Description

Description of the invention

The utility model belongs to multi-layer elastomeric taps made of several materials and 2 intended for the corner connection of pipes or pipe fittings in mains for transporting liquid products under pressure or vacuum.

From the state of the art, the closest to the useful model in terms of the number of common features and the result achieved is a multi-layer elastomeric diverter, made in the form of a bent shell, containing an interconnected inner wear-resistant layer and an outer protective layer made of rubber, located between them 70 intermediate layer, made in the form of a reinforcing frame, and end ends ("Multilayer elastomeric tap" ShA29034) (S.M. Kushchenko and S.G. Lipitsky), 12.25.2007, the closest analogue is a prototype)).

Holes for bolted connection with adjacent pipes or pipeline fittings are made in the end ends.

The disadvantage of the known branch is the impossibility of adjusting the position of the end ends intended for 79 connection to adjacent pipes or pipeline fittings, when bolted to connecting elements or flanges of adjacent pipes or pipeline fittings, if the angular positions of their bolt holes do not coincide.

The disadvantage of the known branch is also that it is impossible to create large tightening forces of the joints of the pipes of the multilayer elastomeric branch with adjacent pipes or pipeline fittings with the help of bolted connections.

This is due to the fact that there is a small number of holes for bolts of bolted connections on the small diameter of the end ends.

As a result, with such a small number of bolts, it is not possible to perform reliable tightening of the bolted connections and to ensure the tightness of the joints of the multilayer elastomeric outlet with adjacent pipes or pipeline fittings. -

The technical problem, the solution of which is directed to the useful model, is the improvement of the multilayer elastomeric branch by introducing into its composition movable connecting elements, which have an increased diameter of the circle of the location of the holes for the bolts of the bolted connections for connecting to adjacent pipes or pipeline fittings. i am

The technical result, which is achieved by solving the given problem and using a useful model, consists in ensuring the adjustment of the angular position and increasing the number of holes for bolts in the movable connecting elements, which allows to increase the tightening force and the tightness of the joints of the declared outlet with adjacent pipes or pipeline fittings using bolted connections. at

The technical problem is solved, and the technical result is achieved by the fact that in a multi-layer elastomeric duct, made in the form of a bent shell, containing an internal wear-resistant layer of rubber and an outer protective layer of rubber connected to each other, an intermediate layer is located between them, made in the form of a reinforcing of the frame, and the end ends, the outer surfaces of which are also covered with an outer protective layer of rubber, according to the useful model, additionally contains rings installed on the shell between the end ends with the ability to "move and rotate with respect to the axis of the shell, and are made on the periphery with holes for bolts for bolts connections 70 with adjacent pipes or pipeline fittings. o, c The given features are essential, as they are sufficient in total to solve the technical problem and to achieve the expected technical result, and each separately is necessary to identify and distinguish the claimed multilayer elastomeric pipe from similar technical solutions known from the state of the art.

This set of general and distinctive essential features, which characterizes the claimed multilayer elastomeric lead, is not known from the prior art, is new and sufficient in all cases to which the scope of legal protection extends. o The cause-and-effect relationship of distinctive features in their interaction with known features in achieving the expected technical result, determined by the technical task, is as follows.

Ge) In connection with the fact that the multi-layer elastomeric outlet additionally contains rings installed on the shell -I 20 between the end ends with the possibility of movement and rotation relative to the axis of the shell, the adjustment of the angular position of the holes for the bolts and their coaxial position in accordance with the holes is ensured "sl of connecting elements of adjacent pipes or pipeline fittings when they are connected using bolted connections.

And the execution of rings on the periphery with holes for bolts for bolted connections with adjacent pipes or 29 pipeline fittings ensures that more holes for bolts are located on the increased diameter of the circle, which allows to increase the tightening force and the tightness of the joints of the declared outlet with adjacent pipes or pipe fittings according to using bolted connections.

The multi-layer elastomer tap has other differences that characterize it in certain cases of implementation, to improve its properties. because in a multi-layer elastomeric tap, according to a useful model, the rings are made detachable and consist of several ring segments connected loosely by end parts with the formation of coaxial holes for bolts for bolted connections with adjacent pipes or pipeline fittings.

This design of the rings allows you to install them on the shell after the end ends are made in the form of loosely connected several ring segments, and when connected to adjacent pipes or pipe fittings with the help of bolted connections, it allows you to combine individual ring segments into rings.

