Flange single disc swing check valve adopts inner-installed rocker swing structure, and all hoist parts are installed interior, without penetrating body. In addition to the middle flange part uses sealing gasket and sealing ring, the whole parts are no leakage, to eliminate the possibility of valve leakage. The rocker and disc connection part use spherical connecting structure, making the disc have a certain free degree within the scope of 360 degree, and have appropriate compensation for the trace position. The Valve has been widely used in chemical industry, metallurgy, pharmaceuticals and other fields.
