Abstract
549,517. Actuating-diaphragms. GROVE, M. H. April 29, 1941, No. 5562. [Class 135] An actuating diaphragm, particularly adapted for use in pressure regulators, is clamped between two sheet metal parts one 24 having a flange of greater diameter than the diameter of the diaphragm and provided with a rim 28, the other of less diameter than the inner diameter of the rim, by a member 44 engaging the rim and the second named part. In the form shown in the Figures the member 24 is corrugated and welded to a central steel tube 23. The member 26 is dome-shaped to provide a gaseous loading chamber 22 filled through a needle valve 88 and is closed by a plate 34 welded in place and provided with a small central orifice 36 and curved to correspond with the shape of the diaphragm. Two other sheet metal parts, a flanged conical part 46 with parts 54, 56 and a flanged dome-shaped part 48 are welded to the tube 23 to provide a fluid chamber connected to the tube 23 by ports 57. The flanges of the members 24, 46 are integrally bonded together and to the flange 27. All the flanges and the flange 62 on a member provided with louvres 61 for aiding the dissipation of heat are clamped between two annular rings 44, 63 by bolts 43 passing through the annular area between the rim 28 and the periphery of the members 26. A curved plate resting on the diaphragm 19 has an abutment 72 welded to it engaging the lower end of the valve rod 64 passing through bushings 66, 67 at the upper and lower ends of the tube 23 into the valve casing. The valve spindle carries a valve head 16 adapted to co-operate with a seat held in place by a cage 76 pressed down by a pair of Belleville washers 86 bearing against closure 82 secured in place by a screwed ring 83. A deflector 73 is fitted to the valve spindle immediately above the coned upper end of the bushing 66. Specification 447,519 is referred to.
