Description

Technical Field

[0001] The utility model relates to the field of pulse valves, in particular to a bag dust collecting pulse valve insulation device. Background Art

[0002] The pulse valve is mainly installed in the pulse dust collector. The diaphragm divides the electromagnetic pulse valve into two air chambers, the front and rear. When it is connected, the compressed air enters the rear air chamber through the throttle hole. At this time, the pressure of the rear air chamber makes the diaphragm close to the valve output port, and the electromagnetic pulse valve is in the "closed" state. The electrical signal of the pulse jet controller disappears, the electromagnetic pulse valve armature resets, the rear air chamber vent hole is closed, and the rear air chamber pressure increases, making the diaphragm close to the valve outlet, and the electromagnetic pulse valve is in the "closed" state again.

[0003] Most of the existing pulse valves are installed in pulse dust collectors. When encountering low-temperature outdoor dust removal conditions, such as when the ambient temperature is below zero degrees Celsius, the compressed air with moisture is easy to freeze when passing through the pulse valve, causing serious air leakage in the pulse valve, which is not conducive to subsequent dust removal.

[0004] Therefore, the utility model provides a bag dust collection pulse valve insulation device to solve the above problems. Utility Model Content
