DMF-Y-76S电磁脉冲阀(淹没式)
一、 用途：Usage
电磁脉冲阀（亦称隔膜阀）是脉冲袋式除尘器清灰喷吹系统的压缩空气“开关”。
受脉冲喷吹控制仪输出信号的控制，对滤袋逐排（室）喷吹清灰，使除尘器的阻力保持在设定的范围之内，以保证除尘器的处理能力和收尘效率。
Electro-magnetic valve(also called diaphragm valve) is the “switch”for compressed air in the dust clean blowing system of the pulse bag filter.Controlled by the output signals of the pulse jet control device,it makes dust clean to the filter bags cell by cell to keep the resistance of the baghouse within the set range and thus guarantee the processing functions and the dust-collecting efficiency of the baghouse.
DMF-Y型电磁脉冲阀为淹没式阀，（亦称嵌入式阀）它直接安装在气包上，具有更好的流通特性。
压力损失有所下降，适合气源压力较低的工作场合。
DMF electro-magnetic pulse valves are embedded valves(also called submerged ones)which are directly installed on the header.They have better flow characterisics and operate with reduced pressure loss,therefore they are suitable for conditions where the pressure of the gas source is relatively low.

三、 工作原理：Working Principle
膜片把电磁脉冲阀分成前、后二个气室，当接通压缩空气时，压缩空气通过节流孔进入后气室，此时后气室压力将膜片紧帖阀的输出口，电磁脉冲阀处于“关闭”状态。
The electro-magnetic pulse diaphragm valve is composed of two gas cells.When the compressed air is connected,it comes into the back gas cell though the orifice,THhe pressure in the back gas cell pushes the diaphragm closely against the outlet of the valve and the electro-magnetic valve stays in the “closed ”condition.
脉冲喷吹控制仪的电信号使电磁脉冲阀衔铁移动，阀后气室放气孔打开，后气室迅速失压，膜片后移，压缩空气通过阀输出口喷吹，电磁脉冲阀处于“开启”状态。
The electrical signals from the pulse jet control device move the armature of the electro-magnetic pulse valve.The air escape of the back gas cell opens and the back gas cell loses pressure quickly,thus the diaphragm moues bakd and the compressed air blows through the valve outlet.The electro-magnetic pulse valve comes into the “open”condition.
脉冲喷吹控制仪电信号消失，电磁脉冲阀衔铁得位，后气室放气孔关闭，后气室压力升高使膜片紧帖阀的输出口，电磁脉冲阀又处于“关闭”状态。
When the electrical signals from the pulse jet control device disappear,the armature of the elecrto-magnetic pulse valve retums to its original position.The air escape of the back gas cell closes and the pressure in the back gas cell riese,which pushes the diaphragm closely against the valve outlet.The electro-magnetic valve comes into its “closed ”condition again.
