摘要:
A fitting element, in particular for an HPLC application, is configured for providing a fluidic coupling of a tubing to a fluidic device. The fitting element comprises a gripping piece to exert—upon coupling of the tubing to the fluidic device—a grip force (G) between the fitting element and the tubing. The gripping piece comprises a hydraulic element configured to transform an axial force (S) into a hydraulic pressure (P) within the hydraulic element. The hydraulic pressure (P) in the hydraulic element causes the grip force (G).
摘要:
A sealing device for a tubing arrangement, preferably for use in an offshore facility, such as an offshore wind turbine or an oil rig. The tubing arrangement has a cable or an inner tube arranged in an interior part thereof. The sealing device comprises a substantially rigid housing and a flexible plug part arranged in an interior part of the housing. The housing is mountable on or forms part of the tubing arrangement in such a manner that the interior part of the housing communicates with the interior part of the tubing arrangement. The flexible plug part comprises an inlet opening connectable to a grout source. When grout material is supplied to the flexible plug part, the flexible plug part expands, thereby providing sealing between the housing and a cable or inner tube arranged in the interior of the tubing arrangement. The sealing device can be mounted on the tubing arrangement before the tubing arrangement is mounted on an offshore facility, and the grout material can be supplied at a later time. Use of divers is thereby minimized. The sealing device can easily be removed and replaced.

An apparatus for repairing a sheath of a pipe includes a sleeve adapted to surround the pipe, at least two circumferential seals between the surface of the pipe and a pressure source for forcing a sealing solution against the surface of the pipe between the two circumferential seals. The apparatus is arranged such that the sleeve is spaced from the outer sheath of the pipe to form a sealed annulus and a sealing solution is introduced into the sealed annulus.

A recreational vehicle waste hose coupling assembly includes a coupler including a sleeve that has a first end wall, a second end wall, an inner wall and an outer wall. An inflation space is defined between the inner and outer walls. A tube has a receiving end and an insertion end and the tube is fixedly positioned within the sleeve. An air pump is fluidly coupled to an air line. The air pump is actuated to inflate the sleeve to frictionally engage the outer wall with an inner surface of a sewer pipe. A feed pipe has an inflow end, an outflow end and a bend between the inflow and outflow ends. The inflow end is removably positionable within a recreational vehicle waste hose. The outflow end is removably positionable within the receiving end.

A fitting element (100), in particular for an HPLC application (10), is configured for providing a fluidic coupling of a tubing (102) to a fluidic device (103). The fitting element (100) comprises a gripping piece (108) to exert—upon coupling of the tubing (102) to the fluidic device (103)—a grip force (G) between the fitting element (100) and the tubing (102). The gripping piece (108) comprises a hydraulic element (170) configured to transform an axial force (S) into a hydraulic pressure (P) within the hydraulic element (170). The hydraulic pressure (P) in the hydraulic element (170) causes the grip force (G).

A sealing device (1) for a tubing arrangement (2), preferably for use in an offshore facility, such as an offshore wind turbine or an oil rig. The tubing arrangement (2) has a cable (3) or an inner tube arranged in an interior part thereof. The sealing device (1) comprises a substantially rigid housing (4) and a flexible plug part (5) arranged in an interior part of the housing (4). The housing (4) is mountable on or forms part of the tubing arrangement (2) in such a manner that the interior part of the housing (4) communicates with the interior part of the tubing arrangement (2). The flexible plug part (5) comprises an inlet opening connectable to a grout source. When grout material (7) is supplied to the flexible plug part (5), the flexible plug part (5) expands, thereby providing sealing between the housing (4) and a cable (3) or inner tube arranged in the interior of the tubing arrangement (2). The sealing device (1) can be mounted on the tubing arrangement (2) before the tubing arrangement (2) is mounted on an offshore facility, and the grout material (7) can be supplied at a later time. Use of divers is thereby minimised. The sealing device (1) can easily be removed and replaced.
摘要:
An apparatus that facilitates tight sealing between a first space and a second space. The second space is at least partially enclosed by a member. The apparatus includes or performs creating or maintaining a pressure difference between a pressure in a third space at a seal assembly and pressure in each of the first space and the second space; and pushing, caused by the pressure difference, against a seal in the seal assembly to tighten sealing provided by the seal.

A fluid union includes a rotatable member with an axis to rotate about, a non-rotatable member, and an actuating member disposed between the rotatable member and the non-rotatable member. The actuating member is moveable along the axis between an engaged position and a non-engaged position and the actuating member is biased towards the non-rotatable member.
摘要:
A seal apparatus including an elongated body formed of a resilient expandable material defining an interior chamber and having a longitudinal axis. The elongated body is capable of being rolled up on itself by rolling one of the first and second ends of the elongated body in a direction parallel to the longitudinal axis. At least one stem is attached to the elongated body and is in fluid communication with the interior chamber.
