What is the working principle of the first angle valve on the outlet pipeline of a propane refrigerator?
Thread Content
The basic process is that the output flows through this angle valve, then through the angle valve with a handle, and is then discharged? So what is the working principle of the first angle valve? What is the purpose of the two thin lines?
I guess it’s a differential pressure control valve; the two thin tubes are used to take pressure samples upstream and downstream of the control valve, and it is the differential pressure that controls the opening degree of this angle valve
