Pulse valve used in dust collector

1) Right angle pulse valve construction and working principle. The right angle pulse valve is characterized by a 90 degree right angle of the valve inlet and outlet tubes. The diaphragm in the valve divides the 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 throttle hole, and the air chamber pressure closes the diaphragm to the output port of the valve. The pulse valve is off. The electric signal of the pulse controller makes the armature of the electromagnetic pulse valve move, the vent hole of the air chamber after the valve opens, the vocal cord of the rear air chamber loses pressure, the diaphragm moves backward, the compressed air can be blown through the valve output port, and the pulse valve is opened. The compressed air is instantaneously ejected from the valve to form a blowing air stream. TMF-Z (DMF-Z) right angle electromagnetic pulse valve technical parameters are as follows: adapt to the environment: temperature -1055 ° C; relative humidity is not more than 85%.

Working medium: clean air, dew point -20 °C. The pressure of the blowing air source is 0.3-0.6 MPa. Electromagnetic pilot valve operating voltage, current: DC24V, 0.8A; AC220V, 0.14A; AC110V, 0.3A pulse valve air inlet to the air bag, the air outlet is connected to the blow pipe. When connecting, the teflon raw tape should be used between the threads to ensure the seal. When connecting, be careful that the length of the intake end thread can not be greater than one third of the threaded wire.

2) Submerged pulse valve construction principle. The submerged pulse valve uses a mounting method that is submerged in the air bag, so it is called submerged. Compared with other structural forms, it reduces the flow path resistance and reduces the pressure of the blowing air source, so it can be used in the case of low pressure, and can reduce energy consumption and prolong the life of the diaphragm.

The technical parameters of the TMF-Y (DMF-Y) submerged electromagnetic pulse valve and the right angle pulse valve are different: the injection air source pressure: 0.2-0.3 MPa, 0.3-0.6 MPa 3) straight-through pulse valve can also be used. The structural characteristic of the straight-through pulse valve is that the air inlet and outlet center line is in a straight line, so it is called a straight-through valve. The pulse valve diaphragm divides the pulse valve into two front and rear air chambers. When the compressed air is turned on, the pulse valve is closed. The opening principle is the same as that of the right angle valve, except that the flow direction is different when the air is injected. The advantage of the straight-through pulse valve is that it is easy to install and is often used for a gas box pulse dust collector; the disadvantage is that the airflow passes through the valve body and has a large resistance. The TMF-T (DMF-T) straight-through electromagnetic pulse valve has the same technical parameters as the right-angle pulse valve.
