The right angle electromagnetic pulse valve is the compressed air "switch" of the pulse bag filter dust cleaning and spraying system. Its outlet and inlet form a 90 degree angle, so it is called a right angle electromagnetic pulse valve. Under the control of the output signal of the pulse blowing control instrument, it sprays and cleans the filter bag row by row (chamber) to maintain the pressure of the dust collector within the set range, ensuring the processing capacity and dust removal efficiency of the dust collector.

The characteristic of a right angle electromagnetic pulse valve is that the air inlet and outlet pipes of the valve are at a 90 degree right angle. The diaphragm inside the valve divides the pulse valve into two chambers, front and rear. High pressure gas is introduced from the inlet and enters the lower chamber. When the pulse valve is not powered, the gas enters the pressure reducing chamber through the constant pressure pipeline of the upper and lower shells and the throttle hole. Due to the valve core blocking the pressure relief hole under the action of the spring, the gas will not be discharged, making the pressure in the pressure reducing chamber and the lower chamber consistent. Under the action of the spring, the diaphragm blocks the blowing port, and the gas will not rush out. When the pulse valve is powered on, the valve core lifts upward under the action of electromagnetic force, the pressure relief hole opens, and gas is sprayed out. Due to the effect of the constant pressure pipeline orifice, the outflow velocity of the pressure relief hole is greater than the inflow velocity of the constant pressure pipeline gas in the pressure reducing chamber, causing the pressure in the pressure reducing chamber to be lower than that in the lower chamber. The gas in the lower chamber lifts the diaphragm and opens the nozzle.

Structural characteristics

The right angle electromagnetic pulse valve body and valve cover are made of aluminum alloy die-casting and have good performance after surface treatment. The membrane and sealing gasket are vulcanized and compounded using a new process. The electromagnetic pilot head is composed of magnetic materials and stainless steel magnetic isolation materials, and the spring and fasteners are made of stainless steel materials. The connecting pipe of the air distribution box (air bag) and the spray pipe of the dust collector are respectively inserted into the inlet and outlet of the valve. And tighten the two end compression nuts for sealing. We can provide valves in three specifications of 20, 25, and 40S for various pulse bag filters with different processing (purification) air volumes to choose from. The valve body and valve cover are densely die cast and covered with transparent paint on the surface to improve performance. The sealing gasket on the membrane is made of metal and rubber composite, with good rigidity and no leakage. The electromagnetic pilot head has a strong suction force and operates sensitively and reliably. The valve has good opening performance and can open normally at 85% of the rated voltage. The valve has good closing performance and can reliably close at a pressure of 0.15Mpa.
