The wafer type elastic hard sealing butterfly valve adopts a “U” type stainless steel sealing ring, which is in three-dimensional eccentric contact with the polished butterfly plate. It solves the disadvantage that the sealing surface of the traditional eccentric butterfly valve is still in sliding contact friction at the moment of opening and closing 0°~10°, and realizes the effect that the sealing surface of the butterfly plate is separated at the moment of opening and the sealing is closed when the contact is closed, so as to prolong the service life and achieve better sealing performance. good purpose.

Wafer type elastic metal hard sealing butterfly valve is simple in structure, compact, light in weight, easy to install and disassemble, and easy to maintain;
2. The butterfly valve adopts stainless steel “U”-shaped sealing ring, which has a certain elasticity. It has excellent sealing performance with the butterfly plate under high temperature and low temperature;
3. The three-dimensional eccentricity of the butterfly valve has been strictly calculated, and the “U”-shaped sealing ring and the butterfly plate have almost no friction, have a long service life, and have the function of the tighter the closer it is;
4. The sealing surface of the butterfly plate is made of surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life;
