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.

Known rubber cuff according to patent No. 2261388 C1, IPC 7 F16J 15/00 for passing communication cables in the transition, which is manufactured informally and is a product consisting of two cylindrical sections, for a trunk pipeline with a diameter of 57-1420 mm, for a casing (case ) with a diameter of 219-1720 mm, 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 made with a wall thickness of 3-8 mm in its upper part, with a diameter of 20-120 mm.

The disadvantages of this rubber cuff are the lack of corrugation, as a result of which when moving the main pipeline in the casing (case) with increasing or decreasing temperature of the pumped product, as well as when seasonal temperatures change, the rubber cuff breaks or slides from the edge of the casing (case). As a result, there is a depressurization of the annulus of the transition. Moisture enters the annular space, as a result, the wall of the casing (case) and the supporting-guide rings are destroyed and, as a result, an accident occurs in the transition of the pipeline. The cuff has limited versatility, as it cannot perform several functions. In addition, the cuff has a high cost, a large weight of up to 50 kg, as well as low productivity and a culture of rubber cuff production.

The objective of the invention is to eliminate the disadvantages of the known cuff and the development of a rubber cuff with corrugation without tap, with a plugged conical and with a plugged conical-slotted bend for passing the protective pipes of the communication cable, which is performed as a unit with the cuff, the rubber cuff with the bend can be used as without a protective cable for the communication cable, or with a protective pipe with a diameter of 16-83 mm for the communication cable by removing the plug on the branch or cutting off part of the branch according to the mark for the corresponding diameter of the protective cable Uba communication cable.

The cuff is made of rubber according to modern technology by the method of molding in the mold. In addition, the weight of the rubber cuff should be reduced by half compared with the existing conical rubber cuff, which is manufactured informally, which will significantly improve the quality, culture of production and labor productivity.

The essence of the invention lies in the fact that the rubber cuff is made with corrugation without bend, with a muffled cone and with a muffled cone-slotted bend. Each branch is made as a single unit with a cuff for passing protective pipes of communication cables when it becomes necessary to lay them in the pipeline passage.

The rubber cuff without branch and with branch is made of two cylindrical sections with an inner diameter of 57-1420 mm for the main pipeline and an outer diameter of 219-1720 mm for the casing (case), which are connected by the corrugated part of the rubber cuff. The corrugation on the rubber cuff is made with a sufficient radius to move the main pipeline in the casing (case) in both directions. When the temperature of the pumped product increases or decreases, and also when seasonal temperatures change, when the main pipeline moves to one side, during this period the cuff does not slip from the casing (case) due to the corrugation, and therefore, the tightness of the annular transition space is not broken due to corrugation cuffs.

In addition, the cuff is made of rubber both with an offset and without an offset center.

Between the outer cylindrical wall of the inner diameter and the base of the outer part of the corrugation, a tap was made as a unit with a rubber sleeve to pass the protective pipe of the communication cable with a diameter of 16-83 mm. The tap is made in the form of a cone or in the form of a flat cone with a wall thickness, sufficient strength and reliable sealing of the protective pipes of the communication cables in the bend of the cuff when moving the pipeline. In the upper part of the conical and conical-slotted outlet 2-5 mm from the end inward, a plug is made as a unit with the outlet. The plug is removed manually with a knife when there is a need to lay a protective pipe with a diameter of 16 mm for communication cables into the branch of the transition cuff. A tap in the form of a cone is performed when the difference between the diameters of the main pipeline and the casing (case) is 200 mm or more. If the difference between the diameters of the main pipeline and the casing (case) is less than 200 mm, then the branch for the protective pipe of the communication cable is tapered-slotted because the place for placing the branch is limited by the annulus of the transition and the radius of the cuff corrugation.

The conical rubber bend is made as a unit with a cuff in the shape of a cone. On the outer surface of the tap, top-down numbers are plotted in increasing order with risks that correspond to the standard diameters of the protective pipes of the communication cables for passing the cuff into the tap.

The risks shown below the numbers indicate the lateral cut-off lines for the passage of the matching diameter of the protective pipe of the communication cables.

