Description
Technical field
The utility model relates to a kind of expansion bellow, more precisely, be a kind of external pressure axial corrosion-resistant thermal insulation type direct-burried
Expansion bellow.
Background technology
Expansion bellow can play what telescopic action mainly realized by bellows, to the function of expansion bellow and
Intensity Design is mainly design to bellows, different designs and the combination to bellows, can make bellows stretching, compression or
Bending, thus form the expansion bellow of three kinds of citation forms axial, horizontal, angular.
Expansion bellow the performing poor in terms of corrosion resistance and insulation that current industry commonly uses, thus significantly
Limit the range of expansion bellow.
Utility model content
The utility model is mainly the technical problem solving existing for prior art, thus provides a kind of axial anticorrosion of external pressure
Thermal-insulating type direct-burried expansion bellow.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of external pressure axial corrosion-resistant thermal insulation type direct-burried expansion bellow, comprises a bellows, and the two ends of described bellows are divided
It is not provided with one first connector and one second connector, described second connector can be provided with to precession a connecting tube, described company
Adapter is fixed by a clamp nut and the second connector, and described connecting tube is provided with external screw thread, connecting tube is additionally provided with one and lives
Dynamic nut, described bellows is double-decker, is filled with insulation material between double-decker.
As the utility model preferred embodiment, the surface of described bellows is sprayed with one layer of zinc.
As the utility model preferred embodiment, described the first connector, the second connector become with bellows one
Type.
Bellows on external pressure of the present utility model axial corrosion-resistant thermal insulation type direct-burried expansion bellow uses double-decker to set
Meter, is filled with insulation material between double-decker, and simultaneously the one layer of zinc of surface spraying at bellows, thus substantially increases
The heat-insulating property of this expansion bellow and corrosion resistance, expand its range, has wider array of application and more preferably economy
Benefit.
Brief description
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing of required use is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is 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 drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of external pressure of the present utility model axial corrosion-resistant thermal insulation type direct-burried expansion bellow；
Fig. 2 is the perspective view of the axial corrosion-resistant thermal insulation type direct-burried expansion bellow of the external pressure in Fig. 1, is now another
One visual angle.
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 external pressure axial corrosion-resistant thermal insulation type direct-burried expansion bellow 1, comprises a bellows 2, institute
That states bellows 2 is respectively arranged at two ends with one first connector 31 and one second connector 32, and described second connector 32 can revolve
Be provided with a connecting tube 51 with entering, described connecting tube 51 is fixed by a clamp nut 4 and the second connector 32, described connecting tube 51
Being provided with external screw thread, connecting tube 51 being additionally provided with a traveling nut 52, described bellows 2 is double-decker, fills out between double-decker
It is filled with insulation material.
Further improving as to the utility model, the surface of described bellows 2 is sprayed with one layer of zinc.
Further improve as to the utility model, the first described connector the 31st, the second connector 32 and ripple
Pipe 2 is one-body molded.
Bellows on the external pressure axial corrosion-resistant thermal insulation type direct-burried expansion bellow of this utility model uses double-decker to set
Meter, is filled with insulation material between double-decker, and simultaneously the one layer of zinc of surface spraying at bellows, thus substantially increases
The heat-insulating property of this expansion bellow and corrosion resistance, expand its range, has wider array of application and more preferably economy
Benefit.
Mentality of designing of the present utility model is below only described in one embodiment, in the case that system allows,
The utility model can expand to simultaneously external more functional module, thus extends its function to greatest extent.
The above, detailed description of the invention only 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 cover 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.
