Abstract
The utility model discloses a high pressure delivery pipeline pipe end connector structure. The high pressure delivery pipeline pipe end connector structure comprises an inner embedded pipe, an outer sleeve and two pipe end structures, wherein the two pipe end structures are connected through the inner embedded pipe, and the two ends of the inner embedded pipe are inserted into the two pipe end structures; a thread is arranged outside each pipe end structure, and the outer sleeve is connected with the two pipe end structures through the threads; an annular step surface is arranged on the inner side of the end portion of each pipe end structure, wherein the radial width of the annular step surface is equal to the thickness of the inner embedded pipe, the inner embedded pipe is made to be installed inside the annular step surface in an embedded mode, and a sealing gasket is arranged between the inner embedded pipe and the annular step surface. According to the high pressure delivery pipeline pipe end connector structure, the two pipe end structures are connected through the outer sleeve, and the inner embedded pipe tightly abuts against the sealing gaskets between the two pipe end structures so as to realize sealing connection; due to the existence of the outer sleeve, the inner embedded pipe can bear pressure; besides, the tension of the inner embedded pipe is restricted by the annular step surfaces, and therefore the effect that the inner embedded pipe is in tight fit with the pipe end structures can be ensured.
Description
Technical field
The utility model relates to a kind of high pressure delivery pipes pipe end interface structure, 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 after using a period of time, will inevitably produce the fatigue stress phenomenon, 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 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, solve simultaneously the problem of petroleum pipeline pressure-bearing, the utility model provides a kind of high pressure delivery pipes pipe end interface structure.
The purpose of this utility model is carried out 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, it is inner that two described pipe end constructions 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 arranged on the annular table terrace inner, 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 described in the utility model, by outer sleeve, two pipe end constructions are connected, and be tightly connected by embedded pipe top tight sealing pad and then realization between two pipe end constructions, existence due to outer sleeve, embedded pipe itself can pressure-bearing, and by the tension force of ring-shaped step in the face of embedded pipe, limited, can guarantee that embedded tube and tube end structure closely cooperates, and because sealing gasket itself does not contact with ambient air, 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.

Below according to drawings and embodiments the utility model is described in further detail.
Fig. 1 is a kind of structural drawing of high pressure delivery pipes pipe end interface structure.
In 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 utility model embodiment, comprise embedded pipe, outer sleeve and two pipe end constructions, connect by embedded pipe between two described pipe end constructions, it is inner that two described pipe end constructions 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 arranged on the annular table terrace inner, 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 described in the utility model, by outer sleeve, two pipe end constructions are connected, and be tightly connected by embedded pipe top tight sealing pad and then realization between two pipe end constructions, existence due to outer sleeve, embedded pipe itself can pressure-bearing, and by the tension force of ring-shaped step in the face of embedded pipe, limited, can guarantee that embedded tube and tube end structure closely cooperates, and because sealing gasket itself does not contact with ambient air, 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.
