The electromagnetic pulse valve is the "air switch" of the injection air path of the pulse bag dust removal system. The key to the normal operation of the diaphragm in the valve body is. The diaphragm of the pulse valve includes a rivet head to block the compressed air pipeline or the air outlet of the valve, a vent hole for unloading, and bolt holes for fixing and supporting around. The diaphragm divides the valve body into two front and rear air chambers. The area of the back control is larger than the area of the front control, and the pressure is large.
The electromagnetic pulse valve diaphragm divides the pulse valve into two air chambers. When the electromagnetic pulse valve is connected to the clean compressed air in the pulse bag dust removal system, the compressed air passes through the orifice and enters the rear air chamber. At that time, the pressure of the back air chamber will bring the diaphragm close to the valve's air outlet. The pulse valve is closed. The pulse controller outputs a signal to move the pulse valve armature. The air vent hole of the back air valve opens and the back air chamber loses pressure quickly, The diaphragm moves backward, compressed air is blown through the valve's air outlet, the pulse valve is opened, and the blowing starts. The electrical signal output by the pulse controller disappears, the electromagnetic pilot armature of the pulse valve resets, and the rear air chamber vent hole is closed. The increase of the pressure in the air chamber makes the diaphragm of the pulse valve close to the outlet of the valve, the pulse valve is closed, the injection is stopped, and the length of the injection time is controlled by the controller.
Based on the previous production experience of solenoid valve diaphragms, it has absorbed and summarized the advantages of similar products at home and abroad and the production process advantages. It has newly developed improved solenoid valve diaphragms and pulse valve diaphragms. The production of the rubber sheet of the valve diaphragm has the characteristics of strong oil resistance, acid resistance, high temperature resistance, alkali resistance, etc., which can easily ensure the synchronous operation with other control components and control the injection of pulsed compressed air. Even in extremely harsh working conditions, it can guarantee its normal work and long service life. The diaphragm has an operating life of not less than 1 million times at an ambient temperature of -20-80 ° C and an operating pressure difference of 0.8 MPa.
