Abstract
The utility model discloses a pipe end port structure of a petroleum pipeline. The pipe end port structure comprises a seal pipe, an outer sleeve and two pipe end structures. The two pipe end structures are connected through the seal pipe. The two ends of the seal pipe are inserted into the inner portions of the two pipe end structures. The outer portion of each pipe end structure is provided with threads. The outer sleeve is connected with the two pipe end structures through the threads. The middle position of the seal pipe is provided with an annular protruding portion, and the two side faces of the annular protruding portion are respectively provided with a sealing gasket. According to the pipe end port structure of the petroleum pipeline, the two pipe end structures are connected through the outer sleeve, the two pipe end structures are in seal connection through the seal pipe, due to the existence of the outer sleeve, the sealing gaskets on the seal pipe can be isolated from the external environment, and therefore the service life of the sealing gaskets can be prolonged, the aging phenomenon of the sealing gaskets can be delayed, and corrosion of the sealing gaskets is reduced.
Description
Technical field
The utility model relates to a kind of petroleum pipeline pipe end interface structure, belongs to the 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.
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 petroleum pipeline pipe end interface structure.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of petroleum pipeline pipe end interface structure, comprise sealed pipe, outer sleeve and two pipe end constructions, between two described pipe end constructions, by sealed pipe, connect, two described pipe end constructions inside are inserted at the two ends of described sealed pipe, the outside of each pipe end constructions is provided with screw thread, described outer sleeve is connected with two pipe end constructions by screw thread, and the neutral position of described sealed pipe is provided with ring-shaped protrusion, and two sides of ring-shaped protrusion are respectively equipped with sealing gasket.
The surface of described sealed pipe is provided with the fin of arranging vertically, and is provided with guide groove in the inside of pipe end constructions, and described fin coordinates with described guide groove.
The middle part of described outer sleeve is provided with integrated hexagon nut structure.
A kind of petroleum pipeline pipe end interface structure described in the utility model, by outer sleeve, two pipe end constructions are connected, and by sealed pipe, be connected and sealed between two pipe end constructions, existence due to outer sleeve, sealing gasket on sealed pipe can be realized with external environment condition isolated, so can extend the working life of sealing gasket, delay the deterioration phenomenon of sealing gasket, and reduce the problem of the corrosion of sealing gasket.
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 petroleum pipeline pipe end interface structure.
In figure: 1, sealed pipe; 2, outer sleeve; 3, pipe end constructions; 4, hexagon nut structure.
Embodiment
As shown in Figure 1, the described a kind of petroleum pipeline pipe end interface structure of the utility model embodiment, comprise sealed pipe 1, outer sleeve 2 and two pipe end constructions 3, between two described pipe end constructions 3, by sealed pipe 1, connect, two described pipe end constructions 3 inside are inserted at the two ends of described sealed pipe 1, the outside of each pipe end constructions 3 is provided with screw thread, described outer sleeve 2 is connected with two pipe end constructions 3 by screw thread, the neutral position of described sealed pipe 1 is provided with ring-shaped protrusion, and two sides of ring-shaped protrusion are respectively equipped with sealing gasket.
The surface of described sealed pipe 1 is provided with the fin of arranging vertically, and is provided with guide groove in the inside of pipe end constructions 3, and described fin coordinates with described guide groove.
The middle part of described outer sleeve 2 is provided with integrated hexagon nut structure 4.
A kind of petroleum pipeline pipe end interface structure described in the utility model, by outer sleeve, two pipe end constructions are connected, and by sealed pipe, be connected and sealed between two pipe end constructions, existence due to outer sleeve, sealing gasket on sealed pipe can be realized with external environment condition isolated, so can extend the working life of sealing gasket, delay the deterioration phenomenon of sealing gasket, and reduce the problem of the corrosion of sealing gasket.
