鄂式闸门

JAW GATE VALVE

鄂式闸门适用于堆比重≤ 2.5t/m 3 的各类矿石、煤炭、焦炭、灰渣、化工产品等散状物料，广泛应用于建材、冶金、化工、玻璃等行业的仓底卸料。

The valve is widely used in building material, metallurgy, chemical and glass industries etc to discharge at the bottom of storage. It is suitable for loosing material whose conglomeration specific gravity is less than 2.5t/m 3 such as all kinds of ore, coal, coke, dust slag and chemical product.

结构特点：

Structure characteristic:

鄂式闸门采用优质碳钢焊接成形，结构独特，运行灵活可靠，无卡阻现象。配用不同的传动装置能满足不同的工况需要。电动鄂式闸门采用带有超载保护装置的电动推杆，可避免烧坏电机，可以远距离操纵或程序控制，往复行程可以精确调节位置自锁。电液动鄂式闸门采用电液推杆，全液压传动，推拉力均可实现无级调速。气动鄂式闸门采用气动推杆，通过配件组合可以远距离操纵或现场控制。 SEF为手动，DEF为电动，YEF为电液动，QEF为气动。

The valve is welded in fine steel, having the features of peculiar structure, non-obstruction, reliable and flexible operation. It can meet different working condition equipped with different transmission devices. The electric draw stem is equipped with overload protector, which can avoid damage of motor. Program or remote handling can control the electric jaw valve. Reciprocating stroke can adjust position self-locking precisely. The electric hydraulic jaw valve adopts electric hydraulic draw stem and full hydraulic transmission. Thrust and pull can realize stepless velocity modulation. Pneumatic jaw valve adopts pneumatic draw stem and it can control remotely or in local equipped with fittings grouping. SEF denotes manual, DEF denotes electric, YEF denotes electric hydraulic and QEF denotes pneumatic driving.

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

•  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。

•  运行时请辨清扇形闸板开关方向，执行机构请正确接线。

•  运行时请定期给各传动部位加润滑油。

•  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.

•  Pay attention to the open-close direction of the gate when operate. The actuator must be wired exactly.

Add lubricant to the transmission parts regularly as it runs.
