Abstract
The utility model discloses a glass fiber reinforced plastic supporting structure for a vacuum pipeline. The glass fiber reinforced plastic supporting structure comprises an outer pipe of the vacuum pipeline, an inner pipe of the vacuum pipeline and glass fiber reinforced plastic, wherein the glass fiber reinforced plastic is arranged between the outer pipe and the inner pipe and connected with and supported against the outer pipe and the inner pipe. The glass fiber reinforced plastic supporting structure is characterized in that point contact is achieved at the joint of the glass fiber reinforced plastic and the outer pipe and the joint of the glass fiber reinforced plastic and the inner pipe. The glass fiber reinforced plastic supporting structure is connected with and supported against the outer pipe of the vacuum pipeline and the inner pipe of the vacuum pipeline in a point contact mode, and therefore steam loss produced in the transmission process of low-temperature liquefied gas can be effectively reduced, and the heat preservation effect is better.
Description
Technical field
The utility model structure relates to a kind of vacuum and low temperature pipeline glass reinforced plastic support, a kind of vacuum and low temperature pipeline glass reinforced plastic support structure of using in particular for low temperature gas station transmission cryogenic liquide.
Background technique
The liquefied gas at low temp such as liquid oxygen, liquid nitrogen and LNG Liquefied natural gas are mainly carried by vacuum low-temperature heat insulation tube, and in long using process, along with the loss of degree of vacuum, the support between the vacuum inner and outer pipes is the serious position of cold damage herein.For meeting having of vacuum low-temperature heat insulation tube good cold insulation effect and service life, inside and outside pipeline support and connection are just particularly important.
As shown in Fig. 3～Fig. 4: in existing practice, all adopt the ring glass steel to support pattern, be and adopt a ring flat-plate that inside and outside pipeline is connected to form to an integral body, in use, low temperature can be passed to rapidly outer tube-surface by ring flat-plate, thereby reduce the cold of vacuum tube inside, increase vacuum low-temperature heat insulation tube evaporation loss.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can reduces vacuum pipe glass reinforced plastic support structure evaporation loss, that have better heat insulation effect.
For realizing above-mentioned model utility purpose, the utility model has adopted following technological scheme:
A kind of vacuum pipe glass reinforced plastic support structure, the outer tube, inner tube and the glass fibre reinforced plastics that comprise vacuum pipe, described glass fibre reinforced plastics is located between outer tube and inner tube and is connected and is supported in outer tube and inner tube, it is characterized in that, described glass fibre reinforced plastics contacts for point with the joint of outer tube and inner tube.
Preferably, the crest shape that described glass fibre reinforced plastics is arc, the upper summit of crest is connected in outer tube, and two lower extreme points of crest are connected in inner tube.
Preferably, described glass fibre reinforced plastics straight line is connected in outer tube and inner tube.
The model utility advantage:
Vacuum pipe described in the utility model adopts the mode of some contact to connect outer tube and the inner tube that supports vacuum pipe by the glass reinforced plastic support structure, can effectively reduce the evaporation loss of liquefied gas at low temp when transmission, makes better heat preservation.

The A-A that Fig. 2 is Fig. 1 is to sectional drawing;
Fig. 3 is the structural representation of prior art vacuum pipe by the glass reinforced plastic support structure;
The A-A that Fig. 4 is Fig. 3 is to sectional drawing.
Wherein, 1, outer tube; 2, inner tube; 3, glass fibre reinforced plastics.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the technical solution of the utility model is further described.
Embodiment:
A kind of vacuum pipe glass reinforced plastic support structure, the outer tube 1, inner tube 2 and the glass fibre reinforced plastics 3 that comprise vacuum pipe, described glass fibre reinforced plastics 3 is located between outer tube 1 and inner tube 2 and is connected and is supported in outer tube 1 and inner tube 2, and described glass fibre reinforced plastics 3 contacts for point with the joint of outer tube 1 and inner tube 2.
As shown in Fig. 1～Fig. 2: in a preferred embodiment of the present utility model, the crest shape that described glass fibre reinforced plastics 3 is arc, the upper summit of crest is connected in outer tube 1, and two lower extreme points of crest are connected in inner tube 2.
In another preferred embodiment of the present utility model, described glass fibre reinforced plastics 3 straight lines are connected in outer tube 1 and inner tube 2.
Glass fibre reinforced plastics 3 adopts the mode of some contact to connect outer tube 1 and the inner tube 2 that supports vacuum pipe, can effectively reduce the evaporation loss of liquefied gas at low temp when transmission, makes better heat preservation.
It is to be noted; as described above is only in order to explain the preferred embodiment of the utility model; not attempt is done any formal restriction to the utility model according to this; be with; all any modification or changes that the relevant the utility model of doing under identical model utility spirit is arranged, all must be included in the category that the utility model is intended to protection.
