Further, the second annulus outer wall is fixed with several convex blocks, and second pipe inner wall is fixed with several limited blocks, limit Block offers and the groove of corresponding convex block cooperation.

By adopting the above technical scheme, first the first annulus is fixed in first pipe, and abut bar and the first annulus and Second annulus is fixed, and then second pipe is sheathed in first pipe, at the same convex block with groove not in the same of first pipe On length direction, when convex block face groove, rotation second pipe makes convex block be caught in groove, to realize first pipe and the The detachable installation of two pipelines.

Further, first pipe outer wall is provided with the first prompt item along the setting of first pipe length direction, the second pipe Pipeline outer wall is provided with the first prompt item cooperation to prompt the second of groove and bump position to prompt item.

By adopting the above technical scheme, by the first display item of setting and the second display item, consequently facilitating staff Solve the relative position of convex block and groove.

Further, the length for abutting bar is 10-30mm.

By adopting the above technical scheme, the length for abutting bar is set as 10-30mm, the i.e. inner wall and first pipe of second pipe The distance between outer wall be 10-30mm, not only there is cavity, also save taking up space for the Anti-freezing pipeline.

Further, the inner wall of second pipe is provided with thermal insulation layer.

By adopting the above technical scheme, by the way that thermal insulation layer is arranged, to reduce ambient temperature to second pipe internal temperature It influences.

Further, the outer wall of second pipe is provided with antirust coat and ultraviolet resistant layer, and antirust coat is set to UV resistance Between line layer and first pipe.

By adopting the above technical scheme, by the way that antirust coat is arranged, the probability that second pipe outer wall gets rusty is reduced, is prevented by being arranged Ultra-violet layer, to reduce radiation injury of the ultraviolet light to pipeline and antirust coat.

Further, the length of second pipe is set as 2-10m.

By adopting the above technical scheme, 2-10m is set by the length of first pipe, consequently facilitating to the peace of second pipe Dress.

Compared with prior art, the utility model has the advantages that:

(1) by the way that second pipe is arranged outside first pipe, to make between first pipe outer wall and second pipe inner wall A cavity is formed, in weather cold, first pipe is made to be isolated from the outside, a protective effect is played to first pipe, moreover it is possible to is logical Steam generating device is crossed to empty intra-bladder instillation steam, reduces first pipe icing or freezing probability；

(2) it improves and connects between first pipe and second pipe to support abutting bar by the first annulus of setting, the second annulus The stability connect.
