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. 工作原理： 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. 适用温度 80（℃） 压力范围 1.O（Mpa） 适用介质 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 公称通径 200-200（mm） 主体材料 铸钢 连接形式 法兰 产品别名 螺旋闸门（插板阀） 适用范围
