Description
Technical Field
The utility model relates to the field of connecting pieces, in particular to a sealing joint for an oil pipeline.
Background
The oil pipeline is a main facility for unloading and transferring oil, generally, one oil pipeline is formed by connecting a plurality of single pipes with the same specification, and the requirement on the connecting part between the adjacent single pipes is high because the oil pipeline needs to bear higher conveying pressure in the oil transportation process. The mode that directly uses flange joint usually carries out the pipe connection between the monomer pipeline commonly used at present, and this kind of connected mode need use a plurality of bolts to install simultaneously when flange joint on the one hand, and the installation action is more loaded down with trivial details, and on the other hand is higher to the installation requirement, and each position atress of flange face just can guarantee long-term use in-process can not the oil leak when needing the installation.
Disclosure of Invention
The utility model mainly solves the technical problem of providing the oil pipeline sealing joint which can improve the efficiency and the sealing effect of pipeline connection.
In order to solve the technical problems, the utility model adopts a technical scheme that: there is provided an oil pipeline sealing joint, comprising: joint pipe and symmetry are installed the connector at joint pipe both ends, set up the hole that link up in the middle of joint pipe and two connectors, the joint pipe both ends set up the flange, the connector with joint pipe hookup location set up with flange assorted positioning groove, the length of connector surpasss the joint pipe, the connector surpasss and sets up the internal thread on the hole pore wall that the part corresponds, the external screw thread phase-match of internal thread and pipe joint position, the intermediate position of joint pipe sets up the interior boss, interior boss both sides are provided with first sealing washer installation position.
In a preferred embodiment of the present invention, the connector is a hexagon nut.
In a preferred embodiment of the utility model, the outer sides of the flanges at the two ends of the joint pipe are provided with second sealing ring mounting positions.
In a preferred embodiment of the utility model, ball structures are arranged at the contact positions of the flanges at the two ends of the joint pipe and the groove walls of the positioning groove.
In a preferred embodiment of the present invention, the first seal ring installation portion is embedded in a pipe wall of the joint pipe.
The utility model has the beneficial effects that: the utility model is a matching mechanism of an oil pipeline, a sealing ring is directly arranged on an inner boss in a joint pipe after the pipe port is positioned by the joint pipe, and then the pipe orifice and the boss are driven to be sealed through the action of the joint and the corresponding external thread of the pipe orifice.
Drawings
FIG. 1 is a schematic perspective view of a preferred embodiment of the present invention;
the parts in the drawings are numbered as follows:
1. the connector comprises a connector pipe, 2 connectors, 3 inner bosses, 4 flanges, 5 second sealing rings, 6 ball structures and 7 first sealing rings.
Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.
Referring to fig. 1, an embodiment of the present invention includes:
an oil pipeline sealing joint, comprising: a joint pipe 1 and connectors 2 symmetrically arranged at two ends of the joint pipe, a through inner hole is arranged between the joint pipe 1 and the two connectors 2, flanges 4 are arranged at two ends of the joint pipe 1, the joint 2 is a hexagonal nut convenient to fasten, a positioning clamping groove matched with the flange 4 is arranged at the connecting position of the hexagonal nut and the joint pipe 1, the length of the hexagonal nut exceeds the inner hole wall corresponding to the joint pipe 1 and is provided with an inner thread matched with an outer thread on an external pipe joint, an inner boss 3 is arranged in the middle of the joint pipe 1, first sealing ring mounting positions are arranged on two sides of the inner boss 3, the first sealing ring mounting position is partially embedded into the pipe wall of the joint pipe 1, and the first sealing ring 7 mounted at the first sealing ring mounting position is partially embedded into the pipe wall of the joint pipe, so that the first sealing ring 7 can be effectively prevented from shifting in the use process.
The flange 4 outsides at 1 both ends of adapter tube set up second sealing washer installation position, the installation of second sealing washer here can extrude with external pipeline joint's corresponding step position when carrying out the pipe connection, forms secondary seal point, further prevents the pipeline leakage. The ball structure 6 is arranged at the contact position of the flanges 2 at the two ends of the joint pipe 1 and the groove wall of the positioning groove, so that the resistance when the hexagonal nut is rotated during pipeline connection can be reduced.
The working principle of the embodiment is as follows:
the end part of a pipeline on one side is aligned with the middle through hole of the joint pipe 1, then the oil pipeline sealing joint is integrally moved until the internal thread of the hexagon nut is connected with the external thread area of the end of the pipeline, then the hexagon nut connector is rotated to enable the foremost end of the pipeline to reach the surface of one side of the inner boss 3 and to be in contact with the first sealing ring 7, at the moment, the end surface part of the boss structure of the external thread area of the pipeline is in contact with the second sealing ring 5 arranged on the outer side of the flange 4, at the moment, the hexagon nut is continuously rotated, and the oil pipeline sealing joint and the external pipeline are tightly connected and simultaneously realize double sealing of the connection area by compressing the two sealing rings. And then repeating the steps to connect the pipeline on the other side with the other side of the oil pipeline sealing joint, thus realizing the sealing connection of the two pipelines. When using this kind of sealing joint connecting tube, on the one hand, sealing washer mounted position has limit structure, can not shift easily, and seal structure is double-seal moreover, and is reliable and stable, and on the other hand, the hexagon nut structure of connector 2 easily rotates the atress, makes things convenient for rotatory fastening, has consequently taken into account the convenience of installation and the reliability of connection simultaneously, has good practicality.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
