This connector is used for connecting two petroleum transportation pipelines of mutually perpendicular, and its joint strength is high, is difficult to appear the oil spills.
Description
Technical field
The utility model relates to a kind of pipe coupling, especially a kind of petroleum transportation pipeline Special connecting joint.
Background technique
At present, in the connecting head that oil transportation adopts, two oil feed pipes link together by the common connecting head of general employing.The sealing of this Placement is poor, and join strength is not high, easily threads off, cause the leakage of oil, thus cause the waste of resource, the deficiency that Here it is existing for prior art after using a period of time.
Summary of the invention
The technical problems to be solved in the utility model, be exactly for the deficiency existing for prior art, and provide a kind of petroleum transportation pipeline Special connecting joint, this connecting head is for connecting orthogonal two petroleum transportation pipelines, its join strength is high, is not easy to occur Oil spills.
This programme is achieved by the following technical measures: this petroleum transportation pipeline Special connecting joint comprises the connecting head body in 90 ° of bendings, the two ends of described connecting head body are respectively arranged with adpting flange I, the end of petroleum transportation pipeline is provided with the adpting flange II coordinated with adpting flange I, male half coupling is provided with inside the two ends end face of described connecting head body, the recessed seam coordinated with male half coupling is provided with inside the end face of described petroleum transportation pipeline, the outside two ends end face of described connecting head body being positioned at male half coupling is along the circumferential direction evenly provided with multiple stepped connection bump, the end face of described petroleum transportation pipeline is provided with the shoulder hole coordinated with connection bump.
Above-mentioned connection bump comprises first protruding and the second projection, and the diameter of the first projection is greater than the diameter of the second projection, and its good seal performance of this structural type, is not easy to occur Oil spills.
Above-mentioned first projection is connected with the end face of connecting head body, and the second projection is connected with the first projection.
Above-mentioned first cross section that is protruding and the second projection is circular, is not easy to occur sealing dead angle.
Gasket seal is provided with, to strengthen sealability between the two between above-mentioned adpting flange I and adpting flange II.
Above-mentioned adpting flange I is fixedly connected with by bolt assembly with adpting flange II, while ensureing the needs be fixedly connected with, and also can be for convenience detach.
The beneficial effect of this programme can be learnt according to describing of such scheme, in this petroleum transportation pipeline Special connecting joint, the two ends of connecting head body are respectively arranged with adpting flange I, the end of petroleum transportation pipeline is provided with the adpting flange II coordinated with adpting flange I, by coordinating of adpting flange I and adpting flange II, realize being fixedly connected with of connecting head body and petroleum transportation pipeline, its join strength is high, there will not be the phenomenon of dropout.Male half coupling is provided with inside the two ends end face of described connecting head body, the recessed seam coordinated with male half coupling is provided with inside the end face of described petroleum transportation pipeline, male half coupling coordinates with recessed seam, realize the axially locating to connecting head body and petroleum transportation pipeline on the one hand, meanwhile, the sealability of both joints can also be strengthened.The outside two ends end face of described connecting head body being positioned at male half coupling is along the circumferential direction evenly provided with multiple stepped connection bump, the end face of described petroleum transportation pipeline is provided with the shoulder hole coordinated with connection bump, connection bump coordinates with shoulder hole, further increases the sealability between connecting head body and petroleum transportation pipeline.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1-petroleum transportation pipeline, 2-bolt assembly, 3-adpting flange II, 4-adpting flange I, 5-connecting head body, the recessed seam of 6-, 7-male half coupling, 8-second is protruding, and 9-first is protruding, 10-connection bump, 11-shoulder hole, 12-gasket seal.
Embodiment
For the technical characterstic of this programme can be clearly demonstrated, below by embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of petroleum transportation pipeline Special connecting joint, it comprises the connecting head body 5 in 90 ° of bendings, the two ends of described connecting head body 5 are respectively arranged with adpting flange I 4, the end of petroleum transportation pipeline 1 is provided with the adpting flange II 3 coordinated with adpting flange I 4, be provided with gasket seal 12 between adpting flange I 4 and adpting flange II 3, adpting flange I 4 is fixedly connected with by bolt assembly 2 with adpting flange II 3.By coordinating of adpting flange I 4 and adpting flange II 3, realize being fixedly connected with of connecting head body 5 and petroleum transportation pipeline 1, its join strength is high, there will not be the phenomenon of dropout.
Male half coupling 7 is provided with inside the two ends end face of described connecting head body 5, the recessed seam 6 coordinated with male half coupling 7 is provided with inside the end face of described petroleum transportation pipeline 1, coordinated with recessed seam 6 by male half coupling 7, realize the axially locating to connecting head body 5 and petroleum transportation pipeline 1 on the one hand, meanwhile, the sealability of both joints can also be strengthened.
The outside two ends end face of described connecting head body 5 being positioned at male half coupling 7 is along the circumferential direction evenly provided with multiple stepped connection bump 10, the end face of described petroleum transportation pipeline 1 is provided with the shoulder hole 11 coordinated with connection bump 10.Described connection bump 10 comprises the first protruding 9 and second projection 8, and the diameter of the first projection 9 is greater than the diameter of the second projection 8, first protruding 9 is connected with the end face of connecting head body 5, and second protruding 8 is connected with first protruding 9, and the cross section of the first protruding 9 and second projection 8 is circular.Stepped connection bump 10 coordinates with shoulder hole 11, further increases the sealability between connecting head body 5 and petroleum transportation pipeline 1.
Can existing techniques in realizing be passed through without the technical characteristics described in the utility model, not repeat them here.The utility model is not limited in above-mentioned embodiment, the change that those of ordinary skill in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
