Embodiment Construction
[0017] The coupling (pipe fitting) shown in the accompanying drawings, generally designated by the reference numeral 50, comprises (Fig. 1 and Fig. 2) a first fitting 1 and a second fitting 2, the two fittings are formed by respective aligned axial Passages 22 and 23 run through and are connected to each other by quick release coupling means 3, such as described in EP-A-0153773 or in the now pending Italian patent application No. MI2002 A 002196 filed on October 16, 2002 type. The two fittings 1 and 2 are provided with their respective isolation valves 4 and 5 actuated by a single hydraulic motor 6 and linked to each other by rods 7, 8 and linkages 9, 10 (Fig. 1). A hydraulic cylinder 11 ( FIGS. 1-3 ) is provided for operating the coupling device 3 .
[0018] When the first fitting 1 is intended to be coupled in a permanent manner to the first pipe thus forming an integral body with the pipe joint (or more precisely the fitting 1 of the pipe joint), the second fitting 2 is in...

The invention relates to a remote control device used for rapidly joining and rapidly loosening a pipe joint that is arranged on a flanged pipe. The remote control device is used for rapidly connecting the pipe joint onto the flanged pipe. The invention is characterized in that the device comprises a cross piece (13) which is stiffly fixed on one end of the pipe joint so as to be close to the front surface of an end flange (12) of the flanged pipe along the axial direction, at least three lock wheels which extend forwards from the cross pieces at the circumferential interval positions and the lock wheels can rotate around the respective axial cords and a remotely controllable device (19) which is used for controlling the lock wheels to rotate around the respective axial cords. Each lock wheel is a circle with a tangent plane (24) which is slitted along a circle cord so as to allow the flange to go through the flanged pipe at a certain angular position where the circle cord faces the axial cord of the pipe joint and prevent the flange go through the lock wheel at other angular positions, thereby enabling the cross piece and the flange to realize to-and-fro approximation and departure. Each lock wheel is provided with a helical neck which faces the cross piece and is capable of making the flange prop against, join and lock the front side of the cross piece when the lock wheel rotates from one angular position to other angular positions.
Description
technical field [0001] The present invention relates to a remote control device for quick coupling and quick releasing of pipe joints connected to flanged pipes. Background technique [0002] "Joining" a connector for flanges means that the same flanges can be easily joined and separated in a reliable and rapid manner, whether in normal or emergency conditions. [0003] Pipe couplings are known for connecting pipelines in a rapidly separable manner for transporting petroleum products, in particular from ships to land or from land to ships, or from extraction platforms to ships, or from ships to Ships, or extraction wells from ships or platforms to the sea floor, etc. For example, EP-A-0153773 describes a pipe joint comprising two fittings connectable to respective pipes and quick coupling and quick disconnecting means adapted to couple the two fittings to each other, each fitting Shutoff valves are provided respectively. [0004] Such fittings are usually permanently atta...
