which can easily lead to leakage; Excessive pre tightening force may cause excessive wear, deformation, or even damage to the sealing surface, shorten the service life of the ball valve, and affect the sealing performance.

4、 Medium characteristics
Corrosivity: If the medium is corrosive, it will cause corrosion on the sealing surface of the ball valve, resulting in defects such as potholes and pitting, which will damage the flatness and smoothness of the sealing surface, leading to seal failure. For example, in chemical production, media containing strong acids and bases can quickly corrode ordinary metal sealing surfaces.

Temperature and pressure: Changes in the temperature and pressure of the medium can have a significant impact on the sealing performance of ball valves. In high temperature environments, the performance of sealing materials may change, such as a decrease in hardness, a decrease in elastic modulus, etc., resulting in a decrease in sealing force; In high-pressure environments, the sealing pressure between the sphere and the valve seat increases. If the sealing material has insufficient compressive strength, it may be crushed and cause leakage.

5、 Operating conditions
Opening and closing frequency: Frequent opening and closing operations will cause the sealing pair of the ball valve to constantly rub and wear. As the number of uses increases, the wear of the sealing surface will gradually intensify, leading to a decrease in sealing performance. For example, in some automated production lines, ball valves need to be frequently opened and closed to control the transportation of materials, which can greatly affect the sealing performance of the ball valves.

Operation speed: The opening and closing speed of the ball valve may also affect the sealing performance if it is too fast or too slow. Excessive opening and closing speed may result in water hammer, causing impact damage to the sealing surface; If the opening and closing speed is too slow, it may cause the sealing surface to remain in a semi open and semi closed state for a long time during the opening and closing process, which is susceptible to erosion and wear by the medium.

6、 Maintenance and upkeep
Regular inspection: Regularly inspect the ball valve to promptly detect issues such as wear and corrosion on the sealing surface, and take corresponding measures for repair or replacement, which can effectively extend the sealing life of the ball valve. If not checked for a long time, the sealing problem may gradually deteriorate, ultimately leading to serious leakage.

Cleaning and lubrication: Keep the interior and sealing surfaces of the ball valve clean, prevent impurities, particles, etc. from entering between the sealing surfaces, and avoid scratching and wear on the sealing surfaces. At the same time, regularly lubricating the valve stem, bearings, and other parts of the ball valve can reduce friction during operation and help maintain good sealing performance of the ball valve.

Classified by structural form: thin film regulating valve, spring thin film regulating valve, piston regulating valve, lever regulating valve, and bellows regulating valve.

To prevent leakage faults inside the pressure reducing valve, measures need to be taken from multiple aspects such as correct installation, daily maintenance, and operation management of the equipment. The following are specific methods:

1、 Correct installation and selection
Reasonable selection: Based on actual working conditions such as working pressure, temperature, medium and other parameters, select appropriate specifications and types of pressure reducing valves to ensure that their rated pressure, flow rate and other indicators meet system requirements, and avoid leakage caused by long-term overload or unsuitable working conditions of pressure reducing valves due to improper selection.

Installation specifications: Strictly follow the installation instructions to install the pressure reducing valve, ensuring that the installation position is correct, the inlet and outlet pipelines are firmly connected and stress free. During installation, attention should be paid to avoiding additional stress on the pressure reducing valve caused by installation errors in the pipeline, and to prevent the valve core and seat from being poorly sealed due to uneven stress.


2、 Media management
Medium cleaning: Install an effective filtering device in front of the pressure reducing valve to filter out impurities, particles, etc. in the medium, preventing them from entering the interior of the pressure reducing valve, scratching the sealing surface of the valve core and seat, and causing leakage. Regularly clean or replace the filter element to ensure the filtering effect.

Control of medium characteristics: For corrosive media, appropriate pressure reducing valve materials or corresponding anti-corrosion measures should be selected based on their corrosiveness, such as using corrosion-resistant valve core and seat materials or applying anti-corrosion coatings to pressure reducing valves. At the same time, it is necessary to control the temperature, humidity, and other parameters of the medium to avoid adverse effects on the sealing performance of the pressure reducing valve due to changes in the characteristics of the medium.

3、 Daily maintenance
Regular inspection: Establish a comprehensive equipment inspection system, conduct regular visual inspections of pressure reducing valves to check for signs of leakage, loose connections, and deformation of valve bodies. At the same time, check the wear of the sealing surface between the valve core and valve seat. If severe wear is found, repair or replace it in a timely manner.

Seal maintenance: Regularly replace the seals of the pressure reducing valve, such as O-rings, packing, etc., usually every 1 to 2 years depending on the material and usage environment of the seals. When replacing seals, it is important to ensure that the selected seals meet the required quality standards, are installed correctly, and avoid leaks caused by aging or damage to the seals.

4、 Operation management
Pressure stability control: Maintain system pressure stability and avoid excessive pressure fluctuations that may impact the pressure reducing valve. By installing suitable stabilizing devices such as accumulators and pressure regulating valves, the system pressure can be regulated and buffered, reducing the frequency of opening and closing the pressure reducing valve, lowering the wear of the valve core and seat, and preventing leakage.

Operating standards: Operators must strictly follow the operating procedures to operate and maintain the equipment. When starting and stopping the equipment, they should proceed slowly to avoid adverse effects on the pressure reducing valve due to sudden pressure changes. At the same time, unnecessary adjustments and operations should be avoided during the operation of the pressure reducing valve to prevent leakage caused by misoperation.
