what is a safety valve?---Safety Valve Definition
The safety valve is a valve that plays a role of fail-safe protection. An example of a safety valve is a pressure release valve, which automatically releases substances in a boiler, pressure vessel, or other system when the pressure or temperature exceeds a preset limit. The pilot operated safety valve is a special type of pressure safety valve. A leak-proof, lower cost, single emergency use option is the rupture disk.
How does the safety valve work?
The safety valve is used to prevent the pressure increase from causing malfunction, fire or explosion. The safety valve has only mechanical parts, so it is used when the electronic or pneumatic safety device fails. The safety valve is completely driven by the medium of the system and keeps working in the event of a power failure.
Safety valves play an important role in ensuring the safety of personnel and equipment. Building on the long-term legacy of comprehensive safety valves, we work closely with customers and regulatory agencies to configure, design and manufacture safety valves to help maintain safer operating conditions in various environments.
How many types of safety valves are there?
There are mainly two types of safety valves. Spring type safety valve and pilot type safety valve.
Spring safety valve
The spring force Fs is transmitted to the plate that closes the nozzle through the main shaft, and the plate is closed together to ensure sealing. As long as the spring force is greater than the force Fp generated by the valve inlet pressure, this situation will remain.
