High temperature butterfly valve
- Feb 03, 2018 -

As a component used to realize on-off and flow control of pipeline system, it has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. In the well-known butterfly valve technology, the sealing structure adopts the sealing structure, the sealing material is rubber, polytetrafluoroethylene and the like. Due to the structural characteristics of the restrictions to adapt to high temperature, high pressure and corrosion-resistant, anti-wear and other industries. A more advanced butterfly valve is a three-eccentric metal seal butterfly valve, the valve body and the valve seat as a single component, seat sealing surface layer surfacing temperature, corrosion resistant alloy material. Multi-layer soft stacked ring fixed to the valve plate, this butterfly valve compared with the traditional butterfly valve with high temperature, light operation, opening and closing without friction, closed with the torque of the transmission mechanism to compensate for increased sealing, improved butterfly valve The sealing performance and extend the service life of the advantages.
