Introduction to Ten Maintenance Measures for High Temperature and High Pressure Check Valves

How to maintain high temperature and high pressure valves, top ten measures: 1. Lubricate with grease. Lubricating grease should be compatible with high-temperature and high-pressure valve metal materials, rubber parts, plastic parts, and working media. When the working medium is gas, special 221 lubricating grease can be used, for example. In the installation groove of the seal

Several commonly used valves in chemical production and their applications and functions

The four types of valves introduced here are the most commonly used shut-off valves in the chemical industry. Their main function is to connect and cut off the flow of medium in the pipeline. Although some of them can adjust the flow rate, they cannot be used entirely as regulating valves. 1、 Ball valve This is a very comprehensive valve

What situations may cause check valves to malfunction?

The malfunction of check valves may be caused by various factors, including improper selection, installation errors, medium problems, component damage, and improper maintenance. The following is a specific explanation of the situation: Improper selection Pressure parameter mismatch: If the nominal pressure of the check valve is less than the working pressure of the pipeline system, the valve may be damaged due to inability to withstand pressure and cannot check normally. On the contrary, if the nominal pressure is much higher than the actual working pressure
