Abstract
The invention discloses a pipe-end port structure for high-pressure delivery pipelines. The pipe-end port structure comprises an inner embedded pipe, an outer sleeve and two pipe-end structures. The two pipe-end structures are connected with each other by the inner embedded pipe, two ends of the inner embedded pipe are inserted into the two pipe-end structures, threads are arranged on the outside of each pipe-end structure, the outer sleeve is connected with the two pipe-end structures in a threaded manner, an annular stepped surface is arranged on the inner side of an end of each pipe-end structure, the radial width of each annular stepped surface is identical to the thickness of the inner embedded pipe, the inner embedded pipe is mounted inside the annular stepped surfaces in an embedded manner, and sealing pads are arranged among the inner embedded pipe and the annular stepped surfaces. The pipe-end port structure for the high-pressure delivery pipelines has the advantages that the two pipe-end structures are connected with each other by the outer sleeve, and the sealing pads are abutted to the pipe-end structures by the inner embedded pipe, so that the pipe-end structures can be hermetically connected with each other; owing to the sleeve, the inner embedded pipe can bear pressure; tension of the inner embedded pipe is constrained by the annular stepped surfaces, so that the inner embedded pipe can assuredly be in close fit with the pipe-end structures.
Description
Technical field
The present invention relates to a kind of high pressure delivery pipes pipe end interface structure, belong to high-pressure delivery petroleum pipeline technical field.
Background technique
Sealing problem after the petroleum pipeline butt joint is a very important problem, prior art is often used flange-interface to connect and is sealed, its structure is comparatively complicated, and the pulling force that bolt bears in the process of flange-interface sealing is bigger, the pulling force that bolt bears is delivered on the flange, also easily flange is brought damage, thus to the requirement of flange than higher.Simultaneously, owing to bear big stress effect for a long time, the bolt that flange and adpting flange are used will inevitably produce the fatigue stress phenomenon after using a period of time, so service time, more easy appearance more of a specified duration damaged.
Simultaneously, because petroleum pipeline is in high pressure, the process of carrying at a high speed, the sealing under the pipeline hyperbaric environment also is the technical problem that prior art faces, and adopts conventional flange to connect and can not satisfy the high pressure that increases day by day, the requirement of carrying at a high speed.
Summary of the invention
In order to solve the excessive technical problem of pipe end constructions seal structure complex, stress of petroleum pipeline, solve the problem of petroleum pipeline pressure-bearing simultaneously, the invention provides a kind of high pressure delivery pipes pipe end interface structure.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of high pressure delivery pipes pipe end interface structure, comprise embedded pipe, outer sleeve and two pipe end constructions, connect by embedded pipe between two described pipe end constructions, two described pipe end constructions inside are inserted at the two ends of described embedded 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, the inboard, end of each described pipe end constructions is provided with the annular table terrace, radial width at described annular table terrace is identical with the thickness of described embedded pipe, make described embedded pipe built be installed in annular table terrace inside, tell between the annular table terrace and be provided with sealing gasket at described embedded pipe and institute.
The middle part of described outer sleeve is provided with integrated hexagon nut structure.
A kind of high pressure delivery pipes pipe end interface structure of the present invention, by outer sleeve two pipe end constructions are connected, and between two pipe end constructions, be tightly connected by embedded pipe top tight sealing pad and then realization, because the existence of outer sleeve, embedded pipe itself can pressure-bearing, and limited by the tension force of ring-shaped step in the face of embedded pipe, can guarantee that embedded tube and tube end structure closely cooperates, and owing to sealing gasket itself does not contact with ambient air, so can prolong the working life of sealing gasket, delay the deterioration phenomenon of sealing gasket, and reduce the problem of the corrosion of sealing gasket.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a kind of structural drawing of high pressure delivery pipes pipe end interface structure.
Among the figure: 1, embedded pipe; 2, outer sleeve; 3, pipe end constructions; 4, hexagon nut structure.
Embodiment
As shown in Figure 1, the described a kind of high pressure delivery pipes pipe end interface structure of the embodiment of the invention, comprise embedded pipe, outer sleeve and two pipe end constructions, connect by embedded pipe between two described pipe end constructions, two described pipe end constructions inside are inserted at the two ends of described embedded 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, the inboard, end of each described pipe end constructions is provided with the annular table terrace, radial width at described annular table terrace is identical with the thickness of described embedded pipe, make described embedded pipe built be installed in annular table terrace inside, tell between the annular table terrace and be provided with sealing gasket at described embedded pipe and institute.
The middle part of described outer sleeve is provided with integrated hexagon nut structure.
A kind of high pressure delivery pipes pipe end interface structure of the present invention, by outer sleeve two pipe end constructions are connected, and between two pipe end constructions, be tightly connected by embedded pipe top tight sealing pad and then realization, because the existence of outer sleeve, embedded pipe itself can pressure-bearing, and limited by the tension force of ring-shaped step in the face of embedded pipe, can guarantee that embedded tube and tube end structure closely cooperates, and owing to sealing gasket itself does not contact with ambient air, so can prolong the working life of sealing gasket, delay the deterioration phenomenon of sealing gasket, and reduce the problem of the corrosion of sealing gasket.
