Drain and removal equipment, including connection end pieces and connectors for such equipment

Abstract

The invention relates to a discharge and purge device (10) suitable for limiting the pressure of the fluid (F) occupying the internal volume of a connection end piece (2), comprising a valve or a valve actuating piston, opening outwards in front of the valve or piston (22) An inner enclosure (30) and an occluder (60) movable between a closed position (C1) and an open position. The device (10) also includes a first chamber (50) defined when the occluder (60) is in the closed position, a communication channel (36) between the first chamber (50) and the internal volume of the end piece (2) , means (96) for returning the occluder to the closed position, and the second chamber (40). The first sealing section (S92) is smaller than the second sealing section (S94).

Description

technical field [0001] The present invention relates to a drain and purge device comprising a valve or a valve-actuated piston, adapted to restrict the flow of fluid occupying the internal volume of a connection end piece connected to a conduit and which, when combined, can reduce The residual pressure of the fluid. The invention also relates to a connection end piece comprising such a device. The invention also relates to a connector comprising a male connection end piece, a female connection end piece and at least one such device. The field of the invention is that of connectors for removable couplings of conduits for pressurized gas and / or liquid fluid communication. Background technique [0002] The connector includes two connecting end pieces, respectively a male end piece and a female end piece, each comprising a fluid vessel and connectable to each other to form a fluid transport line. A movable valve is typically positioned at the connection interface between the ...

Problems solved by technology

[0005] Furthermore, in the case of specific applications such as cooling of electronic packs via cooling plates, the constraints on the connection of variable pressure boost lines are particularly complex

Different systems partly give the possibility to deal with the problem of line clearing and limiting the pressure rise, but none can fully solve the manual coupling of the pressurized line, or the ejection of the gasket once the valve is opened, the exact opening conditions of the line are uncertain , blockage of the connection system, or even damage to the connector due to pressure rise in the line
