Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of pipeline pair It connects circumferential weld and repairs sealing structure, can effectively solve the problems, such as that existing pipeline Butt sealing effect is bad.
To achieve the above object, the utility model is using following technical solution:
A kind of pipeline docking circumferential weld repairs sealing structure, include first pipe, second pipe, Polyurethane seals and Cement sand bed;There is an annular step surface, the front end of the second pipe to be inserted into the first pipe in the open rearward end of the first pipe In the open rearward end in road, it is formed with first annular clip slot between the front end circumferential lateral surface and first pipe of second pipe, this second The second annular clip slot is formed between the front end face and annular step surface of pipeline, the second annular clip slot connects with first annular clip slot It is logical;The Polyurethane seals are sheathed on the front end of second pipe, and Polyurethane seals include the sheath body portion for being integrally formed connection With thick ring portion, sheath body portion is located in first annular clip slot and is clamped between first pipe and second pipe, and thick ring portion is located at the In second ring clip slot, annular fever tablet is provided on the internal face of thick ring portion, the lead of annular fever tablet passes through sheath body portion outside It stretches out, and foaming layer is covered in annular fever tablet, hot melt adhesive layer is covered in the foaming layer, which is filled in the In second ring clip slot and cover foaming layer and hot melt adhesive layer.
Preferably, the internal face of the cement sand bed is concordant with the inner wall of first pipe and second pipe.
Preferably, the first pipe and second pipe are cement material.
The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology Known to scheme:
By the way that Polyurethane seals to be sheathed on to the front end of second pipe, and be equipped with annular fever tablet, foaming layer and Lead is connected power supply after docking and cement sand bed is arranged, so that annular fever tablet is generated heat, foaming layer by hot melt adhesive layer, pipeline Expanded by heating, and make hot melt adhesive layer melting, hot melt adhesive is squeezed using foaming layer, to form better seal structure, ensures pipe Without gas and liquid leakage at road docking.
More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair The utility model is described in detail:
