Safety valves and other valves of different

Safety valve is special equipment (boilers, pressure vessels, pressure piping, etc.) a limit on the pressure relief safety play an important role in the annex. Reliability and performance of its action is directly related to equipment and personal safety, and closely related to energy conservation and environmental protection. But the safety valve and other Pilot operated safety valve can play a similar role at times confusing, it should be clear the following points:
1, the safety valve is mounted directly on the special equipment, the management and performance to meet the quality and technical supervision departments and relevant special equipment requirements. It is a static pressure from the valve before the media - driven automatic pressure relief device. Characterized by a sudden opening of the full opening action. For gas or steam occasions.
2, relief valves and patio heater gas valve on the structure and performance similar to his, are more than open automatically discharge pressure inside the media, in order to ensure the safety of the device. Relief valve, also known as relief, is a static pressure from the valve before the media - driven automatic pressure relief device. It opened with the pressure exceeds the force increase proportionally open. Mainly used for fluid applications.
3, safety relief valve, also known as safety relief valve is a pressure-driven by the media automatic pressure relief device. Use different according to both valid for the safety valve is also valid for the relief valve.
4, emissions by the required safety valve, relief valve no specific demands. In general, the safety valve should be more reliable than the relief valve.
