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.
使用说明：
Usage explanation:
l 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。
l 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。
l 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。
l It can be installed in horizontal or vertical. Sealing gasket must be put on the connected, then equably tight the bolt.
l You can not add assistant lever to the hand wheel. Clockwise turn of hand wheel means the closing of valve, otherwise it means opening.
