SU1528583A1 - Arrangement for cleaning internal surface of pipe-lines - Google Patents

Abstract

The invention relates to the cleaning of pipes with devices moving along the pipe from the inside, can be used in public and water facilities and is aimed at improving operational properties. On the hollow body 1 is placed with the possibility of reciprocating movement of the sleeve 2 with jet nozzles 5 and working nozzles 4. The return spring 6 holds the sleeve in the rear extreme position, and the nozzle 5 communicates with the cavity of the housing 1. The sleeve has a centralizer made in the form of elastic petals 16. When feeding into the cavity of the housing 1 through the flexible hose of the working agent, the latter expires from the jet nozzles 5 and the device moves along the pipeline for the length of the section being processed. Then the hose starts to pull out of the pipeline. At the same time, due to the interaction of the centralizer lobes with the surface of the pipeline, the sleeve moves to the forward extreme position, compressing the spring 6, and working nozzles 4 communicate with the body cavity. This is how the nozzles change operation mode automatically depending on the direction of movement of the device. 2 Il.

Under the action of reactive draft, the device is not mixed inside the pipeline. The hose is thus unwound from the drum of the cleaning mat.

Then, when the device entered the pipeline for the required distance, the hose began to be pulled out of the pipeline, winding it onto the drum of the pipe cleaning machine. In this case, as a result of the interaction of the NAC. of the petals 16 with the pipeline surface, the sleeve 3 moves to the forward extreme position, in which the ipyinia of the working nozzles 4 is communicated with the housing section 1, the angle of inclination of this group of SOCs to the pipeline axis is greater than that of the coil 5, which is aimed at providing an effective cleaning up.

In the presence of the rotor 9 working agent expires from the tangential nozzles ensuring the rotation of the rotor. At the same time, channels 1 I periodically communicate nozzles 4 with nozzles 14 coaxial to them, thus ensuring the pulsed nature of the outflow of working jets.

At the end of the hose extraction, the tension is weakened, and the spring 6 moves the body 1 with the hose forward relative to the sleeve 3, which elastic petals 16 prevent backward movement. Thus, the sleeve 3 moves relative to the body to the rear end position, and the device starts moving E again. before.

The use of the invention allows, by automatically switching the operating mode when the device changes the changing direction of the device, to ensure high-quality cleaning at the maximum length of the treated area.
