Abstract
The utility model discloses a joint for steel pipes. A casing of the joint is a closed ring. An annular groove is reserved on the inner side of the casing. Guide plates are fixed on vertical plates on two sides of the casing. A sealing glue cylinder is provided with two symmetrical annular expansion cavities inside. A support ring is further disposed in the first annular expansion cavity. By using joint for steel pipes, the speed of connecting steel pipes is fast, sealing effect of the steel pipes is well, and traditional steel pipe welding and flange connection are omitted. As the guide plates are further fixed to the vertical plates on two sides of the casing, connection of the steel pipes is more convenient. The joint has the advantages of low cost, low labor and convenience in maintenance.
Description
Technical field
The utility model relates to a kind of connector, more particularly relates to a kind of steel pipe jointing, and the steel pipe when being suitable for ground and provided underground pipe network connects.
Background technique
At present, the steel pipe when ground such as oil field, chemical industry, coal gas and water supply and provided underground pipe network connects, and normally adopts welding or flange to connect; Cost is high, workload is big, connection speed is slow; Belong to hard connection simultaneously, poor seismic behavior has brought inconvenience for the laying construction of steel pipe.
Summary of the invention
The purpose of the utility model provides a kind of steel pipe jointing; But when laying pipe network, not only dock to the steel pipe direct convenience; And need not weld or the flange connection; Cost is low, workload is little, installation rate is fast, good airproof performance, long service life, easy to maintenance, because it is strong to belong to the anti-seismic performance that is flexible coupling.
The purpose of the utility model is achieved in that it includes shell, it is characterized in that shell is closed annular solid, and the inboard of shell is provided with circular groove, is fixed with guide plate on the riser of shell both sides; Cartridge places in the circular groove of shell, in the cartridge tube, is provided with the swollen chamber of rising of the twice annular of symmetry, in the swollen chamber of rising, first road, also is provided with bracing ring; Said guide plate is an arc, is the skew symmetry shape in the left and right sides of shell.
The beneficial effect of the utility model is: because shell is closed annular solid; Cartridge places in the circular groove of shell; And removed the trouble that welding is connected with flange from; Owing on the riser of shell both sides, also be fixed with guide plate, make the connection speed of steel pipe fast again, simultaneously the bracing ring in the swollen chamber of rising make the steel pipe jointing long service life, have good seal performance, characteristics easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Fig. 1 is that this reality is made novel concrete structure generalized section;
Fig. 2 is the left view of steel pipe jointing.
Embodiment
In Fig. 1,2, shell 4 usefulness stainless steels are processed closed round ring shape, are provided with circular groove in the inboard of shell 4.Establish two guide plates respectively in the both sides of shell 4; Wherein on the bottom riser 3 in shell 4 left sides; Weld the guide plate 12 that two branches have several angle; The arcs of 2 one-tenth couplings of guide plate 12 and steel pipe also weld one and are the gusset 11 of vertical configuration with guide plate 12 on the shell stile 3 below the guide plate 12.The guide plate that has gusset 9 10 of two arcs of same welding on the top riser 3 on shell 4 right sides, the guide plate of the shell left and right sides is the skew symmetry shape.Cartridge 6 places in the circular groove of shell 4, is provided with the swollen chamber 5 of rising of ring-type of twice symmetry on the barrel in cartridge 6, in the swollen chamber of rising, first road, inserts a bracing ring 13 with certain degree of hardness and toughness, is used for strengthening the sealability of cartridge 6.
When laying steel pipe 2, one group of slide plate 1 that stalloy is processed on the uniform plug-in card of the left end of steel pipe jointing is used for preventing that the port of steel pipe 2 from scratching the inner tube wall of cartridge 6.Mouth of pipe load with steel pipe 2 is placed on the guide plate 12 of lower end, a steel pipe jointing left side again, at this moment promotes the steel pipe jointing and makes it pack into the mouth of pipe of steel pipe 2.Another root steel pipe is lifted in the right output port of steel pipe jointing, abut on the guide plate 10, insert in the steel pipe jointing, reserve the seam 7 that rises, at last slide plate 1 is all extracted out along guide plate 10.When steel pipe 2 built on stilts connections; Also can be when steel pipe 2 connects; At one end weld three stiffening plates 8 in the pipe of steel pipe 2; The steel pipe that is welded with stiffening plate 82 is injected stiffening plate 8 in the connector earlier, and the mouth of pipe load with steel pipe 2 is placed on the guide plate 12 of lower end, a steel pipe jointing left side again, at this moment promotes connector and under the guiding of supporting plate 12, packs into steel pipe 2.Adopting uses the same method again inserts the other end of another root steel pipe at the steel pipe jointing in the connector, and at this moment stiffening plate 8 inserts in another root steel pipe synchronously, reserves the seam 7 that rises.Owing in the pipe of two steel pipe jointings, be inserted with stiffening plate 8, increased the resistance to flexure of steel pipe interface.
