工作原理：
Working principle
鄂式闸门由本体、扇形闸板、轴、齿轮、密封副、执行机构等部件构成。手动或执行机构推动摇杆，使齿轮带动扇形闸板沿轴心旋转，使两个扇形闸板向两边开启，物料随即下落，待接料装置满载后，再由执行机构带动摇杆，使扇形闸板复位，关闭截断下落的物料。
The valve is made up of body, sector gate, axle, gear, sealing pairs and actuator etc. when the rocker is driven by hａnd or the actuator device, it will drive the gear to make the sector gate rotate and open, then material drop. When the loader is full, the actuator will drive the rocker to replace the sector gate, and then the falling material will be cut off.
使用说明：
Usage explanation
l 安装时请注意闸门本体上标明介质流向。两法兰连接时必需加密封垫片，然后均匀锁紧螺栓。
l 运行时请辨清扇形闸板开关方向，执行机构请正确接线。
l 运行时请定期给各传动部位加润滑油。
l Pay attention to the flow direction of medium marked on the body. Add the sealed shim between the two flanges and then screw down the bolt.
l Pay attention to the open-close direction of the gate when operate. The actuator must be wired exactly.
l Add lubricant to the transmission parts regularly as it runs.
