Abstract

The invention relates to mechanical engineering and can be applied in hydraulic systems of various machines. The purpose of the invention is to increase efficiency. The device consists of two coupling halves 1 with spring-loaded shut-off valves 7 fixed, it has bushings 3. Inside the coupling half 1, a spacer 9 is installed in the form of a frame fixed on one of the valves 7. When coupling the half coupling 1, the spacer 9 depresses the valves 7 and withdraws from the flow zone. In this case, the coupling halves 1 are placed at an angle to the axis of the valves 7. 2 3. p., 2 ill.

The invention relates to mechanical engineering and can be used in hydraulic systems for tightly connecting hoses with overlapping them in a disconnected position.

The purpose of the invention is to increase efficiency by eliminating the narrowing of the fluid flow by removing the shut-off valves from the flow zone. ; FIG. 1 shows schematically the proposed device, the working position 10; in fig. 2 shows section A-A in FIG. I.: The device contains two coupling halves 1; with steps 2, fixed bushing 3 with slots 4 and annular grooves 5, two

the strips 6 pull out the groove of the sleeve 3, rotate the latter until the steps 2 are aligned with the slots 4, and the pipelines are disconnected. In the disconnected position, the seals of the shut-off valves 7 are pressed by the springs 8 to the surfaces 12, sealing the pipelines.
