LZ Spiral gate

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.

Ⅱ、Structure characteristics
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.

Ⅲ、Working principle
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.

The number of chain M = 0.105x-113 (x is the height from the ground screw)

Ⅴ、Directions for use
1. It can be installed in horizontal or vertical installation, connection must add sealed shim between the two flanges and then lock bolt.
2. The operation is clockwise rotation of hand wheel means the closing of valve, otherwise for open, may not add assistant lever again on the handwheel.
3. The device should be in the shut-down if the valve-board is state, the driving parts should add lubricated oil, should not be piled up in open air.