The tapered slotted outlet is made as a single unit with a cuff in the form of a flat cone. On the outer surface of the branch, the figures with the risks for cutting corresponding to the diameter of the protective pipe of the communication cables are plotted from top to bottom as in the conical branch. Cone and cone-slotted bends are designed to pass and seal the protective pipes of communication cables of a given diameter due to the smaller internal diameter of the branch with respect to the outer diameter of the protective pipe of the communication cable, and also taking into account the tensile properties of the branch made of rubber.

The cuff is made of rubber according to modern technology by molding in a mold without a tap, with a tapered or tapered slotted bend, which are designed for protective pipes of communication cables.

The conical and cone-slotted bends in the manufacture are calculated taking into account the tensile properties of the rubber bends in the cuff when the protective pipes of the communication cables are pulled into it, due to which reliable sealing is carried out.

A rubber sleeve with a cone and a rubber sleeve with a tapered-slotted outlet can be used both with a protective pipe of the communication cable when removing the plugs on the branch, and without a protective pipe without removing the plugs in the branch during the construction of the pipeline under the automobile and railways, laid in the protective cover (case).

The rubber sleeve without bend can be used without limiting the diameters only for sealing the annulus during the construction of transitions.

The essence of the method of manufacturing a rubber cuff is that the cuff is made without tap, with a muffled cone and with a muffled cone-slotted tap in the mold with both a displaced center and without a displaced center. In a mold for the manufacture of a rubber cuff, a crude rubber preform is laid in sectors overlapping each other by 2-4 mm over the entire inner surface of the mold, taking into account the cuff wall thickness of 4-10 mm. A raw rubber billet for a conical or cone-slotted outlet is made and placed in a mold separately with the expectation that the wall thickness of the outlet of the vulcanized cuff is sufficient to seal the protective pipe of the communication cables, and the outlet was plugged in its upper part.

Then, the prepared rubber cuff from crude rubber in the mold is vulcanized in a vulcanizing press at a temperature of t = 143-150 ° C for 30-55 minutes. After the set time has passed, the vulcanized rubber cuff is removed from the mold, cooled, the burr removed and quality control of the cuff is performed. A rubber sleeve with a plugged cone bend and a rubber sleeve with a plugged conical-slotted bend are designed for use with or without a protective pipe for the communication cable. To use a cuff with a bend to pass the protective pipe of communication cables after vulcanization, perform the following operations: a vulcanized rubber cuff with a tapered or tapered-slotted bend is placed upward with a bend and a knife is cut along the circumference of the inner diameter of the bend, the rubber cuff is ready for use with a cable protective pipe communication with a diameter of 16 mm. For the use of protective pipes for communication cables with a diameter of 20-83 mm, the plug on the branch is not removed, but part of the branch is cut across, at the mark on the branch, corresponding to the diameter of the pipe. If the rubber cuff is used without a protective pipe for communication cables, then the plug on the branch pipe is not cut out, and the cuff with the plugged pipe branch is installed on the trunk pipeline.

The rubber sleeve without retraction is made in a similar manner. The sleeve without tap is used to seal the annulus of the transition without the protective pipe of the communication cable.

The essence of the method of assembling the rubber cuff on the transition pipeline is that the lash of the main pipeline is pulled with the protective pipe of the communication cable on the support guide rings with rolling bearings, either with sliding bearings, or with combined supports, so that when the lash leaves a protective casing (0.5-1 m) for the convenience of installation came out of the casing (case) in its upper part. After that, the outer diameter of the protective pipe of the communication cables is measured, it must coincide with the diameter indicated on the outer surface of the cuff outlet. According to the measured risk of the corresponding diameter, the end of the branch is cut across. The resulting hole is designed to pass with an interference fit of the protective pipe of communication cables.

The applied measured risks under the numbers on the bend of the cuff are calculated in the manufacture taking into account the tensile properties of the rubber bend for tight compression of the communication cable by the bend of the protective pipe. As a result, complete dust and water tightness between the walls of the outlet and the protective pipe of the communication cable is ensured.

The diameters of the outlet with numbers on the conical part of the rubber sleeve are smaller in relation to the outer diameter of the protective pipe of the communication cable, which contributes to reliable sealing of the protective pipe of the communication cable in the outlet of the rubber sleeve.

