LZ螺旋闸门

        LZ系列螺旋闸门用于建材、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，切断迅速的设备。
        LZ series screw gate is used in top silo, bottom silo, inlet and outlet etc. of building material, metallurgical, ore, electric power, chemical industry, glass, light industry and foodstuff etc.

结构特点：
        LZ螺旋闸门结构简单、操作灵活、重量轻、无卡阻、切断快，适用于各类无粘度的固体、粉料及小于Φ10mm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型为链轮。单向和双向两种结构形式，LZD为单向、LZS为双向。

Structure characters
It is characterized by simple structure, sensitive operation, light weight, no blockage and quick cutting, especially for all of no clay liquid and powder material and less than <t>1 Omm grain material, conveyed crystal material, flow adjustment. The installation is not limited by the angle. It is convenient to operation and adjust the open mouth at any time. The valve has hand wheel and chain wheel. I is hand wheel and II is chain wheel. Two structures are single way and two-way. LZD is single way and LZS is two-way.
 

工作原理：
        LZ螺旋闸门主要由框架、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。

Main principle
It is composed of frame, valve plate, silk pole and nut etc. Drive hand wheel in hand and make silk pole move back and forth togather nut of silk pole and valve plate. And realize to start and open it.

使用说明：

• 本阀可水平安装或垂直安装，安装时两法兰间必须加密封垫片，然后均匀锁紧连接螺栓。

• 操作时顺时针旋转为开。不得在手轮上再增加辅助杠杆。

• 长期存放时应使设备处于关闭状态，各传动部位加润滑油，不允许露天存放或堆置。

Application description
• The valve may be installed in horizontal or vertical. Add gaskets between two flange connections when installation, then lock the bolt.
• When operation, hand wheel is rotated in clockwise which is in closed. On the contrary it is on. Not allow to add appendix lever.
• If it is stored for a long time, the equipment should be in closed condition. All driving position should be added grease. Not allow to put in open air or pile.
