The D971X electric clamp type soft seal butterfly valve adopts a double eccentric structure, which has a sealing function that becomes tighter as it is closed, and the sealing performance is reliable. The sealing auxiliary material is paired with stainless steel and nitrile oil resistant rubber, which has a long service life. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media for users to choose from. The butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance. The overall baking paint can effectively prevent rust and can be used in different media as long as the sealing material of the valve seat is replaced. The D971X electric clamp butterfly valve has bidirectional sealing function, which is not controlled by the flow direction of the medium or the spatial position during installation, and can be installed in any direction. This valve has a unique structure, flexible operation, labor-saving, and convenience.
Structural characteristics and applications of electric clamp type soft seal butterfly valve
The D971X electric clamp butterfly valve adopts a clamp center plate structure, mainly composed of a valve body, valve plate, valve shaft, valve seat, and transmission device. The structure is simple, compact, small and lightweight, and easy to transport, install, and disassemble; 90 ° opening and closing, quick switching, low operating torque, labor-saving and lightweight; Good sealing performance, long service life, and can achieve zero leakage; Its flow characteristics are similar to a straight line, with good regulation performance. The D971X electric clamp butterfly valve is sealed with rubber. When closed, the sealing performance between the butterfly plate and the valve seat is good, with excellent bidirectional sealing performance and low torque value. The valve maintains 100% zero leakage under working pressure, and the friction between the butterfly plate and the valve seat seal is small. The valve is driven by the valve shaft to rotate the valve plate 90 degrees. The butterfly plate opens and closes flexibly, without jamming or jumping, and has low torque. Purpose: The soft sealed center line clamp butterfly valve developed by Shanghai Qigao Valve Manufacturing Co., Ltd. has a compact structure with double eccentric flange butterfly valve, easy 90 ° rotary switch, reliable sealing, and long service life. It is widely used in water plants, power plants, steel mills, papermaking, chemical, textile, food and other water supply and drainage, gas pipelines to regulate flow and intercept media.
