QUIET PULSE VALVE

摘要

A relatively quiet pulse valve and a method of using the pulse valve are provided. The pulse valve includes a dampening mechanism to decrease mechanical stresses, decrease operating noise, decrease compressed air waste and increase operational life expectancy of the valve. Such dampening mechanism is arranged within an internal area of the pulse valve housing.

主权项

1. A valve device useful for pulsed compressed air cleaning of a filter unit comprising:
a housing with a plunge slideably positioned therein arranged in an opening of a pressure vessel containing compressed air; a plurality of openings in the housing for the flow of compressed air from the pressure vessel through the housing to a nozzle pipe useful for cleaning at least a portion of a filter unit when the plunge is in an open position; and a fluid supply on the housing for control of a fluid to a cavity within the housing to cause movement of the plunge to a closed position for blocking the plurality of openings and blocking the flow of compressed air from the pressure vessel to the nozzle pipe.
