Description

Adjustment screws 15-18 are installed on the outer surface of the housing, allowing the cross section to be varied. longitudinal channels. With the help of adjusting screws 15, 16, the speed of movement of Porsch 9 can be changed, and with the help of adjustment screws 17, 18, it is possible to influence the speed of movement of Fig. 1,

On the hollow stem 10, near the spool 12, a stop 19 is installed by means of a threaded joint. The mounting housing 7 is located on the side opposite to the clamp 20a and inside the spool 12 a spring 21 is located on the stem 10.

In the housing 7, the fittings 22 and 23 are screwed, to which the hoses 5 and 6 are connected, the ball locks 24 and 25. In addition, the inlet air fitting 26 is mounted on the housing 7 and the outlet channel 27 of the exhausted compressed air is made.

Compressed air flows into choke 26 to spool 12, from which it enters channel 13 and through hollow rod 10 into chamber 8. Simultaneously through choke 22, flexible hose 6, unit 4, air is supplied to treated pipe 2 to pyzhu 1, which moves to node 3. The speed of movement of the py.zh will depend on the flow area of the channel 13 regulated by the screw 17.

Under pressure of compressed air in chamber 8, the pistol 9 moves and drains the spring 21 with its rod, which opens locks 24, 25 and throws the spool 12 to the stop 19. Exhaust air from chamber 8 exits through the longitudinal channel 14 and outlet 27 to the atmosphere.

When moving the spool 12 to the stop 19, the pressure is transmitted through the nozzle

26 and the channel 14 into the chamber 8, and under its action the pistol 9 moves to the cover 20, while the rod 10 moves the spool 12 through the spring 21

in the original position. Exhaust air from the chamber. 8, the channel of the rod 10, the channel 13 of the housing 7, and the channel 27 are released to the atmosphere. Through fitting 23, flexible hose 5 and node 3 air is suitable

to pyzhu 1 and moves to node 4, the speed of movement is regulated by screw 18. The speed of movement of surface 9 is adjusted by screws 15 and 16.

Claims (2)

1. A device for cleaning the inner surface of pipes, including a cleaning Element moved back and forth Suitably under the influence of compressed air along the cavity of the pipe being cleaned, the sealing assemblies and to the Je of the cleaned pipes connected with a source of compressed air and a pneumoswitch, about This is due to the fact that, in order to automate the cleaning process, the pneumatic switch is made in the form of a two-chamber body, in one of the chambers of which there is a piston connected to a hollow rod, and in - the valve, interacting with POLY.M rod, while in the body there are longitudinal channels connecting the valve with the piston and the cleaning element at the same time. 2. The device according to claim 1,.
