Safety valve working principle and function:
The diaphragm and valve core are pressed against the valve seat by internal springs. When the pressure in the system pipeline exceeds the preset pressure, the diaphragm and valve core are lifted, and the medium leaks out to the reflux pipe and container. The pressure can be set within the range of 0-1.0Mpa by adjusting the screw on site, and the pressure release is generally set higher than the system pressure by 0.1-0.2Mpa. The installation should be as close as possible to the outlet of the pump, and there should be no valves between the pump and the safety valve.
Main features of safety valve:
1. Pressure-releasing component of the pipeline, releasing pressure to ensure stable system pressure
2. Automatically open when the pressure is too high, safely release the medium and discharge it to the suction pipe or chemical container
3. Protect the safety of the pump and the normal operation of the system
4. Protect pipelines, elbows, and joints, reduce the impact of pressure fluctuations
Safety valve performance parameters:
Caliber DN15mm-DN40mm
Operating pressure 1.0Mpa
Safety valve 0.05-1.0Mpa
