Description
Technical field
The utility model relates to technical field of pipeline connection, compensate and seal more particularly, to a kind of fluid hose thermal (temperature difference) stress
With the connection structure of antidetonation.
Background technique
The working principle of clamp-press type pipe is that the bellmouth of thin-wall stainless steel insertion clamp-press type pipe is utilized personality card pressure
Tool is stuck in pipe fitting by stainless steel tube, and cross sectional shape is hexagon or circle, in addition stainless steel tube and pipe fitting at card pressure
Between have O-ring sealing, make it have only leakage, anti-pulling, anti-vibration and the characteristics such as high pressure resistant.Thus it is direct drinking system
One of system, running water system, heating system, vapor system, industrial tubing system and industrial tracheal system are relatively advanced
Connector.Suitable for piping connections such as water, oil, gas.And the connection structure of current clamp-press type pipe, usually in connector tube faucet
The two sides of end bulge loop are crimped；This kind of connection structure does not have buffering shock resistance, big in temperature, pressure and stress variation
Under operating condition, the connected position of the two sides of junction block female end bulge loop easily deforms loosening, leads to leakage and Joint failure, and
Two sides connection is also more time-consuming and laborious.
Utility model content
The purpose of this utility model is intended to overcome the shortcomings of the prior art, and it is good to provide a kind of anti-seismic performance, has
The connection structure of the compensation of the fluid hose thermal (temperature difference) stress of thermal (temperature difference) stress compensation function and good airproof performance and sealing and antidetonation.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
The connection structure of a kind of compensation of fluid hose thermal (temperature difference) stress and sealing and antidetonation, including junction block, are set to junction block
Sealing ring in female end bulge loop, and the connecting tube being plugged in junction block female end；The junction block female end is that S type is held
Mouthful；On the junction block female end, the pipeline section positioned at bulge loop towards connecting tube side be known as linkage section；The linkage section with connect
Pipe is connected by an indent.
Preferably, the junction block is pipe cap, straight joint, three-way connection, elbow or crossover sub.
Preferably, the indent is hexagon or circle.
Compared with prior art, the utility model has the advantages that
(1) the utility model is easy to connect quickly, only towards the one of connecting tube on junction block female end, positioned at bulge loop
Side is crimped, and the other side of bulge loop is not provided with connecting, and with this configuration, in use, bulge loop can be in temperature, pressure
When variation and stress change, the deformation of similar bellows single-unit bellows segment is generated, after bulge loop stretcher strain, outer diameter becomes
It is small, contraction extruding can be carried out to sealing ring, improve the sealability under hyperbaric environment, at the same time, the deformation of bulge loop can shape
At buffering, deformation occurs for the connection at avoidable connected position, and not only anti-pressure ability improves, and anti-seismic performance is also improved.When more
After the connection structure of a the type is applied in combination, it can be equivalent to bellows, used with meeting the biggish occasion of pressure change.And
After temperature, pressure or stress recovery routine in pipe, bulge loop can restore original deformation.
(2) the utility model is designed reasonably science, the great creativeness of selection at the connected position at butt joint tube faucet end are led to
Creative thinking and test are crossed, obtaining the connection structure that this is not found for a long time by people has huge effect
The mechanical characteristic of fruit, the connection structure is effectively excavated and is utilized, and not only reduces installation cost, more crucially it can
The reliability for greatly improving connection has performance more outstanding than the prior art in terms of shock resistance, high pressure resistant to high temperatures.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
The connection structure of the compensation of fluid hose thermal (temperature difference) stress shown in Fig. 1-2 and sealing and antidetonation, including junction block 1, are set to
Sealing ring (not shown) in junction block female end bulge loop 2, and the connecting tube 3 being plugged in 1 female end of junction block；Institute
Stating 1 female end of junction block is S type bellmouth；On 1 female end of junction block, the pipeline section positioned at bulge loop 2 towards 3 side of connecting tube claims
For linkage section 4；The linkage section 4 is connected with connecting tube 3 by an indent 5.
Wherein, the junction block 1 can be pipe cap, straight joint, three-way connection, elbow or crossover sub etc..
The indent 5 is circle, it is clear that can also be hexagon etc..
The installation method of the utility model is as follows:
