Factory direct supply pulse valve MK-50, MK-62, MK-76, VP-20, VP-25, VP-40

Pulse valve is the execution mechanism and key component of pulse jet cleaning device. It is mainly divided into three types: right-angle type, submerged type and straight-through type. It is worth noting that the working pressure of domestic pulse valve; right-angle valve and straight-through valve are 0.4- 0.6MPa; no matter which type of valve is imported, the working pressure range is 0.4-0.6MPa. There is no difference between the pressure and the application pressure of the two types of valves.

 

1) Structure and working principle of right-angle pulse valve. The characteristic of the right-angle pulse valve is that the air inlet and outlet pipes of the valve are at a right angle of 90 degrees. The diaphragm in the valve divides the pulse valve into two air chambers, the front and the rear. When the compressed air is connected, the compressed air enters the rear air chamber through the orifice. At this time, the pressure of the air chamber will make the diaphragm close to the output port of the valve. The pulse valve is closed. The electric signal of the pulse controller makes the armature of the electromagnetic pulse valve move, the vent hole of the air chamber behind the valve is opened, the vocal cord of the rear air chamber loses pressure, the diaphragm moves back, the compressed air can be sprayed through the valve output port, and the pulse valve is in the open state. Compressed air is instantly ejected from the valve to form a jet airflow. The technical parameters of TMF-Z (DMF-Z) right-angle electromagnetic pulse valve are as follows: Adapt to the environment: temperature -1055 ℃; relative humidity not greater than 85%.

 

Working medium: clean air, dew point -20℃. Blowing air source pressure: 0.3-0.6MPa. Working voltage and current of electromagnetic pilot valve: DC24V, 0.8A; AC220V, 0.14A; AC110V, 0.3A The air inlet of the pulse valve is connected to the air bag, and the air outlet is connected to the blowing pipe. When connecting, tetrafluoroethylene raw material tape should be used between the threads to ensure sealing. When connecting, it should be noted that the length of the incoming thread at the intake end should not be greater than one-third of the thread connecting wire.

 

2) Construction principle of submerged pulse valve. The submerged pulse valve adopts the installation method of being submerged in the air bag, so it is called submerged type. Compared with other structural forms, it reduces the resistance of the flow passage and the pressure of the blowing air source, so it can be suitable for low pressure occasions, and can reduce energy consumption and prolong the life of the diaphragm.

 

The technical parameters of the submerged electromagnetic pulse valve and the right-angle pulse valve are different: the pressure of the injection gas source: 0.2-0.3MPa, or 0.3-0.6MPa3) straight-through pulse valve. The structural feature of the straight-through pulse valve is that the center line of the air inlet and outlet is on a straight line, so it is called a straight-through valve. The pulse valve diaphragm divides the pulse valve into two air chambers, the front and the rear. When the compressed air is connected, the pulse valve is in a closed state. , the opening action principle is the same as that of the right-angle valve, but the flow direction of the air jet is different. The advantage of the straight-through pulse valve is that it is easy to install, and it is often used in the air box pulse dust collector; the disadvantage is that the airflow through the valve body has a large resistance. The straight-through electromagnetic pulse valve has the same technical parameters as the right-angle pulse valve.
