A rupture control system for a conduit system for conducting fluid from a fluid source to a fluid receiver, the rupture control system comprising:
- a valve in fluid flow relationship with an inner conduit wherein the inner conduit is configured to be pressurizable by the fluid from the fluid source;
- wherein the inner conduit has an outer surface, an inlet in selective fluid communication with the fluid from the fluid source through the valve, and an outlet in fluid communication with the fluid receiver;
- an outer conduit configured pressurizable by the fluid from the fluid source, the outer conduit having an inner surface, a first end and a second end, the outer conduit sized and configured to receive an annular and longitudinal fluid conducting portion of the inner conduit therein;
- wherein the inlet of the inner conduit and first end of the outer conduit are attached sealably to the valve;
- wherein a containment/control passageway pressurizable by the fluid from the fluid source is defined between the outer surface of the inner conduit and the inner surface of the outer conduit, forming a fluid tight seal about the portion of the inner conduit received in the outer conduit;
- wherein the valve is attached between the fluid source and the inner conduit inlet and has a valve control comprising a biasing mechanism for moving the valve from an initial first position to a second position in response to a pressure in the containment/control passageway greater than a preset level;
- wherein the valve is configured to allow fluid communication between the fluid source and the inner conduit in the first initial position and to prevent fluid communication between the fluid source and the inner conduit in the second position;
- wherein the valve control comprises a valve control chamber in fluid communication with the containment/control passageway, a valve member unaffixed to the valve housing and received inside a bore of the valve housing, the bore being configured to allow linear movement of the valve member in a direction transverse to the direction of fluid flow from the fluid source to the inner conduit;
- wherein the valve member has an elongated portion linearly reciprocating in the bore and attached to a first side of an enlarged head portion, the enlarged head portion having a second side exposed to the valve control chamber and is supported by a valve stop in the first initial position;
- wherein the inner conduit outlet and the outer conduit second end are attached sealably to a connector, the connector comprising a means for allowing fluid communication between the inner conduit and the fluid receiver, the connector sized and configured to maintain ability of the inner conduit, the outer conduit, and the containment/control passageway to withstand fluid pressure of the fluid from the fluid source;
- wherein, upon rupture, at least some of the fluid from the fluid source flowing in the inner conduit flows through the rupture into the containment/control passageway and the valve control, whereby pressure of the fluid from the fluid source causes a response by the valve control to move the valve to the second position.
