Pulse jet valves are used in filtering systems of dust collectors, gas turbines, and desulfurization equipment. They are commonly used to clean filters such as cartridge filters, envelope filters, ceramic filters, and sintered metal fiber filters. Here, we discuss how these valves work in a typical application for dust collector systems.
Working principle of right-angle pulse valve
Under the high pressure gas from the air inlet access into the chamber,
- When the pulse jet valve without electricity, the constant pressure of the gas through the upper and lower shell pipelines and the orifice into the decompression chamber, because under the action of spring block pressure relief valve core hole, the gas will not discharge, the vacuum chamber and the gas chamber pressure, and under the effect of spring, the diaphragm will be blowing mouth plug, the gas does not rush out.
- When pulse valve, valve core under the effect of electromagnetic force is raised up, the pressure relief hole is opened, gas jet, due to the effect of constant pressure pipe orifice, flow speed is greater than the pressure relief hole decompression chamber constant pressure pipe gas flow rate, the decompression chamber pressure is lower than the air chamber pressure, gas chamber under the diaphragm jacking, open the mouth blowing, gas injection.
Working principle of submerged pulse valve
The structure and the right Angle pulse valve are basically the same, but without the air inlet, directly using the gas bag as its lower gas chamber, its principle is the same.
