The utility model discloses a sealing structure for a pipe socket, which comprises a first pipe and a second pipe, and the ends of the first pipe and the second pipe are respectively provided with a first socket and a second socket. The first pipe socket is provided with a first annular groove and a second annular groove for placing a sealing ring, the sealing ring arranged in the first annular groove and the sealing ring arranged in the second annular groove Water-swellable rubber strips are also arranged between them. The utility model has a simple structure, can re-seal the pipe socket, further improves the sealing performance of the socket, reduces the number of times of rework, and saves costs.
Description
Technical field
The utility model relates to water engineering field sealing configuration, relates in particular to a kind of pipeline socket sealing configuration.
Background technique
As the conventional Prestressed concrete cylinder pipe of carrying water in current water engineering, there is long service life, both economical feature.Due to the special internal structure of prestressed pipe, sealing just becomes particularly important.Prestressed concrete cylinder pipe is general now adopts two cushion rubbers to carry out flexible sealing connection.But in pipe transport and handling process, seal ring unavoidably can be impaired, pinpoint the problems and need to repair once banket after burying, pipeline must be dug out, again repair and return and bury again afterwards.This process not only expends a large amount of manpower and materials, and can delay the normal operation of water system.
Model utility content
Because the above-mentioned defect of prior art, the utility model provides a kind of simple in structure, good seal performance, joint socket sealing configuration easy to use.
For achieving the above object, the utility model provides a kind of pipeline socket sealing configuration, comprise the first pipeline and second pipe, described the first pipeline and described second pipe end are respectively arranged with the first joint socket and the second joint socket, described the first pipeline socket is provided with first ring connected in star and the second annular groove for placing seal ring, is arranged at the seal ring of described first ring connected in star and is arranged between the seal ring of described the second annular groove to be also provided with hydro-expansive rubber bar.
Preferably, the thickness of described hydro-expansive rubber bar is less than the gap between described the first joint socket and described the second joint socket.
Preferably, described seal ring is rubber ring.
Preferably, described rubber ring adopts neoprene.
Preferably, be also provided with pressure testing hole on described second pipe, described pressure testing hole correspondence is arranged between described first ring connected in star and described the second annular groove, and described pressure testing hole connects the wall of described second pipe.
The beneficial effects of the utility model:
Adopt said structure of the present utility model, owing to having increased again water-swellable bar between two seal rings, this expansion bar is not subject to any External Force Acting in the time that the sealability of seal ring is intact, and damage and can not seal liquid time when a certain seal ring, the expansion of water-swellable bar, seals again to pipeline socket, thereby further improves the sealability of joint socket, reduce the number of times of doing over again, cost-saving.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 the present embodiment interface tube double-wedge seal with elastometic washer structural representation;
Fig. 2 the present embodiment interface tube double-wedge seal with elastometic washer structure axis view.
In figure: the first pipeline 1, the first outer diameter tube 12, the first internal diameter of the pipeline 12, first ring connected in star 13, the second annular grooves 14, second pipe 2, second pipe external diameter 21, second pipe external diameter 22, seal ring 3, hydro-expansive rubber bar 4, pressure testing hole 5.
Embodiment
As depicted in figs. 1 and 2, the present embodiment has proposed a kind of pipeline socket sealing configuration, comprise the first pipeline 1 and second pipe 2, the first pipeline 1 and second pipe 2 ends are respectively arranged with the first joint socket and the second joint socket, and the external diameter of the first pipeline socket is provided with first ring connected in star 13 and the second annular groove 14 for placing rubber seal 3.When mounted, be also provided with hydro-expansive rubber bar 4 being arranged at first rubber seal 4 of first ring connected in star 13 and being arranged between second rubber seal 4 of the second annular groove 14.
The thickness that is arranged at the hydro-expansive rubber bar 4 before above-mentioned two rubber seal is less than installs the gap between the first joint socket and described the second joint socket after seal ring.Therefore, in the time of the favorable sealing property of first seal ring and second seal ring, hydro-expansive rubber bar 4 is not subject to any extruding, once the sealing effect of two rubber seal is lost, whom has infiltrate the gap between two rubber seal, hydro-expansive rubber bar will expand, and then stops liquid further to infiltrate, thereby further improves the sealability of joint socket.
In the present embodiment, neoprene is owing to having the swelling characteristic of the vegetable oil of chance, and rubber seal adopts neoprene, to ensure its good sealability under use state.
On second pipe 2, be also provided with pressure testing hole 5, pressure testing hole 5 correspondences are arranged between first ring connected in star 13 and the second annular groove 14, and pressure testing hole 5 connects the wall body of second pipe 2.
The concrete applicable cases of the present embodiment pipeline socket sealing configuration is as follows: before installation, and the fitting surface of pipe blow-through joint socket at relevant position brushing food and lubricant oil (vegetable oil), and first rubber seal is infiltrated in lubricant oil; Rubber seal is inserted in groove, and ensures that the even hoop of rubber ring is in groove.Use the same method, by second rubber seal hoop in the second annular groove; When installation, the first rubber seal is advanced after second pipe, hydro-expansive rubber bar 4 is arranged between first rubber seal and second rubber seal, and then row is installed; Check and rear seal ring is installed and whether is in place met water rubber strip, as found displacement, need to reinstall.After confirming to install correctly, by pressure testing hole 5, the pipeline after installing is carried out to the hydrostatic test.
In the present embodiment, the concrete test method of pipeline socket sealing configuration sealability, according to approach well known, is no longer described in detail at this.
Can find by concrete application above, the expansion bar in pipeline socket sealing configuration of the present utility model is not subject to any External Force Acting in the time that the sealability of seal ring is intact, and installs simple yet.And damage and can not seal liquid time, water-swellable bar water-swellable, seals again to pipeline socket, thereby further improves the sealability of joint socket, reduces the number of times of doing over again, cost-saving when a certain seal ring.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
