Why should the safety valve be calibrated? The safety valve inspection company is introduced as follows:

First of all, we should understand the characteristics and functions of the safety valve. The safety valve belongs to the active valve of special equipment. It can generally be divided into full lift safety valve, micro lift safety valve, and medium lift safety valve according to the opening height of the safety valve (this kind of application is relatively rare).

    ARI The safety valve inspection company told us that both full lift safety valves and micro lift safety valves are installed on pressure equipment. When the pressure in the equipment exceeds the set pressure value, the tension spring of the safety valve will lift the valve stem to release pressure outward. When the pressure recovers to the working pressure in the system, the safety valve will actively close again to prevent the normal working pressure inside the system from leaking out.

ARI safety valve The inspection company introduced that the safety valve is generally in the normally closed state. Once the pressure rises beyond the additional pressure requirements, the safety valve must be opened normally for pressure relief. If the opening pressure of the safety valve is inaccurate, too high or too low, the equipment will not work normally. Especially if the safety valve is not opened when the pressure exceeds the range, the equipment will be defective or burst, Cause safety of equipment and personnel. Therefore, the safety valve must be calibrated by a professional third-party organization according to the planned opening pressure before being installed into the equipment. This is a job that must not be sloppy.

The safety valve inspection company introduced that the calibration can only be installed on the equipment within the allowable range of the national standard operation, otherwise it must be reworked and manufactured from scratch.
