Valve for dust collector

摘要

A valve for a dust collector comprises a bonnet (32) and a valve body (28) formed with a fluid port (26) for introducing a pressure fluid filled in a pressure vessel (14); a diaphragm (22) provided displaceably in accordance with an action of the pressure fluid introduced into a diaphragm chamber (34), for opening/closing a passage for making communication between the fluid port (26) and a main dust collector body (12); and a disk member (42) provided displaceably integrally with the diaphragm (22) to shield the diaphragm (22) so that it serves as a pressure-receiving surface for the pressure fluid when the pressure fluid is supplied to the main dust collector body (12).
