Abstract

The utility model discloses an embedded type high-pressure petroleum transportation pipeline which comprises a body. The body is in a circular tube shape, the two ends of the body are respectively provided with a thickened outer wall, an annular cutting groove is formed in the outer end face of each thickened outer wall, the inner wall of each annular cutting groove is smooth, the cross section of each annular cutting groove is of a rectangular structure, each annular cutting groove is located in the middle of the outer end face of each thickened outer wall, the thickened outer walls at the two ends of the body are respectively provided with external threads, and the thickness of each thickened outer wall is larger than the thickness of the middle wall of the body. According to the embedded type high-pressure petroleum transportation pipeline, seal rings can be conveniently installed due to the fact that the annular cutting grooves are formed, the annular cutting grooves can bear large pressure, the seal rings are prevented from expanding outward under the pressure-bearing environment, the oxidation rate of the seal rings inside the annular cutting grooves can be lowered, and the service life of the petroleum pipeline can be prolonged.

Description

A kind of embedded high-voltage transfer oil pipeline
Technical field
The utility model relates to a kind of embedded high-voltage transfer oil pipeline, belongs to high-pressure delivery petroleum pipeline technical field.
Background technique
Sealing problem after the petroleum pipeline docking is a very important problem, prior art often uses flange-interface connect and seal, its structure is comparatively complicated, and the pulling force that in the process of flange-interface sealing, bolt bears is larger, the pulling force that bolt bears is delivered on flange, also easily flange is brought damage, so higher to the requirement of flange.Simultaneously, owing to bearing for a long time large effect of stress, the bolt that flange and adpting flange are used will inevitably produce the fatigue stress phenomenon after using a period of time, so more of a specified duration more easily appearance of service time damages.
Simultaneously, in the process of high pressure, conveying at a high speed, the sealing under the pipe high-pressure environment is also the technical problem that prior art faces due to petroleum pipeline, adopts conventional flange to connect and can not satisfy the high pressure that day by day increases, the requirement that high speed is carried.
The model utility content
In order to solve the excessive technical problem of pipe end constructions seal structure complex, stress of petroleum pipeline, the utility model provides a kind of embedded high-voltage transfer oil pipeline.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of embedded high-voltage transfer oil pipeline, comprise body, body is cylindrical, the two ends of body have the thickening outer wall, are provided with the ring cutting groove, the inner wall smooth of described ring cutting groove on the exterior edge face of thickening outer wall, the transverse section of described ring cutting groove is rectangular configuration, described ring cutting groove is positioned at the middle part of exterior edge face of thickening outer wall, and is provided with outside thread on the thickening outer wall at the two ends of body, and the thickness of the thickening outer wall of body is greater than the wall thickness at body middle part.
The radial width of described ring cutting groove be described thickening outer wall thickness 1/3rd.
Described externally threaded length is less than the length of thickening outer wall.
A kind of embedded high-voltage transfer oil pipeline described in the utility model, the ring cutting groove is convenient to install seal ring, can bear larger pressure, and can prevent that seal ring from expanding outwardly under the pressure-bearing environment, and can reduce the oxidation rate of the seal ring of ring cutting inside grooves, extend the working life of petroleum pipeline.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is a kind of structural drawing of embedded high-voltage transfer oil pipeline.
Fig. 2 is use view of the present utility model.
In figure: 1, body; 2, thickening outer wall; 3, ring cutting groove.
Embodiment
As shown in Fig. 1-2, the described a kind of embedded high-voltage transfer oil pipeline of the utility model embodiment, comprise body 1, body 1 is cylindrical, the two ends of body 1 have thickening outer wall 2, be provided with ring cutting groove 3 on the exterior edge face of thickening outer wall 2, the inner wall smooth of described ring cutting groove, the transverse section of described ring cutting groove 3 is rectangular configuration, described ring cutting groove 3 is positioned at the middle part of the exterior edge face of thickening outer wall, and be provided with outside thread on the thickening outer wall at the two ends of body, the thickness of the thickening outer wall of body 1 is greater than the wall thickness at body middle part.
The radial width of described ring cutting groove 3 be described thickening outer wall thickness 1/3rd.
Described externally threaded length is less than the length of thickening outer wall.
A kind of embedded high-voltage transfer oil pipeline described in the utility model, the ring cutting groove is convenient to install seal ring, can bear larger pressure, and can prevent that seal ring from expanding outwardly under the pressure-bearing environment, and can reduce the oxidation rate of the seal ring of ring cutting inside grooves, extend the working life of petroleum pipeline.
