The invention relates to the field of hydraulic engineering.

A device for coating the internal surface of the pipeline, where the camera is made in the form of rotation of a body with coaxial holes and provided with a transfer mechanism associated with it by placing the elastic sleeve and passing through the piston traction tape, while the piston is installed on the traction belt to move along it. (A. S. N 1420301 M CL F 16 L the local device for applying a protective coating on the internal surface of the pipeline, containing the delivery system working agent and transported by pipeline elastic Torah mounted with axial clearance relative to each other with the formation of the cavity for adhesive, provided with means for Stripping the coated surface and turbulence in the adhesive is mounted in the cavity for the adhesive. (A. S. N 2014907 M CL F 16 L 55/18 - prototype).

A disadvantage of the known device is the ability to neprokleennye technological sleeve, for moving the pair of elastic tori.

Technical solution to the problem is the reduced flow of the adhesive and improve the quality of the protective coating.

The technical solution is achieved in that the device for applying a protective coating on the internal surface of the pipeline containing the delivery system working agent transported by pipeline elastic torus and the cavity for the adhesive supply system working agent executed as a sealed camera mounted inside the reel on it woven sleeve, as well as starting a camera mounted between the sealed chamber and the conduit, and containing elastic torus, through which is threaded a sleeve, turned end of which is fixed to the input pad, the second camera, and forms a cavity for the adhesive.

The novelty of the claimed proposal due to the fact that the proposed set of structural characteristics reduces consumption of adhesive, because by launching chamber to start the device with the lowest cost of the adhesive, due to the tight end sleeves.

According to the patent and scientific literature the claimed combination of features is not found, which allows to judge about the level of invention proposals.

The essence of the invention is illustrated by the scheme shown in the drawing.

Device for applying a protective coating on the internal surface of the pipeline contains a supply system working agent made of the sealed chamber 1 with the drum 2 on which a flexible sleeve 3, while the airtight chamber 1 is equipped with inlet 4 for feeding a working agent and outlet flange 5, which serves to attach the launching chamber 6. The pre-chamber 6 is designed to accommodate a sealed part of the elastic sleeve 3 and the elastic torus 7, and formed between the cavity 8 through the pipe 9 is pumped by edges the core connection 11 recoverable pipeline 12 by means of a flange 13. Part of the flexible hose 3 is wound from the reel 2 and pass through the interior of the elastic torus 7. After that, the sleeve 3 turn inside out and secured around the perimeter of the outlet flange 5, which serves for connection to the flange 10 launching chamber 6 to the sealed chamber 1. The initial portion of the flexible hose 3 is airtight. The length of this part govern the volume of the adhesive 8 and the size of the toroidal shell 7.

Device for applying a protective coating on the internal surface of the pipeline works as follows.

To run this device starting the camera 6 is connected to the working chamber 1 through the flange 5, 10 and pipe 12 subject to recovery through the flange 11, 13. Under the influence of excess pressure agent supplied through the inlet 4 into the working chamber 1, the sleeve 3 is turned inward launching chamber 6 and forms a cavity of the required amount. The volume of the cavity must be equal to the estimated amount of adhesive for application to the payment site. Relieving excess pressure in the working chamber 1, in the starting chamber 6 is placed an elastic torus 7 threaded through her sleeve 3 and n is 8, after which the pipe 9 is extracted from elastic torus 7. Under the influence of excess pressure agent supplied through the inlet 4 into the working chamber 1, the elastic Thor 7 will exert pressure on the adhesive 8, Prodanova it through the woven sleeve 3, causing movement of the latter on the inner surface of the pipe 12 with the application of the adhesive 8 on its surface, with subsequent pressing woven sleeve by the elastic torus 7.

Device for applying a protective coating on the internal surface of the pipeline containing the delivery system working agent transported by pipeline elastic torus and the cavity for adhesive, characterized in that the supply system working agent executed as a sealed camera mounted inside the reel on it woven sleeve and is starting a camera mounted between the sealed chamber and the pipeline and containing elastic torus, through which is threaded a sleeve, turned end of which is fixed to the input pad, camera, and the initial portion of the inverted sleeve made of airtight fabric length equal to the length of the launching chamber, and forms a cavity for the adhesive.
