Abstract

The invention relates to mechanical engineering and can be used in hydraulic drives of agricultural and agricultural technology. The purpose of the invention is to improve the design and the expansion of technological capabilities. The joint contains split sleeves 3 and 4, on the inner cylindrical surfaces of which protrusions 5 and 6 are made, fixing them on the pipes. The outer sleeve 3 communicates with the inner sleeve 4 and with the yoke 2 over surfaces of varying diameter. When the axial movement of the cage 2 and the cap nut 1 is reciprocated, due to the mechanical connection, the pipes move.

The invention relates to machinery, in particular to assembly units, and can be used in agricultural hydraulic drives. technology.

The aim of the invention is to increase the reliability and expansion of technological capabilities through the connection of pipes of various l, and diameters.

FIG. I depicted the connection ,. general form; on fkg. 2 connection with different pipe diameters; on jjHr. 3 is the same when the pipe is connected to the choke; in fig. 4 and 5 - 15 times cut through the bushings until the tube is crimped, section; in fig. 6 the same, after compression of the pipe.

The quick disconnect connection of pipelines consists of a cap nut 1, 20 externally connected to the yoke 2, which interacts with an external split sleeve 3, interacts with the sleeve n and turn with an internal split sleeve 4. On the inner 25 cheshindry surfaces of the sleeves there are protrusions 5 and 6. High-quality connection provides sealing element 7.1.

Quick disconnect pipe-30 operates as follows.

With mutual captive. nuts 1 and casing 2 in the axial direction of the casing 2 acts on the outside-1gun) split bushing 3, 35-protrusion -1 and 5 are fixed in coal inclusions on the pipe, by means of a surface of variable diameter. Due to this, the outer sleeve 3 tightly compresses the pipe and together with it

moves axially towards the pipe to be connected. At the same time, the outer sleeve 3 is its outer -: inner surface of variable diameter acts on the inner one.

the cutting sleeve 4, fixed with its protrusions 6 in the recesses on the pipe, crimping it. Due to this, the internal sleeve 4 tightly compresses the pipe. Since the cap nut 1 with the inner surface presses against the inner split sleeve 4, the inner side of the sleeve 4 moves axially along with the pipe to the pipe being joined. At the approaching of the pipes, the condensate, and the hydraulic element element 7 ensures the quality of the joining of the pipes.

Claims (2)

1. A quick-disconnecting connection of pipelines containing a clip, sealing element of the outer and inner bushings, mounted on the connected pipes with the possibility of mutual displacement 5 distinguishing. so that, in order to simplify the design and expand the technological capabilities, it is equipped with a nakidia nut, articulated thread with a cover and an installed capability. interaction with the end surface of the inner sleeve, and the outer sleeve is split and in contact with the inner sleeve and ferrule along surfaces of variable diameter, while on the surfaces of both sleeves adjacent to the pipes, protrusions are made, and recesses on them are 7. 2. A compound according to claim 1, characterized in that, in order to expand technological capabilities due to the possibility of connecting pipes of different diameters, the split sleeves are made of an elastic material and have an internal diameter that is / different from the diameter of the pipe to be connected.
