Cloth bag dust collector pulse valve

Details
The type and function of pulse valve for bag filter is the actuator and key components of pulse ash cleaning device. It is mainly divided into three types: right-angle type, submerged type and straight-through type. Each type has 6 specifications. ~ 3in). Air consumption for each injection of 30 ~ 600m3

/ min (0.2 to 0.6 MPa). It is worth noting that the working pressure of domestic pulse valve is right angle valve and direct valve is 0.4 ~ 0.6MPa, submerged valve is 0.2 ~ 0.6MPa; no matter which kind of valve of imported products, the working pressure range is 0.06 ~ 0.86MPa, two The type of valve does not distinguish between the pressure and the application pressure.

① Structure and working principle of right-angle pulse valve

The right angle pulse valve is characterized by a 90 ° right angle of the air inlet and outlet pipes 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 inside the valve divides the electromagnetic pulse valve into two front and rear air chambers. When the compressed air is turned on, the compressed air enters the rear air chamber through the orifice. The output of the valve is attached, and the pulse valve is in the "closed" state. The electric signal of the pulse injection controller causes the solenoid pulse valve armature to move, the vent hole of the air chamber behind the valve opens, the back chamber quickly loses pressure, the diaphragm moves backward, and compressed air can be injected through the valve output port. "status. Compressed air is instantly ejected from the valve, forming a blowing air flow.

When the electrical signal of the pulse controller 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.

The technical parameters of our factory electromagnetic pulse valve are as follows.

a, adapt to the environment: temperature -10 ~ +55 ℃; relative humidity is not greater than 85%. b. Working medium: clean air, dew point -20 ℃. c. Injecting air source pressure: 0.3 ~ 0.6MPa.

d.Blowing air volume: When the pressure of the blowing air source is 0.6MPa, the blowing time is 0.1s, and when the outlet is empty,
e. Working voltage and current of electromagnetic pilot valve: DC24V, 0.8A; AC220V, 0.14A; AC110V, 0.3A.

f. The air inlet of the pulse valve is connected to the air bag, and the air outlet is connected to the blowing pipe. For edge connection, the thread shall be filled with Teflon raw tape to ensure the seal. When connecting, please also pay attention that the length of the screw-in of the inlet end should not be too large, so as not to affect the injection air volume. ② Working principle of submerged pulse valve structure The submerged pulse valve adopts the installation method of being submerged in the air bag, so it is called submerged type. The structure of the submerged pulse valve is shown in the figure. Compared with other structural forms, it reduces the resistance of the flow channel and the pressure of the injection gas source. Therefore, it can be used in low pressure situations, and can reduce energy consumption and prolong the life of the diaphragm. .

The working principle of the submerged pulse valve is that the diaphragm makes the pulse valve into two front and rear chambers. When the compressed air is connected,

Compressed air enters the rear air chamber through the orifice. At this time, the pressure of the rear air chamber will bring the diaphragm close to the output of the valve, and the pulse valve is in the "closed" state.

When the electrical signal of the pulse controller moves the pulse valve armature, the vent hole of the air chamber behind the valve opens, the back air chamber quickly loses pressure, the diaphragm moves, compressed air is blown through the valve output port, and the pulse valve is in the "open" state. At this moment, a stream of compressed air is ejected.

The electrical signal of the pulse controller disappears, the armature of the pulse valve is reset, the air 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.
