The flapper valve is a system for transporting dust and powdery dry materials. It can cut off the device for transporting materials. It is installed in the lower part of the ash hopper such as economizers, air preheaters, dry vacuum cleaners, flues, etc., of thermal power plants. It can also be used with The electric feeder is used together, the working temperature can reach 200℃, the device is light in weight and small in size.
Socket valves are generally divided into three types: electric, electric, and hydraulic. Socket valve is usually composed of valve body, valve body, valve body frame, screw clamping drive device, expansion joint and valve body walking drive device. The valve plate is composed of a through plate and a blind plate, which controls the flow of the medium and cuts off the floating seat and welds the corrugated expansion joint. The walking drive device moves the valve plate frame to realize the conversion of the through hole valve plate and the non-through hole valve plate. The clamping drive device passes through After the chain drive drives the screw drive to rotate at the same time*, the nut moves the floating seat
Manual flapper valve has the following advantages
1. The fluid resistance is small, and its resistance coefficient is equal to the same length of pipe.
2. Simple structure, small size and light weight.
3. It is tight and reliable. At present, the ball valve sealing material is widely used in plastics and has good sealing performance. It is also widely used in vacuum systems .
4. Convenient operation, fast switching, 90° rotation from fully open to fully closed, and convenient remote control.
5. Convenient maintenance, simple ball valve structure, general movement of the sealing ring, convenient disassembly and exchange.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. A wide range of applications, with a diameter as small as a few millimeters and as large as a few meters, and can be applied to high vacuum to high pressure.
