the meter calculates and analyzes to obtain the valve opening value when the piping system reaches hydraulic balance. 2. Differential pressure valve 1. Function: The differential pressure valve is used in the sealing oil system to adjust the air side sealing oil pressure, so that it always maintains a certain pressure difference with the gas pressure in the generator. 2.

Structure and working principle: This valve drives the sliding rod to move up and down through the difference of the input signal, and changes the opening of the valve to adjust the oil pressure. The sealing oil system is usually equipped with two differential pressure valves.

One differential pressure valve is the air side oil pressure regulating valve. It is connected between the inlet and the outlet of the air side oil pump and acts as a bypass pressure regulator. The signals are taken from the machine respectively. Internal hydrogen pressure and air side sealing oil pressure, the valve can automatically adjust the bypass flow according to the pressure change of the signal source, so as to ensure that the air side sealing oil pressure is always higher than the internal hydrogen pressure by 0.085MPa. The other differential pressure valve is the spare pressure regulating valve for air side oil, which is connected to the air side high pressure and low pressure standby sealing oil pipelines.

The signals are respectively taken from the hydrogen pressure in the generator and the air side sealing oil pressure, and the standby sealing oil is adjusted. Flow rate to ensure that the backup air side sealing oil pressure is always higher than the air pressure in the machine by 0.056MPa. 3.

The working Composite Pipe Suppliers of the differential pressure valve in the sealing oil system. The piston of the differential pressure valve introduces the hydrogen pressure in the machine (pressure p1), and the air side sealing oil (pressure p) that is adjusted and output is introduced under the piston.
