Abstract

The utility model discloses a high-pressure conveying pipeline which comprises a body in a circular tube shape. The two ends of the body are provided with thickened outer walls. Inner walls of the two ends of the body are respectively provided with an inward-concave circular tables. The radial width of each inward-concave circular table is equal to the thickness of the wall in the middle of the body. The thickened outer walls of the two ends of the body are provided with outer threads. The thickness of each thickened outer wall is more than two times more than the thickness of the wall in the middle of the body. The axial width of each inward-concave circular table is more than two times more than the thickness of each thickened outer wall. The axial width of each inward-concave circular table is smaller than the length of the threads of each thickened outer wall so as to ensure that each inward-concave circular table has enough space to contain a sealing gasket and a pipeline structure. According to the high-pressure conveying pipeline, the thickened outer walls are used for ensuring that the end portion of the pipeline has enough pressure-bearing capacity, the pipeline is connected with a corresponding pipeline through the inward-concave circular tables, so that sealing can be conducted conveniently, and bearing pressure is transferred to the corresponding pipeline, so that the sealing gasket does not need bearing pressure.

Description

A kind of high pressure delivery pipes
Technical field
The utility model relates to a kind of high pressure delivery pipes, 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, solve simultaneously the problem of petroleum pipeline pressure-bearing, the utility model provides a kind of high pressure delivery pipes.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of high pressure delivery pipes, comprise body, body is cylindrical, the two ends of body have the thickening outer wall, respectively have the indent round platform on the inwall at the two ends of body, the radial width of described indent round platform equals the wall thickness at body middle part, 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 more than the twice of wall thickness at body middle part.
The axial width of described indent round platform is more than the twice of thickness of thickening outer wall, and the axis width of described indent round platform is less than the externally threaded length of thickening outer wall, to guarantee that the indent round platform has enough spaces and holds sealing gasket and pipeline configuration.
Described externally threaded length is less than the length of thickening outer wall.
A kind of high pressure delivery pipes described in the utility model guarantees that by the thickening outer wall end of pipeline has enough bearing capacities; Be connected with corresponding pipeline by the indent round platform, be convenient to seal, and bearing capacity is imputed to corresponding pipeline, make sealing gasket itself not need pressure-bearing.
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 high pressure delivery pipes.
Fig. 2 is use view of the present utility model.
In figure: 1, body; 2, thickening outer wall; 3, indent round platform.
Embodiment
As shown in Fig. 1-2, the described a kind of high pressure delivery pipes of the utility model embodiment, comprise body 1, body 1 is cylindrical, the two ends of body 1 have thickening outer wall 2, respectively have indent round platform 3 on the inwall at the two ends of body 1, and the radial width of described indent round platform 3 equals the wall thickness at body middle part, and be provided with outside thread on the thickening outer wall 2 at the two ends of body 1, the thickness of the thickening outer wall 2 of body 1 is more than the twice of wall thickness at body middle part.
The axial width of described indent round platform is more than the twice of thickness of thickening outer wall, and the axis width of described indent round platform is less than the externally threaded length of thickening outer wall, to guarantee that the indent round platform has enough spaces and holds sealing gasket and pipeline configuration.
Described externally threaded length is less than the length of thickening outer wall.
A kind of high pressure delivery pipes described in the utility model guarantees that by the thickening outer wall end of pipeline has enough bearing capacities; Be connected with corresponding pipeline by the indent round platform, be convenient to seal, and bearing capacity is imputed to corresponding pipeline, make sealing gasket itself not need pressure-bearing.
