Abstract
The invention relates to a special joint for an oil pipeline. The special joint comprises a first pipe body and a second pipe body which are connected by flanges. Anti-leakage structures are arranged at both the end of the first pipe body and the end of the second pipe body. The anti-leakage structure comprises multiple cambered surfaces, and the flat surfaces arranged between two adjacent cambered surfaces. The anti-leakage structure at the end of the first pipe body and the anti-leakage structure at the end of the second pipe body coordinate with each other. Anti-leakage gaskets are arranged between the anti-leakage structure at the end of the first pipe body and the anti-leakage structure at the end of the second pipe body. The shape of the anti-leakage gaskets coordinates with the anti-leakage structures. According to the special joint for the oil pipeline, through the use of the anti-leakage structures at the pipeline end surfaces, the oil leakage problem of the oil pipeline is avoided effectively, at the same time, the combination of the cambered surfaces and the flat surfaces in the anti-leakage structure can compensate the potential leakage hazards which is prevalent in the prior art of planar connection. The adding of the anti-leakage ring can effectively reduce the leakage risk.
Description
Technical field
The present invention relates to petroleum transportation equipment technical field, refers in particular to a kind of special joint of petroleum pipeline.
Background technology
At present, in the connector that oil transportation is adopted, typically two oil feed pipes are connected using common connector
It is connected together.The sealing of this connected mode is poor, and bonding strength is not high, using easily threading off after a period of time, causes stone
The leakage of oil, so as to cause the waste of resource, here it is the weak point existing for prior art.
The content of the invention
To solve above-mentioned technical problem present in prior art, the invention provides a kind of scientific structure design is rational
The special joint of petroleum pipeline.The present invention is achieved through the following technical solutions：
A kind of special joint of petroleum pipeline, including the first body and the second body that are attached by flange, in first pipe
Body end portion is provided with leakage-proof structure with the second tube end portion, and the leakage-proof structure includes multistage cambered surface and in adjacent two sections of arcs
The plane connected between face, the leakage-proof structure phase interworking in the leakage-proof structure in the first tube end portion and the second tube end portion
Close, between the leakage-proof structure in the first tube end portion and the leakage-proof structure in the second tube end portion, be additionally provided with leakproof
Pad, the leak-proof washer shape cooperates with the leakage-proof structure.
Further, the cambered surface cross section is semicircle or minor arc.
Further, the leakage-proof structure adjacent both ends cambered surface bending direction is contrary.
Further, on the tip inside surface that first body and second pipe body phase connect, it is respectively arranged with
Leakage-proof ring, the leakage-proof ring end is provided with sawtooth, and the leakage-proof ring end sawtooth of first body is anti-with second body
Leakage circle end sawtooth intermeshing.
The invention has the beneficial effects as follows：
The special joint of petroleum pipeline disclosed in this invention, by adopting leakage-proof structure in pipeline end face, effectively prevent pipe
The problem of road Oil spills, meanwhile, to leakage-proof structure inside by the way of cambered surface and plane be combined with each other, can make up existing
The leakage hidden danger that the connection of technology midplane is caused, increasing leakage-proof ring on the inside of pipeline can also effectively reduce risk of leakage.
Description of the drawings
Fig. 1 is the special joint structural representation of petroleum pipeline disclosed by the invention.
Specific embodiment
Describe the present invention below in conjunction with the accompanying drawings, to help understanding present disclosure, the description of this part

The first body 1 for connecing and the second body 7, in the end of the first body 1 and the end of the second body 7 leakage-proof structure is provided with, described
Leakage-proof structure includes multistage cambered surface 2,6 and the plane 5 connected between adjacent two sections of cambered surfaces 2,6, the end of the first body 1
Leakage-proof structure cooperate with the leakage-proof structure of the end of the second body 7, in the leakage-proof structure of the end of the first body 1
And the leakage-proof structure of the end of the second body 7 between, be additionally provided with leak-proof washer 11, the shape of the leak-proof washer 11 with it is described
Leakage-proof structure cooperates.
Further, the cambered surface 2,6 cross sections are semicircle or minor arc.
Further, the leakage-proof structure adjacent both ends cambered surface 2 and the bending direction of cambered surface 6 are contrary.
Further, on the surface of the tip inside being connected with each other in the body 7 of first body 1 and second, set respectively
Be equipped with leakage-proof ring 10 and leakage-proof ring 8, the leakage-proof ring 10 and the end of leakage-proof ring 8 are provided with sawtooth 9, first body 1 it is anti-
Leakage 10 end sawtooth 9 of circle are intermeshed with the end sawtooth 9 of 7 leakage-proof ring of the second body 8.
Finally it should be noted that the foregoing is only the preferred embodiments of the present invention, the present invention is not limited to,
Although being described in detail to the present invention with reference to the foregoing embodiments, for a person skilled in the art, it still may be used
To modify to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic.
All any modification, equivalent substitution and improvements within the spirit and principles in the present invention, made etc., should be included in the present invention's
Within protection domain.
