Questions regarding pressure-controlled check valves
Thread Content
A constant-pressure check valve is installed between the pump’s outlet pipeline and inlet pipeline. What is its function? Can it be removed? Under what circumstances can it be canceled? Thanks first! :handshake
By understanding the role of check valves at the pump’s outlet and inlet, you can determine whether they can be removed. The check valve at the pump outlet is designed to protect the pump from damage when it is shut down, while the check valve at the pump inlet serves to hold back the medium after the pump is stopped, so that no priming is required when the pump is started again.
This is connected between the pump’s outlet and inlet; it is likely intended to prevent pressure buildup, similar to a safety valve. But I have never seen a design like this before, so I am not quite clear about the specific design rationale and intent.
That’s how it is; you’re right.
Thank you for your attention! :handshake

Is your pump a metering pump or a pulse pump?

Properties of pumps: Generally, for pumps such as metering pumps and reciprocating pumps, there is a pipeline that leads from the pump’s outlet back to its inlet, and a safety valve is installed on this pipeline.
Resolved, thanks for following! It is to prevent the pump from building up pressure after the automatic metering valve closes. Previously, I encountered ones with return pipelines, but this one doesn’t have them, so this valve was designed.
