It is used for adjusting the pressure of the pump’s safety valve, setting the safe outlet pressure of the pump.
I agree with what everyone said about the pump’s safety valve, but I would like to ask which expert is familiar with the structure of this safety valve
Pump body safety valve, but I don’t understand its structure
This can adjust the large spring inside the pump’s safety valve
Pump body safety valve, used to adjust the pressure at which the safety valve activates; when pressure exceeds this level, the material returns to the pump’s inlet.
This is not a safety valve; it is used to regulate the outlet pressure (flow rate) of the pump. The set pressure of a safety valve is fixed.
