Abstract

1285534 Valves A D SANDS 4 Feb 1971 3891/71 Heading F2V A safety cutoff valve closed by rush of fluid in the event of a sudden loss of downstream pressure, e.g. in cutting torches or hydraulic systems, has a housing 10 with coaxial inlet and outlet ports 23, 24. A valve member V shaped as a body of revolution has reduced diameter portions 32, 33 on opposite sides forming locations for springs. The other ends of the springs are located on shoulders 29, 30 inside the ports. As shown, the valve member is of double seating conical form for co-operation with opposed seats 25, 26, and has conical ends 36 to give an approximately streamlined form. The springs may constitute a sole support of the valve member, or in other embodiments, additional support from guide stems is provided. The stems may be guided in ring guides formed at end coils of the springs, or by spider inserts, Figs. 10 and 21 (not shown). The valve member may also be single-seating. By-pass valves 50, 51 of needle screw type enable the pressures to be equalized for resetting. These may, be provided with keeper screws (95), Fig. 18 (not shown). Other modifications include sealing rings on the valve member and a hollow through-stem which allows a constant small flow in systems where this is permissible and desired.
