In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of welded tube socket joint linkage structure, comprise bellmouth, socket and seal ring, socket is inserted in bellmouth, establishes seal ring between socket and bellmouth; Described bellmouth end is provided with straight mouth section and integrated Seal cage, and socket end is provided with chamfering, internal diameter of the seal ring and socket external diameter compact siro spinning technology, and external diameter and bellmouth Seal cage contacting side have the shape adapted with Seal cage, have v-depression with liquid contacting side.
Described one-body molded Seal cage is the annular tongue adopting machinery expanding method to be formed in welded tube bellmouth, longitudinally have the isosceles trapezoid profile with arc transition, and dual-side tilt angle is 20 ° ~ 30 ° along welded tube.
Described seal ring material is EPDM ethylene propylene diene rubber.
Described socket end-beveling is 40 ~ 45 °.
Described straight mouth segment length is 60 ~ 80mm, and the one-sided gap of straight mouth section internal diameter and socket external diameter is 2 ~ 4mm.
Compared with prior art, the beneficial effects of the utility model are:
1) achieve the socket joint Placement of welded tube, for welded tube pipe installation, there is epoch-making meaning;
2) relative welding manner, the construction of socket joint linkage structure is more convenient, greatly can improve efficiency of construction, reduces construction cost;
3) good sealing effect, seal ring repair and replacement are convenient;
4) socket can realize small angle adjustment in bellmouth, has certain angle adaptability, is conducive to site operation.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Seeing Fig. 1, is structural representation of the present utility model, and a kind of welded tube socket joint linkage structure, comprises bellmouth 2, socket 1 and seal ring 3, and socket 1 is inserted in bellmouth 2, establishes seal ring 3 between socket 1 and bellmouth 2; Described bellmouth 2 end is provided with straight mouth section 21 and integrated Seal cage 22, socket 1 end is provided with chamfering 11, seal ring 3 internal diameter and socket 1 external diameter compact siro spinning technology, external diameter and bellmouth Seal cage 22 contacting side have the shape adapted with Seal cage 22, have v-depression 31 with liquid contacting side.
Described one-body molded Seal cage 22 is the annular tongues adopting machinery expanding method to be formed in welded tube bellmouth 2, longitudinally have the isosceles trapezoid profile with arc transition, and dual-side tilt angle is 20 ° ~ 30 ° along welded tube.
Described seal ring 3 material is EPDM ethylene propylene diene rubber.
Described socket end-beveling 11 is 40 ~ 45 °.
Described straight mouth section 21 length is 60 ~ 80mm, and the one-sided gap of straight mouth section 21 internal diameter and socket 1 external diameter is 2 ~ 4mm.
Following examples are implemented under premised on technical solutions of the utility model, give detailed mode of execution and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment 1]
Adopt a kind of welded tube socket joint of the utility model linkage structure to realize the docking of ￠ 820 × 8 welded tube, its socket 1 end external diameter is ￠ 820, and end-beveling 11 is 5 × 45 °.Bellmouth 2 end straight mouth section 21 internal diameter is 826mm, and length is 60mm; On Seal cage 22 trapezoidal profile, edge lengths is 100mm, high 40mm, and dual-side angle of inclination is 30 °.
Seal cage 22 adopts mechanical cold diameter enlarging method to make welded tube bellmouth 2 end form annular tongue, accurately can control shape and the size of Seal cage 22, ensure the tightness of seal ring 3 and its laminating, thus make linkage structure have the good sealing effect of guarantee.
Seal ring 3 is EPDM EPT rubber packing circle, and internal diameter is 820mm, and external diameter and bellmouth Seal cage 22 contacting side have the shape adapted with Seal cage 22, have v-depression 31 with liquid contacting side.
During installation, be outwards sleeved on by seal ring v-depression 31 on socket 1, apart from 40mm place, end, then socket 1 is inserted bellmouth 2 from straight mouth section 21 and also arrive the degree of depth of specifying, installation can complete.
During use, pipeline inside has the medium of pressure to enter the Seal cage 22 sections of bellmouth 2, and whippy seal ring 3V type groove 31 place is under pressure backward outer expansion, is pressed between Seal cage 22 and socket 1, reaches good sealing effect.
Because socket 1 and bellmouth 2 joint have certain interval, during on-the-spot pipeline installation, in small angle range, tiltedly paving can realize with the connection angle of bellmouth 2 by regulating socket 1, saves the pipe fittings such as part elbow.Integral construction compares welding, and site operation cost reduces greatly, and efficiency of construction improves greatly.Used by reality, the good No leakage point of pipeline sealing effect.
When a kind of welded tube socket joint of the utility model linkage structure is safeguarded, only need in pipe bellmouth 2 one end or change seal ring 3 after being extracted socket 1 one end, very convenient.
