Description

The invention relates to the field of pipeline transport and can be used to seal the annular space and the passage of communication cables in the protective pipe through the sealing bend of the cuff in the transitions of the main pipelines laid in the protective casing (case) under roads and railways. The rubber cuff is a product consisting of two annular cylindrical sections, one cylindrical section is made with a diameter of 57-1420 mm, the second cylindrical section is made with a diameter of 219-1720, and the conical section connecting them. On the conical section of the rubber cuff, a tap was made as a unit with the cuff. The tap is intended for passing communication cables in a protective pipe when it becomes necessary to lay the cable inside the casing (case) in the transitions under roads and railways.

A device for communicative input-output with a housing for cable transition fixing and sealing elements (see RU 2120692, CL 6 N 02 G 3/22 from 10/20/1998).

The sealing element is made in the form of an elastic sleeve, one end of which is fixedly mounted on the flange of the housing wall with a bandage, and the second is fixedly fixed on the sleeve. The disadvantage of this technical solution is the complexity of manufacturing. To ensure dust and water tightness and tightness in the device, several parts are used.

The objective of the invention is to create a rubber cuff with two annular cylindrical sections, one cylindrical section is made with a diameter of 57-1420 mm, the second cylindrical section is made with a diameter of 219-1720, and the conical section connecting them to seal the annular space. On the cone section as a unit with the cuff, a tap was made. The branch is intended for the passage of communication cables in a protective pipe in the transitions of pipelines laid in a protective casing (case) under roads and railways. In addition, the cuff outlet must provide reliable sealing between the outer diameter of the cable protective pipe and the rubber bend, as well as the convenience of laying and installing communication cables through the cuff outlet on the support rings in the transitions.

The invention provides options with two or more taps for passing protective pipes of communication cables. The distance between the branches in their lower part is 10-100 mm.

The essence of the invention lies in the fact that in a rubber cuff containing a conical section connecting two cylindrical sections of different diameters, one cylindrical section is made with a diameter of 57-1420 mm, the second cylindrical section is made with a diameter of 219-1720 for sealing the annular space, a bend for cable passage is made communication in the protective pipe. The tap was made at an angle of 30-45 ° on the conical portion of the cuff, hollow in the shape of a cone, as a unit with a rubber cuff, with an inner diameter of 10-100 mm, a wall thickness of 3-8 mm in its upper part, and in the lower part the inner diameter 20-120 mm, wall thickness 3-9 mm.

The conical design of the rubber bend is designed to pass the protective pipes of the communication cables and secure them in the bend of the cuff, as well as the cuff seals the annular space in the transitions of the main pipelines. Sealing between the walls of the cable protective pipe and the walls of the cuff outlet is achieved due to the smaller internal diameter of the outlet by 15-20% with respect to the outer diameter of the protective pipe of the communication cable. An exact selection of the diameter of the branch for reliable sealing is made by transversely cutting the upper conical part of the branch of 10-20 mm so that the protective pipe of the communication cable enters the bend of the sleeve with an interference fit and is tightly sealed in the branch due to the difference between the inner diameter of the branch and the outer diameter of the protective communication cable pipes.

The invention provides options for a rubber cuff with two or more bends for passing various diameters of protective pipes of communication cables with a distance between them of 10-100 mm. For reliable sealing of the annular space, the cylindrical sections of the cuff are made with a diameter of 57-1420 and 219-1720 mm. The cuff is assembled when the transition of the main pipeline is mounted and the protective pipe of the communication cables protrudes 200-800 mm beyond the protective casing.

The invention is illustrated by drawings:

- figure 1 - General view of the cuff with one branch for passing communication cables side view;

- figure 2 is the same, front view;

- figure 3 - transition of the main pipeline Assembly;

- figure 4 - General view of the cuff with two bends for the passage of communication cables, front view;

The rubber cuff is made with a tap 1 (figure 1, 2) for passing communication cables 2 (figure 3) in a protective pipe 3 (figure 3), is a conical shape product 4 (figure 1) with a thickness of 3-10 mm, contains two cylindrical sections 5, 6 (Fig. 1), one for securing the cuff on the main pipeline 7 (Fig. 3) with a diameter of 57-1420 mm, the second for securing to the casing-case 8 (Fig. 3) of a transition with a diameter of 219-1720 mm

On the conical section of the rubber cuff 4 (figure 1) at an angle of 30-45 ° to the generatrix of the cone of the cuff, a tap 1 (figure 1, 2) is made as a unit with the cuff. It is made hollow with a wall thickness of 3-8 mm in the upper part, at the base, the wall thickness of the branch is 3-9 mm. The tap is made in the upper inner part with a diameter of 10-100 mm in the lower inner part with a diameter of 20-120 mm.

