SCREW GATE VALVE
螺旋闸门用于建材、冶金、矿山、电力、化工、玻璃、轻工、粮食等行业的库顶、库底及进出口等。是控制流量变化较大，启动频繁，切断迅速的理想设备。
This valve is widely used at the top and bottom of store house and carry port in metallurgical, mining, building material, food, chemical industries etc. It is the ideal equipment to control a great changing flow, to open and close frequently and to stop quickly.
Structure characteristic:
结构简单、操作灵活、重量轻、无卡阻、切断快，特别适用于各类无粘度的固体、粉料及小于 Φ 10mm 的颗粒料，晶粒料的输送及流量调节，安装不受角度限制， 操作方便， 能随时调节开度。该阀门有手轮和链轮操纵两种操作形式， I 型为手轮， II 为链轮。单向和双向两种结构形式， LZD 为单向、 LZS 为双向。
This valve is simple in structure, handy to operate, light in weight, non-obstructive and quick to stop. It is suitable to be used to carry all kinds of solid material, particle and crystal particle whose diameter is below 10mm and to adjust the flow. It can be installed at any angle and operated handily. The size of its gate can be regulated at any time. This valve has two type of operation. One is manual wheel operation; the other is chain wheel operation. Ⅰ means manual wheel. Ⅱ means chain wheel. The valve has two type of construction LZD is signal direction and LZS is double direction.
Working principle
主要由框架、闸板、丝杆、螺母等零件构成，用手转动手轮使丝杆带着丝杆螺母和闸板沿水平方向往复运动，达到闸门的启闭目的。
It is mainly made up of frame, gate board, screw pole, nut etc. Rotate the handwheel by hand, then the screw pole drives the nut and gate board move in horizontal to and fro to open or close the valve.

sage explanation:
本阀可水平安装或垂直安装 ， 安装时两法兰连接中间必须加密封垫片 ， 然后锁紧螺栓。操作时手轮顺时针旋转为阀关，反之为开，不得在手轮上再增加辅助杠杆。若长期存放应使设备处于关闭状态，各传动部位应加润滑油，不允许露天存放或堆置。
It can be installed in horizontal or vertical. Sealing gasket must be put on the connected, then equably tight the bolt.
You can not add assistant lever to the hａnd wheel. Clockwise turn of hａnd wheel means the closing of valve, otherwise it means opening.
The device should be in the shut-down if the valve-board is placed longer. Driving parts should add lubricated oil. Placing in the open air and piling up is not permitted.
