Description
Technical field
The present invention relates to a kind of auxiliary member of conveyance conduit external application, particularly relate to a kind of LNG gas station pipe insulation shell, belong to pipeline heat-insulating technology field.
Background technique
Insulation pipe is widely used in the transmission pipeline network of liquid, gas, and on insulation conveyance conduit, pipe insulation is a very important link, and can the success or not in this link be directly connected to this pipeline and formally come into operation.
At present, be shell insulation for the general insulation pipe adopting of LNG gas station pipeline, existing thermal-insulating pipe case, mainly contains two kinds, and the one, cylindrical, in axial direction open a breaking joint, when installation, thermal-insulating pipe case is opened, wrap pipe and install; The 2nd, by the synthetic circular tube shaped of two and half shells.Each mating face of these structures is plane, extremely easily makes mating face place occur gap when installation, directly affects heat insulation effect.The structure of these shells inevitably runs into the problem of " heat bridge ", that is to say that thermal radiation, by the outside radiations heat energy in the gap between shell and shell, causes heat loss, thereby affects heat insulation effect.
In addition, in the prior art, conveyance conduit general thermal-insulating pipe case used is made up of two and half shells of certain length, shell internal surface and the conveyance conduit forming is that face contacts, and heat diffusion area is large, and heat insulation effect is bad, and to reach certain heat insulation effect, the thickness that just must increase shell, this not only makes troubles to construction, has also increased cost of production.
Summary of the invention
Main purpose of the present invention is, overcomes deficiency of the prior art, and a kind of LNG gas station pipe insulation shell is provided, and is specially adapted to the conveyance conduit of LNG gas station to be incubated protection.
Technical problem to be solved by this invention is to provide simple in structure, easy to operate, practical LNG gas station pipe insulation shell, not only can overcome thermal radiation by the shortcoming of the outside radiations heat energy in gap between shell and shell, pin more heat energy indiffusion; And the heat diffusion area of minimizing shell and conveyance conduit, improving its heat insulation effect does not but need to increase shell thickness, and constructability is cost-saving, and has the value in industry.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of LNG gas station pipe insulation shell, comprises the shell body of hollow circuit cylinder body structure, and described shell body comprises two half housings that structure is consistent, and the internal surface of described half housing is the setting of axial direction waveform shape; The outboard end of described half housing both ends of the surface is provided with groove; Also comprise packing, described packing is the list structure of the two groove size sizes that match with two and half housing homonymy grooves.
Adopt technique scheme, by changing the shape of shell internal surface, the internal surface of half housing is set to waveform shape, after docking is installed and between conveyance conduit, become line to contact, reduce the area of contact between shell inner surface and conveyance conduit, and formed independent sealed one by one air chamber, thereby do not increase shell thickness in the situation that, reduce heat diffusion area, ensure heat insulation effect; Meanwhile, shell body comprises two half housings that structure is consistent, simple in structure, easy for installation, and main is to be convenient to manufacture, and only needs die sinking a kind of, reduces cost of production; In addition, change the end-face structure of half housing, the outboard end of half housing both ends of the surface is all arranged to groove structure, use again the packing matching with two and half housing homonymy grooves to fill, realize mating face by the original plane rectangular bent shape that is changed to, cut off the thermal radiation of heat bridge, pin more heat, reach best heat insulation effect.The thermal-insulating pipe case of technique scheme, simple in structure, easy construction, does not increase other too much cost of production expenditures, can realize high-efficiency insulated reliably.
The present invention is further set to: on the outer surface of described packing, be provided with lock ring, be connected with the rope part for two and half housings are fixedly connected with on described lock ring.
The present invention is further set to: described lock ring is spaced apart on the axial direction of packing outer surface.
Two and half housings are mounted to hollow circular cylinder shell body, can select viscose glue lock seaming face and fix overall mode, also the mode that can select outer appliance to fix, such as adopting adhesive tape to carry out the fixation of circumference around formula to this external surface of shell, can certainly adopt in two ways and jointly fix simultaneously.
But, there is the slow shortcoming of site operation progress in such fixing operation, thus thermal-insulating pipe case of the present invention, by being provided with lock ring on the cylindrical outer surface at half housing, on lock ring, the mode of connecting rope part is carried out quick fixing operation, simple in structure, constructability, solid and reliable; And dismounting is convenient and swift too, avoid using adhesive tape and bring the problem that remains the bad processing of colloid later stage in half housing outer surface, improve the recycling rate of waterused of half housing, economize on resources.
The present invention is further set to: on the circular arc top of the cylindrical outer surface of described half housing, be provided with the fixing column for stationary rope part.
The present invention is further set to: described fixing column is spaced apart on the axial direction of half housing cylindrical outer surface, and the distribution interval of described fixing column and the distribution interval of lock ring are corresponding to the same.
The present invention is further set to: described rope part is tie wire.
There is best solid and reliable performance in order to strengthen the shell body of installing after docking, on the circular arc top of the cylindrical outer surface of half housing, be provided with fixing column, the intermediate connection point that provides set to bind for the rope part on lock ring by fixing column, make to connect more solid and reliable, thereby further make the contact on mating face tightr, guarantee high-efficiency insulated; Described rope part is preferably tie wire, constructability; More preferably zinc-plated steel wire, can avoid getting rusty and causing compromised quality to affect its soundness because of long-term use.
In sum, a kind of LNG of the present invention gas station pipe insulation shell, has advantages of simple in structure, easy to operate, practically, not only can pin more heat energy indiffusion, effectively insulation; And the heat diffusion area of thermal-insulating pipe case and conveyance conduit is little, further guarantee high-efficiency insulated; Dismounting is simultaneously convenient quick, and constructing operation difficulty is low, and firm reliability is good, and the cost of production of thermal-insulating pipe case is also low.
