Abstract
The utility model discloses a pipe connecting joint. The inner port of each of two ends of a steel ring is in an inclined horn shape, and an annular seam allowance is welded in the middle in the steel ring; a sealing ring is arranged in the inner port of each of the two ends of the steel ring; glands are annular, the inner ring of each gland is provided with an annular boss bent inwards, the two glands are respectively arranged on two sides of the steel ring, and the annular bosses of the glands are propped against the sealing rings; each gland is provided with screw holes distributed symmetrically and uniformly, and bolts are arranged in the screw holes; and the lower end of each locking lug is provided with a clamping groove, the locking lugs are uniformly fixed on the outer sides of the glands, and a positioning block is arranged in the clamping groove of each locking lug. The pipe connecting joint eliminates welding or flange connection in pipe connection, has a good sealing effect, and has the characteristics of low cost, low workload, high connecting speed and convenience in maintenance.
Description
Technical field
The utility model relates to a kind of connector, more particularly relates to a kind of tubing coupling, and the pipeline when being suitable for ground and provided underground steel pipe connects.
Background technique
At present; 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, and cost is high, workload is big, connection speed is slow, belongs to hard connection; 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 tubing coupling; But when laying pipe network, not only connect to the steel pipe direct convenience; Removed the trouble that welding is connected with flange from; Cost is low, workload is little, installation rate is fast, and it is good to belong to the anti-seismic performance that is flexible coupling, and good airproof performance, long service life, easy to maintenance.
The purpose of the utility model is achieved in that tubing coupling, and it includes steel ring, and mouth is and has the horn-like of gradient in the steel ring two ends, the seam of the annular of middle part welding in the steel ring circle; Seal ring place respectively the steel ring two ends in mouthful in, the cross section of seal ring is a wedge shape; Gland is an annular, and the interior ring of gland has the annular boss that bends towards the inboard, and two glands place its annular boss of both sides and the seal ring apical grafting of steel ring respectively; The screw that distributes is symmetrically and evenly arranged on the gland, and bolt places in the screw; The lower end of lock ear is provided with draw-in groove, and the lock ear evenly is fixed on the then outer of gland, and positioning block places in the draw-in groove of lock ear; Described steel ring its both sides be provided with gland on the corresponding riser of screw.
The utility model has the advantages that; Owing to adopted such scheme; Pipeline is connected removed welding to be connected with flange and since the steel ring two ends in mouthful be and have the horn-like of gradient, seal ring place respectively the steel ring two ends in the mouth; Make the good sealing effect of tubing coupling, have the advantages that cost is low, workload is little, installation rate is fast, 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 another embodiment.
Embodiment
In Fig. 1, mouth is and has the horn-like of gradient in steel ring 3 two ends, the seam 10 of the annular of middle part welding in steel ring 3 circles.Seal ring 4 usefulness rubber are processed, and its cross section is a wedge shape.Two seal rings 4 place respectively steel ring 3 two ends wedge-likes in mouthful in.Gland 5 is an annular, and ring has the annular boss 1 that bends towards the inboard in the gland 5, and gland 5 places the both sides of steel ring 3, on two glands 5, is distributed with the screw of symmetry, and bolt 2 places in the screw on the gland 5, makes annular boss 1 and seal ring 4 apical graftings on the gland 5.Lock ear 6 is three, four, five or six, and the lower end of lock ear 6 is provided with draw-in groove, and lock ear 6 evenly is welded on the then outer of gland 5, and positioning block 7 places in the draw-in groove on the lock ear 6.
In Fig. 2, the both sides of steel ring 3 also be provided with gland 5 on the corresponding riser 9 of bolt hole, on riser 9, have bolt hole, bolt 2 places in the screw on gland 5 and the corresponding riser 9, is used for bearing the connection of large diameter steel pipe.
When laying steel pipe 8, the steel ring 3 of tubing coupling is enclosed within 1 one ends of steel pipe 8 through seal ring 4.With the other end of another root steel pipe 8, after 8 of two steel pipes leave the seam that rises, the bolt on the gland is tightened again through the seal ring 4 reeve tubing couplings of offside.Make two annular boss 1 on the gland 5, compress in the having in gradient trumpet-shaped mouthful of wedge-shaped rubber seal ring 4 jacking steel rings 3 two ends respectively from the steel ring both sides.The positioning block 7 that to lock again in the ear 6 lower end draw-in grooves is weldingly fixed on the steel pipe 8, and it is antirust to coat modified pitch at last.
Should be understood that the utility model is not only limited to the structure of the foregoing description, in the scope of the purport that does not change the utility model, concerning those skilled in the art of common knowledge with related domain, also can carry out various changes and distortion.Therefore, such change and distortion should be interpreted as scope of the present invention and be included in the scope of the utility model.
Claims (2)
1. tubing coupling, it includes steel ring, it is characterized in that the steel ring two ends in mouth be and have the horn-like of gradient, the seam of the annular of middle part welding in the steel ring circle; Seal ring place respectively the steel ring two ends in mouthful in, the cross section of seal ring is a wedge shape; Gland is an annular, and the interior ring of gland has the annular boss that bends towards the inboard, and two glands place its annular boss of both sides and the seal ring apical grafting of steel ring respectively; The screw that distributes is symmetrically and evenly arranged on the gland, and bolt places in the screw; The lower end of lock ear is provided with draw-in groove, and the lock ear evenly is fixed on the then outer of gland, and positioning block places in the draw-in groove of lock ear; Described steel ring its both sides be provided with gland on the corresponding riser of screw.
2. tubing coupling according to claim 1 is characterized in that described lock ear is three, four, five or six.
