Description

Outer pipe connecting structure of prefabricated heat preservation pipes
Technical Field
The utility model relates to the technical field of pipelines, especially, relate to kinds of prefabricated insulating tube's outer tube connection structure.
Background
The prefabricated overhead heat-insulating pipe is a short-term heat-insulating pipeline, is used for conveying liquid, gas and other media, and is used for heat insulation engineering of pipelines of petroleum, chemical engineering, aerospace, hot spring-military, central heating, central air conditioning, municipal administration and the like. The structure of the existing heat preservation pipe is generally realized by adopting a three-layer structure of a working pipe, a heat preservation layer and an outer protection pipe, wherein the heat preservation layer is positioned between the working pipe and the outer protection pipe. The outer protective sleeve of the prefabricated overhead heat-insulating pipe is in a connecting structure for protecting the heat-insulating layer outside the heat-insulating layer, if the prefabricated overhead heat-insulating pipe is not well butted in installation, the heat-insulating layer cannot be completely sealed, so that the heat-insulating layer is partially exposed, the heat-insulating layer is in long-term contact with the outside, the heat-insulating effect is affected, and the heat-insulating pipe cannot be assembled and installed on site, and therefore needs to be improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an outer tube connecting structure of kinds of prefabricated insulating tubes to the technical defect who exists among the prior art.
For realizing the utility model discloses a technical scheme that the purpose adopted is:
kind of prefabricated insulating tube's outer tube connecting structure, including annular connecting portion and second annular connecting portion, annular connecting portion are used for fixing respectively on two prefabricated built on stilts insulating tube that will connect with second annular connecting portion, be connected and lock end with the nut through a plurality of evenly arranged's screw rods between annular connecting portion and the second annular connecting portion, every install the spring on the screw rod, the both ends of spring with the medial surface of annular connecting portion and second annular connecting portion contacts.
Preferably, the th annular connecting part and the second annular connecting part are respectively welded and fixed on two prefabricated overhead heat-insulating pipes to be connected.
Preferably, a blocking sleeve is sleeved on the butt joint between the two prefabricated overhead heat-insulating pipes to be connected so as to separate the butt joint from the outside.
Preferably, the number of the screws is 3-4.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses prefabricated insulating tube's outer tube connecting structure through pillar fixed connection portion outside, utilizes the connecting portion to couple together two outer pillar between the insulating tube, when having realized sealed effectual, and connect conveniently, quick.
Drawings
Fig. 1 is a schematic view showing an outer pipe connection structure of a prefabricated insulation pipe.
Fig. 2 is a schematic structural diagram of a prefabricated heat-insulating pipe.
Figure 3 shows a schematic view of the connection ring.
Detailed Description
The invention is described in further detail in with reference to the drawings and the following detailed description, it being understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, the utility model discloses kinds of prefabricated insulating tube's outer tube connecting structure, including annular connecting portion 4 and second annular connecting portion (the structure of this second annular connecting portion is the same with the structure of annular connecting portion, no longer marks on the picture), annular connecting portion and second annular connecting portion are used for fixing respectively on two prefabricated built on stilts insulating tube 1 that will connect, and the structure of prefabricated built on stilts insulating tube is interior work pipe 10, steel outer pillar 1 and is located insulating structure layer 9 between them, be connected through a plurality of evenly arranged screw rods 2 between annular connecting portion and the second annular connecting portion and lock at end with nut 5, every install spring 3 on the screw rod, the both ends of spring with the medial surface of annular connecting portion and second annular connecting portion contacts.
Preferably, the th annular connecting part and the second annular connecting part are respectively welded and fixed on two prefabricated overhead heat-insulating pipes to be connected, and a plurality of screw holes 8 which are uniformly and annularly arranged around the hole centers of the th annular connecting part and the second annular connecting part are formed on the th annular connecting part and the second annular connecting part.
Preferably, the stop sleeve 7 is sleeved on the butt joint between the two prefabricated overhead heat-insulation pipes to be connected so as to separate the butt joint 6 from the outside, so as to prevent water vapor such as external rainwater and the like from entering and influence the heat-insulation effect of the heat-insulation layer, wherein the stop sleeve 7 is sleeved on prefabricated overhead heat-insulation pipes in a prefabricated manner, after the two prefabricated overhead heat-insulation pipes are butted and fixed, the two prefabricated overhead heat-insulation pipes are directly pulled to cover the butt joint, and an elastic sleeve can be adopted to realize tight contact with the butt joint or a non-elastic interference contact matching sleeve, and the method is not limited in particular.
Preferably, the number of the screws 2 is 3-4, or a plurality of screws may be provided, and the number is not limited.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses prefabricated insulating tube's outer tube connecting structure through pillar fixed connection portion outside, utilizes the connecting portion to couple together two outer pillar between the insulating tube, when having realized sealed effectual, and connect conveniently, quick.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
