The butterfly plate of wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle of 0 ° - 90 °, which can play the role of flow regulation. When the butterfly plate rotates to 90 °, the valve reaches the maximum opening. The wafer butterfly valve has the advantages of simple structure, small volume and light weight. It is only composed of a few parts. Moreover, it can be opened and closed quickly by rotating 90 °, which is simple to operate. At the same time, the valve has good fluid control characteristics.
① The unique design of three-way eccentricity makes no friction transmission between sealing surfaces, and prolongs the service life of the valve.
② Elastic seal generated by torque.
③ The ingenious wedge-shaped design enables the valve to have the automatic sealing function of closing more and more tightly, and there is compensation and zero leakage between the sealing surfaces.
④ Small volume, light weight, light operation and easy installation.
⑤ Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
⑥ The material of replacement parts can be applicable to various media and can be lined for corrosion protection (lining F46, gxpp, Po, etc.).
⑦ Continuous structure diversification: clamp, flange and butt welding.
The structural length of the valve shall comply with the provisions of gb12221-1989, and the flange connection size shall comply with the provisions of JB / t79-1994
