Referring to fig. 1-4, in the present embodiment, a composite material anti-corrosion compensator includes connection pipes 1 and a compensator body 2 disposed between the connection pipes 1:

a guard mechanism 3 including a guard portion 31 and a fixing portion 32, wherein,

the protection part 31 is arranged between the connecting pipes 1, is attached to the inner surface of the compensator body 2, forms a lining through the protection part 31 to cover the inner wall of the compensator body 2, and improves the corrosion resistance of the compensator body 2;

the fixing portion 32 includes a limiting member 321 disposed on the connection pipe 1 and the protection portion 31, and a sealing member 322 disposed between the limiting member 321 and the protection portion 31, and is matched with the sealing member 322 through the limiting member 321, so that when the connection pipe 1 is completed, the compensator body 2 is sealed and isolated, and the corrosion resistance of the compensator body 2 is improved.

Based on the above embodiment, the protection portion 31 is preferably a plastic protection layer, the plastic protection layer is made of teflon, the protection portion 31 covers the inner wall of the compensator body 2, and one end of the protection portion 31, which enters the adapter tube 1, is annular, so the limiting member 321 is an annular stainless steel plate, and the cross section of the limiting member 321 is L-shaped, and can just correspond to the protection portion 31, so that the limiting member 321 and the adapter tube 1 can extend into the protection portion 31, and finally the sealing member 322 is filled, the protection layer 31 is compacted and welded on the adapter tube 1, the sealing member 322 is used for improving the sealing performance between the limiting member 321 and the protection layer 31, and the sealing member 322 is preferably a high-temperature sealant.

Referring to fig. 1-4, one end of the compensator body 2 extending to the adapter tube 1 is located between the protection part 31 and the adapter tube 1, the protection part 31 corresponds to the compensator body 2, one end of the limiting part 321 is disposed on the inner wall of the adapter tube 1, the other end extends into the protection part 31, an indirect connection is left between the limiting part 321 and the protection part 31, and the sealing element 322 is disposed in the gap.

In the embodiment, two ends of the compensator body 2 are inserted into the connecting pipe 1 for pipeline compensation, when the protection part 31 is arranged, after the protection part 31 covers the inner wall of the compensator body 2, the two ends of the compensator body 2 continuously extend towards the inside of the connecting pipe 1, the compensator body 2 and the connecting pipe 1 are connected and simultaneously covered, and the corrosion resistance of the inner wall of the compensator body 2 is further improved;

when the protection part 31 is fixed, the limit part 321 is adopted to press the protection part 31 on the adapter tube 1, and meanwhile, the sealing part 322 is added between the protection part and the adapter tube, so that the limit effect of the limit part 321 on the protection part 31 is improved, and the sealing performance of the protection layer 31, the limit part 321 and the adapter tube 1 can be improved.

Referring to fig. 1 to 4, a protection assembly 4 is disposed between the compensator body 2 and the connection pipe 1, one end of the protection assembly 4 is connected to the compensator body 2 through a bolt, the protection assembly 4 includes an upper protection plate 41 and a lower protection plate 42 disposed outside the compensator body 2, and the upper protection plate 41 and the lower protection plate 42 are disposed in an aligned manner.

When compensator body 2 uses, because the setting of inserting is inserted to 2 link ends of compensator body, compensator body 2 can contact with takeover 1 near the portion of bending of takeover 1 in the compensation process to cause compensator body 2 and takeover 1 kneck wearing and tearing, make the damage of wearing and tearing department aggravate in external factor very easily.

Based on the consideration, the compensator body 2 is provided with the bolt, the protection component 4 is butted on the bolt, and then the nut is screwed to fix the protection component 4, so that the protection component 4 is connected with the compensator body 2 and covers the connecting pipe 1, and the connection protection of the compensator body 2 and the connecting pipe 1 is realized;

and after takeover 1 and compensator body 2 are connected, they can constitute a whole, and it is inconvenient like this to enclose protection component 4 on takeover 1, consequently adopt split type upper shield 41 and protection shield 42 installation down, can make things convenient for the staff to assemble respectively, encircle between compensator body 2 and takeover 1 after the equipment.

Further, the other ends of the upper protection plate 41 and the lower protection plate 42 are abutted to the adapter tube 1, one side of the upper protection plate 41 opposite to the lower protection plate 42 is provided with an outer bending part, one side of the lower protection plate 42 opposite to the upper protection plate 41 is provided with an inner bending part, and the inner bending part corresponds to the outer bending part.

Because when compensator body 2 compensated deformation, divided circumstances appears in last protection shield 41 and lower protection shield 42 meeting follow-up, and then makes takeover 1 directly expose outside with compensator body 2 junction, consequently through the portion of bending in protection shield 42 under the cooperation of the portion of bending of going up 41, like this when last protection shield 41 separates with lower protection shield 42, the portion of bending outward still can hide including connecting portion with the portion of bending follow-up separation in.

Based on the above-mentioned outside portion of bending orientation is kept away from the direction slope of taking over 1, and the portion of bending is the V-arrangement in, and the one end of keeping away from lower protection shield 42 is parallel with the portion of bending outward, at last protection shield 41 with down the protection shield 42 constitute the back, outside portion of bending keep off in the portion of bending, will correspond the position take over 1 and compensator body 2 and hide.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
