The Main Role Of Stainless Steel Check Valve

Stainless steel check valve, also known as counterflow valve, check valve, back pressure valve and check valve, is an automatic valve, because it is automatically opened and closed by the force of the medium flow in the pipeline itself. Stainless steel check valves are used in piping systems and can be combined for piping through various working media depending on the material. Its main function is to prevent the backflow of the medium, the leakage of the medium in the container, and to prevent the reversal of the pump and its drive motor.

The check valve on the port pipe is used to prevent liquid backflow, and the back pressure valve is used to maintain a constant pressure at the pump outlet. It can be used as a safety valve in systems with less stringent requirements. Use with the pulsation damper to reduce the damage of the water hammer to the system, reduce the peak flow rate fluctuations, and protect the pipes, elbows, and joints from the impact of pressure fluctuations. Create a good working environment for the metering pump and improve the working performance of the pump.

Ensure the stability of the water flow of the pump, such as the flow of some pumps with the pressure changes, you can set the back pressure valve at the pump outlet, so that the output flow of the pump is stable, then generally choose the pressure of the back pressure valve for the actual use of the pump pressure or slightly less than the use of the pump pressure.

When the pressure of the pipeline or equipment container is unstable, the required pressure of the pipeline can be maintained, so that the pump can output the normal flow.

In the pump outlet due to gravity or other effects often appear artefact or siphon phenomenon, back pressure valve can reduce the flow and pressure fluctuation due to siphon, this time generally choose more than the liquid's own pressure can be, such as to prevent the liquid liquid level of 2 meters in the medicine box, you can choose a pressure greater than 0.02MPa back pressure valve, generally choose 0.1MPa.
