Abstract
A device for controlling fluid flow includes a conduit that defines a channel through which fluid flows opposing upstream and downstream directions of fluid flow. A rupture valve obliquely disposed in the channel to selectively prevent fluid flow through the channel, the rupture valve resisting rupture in response to pressure exerted on the rupture valve in the upstream direction and selectively rupturing in response to pressure exerted on the rupture valve in the downstream direction.
Claims17
A device for controlling fluid flow, comprising:
- (a) a main conduit defining a channel having opposing upstream and downstream directions of fluid flow;
- (b) a rupture valve disposed in the channel to selectively prevent fluid flow through the channel, the rupture valve resisting rupture in response to pressure exerted on the rupture valve in the upstream direction and selectively rupturing in response to pressure exerted on the rupture valve in the downstream direction, the rupture valve extending obliquely between an upstream location and a downstream location of the channel;
- and
- (c) an ancillary conduit disposed downstream of the rupture valve and branching laterally from the main conduit, the ancillary conduit being in fluid communication with the channel at a location between the upstream location and the downstream location.

A device for controlling fluid flow, comprising:
- (a) a main conduit having opposing upstream and downstream directions of fluid flow;
- (b) a rupture valve disposed within the main conduit to selectively restrict fluid flow through the main conduit, the rupture valve extending between an upstream location and a downstream location, the rupture valve comprising:
- (i) a rupturable element;
- and
- (ii) a support element connected to the rupturable element such that the support element supports the rupturable element against rupture in response to pressure on the rupture valve exerted in an upstream direction and pivots with the rupturable element to permit fluid flow through the main conduit after the rupturable element ruptures selectively in response to pressure exerted in a downstream direction;
- and
- (c) an ancillary conduit disposed downstream of the rupture valve and branching laterally from the main conduit, the ancillary conduit being in fluid communication with the main conduit at a location between the upstream location and the downstream location.
