Pivoting Pipe Coupling Having a Movable Gripping Body

Номер: US20120256415A1
Автор: Douglas R. Dole
Принадлежит: Victaulic Co

A coupling for securing pipe elements together in end-to-end relation has segments joined at one end by a pivot attachment and at an opposite end by an adjustable connection member. The segments surround a central space which receives the pipe elements. A gripping body is captured between the segments. The segments have angularly oriented reaction surfaces. The gripping body has angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping body radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping body engage and retain the pipe elements. A method of inserting pipe elements into the coupling while the segments and the gripping body are supported on a seal is also disclosed.

Embodiments of a portable verification system can move from one in-field gas flow meter location to another and temporarily connect downstream of a main pipeline's meter run or station. A control valve of the portable verification system allows volume measurement at different flow velocities to be verified. In some embodiments, the portable verification system is connected to the meter run and the main pipeline by a corresponding slip or linearly adjustable pipeline section. This section can extend horizontally and vertically, as well as swivel to provide versatility when connecting in the field. Adaptor fittings having one flange sized for and fitted to the inlet and outlet ends of the portable verification system and another flange sized for the meter run or main pipeline connection provide additional versatility. Downtime is limited to the time required to complete a circuit between the meter run, portable verification system, and main pipeline.

An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.
