Abstract
The invention discloses a kind of self-tightening type pipe fittings, and including sealing ring annular in shape, the sealing ring is made of elastic material, and the medial and lateral at the sealing ring both ends are provided with chamfering, are additionally provided with inflatable chamber in the sealing ring.This pipe fitting can keep sealed reliable for a long time.
Description
Technical field
The present invention relates to Building wood materials and parts art fields, more particularly to a kind of self-tightening type pipe fitting.
Background technique
To save the duration under the premise of guaranteeing construction quality, reducing labour, reduction simultaneously to traffic and people's lives
Caused by influence, in the prior art, underground pedestrian passageway, cable passage, highway culvert, subway tunnel etc. have been all made of prefabricated
Box culvert.Since box culvert is generally embedded in underground, if sealing is bad, underground water is easy to infilter box culvert, destroys box culvert channel interior
Environment, especially on electric power box culvert, people's row, vehicle underground pipe gallery, waterproof seems extremely important, in this case, for building
The sealing joint strip for building field comes into being.
The structure design for advanced optimizing Underground Culvert, is those skilled in the art's technical problem urgently to be resolved.
Summary of the invention
It is that those skilled in the art institute is urgently to be resolved for the structure design for advanced optimizing Underground Culvert set forth above
The technical issues of the problem of, the present invention provides a kind of self-tightening type pipe fitting, this pipe fitting sealed reliables.
A kind of self-tightening type pipe fitting provided by the invention is solved the problems, such as by following technical essential: a kind of self-tightening type pipe fitting,
Including sealing ring annular in shape, the sealing ring is made of elastic material, and the medial and lateral at the sealing ring both ends are provided with down
Angle；
The sealing ring is the hollow structure for being internally provided with inflatable chamber, and the inflatable chamber is annular in shape, and inflatable chamber prolongs
Direction is stretched along the circumferential direction of sealing ring.
In the present solution, the pipe fitting connects the intermediate pipe piece between box culvert for underpass two, using being set as sealing
Ring is elastic material,, can be by elastic-restoring force in this way, be placed between two box culverts and when generating elastic compression in this programme
Enough seal pressures are obtained on sealing surface reaches sealing effect.In the present solution, the medial and lateral for being set as sealing ring both ends are all provided with
It is equipped with chamfering, be used for and the matched flange of chamfering of above chamfering matching box culvert end medial and lateral can position this programme well
With the relative position of box culvert, i.e., so that this programme is good with box culvert relative position stability when in use, makes sealing performance reliable
The characteristics of.
In the present solution, for accommodating compressed gas in the inflatable chamber of setting, in this way, in the present solution, in this stature of sealing ring
When material is deteriorated because of reasons natural resiliency recoverabilities such as agings, as long as the bulk material of sealing ring does not have as the boundary of inflatable chamber
It is destroyed, the air pressure in inflatable chamber lasting power can be provided for sealing ring so that sealing ring can keep remaining close for a long time
Envelope state.
Further technical solution are as follows:
It can optimize or avoid the implementation of stress concentration as one kind, the chamfering is rounded corner.
As a kind of implementation with long service life, the material of the sealing ring is fluorubber.
The invention has the following advantages:
In the present solution, the pipe fitting connects the intermediate pipe piece between box culvert for underpass two, using being set as sealing
Ring is elastic material,, can be by elastic-restoring force in this way, be placed between two box culverts and when generating elastic compression in this programme
Enough seal pressures are obtained on sealing surface reaches sealing effect.In the present solution, the medial and lateral for being set as sealing ring both ends are all provided with
It is equipped with chamfering, be used for and the matched flange of chamfering of above chamfering matching box culvert end medial and lateral can position this programme well
With the relative position of box culvert, i.e., so that this programme is good with box culvert relative position stability when in use, makes sealing performance reliable
The characteristics of.
In the present solution, for accommodating compressed gas in the inflatable chamber of setting, in this way, in the present solution, in this stature of sealing ring
When material is deteriorated because of reasons natural resiliency recoverabilities such as agings, as long as the bulk material of sealing ring does not have as the boundary of inflatable chamber
It is destroyed, the air pressure in inflatable chamber lasting power can be provided for sealing ring so that sealing ring can keep remaining close for a long time
Envelope state.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of one specific embodiment of self-tightening type pipe fitting of the present invention.
Appended drawing reference in figure is successively are as follows: 1, sealing ring, 2, chamfering, 3, inflatable chamber.
Specific embodiment
Below with reference to embodiment, the present invention is described in further detail, but structure of the invention be not limited only to it is following
Embodiment.
Embodiment 1:
As shown in Figure 1, a kind of self-tightening type pipe fitting, including sealing ring 1 annular in shape, the sealing ring 1 is by elastic material system
At the medial and lateral at 1 both ends of sealing ring are provided with chamfering 2；
The sealing ring 1 is the hollow structure for being internally provided with inflatable chamber 3, and the inflatable chamber 3 is annular in shape, inflatable chamber 3
Extending direction along sealing ring 1 circumferential direction.
In the present solution, the pipe fitting connects the intermediate pipe piece between box culvert for underpass two, using being set as sealing
Ring 1 is elastic material,, can be by elastic-restoring force in this way, be placed between two box culverts and when generating elastic compression in this programme
Enough seal pressures are obtained on sealing surface reaches sealing effect.In the present solution, the medial and lateral for being set as 1 both ends of sealing ring are equal
It is provided with chamfering 2, be used for and the matched flange of chamfering 2 of the above matching of chamfering 2 box culvert end medial and lateral can position well
The relative position of this programme and box culvert, i.e., so that this programme is good with box culvert relative position stability when in use, makes leakproofness
The reliable feature of energy.
In the present solution, for accommodating compressed gas in the inflatable chamber of setting, in this way, in the present solution, in this stature of sealing ring
When material is deteriorated because of reasons natural resiliency recoverabilities such as agings, as long as the bulk material of sealing ring does not have as the boundary of inflatable chamber
It is destroyed, the air pressure in inflatable chamber lasting power can be provided for sealing ring so that sealing ring can keep remaining close for a long time
Envelope state.
Embodiment 2:
As shown in Figure 1, the present embodiment is further qualified on the basis of embodiment 1: can optimize or avoid as one kind
The implementation of stress concentration, the chamfering 2 are rounded corner.
As a kind of implementation with long service life, the material of the sealing ring 1 is fluorubber.
The above content is combine specific preferred embodiment to the further description of the invention made, and it cannot be said that originally
The specific embodiment of invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs,
The other embodiments obtained in the case where not departing from technical solution of the present invention, should be included within the scope of the present invention.
