Drive through the valve rod and rocker arm make valve disc rotating certain Angle to the realization of the valve switch. Valve sealing surface with spring and valve seat close joint, spring pressure is always make valve close joint in the seat, and allow valve sealing surface in the vertical direction on the displacement. This will help compensation valve parts caused by heat bilges cold shrink deformation and multiple switch form trace wear and overcome any back pressure changes on the influence of the seal and prevent particle medium into between sealing surface; In the disc valve opening and closing process, the seat seal in the face of valve disc in the tangential direction of friction force difference, the valve plate in a circular opening and closing process of rotation and can continuously shear and cleaning in the process of accumulation of possible in cavity medium, these features are other valve class do not have.
1, seat. Vertical flow direction of the wide seat, flow direction wear and erosion will not affect the sealing.
2, the valve plate. Rotary shear disc spin, from grinding and enhance seat from cleaning ability, shear through the valve of solid medium.
3, spring. Temperature and pressure compensation caused by the fluctuation of packing stress change, to maintain the uniform stress and prolong the life of the packing.
4, packing. Multiple V PTFE or graphite ring and high carbon packing.
5, double sleeve. Spray design, at the same time provides a stable airtight packing space.
6, valve plate compensation spring and spring column. Compensation valve disc and seat wear, and resist back pressure, prevent material into the sealing surface.
7, blowing hole. To optimize the purging design, can be the most effective purge accumulation of material.
Disc valve can be in many industries have a wide range of applications, such as metallurgy, mining, power plant, coal gasification, coal liquefaction, glass, ceramic, oil field, refining industries of lock hopper, bin, reaction kettle, separator, pneumatic conveying, pump isolation and all kinds of pipes, especially in wear and erosion media applications, disc valve more can show its outstanding performance.
