Abstract

The utility model discloses an embedded sealing connector structure of a high-pressure conveying pipeline. The embedded sealing connector structure of the high-pressure conveying pipeline comprises a sleeve, a first pipe end structure and a second pipe end structure. The outer portion of the first pipe end structure and the outer portion of the second pipe end structure are respectively provided with outer threads and the screwing direction of the outer threads of the first pipe end structure and the screwing direction of the outer threads of the second pipe end structure are reverse. The first pipe end structure and the second pipe end structure are connected through the sleeve. A semicircular groove which is cut in an annular mode is formed in one end portion of the first pipe end structure. An annular semicircular protrusion is arranged on one end portion of the second pipe end structure. The semicircular protrusion and the semicircular groove are connected in an embedded mode. The radius of the semicircular protrusion is smaller than that of the semicircular groove. Rubber is filled into the semicircular groove in an injection molding mode. According to the embedded sealing connector structure of the high-pressure conveying pipeline, the first pipe end structure and the second pipe end structure are connected through the sleeve and sealed through the embedded semicircular groove and the semicircular protrusion and the injection molding rubber between the semicircular groove and the semicircular protrusion so that the good sealing effect can be achieved and the pipeline can bear high pressure.

Description

A kind of high pressure delivery pipes insert seal interface structure
Technical field
The utility model relates to a kind of high pressure delivery pipes insert seal 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 insert seal 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 insert seal interface structure, comprise sleeve pipe, the first pipe end constructions and the second pipe end constructions, the 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 the first pipe end constructions and the second pipe end constructions, be provided with the semi-circular recesses of ring cutting in the end of the first pipe end constructions, and be provided with the semi-cylindrical hill of ring-type in the end of the 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 less than the radius of described semi-circular recesses, be injected with rubber in described semi-circular recesses inside.
The internal surface of described semi-circular recesses is friction surface,, so that its injection molded elastomer guarantees to combine closely between rubber and semi-circular recesses later, 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 described in the utility model, the first pipe end constructions be connected pipe end constructions and connect by sleeve pipe, and by Embedded semi-circular recesses and semi-cylindrical hill and the injection molded elastomer between them, seal, can reach good sealing effect, guarantee that pipeline bears high pressure, and, owing to can making injection molded elastomer and isolate from outer air, can prevent effectively that injection molded elastomer is aging, extend the working life of pipeline.
Description of drawings
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 insert seal interface structure.
In figure: 1, sleeve pipe; 2, the first pipe end constructions; 3, the 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 utility model embodiment, comprise sleeve pipe 1, the first pipe end constructions 2 and the second pipe end constructions 3, the first pipe end constructions 2 and the second pipe end constructions 3 outsides all have outside thread and externally threaded rotation direction opposite, can apply lashing force to the first pipe end constructions 2 and the second pipe end constructions 3 simultaneously like this when reversing sleeve pipe 1, connect by sleeve pipe between the first pipe end constructions 2 and the second pipe end constructions 3, be provided with the semi-circular recesses of ring cutting in the end of the first pipe end constructions 2, and be provided with the semi-cylindrical hill of ring-type in the end of the 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 less than the radius of described semi-circular recesses, be injected with rubber in described semi-circular recesses inside.
The internal surface of described semi-circular recesses is friction surface,, so that its injection molded elastomer guarantees to combine closely between rubber and semi-circular recesses later, 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 described in the utility model, the first pipe end constructions be connected pipe end constructions and connect by sleeve pipe, and by Embedded semi-circular recesses and semi-cylindrical hill and the injection molded elastomer between them, seal, can reach good sealing effect, guarantee that pipeline bears high pressure, and, owing to can making injection molded elastomer and isolate from outer air, can prevent effectively that injection molded elastomer is aging, extend the working life of pipeline.
