Fluid connector with hose cutting blades

Номер: US20120161437A1
Автор: Michael P. Wells, Scott A. Smith
Принадлежит: Individual

An electrically conductive hose cutting clip has at least one cutting blade that is shaped to provide a cutting edge for penetration of the inner layer(s) of a multiple layer fluid conveyance hose when it is clipped onto a fluid connector and the hose is installed on the fluid connector by forcing it onto the connector. The cutting action by the cutting blade provides for a relatively low resistance electrical connection between an electrically conductive layer of the hose and the fluid connector. This can be used to provide a signal path from a sensing element on the hose to a system electronic component.

An assembly for a torque-transmitting connection in an inner pipe string of a dual-member drill string is formed from a collar, a retaining ring, and an inner pipe member. An endless internal groove having adjacent shallow and deep sections is formed in the collar. Formed in the inner pipe member, an endless external groove is situated in concentric relationship with the internal groove. The retaining ring, situated within the grooves, resists disconnection of the collar from the inner pipe member. When the assembly is subjected to an axial force that might otherwise tend to pull it apart, the retaining ring resists the tendency by wedging between the bottom of the shallow section of the internal groove and the crest of the external groove. 1. An assembly , comprising:a tubular collar having opposed first and second ends and an endless internal groove positioned adjacent the first end in which the groove has a step-like base defining adjacent shallow and deep sections;a pipe member having an end positioned within the collar and an endless external groove positioned adjacent the end of the pipe member and situated in concentric relationship with the internal groove; anda retaining ring situated within the grooves of both the collar and the pipe section.2.

A pipe coupling for coupling adjacent pipe ends of a pair of pipes includes a sleeve, a sealing gasket operatively coupled with the sleeve adjacent an open end of the sleeve, and a clamping element for compressing the sleeve or the sealing gasket into tightened engagement with one of the pipe ends. The clamping element includes two bolt flanges nominally spaced apart by a gap and a double threaded fastening bolt with two external threaded portions, which engage with two corresponding fastening nuts having right-hand thread and left-hand thread, respectively. Accordingly, when the fastening bolt is rotated, both of the fastening nuts move towards or away from one another, thereby rapidly moving the bolt flanges to shrink the gap and compress the clamping element or to expand the gap. As such, less time and labor are required to operate the pipe coupling in the field. 1.
