Abstract

FIELD OF THE INVENTION The invention relates to mechanical engineering and concerns the connections of hydraulic and pneumatic main pipelines. The purpose of the invention is to increase the reliability and ease of operation. The quick coupling device includes a housing 1 with a piston pneumatic actuator 2 in the form of a piston 3, a return spring 4 and a hollow rod 5. It is possible to use a hydraulic actuator. The control working medium is supplied through the fitting 6, the supporting hose 7. On the housing 1, a clamp 8 is fixed, providing during its movement the pressing of the tip 9 to the gasket 10. On the pipeline of the first working medium a stop valve 11 is installed, which interacts with the rod 12. The valve 11 is pressed spring 13. Sealing head 14 provides sealing tip 10. The working medium is supplied through the fitting 15. 2 Il. (Ls

Description

The invention relates to mechanical engineering, in particular to devices for connecting consumers with pneumatic or hydropower,

The aim of the invention is to increase the reliability of the connection of the pipeline to the pressure source and ease of operation,

FIG. 1 shows a device with a pneumatic actuator of the executive body, a longitudinal section; in fig. 2 - a device with a hydraulic actuator.

The quick coupling device comprises a housing 1 with a piston pneumatic actuator 2 in the form of a piston 3, a return spring 4 and a psycho-output 5. The use of a hydraulic drive is possible (see Fig. 2). The control working medium is supplied

through fitting 6 carrying the hose 7. On the housing 1, a bracket 8 is fixed, providing during its movement the pressing of the tip 9 to the gasket 10. A shutoff valve 11 is connected to the first working medium pipe and interacts with the rod 12. The valve 11 is pressed by the spring 13. The sealing head 14 provides sealing of the tip 10. The working fluid is supplied through the nozzle 15.

The following movements are characteristic of the connecting device:

and - the amount of movement of the piston 3 ;. c is the amount of movement of the bracket 8; c is the amount of movement of the sealing head 14; d is the amount of displacement of the head 9 in the gasket 10. The supply pipeline is marked with 1, the plug is connected with P.

High-speed coupling device operates as follows.

A cap 9 is inserted into the slot of the bracket 8 and placed on the gasket 10. Compressed air from the pneumatic system is supplied to fitting 7. By compressing the return spring 4, the housing 1 begins to descend, moving by the amount a. When moving by the amount of, the clamp 8 comes into contact with the tip 9 and begins to act on the gaskets of the sealing head 14,

After the sealing head 14 is moved by the value end (see Fig. 1), the downward valve of the valve 11 compressing the spring 13 moves downwards. The holes in the rod of the sealing head 14 open, keeping contact with the / valve of the valve 11, which at that moment loses its sealing function. The working medium goes to the tip 9.

Disconnection of the source from the consumer is carried out as follows.

When the pressure in the housing 1 decreases, under the influence of the return spring 4, it begins its movement, retraction of the stops of the bracket 8 from the tip 9. The gaskets of the sealing head 14 restore their original shape and the stem of the sealing head 1.4 moves to the outer

upper position by c + d. The supply of working medium is immediately stopped. Upon further movement of the bracket 8 upwards, it is possible to remove the tip.

9. When idle, when the cap 11 is not installed or installed with unacceptable distortions, the supply of working medium will not.
