Description
Technical field
The present invention relates to pipe technology fields, more specifically to a kind of pressure stabilizing plumbing sealed pipe fittings.
Background technique
With the development of the social economy, more and more people enter urban work and life, since city space is limited, perhaps
The design of more urban facilities cannot be designed more than ground, can be into if planned using the urban design on ground
One step reduces the living space of city dweller, reduces the quality of life of city dweller, also urban design can be made very chaotic；
Especially large size city reaches up to ten million in the resident wherein to live sometimes, and since floor area is limited, municipal sector can be incited somebody to action
The transmission line of electricity of water-feeding drainaging line, burning line and a part is laid on the underground in city, but since pipeline itself has
Certain gravity can cause very big damage if burying the even vehicle that bankets on pipeline again comes that vehicle is past to pipeline, from
And reduce the service life of pipeline.
Summary of the invention
The present invention overcomes deficiencies in the prior art, provide a kind of pressure stabilizing plumbing sealed pipe fittings.
The purpose of the present invention is achieved by following technical proposals.
Pressure stabilizing plumbing sealed pipe fittings, including pipeline body, sealing and interconnecting piece, the both ends difference of the pipeline body
It is provided with the sealing and the interconnecting piece, the sealing includes sealing shroud, sealing lip, pressure bladder, exhaust passage, close
Seal platform and supporting element, it is described to seal the one end for being set on the pipeline body, the sealing station setting the sealing shroud with
The pipeline body connecting place, the sealing lip use cross section to be inverted L-type structure, and the sealing lip is arranged in the sealing
On the inner wall of set, the top of the sealing lip is arranged in the pressure bladder, is arranged on the sealing shroud of the sealing lip bottom
There is seal convexity, form the exhaust passage between the seal convexity and the sealing lip, the supporting element is arranged described
In pressure bladder, the interconnecting piece includes connector sleeve and card slot, and the connection is set on the other end of the pipeline body, institute
The top for stating connector sleeve uses the arcuate structure of outwardly convex, and the card slot is arranged on the outer wall of the connector sleeve, the card
Slot is oppositely arranged with the sealing lip.
The supporting element uses V-type elastic metallic structure, and the distance between the sealing lip and the seal convexity are institute
State the 1/4-1/3 of sealing shroud total length.
The top radian of the connector sleeve is 120-180 °.
The invention has the benefit that by the way that sealing and interconnecting piece is arranged at pipeline body both ends, by sealing and
The sealed connection of interconnecting piece acts on so that being laid with pipeline becomes simpler, and raising pipeline is laid with efficiency and laying quality, when it
In a segment pipe be damaged, which can be replaced, save replacing construction, reduce piping foundation during for
The influence of user；The setting of sealing station and arc connector sleeve, so that there is certain pressure between sealing lip and card slot, thus
Guarantee sealing lip and card slot close connection, avoid as connect it is not close and caused by fluids within pipes or gas leakage；
It is then the sealing performance in order to improve pressure bladder that supporting element is arranged in pressure bladder, since rubber article service life has
Limit, cannot be merely because the ageing of rubber of pressure bladder part replaces whole pipelines, and such cost is excessively high, can by supporting element
Better supporting role is played to pressure bladder, to extend its physical life, is economized on resources.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
In figure: 1 is pipeline body, and 2 be sealing shroud, and 3 be sealing lip, and 4 be pressure bladder, and 5 be sealing station, and 6 is convex to seal
It rises, 7 be connector sleeve, and 8 be card slot.
Specific embodiment
Below by specific embodiment, further description of the technical solution of the present invention.
As shown in Figure 1, wherein 1 is pipeline body, and 2 be sealing shroud, and 3 be sealing lip, and 4 be pressure bladder, and 5 be sealing station,
6 be seal convexity, and 7 be connector sleeve, and 8 be card slot.
Pressure stabilizing plumbing sealed pipe fittings, including pipeline body, sealing and interconnecting piece, the both ends of pipeline body are respectively set
There are a sealing and interconnecting piece, sealing includes sealing shroud, sealing lip, pressure bladder, exhaust passage, sealing station and supporting element, close
Envelope is set on one end of pipeline body, and sealing station setting uses cross section in sealing shroud and pipeline body connecting place, sealing lip
To be inverted L-type structure, sealing lip is arranged on the inner wall of sealing shroud, and the top of sealing lip is arranged in pressure bladder, in sealing lip
It is provided with seal convexity on the sealing shroud of bottom, forms exhaust passage between seal convexity and sealing lip, supporting element is arranged close
It seals in air bag, interconnecting piece includes connector sleeve and card slot, and connection is set on the other end of pipeline body, and the top of connector sleeve uses
The arcuate structure of outwardly convex, card slot are arranged on the outer wall of connector sleeve, and card slot is oppositely arranged with sealing lip.
Supporting element uses V-type elastic metallic structure, and the distance between sealing lip and seal convexity are sealing shroud total length
1/4-1/3。
The top radian of connector sleeve is 120-180 °.
By the way that sealing and interconnecting piece is arranged at pipeline body both ends, acted on by the sealed connection of sealing and interconnecting piece
So that being laid with pipeline becomes simpler, improves pipeline and be laid with efficiency and laying quality, when wherein a segment pipe is damaged, energy
It is enough that the segment pipe is replaced, replacing construction is saved, influence of the piping foundation in the process for user is reduced；Sealing station and
The setting of arc connector sleeve, so that there is certain pressure, to guarantee the tight of sealing lip and card slot between sealing lip and card slot
Close connection, avoid as connect it is not close and caused by fluids within pipes or gas leakage；Support is set in pressure bladder
Part is then the sealing performance in order to improve pressure bladder, cannot be merely because sealing since rubber article service life is limited
The ageing of rubber of cell parts replaces whole pipelines, and such cost is excessively high, can be played more preferably to pressure bladder by supporting element
Supporting role economize on resources to extend its physical life.
It describes the invention in detail, but content is only the preferred embodiment of the present invention, cannot be recognized above
For for limiting practical range of the invention.Any changes and modifications in accordance with the scope of the present application should all still return
Belong within patent covering scope of the invention.
