Analysis of the connection mode of electromagnetic pulse valve and pulse dust collector

The electromagnetic pulse valve is the actuator and key component of the pulse dust collector spraying and 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 the domestic pulse valve; the right-angle valve and the straight-through valve are 0.4 -0.6MPa; No matter which kind of valve is imported, the working pressure range is 0.4-0.6MPa, and the two types of valves have no difference in pressure and application pressure.

1) The technical parameters of the TMF-Y (DMF-Y) submerged electromagnetic pulse valve and the right-angle pulse valve are different: the pressure of the injection air source: 0.2-0.3MPa, 0.3-0.6MPa can also be used 3) the 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 in a straight line, so it is called a straight-through valve. The pulse valve diaphragm divides the pulse valve into two air chambers, the pulse valve is closed when the compressed air is connected. , The opening action principle is the same as 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 an air box pulse dust collector; the disadvantage is that the airflow through the valve body has a large resistance. The technical parameters of the TMF-T (DMF-T) straight-through electromagnetic pulse valve and the right-angle pulse valve are the same.

The principle of submerged pulse valve construction. The submerged pulse valve adopts the installation method of submerged in the air bag, so it is called the submerged type. Compared with other structural forms, it reduces the resistance of the flow channel and the pressure of the blowing air source, so it can be applied to low pressure occasions, and can reduce energy consumption and extend the life of the diaphragm.

2) The structure and working principle of the right-angle electromagnetic 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 inside the valve divides the pulse valve into two air chambers, the front and the rear. When compressed air is connected, the compressed air enters the rear air chamber through the orifice. At this time, the pressure of the air chamber closes the diaphragm to the output port of the valve. The pulse valve is closed. The electrical signal of the pulse controller makes the armature of the electromagnetic pulse valve move, the air chamber vent behind the valve opens, the vocal cord of the rear air chamber loses pressure, the diaphragm moves backward, the compressed air can be sprayed through the valve output port, and the pulse valve is in an open state. The compressed air is jetted out from the valve instantly, forming a jet of air flow. The technical parameters of TMF-Z (DMF-Z) right-angle electromagnetic pulse valve are as follows: Adapt to the environment: temperature -1055℃; relative humidity is not more than 85%.

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