Questions about pressure relief valves and throttle valves
Thread Content
The function of each, namely the pressure reducing valve and the throttle valve, is achieved by increasing local resistance; therefore, pressure reduction and flow rate regulation occur simultaneously. Why is it said that the flow rate remains constant during pressure reduction, and the pressure difference remains constant during flow rate regulation? How is this achieved? I hope the Bernoulli equation can be used to explain this
Bro, when a pressure reducing valve is in operation, the flow rate generally increases as the opening degree of the valve increases. However, the pressure difference before and after the valve remains constant (it may change slightly, but according to theoretical design it stays unchanged).
Same question – please, experts, answer it
