Tilting Disc Buffer Wafer Type Check Valve


Working principles: the valve seat of the tilting disc check valve is a part of the inclined circular cone,The sealing line formed between the seat and the valve disc is approximately elliptic curve. The Angle between the plane of the curve and the center line of the valve flow passage is 60°.The center of the long axis of the approximate elliptic seal line forms an Angle eccentricity with the axis of the cone, that is, the axis of the national cone where the sealing surface of the seat is located and the center line of the valve body flow passage form a second eccentric Angle of 15°-20°.The axis of the disc rotation axis forms an eccentricity relative to the axis of the circular cone, and is also in an eccentric position relative to the plane where the sealing line is located, forming an eccentricity.When the pressure of the medium to its working pressure, the disc opens, when the pressure of the medium reduced, butterfly disc disc automatically closed.The disc and metal seats feature a triple eccentric 'butterfly' valve, which enables the disc to perform bell pendulum motion.Disc bevel seats and funnel discs are free of friction or trickle contact during bonding and separation. On closing, they are quickly and almost impact-free from the seat without the aid of Spinner.Seal without collision.
