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.
