Solution using a self-acting pressure regulator with a controller
Thread Content
Our factory has a Shengao self-acting pressure regulator. I’m a bit confused as to why an additional filter-pressure regulator is installed in the air supply circuit of this self-acting pressure regulator – what is its purpose? Has anyone used it before? Please explain its function and significance!
Damn, it’s going to disappear into the void again. Hasn’t this been used at all? Never mind, I’ll find the answer and come back to share it with everyone
It’s not clear from the diagram; it might be used for online pressure setting of a self-acting pressure regulator!
In terms of function alone, a pressure relief valve should be used to regulate the pressure before and after the control valve – that is, the pressure that one wants to control. Is the controller also known as a pilot valve? It serves to improve control accuracy and speed. I haven’t used it in practice yet; no projects have been carried out on it. I’d like to participate in discussions; this is just for reference
Based on the information available so far, it is primarily used for filtering purposes; more details will be shared later
Your explanation is basically correct; indeed, the controller is designed to improve control accuracy. I just don’t quite understand what the purpose of adding a filter-reducing valve to the pressure inlet pipe is
The main function of the filter pressure regulator is to stabilize the air supply pressure at the membrane head below. The pilot-operated self-acting pressure control valve is a type of pilot-operated self-acting valve that improves the accuracy of valve control.
The pilot-operated self-acting control valve functions similarly to a PID controller, serving to control the speed and accuracy of regulation.
How is this pressure reducing valve adjusted? Is it necessary to adjust it when using it regularly?
Well, your answer is probably quite correct
