Definitions

  • This invention relates to a connection module and a connector.
  • the invention relates to a connector and to a connection module for use in connecting instrumentation equipment to a fluid container such as a process line or pressure vessel.
  • the instruments which are used to take such measurements are typically connected to a fluid container by a system of pipes, manifolds and valves.
  • the connection system can include one or more tapping connections for tapping the fluid container.
  • the instruments which are used to take such measurements require maintenance, such as calibration. In order to carry this out it is necessary to modify the flow of the fluid between the fluid container and the instrument.
  • connection systems are bulky. These systems require a lot of space and are weighty. Indeed, such systems require additional support due to their weight.
  • Manifold systems traditionally have small orifice sizes typically less than 6 mm—this can cause a number of system problems such as becoming clogged by solid particles within a system.
  • gauge line error The phenomena known as gauge line error (GLE) is known in the industry as a potential source of error. This is caused by a combination of the distance between the main process fluid and the instrument, the reduced bore sizes and the level of turbulence caused by the shear quantity of connections between the individual elements of the system. Turbulence associated with GLE can inhibit accurate measurement by an instrument connected to a fluid container. Reducing the path length for fluid flow between a fluid container and a instrument can reduce turbulence and therefore GLE. Known systems struggle to provide a short path length. Longer path lengths also make leaks more probable and more difficult to find.
  • FIG. 1 shows an example of a pipeline 2 , which includes an orifice plate assembly 10 .
  • the orifice plate assembly 10 includes two flanges 4 forming a flanged connection.
  • the orifice plate assembly 10 also includes a plate 6 held between the two flanges 4 .
  • the plate includes an aperture which is smaller than an inner diameter of the pipeline 2 , and is thus designed to reduce the flow of the fluid passing through the pipeline 2 .
  • fluid can be passed to an instrument via tapping points.
  • suitable tapping points are indicated by the arrows 8 . These tapping points 8 are located one on either side of the plate.
  • Pipelines of this kind are relatively crude in construction and thus tapping connection ports provided at the tapping points 8 , although conforming with relevant international standards, can be misaligned with respect to one another. This misalignment can be present in all six degrees of freedom (three translational and three rotational directions).
  • one of the tapping connectors may be misaligned with respect to another tapping connector in any of the x, y or z directions indicated in FIG. 1 .
  • the tapping connectors may also be misaligned in the sense that they are skewed (angled). Accordingly, one of the tapping connectors may be misaligned with respect to another tapping connector in any of the rotational directions ( ⁇ x , ⁇ y , ⁇ y ) indicated in FIG. 1 .
  • connection components can connect directly to a fluid container.
  • a manifold component including valves and so forth can be provided intermediate a connection component and an instrument component.
  • the instrument component can provide a connection to a variety of instrument types, or can itself include an instrument.
  • a manifold block may either be attached directly to an instrument or attached via a further system of tubing or pipe work to a fluid container.
  • the connections must ensure leak free service.
  • the connections must also be capable of accepting additional loads subjected by means of external forces.
  • the joint should also be non-permanent to allow for maintenance.
  • Threaded connections suffer from problems with orientation. Also, users in the offshore industries have a tendency to doubt threaded connections due to issues of crevice corrosion and other ‘hidden’ issues. Moreover, threaded connections are normally limited to small sizes up to around 50 mm (2′′) in diameter.
  • Flanged connections entail large space requirements and are weighty. Systems which use flanged connections require additional support due to their weight.
  • connection module for connecting instrumentation equipment to a fluid container.

  • each jointed tapping connector can be moveable independently of each other jointed tapping connector, thereby to provided additional flexibility.
  • the jointed tapping connector can be configured to move in a number of ways for correcting misalignments.
  • the jointed tapping connector can be pivotable and/or translatable.
  • the jointed tapping connector includes a ball joint. In one embodiment, the jointed tapping connector comprises a double ball joint for additional flexibility.
  • a slotted positioning ring can be provided to aid orientation of the jointed tapping connector.
  • One or more support members can be provided for supporting the connection module against a surface of the fluid container.

  • This connector provides a convenient an efficient means by which, for example, modules in a modular connection assembly can be connected together.
  • an indicator portion can be located substantially in the opening. In this way, when the locking member is slideably received in the opening, the indicator portion is displaced and at least partially protrudes from the opening. This serves to indicate that the locking member is received in the opening.

  • the locking member can be slideably mounted in an aperture of the protruded portion.
  • the locking member can be resiliently biased to protrude from the aperture to be slideably received in the opening of the second jaw member.
  • the locking member comprises a threaded portion for receiving a threaded tool.
  • the tool can thereby be used for withdrawing the locking member into the aperture, thus disconnecting the connector from the corresponding connector.
  • the locking member can be slideably mounted on a stopping member within the aperture. Engagement of the threaded tool with the stopping member and rotation of the threaded tool causes the locking member to ride along the thread of the threaded tool. This causes the locking member to be withdrawing into the aperture.
