Pulse jet valve

1. Used outside of bag-type duster sack-duster’s blowing and cleaning ash.
2. Adopte this kind of structure that submerge in the air porket.
3. Compare to other structure, reduce resistance in interval channel and pressure of blowing supplier.
4. So it adapt siuation of low pressure, reduce energy consumption and prolong membrance patch using.

Produce Structure
Tract: Valve’s crust and close over is made of aluminum alloy that’s formed by pressing die, good appearance, heavy intensity, no gas leak. Structure of connection of two back pressing air of interval channel of valve is reasonable. this design make “ubmerged-type” true due to opening and closing face of valve locate in air pocket. Air from pocket can come in blowing cannulation straightly. It accord request with low air pressure and big quantity of blowing.
Electromagnetically operated valve: Control pulse valve by remoting. With trube base coil and DIN electrical outlet, conwiniet inner setting or outer setting, waterproof and dustproof for protect. Upto JB/t5916-91 standard.
Membrane patch: Adopt dish-type, and big moving. Valve can be opened in 0.08-0.1 second. You can choice synthetic rubber membrane patch made of import materials in frigid climate. Membrane patch can be longest used when working temperature is from -40℃ to -55℃.

 Technical Paremeter
Acclimation:
1) Temperature: -10~+55℃;
2) Working Medium: clean air
2Humidity: less than 85%
3Blowing Supplier Pressure: it’s better 0.2~0.3Mpa,or0.3~0.6Mpa.
4Blowing Tolerance: when blowing supplier pressure is 0.25Mpa and blowing time is 0.1 second.
