Flange type safety back pressure valve

Flange type safety back pressure valveIntroduction:

Installed on the positive pressure discharge pipeline of the metering pump to prevent siphon phenomenon and eliminate changes in the dosage caused by pressure fluctuations at the injection point. Remove the protective cap on the adjustment screw on site, rotate the adjustment screw, and use the pressure gauge in the pipeline to adjust the required pressure. The screw can be adjusted between 0-0.6MpaSet back pressure within the range. When used in conjunction with pulse dampers, it reduces the damage of water hammer to the system, maintains a certain constant pressure from the pump outlet to the back pressure valve, and keeps the system flow rate constant.

Introduction to flange safety valve:

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 return pipe and container. On site, screws can be adjusted to regulate the pressureUtilize the pressure gauge in the pipelineat0-1.0MpaSet the pressure within the range, and the release pressure is generally set higher than the system pressure0.1-0.2Mpa,The pressure regulation of the safety valve is not allowed to exceed the maximum pressure of the metering pump. It is generally installed as close as possible to the outlet of the pump, and there should be no valve between the pump and the safety valve. Protect the safety of the pump and ensure the normal operation of the system.
