Description

Technical Field

[0001] This utility model belongs to the field of pipeline connector technology, specifically a sealing connector for oil storage and transportation pipelines. Background Technology

[0002] Oil pipeline systems, used to transport petroleum and petroleum products, mainly consist of pipelines, pumping stations, and other auxiliary equipment. They are one of the key pieces of equipment in the petroleum storage and transportation industry, and the most important transportation method for crude oil and petroleum products. Compared to rail and road oil transportation, which are also land-based modes, pipeline transportation offers advantages such as larger capacity, better sealing, lower cost, and higher safety. Oil pipelines are generally made of steel pipes, connected by welding and flanges to form long pipelines, and valves are used for opening and closing control and flow regulation. Oil pipelines utilize various transportation processes, including isothermal transport, heated transport, and sequential transport. Currently, oil pipelines have become one of the main means of transporting petroleum and continue to have considerable development potential in the future. Sealing connectors are required in oil storage and transportation pipelines to seal the connections between pipes, improving overall sealing and safety.

[0003] Existing patent document CN215617840U discloses a sealing connector for oil storage and transportation pipelines, relating to the field of oil transportation technology. Specifically, it includes a support plate and a base. A connecting rod is hinged to one side of the support plate, and a snap-fit ​​rod is fixedly connected to the bottom end of the connecting rod. A threaded rod is threaded to the middle of the support plate, and an arc-shaped plate is rotatably connected to the bottom end of the threaded rod. A sliding block is sleeved on the outer surface of the connecting rod, and a connecting plate is hinged to one side of the sliding block. A transmission plate is fixedly connected to one side of the connecting plate, and a transmission screw is threaded to one side of the transmission plate. A circular plate is fixedly connected to the other end of the transmission screw. Through the coordinated arrangement of the base, connecting rod, snap-fit ​​rod, threaded rod, and arc-shaped plate, the position of the arc-shaped plate can be adjusted according to the diameter of the storage and transportation pipeline during use. This achieves the purpose of quickly clamping and fixing storage and transportation pipelines of various diameters, resulting in a simple structure, improved clamping and fixing effect, and wide applicability.

[0004] However, existing oil storage and transportation pipeline sealing connectors have poor compatibility due to the varying diameters of oil storage and transportation pipelines. Different diameter oil storage and transportation pipelines require different connector models. Furthermore, during the connection process, the two pipelines to be connected are placed on a fixed base or bracket to ensure that the pipeline ends are aligned and the gap between the pipeline ends is adjusted before installation can proceed. This method is not only difficult to install but also inconvenient to disassemble.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a sealing connector for oil storage and transportation pipelines. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a sealing connector for oil storage and transportation pipelines, which solves the problems of poor compatibility, difficult installation, and inconvenient disassembly of existing pipeline sealing connectors.

[0007] A sealing connector for an oil storage and transportation pipeline includes a fixing unit and a sealing connection unit. The fixing unit includes an adjusting seat, a forward lead screw is movably connected through the front of the adjusting seat, a reverse lead screw is fixedly connected to one end of the forward lead screw, a fixing bracket is fixedly connected to the top of the adjusting seat, an adjusting screw is threaded through the top of the fixing bracket, a movable sleeve is movably connected to the bottom of the adjusting screw, a fixing clamp is fixedly connected to the bottom of the movable sleeve, and an adjusting groove is provided at the center of the top of the adjusting seat.

[0008] The sealing connection unit includes a sliding seat located on the top of the adjusting seat and movably connected via an adjusting groove. A connecting pipe is fixedly connected to the top of the sliding seat, and a sealing ring is fixedly connected to one end of the connecting pipe. An installation groove is provided on the inner wall of the connecting pipe, and a sealing sleeve is installed on the inner wall of the connecting pipe through the installation groove.

[0009] Preferably, both the lead screw and the outer side of the lead screw are threaded with nut seats, and the nut seats are fixedly connected to the sliding seat.

[0010] Preferably, a limiting groove is provided on one side of the fixed bracket, and a fixing seat is installed on the inner side of the fixed bracket.

[0011] Preferably, a limiting slider is fixedly connected to one side of the fixed clamping plate, and the limiting slider is movably connected to the limiting groove.

[0012] Preferably, an adjusting tube is movably connected to the outside of the connecting tube, and both ends of the adjusting tube are threaded with sealing caps.

