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.
Claims20
A device for controlling fluid flow, comprising:
- (a) a conduit defining a channel having opposing upstream and downstream directions of fluid flow;
- and
- (b) 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.
A device for controlling fluid flow, comprising:
- (a) a conduit having opposing upstream and downstream directions of fluid flow;
- and
- (b) a rupture valve disposed within the conduit to selectively restricting fluid flow through the conduit, 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 channel after the rupturable element ruptures selectively in response to pressure exerted in a downstream direction.
