How do gate valves perform in high-temperature environments?

Performance of gate valves in high temperature environments. As a common device for cutting off fluid flow, gate valves are widely used in various industrial piping systems. However, in high temperature environments, the performance of gate valves will be greatly affected. Let me talk about the performance of gate valves in high temperature environments, analyze possible problems, and propose corresponding solutions.

1. Basic structure and working principle of gate valve

Gate valve is composed of valve body, gate plate, valve stem, sealing ring and other components. Its working principle is to rotate the valve stem to make the gate move up and down in the valve body to cut off or circulate the fluid. Due to its simple structure, good sealing performance and low fluid resistance, gate valves are widely used in many industrial fields, ball valve factory.

2. Effect of high temperature environment on gate valve performance

In high temperature environments, the performance of gate valves will be greatly affected. Specifically manifested in the following aspects:
a. Decreased sealing performance: High temperature will cause aging and deformation of the sealing ring, resulting in reduced sealing performance and leakage.
b. Valve body deformation: High temperature will cause the valve body material to expand, causing the valve body to deform, affecting the movement of the gate, or even getting stuck.
c. Gate stuck: High temperature will reduce the gap between the gate and the valve body and increase the friction, causing the gate to get stuck and unable to open or close normally, wholesale gate valve.
d. Valve stem bending: High temperatures will soften the valve stem material and make it susceptible to bending due to external forces, affecting the movement of the gate.
e. Changes in fluid properties: High temperature will cause changes in fluid properties, such as reduced viscosity, increased corrosiveness, etc., which puts higher requirements on the sealing performance and material performance of the gate valve.

3. Selection and maintenance of gate valves in high temperature environments

In view of the problems that may occur with gate valves in high temperature environments, we can select and maintain them from the following aspects.
1. Use high-temperature-resistant materials: For example, use high-temperature-resistant materials such as ceramics and cermets to make gate plates and sealing rings to improve their high-temperature resistance.
2. Optimize structural design: Reduce the impact of high temperature on gate valve performance by optimizing structural design, such as adding heat dissipation devices, improving lubrication conditions, etc.
3. Strengthen maintenance: Regularly inspect and maintain the gate valve, such as replacing sealing rings, cleaning the lubrication system, etc., to ensure that it is in good working condition.
4. Improve the manufacturing process: By improving the manufacturing process level, such as using precision processing, heat treatment and other technical means, the high temperature resistance and service life of the gate valve can be improved.
5. Choose products from professional manufacturers: Choose high-temperature gate valve products produced by professional manufacturers to ensure that their quality and performance meet national standards and industry requirements, carbon steel gate valves.
