Abstract
The utility model is specifically related to a kind of bushing type delivery pipe of improvement, comprise interior pipe and be set in the outer tube outside described interior pipe, the two ends of described outer tube are closed with described outer wall of inner tube and are connected, and the two ends of described outer tube are respectively arranged with connection mouth, and the middle part of described outer tube is made up of bellows.The phenomenon that the utility model not only can effectively avoid in use pipeline to be torn at weakness and to pull open, and save material; Reach protective conduit, reduce safeguard, the protective medium object of normally carrying.
Description
Technical field
The utility model is specifically related to a kind of bushing type delivery pipe.
Background technique
There is much liquid to pass through just can carry under certain temperature conditions in industrial production, otherwise be difficult to normal conveying, usually adopting companion's heat or cooling collar to carry out companion's heat or cool carrying to this type of delivery pipe for solving problems.Existing bushing type delivery pipe, its inner and outer tubes are light pipe mostly, have that structure is simple, easily manufactured, insulation or an advantage such as cold insulation is effective, obtain widely using of people.But this structural type is when passing into fluid, due to inside and outside medium temperature difference place, inner and outer tubes expand different, often torn from weakness by outer tube, pull open, affect the normal conveying of medium.
Model utility content
The purpose of this utility model is to provide a kind of bushing type delivery pipe that can effectively prevent pipe in using process from splitting.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of bushing type delivery pipe of improvement, comprise interior pipe and be set in the outer tube outside described interior pipe, the two ends of described outer tube are closed with described outer wall of inner tube and are connected, the two ends of described outer tube are respectively arranged with connection mouth, the middle part of described outer tube is made up of bellows, and the length of described bellows is one of percentage of casing length.
The beneficial effects of the utility model are:
The phenomenon that the utility model not only can effectively avoid in use pipeline to be torn at weakness and to pull open, and save material; Reach protective conduit, reduce safeguard, the protective medium object of normally carrying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, the outer tube 1 that the utility model comprises interior pipe 2 and is set in outside described interior pipe 2, the two ends of described outer tube 1 are connected with described interior pipe 2 closed front, the two ends of described outer tube 1 are respectively arranged with connection mouth 4, the middle part of described outer tube 1 is made up of bellows, and the length of this bellows 3 is one of percentage of casing length.
In use, in interior pipe 2, pass into the fluid needing conveying, in outer tube 1, pass into the liquid of insulation or cold insulation.Middle part due to outer tube 1 is most weakness, so be bellows structure in the middle part of the utility model, effectively prevent the phenomenon torn compared with senior general's pipeline at weakness or pull open due to the inner and outer pipe temperature difference; And the length working as bellows 3 is percent a period of time of casing length, can reach the phenomenon avoiding outer tube 1 to be torn or to pull open, also can save rapidoprint, reduce costs.
Claims (1)
1. the bushing type delivery pipe improved, comprise interior pipe (2) and be set in described interior pipe (2) outer tube outward (1), the two ends of described outer tube (1) are connected with described interior pipe (2) closed front, the two ends of described outer tube (1) are respectively arranged with connection mouth (4), it is characterized in that: the middle part of described outer tube (1) is made up of bellows (3), and the length of described bellows (3) is one of percentage of casing length.
