Description
Technical field
The utility model belongs to the improvement of socket joint steel pipe fit structure, particularly a kind of socket joint steel pipe fit structure.
Background technology
Domestic existing socket joint steel pipe has three kinds of forms, and one kind is imitative spheroidal graphite cast-iron form of tubes, and second is that double indents protrude
Steel pipe internal-surface form, the third is to use Type of Welding after the roller edge rolling of rolled-section three.External common socket joint steel pipe is single indent
Form concordant with steel pipe inner wall.Wherein imitative spheroidal graphite cast-iron form of tubes, feature：Bellmouth roll-forming, socket necking forming, is suitable for
10mm and following steel pipe, because sealing ring shape matching is special, every circle has two kinds of different shore hardnesses, and the bigger cost of caliber is more
It is high；Double indents protrude steel pipe internal-surface form socket joint steel pipe, feature：Bellmouth flare formation, socket roll-forming, socket groove are higher than
Steel pipe inner wall, there is water resistance during actual use.Rolled-section socket joint steel pipe, feature：Enlarging after bellmouth strip edge rolling, is welded on bellmouth
On steel pipe；Socket strip uses shaped-steel strip, is welded on after edge rolling on socket steel pipe, inwall is more smooth.Bellmouth and socket are both needed to
It is welded on after sizing on steel pipe, low production efficiency.U.S.'s AWWA C200-12 standard socket joint steel pipes, feature：Bellmouth steel pipe and insert
Mouthful steel pipe is both needed to enlarging, and socket steel pipe need to connect two to three steel pipes in enlarging rear pressure slot when shortcoming is pressure testing, both ends are shut,
Suppress, take long after filling water.
Utility model content
The purpose of this utility model is to provide a kind of improved socket joint steel pipe fit structure, and its is rational in infrastructure, Ji Nengman
Water resistance small requirement during sufficient water flowing, and can enough realize the pressure testing before facilitating manufacturing inspection and live water filling, reduce pressure testing cost,
Quick pressing is realized, can be pinpointed the problems in time.
What the purpose of this utility model was realized in：A kind of improved socket joint steel pipe fit structure, the one of socket steel pipe
End sets socket enlarging, and double indents are set on socket enlarging wall, coordinates in double indents and is installed with sealing ring, its
In the back side diameters of double indents be more than or equal to the internal diameter of steel pipe, the socket enlarging of socket steel pipe and the bellmouth enlarging of bellmouth steel pipe
It is engaged, sealing ring is engaged with the bellmouth enlarging inwall of bellmouth steel pipe, between double indents at socket steel pipe socket enlarging
Water filling port is set on bellmouth steel pipe bellmouth enlarging wall.
Major design content is as follows：
The double flute form that the utility model combines American Standard and other domestic socket joint steel pipes are commonly used, when can meet water flowing
The small requirement of water resistance, and can enough realize inexpensive pressure testing, sealing ring in place after water injection hole among two sealing rings add about
500ml water can test steel pipe sealing situation, facilitate the pressure testing before manufacturing inspection and live water filling, can reduce pressure testing cost.
The utility model is rational in infrastructure, can meet water resistance small requirement during water flowing, and and can enough realizes convenient manufacture inspection
Test with the pressure testing before live water filling, reduce pressure testing cost, realize Quick pressing, be found that problem in time.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model front view structure
Figure.
Embodiment
A kind of improved socket joint steel pipe fit structure, as shown in figure 1, one end of socket steel pipe 2 sets socket enlarging, and
And double indents 3 are set on socket enlarging wall, coordinate in double indents 3 and sealing ring 4 is installed, wherein the back side of double indents 3
Diameter is more than or equal to the internal diameter of steel pipe, and the socket enlarging of socket steel pipe 2 is engaged with the bellmouth enlarging of bellmouth steel pipe 1, seals
Circle 4 is engaged with the bellmouth enlarging inwall of bellmouth steel pipe 1, the bellmouth steel pipe between double indents 3 at the socket enlarging of socket steel pipe 2
Water filling port 5 is set on 1 bellmouth enlarging wall.
