Abstract
The utility model is related to a kind of special joint of petroleum pipeline, including the first body and the second body that are attached by flange, leakage-proof structure is provided with the first body end and the second body end, the leakage-proof structure includes multistage cambered surface and the plane connected between adjacent two sections of cambered surfaces, the leakage-proof structure of the first body end cooperates with the leakage-proof structure of the second body end, between the leakage-proof structure of the first body end and the leakage-proof structure of the second body end, it is additionally provided with leak-proof washer, the leak-proof washer shape cooperates with the leakage-proof structure.The special joint of petroleum pipeline disclosed in the utility model, leakage-proof structure is used by pipeline end face, effectively prevent the problem of pipeline Oil spills, simultaneously, to leakage-proof structure inside by the way of cambered surface and plane be combined with each other, the leakage hidden danger that the connection of prior art midplane is caused can be made up, increasing leakage-proof ring on the inside of pipeline can also effectively reduce risk of leakage.
Description
Technical field
The utility model is related 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 used, two oil feed pipes are connected using common connector typically
It is connected together.The sealing of this connected mode is poor, and bonding strength is not high, using easily being threaded 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.
Utility model content
To solve above-mentioned technical problem present in prior art, the utility model is closed there is provided a kind of scientific structure design
The special joint of the petroleum pipeline of reason.The utility model is achieved through the following technical solutions:
A kind of special joint of petroleum pipeline, including the first body and the second body being attached by flange,
One body end is provided with leakage-proof structure with the second body end, and the leakage-proof structure includes multistage cambered surface and adjacent two
The plane connected between section cambered surface, the leakage-proof structure phase of the leakage-proof structure of the first body end and the second body end
Mutually coordinate, between the leakage-proof structure of the first body end and the leakage-proof structure of the second body end, be additionally provided with
Leak-proof washer, 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 opposite.
Further, on the tip inside surface that first body and the second body are connected with each other, 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 beneficial effects of the utility model are:
The special joint of petroleum pipeline disclosed in the utility model, uses leakage-proof structure, effectively by pipeline end face
The problem of pipeline Oil spills is avoided, meanwhile, to leakage-proof structure inside by the way of cambered surface and plane be combined with each other, can
The leakage hidden danger that the connection of prior art midplane is caused is made up, increasing leakage-proof ring on the inside of pipeline can also effectively reduce leakage wind
Danger.
Brief description of the drawings
Fig. 1 is the special joint structural representation of petroleum pipeline disclosed in the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings, to help understanding content of the present utility model, our department
The description for dividing only is exemplary and explanatory, should not have any restriction effect to protection domain of the present utility model.
As shown in figure 1, a kind of special joint of petroleum pipeline, including connected by flange 4 and unit bolt nut 3
The first body 1 and the second body 7 for connecing, leakage-proof structure is provided with the end of the first body 1 and the end of the second body 7, 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
The leakage-proof structure of leakage-proof structure and the end of the second body 7 cooperate, 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 is opposite with the bending direction of cambered surface 6.
Further, on the surface of the tip inside being connected with each other in 1 and second body of the first body 7, 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 preferred embodiment of the present utility model, this is not limited to
Utility model, although being described in detail to the utility model with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent.It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc.,
Should be included within protection domain of the present utility model.
