Y44H Bellows Pressure Reducing Valve instructions

Y44H Bellows Pressure Reducing Valve produced and sold by Baigang valve group,For temperature below 200 ℃ in steam, air, water, non-corrosive medium pipeline, so that through the body of the medium pressure remains constant to meet the needs of work. P1 before the valve inlet pressure from 1.0-0.1MPa, after the bellows relief valve outlet pressure P2 is 0.4-0.05MPa, the pressure difference between the valve before and after the valve is not more than 0.6MPa, nor less than 0.05MPa.

Y44H Bellows Pressure Reducing Valve use principles and structure instructions

1, the media before the valve inlet pressure from the valve flap and the body open the gap into the body cavity so that the media pressure flow corrugated pipe portfolio box, bellows and the spring due to compression of the media pressure and compression, the valve flap with the valve stem Displacement, the valve flap to produce the closure of the valve body, the media before the valve deadline, after the valve does not make the media pressure supplement. When the pressure of the medium after the valve is reduced, the bellows is deformed by the diameter of the adjusting spring, causing the bellows to be deformed. The valve stem opens the valve flap. Reducing the pressure of the media after the valve has been filled with the valve body gasket.

2, Bellows pressure reducing valve is composed of valve body, valve cover, valve flap, valve body sealing ring, valve stem, bellows, adjusting spring and other parts. The body cavity inlet is assembled with valve flap, valve body sealing ring and auxiliary spring, Auxiliary spring is to keep the valve flap and body sealing ring automatic seal, outlet body cavity assembly elastic sealing element (bellows) that is to ensure that the valve after the media pressure leakage and to overcome the pressure non-uniform compensation. Screw is to adjust the spring load pressure relief valve performance.
