High temperature characteristics of pneumatic valve ball

high temperature characteristic of the pneumatic valve is: ball pneumatic seat sealing by soft t-shaped sealing ring on both sides of the multi-layer pieces of stainless steel.
high temperature of the pneumatic valve pneumatic ball valve plate with pneumatic valve 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 pneumatic ball 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 ( Medium flow direction and disc rotating at the same time, the direction of 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.
when the current state, high temperature pneumatic ball valve of pneumatic valve plate and between the pneumatic valve seat seal on drive torque pneumatic valve plate pressure to the pneumatic valve seat. , with the increase of reverse medium pressure pneumatic valve plate and the positive pressure pneumatic seat between units is less than the medium pressure, adjust the ring after the loading of the spring deformation energy stored by compensation pneumatic valve plate and valve seat sealing surface of the tight pressure automatic compensation effect.
so the utility model is not like the existing technology, soft hard multi-layer sealing ring, installed in the pneumatic valve plate directly installed on the pneumatic valve body, in the middle of the clamp and pneumatic seat add adjustable ring is the ideal way of two-way hard seal. It will replace the brake pneumatic valve, pneumatic valve and ball.
