Abstract

990,176. Valves. RHEINISCHES METALLWERK G.m.b.H. Sept. 25, 1961 [Sept. 24, 1960], No. 34277/61. Heading F2V. A non-return valve for preventing return flow in a pipe line comprises a flap 10 connected to and arranged to co-operate with the rim 12 of a cylinder 11, the valve being made of an elastomeric material and the external diameter of the cylinder arranged to correspond to the inner diameter of the pipe line. As shown in Fig. 4, the flap 10 is formed integrally with the cylinder 11 and provided with a reinforcing web 15, the cylinder being reinforced by a brass plate 16 embedded in the wall of the cylinder. Mounting flanges 13 are formed on the cylinder.