Then the rubber cuff is mounted on one of the ends of the extended lash of the main pipeline of the transition and move it to the casing (case) and the protective pipe of the communication cable. The protective cable of the communication cable is passed with an interference fit into the cut-off rubber cuff, pre-wetted with water for the length of the pulling, then the rubber cuff is further advanced through the main pipeline to the casing (case) and the cylindrical parts of the cuff are fixed on the main pipeline and the casing (case) with tie straps . Then visually monitor the compression by tapping the protective pipe of the communication cable. On the opposite side of the transition, the cuff assembly with the tap is made in a similar way and the transition is covered with soil.

A method of assembling a rubber cuff on a transition pipe without a branch and with a drowned branch is carried out in a similar manner. A rubber sleeve with a cone or with a cone-slotted outlet allows you to reliably seal the annulus in the transition of the pipeline, and also provides complete dust and water tightness between the walls of the outlet and the protective pipe of the communication cables. In addition, a rubber sleeve can be used in a pipeline transition with both a protective pipe of communication cables and without a protective pipe of communication cables, which significantly expands the range of its application in the construction of pipeline transitions in a protective casing (case).

The rubber cuff consists of two cylindrical sections 1, 2 and the corrugated part 3 connecting them (FIGS. 1, 2, 4, 7). The cuff is performed without a tap (FIGS. 1, 2, 3), either with a blanked tapered tap 4 (Figs. 4, 5, 6), or with a blanked tapered tap-hole tap 5 (Figs. 7, 8, 9), which are made as a unit with the cuff, for the passage of the protective pipes of the communication cables 6 (Fig.4, 7), when it becomes necessary to lay them in the transition pipeline.

The rubber cuff without branch (Fig. 2, 3) and the cuff with branch 4 (Fig. 4, 5, 6, 8, 9) are made of two cylindrical sections: section 1 with an inner diameter of 57-1420 mm for the main pipeline 7 and section 2 with an outer diameter of 219-1720 mm for the casing (case) 8 (Fig. 1, 4, 7), which are connected by a corrugated part 3 (Fig. 1, 2, 3, 4, 5, 7). Corrugated section 3 on a rubber cuff is made with sufficient step to move the main pipeline in the casing (case) in both directions. When the temperature of the pumped product increases or decreases, and also when seasonal temperatures change, when the main pipeline moves to one side, the cuff does not slip from the casing (case) during this period, therefore, the tightness of the annular transition space due to the corrugation is not broken .

In addition, the cuff is made of rubber both with a displaced center and without a displaced center (Figs. 1, 4, 7).

Between the outer cylindrical wall of the inner diameter and the base of the outer part of the corrugation 3, a tap was made as a unit with a rubber sleeve to pass the protective pipe 6 of the communication cable with a diameter of 16-83 mm. Branch 4 (figure 5) is a cone, in the upper part of which is made a plug 9 (figure 5, 6). The tap 5 (Fig. 8) is made in the form of a conical slit; in the upper part of the cone-slotted tap, a plug 10 (Fig. 8, 9) is made as a unit with the tap.

The plug is removed manually with a knife 11 (Fig.6, 9) when the diameter of the protective pipe 6 for communication cables is 16 mm, or part of the tap is cut across the marks to the corresponding diameter of the protective pipe of communication cables, when there is a need to lay it in the outlet of the cuff transition. A tap in the form of a cone is performed in the case when the difference between the diameters of the main pipeline 7 and the casing (case) 8 (figure 4) is 200 mm or more. If the difference between the diameters of the main pipeline and the casing (case) is less than 200 mm, then the branch for the protective pipe of the communication cable is tapered-slotted because the place for placing the branch is limited by the annulus of the transition and the radius of the cuff corrugation.

The conical rubber bend (figure 5) is made as a unit with a cuff in the shape of a cone. On the outer surface of the tap, top-down numbers are plotted in increasing order with risks that correspond to the standard diameters of the protective pipes of the communication cables for passing the cuff into the tap.

The risks shown below the numbers indicate the lateral cut-off lines for the passage of the matching diameter of the protective pipe of the communication cables.

