The two-way hard-seal butterfly valve can also add a water sealing device in the middle of the valve body. It can fill the middle cavity with water in an emergency or during pipeline maintenance, playing the role of safety guarantee and dual-purpose valve.
The wedge-type two-way metal seal butterfly valve adopts a double butterfly plate full cone sealing surface structure, which can realize the continuous grinding and self-correction of the butterfly plate sealing surface and the valve body sealing surface during the switching process of the valve, thereby improving the service life. During the operation process, the medium pressure helps the valve open, so the operating torque is reduced.
Therefore, the sealing structure of the two-way metal seal butterfly valve is novel and unique. The double butterfly plate has a two-way sealing function, so it is more suitable for high temperature and high pressure working conditions. The valve has good processing technology and low design and manufacturing costs. It is a hard-sealed butterfly valve suitable for high-tech parameters and high-performance industrial conveying systems.
