The safety valve is a special valve in which the opening and closing member is in a normally closed state under the action of an external force. When the pressure of the medium in the equipment or the pipeline rises above a specified value, the medium is prevented from exceeding the specified value by discharging the medium outside the system. . Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. Note The safety valve must be pressure tested before it can be used.
Safety valves provide safety protection in the system. When the system pressure exceeds the specified value, the safety valve is opened, and a part of the gas/fluid in the system is discharged into the atmosphere/pipe, so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not cause an accident due to excessive pressure.
The common safety valves generally have the following types:
1. According to the overall structure and the loading structure, it can be divided into three types: heavy hammer lever type safety valve, spring type safety valve and control type.
2. According to the ratio of the valve opening height to the valve circulation diameter, it can be divided into a micro-open type and a full-open type safety valve.
3. According to the way of safety valve gas discharge, it can be divided into three types: fully enclosed, semi-closed and open.
