US Patent:

41162099, Sep 26, 1978

Filed:

May 5, 1977

Appl. No.:

5/794264

Inventors:

Charles W. Greer - Beverly Hills CA

International Classification:

F16K 1736

US Classification:

137 38

Abstract:

A shock actuated shut-off valve for fluid flow lines is provided which includes a valve housing having a central chamber in communication with (a) a hollow inlet conduit, (b) a hollow outlet conduit and (c) a hollow, outwardly enclosed stowage arm in upward, substantially plumb communication with the central chamber. A valve element is disposed in the stowage arm in spaced relationship to the inner wall thereof and is releasably supported therein by a support member secured to the inner wall. Vibratory force effects displacement of the valve element from the support member and transition of the same into the central chamber where the valve element sealingly engages the chamber to interrupt the fluid flow passage from the inlet conduit to the outlet conduit.

International Classification:

F16K 1736

US Classification:

137 38

Abstract:

An air actuated valve system for shutting off fluid flow in a fluid conduit includes a seismic valve disposed in a seismic air circuit which is coupled to a primary air circuit. The primary air circuit delivers air at a high pressure to an air driven actuator which maintains a shut off valve in a fluid conduit in an open position. The high air pressure flows through an air switch which is operationally open and coupled to the seismic air circuit such that when the seismic valve is closed a pilot air pressure is prevented from flowing to the air switch. In the absence of the pilot air pressure, air pressure is bled from the air switch, causing the air switch to move from an open to a closed position, thus preventing air from flowing to the air actuator.

International Classification:

F16K 1736

US Classification:

137 38

Abstract:

A shock actuated shut-off valve for fluid flow lines is provided which includes a valve housing having a central chamber in communication with inlet and outlet conduits and with a hollow, outwardly enclosed stowage arm in upward, substantially plumb communication with the central chamber. A valve element having a longitudinal aperture incorporating non-occlusive abutment means is releasably supported in the stowage arm for vibratory displacement to and sealing engagement with the central chamber. An inner closure is sealingly disposed in the stowage arm above the valve element. A tether slidably and sealingly extends through an aperture in the inner closure and extends, in spaced relationship, through the aperture in the releasably supported valve element, with the lower end of the tether incorporating a lift member disposed, in a non-obstructive static position, below the abutment means. Following displacement of the valve element to the central chamber, reset is effected by the sequential application of upward and downward force to the tether whereby the valve element, upon being engaged by the lift member, is lifted upwardly to a stop position and thereafter descends to its releasably supported position with the lift member descending to its static position.
