Abstract

995,929. Valves. RHEINISCHE METALLWERK G.m.b.H. Oct. 31, 1962 [Nov. 11, 1961; Feb. 17, 1962], No. 41174/62. Heading F2V. A check valve has a movable closure member 11, Fig. 1, encased in an elastomeric material 12, e.g. rubber, which is integral with a bellows 14, the upper end of which is clamped to the valve casing; the bellows acts to load the closure member. The member 11 incorporates a stem 15 slidable in a hollow spindle 20 threaded into the casing and by which the valve may be volitionally closed. The lower part 5 of the material 12 may be grooved to form a sealing lip, and the convolutions of the bellows may be helical. The chambers above the closure member may be sealed so that the air in the chamber is compressed and exerts an additional closing force on the closure member as the latter lifts. In a modification, the closure member 11, Fig. 6, is arranged at an angle to the flow passage and a freely slidable sleeve 42 is disposed around the stem 15 to prevent the fluid in chamber 43 forcing the bellows 14 into contact with the stem 16; the sleeve 42 and stem 15 are made from a rust resistant material, or a synthetic plastic. In a further modification, the top of the closure member is provided with tongues which engage in body grooves to guide the closure member; these tongues also prevent the closure member from being urged too tightly on to its seat.
