Powder mixing station pneumatic discharge valve pneumatic powder mixing plant discharge butterfly valve body is made of lightweight die-cast aluminum alloy high, the disc is lined with wear-resistant steel core polymer materials, and wear-resistant rubber seals soft seal makes it ideal for the formation of various interest powder, granular materials applications, especially for highly abrasive materials. In need of gravity blanking or pneumatic conveying powder, granular material handling systems, butterfly valves are often installed in hoppers, silos, screw conveyor outlet and gas delivery pipeline. Powder mixing station pneumatic discharge valve double flanged butterfly valve with two identical flange; while the lower single flange butterfly valve is connected with a protruding ring for mounting sleeving. Depending on the application requirements, you can handle alone drive or optional cylinder drive kit. Industrial design with the use of a special composite material to make the butterfly valve has a compact and lightweight structure, miserable plate wear, long seal life, easy installation and maintenance, etc., is a cost - highly effective powder valve. Powder butterfly cement warehouse roof ESP, an important body mixing station precipitators, and general butterfly butterfly plate installed on the pipe diameter direction. Cylindrical channel in the valve body, disc-shaped disc around the axis of rotation, rotation angle between 0 ° ~ 90 °, rotated to 90 °, the valves are open all license conditions. Butterfly simple structure, small size, light weight, only by a few parts. And just rotate 90 ° to quickly open and close, easy to operate, while the fluid control valve has good features. Butterfly valve in the fully open position, the disc thickness is only resistance medium flows through the valve when the pressure generated by the valve drop is small, it has a better flow control characteristics. Advantages mixing station pneumatic discharge valve of a powder, open and close easily and quickly, saving, fluid resistance, can often operate. 2, simple structure, small size and light weight. 3, can carry mud accumulation of fluid in the pipe mouth least. 4, low pressure, can achieve a good seal. 5, regulated performance
