DEVICE for cleaning PIPELINE SURFACE VITRIA.

The utility model relates to the field of pipeline transport and can be used in gas, oil and other industries for cleaning the inner surface of pipelines from contaminants and foreign objects, removing gas condensate mixtures from gas pipelines, finally releasing pipelines from water or air when they are filled with water, etc. P.

A device is known for cleaning the inner surface of a pipeline, comprising a housing provided with thrust washers; the casing is provided with annular cleaning elements with a spacer sleeve between them, one of the thrust washers being installed with the possibility of longitudinal movement along the housing surface, and the cleaning elements and spacer sleeves placed freely, which makes it possible to regulate the clamping forces of the treatment elements to the wall of the pipeline Copyright certificate of the USSR No. 444573, VV 9/04, publ. 09/30/74, bull. Number 36.

The disadvantage of this device is the low quality of cleaning the pipeline and the possibility of jamming of the device when passing through the pipeline with steeply bent turns.

The closest to the claimed combination of essential features is a device for cleaning the inner surface of the pipeline, including ring cleaning elements made of elastic material mounted in series on a flexible connection, which are adjacent to one another, other than the extreme cleaning elements, there are bushings located in them and placed in the latter perpendicular to them axis by partitions, and a flexible connection is made in the form of several cables fixed around the circumference in the partitions of the bush Property No. 725725, B08B 9/04, publ. 04/05/80, bull. Number 13.

A disadvantage of the known device is the low quality of cleaning the inner surface of the pipeline due to the limited resource of the elastic material of the annular cleaning elements, as well as the low efficiency of overcoming bends and turns of the pipeline with a radius of curvature of less than five pipe diameters (R 5 d).

The inventive utility model solves the problem of improving the quality of cleaning the inner surface of the pipeline and ensuring the effective overcoming of bends and turns of the pipeline.

The problem is solved in that the device for cleaning the inner surface of the pipeline, containing installed in series on a flexible connection, the annular cleaning elements made of elastic material, and tightening their node, consists of at least

two sections of the cleaning elements, interconnected by means of a flexible connection and installed between the sections of the sleeve, and is equipped with disk cuffs installed between the cleaning elements.

The length of each section corresponds to the inner diameter of the pipeline.

In addition, in the internal part of the device is installed a signaling device location in the pipeline.

Due to such a constructive implementation of the device, a new technical result is achieved, which consists in improving the quality of cleaning the inner surface of the pipeline, due to the presence of disk cuffs from a more durable elastic material (polyurethane), and preventing the possibility of a device getting stuck in the pipeline due to the unhindered overcoming of bends and turns of the pipeline due to the presence of less than two sections of treatment elements, each of which has a length corresponding to the inside it pipe diameter.

In FIG. 1 shows a device for cleaning the inner surface of the pipeline, figure 2 - section aa in figure 1.

The device for cleaning the inner surface of the pipeline consists of at least two sections of elastic cleaning elements. Each section contains mounted on a flexible connection 1 ring cleaning elements 2 made of elastic material, between which there are disk cuffs 3 made of polyurethane, separated by gaskets 4, and rigidly fastened together by fasteners, for example, studs 5 with nuts. The sections are fastened together by two studs 6, and the studs are equipped with bushings 7 to provide the necessary clearance between the sections. At the same time, the sections are held on the axis by means of a tightening unit including a flange 8 with a welded loop to which one end of a flexible connection is fastened, for example, a cable, a flange 9, a threaded rod 10 with a thread attached to the other end, and a nut 11, if necessary which sections are pulled together.

The length of each section should correspond to the internal diameter of the pipeline. In a specific embodiment of the device, the number of annular cleaning elements in the section is two, but may be different.

Inside the device, an alarm 12 of the place is located while it is in the pipeline.

A device for cleaning the inner surface of the pipeline works as follows.

The device is stored in the pipeline and under the action of the medium (liquid or gas) entering the pipeline it moves along the cavity of the pipeline being processed, cleaning it with cuffs 3 of accumulated water and condensate.

When the device passes through sections of the pipeline having a smooth bend, the first section bends relative to the second section, and the device passes freely through the pipeline, while passing the device through bends and turns of the pipeline with a radius of curvature that are welded from pipes cut at an angle, the movement of the first section is somewhat inhibited , while the second section continues its movement for some time, contracting due to the elasticity of the elastic ring elements 2. After that, the first section under the action of the expanding I pushed through the pipe forces turn.

In addition, the proposed device can always be found thanks to the built-in signaling device 12 of the location of the device in the pipeline.

Thus, the use of the proposed device allows to ensure high-quality cleaning of pipelines of any configuration and the effective overcoming of bends and turns of the pipeline.
