Abstract

The invention relates to mechanical engineering and is intended for the joining of pipelines in hard-to-reach places and products of cryogenic engineering. The purpose of the invention is to simplify the technology and reduce the time to dock and disconnect the connection. In the quick coupling, the nut 3 is made in one piece with the driven shaft 6 of the reversing clutch 5 one-way, and on the drive shaft 7 of the clutch 5 a handle 8 is fixed to transfer torque to the nut. When the drive shaft 7 is moved, the coupling with the elements of the driven shaft 6 occurs. The handle 8 can be extended by extending the levers 9. 1 Cp. f-ly, 3 ill.

.one

The invention relates to mechanical engineering and can be used for connecting and disconnecting pipelines under pressure from a gas or liquid.

The aim of the invention is to reduce the time of joining and disconnecting the connection due to the use of a reversible coupling.

FIG. 1 shows a quick coupler, a slit; in fig. 2 is a section A-A in FIG. one; in fig. 3 - LEAD B in FIG. 2

The quick-release coupling comprises housings 1 and 2, fastened together by means of a nut 3, mounted rotatably on the housing 1, fitting 4, made in one

arrow or counterclockwise. The nut 3 is mated with clamp 4. In order to increase the tightening torque of the nut 3, the knob 8 is lengthened by extending the levers 9. When the knob is in the middle (neutral) position, the shaft 7 rotates without transferring torque to the nut 3.

I. A quick-release coupling consisting of two bodies with valves placed in them, fastened to each other with a nut mounted rotatably on the first of the bodies, as well as a plug made in the second body, integral with the body 2, reversible muf- 20 o.klichayuschayesya that, that 5 free running, driven shaft 6, in order to simplify the design and which is complete in one piece with the shortening of the docking time and the unlocking nut 3, and on the drive shaft 7 it is equipped with a reversible flap handle 8. In the last coax and the one installed in the first case are placed levers 9 with a possible 25 and having driven and driving shafts, one of which is made in one move value along the axis of the handle. To dock or uncouple the joint, the drive shaft 7, by moving along the joint axis to one side or the other, mates with the corresponding elements of the driven shaft 6 in order to transfer torque to nut 3 in a clockwise direction. with a nut and a handle on the other. 2. The connection according to clause I, clause 30 is, in order to reduce the dimensions, the handle is made from a set of levers coaxially placed in each other with the possibility of axial movement. arrow or counterclockwise. The nut 3 is mated with clamp 4. In order to increase the tightening torque of the nut 3, the knob 8 is lengthened by extending the levers 9.
