                • Ordering Process

                Y44H bellows pressure reducing valve is used in the pipeline of steam, air and water without corrosive medium whose temperature is below 200 C, so that the pressure of medium passing through the valve body can be kept constant to meet the needs of work. The inlet pressure P1 is 1.0-0.1 MPa, the outlet pressure P2 is 0.4-0.05 MPa, and the pressure difference between the front and back of the valve is not less than 0.6 MPa, nor less than 0.05 MPa.


                Action principle and structure elucidation


                1. The inlet medium pressure enters the body cavity from the opening clearance between the disc and the valve body sealing ring to make the medium pressure flow through the bellows combination box. The bellows and springs are compressed by the medium pressure. The disc closes the valve body sealing ring with the displacement of the valve stem. The media in front of the valve is cut off without the medium pressure behind the valve. The supplement. When the pressure of the medium behind the valve decreases, the bellows are deformed by the radial force of the adjustable spring, and the valve stem jacks the disc. The medium can be reduced by pressure through the valve body sealing ring.


                2. Bellows pressure relief valve is composed of valve body, valve cover, disc, valve body sealing ring, stem, bellows, regulating spring and other parts, body cavity inlet assembly disc, valve body sealing ring and auxiliary spring, auxiliary spring is to maintain disc and valve body sealing ring automatic sealing, outlet body cavity assembly elastic sealing element (bellows) Ensure the leakage of medium pressure after the valve and compensate for the non-uniformity of pressure. The screw is to adjust the working performance of the spring loaded pressure reducing valve.
