Abstract
Provided is a pipeline compensation structure for a cryogenic vessel. The pipeline compensation structure for the cryogenic vessel comprises an outer vessel wall, a vessel internal pipeline and a vessel external pipeline, wherein one end of the vessel internal pipeline is fixedly connected with a vacuum pipe, the other end of the vacuum pipe and the outer vessel wall are in clearance fit, the other end of the vacuum pipe is fixedly connected with the vessel external pipeline, one end of an expansion joint is fixedly connected with the outer vessel wall, and the other end of the expansion joint is fixedly connected with a connecting flange on the vessel external pipeline. The pipeline compensation structure for the cryogenic vessel is used for the structure that technical pipelines of the double-shell cryogenic vessel enter and go out of an external vessel is adopted, wherein an internal vessel of the double-shell cryogenic vessel is a cryogenic vessel body, and the external vessel of the double-shell cryogenic vessel is a normal-temperature vessel. The vacuum pipe and thermal insulating materials are used for preventing heat transfer between the inside and the outside of the position where the technical pipelines enter and go out of the cryogenic vessel, the expansion joint is used for compensating the displacement, caused by cold contraction, of the pipelines, and the displacement, caused by cold contraction, of the internal vessel, and the pipeline compensation structure for the cryogenic vessel is simple in structure, convenient to construct and capable of being widely used.
Description
Technical field
The utility model relates to a kind of low-temperature (low temperature) vessel, and being specifically related to a kind of inner canister that is applicable to is that low-temperature (low temperature) vessel, outer tank are the pipeline collocation structures of the bivalve low-temperature (low temperature) vessel that is used for storage low temperature liquid hydro carbons, liquified natural gas, liquid oxygen, liquid argon and liquid nitrogen of cold chamber.
Background technique
Progress and industrial expansion along with science and technology, be used for the storing liquid hydro carbons, liquified natural gas, liquid oxygen, the bivalve low-temperature (low temperature) vessel of liquid argon and liquid nitrogen is more and more, the demand of its process pipelines is more and more, all be that process pipelines directly is connected with outer tank skin with structure now, because the cryogenic media of interior tank stores, pipeline outside tank skin joint has produced larger temperature stress and displacement stress, and then affected the safe operation of storage tank, this place does not arrange insulation simultaneously, the leakage heat of pipeline is serious, aggravate the day evaporation loss of storage tank, increased the regular job maintenance cost of storage tank.
The model utility content
The utility model provide a kind of can low-temperature (low temperature) vessel pipeline collocation structure heat insulation, effectively absorption tube linear displacement.
For achieving the above object, solution of the present utility model is: a kind of low-temperature (low temperature) vessel pipeline collocation structure, comprise that outer tank tank skin and tank are interior, the tank external pipeline, one end and the vacuum tube of described tank gut line are affixed, and be affixed with described tank external pipeline after the other end of this vacuum tube and the described outer tank tank skin Spielpassung; Expansion joint one end and described outer tank tank skin are affixed, the other end and place the adpting flange on the described tank external pipeline affixed.
Filling heat insulator between described vacuum tube and the expansion joint.
It is that low-temperature (low temperature) vessel, outer tank are the structures of process pipelines turnover outer tank of the bivalve low-temperature (low temperature) vessel of cold chamber that the utility model is used for inner canister, adopt vacuum tube and thermoinsulation material to cut off the process pipelines turnover inside and outside heat transmission in low-temperature (low temperature) vessel place, adopt expansion joint compensation pipes and inner canister because the displacement amount that shrinkage produces, the utility model is simple in structure, the construction aspect can be widely used.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Following structure accompanying drawing is described in further detail the utility model.
With reference to Fig. 1, a kind of low-temperature (low temperature) vessel pipeline collocation structure comprises that outer tank tank skin 3 and tank are interior, tank external pipeline 1,7, one end and the vacuum tube 2 of described tank gut line 1 are affixed, after the other end of this vacuum tube 2 and described outer tank tank skin 3 Spielpassung and described tank external pipeline 7 affixed; Expansion joint 4 one ends and described outer tank tank skin 3 are affixed, the other end and place the adpting flange 6 on the described tank external pipeline 7 affixed.The Spielpassung of vacuum tube 2 and outer tank tank skin 3 is so that in the tank, when contraction or elongation strain appear in tank external pipeline 1,7, vacuum tube 2 can be freely movable, displacement absorbs by expansion joint 4, can avoid like this vacuum tube 2 and outer tank tank skin 3 directly to be connected the excessive problem of localized stress that produces.
Filling heat insulator 5 between described vacuum tube 2 and the expansion joint 4.Be used for the intercept heat conduction, reduce the heat loss of joint.
Claims (2)
1. low-temperature (low temperature) vessel pipeline collocation structure, comprise that outer tank tank skin and tank are interior, the tank external pipeline, it is characterized in that: an end of described tank gut line (1) and vacuum tube (2) are affixed, and be affixed with described tank external pipeline (7) after the other end of this vacuum tube (2) and described outer tank tank skin (3) Spielpassung; Expansion joint (4) one ends and described outer tank tank skin (3) are affixed, the other end and place the adpting flange (6) on the described tank external pipeline (7) affixed.
2. a kind of low-temperature (low temperature) vessel pipeline collocation structure according to claim 1 is characterized in that: filling heat insulator (5) between described vacuum tube (2) and the expansion joint (4).
