Abstract:
A shear valve for use in a downhole tool between the annulus and tubing in a well comprises an outer housing and an internal body movable in a longitudinal direction within the housing when the valve is activated, and at least one obstruction device which can be arranged to obstruct the internal body from moving. The obstruction device is capable of being deactivated by pressure from the tubing side of the valve.

Abstract:
A cartridge assembly for a valve is disclosed. The cartridge assembly (230) includes a cartridge containing an activation component. The cartridge (210) and activation component (216) are configured to be replaceable as a unit. The activation component prevents the valve from either opening or closing until either a predetermined pressure is exerted on the valve or a predetermined temperature is experienced by the activation component. The cartridge may include any of a variety of activation component types, such as buckling pins, tensile pins, shear pins, springs, or fusible alloys, either individually or in combination to control the valve opening or closing.
Abstract:
A fluid conduit safety system which comprises valves (44) at each end of the conduit (20) which are connected by a cable (58). If the hose (20) ruptures, the valves (44) close preventing discharge of fluid from the fluid supply and discharge of fluid from the container being filled while at the same time the cable (58) prevents the ends of the hose from whipping about and causing damage or injury. Another aspect of the invention relates to a method for stopping the flow of fluid through a conduit (20) which fails, which comprises the steps of providing a conduit (20) with a valve (44) at each end and means (58) connecting the valves to each other and disposed in the conduit.
Abstract:
The present invention relates to devices, systems, and methods for a safety interlock for a gas cylinder. The interlock device of the present invention can prevent a gas cylinder from being removed from a gas administration device as long as gas remains in the gas cylinder.
Abstract:
Rohrabsperreinrichtung (10) umfassend einen in einer Rohrleitung (3) angeordneten Rohrabschnitt (10a) mit einem Absperrglied (19), wobei das Absperrglied (19) in Schließstellung durch eine im Bereich des Rohrabschnitts (10a) angeordnete Einrichtung (22) zerstörbar ist, wobei die (10) Einrichtung zur Zerstörung des Absperrgliedes (19) von außen betätigbar ist.
Abstract:
A stress reactive valve includes a valve body disposed in a subsea safety system or other elongated components of hydrocarbon production systems. The valve body includes a frangible or breakable material such that when the subsea safety system or other elongated system undergoes a stress, such as a bending stress, the frangible valve body can react to the stress by breaking and thereby establishing fluid communication or a fluid path across the valve body. In a first or unbroken condition of the valve body, the valve body prevents fluid communication between a fluid inlet and a fluid outlet. In a second or broken condition of the valve body, fluid communication is allowed between the fluid inlet and outlet. The fluid communication can be used to actuate a device, or the fluid pressure can be used as pilot pressure to actuate a pilot operated valve system.
Abstract:
A plug counter includes a seat receptive of a plug in a first position and capable of passing the plug in a second position. A first sleeve is in operable communication with the seat and is longitudinally movable in response to movement of the seat between the first position and the second position. A second sleeve is in operable communication with at least one of the first sleeve and the seat and is configured to index upon passage of the plug. A key is in operable communication with the seat and is configured to prevent movement of the seat to the second position after a selected number of plugs have passed the seat. A third sleeve is in operable communication with the first sleeve, and a release member is in operable communication with the third sleeve and is configured to move the third sleeve after it is released.
Abstract:
A gas supply system is described comprising: a gas capsule (4) enclosed at one end by a pierceable diaphragm (22); a spacer element (20) adjacent the pierceable diaphragm (22), the spacer element (20) having a channel (25) providing access to the pierceable diaphragm (22); a shaft (42) with a piercing tip (38); and a seal (40; 47). The shaft (36), spacer element (20) and seal (40; 47) are arranged so that when the shaft (36) accesses the pierceable diaphragm (22) via the channel (25), the shaft (36) is caused to enter into a sealing engagement with the spacer element (20) via the seal (40; 47) before the piercing tip (38) pierces the pierceable diaphragm (22). In an alternative embodiment (Fig.6), no spacer element (20) is provided and instead a seal (65) is provided in a groove (66) in a wall (32) defining a recess (34) at a position so that when a gas capsule (4) is inserted into the recess (34), the seal (65) enters into a sealing engagement with the gas capsule (4) before the piercing tip (38) of the shaft (36) pierces the pierceable diaphragm (22) enclosing the gas capsule (4).
Abstract:
A device is provided for transferring fluid into or out of a tank and is particularly useful in transferring fluid in a substantially aseptic, hygienic, or sterile manner. The device has a body with an elongate passage extending through the body. The body has a proximal end and a distal end. A longitudinally displaceable cannula is disposed in and extends along the passage in the body. A septum sealing the passage is at a first location; the septum being pierceable and self-sealing. A diaphragm sealing the passage is at a second location intermediate the septum and the distal end of the passage. The cannula extends through and is secured to the diaphragm and has a sharpened end disposed adjacent to or in the septum. Longitudinal displacement of the cannula causes its sharpened end to pierce and project through the septum, the diaphragm stretching to accommodate the displacement of the cannula while maintaining its aseptic seal of the passage.
