The function of solenoid valves
Thread Content
I would like to ask the teachers here: What is the function of an electromagnetic valve installed on the return water pipe of a heating unit, assuming that there is also a safety valve on that return water pipe? I’m not sure exactly what purpose the electromagnetic valve serves; it’s for emergency use. .
First, check whether it is an electromagnetic valve equipped on the control valve; in my opinion, it probably serves mainly to enable or disable the flow~~
A technician I spoke to said it’s used for pressure release and waste discharge; what do you think?
Is it pressure-controlled? I’m not exactly sure; its main function is automatic on/off operation. If it’s used in conjunction with a pressure sensor or other devices to control a certain parameter, I think that’s what it does
Oh, I’m not very familiar with this thing. Thanks for the explanation.
The solenoid valve in the return pipe of the heating heat exchange unit is generally used for pressure relief; it depends on whether its outlet is connected to a drain channel or a water tank The discharge pressure is slightly lower than that of the safety valve; it represents electronic pressure relief and can be used in conjunction with the safety valve. The working principle is the same as that of constant-pressure water make-up equipment.
