Abstract
The utility model discloses a kind of circular metal high-temperature expansion joint, comprise a hydraulic cylinder, described hydraulic cylinder is provided with a metal catheter, the end of described metal catheter is provided with one first union joint, being additionally provided with an elastomeric pad on hydraulic cylinder, a hydraulic stem is connected through described elastomeric pad with hydraulic cylinder elasticity, and the end of described hydraulic stem is provided with one second union joint, connect for screw rod between described elastomeric pad and hydraulic cylinder, the first described union joint and the second union joint are respectively provided with one layer of aluminium flake.Circular metal high-temperature expansion joint of the present utility model is provided with a hydraulic cylinder and a hydraulic stem on body, instead of traditional corrugated tube torsion with hydraulic telescopic machanism to stretch, even the retractility of expansion joint also by large effect, thus will not ensure the stability of pipeline in high temperature environments.
Description
Technical field
This utility model relates to a kind of expansion joint, more precisely, be a kind of circular metal high-temperature expansion joint.
Background technology
Expansion joint is the additional stress caused because of temperature difference and mechanical vibration for compensation, and is arranged on container casing or pipeline
On a kind of flexible structure.Owing to it is as a kind of elastic compensation element that can freely stretch, there is reliable operation, performance good
The advantages such as good, compact conformation, have been widely used in departments such as chemical industry, metallurgy, nuclear energy.
The expansion joint that at present industry commonly uses mostly is bellows expansion joint, but the elasticity that corrugated tube is in high temperature environments
Can be by large effect, mechanical performance is poor.
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus provides one in high temperature environments
There is the circular metal high-temperature expansion joint of preferable mechanical performance.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of circular metal high-temperature expansion joint, comprises a hydraulic cylinder, and described hydraulic cylinder is provided with a metal catheter, described
The end of metal catheter is provided with one first union joint, and hydraulic cylinder is additionally provided with an elastomeric pad, and a hydraulic stem passes described elasticity
Pad is connected with hydraulic cylinder elasticity, and the end of described hydraulic stem is provided with one second union joint.
As this utility model preferred embodiment, connect for screw rod between described elastomeric pad and hydraulic cylinder.
As this utility model preferred embodiment, the first described union joint and the second union joint are respectively provided with one layer of aluminum
Sheet.
Circular metal high-temperature expansion joint of the present utility model is provided with a hydraulic cylinder and a hydraulic stem on body, uses
Hydraulic telescopic machanism instead of traditional corrugated tube torsion and stretches, even the retractility of expansion joint also will not in high temperature environments
By large effect, thus ensure the stability of pipeline.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the perspective view of circular metal high-temperature expansion joint of the present utility model；
Fig. 2 is the side view of the circular metal high-temperature expansion joint in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
As shown in Figure 1 and Figure 2, a kind of circular metal high-temperature expansion joint 1, comprise a hydraulic cylinder 2, described hydraulic cylinder 2 is provided with
One metal catheter 3, the end of described metal catheter 3 is provided with one first union joint 4, hydraulic cylinder 2 is additionally provided with an elastomeric pad
5, a hydraulic stem 6 is connected through described elastomeric pad 5 with hydraulic cylinder 2 elasticity, and the end of described hydraulic stem 6 is provided with one second connection
7.
Further improve as to this utility model, connect for screw rod between described elastomeric pad 5 and hydraulic cylinder 2.
Further improve as to this utility model, the first described union joint 4 and the second union joint 7 are respectively provided with
One layer of aluminium flake.
The circular metal high-temperature expansion joint of this utility model is provided with a hydraulic cylinder and a hydraulic stem on body, uses
Hydraulic telescopic machanism instead of traditional corrugated tube torsion and stretches, even the retractility of expansion joint also will not in high temperature environments
By large effect, thus ensure the stability of pipeline.
Mentality of designing of the present utility model is below described the most in one embodiment, in the case of system allows,
This utility model can expand to the most external more functional module, thus extends its function to greatest extent.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
