Abstract

537,334. Non-return valves. K.TELL, H. Sept. 8, 1939, No. 25440. [Class 135] A non-return valve for water pumps has a compressible looseball valve member of such dimensions relative to its seat that the valve member may be forced through the seat aperture by a pressure less than that likely to rupture the piping. The ball may have an iron or gun-metal case and the seat may have a projecting sharp edge a. The usual strainer box or a constriction in the pipe below the valve prevents loss of the ball.