The conical-slotted outlet is made as a single unit with a cuff in the form of a flat cone (Fig. 8). On the outer surface of the branch, the figures with the risks for cutting corresponding to the diameter of 16-83 mm of the protective pipe of communication cables are plotted from top to bottom as in the conical branch. Cone and cone-slotted bends are designed to pass and seal the protective pipe of communication cables of a given diameter due to the smaller diameter of the branch with respect to the diameter of the protective pipe of communication cables, and also taking into account the tensile properties of the branch made of rubber.

The cuff is made of rubber according to modern technology by molding in a mold both without a tap (FIGS. 2, 3), and with a conical (FIGS. 5, 6) or with a tapered-slotted (FIGS. 8, 9) tap, which designed for protective pipes of communication cables.

The conical and cone-slotted bends in the manufacture are calculated taking into account the tensile properties of the rubber bends in the cuff when the protective pipes of the communication cables are pulled into it, due to which reliable sealing is carried out.

The protective pipe 6 (Fig. 7) of the communication cable stretched into the conical-slotted outlet is partially pressed into the side of the corrugation, while not interfering with its operation and increases the space for the cuff to retract. A rubber sleeve with a tapered or tapered slotted outlet can be used both with the protective pipe of the communication cable when removing the plug on the branch or cutting off part of the branch according to marks for the corresponding diameter of the protective pipe of the communication cable, and without the protective pipe without removing the plug on the branch during the construction of the transition pipeline 7 under roads and railways, laid in a protective casing (case) 8.

Corrugation 3 (Fig. 2, 5, 8) on a rubber cuff is made with a sufficient radius to move the main pipeline in the casing (case) in both directions with increasing or decreasing temperature of the pumped product, as well as with changing seasonal temperatures, without disrupting the cylindrical soil pressure part of the cuff from the casing (case) and without violating the tightness of the annulus of the transition. A rubber sleeve without a tap (FIGS. 2, 3) can be used without restriction of diameters only for sealing the annulus during the construction of transitions. The proposed rubber sleeve is designed to seal the annulus and seal the protective pipe of the junction cables.

The rubber cuff works with a cone (Fig. 5, 6) or with a cone-slotted (Fig. 8, 9) bend as follows: when the temperature of the pumped product increases or seasonal temperatures change, the main pipeline axially moves to one side, resulting in the cuff mounted on the casing (case) 8 and on the main pipeline 7 (Figs. 1, 4, 7) with the help of tie clamps 12, 13 (Figs. 1, 4, 7), does not tear off the casing (case) 8, and moves together with the main pipeline 7 due to the corrugation of the cuff. In turn, the protective pipe 6 of the communication cable also moves together with the main pipeline, and the tensile forces on the cuffs are also not affected by the rubber outlet for the protective pipe, which is folded into the shape of a stocking on the protective pipe of the communication cable. When the temperature of the pumped product decreases in the corrugation pipe 3, the cuffs and the outlet for the protective pipe of the communication cable return to their original position, and this is repeated every time when the axial movement of the pipeline occurs in the transition to one of the sides. Rubber cuff without tap (figure 2, 3) works in the same way as the cuff with tap (figure 5, 6, 8, 9).

The essence of the method of manufacturing a rubber cuff is that the rubber cuff is performed with a corrugation both without a tap (FIGS. 2, 3), and with a plugged conical (FIGS. 5, 6) or with a plugged conical-slotted (FIG. 8, 9 ) withdrawal by molding in a mold both with a displaced center and without a displaced center. A blank of raw rubber for the rubber cuff is laid in sectors overlapping each other by 2-4 mm over the entire inner surface of the mold. A raw rubber billet for cone and cone-slit taps is made and placed in the mold separately with the expectation that the bend is made with a plug in its upper part.

After that, the product is vulcanized in a vulcanizing press at a temperature of t = 143-150 ° C for 30-55 minutes. Then, the vulcanized rubber cuff is removed from the mold, cooled, the burr removed and quality control of the cuff is performed. A rubber sleeve is made without a tap, with a plugged tapered tap or with a tapered slotted tap, which is designed to be used both with the protective cable of the communication cable by cutting the plug on the pipe, and without the protective pipe of the communication cable without removing the plug on the pipe.

