Abstract
A fully closed expansion joint of a direct-buried corrugated pipe consists of a steel end tube, a working corrugated pipe, a protective corrugated pipe, an organic protective shell and a bearing shell component. The working corrugated pipe is arranged on a steel pipeline; one end is welded on a flange welded on the steel end pipe; another end is connected with the bearing shell component. The organic protective shell made of the same material as an insulating bushing is arranged outside the expansion joint; two ends of the protective shell are connected with the respective ends of two protective corrugated pipes; another end of the protective corrugated pipe has a connecting bushing; the steel end pipe is formed from a front steel pipe and a rear steel pipe; the flange is welded on the adjacent end surfaces of two steel pipes respectively and on the working corrugated pipe; a guide flow cylinder inserted into the rear steel pipe is welded in the front steel pipe. The corrugated expansion joint not only absorbs the displacement of the pipeline but also avoids the impact on the corrugated pipe from the external environment; thereby the connection of the insulating shell of the pipeline is more safe and reliable.
Description
Technical field
The utility model relates to the pipe transportation technology field, especially can prevent a kind of totally enclosed direct-burried bellows expansion joint of external environment condition to working portion influence in the expansion joint.
Background technique
At present; the direct-burried expansion joint has multiple pattern; expansion joint under the general environment condition is relatively simple for structure; and it is abominable for ambient conditions as under the many situations of hazardous medium in level of ground water height, the environment; the structure of direct-burried expansion joint is wanted the many of complexity; it generally is made up of institutes such as work bellows, protection bellows, end pipe, protection housing, bearing shells, and the protection bellows is used for preventing the influence of external environment condition to work ripple tubular portion, and the protection bellows generally adopts the reasonable material of corrosion resisting property.But also have the carbon-steel parts of part to be naked state in the expansion joint, directly contact with environment facies, though carbon-steel parts has anti-corrosion measure, it still can not well prevent the influence of external environment condition to it.Because the part that is connected with external polyethylene pipe insulation sleeve pipe on the expansion joint is a metal tube, the reliability of the two connection is relatively poor.
Summary of the invention
In order to overcome the deficiency that existing direct-burried expansion joint can not play completely aspects such as sealing and pipe insulation sleeve pipe connection reliability be relatively poor, the utility model provides a kind of hermetic direct-burried bellows expansion joint, displacement that not only can extraction duct, and can completely cut off the influence of external environment condition to bellows, it is safer reliable that the connection of pipe insulation shell becomes.
For achieving the above object, the utility model adopts following technological scheme;
Described totally enclosed direct-burried bellows expansion joint, by steel end pipe, work bellows, protection bellows, organic material protection housing and pressure cylinder assembly are formed; Its work bellows is installed on the steel pipeline, an end and the flange plate welding that is welded on the steel end pipe, and the other end is connected with the pressure cylinder assembly; In the expansion joint outside organic material protection housing that is made with the thermal insulation casing same material is arranged, protection housing two ends link to each other with two protection bellowss end separately respectively, and the other end of protection bellows has adapter sleeve.
Described totally enclosed direct-burried bellows expansion joint, its steel end pipe is made up of forward and backward two joint steel pipes, and two save difference welding flange on the adjacent end face of steel pipes, with the welding of work bellows; In the steel pipe of front, be welded with the guide shell that is inserted in the steel pipe of back.
Described totally enclosed direct-burried bellows expansion joint, its expansion joint also can be made up of a work bellows and a protection bellows.
Owing to adopted technological scheme as mentioned above, the utlity model has following good effect:
This totally enclosed direct-burried bellows expansion joint not only can extraction duct the stress that produces of displacement; simultaneously also make the metalwork on the expansion joint be completely enclosed within the protection frame set of making by the good organic material of environmental resistance, make it avoid the influence of external environment.

Embodiment
With reference to Fig. 1, this totally enclosed direct-burried bellows expansion joint, by steel end pipe (1), work bellows (7), protection bellows (4), organic material protection housing (3) and pressure cylinder (6) assembly are formed; Its work bellows is installed on the steel pipeline, an end and the flange plate welding that is welded on the steel end pipe, and the other end is connected with the pressure cylinder assembly; Adopted in the expansion joint outside and thermal insulation casing (9) the identical materials organic material protection housing (3) that is made, protection housing two ends link to each other with two protection bellowss end separately respectively, protect the other end of bellows to have adapter sleeve (2).
The steel end pipe (1) of this totally enclosed direct-burried bellows expansion joint is made up of forward and backward two joint steel pipes, and two save difference welding flange on the adjacent end face of steel pipes, with work bellows (7) welding; In the steel pipe of front, be welded with the guide shell (8) that is inserted in the steel pipe of back.
Owing to being connected at the protection housing (3) that adopt the outside and the organic material of pipe insulation sleeve pipe (9) same material is made of expansion joint and the adapter sleeve (2) of same material, make with two organic materials respectively at the two ends of protection housing, can axial tension or protection bellows (4) end separately of compression link to each other, adapter sleeve (2), organic material protection housing (3), protection bellows (4) connects together, and makes the working portion steel end pipe (1) of expansion joint, work bellows (7), pressure cylinder assembly (6), guide shell (8) is closed in the cavity that is surrounded by above-mentioned part; End pipe (1) connects together with pipeline (11), and adapter sleeve (2) connects together with pipe insulation sleeve pipe (9), and handles through job site thermal insulation layer (10), realizes the complete closed of expansion joint and pipeline like this.Make expansion joint not only can absorb displacement like this, make simultaneously the metalwork of expansion joint and the influence that pipeline is not subjected to external environment again.
Claims (2)
1, a kind of totally enclosed direct-burried bellows expansion joint, by steel end pipe (1), work bellows (7), protection bellows (4), organic material protection housing (3) and pressure cylinder (6) assembly are formed; Its work bellows is installed on the steel pipeline, an end and the flange plate welding that is welded on the steel end pipe, and the other end is connected with the pressure cylinder assembly; It is characterized in that: described bellows expansion joint, the organic material protection housing (3) that is made with the thermal insulation casing same material is arranged in the expansion joint outside, protection housing two ends link to each other with two protection bellowss end separately respectively, and the other end of protection bellows has adapter sleeve (2); Its steel end pipe (1) is made up of forward and backward two joint steel pipes, and two save difference welding flange on the adjacent end face of steel pipes, with work bellows (7) welding; In the steel pipe of front, be welded with the guide shell (8) that is inserted in the steel pipe of back.
