Safety valve maintenance and care

When the safety valve is in operation, if conditions permit, the distance between the opening pressure and the working pressure should be increased as much as possible to prevent the safety valve from opening frequently, which may affect the service life of the valve.
2. Safety valves should be opened as little as possible and must not be used as warning signals.
3. Safety valves are the main accessories of pressure vessels and should be numbered and filed by designated personnel for management.
4. Regularly check whether the safety valves in operation have any abnormal phenomena such as leakage, jamming or rust on the springs.
5. The safety valve should be removed regularly for thorough cleaning, inspection and calibration before being reused.
6. Safety valves installed outdoors should take appropriate protective measures to prevent rain, fog, dust, rust and other contaminants from entering the safety valve and the discharge pipe. When the ambient temperature is below zero degrees Celsius, necessary anti-freezing measures should be taken to ensure the reliability of the safety valve's operation.
