Worm Gear Driven Cast Iron Material Pin-Less Wafer Butterfly Valve

Introduction

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.

Structural features of wafer butterfly valve

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
