Features
he triple eccentricity refers to the addition of an angular eccentricity on the basis of the double eccentric structure, say, the sealing surface of the butterfly valve is inclined and tapered. Triple eccentric butterfly valve is also called triple offset butterfly valve. We can produce two types, one is triple eccentric multi-layer sealing butterfly valve, and the other is triple eccentric all-metal sealing butterfly valve.
The triple eccentric multi-layer sealing butterfly valve is accomplished by the elasticity of the sealing ring on the valve plate, and the elasticity of the sealing ring is produced by its radial compression and flexibility. The contact surface between the sealing ring and the valve seat is an oblique cone. The contact angle between the sealing ring and the valve seat produces a slight "wedge effect" to make the sealing ring flexible and radially compressed. It is precisely because of the uniform contact between the valve seat and the sealing ring and the flexibility of the sealing ring that the load on the valve seat is even, so that the tightest cut-off can be achieved with the smallest torque. The elasticity generated by the torque makes the valve close tightly, regardless of the flow direction of the medium or the force of the medium.
