Disclosure of Invention
The technical problem to be solved by the utility model is to provide the stainless steel expansion ring for repairing the underwater large-diameter GRP pipeline, which is designed into a spliced structure, so that on one hand, the operation difficulty of divers can be reduced, the connection and the assembly of operators are convenient, and meanwhile, the repair of the oversized pipe seam or the staggered seam at the joint of the GRP pipeline can be realized through the designed stainless steel expansion ring.
The technical scheme includes that the stainless steel expansion ring for repairing the underwater large-diameter GRP pipeline comprises a plurality of stainless steel expansion ring splicing pieces, bolt fasteners and rubber washers, wherein the stainless steel expansion ring splicing pieces are connected and fixed through the bolt fasteners to form a circular stainless steel expansion ring, and the rubber washers are arranged on the outer sides of the circumferences of the circular stainless steel expansion rings.
According to the scheme, the number of the stainless steel expansion ring splicing pieces is four, the stainless steel expansion ring splicing pieces are sequentially connected end to form the round stainless steel expansion ring, and the end to end connection positions of the stainless steel expansion ring splicing pieces are fixedly connected through the bolt fasteners.
According to the scheme, the bolt fastener comprises a fixed gasket and a fixed bolt, wherein the fixed gasket is arranged at the joint of the adjacent stainless steel expansion rings, and the fixed gasket is fixedly connected with the stainless steel expansion rings through the fixed bolt.
According to the scheme, the rubber gasket is arranged on the outer side of the circumference of the circular stainless steel expansion ring.
According to the scheme, the rubber gasket is annular, and two water stops are arranged on the back surface of the rubber gasket.
According to the scheme, the rubber gasket is made of chlorobutyl rubber.
The stainless steel expansion ring for repairing the underwater large-diameter GRP pipeline has the following beneficial effects:
The stainless steel expansion ring for repairing the underwater large-diameter GRP pipeline is designed into a spliced structure (spliced together through the stainless steel expansion ring splicing pieces), so that on one hand, the operation difficulty of divers can be reduced (because the volume and the mass of each stainless steel expansion ring splicing piece are smaller), the connection and the splicing of operators are convenient, meanwhile, the repair of the oversized pipe seam or the staggered seam at the GRP pipeline joint can be realized through the designed stainless steel expansion ring installed at the GRP pipeline joint, the oversized pipe seam or the staggered seam is plugged through the rubber gasket, and meanwhile, the sealing performance of the rubber gasket is enhanced because the two water stops at the back of the rubber gasket are clung to the inner wall of the GRP pipeline, so that the use effect of the GRP pipeline is ensured.
Drawings
The utility model will be further described with reference to the accompanying drawings and examples, in which:
FIG. 1 is a schematic diagram of the overall structure of a stainless steel expander for underwater large diameter GRP pipeline repair of the present utility model;
FIG. 2 is an enlarged schematic view of the portion A of FIG. 1 according to the present utility model;
In the figure, 1, a rubber gasket, 2, a stainless steel expansion ring bolt fastener, 2.1, a stainless steel expansion ring splicing piece, 2.2, a fixed gasket, 2.3, a fixed bolt, 3, a stainless steel expansion ring, 4 and a water stop belt.
Detailed Description
For a clearer understanding of technical features, objects and effects of the present utility model, a detailed description of embodiments of the present utility model will be made with reference to the accompanying drawings.
As shown in fig. 1 and 2, the stainless steel expansion ring for repairing the underwater large-diameter GRP pipeline comprises a plurality of stainless steel expansion ring splicing pieces 2.1, and the stainless steel expansion ring splicing pieces 2.1 are spliced together through stainless steel expansion ring bolt fasteners 2 to form a circular stainless steel expansion ring 3.
In the embodiment, four stainless steel expansion ring splicing pieces 2.1 are arranged, and the four stainless steel expansion ring splicing pieces 2.1 are sequentially connected and fixed end to end through stainless steel expansion ring bolt fasteners 2 to form a circular stainless steel expansion ring 3.
