Abstract
The utility model discloses a novel special expansion joint of cold tight pipeline intelligence contains a first connector and a second connector, connect a bellows between first connector and second connector, cup joint a thermal -insulated pipe in the bellows, thermal -insulated pipe is mixed by asbestos and glass fiber to be made, the thermal -insulated intraductal polyvinyl chloride plastic pipe that still cup joints, the polyvinyl chloride plastic pipe is mechanical high temperature crimping with thermal -insulated pipe. The utility model discloses a novel special expansion joint of cold tight pipeline intelligence has cup jointed a polyvinyl chloride plastic pipe and a thermal -insulated pipe in the inboard of bellows, and thermal -insulated pipe can effectively prevent intraductal low temperature fluid infringement bellows, and the polyvinyl chloride plastic pipe can increase the intensity of thermal -insulated pipe, and this expansion joint can use under low temperature environment for a long time.
Description
Technical field
This utility model is related to a kind of expansion joint, more precisely, being a kind of cold tight pipeline intelligent new exclusive expansion joint.
Background technology
Expansion joint is for compensating the additional stress causing because of temperature difference and mechanical vibration, and is arranged on container casing or pipeline
On a kind of flexible structure.Because it is as a kind of elastic compensation element that can freely stretch, there is reliable operation, performance good
Well, the advantages of compact conformation, have been widely used in departments such as chemical industry, metallurgy, nuclear energy.When used for expansion joint in connecting cryogenic piping
When, the cryogen in pipeline can cause larger infringement to general expansion joint, even with the very short time later
Function can be lost and cannot use.
Utility model content
This utility model is mainly the technical problem solving existing for prior art, thus providing a kind of cold tight pipeline intelligent
New exclusive expansion joint.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals：
A kind of cold tight pipeline intelligent new exclusive expansion joint, comprises one first union joint and one second union joint, and described the
A corrugated tube is connected between one union joint and the second union joint, socket one instlated tubular in described corrugated tube, described instlated tubular is by asbestos
Be mixed with glass fibre, in described instlated tubular, be also socketed a pvc tube, described pvc tube and every
Heat pipe crimps for mechanical high-temperature.
As this utility model preferred embodiment, described corrugated tube is double-wall corrugated pipe.
As this utility model preferred embodiment, the thickness of described pvc tube and instlated tubular is than for 2：7.
Cold tight pipeline intelligent new exclusive expansion joint of the present utility model has been socketed a polychlorostyrene second in the inner side of corrugated tube
Alkene plastics pipe and an instlated tubular, instlated tubular can effectively stop cryogen infringement corrugated tube, pvc tube in pipe
The intensity of instlated tubular can be increased, this expansion joint at low ambient temperatures can be with life-time service.
Brief description
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 in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of cold tight pipeline intelligent new exclusive expansion joint of the present utility model.
Specific embodiment
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 make apparent clear and definite to protection domain of the present utility model
Define.
As shown in figure 1, a kind of cold tight pipeline intelligent new exclusive expansion joint 1, comprise one first union joint 10 and one second
Union joint 20, connects a corrugated tube 30, socket one in described corrugated tube 30 between described first union joint 10 and the second union joint 20
Instlated tubular 40, described instlated tubular 40 is mixed by asbestos and glass fibre, is also socketed a polrvinyl chloride in described instlated tubular 40
Plastic tube 50, described pvc tube 50 and instlated tubular 40 crimp for mechanical high-temperature.
Further improve as to this utility model, described corrugated tube 30 is double-wall corrugated pipe.
Further improve as to this utility model, the thickness of described pvc tube 50 and instlated tubular 40
Than for 2：7.
The cold tight pipeline intelligent new exclusive expansion joint of this utility model has been socketed a polychlorostyrene second in the inner side of corrugated tube
Alkene plastics pipe and an instlated tubular, instlated tubular can effectively stop cryogen infringement corrugated tube, pvc tube in pipe
The intensity of instlated tubular can be increased, this expansion joint at low ambient temperatures can be with life-time service.
Mentality of designing of the present utility model to be below only described in one embodiment, in the case that system allows,
This utility model can expand to simultaneously external more functional modules, thus extending its function to greatest extent.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, any change or replacement expected without creative work, all should cover within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be defined by the protection domain that claims are limited.
