Description
Technical field
The utility model relates to LNG pipeline heat-insulating technology field, refers to a kind of thermal insulation pipe elbow and elbow Sealing especially.
Background technique
In order to production safety, the scene insulation of LNG gas station generally sets up polyurethane thermal pipe outside LNG pipeline, and polyurethane thermal pipe outer wrap has metal shell.The construction of thermal insulation pipe both can take the mode of foam-in-place, also can take the direct welding manner of prefabricated pipe.In general, in order to reduce site operation amount, improving efficiency of construction, better management and control site operation quality, usually adopting thermal insulation pipe form of construction work that is prefabricated in factory, Site Welding.But straight length can accomplish that prefabricated in factory, scene is directly welded, and elbow part then needs in-situ precast, cause site operation amount large, efficiency of construction is low, and site operation quality is not easy to management and control.
Model utility content
For solving above the deficiencies in the prior art, the utility model proposes a kind of structure simple, easy to use, effectively can reduce site operation amount during LNG pipe insulation process, improve the thermal insulation pipe elbow Sealing of efficiency of construction.
The technical solution of the utility model is achieved in that
A kind of thermal insulation pipe elbow Sealing, thermal insulation pipe elbow Sealing comprises elbow seal body, and elbow seal body is used for the weld seam of sealing thermal insulation pipe bend, and thermal insulation pipe elbow is welded by the first straight length and the second straight length,
Elbow seal body comprises 2 symmetrically arranged linkage structures, linkage structure comprises the first Sealing and the second Sealing, first Sealing is close to the first straight length pipe face and is arranged, second Sealing is close to the second straight length pipe face and is arranged, first Sealing and the second Sealing are formed in one structure, and the Sealing connecting line of the first Sealing and the second Sealing is close to weld seam and is arranged.
Preferably, elbow seal body inwall is provided with anti-slip veins.
Preferably, elbow seal body is metal seal or resin seal.
The utility model also proposes a kind of thermal insulation pipe elbow, be located at outside LNG pipeline, comprise: the metal shell be located at the polyurethane bend pipe outside LNG pipeline and be located at outside polyurethane bend pipe, polyurethane bend pipe is connected by above-mentioned thermal insulation pipe elbow Sealing with between metal shell.
The appearance of thermal insulation pipe elbow Sealing of the present utility model, significantly improves existing thermal insulation pipe elbow form of construction work, solves the problem that in prior art, thermal insulation pipe elbow site operation amount is large, efficiency of construction is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure: 11, the first straight length; 12, the second straight length; 2, elbow seal body; 21, the first Sealing; 22, the second Sealing; 23, Sealing connecting line.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1: a kind of thermal insulation pipe elbow Sealing, comprises elbow seal body 2, elbow seal body 2 is for the weld seam of sealing thermal insulation pipe bend, and thermal insulation pipe elbow is welded by the first straight length 11 and the second straight length 12,
Elbow seal body 2 comprises 2 symmetrically arranged linkage structures, and (2 linkage structure one end connect, the other end does not connect), linkage structure comprises the first Sealing 21 and the second Sealing 22, first Sealing 21 is close to the first straight length 11 pipe face and is arranged, second Sealing 22 is close to the second straight length 12 pipe face and is arranged, first Sealing 21 and the second Sealing 22 are formed in one structure, and the Sealing connecting line 23 of the first Sealing 21 and the second Sealing 22 is close to weld seam and is arranged.
As the preferred technological scheme of one, an embodiment more of the present utility model, elbow seal body 2 inwall is provided with anti-slip veins.Anti-slip veins be provided with the sealing effect helping improve elbow.
As the preferred technological scheme of one, another embodiment of the present utility model, elbow seal body 2 is metal seal or resin seal.
The thermal insulation pipe elbow Sealing that the utility model proposes, can be widely used in the isothermal holding of LNG bend pipe.Polyurethane thermal pipe outside LNG pipeline can be prefabricated in factory, the metal shell of parcel polyurethane thermal pipe adopts the mode of Linear cut prefabricated, when doing heat-preserving bent pipe, only need prefabricated polyurethane thermal pipe and metal shell to be located at by rivet or other Placement on the LNG pipeline of needs insulation, being finally fixedly connected with around the weld seam of the first straight length 11 and the second straight length 12, head and the tail by thermal insulation pipe elbow Sealing can (be fixedly connected with can take to weld, rivet interlacement or other suitable Placement) from beginning to end.
The thermal insulation pipe elbow Sealing that the utility model proposes effectively can reduce site operation amount during LNG pipe insulation process, improves efficiency of construction.
The utility model also proposes a kind of thermal insulation pipe elbow, be located at outside LNG pipeline, comprise: the metal shell be located at the polyurethane bend pipe outside LNG pipeline and be located at outside polyurethane bend pipe, polyurethane bend pipe is connected by above-mentioned thermal insulation pipe elbow Sealing with between metal shell.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
