Right Angle Electromagnetic Pulse Valve

Right-angle electromagnetic pulse valve is the compressed air ‘switch’ of pulse bag filter cleaning and blowing system.

Right-angle electromagnetic pulse valve is the pulse blowing cleaning device actuators and key components, mainly divided into right-angle type, submerged and through the three categories, electromagnetic pulse valve is a pulse bag filter cleaning and blowing system of compressed air ‘switch’. Controlled by the pulse valve blowing control instrument output signal, pulse valve one end of the compressed air package, the other end of the blowing tube, pulse valve back pressure chamber connected to the control valve, pulse control instrument control valve and pulse valve open. When the controller has no signal output, the control valve exhaust port is closed, the pulse valve nozzle at the closed state; when the controller sends out a signal to control the exhaust port is opened, the pulse valve back pressure chamber outside the gas drain pressure is reduced, the diaphragm produces a pressure difference between the two sides of the diaphragm due to the differential pressure effect of the displacement, the pulse valve is open, the compressed air from the packet of air through the pulse valve through the blowtorch small holes sprayed (from the blowtorch sprayed out of the gas). (the gas from the blowing tube is primary air). Pulse valve life: five years under the conditions of standard installation, correct use and reasonable maintenance.

Working Principle

The right-angle electromagnetic pulse valve is characterised by the air inlet and outlet pipes of the valve being at a right angle of 90 degrees. The diaphragm inside the valve divides the pulse valve into two chambers, the high pressure gas from the air inlet access, into the lower chamber, when the pulse valve is not powered, the gas through the upper and lower two shells of the constant pressure pipeline as well as one of the throttling holes into the decompression chamber, due to the spool in the spring under the action of the blocking of the pressure relief holes, the gas will not be discharged, so that the decompression chamber and the lower chamber of the pressure is the same, and the role of the spring, the diaphragm will be the blowing mouth blocked, gas The gas will not be flushed out. When the pulse valve is electrified, the valve core lifts up under the action of electromagnetic force, the pressure relief hole opens, and the gas is sprayed out. Due to the action of the constant pressure pipeline throttling holes, the outflow speed of the pressure relief hole is greater than the inflow speed of the gas in the pressure reducing room constant pressure pipeline, so that the pressure in the pressure reducing room is lower than that of the lower gas chamber, and the gas in the lower gas chamber lifts up the diaphragm and opens the blowing port, and the pressure in the decompression chamber is the same as that in the lower gas chamber.

Folding editorial paragraph structure characteristics

The valve body and valve cover of electromagnetic pulse valve are made of aluminium alloy die-casting, and have good performance after surface treatment. The diaphragm and sealing gasket are vulcanised and compounded by new technology. Electromagnetic pilot head is made of magnetic material and stainless steel isolation material, and the spring and fasteners are made of stainless steel. The receiver of the air distribution box (air bag) and the blowing pipe of the dust collector are inserted into the inlet and outlet of the valve respectively. And tighten the compression nut at the second end to seal. Can provide from 20, 25, 40S three specifications of the valve for a variety of different treatment (purification) air volume of the pulse bag filter selection. The valve body and valve cover are die-cast and covered with clear lacquer. The sealing gasket on the diaphragm adopts metal and rubber composite, with good rigidity and no leakage. Electromagnetic pilot head suction force, sensitive action. Valve opening performance is good, in the rated voltage 85% can open normally. The closing performance of the valve is good, it can be closed at 0.15Mpa air pressure.
