Type and working principle of electromagnetic pulse valve

The characteristic of the right Angle pulse valve is that the air inlet and outlet pipe of the valve is at a 90 degree right Angle. The diaphragm in the valve divides the pulse valve into the front and the back two air chambers. When the compressed air is connected, the compressed air enters the back air chamber through the throttle hole. At this time, the pressure of the back air chamber will be close to the output outlet of the valve, and the pulse valve is in the "closed" state.

The electrical signal of the pulse injection control instrument makes the electromagnetic pulse valve armature move, the air chamber release hole behind the valve opens, the air chamber quickly loses pressure, the diaphragm moves back, the compressed air can be sprayed through the valve outlet, and the pulse valve is in the "open" state. The compressed air is immediately expelled from the valve, forming a jet stream.

When the electrical signal of the pulse control instrument disappears, the armature of the pulse valve is reset, the vent hole of the rear air chamber is closed, and the pressure of the rear air chamber is raised to make the diaphragm close to the valve outlet, and the pulse valve is in the "closed" state.

Right Angle pulse valve technical parameters:

Working medium: Clean air, dew point -20 degrees Celsius.

Injection pressure: 0.3-0.8MPa.

Solenoid pilot valve operating voltage: DC24V, AC220V, AC110V.

Electromagnetic pulse valve is the actuator and key components of the dust cleaning device of the pulse bag dust collector, the main rectangular electromagnetic pulse valve, submerged electromagnetic pulse valve and straight-through electromagnetic pulse valve three categories, each class has 6 specifications from 20 ~ 76mm(0.75 ~ 3in).

The air consumption of each electromagnetic pulse valve is 30 ~ 600m3/min(0.2 ~ 0.6MPa). It is worth noting that the working pressure of the domestic pulse valve is 0.4 ~ 0.6MPa, and the submersible valve is 0.2 ~ 0.6MPa; No matter what kind of valve, the working pressure range is 0.06 ~ 0.86MPa, and the two types of valves do not bear the difference between the pressure and the application pressure.

① Construction and working principle of right-angle electromagnetic pulse valve

The right-angle electromagnetic pulse valve is characterized by a 90° right Angle for the air inlet and outlet pipe of the valve. The structure of the right Angle pulse valve is shown in the figure. As can be seen from the figure, the diaphragm in the valve divides the electromagnetic pulse valve into the front and back air chambers. When the compressed air is connected, the compressed air enters the back air chamber through the throttle hole. At this time, the pressure of the back air chamber will press the diaphragm close to the output outlet of the valve, and the pulse valve is in the "closed" state.

The electrical signal of the pulse injection control instrument makes the electromagnetic pulse valve armature move, the air chamber release hole behind the valve opens, the air chamber quickly loses pressure, the diaphragm moves back, the compressed air can be sprayed through the valve outlet, and the pulse valve is in the "open" state. The compressed air is immediately expelled from the valve, forming a jet stream.

When the electrical signal of the pulse control instrument disappears, the armature of the pulse valve is reset, the vent hole of the rear air chamber is closed, and the pressure of the rear air chamber is raised to make the diaphragm close to the valve outlet, and the pulse valve is in the "closed" state.

General electromagnetic pulse valve technical parameters are as follows.

a, adapt to the environment: temperature -10 ~ +55℃; The relative humidity is not more than 85%.

b, working medium: clean air, dew point -20℃.

c, injection air source pressure: 0.3 ~ 0.6MPa.

d, blowing volume: When the pressure of the injection air source is 0.6MPa, the injection time is 0.1s, and the outlet is emptied, Injection volume DMF-25 electromagnetic pulse valve injection volume 45(L/ time), DMF-40 electromagnetic pulse valve injection volume 70(L/ time), DMF-50 electromagnetic pulse valve injection volume 160(L/ time), DMF-62 electromagnetic pulse valve injection volume 270(L/ time).

e, electromagnetic pilot valve operating voltage, current: DC24V, 0.8A; AC220V, 0.14A; AC110V, 0.3A.

f, electromagnetic pulse valve inlet air bag, the air outlet is connected with the spray pipe. When side joint, the thread should be filled with PTFE raw material tape to ensure sealing. When connecting, it should also be noted that the length of the screw screw in the intake end should not be too large, so as not to affect the injection volume.
