Abstract

The invention discloses an embedded sealing port structure for high-pressure delivery pipelines. The embedded sealing port structure comprises a sleeve, a first pipe-end structure and a second pipe-end structure. External threads are arranged on both the outside of the first pipe-end structure and the outside of the second pipe-end structure, the turning direction of the external threads of the first pipe-end structure is opposite to that of the external threads of the second pipe-end structure, the first pipe-end structure is connected with the second pipe-end structure by the sleeve, annularly cut semicircular grooves are formed at an end of the first pipe-end structure, annular semicircular protrusions are arranged at an end of the second pipe-end structure and are connected with the semicircular grooves in an embedded manner, the radius of each semicircular protrusion is smaller than that of each semicircular groove, and rubber is arranged inside the semicircular groove by means of injection molding. The embedded sealing port structure for the high-pressure delivery pipelines has the advantages that the first pipe-end structure and the second pipe-end structure are connected with each other by the sleeve and are sealed by the aid of the embedded semicircular grooves, the semicircular protrusions and the injection molding rubber among the semicircular grooves and the semicircular protrusions, accordingly, an excellent sealing effect can be realized, and the pipelines can bear high pressure assuredly.

Description

A kind of high pressure delivery pipes insert seal interface structure
Technical field
The present invention relates to a kind of high pressure delivery pipes insert seal 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 insert seal interface structure.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of high pressure delivery pipes insert seal interface structure, comprise sleeve pipe, first pipe end constructions and second pipe end constructions, first pipe end constructions and the second pipe end constructions outside all have outside thread and externally threaded rotation direction opposite, connect by sleeve pipe between first pipe end constructions and second pipe end constructions, be provided with the semi-circular recesses of ring cutting in the end of first pipe end constructions, and be provided with the semi-cylindrical hill of ring-type in the end of second pipe end constructions, described semi-cylindrical hill is connected with described semi-circular recesses is embedded, the radius of described semi-cylindrical hill is injected with rubber less than the radius of described semi-circular recesses in described semi-circular recesses inside.
The internal surface of described semi-circular recesses is friction surface, so that its injection molded elastomer guarantees later on to combine closely between rubber and the semi-circular recesses, plays good seal action.
The middle part of described outer sleeve is provided with integrated hexagon nut structure.
A kind of high pressure delivery pipes insert seal interface structure of the present invention, first pipe end constructions is connected by sleeve pipe with second pipe end constructions, and seal by Embedded semi-circular recesses and semi-cylindrical hill and the injection molded elastomer between them, can reach good sealing effect, guarantee that pipeline bears high pressure, and owing to can make injection molded elastomer and isolate from outer air, can prevent effectively that injection molded elastomer is aging, prolong the working life of pipeline.
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 insert seal interface structure.
Among the figure: 1, sleeve pipe; 2, first pipe end constructions; 3, second pipe end constructions; 4, hexagon nut.
Embodiment
As shown in Figure 1, the described a kind of high pressure delivery pipes insert seal interface structure of the embodiment of the invention, comprise sleeve pipe 1, first pipe end constructions 2 and second pipe end constructions 3, first pipe end constructions 2 and second pipe end constructions, 3 outsides all have outside thread and externally threaded rotation direction opposite, when reversing sleeve pipe 1, can apply lashing force to first pipe end constructions 2 and second pipe end constructions 3 simultaneously like this, connect by sleeve pipe between first pipe end constructions 2 and second pipe end constructions 3, be provided with the semi-circular recesses of ring cutting in the end of first pipe end constructions 2, and be provided with the semi-cylindrical hill of ring-type in the end of second pipe end constructions 3, described semi-cylindrical hill is connected with described semi-circular recesses is embedded, the radius of described semi-cylindrical hill is injected with rubber less than the radius of described semi-circular recesses in described semi-circular recesses inside.
The internal surface of described semi-circular recesses is friction surface, so that its injection molded elastomer guarantees later on to combine closely between rubber and the semi-circular recesses, plays good seal action.
The middle part of described outer sleeve is provided with integrated hexagon nut structure 4.
A kind of high pressure delivery pipes insert seal interface structure of the present invention, first pipe end constructions is connected by sleeve pipe with second pipe end constructions, and seal by Embedded semi-circular recesses and semi-cylindrical hill and the injection molded elastomer between them, can reach good sealing effect, guarantee that pipeline bears high pressure, and owing to can make injection molded elastomer and isolate from outer air, can prevent effectively that injection molded elastomer is aging, prolong the working life of pipeline.