[0013] Preferably, the sealing sleeve gradually decreases in size from the outside to the inside, and the sealing sleeve is made of rubber material.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its sliding seat, connecting pipe, and adjusting pipe, allows for easy installation and disassembly of the oil storage and transportation pipeline sealing connector. The operator places the two oil storage and transportation pipelines to be connected on the fixed seat, then rotates the adjusting screw. The adjusting screw, through the movable sleeve, moves the fixed clamping plate downwards. At this time, the limiting slider slides through the limiting groove, and the fixed clamping plate and fixed seat fix the oil storage and transportation pipelines. Subsequently, the operator rotates the forward and reverse screws clockwise, causing the nut seat to move the sliding seat outwards through the adjusting groove. Simultaneously, the connecting pipe on the sliding seat engages with the oil storage and transportation pipeline on the fixed seat. As the connecting pipe moves outwards, the sealing sleeve gradually decreases in size from the outside to the inside, resulting in a tighter and tighter fit around the oil storage and transportation pipeline. Disassembly is simple; only the forward and reverse screws need to be rotated in the opposite direction. This facilitates installation and disassembly, allowing the pipeline sealing connector to adapt to various sizes of oil storage and transportation pipelines, thus improving its compatibility.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] Example 1: A sealing connector for oil storage and transportation pipelines includes a fixing unit 1 for fixing the pipeline, including an adjusting seat 101 that serves as a load-bearing element. A forward screw 109 for adjusting a nut seat 111 is movably connected through the front of the adjusting seat 101. A reverse screw 110 for adjusting the nut seat 111 is fixedly connected to one end of the forward screw 109. A fixing bracket 102 for mounting components is fixedly connected to the top of the adjusting seat 101. An adjusting screw 104 for adjusting a fixing clamp 106 is threaded through the top of the fixing bracket 102. A movable sleeve 105 for rotating the adjusting screw 104 is movably connected to the bottom of the adjusting screw 104. A fixing clamp 106 for clamping and fixing the pipeline is fixedly connected to the bottom of the movable sleeve 105. An adjusting groove 112 for limiting the position is provided at the center of the top of the adjusting seat 101.

[0026] Furthermore, both the lead screw 109 and the outer side of the lead screw 109 are threaded with nut seats 111 for driving the sliding seat 201 to move, and the nut seats 111 are fixedly connected to the sliding seat 201.

[0027] Furthermore, a limiting groove 108 is provided on one side of the fixed bracket 102 to limit the position, and a fixing seat 103 for placing the pipe is installed on the inner side of the fixed bracket 102.

[0028] Furthermore, a limiting slider 107 that serves as a limiter is fixedly connected to one side of the fixed clamping plate 106, and the limiting slider 107 is movably connected to the limiting groove 108.

[0029] As can be seen from the above, when using the oil storage and transportation pipeline sealing connector, the staff places the two oil storage and transportation pipelines to be connected on the fixed seat 103 respectively. Then, the staff rotates the adjusting screw 104. The adjusting screw 104 drives the fixed clamp 106 to move downward through the movable sleeve 105. At this time, the limiting slider 107 slides through the limiting groove 108, and the fixed clamp 106 and the fixed seat 103 will fix the oil storage and transportation pipeline.

[0030] Example 2: This example is basically the same as the previous example, except that the sealing connection unit 2 for connecting two pipes includes a sliding seat 201 located on the top of the adjusting seat 101 and movably connected through the adjusting groove 112 for moving the connecting pipe 202. The top of the sliding seat 201 is fixedly connected to the connecting pipe 202 for fitting the pipe. One end of the connecting pipe 202 is fixedly connected to a sealing ring 205 for sealing. The inner wall of the connecting pipe 202 is provided with an installation groove 206 for installing sealing components. A sealing sleeve 207 for sealing the pipe is installed on the inner wall of the connecting pipe 202 through the installation groove 206.

[0031] Furthermore, an adjusting tube 203 is movably connected to the outside of the connecting tube 202 to control the opening and closing of the connecting tube 202. Both ends of the adjusting tube 203 are threaded with sealing caps 204 to provide a sealing function.

[0032] Furthermore, the interior of the sealing sleeve 207 gradually decreases in size from the outside to the inside, and the sealing sleeve 207 is made of rubber material.

[0033] As can be seen from the above, when the operator rotates the forward lead screw 109 and the reverse lead screw 110 clockwise, the nut seat 111 drives the sliding seat 201 to slide outward through the adjusting groove 112. At the same time, the connecting pipe 202 on the sliding seat 201 will be sleeved on the oil storage and transportation pipeline on the fixed seat 103. As the connecting pipe 202 moves outward, the inside of the sealing sleeve 207 gradually becomes smaller from the outside to the inside, so that the sealing sleeve 207 will fit more and more tightly on the oil storage and transportation pipeline, thus completing the installation.
