Back pressure valve adjustment

1. The one-way valve on the outlet pipe is used to prevent liquid backflow, and the back pressure valve is used to maintain a constant pressure at the pump outlet. 2. It can be used as a safety valve in systems with less stringent requirements. 3. Used in conjunction with pulsation dampers to reduce the harm of water hammer to the system, reduce the peak value of flow velocity fluctuations, and protect pipelines, elbows, and joints from the impact of pressure fluctuations. 4. Create a good working environment for the metering pump and improve the working performance of the pump. 5. Ensure the stability of the pump's water flow. If the flow of some pumps changes greatly with pressure, a back-pressure valve can be set at the outlet of the pump to stabilize the pump's output flow. In this case, the pressure of the back-pressure valve is generally selected to be the actual operating pressure of the pump or slightly less than the operating pressure of the pump. 6. When the pressure in the pipeline or equipment container is unstable, the required pressure of the pipeline can be maintained so that the pump can normally output flow. 7. Self-flow or siphonage often occurs at the water outlet of the pump due to gravity or other effects. The back-pressure valve can reduce the flow and pressure fluctuations caused by siphonage. In this case, the pressure is generally greater than the pressure of the liquid itself. For example, to prevent the liquid from flowing in a medicine box with a liquid level of 2 meters, a back-pressure valve with a pressure greater than 0.02MPa can be used. Generally, 0.1MPa is sufficient.

I have never heard of a back pressure valve and don’t know much about it.

For example, the set point I need is 10MPA. In the process of adjusting this set point, how can I be sure that this point is reached?

Tighten the pressure regulating screw of the back pressure valve to achieve the desired pressure value

Hmm, yes, but how to confirm that the pressure value has been reached?

I don’t know the specific design, but I just want to know how to implement it. If a pressure gauge is used, can only the front-end pressure gauge be implemented? How to implement it? How to achieve this if there are pressure gauges at the front and rear? Please let me know, thank you