From the state of the art, the applicants did not find technical solutions that correspond to the general and distinctive features of the claimed multilayer elastomeric pipe, which indicates that the proposed technical solution is not part of the state of the art and meets the utility model criterion of "novelty".

In the future, the useful model is explained by a detailed description of its design and operation with references to the attached drawings.

A multilayer elastomeric outlet (Fig. 1-7), made in the form of a bent shell 10 (Fig. 1), contains an internal wear-resistant layer 11 of rubber and an external protective layer of rubber 12, located between them (11, 12) intermediate layer 13, made in the form of a reinforcing frame 9, and end ends 14, the outer surfaces of which are also covered with an outer protective layer 12 of rubber.

The peculiarity of the multilayer elastomeric tap is that it additionally contains rings Z0 installed on the shell 10 between the end ends 14 with the possibility of movement and rotation relative to the axis of the shell 10, and made on the periphery with holes 31 for bolts 41 for bolted connections 40 with adjacent pipes or pipeline fittings (Fig. 2).

Bolted connections 40 include bolts 41, nuts 42 and washers 43.

Rings 30 (Fig. 3) can be made removable (Fig. 5-7, modifications 2-4) and can consist of several ring segments 32 connected loosely by end parts with the formation of coaxial holes 31 - for bolts 41 for bolt connections 40 with adjacent pipes or pipeline fittings.

This design of the rings 30 allows you to install them on the shell 10 after the end ends 14 are made in the form of several ring segments 32 connected in a loop, and when connected to adjacent pipes or with pipeline fittings using bolted connections 40, it allows you to connect separate ring segments 32 in rings 30. -

The rings 30 (Fig. 3) can be made in one piece (Fig. 4, modification 1) and installed on the shell 10 in the process of manufacturing a multilayer elastomeric tap before forming the end ends 14.

The reinforcing frame 9 of the intermediate layer 13 of the shell 10 can be made of flexible transverse and c2 longitudinal bundles (ribbons or cords) 8, 7 impregnated with a binder and arranged crosswise to each other. with

The reinforcing frame 9 of the intermediate layer 13 of the shell 10 can be strengthened by at least one spiral rod 7 located on top of the transverse and longitudinal bundles (ribbons or cords) 8, 7.

End ends 14 can include ring frames 15 made of metal or polymer material, for example hard rubber. "

In this case, the longitudinal bundles 7 of the shell 10 cover with loops 5 the ring frames 15 along the entire outer surface.

A multi-layer elastomer tap is used as part of the pipeline as follows. z The produced outlet is connected to the pipe using, for example, flange connections.

For this, in the connecting elements of the ends of adjacent pipes, parallel to the axes of the pipes and coaxial with the holes 31

The ring 30 of the multi-layered elastomeric outlet is made through holes in advance or at the installation site. c Then the adjacent pipes are oriented in space so that the axis of the tap coincides with the axis of the pipe.

Bolts 41 of bolted connections 40 are inserted into the holes 31 of the rings 30 and, with the help of nuts 42 and washers 43, cross-tighten the joints of the end ends 14. sl A slight deviation from the parallelism of the ends of the end ends 14 is compensated by the elastic properties of the outer protective layer 12 of rubber, the flexibility of the end ends end 14, the flexibility of the branch -I in the longitudinal direction and the flexibility of the branch in the transverse direction, in the case when the branch is installed in the gap between two fixed pipes.

Misalignment of the holes of the ZO rings or connecting elements is compensated by the possibility of moving and rotating the rings 30 relative to the axis of the shell 10 of the tap.

And the execution of ZO rings on the periphery with holes 31 for bolts 41 for bolted connections 40 with adjacent pipes or pipeline fittings allows placing more holes 31 s for bolts 41 on the increased diameter of the circle.

This makes it possible to increase the tightening force and tightness of the joints of the multilayer elastomeric branch with adjacent pipes or pipeline fittings with the help of bolted connections 40, which additionally increases the safety of work and the reliability of the connections, especially when the multilayer elastomeric branch is used as part of a pipeline intended for the transportation of liquid products under high internal pressure.

The proposed multi-layer elastomeric diverter can be manufactured many times under conditions of industrial production using standard equipment, modern materials and technology at any polymer engineering enterprise, which indicates that this technical solution meets criterion 65 of the utility model "industrial applicability".
