The Working Principle Of Electromagnetic Pulse Valve Do You Know?
The working principle of the electromagnetic pulse valve is to use the pulse of the electrical device to convert it into the mechanical pulse so that the powerful energy of the pulsed gas becomes momentum to release a huge impulse in a short time. The interval of the pulse controlled by the plc should be determined according to the recovery time of the rated gas pressure.
There are closed chambers in the electromagnetic pulse valve. There are through holes in different positions. Each hole leads to a different oil pipe. The middle of the cavity is the valve of the point pulse valve. The two sides are two electromagnets. Which side of the magnet coil is energized. Which side the valve body will be attracted to. When the coil is energized instantaneously, the electromagnetic force moves the armature. When the coil is de-energized, the armature is retained by the permanent magnet force.
At this time, the upper medium pressure of the diaphragm in the main valve chamber passes through the pressure-relief hole, so that the pressure is formed on the diaphragm. Poor, under the influence of the pressure of the inlet media, lift the diaphragm and the main valve opens. When an instantaneous reverse current is applied to the coil, the armature moves in the opposite direction and the pressure relief hole is cut off. The medium enters the upper part of the diaphragm through the main valve balancing hole and seals the main valve port.
The above is the general principle of the electromagnetic pulse valve, but in fact, according to the temperature, pressure, etc. flowing through the medium, the working principle of the electromagnetic pulse valve is different. For example, in the free-flow state, if zero pressure is needed to start, the coil will suck up the brake body when it is energized; when there is the electromagnetic pulse valve in the state of pressure, it is a pin that is inserted on the brake body after the coil is energized. Use the pressure of the fluid itself to lift the lock.
The difference between these two methods is that the self-flow state electromagnetic pulse valve, because the coil to suck up the entire gate, so the larger and pressure state of the electromagnetic pulse valve, only need to suck up the pin, so the volume can be done It's relatively small.
