Flange butterfly valve seat made of synthetic rubber. When the disc is closed, the butterfly plate external circular lid pressure to squeeze the synthetic rubber seat, seat produce elastic deformation, the formation of elastic force as sealing pressure, to ensure that the butterfly valve sealing. Flange butterfly valve structure of the three major characteristics: 1. Flange hard seal butterfly valve seat sealing by soft t-shaped sealing ring on both sides of the multi-layer pieces of stainless steel. 2. plate and Industrial Valves seat sealing surface for the oblique cone structure, the 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 tolerance zone between sleeve and body and the elastic deformation of the stem under medium pressure, solve the valves in the process of the two-way exchange medium conveying the sealing problems. 3. 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. Flange butterfly valve of the nine major characteristics are as follows: 1. Small volume, light weight, easy disassembly, assembly and maintenance, can be installed in any position. 2. Simple structure, compact structure, low torque, rotate 90 °. 3. Flow curve tending to straight line, good regulation performance. 4. Butterfly plate without pin structure is used to connect with the valve stem. 5. Butterfly plate adopts the cylindrical spherical shape and improve the sealing performance and prolong the service life of the valve, the pressure to keep zero leakage of more than 50000 times. 6. The seal can be replaced, sealing of two-way sealing is reliable. 7. Can spray disc according to user requirements, such as nylon or teflon. 8. The valve can be designed to flange and clamp connection. 9. Can choose manual, electric or pneumatic drive mode. Flange butterfly valve is suitable for the temperature of 120 ℃ or 150 ℃ or less, or less nominal pressure 1 or less. 6 mpa water supply and drainage, sewage, food, heating, gas, shipping, water and electricity, metallurgy, energy systems, textile and other industries. Especially suitable for two-way sealing and body corrosion. Trials show that pool is flow state ( Medium flow direction is same as the rotation direction of the butterfly plate) When the sealing surface pressure is the drive torque and medium pressure in the valve plate. Positive medium pressure Industrial Valves plate oblique cone surface and valve seat sealing surface squeezed more tightly, sealing effect is better. When the current state, between the valve plate and valve seat sealing pressure on drive torque make the valve plate to the seat. As the reverse medium pressure increases, the unit is pressure between the valve plate and valve seat is less than the pressure of medium, the adjusting ring after the loading of the spring deformation energy stored by compensating valve plate and valve seat sealing surface of the tight pressure automatic compensation effect.
