Line, which is tightened, compresses sealing ring, complicated for operation and more time-consuming and laborious and higher cost.
Utility model content
The utility model aim is to provide for that a kind of structure is simple, good airproof performance, more economical one kind are for pipeline connection
Sealing structure.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
The utility model provides a kind of sealing structure for pipeline connection, and pipeline includes first pipe and the second pipe
Road, the first pipe end, which is bent outwardly, is formed with the first flange, and the second pipe end, which is bent outwardly, is formed with second
Flange, it is characterised in that: sealing structure includes clip, retaining ring, first flange and second flange, first flange
It is connected together with second flange by the clip, the retaining ring is located at the first pipe and the second pipe connects
It connects on the inner wall at place.
Further, the length direction of the curved direction of the first flange and the first pipe is in 100 ~ 130 degree of folders
The length direction of angle, the curved direction of the second flange and the second pipe is also in 100 ~ 130 degree of angles.
Further, cavity, the cavity are formed between first flange and second flange and the retaining ring
It is interior to be equipped with cylindrical annular packing.
Further, the cross section of the clip is V-shaped.
Further, the clip dimidiation is spelled after the first pipe and the second pipe are connected together
It connects to form a circular ring shape.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
First flange and the second flange of the utility model pass through clamp connection together, and first pipe and second pipe
The inner wall of junction is equipped with retaining ring, is tightly connected in this way, avoids a large amount of welding and other manufacturing flange, while the company of saving
Bolt, the nut connect, simplifies processing flow, has saved plenty of time cost and Material Cost.
Detailed description of the invention

Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
A kind of sealing structure for pipeline connection as depicted in figs. 1 and 2, wherein pipeline includes first pipe 1 and the
Two pipelines 2, sealing structure includes clip 5 and retaining ring 3, and 1 end of first pipe has been outwardly formed the first flange 6, second pipe 2
End has been outwardly formed the second flange 7, the first flange 6 and the second flange 7 and has been connected together by clip 5, and retaining ring 3 is located at first
On the inner wall of 2 junction of pipeline 1 and second pipe, for preventing gas, liquid or band in first pipe 1 and second pipe 2
The leakage of the fluid of solid particle guarantees the concentric of first pipe 1 and second pipe 2, and provides first pipe 1 and second pipe
Mistake proofing capability after 2 connections.
Optimally, it is formed with cavity between the first flange 6 and the second flange 7 and retaining ring 3, is equipped with cylindrical annular disk in cavity
Root 4.First flange 6 and the second flange 7 squeeze cylindrical annular packing 4 so that cylindrical annular packing 4 be fitted in the first flange 6,
On second flange 7 and retaining ring 3.In this way, between cylindrical annular packing 4 and the first flange 6, the second flange 7 and retaining ring 3, there are small
Gap, first pipe 1 and gas, liquid or the fluid with solid particle in second pipe 2 repeatedly shut off in gap,
To have the function that sealing, 4 dual-seal of retaining ring 3 and cylindrical annular packing, so that the sealing effect of the utility model is more preferable.
The length direction of the curved direction of first flange 6 and first pipe 1 is in 100 ~ 130 degree of angles, the bending of the second flange 7
Direction and the length direction of second pipe 2 be also in 100 ~ 130 degree of angles, shape is at a certain angle so that the first flange 6 and the
Two flange 7 are mutually closer to clamping convenient for clip 5 to the first flange 6 and the second flange 7.
For the clamping of production easy to process and clip 5 on the first flange 6 and the second flange 7, clip 5 is made as cross section
V-shaped two halves, the clip 5 of two halves by screw bolt and nut splice shape after first pipe 1 and second pipe 2 are connected together
At a circular ring shape.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, for example, clip 5, which can also be designed as other, to be turned over first
