的特征是阀的空气进出口管成90度直角，阀内的膜片把 脉冲电磁阀DMF-Z-20A分成前、后两个气室，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贴阀的输出口，脉冲阀处于“关闭”状态。 The pulse solenoid valve DMF-Z-20A is characterized in that the air inlet and outlet pipes of the valve are at a right angle of 90 degrees. The diaphragm inside the valve divides the pulse solenoid valve DMF-Z-20A into two front and rear air chambers. When compressed air is turned on, At this time, compressed air enters the rear air chamber through the orifice. At this time, the pressure of the rear air chamber presses the diaphragm against the output port of the valve, and the pulse valve is in the "closed" state.
输出喷吹，脉冲阀处于“开启”状态，压缩空气瞬间从阀内喷出，形成喷吹气流。 The electric signal of the pulse controller makes the solenoid pulse valve armature move, the vent hole of the air chamber behind the valve is opened, the back air chamber is quickly relieved of pressure, and the diaphragm is moved backward. In the "open" state, compressed air is instantly ejected from the valve, forming a blowing air flow.
When the electric signal of the pulse controller disappears, the armature of the pulse valve is reset, the pressure relief hole of the rear air chamber is closed, the pressure of the rear air chamber is increased, the diaphragm is close to the valve outlet, and the pulse valve is in the "closed" state.
