Abstract

The utility model discloses an embedded type high-pressure petroleum conveying pipeline. The embedded type high-pressure petroleum conveying pipeline comprises a body, wherein the body is shaped like a round pipe, the two ends of the body are provided with thickened outer walls, a triangular annular concave groove is formed in the outer end surface of each thickened outer wall, the section of each triangular annular concave groove is a triangle, rubber is injected into the triangular annular concave grooves, each triangular annular concave groove is located in the middle of the outer end surface of each thickened outer wall, and outer threads are arranged on the thickened outer walls at the two ends of the body. According to the embedded type high-pressure petroleum conveying pipeline, the triangular annular concave grooves and the inside rubber can play a role in connection and sealing, can bear high pressure, and can prevent sealing rings from expanding outwards in a pressure bearing environment. Besides, due to the fact that after the rubber inside the triangular annular concave grooves is used for sealing connection, the contact area of the rubber and air is largely reduced, the oxidation speed of the rubber inside the triangular annular concave grooves can be lowered, and the service life of the petroleum pipeline is 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 to 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, after using a period of time, will inevitably produce the fatigue stress phenomenon, so more easily occur more for a long time service time damaging.
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 meet 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 carried out 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, on the exterior edge face of thickening outer wall, be provided with the triangle annular recess, the cross section of described triangle annular recess is triangle, in described triangle annular recess, is injected with rubber, described triangle annular recess 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.
Described triangle annular recess cross section be isosceles triangle, and the drift angle of isosceles triangle is obtuse angle.
The inwall of described triangle annular recess is rough surface, so that the rubber that is injection molding and triangle annular recess are combined closely.
A kind of embedded high-voltage transfer oil pipeline described in the utility model, triangle annular recess and inner rubber thereof, can play the effect that connects and seal, can bear larger pressure, and can prevent that seal ring from expanding outwardly under the pressure-bearing environment, and due to the rubber of triangle annular recess inside after being tightly connected, the area of contact of rubber and air will greatly reduce, so can reduce the oxidation rate of the rubber of triangle annular recess inside, extend the working life of petroleum pipeline.
The accompanying drawing explanation
Below according to drawings and embodiments the utility model is described in further detail.
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, triangle annular recess.
Embodiment
As shown in Figure 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, on the exterior edge face of thickening outer wall 2, be provided with triangle annular recess 3, the cross section of described triangle annular recess 3 is triangle, in described triangle annular recess 3, be injected with rubber 4, described triangle annular recess 3 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.
Described triangle annular recess cross section be isosceles triangle, and the drift angle of isosceles triangle is obtuse angle.
Adopt leg-of-mutton triangle annular recess, can make rubber when with the structure of triangular-section, contacting, stress distribution is more even, and can save the material of rubber, guarantees that body has enough intensity.
The inwall of described triangle annular recess is rough surface, so that the rubber that is injection molding and triangle annular recess are combined closely.
A kind of embedded high-voltage transfer oil pipeline described in the utility model, triangle annular recess and inner rubber thereof, can play the effect that connects and seal, can bear larger pressure, and can prevent that seal ring from expanding outwardly under the pressure-bearing environment, and due to the rubber of triangle annular recess inside after being tightly connected, the area of contact of rubber and air will greatly reduce, so can reduce the oxidation rate of the rubber of triangle annular recess inside, extend the working life of petroleum pipeline.
