Abstract
743,346. Valves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 1, 1954 [April 1, 1953], No. 9111/53. Class 135. A non-return valve comprises a spring - loaded closure member 16 of tubular form coacting with a resilient seat 15 and controlling ports 26 in a fixed guide element 24 which also serves as a stop to limit the degree of engagement of the closure member with the resilient seat. The latter, which is held in position by a sleeve 18, is exposed to and deformed by the fluid pressure that closes the valve so as to provide an efficient seal against the closure member. The closure member is moved beyond the ports 26 to open the valve either by fluid pressure applied to the inlet 13 or by mechanical operation of a stem 29, e.g. by a gauging device screwed on to the end 13 for measuring the pressure in a container to which the valve may be fitted.
