Description

 The present invention relates to the field of engineering, namely: to valves and can be used in hydraulic and pneumatic actuators for quick disconnect pipelines.

 Known quick-disconnect connection of pipelines containing two half-couplings, spring-loaded valves movably mounted in them with cylindrical shanks arranged for reciprocating movement in guide bushings, which are installed by means of radially arranged elements attached to them with the formation of windows for the passage of the working agent and a spring-loaded locking device (1).

 However, the known device does not provide for the regulation of the joining forces.

 Closest to the claimed one is a quick disconnect pipe connection containing two coupling halves, each of which includes a housing with a fitting attached to it by means of a threaded connection, spring-loaded valves with cylindrical shanks arranged for reciprocating movement in guide bushings, movably mounted in the housings which are installed by means of attached to them radially arranged elements with the formation of windows for the passage of the working agent and spring-loaded locking device (2).

 The disadvantage of this device, as well as the above, is the lack of regulation of the joining force.

 The technical effect achieved in the quick disconnect connection of pipelines of the claimed design is to provide regulation of the joining forces.

 To achieve this technical effect, a quick-connect pipe connection containing two coupling halves, each of which includes a housing with a fitting attached to it by means of a threaded connection, spring-loaded valves with cylindrical shanks arranged for reciprocating movement in the guide bushings, movably mounted in the housings which are installed by means of radially arranged elements attached to them with the formation of windows for the passage of the working gent, and a spring-loaded locking device, equipped with support bushings rigidly attached to radially arranged elements, made with an external thread for interaction with the threads of the housings, and mounted with the possibility of axial movement with their subsequent fixation, and interchangeable washers, while the end surfaces of the fittings are axial stops for support bushings, and interchangeable washers are installed between the support bushings and axial stops.

 This embodiment of the quick disconnect allows you to provide regulation of the joining forces.

 The proposed quick connection meets the criteria of "novelty" and "inventive step".

 The drawing shows a quick connection in a docked position in section.

 The quick-disconnect connection of pipelines contains external and internal half-couplings, which include housings 1 and 2 with fittings 3, 4 attached to it by means of a threaded connection. Valves 5, made with cylindrical shanks 6 arranged with the possibility of reciprocating movement in the guide bushings 7. To the bushings 7 are attached with the formation of windows for the passage of liquid or gas radially located elements 8, which in turn are rigidly ikrepleny supporting sleeve 9 formed with external threads for interaction with threaded housings 1, 2 are arranged movably threadedly with subsequent fixation. The end surfaces 10 of the fittings 3 and 4 are axial stops for the support sleeves 9. Between the axial stops 10 and the support sleeves 9 are interchangeable washers 11.

 The quick-release locking device consists of balls 12 located in the sockets of the locking sleeve 13 of the female coupling half and interacting with the annular groove of the male coupling half.

 Quick disconnect piping works as follows. When joining the connection, the locking sleeve 13 is shifted. In this case, the balls 12 enter the annular groove on the male coupling half, and the valves 5 are recessed in the housing, freeing the passage for liquid.

 To disconnect the coupling halves, the locking sleeve 13, overcoming the resistance of the spring 14 is displaced in the opposite direction until it stops. Balls 12 fall into the annular groove of the retainer sleeve. The inner coupling half is removed from the outer coupling coupling.

 Changing the joining forces is as follows. Having removed the fittings 3 and 4 and the bushings 9, move the bushings 9 along the thread towards the half-connector and install the necessary number of replaceable washers 11 between the support bushings 9 and the axial stops 10. The support bushings 9 abut against the replaceable washers 11 or axial stops 10. The springs 15 change their rigidity.
