Abstract

The utility model relates to a universal convenient joint for steel pipeline, wherein, a positioning sleeve 4 is sheathed with the ends of a pipe 12 and a pipe 13 which are in a joint connection, the two ends are orderly symmetrically sheathed with a sealing ring 6, a clamping ring 3, a lock ring 2, a left cover 1 and a ringt cover 5. The left cover 1 is connected with a right cover 5 by a screw thread; when the left cover 1 and the right cover 5 screw the screw thread tightly at an opposite direction, the sealing ring 6 is pressed to open so as to seal the end of the pipes. The utility model has the advantages of strong versatility and quick installing, has not a high standard to mounting technique and equipment requirement. When the utility model is installed, time and labour are saved, structure is simple, manufacture is easy, a traditional pipe joint can be replaced, and the utility model is suitable for various pipelines for use.

Description

Steel pipe is with the omnipotent joint that makes things convenient for

The utility model relates to a kind of pipe joint, particularly steel pipe with the omnipotent joint that makes things convenient for.

The connection of steel pipe, conventional method are with being threaded, and the shortcoming of this method is:

1, mounting technique equipment is had relatively high expectations.A pipeline is installed, special-purpose machining screw instrument and certain technology must be arranged, waste time and energy.And at China's wide geographic area, rural area especially, difficulty is bigger.

2, whenever connect a pipe, the workman will be in pipe two ends machining screw, and need manufacture at the scene, and is both time-consuming, takes the labour again, influences construction speed.

The utility model purpose provides a kind of steel pipe with the omnipotent joint that makes things convenient for.Install fast, less demanding to technology and equipment, time saving and energy saving, and it is simple in structure, manufacture easily.

The utility model realizes that by following technological scheme it comprises left side lid 1, right lid 5, locking ring 2, snap ring 3, setting sleeve 4; This setting sleeve 4 is enclosed within the outside, end of the pipe 12,13 of intending butt joint, with this butt tube location, two ends of setting sleeve 4 are set with the left side lid 1 of seal ring 6, snap ring 3, locking ring 2 and left end and the right side lid 5 of right-hand member successively symmetrically on butt tube 12,13, with connection set left side lid 1 is connected with right lid 5.After installing, with this connection set left side lid 1 and right lid 2 are compressed in opposite directions, by abutment sleeve 4 with pressure through locking ring 2, snap ring 3, the seal ring 6 of rubber system compressed make, with the butt joint end seal of the pipe 12,13 of butt joint at spreading radially.

In sum, lid connected about the utility model adopted, setting sleeve butt joint location, seal with snap ring, locking ring compression sealing circle, simple in structure, installing/dismounting is all convenient, when installing, needn't dock the screw thread at pipe end place by site preparation, save the time greatly and reduced technical requirements, in addition, each part in the structure of the present utility model, all can be prefabricated in advance, directly use when mounted to get final product, accelerated construction speed.Also can make the series product of standard by standard pipe size, then use more extensive.The utility model versatility is stronger, installs fast, and is less demanding to technology and equipment, time saving and energy saving during installation, and it is simple in structure, manufactures easily.Model utility can replace traditional union, threeway, elbow, in connect, various pipe fittings such as external, be applicable on the various pipelines and use.

Do concrete introduction with embodiment below.

Fig. 1 is a structural drawing of the present utility model,

Fig. 2 is an another kind of structural drawing of the present utility model,

Fig. 3 is the A-A sectional view among Fig. 1 and Fig. 2.

As shown in Figure 1, be with setting sleeve 4 in the outside, steel pipe 12,13 ends of intending butt joint, with two steel pipes, 12,13 centerings, its two port is equipped with the seal ring of being made by rubber 6, snap ring 3 with claiming, locking ring 2, the left side lid 1 of left end and the right side lid 5 of right-hand member have outside thread on the outer round surface of the projection of right lid 5, have internal thread on the bore area of left side lid 1, this cylindrical outside thread and this endoporus screw-internal thread fit, the two connects together and has formed connection set.This structure is suitable for less caliber.As Fig. 2 is the structure that big caliber steel pipe is suitable for, about cover and have flange 8 on 1,5, this flange 8 is sleeved on the left and right lid 1,5, also can be made of one with it, with bolt 9, spring washer 10 and nut 7 with about cover 1,5 and be connected, constitute this connection set.As Fig. 1,2, about lid 1 and 5 all have conical bore, conical bore cooperates with the conical surface of locking ring 2, as Fig. 3, on locking ring 2, has opening 11, when during from the two ends axial compression, the locking ring 2 of circular cone contact more closely being wedged between steel pipe 12,13 and the left and right sides end cap 1,5 by connection set.Snap ring 3 is unnotched annulus, can remedy the deficiency of these locking ring 2 breach, prevents that the interior fluid of pipeline from when seal ring is extruded, leaking from locking ring 2 indentation, there.
