High temperature adjustment problems of pneumatic valve use

pneumatic valve plate and seat sealing surface for the oblique cone structure, in the pneumatic valve plate oblique cone surface welding heat resistance, corrosion resistant alloy material; Fixed between the adjusting ring clamp spring together with the clamp on adjusting bolt assembly structure. This structure can effectively compensate the body between the collar and pneumatic tolerance zone and pneumatic valve stem under medium pressure elastic deformation, solved the pneumatic valve in the two-way exchange medium sealing problems exist in the process of delivery. High temperature butterfly pneumatic valve adopts soft T on both sides of the multi-layer stainless steel pieces of sealing ring, with metal sealing and soft sealing the dual advantages of under low temperature and high temperature circumstances, all with zero leakage sealing performance. Trials show that pool is flow state, the sealing surface pressure is the drive torque and the medium pressure in the role of the pneumatic valve plate. Positive pressure medium pneumatic valve plate oblique cone surface and pneumatic valve seat sealing surface squeezed tight, sealing the better the results.