Then, the vulcanized rubber sleeve is laid with a tapered or tapered slotted bend upwards and a knife 11 is cut around the circumference of the inside diameter of the outlet with a plug 9, 10 and the rubber sleeve is ready for use with a protective tube with an outer diameter of 16-83 mm for the communication cable. During installation, the tap is cut off according to the marks on the tap for the corresponding diameter of the protective pipe of the communication cables. If a rubber cuff with a bend is used without a protective pipe for communication cables, the plug on the bend is not cut out, and a cuff with a muffled bend is installed on the main pipeline of the transition and it is operated with a bent bend.

The rubber cuff without retraction (figure 2, 3) is made in a similar way. The sleeve without bend is used without restriction in diameter to seal the annulus of the transition without the protective pipe of the communication cable.

A method of assembling a rubber cuff on a transition pipeline with a protective pipe of communication cables is as follows: support rings 14 (FIGS. 4, 7) with rolling bearings or with sliding bearings are mounted on the dragged pipeline. In the upper part of the support guide rings on the brackets 15 establish a protective pipe of communication cables 6.

Then drag the lash of the main pipeline 7 with the protective pipe 6 of the communication cable on the supporting guide rings 14 (Fig. 4, 7) into the casing (case) 8 so that when the lash leaves the casing (case) in its upper part, the protective pipe 6 communication cables came out at 0.5 ÷ 1.0 m for the convenience of mounting the cuff. After that, the outer diameter of the protective pipe of the communication cable is measured, for example, if it is 20 mm, the figure “20” is found on the branch of the rubber cuff and the end of the branch is cut off along the line under the number “20”. The rest of the tap on the cuff is designed to pass and seal the protective pipe of 6 communication cables. The applied measured risks on the cone and cone-slotted outlet with the numbers of the outer diameters of the protective pipes of the communication cables are calculated taking into account the tensile properties of the rubber branch for reliable sealing of the protective pipe in the branch of the rubber sleeve. The inner diameter of the branch in the upper conical part is less than the outer diameter of the cable protective pipe, this will allow you to reliably seal the protective pipe of the communication cables in the branch.

Then, with a prepared hole for passing the cable protective pipe, a rubber sleeve is mounted on one of the ends of the extended whip of the transmission main pipeline and moved to the casing (case) 8 and the protective pipe of the communication cable 6 (Figs. 4, 7). In the prepared diameter of the rubber cuff outlet, the protective pipe 6 of the communication cable is tightened, pre-moistened with water for the length of pulling. Next, the cuff is advanced along the main pipe 7 to the casing (case) 8 and the cylindrical parts 1, 2 of the cuff are fixed on the main pipe 7 and the casing (case) 8 with tie clamps 12, 13 (Figs. 4, 7). Compression by the tap of the protective pipe of the communication cable is carried out due to the tensile properties of the rubber tap.

On the opposite side of the transition, the assembly of the rubber cuff with a tap on the transition pipeline is carried out in a similar manner.

The method of assembling a rubber cuff without a tap or with a muffled tap on the transition pipeline is carried out in a similar way, but without skipping the protective pipe of the communication cable.

A rubber sleeve without a tap, with a tapered or tapered slotted tap will find the widest application for reliable sealing of the annular space and the protective pipe of communication cables in the transition when laying communication cables in protective pipes with specified diameters during the construction of transitions of main pipelines laid in the protective casing (case) under roads and railways.

The rubber cuff is made of rubber according to modern technology by the method of molding in the mold, which significantly improves the quality, production culture and labor productivity. The weight of the rubber cuff is reduced by more than two times in comparison with similar rubber cuffs made by an informal method, which significantly reduces its cost and the cost of packaging and transportation.

In addition, a rubber sleeve with a cone or with a cone-slotted tap is used both with the protective pipe of the communication cable and without it. This has allowed to expand the scope of application of the rubber cuff, in addition, it contributes to the rational use of raw materials and materials for its manufacture with a significant economic effect for the enterprise.
