Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, for the utility model discloses a thermal insulation structure of corrugated compensator, including bellows 1 and connect the port at bellows 1 both ends and take over 2, the port is taken over 2 and is heat supply pipeline's main part, is linked together with bellows 1, and bellows 1 sets up between two port takeovers 2. The corrugated pipe 1 is coaxially provided with a heat preservation support 3, two ends of the heat preservation support 3 are respectively welded on the port connecting pipe 2, and the heat preservation support 3 is made of aluminum alloy. The heat preservation support 3 is also sequentially provided with a galvanized steel wire mesh 4, a glass wool layer 5 and a heat preservation outer pipe 6. The thermal insulation outer pipe 6 is also welded on the port connecting pipe 2. Rock wool wraps the inner side and the outer side of the heat-preservation outer pipe 6. The galvanized steel wire mesh 4 can play a role in resisting moisture and preserving heat, the influence of expansion with heat and contraction with cold on the internal corrugated pipe 1 can be reduced, and on the other hand, the galvanized steel wire mesh 4 has stronger toughness, and the strength of the heat preservation support 3 can be effectively increased; the glass wool layer 5 has the function of heat preservation, reduces the deformation amount of the corrugated pipe 1 caused by expansion with heat and contraction with cold, and has longer service life.

Referring to fig. 1 and 3, in order to improve the installation stability of the galvanized steel wire mesh 4, a plurality of convex columns 7 which are matched with the galvanized steel wire mesh 4 in a clamping manner are arranged on the circumferential side surface of the heat preservation support 3 in a rectangular array mode, and one ends, close to the heat preservation support 3, of the convex columns 7 are provided with clamping grooves 71 in an inwards concave mode. Because the metal net inlay card of galvanized steel wire net 4 is in draw-in groove 71 for galvanized steel wire net 4 stably twines on heat preservation support 3, improves the stability of galvanized steel wire net 4 installation, and galvanized steel wire net 4 twines all the time on heat preservation support 3, thereby plays damp-proof heat retaining effect.

Referring to fig. 1 and 3, the convex column 7 sequentially penetrates through the galvanized steel wire mesh 4 and the glass wool layer 5, and one end of the convex column 7 penetrating through the glass wool layer 5 is abutted against the inner circumferential side wall of the heat-insulating outer pipe 6. The convex column 7 also plays a role of supporting the heat preservation outer pipe 6, and the inner corrugated pipe 1 is protected from deformation under pressure, so that the strength of the whole structure is improved. One end of the convex column 7 penetrating through the glass wool layer 5 is connected with a convex block 8 with a semicircular section. When the corrugated pipe 1 expands with heat and contracts with cold to generate displacement, the heat-insulating support 3 also displaces along with the heat-insulating support, the convex block 8 always abuts against the heat-insulating outer pipe 6 in the process that the convex block 7 moves, the semicircular convex block 8 reduces the contact area between the top end of the convex block 7 and the heat-insulating outer pipe 6, and the abrasion of the top end of the convex block 7 is reduced. In order to further prolong the service life of the convex column 7, the surface of the convex block 8 is coated with a rubber pad.

The implementation principle of the embodiment is as follows: the galvanized steel wire mesh 4 can play a role in resisting moisture and preserving heat, the temperature difference between two sides of the corrugated compensator is reduced, the influence of expansion with heat and contraction with cold on the internal corrugated pipe 1 is reduced, and on the other hand, the galvanized steel wire mesh 4 has stronger toughness and can effectively increase the strength of the heat preservation support 3; the glass wool layer 5 has the function of heat preservation, reduces the deformation amount of the corrugated pipe 1 caused by expansion with heat and contraction with cold, and has longer service life.

Because the metal net inlay card of galvanized steel wire net 4 is in draw-in groove 71 for galvanized steel wire net 4 stably twines on heat preservation support 3, improves the stability of galvanized steel wire net 4 installation, and galvanized steel wire net 4 twines all the time on heat preservation support 3, thereby plays damp-proof heat retaining effect.
