摘要：An air supply system and valve is disclosed which provides a reverse pulse of airfor cleaning a filter element located in a filter house. A valve is also disclosed for use inthe air supply system. The system includes a pressure vessel adapted to contain avolume of compressed air to be used for supplying the reverse pulse, the pressure
vessel having a wall with at least one outlet aperture therein. The valve is mounted to thewall around the aperture to control the flow of air from the pressure vessel, the valvemeans comprising a valve body having an inlet, an outlet and a flow passage connectingthe inlet and outlet, the inlet, the outlet and the flow passage generally extending axiallythrough the valve body, a valve seat surrounding the flow passage, and a valve closuremember movable towards and away from the valve seat into closed and open positionsto thereby close or open the flow passage, and operating means for moving the valveclosure member between the closed and open positions. A conduit mounted to the valvebody around the outlet and adapted to extend into the filter house in use so as to directa pulse of air towards a filter element to be cleaned when the valve closure member is inthe open position.