Sealing between the walls of the protective pipe 3 (FIG. 3) of the cable 2 (FIG. 3) and the outlet 1 (FIG. 3) of the cuff is achieved due to the smaller internal diameter of the outlet by 15-20% with respect to the outer diameter of the protective tube 3 (FIG. 3) communication cable (2 figure 3) cuff. An exact selection of the diameter of the outlet 1 (Fig. 1) for reliable sealing is made by transversely cutting the upper conical part of the outlet A-A, B-B, B-B (Fig. 1) of 10-20 mm so that the protective pipe 3 (Fig. 3) of the communication cable entered the bend of the sleeve 1 (Fig. 1) with an interference fit and was tightly sealed in the bend 1 (Fig. 1) due to the difference between the inner diameter of the outlet 1 (Fig. 1) and the outer diameter of the protective pipe of the communication cable 3 (figure 3).

The claimed invention provides an option for a rubber cuff with two 9, 10 (Fig. 4) or more bends for passing protective pipes of communication cables, when it becomes necessary to lay two or more communication cables in separate protective pipes in the transitions of trunk pipelines under roads and railways.

Assembly of the cuff is as follows.

Before assembling the cuff, the inner diameter in the upper part 1 (Fig. 1) of the outlet and the outer diameter of the protective tube 3 (Fig. 3) of the communication cables 2 (Fig. 3) are measured. The diameter of the branch in the upper conical part should always be 15-20% less than the outer diameter of the cable protective pipe, this will reliably seal the protective pipe of the communication cables in the branch. If the inner diameter of the cuff outlet is 42 mm, then the outer diameter of the protective pipe of the communication cables should be 48-50 mm. The exact selection of diameters is carried out by transverse cutting of the upper conical part of the outlet AA, BB or BB (Fig. 1) of 10-20 mm. With each cutting increases the inner diameter of the branch 1 (figure 1). The selection is carried out in such a way that the protective pipe 3 (Fig. 3) of the communication cable 2 (Fig. 3) is inserted into the bend of the sleeve 1 (Fig. 3) with an interference fit and is tightly sealed in the bend.

The assembly of the rubber cuff with tap 1 (Fig. 1) is carried out when the transition is assembled (Fig. 3), the main pipeline 7 (Fig. 3) is extended into the protective casing-case 8 (Fig. 3) on the support rings 11 (Fig. 3) ), the protective pipe 3 (Fig. 3) of the communication cables is fixed in the upper part of the support rings 11 (Fig. 3) of the transition with clamps 12 (Fig. 3) and protrudes from 200-800 mm from the casing (case) on both sides of the transition.

The rubber sleeve is mounted on the main pipeline 7 (Fig. 3) and it is moved to the casing-cartridge 8 (Fig. 3) and the protective tube 3 (Fig. 3) of the communication cable 2 (Fig. 3). In the outlet of the cuff 1 (Fig. 1), the protective pipe 3 (Fig. 3) is passed with an interference fit and, moving further along the main pipeline 7 (Fig. 3), the cylindrical part 6 of the Fig. 1 of the cuff 13 (Fig. 3) is fixed on the casing (case) clamps ties 14 (figure 3). Then they push it into the inside of the casing (case), forming a corrugation 15 (figure 3), and fix it on the main pipeline with clamps 16 (figure 3). On the opposite side of the transition, the assembly of the cuff 17 (figure 3) with a tap 18 (figure 3) is produced similarly to the assembly of the cuff 13 (figure 3).

The assembly of a rubber cuff with two or more bends for passing communication cables in a protective pipe is performed in the same way as with one bend.

The conical rubber cuff will reliably seal the annular space and the protective pipes of communication cables in the transitions of the main pipelines under roads and railways, laid in a protective casing (case).

The described cuff works in the same way as a conventional rubber cuff works under similar conditions, with small axial movements of the main pipeline and the protective pipe of the communication cables in the cuff outlet, that is, the annular space is sealed with protective pipes in the cuff outlet.
