Description
Technical field
The utility model relates to a kind of auxiliary member of conveyance conduit external application, particularly relates to a kind of LNG gas station pipe insulation shell, belongs 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, the insulation pipe generally adopted for LNG gas station pipeline is shell insulation, and existing thermal-insulating pipe case, mainly contains two kinds, and one is cylindrical, in axial direction opens a breaking joint, during installation, is opened by thermal-insulating pipe case, wraps pipe and installs; Two is synthesize a circular tube shaped by two and half shells.Each mating face of these structures is plane, extremely easily makes mating face place occur gap, directly affect heat insulation effect during installation.The structure of these shells inevitably runs into the problem of " heat bridge ", and that is thermal radiation is by the outside radiations heat energy in the gap between shell and shell, causes heat loss, thus 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, the shell internal surface and the conveyance conduit that formed are that face contacts, and heat diffusion area is large, and heat insulation effect is bad, and certain heat insulation effect will be reached, just must increase the thickness of shell, this not only makes troubles to construction, too increases cost of production.
Model utility content
Main purpose of the present utility model is, overcomes deficiency of the prior art, provides a kind of LNG gas station pipe insulation shell of new structure, is specially adapted to carry out insulation protection to the conveyance conduit of LNG gas station.
Technical problem to be solved in the utility model is to provide simple, easy to operate, the practical LNG gas station pipe insulation shell of structure, not only can overcome the shortcoming of thermal radiation by the outside radiations heat energy in the gap between shell and shell, pin more heat energy indiffusion; And reduce the heat diffusion area of shell and conveyance conduit, improving its heat insulation effect does not but need to increase shell thickness, constructability, cost-saving, and has the value in industry.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of LNG gas station pipe insulation shell, comprise the shell body of hollow circuit cylinder body structure, described shell body comprises half consistent housing of two structures, and the internal surface of described half housing is that axial direction waveform shape is arranged; 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 with two groove size sizes of two and half housing homonymy groove match.
Adopt technique scheme, by changing the shape of shell internal surface, the internal surface of half housing is set to waveform shape, linear contact lay is become with between conveyance conduit after docking is installed, decrease the area of contact between shell inner surface and conveyance conduit, and define air chamber independent sealed one by one, thus when not increasing shell thickness, reduce heat diffusion area, ensure heat insulation effect; Meanwhile, shell body comprises half consistent housing of two structures, and structure is simple, easy for installation, is more importantly 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, fill with the packing with two and half housing homonymy groove match again, realize mating face and be planely changed to rectangular bent shape by original, cut off the thermal radiation of heat bridge, pin more heat, reach best heat insulation effect.The thermal-insulating pipe case of technique scheme, structure is simple, easy construction, does not increase other too much cost of production expenditure, can realize high-efficiency insulated reliably.
The utility model is set to further: the outer surface of described packing is provided with lock ring, described lock ring is connected with the rope part for being fixedly connected with by two and half housings.
The utility model 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, viscose glue lock seaming face can be selected and fix overall mode, also the mode that outer appliance fixes can be selected, such as adopt adhesive tape to carry out the fixation of circumference around formula to shell body outer surface, can certainly adopt simultaneously jointly fix in two ways.
But, there is the slow shortcoming of site operation progress in such fixing operation, so thermal-insulating pipe case of the present utility model, by being provided with lock ring on the cylindrical outer surface of half housing, on lock ring, the mode of connecting rope part carries out quick fixing operation, and structure is simple, constructability, solid and reliable; And dismounting is convenient and swift too, avoids using adhesive tape and bringing the problem half housing outer surface remaining the bad process of colloid later stage, improve the recycling rate of waterused of half housing, economize on resources.
The utility model is further set to: the circular arc top of the cylindrical outer surface of described half housing is provided with the fixing column for stationary rope part.
The utility model is further set to: described fixing column on the axial direction of half housing cylindrical outer surface in spaced apart, the layout pitch of described fixing column and the layout pitch of lock ring corresponding to the same.
The utility model is further set to: described rope part is tie wire.
In order to strengthen the shell body after installing docking, there is best solid and reliable performance, the circular arc top of the cylindrical outer surface of half housing is provided with fixing column, by the intermediate connection point that fixing column provides set to bind for the rope part on lock ring, make connection more solid and reliable, thus make the contact on mating face tightr further, guarantee high-efficiency insulated; Described rope part is preferably tie wire, constructability; More preferably zinc-plated steel wire, can avoid causing compromised quality to affect its soundness because Long-Time Service gets rusty.
In sum, a kind of LNG gas station of the utility model pipe insulation shell, has the advantage that structure is simple, easy to operate, practical, not only can pin more heat energy indiffusion, effectively be incubated; And the heat diffusion area of thermal-insulating pipe case and conveyance conduit is little, guarantee high-efficiency insulated further; 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.
