Submerged impulse valve submerged in gas package installation method, it said submerged. Compared with other structural forms, it reduces the resistance of the runner and reduces the pressure of the injection air source. Therefore, it can be applied to the occasion of depression and can reduce the energy consumption and prolong the service life of the diaphragm. The electrical signal of the pulse controller causes the armature of the electromagnetic pulse valve to move, the air vent of the air chamber of the rear valve is opened, the vocal cords of the air chamber are decompressed, the diaphragm is moved backward, the compressed air can be injected through the valve outlet, and the pulse valve is in an on state. Compressed air instantly spouts from the valve, forming a jet of air. TMF-Y (DMF-Y) submerged electromagnetic pulse valve and rectangular pulse valve technical parameters are different: Straight-through pulse valve. Straight-through pulse valve structure is characterized by air inlet and outlet centerline in a straight line, it said through the valve, pulse valve diaphragm to the pulse valve is divided into the front and rear two gas chambers, when the pulse of compressed air valve is turned off , Open the same action principle and right angle valve, but the jet flow when the flow of different directions. The advantages of straight-through pulse valve is easy to install, commonly used in gas box pulse dust collector; the disadvantage is the air flow through the body resistance larger. TMF-T (DMF-T) through the electromagnetic pulse valve and rectangular pulse valve with the same technical parameters. Impulse valve is a pulse jet cleaning device on the street agencies and key components, mainly sub-angle, submerged and straight through the three categories, it is noteworthy that the working pressure of domestic pulse valve; right angle and direct valve valve for the 0.4- 0.6MPa; no matter what kind of valve imported products, the working pressure range is 0.4-0.6MPa, two types of valves do not withstand the pressure and the difference between the level of pressure. Right angle pulse valve structure and working principle. Right-angle pulse valve is characterized by the valve inlet and outlet pipe 90 degrees at right angles. The diaphragm valve to the pulse valve is divided into the front and rear two gas chambers, when connected to compressed air, compressed air through the throttle into the back air chamber, then the gas chamber pressure diaphragm close to the output of the valve, Pulse valve is closed. Electromagnetic pulse valve used in the field of dust has been for many years, in order to enable the majority of dust removal workers to better understand the performance and principles of electromagnetic pulse valve, I hereby write this article, hoping to bring convenience to everyone. There are three types of commonly used pulse valve: right angle pulse valve, submerged pulse valve, and through pulse valve. The general theory of pulse valve: electromagnetic pulse valve is controlled by the electrical signal to open and close the valve unloading hole, the valve body unloading, the valve cavity after the pressure gas emissions, the valve cavity gas pressure on the diaphragm overcast Throttling orifice, the diaphragm is lifted, pulse valve for blowing. When the valve body stops unloading, the pressure gas rapidly fills the back chamber of the valve through the orifice. As the pressure area on the valve body is different on both sides of the diaphragm, the gas force is large in the back cavity of the valve, and the diaphragm can be reliably closed Valve blow port, pulse valve to stop blowing. The electrical signal is measured in milliseconds, the pulse valve is opened for a moment, resulting in a powerful impact airflow, so as to achieve instantaneous injection. The above is the basic theory of the pulse valve, but they vary with the type and some differences, the following I will be the basic theory of various pulse valve described below: First, the submerged pulse valve works: diaphragm electromagnetic pulse valve into the front, After the two air chambers, when the compressed air is connected, the compressed air enters the rear air chamber through the orifice, then the air chamber pressure will be close to the diaphragm assembly output valve, submerged pulse valve is closed. The electrical signal of the pulse injection controller makes the electromagnetic pulse valve armature move backward, the air vent of the air chamber of the valve is opened, the air chamber is rapidly decompressed, the diaphragm assembly is moved backward, the compressed air is injected through the valve outlet, the electromagnetic pulse valve is in Open state. Pulse electric pulse controller disappears, the electromagnetic pulse valve armature reset, after the gas chamber vent closed, after the gas chamber pressure so that the diaphragm assembly close to the valve output port, the electromagnetic pulse valve is closed. Electromagnetic pulse valve DSF-Z electromagnetic pulse valve) is a right angle pulse valve, the angle between the import and export of 90 degrees, it applies to the installation of gas cylinder and dust injection pipe installation, smooth flow, can provide the required pulse Clear air flow. Electromagnetic pulse valve is a pulse bag filter ash cleaning system compressed air switch. Controlled by pulse injection controller output signals, the filter bag by row (room) blowing cleaning, the resistance of the precipitator to keep within the set range, in order to ensure the capacity of the precipitator and dust collection efficiency. Second, the right-angle pulse valve works: TSF-Z (DSF-Z) -type electromagnetic pulse valve is a right angle valve, the angle between the import and export of 90 °, suitable for gas bag and dust collector injection pipe installation and connection. Smooth flow, can provide the required cleaning gas pulse. Diaphragm to the electromagnetic pulse valve is divided into the front and rear two gas chamber, when connected to the compressed air, the compressed air through the throttle into the back air chamber, then the gas chamber pressure diaphragm assembly close to the valve outlet, Electromagnetic pulse valve is closed. The electrical signal of the pulse injection controller makes the electromagnetic pulse valve armature move backward, the air vent of the air chamber of the valve is opened, the air chamber is rapidly decompressed, the diaphragm assembly is moved backward, the compressed air is injected through the valve outlet, the electromagnetic pulse valve is in Open state. Pulse electric pulse controller disappears, the electromagnetic pulse valve armature reset, after the gas chamber vent closed, after the gas chamber pressure so that the diaphragm assembly close to the valve output port, the electromagnetic pulse valve is closed. Electromagnetic pulse valve is a pulse bag filter ash cleaning system compressed air switch. Controlled by pulse injection controller output signals, the filter bag by row (room) blowing cleaning, the resistance of the precipitator to keep within the set range, in order to ensure the capacity of the precipitator and dust collection efficiency.
