This valve used in building material, metallurgy, mining, power, chemical industry, glass industry, light industry, food industry and so on such as the top and bottom of the storeroom, import and export, etc. It is the ideal equipment to control a great changing flow, frequent restart and to cut off.
Simple structure, flexible operation, light weight, no jam, fast cutting, especially suitable for all kinds of solid, powder without viscosity and less than Φ10 mm grain, grain material conveying and flow control, installation angle is without limit, easy to operate, can adjust the opening at any time. There are two kinds of operation form of valve,it is handwheel and sprocket wheel, type I is the handwheel, II is the sprocket.There are unidirectional and bidirectional two kinds of structure forms, LZD is one-way, LZS is two-way.
The valve is mainly composed of frame, gate, screw, nut and other parts, turn the handwheel by hand make screw move with the screw nut and valve board along with the horizontal reciprocating motion, achieve the aim of opening and closing gate.
