The principle and working mechanism of spring type safety valves

Spring type safety valve is a common safety control equipment in pressure pipeline systems. Its main function is to automatically open and release excess pressure when the internal pressure of the pipeline exceeds the set safety pressure, ensuring the safe operation of the system. The working principle and mechanism of spring type safety valves are very important.

The working principle of spring type safety valves is based on the following key points:

1. Spring: The spring inside the valve is a key component of the spring type safety valve, and its elastic effect determines the opening and closing pressure of the spring type safety valve. When the pressure inside the pipeline exceeds the set safety pressure, the spring inside the valve will deform, causing the valve to open and release excess pressure.

2. Sealing mechanism: Spring type safety valves usually adopt various shapes such as spherical, cylindrical, and conical, and adopt a spring and pressure balance structure to flexibly and automatically adjust the opening force of the internal valve, providing effective safety control.

3. Adjustment structure: By strengthening the form of needle insertion, the pressure range of the spring type safety valve can be adjusted to adapt to different pressure conditions and usage environments.

In summary, the working principle of spring type safety valves is mainly based on the elastic deformation of the internal spring of the valve and the sealing control of the valve. When the pressure inside the pipeline exceeds the set safety pressure, the valve will automatically open, ensuring the safe operation of the pipeline system by releasing excess pressure.
