Triple Offset Butterfly Valve
To withstand high temperature, the metal seal must be used, but large leakage; For zero leakage, rubber seal must be used, but not high-temperature resistant. In order to overcome the contradiction of the double eccentric butterfly valve China, the was carried out.
The structural characteristics of the double eccentric eccentric axis of the stem position at the same time, make the butterfly plate type sealing face of the cone axis deflection in the cylindrical axis of ontology, that is to say, after the triple eccentric, butterfly plate sealing section is no longer true circle, but the ellipse, and so the seal face shape asymmetry, tilt to the center line of the ontology, on the other side is parallel to the centerline of ontology. The biggest characteristic of the triple eccentric is fundamentally changed the seal structure and seal position is no longer, but the torque seal, namely not rely on the elastic deformation of the seat, but completely rely on the seat of the contact pressure to achieve sealing effect, thus solved the problem of metal seated zero leakage at a stroke, and because of the contact pressure and the medium is proportional to the pressure, resistance to high pressure high temperature is solved. Are abundant as producers of
