Quick unloading valve works
The principle of fast unloading valve It is connected to the upper part of a cup of slide valve, the lower chamber of the valve and the lower part of the piston of the high-pressure oil motive fluid communicating, and by the role of high-pressure oil in the bottom of the cup valve slide valve in the middle There is a small hole, so that a small amount of pressure oil flow to the upper part of the spool of the oil chamber, the oil chamber has two, all the way through the check valve and the emergency cut off the oil connected to the normal operation due to cut off the oil on the main oil pressure equal to high pressure Oil pressure it withstand the check valve and make it close, the upper part of the slide valve pressure oil can not vent from this road, the other oil through the needle valve control of the shrinkage hole, control the oil chamber to pass through the piston Of the oil channel, regulating the opening of the needle valve can adjust the hydraulic pressure on the spool for debugging purposes. In normal operation, the upper part of the slide valve with the force of the spring plus the spring force is greater than the force of the lower part of the slide valve to make the slide valve of the cup slide on the base, and the port of the connecting oil return line is closed. When the steam turbine is faulty Solenoid valve action, cut off the oil pipe loss of pressure, the role of the cup-shaped slide valve on the top of the open check valve and drain, so that the valve sharp decline in oil pressure, the lower part of the high-pressure oil to promote sliding valve slide, slip The upper drain port of the valve sleeve is opened, so that the high pressure oil in the oil motor loses its pressure and rapidly drops under the action of the spring force. The main steam valve is closed and the unit is shut down. More Keywords Search: Valve
