Passive tube closure valve
| DWPI Title: Passive pipe closure valve for crimping flow path, to prevent and/or stop fluid flow through portion of pipeline, has passageway that extends along axis different from another axis, and modifying structure connected to end of elongated body |
| Abstract: A passive tube closure valve comprising an elongated body extending along a first axis made of a shape memory alloy with a threshold contraction along the first axis at a threshold temperature. The closure valve further comprises a passageway extending along a second axis different from the first axis shaped to surround a conduit line extending along the second axis. The closure valve further includes a first modifying structure on a first portion of the passageway and a second modifying structure on a second portion of the passageway opposite the first modifying structure. Contraction of the elongated body can cause the first modifying structure and the second modifying structure to move towards each other; where movement of at least one of the first modifying structure or the second modifying structures can be configured to modify the conduit line. |
| Use: Passive pipe closure valve for crimping a pipeline i.e. flow path, to prevent and/or stop fluid flow through a portion of the pipeline. |
| Advantage: The elongated body is provided with a shape memory alloy with a threshold contraction along the first axis at the threshold temperature, where passageway is extended along a second axis, thus preventing stop fluid flow through a portion of the pipeline in easy and simple manner. |
| Novelty: The valve (100) has an elongated body (102) extending along an axis, where the body comprises a shape memory alloy e.g. nickel titanium alloy, with a threshold contraction along the axis at threshold temperature. A passageway (104) extends along another axis different from the former axis, and is shaped to surround a pipeline (106) extending along the latter axis. A modifying structure is connected to an end of the body, where movement of the modifying structure permanently modifies the pipeline. A stabilizer bar (116) extends between ends of another body. A pole (118) extends between the bar and the structure. |
