Description

Technical Field

[0001] This utility model relates to the field of loading arms technology, and in particular to a corrosion-resistant fluid loading arm. Background Technology

[0002] Loading arms are the main equipment used in the fluid loading and unloading process. Currently, a liquid phase loading arm is mainly composed of a column, a horizontal pipe, a vertical pipe, a rotary joint, and a torque balancing device. A loading arm with oil and gas recovery function is based on the above liquid phase loading arm structure with the addition of a gas phase loading arm with a basically the same structure.

[0003] A search revealed that Chinese Patent Publication No. CN219409253U discloses a cantilever-type fully automatic loading and unloading arm. This technical solution involves pulling a tension column, which in turn pulls a limiting block, further stretching the spring upwards. Simultaneously, one end of the tension column separates from the slot, allowing the arm to be pulled downwards, enabling the fixing block to slide out of the mounting groove and thus disassembling the arm.

[0004] However, the above-mentioned technical solutions require both tensioning columns to be pulled out of the slots before disassembling the loading arm, which is cumbersome. Furthermore, during installation, it's impossible to ensure a tight fit between the loading arm and the connecting pipe, leading to fluid leakage at the gaps and waste, resulting in poor performance. Therefore, this invention proposes a corrosion-resistant fluid loading arm to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing a corrosion-resistant fluid loading and unloading arm.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corrosion-resistant fluid loading arm, comprising:

[0008] Connecting pipe;

[0009] The loading arm is detachably installed at the end of the connecting pipe;

[0010] The connecting assembly includes a retaining ring fixedly mounted on the surface of the loading arm, an externally threaded tube fixedly mounted on the surface of the connecting tube, an internally threaded ring threadedly connected to the surface of the externally threaded tube, and two right-angle positioning rods fixedly mounted on one end of the internally threaded ring near the loading arm, wherein the two right-angle positioning rods are symmetrically arranged about the center of the internally threaded ring and are distributed on the same straight line.

[0011] A positioning component is used to limit the loading arm to the end of the connecting pipe.

[0012] Preferably, the positioning component includes multiple positioning blocks fixedly installed on the end of the connecting pipe near the loading arm, and the positioning blocks slide through the end of the fixing ring. The surface of the fixing ring is provided with multiple positioning holes, and the multiple positioning holes and multiple positioning blocks are matched and distributed circumferentially.

[0013] Preferably, a rubber sealing ring is fixedly installed at one end of the connecting pipe near the loading arm.

[0014] Preferably, the internal threaded ring has multiple protrusions fixedly installed on its side, and the multiple protrusions are circumferentially distributed.

[0015] Preferably, the surface of each positioning block is coated with a rubber layer.

[0016] Preferably, the thickness of each positioning block is equal to the thickness of the fixing ring.

[0017] Compared with existing technologies, the advantages of the corrosion-resistant fluid loading arm provided by this utility model are as follows:

[0018] 1. Before connection, align each positioning hole 8 on the fixing ring 3 with each positioning block 7, and then put it on. This will initially fix the loading arm 2 to the end of the connecting pipe 1 when installing the loading arm 2, without the need for manual handling, which is convenient.

[0019] 2. By rotating the internal threaded ring clockwise and counterclockwise, the two right-angle positioning rods can move away from and closer to the fixing ring on the surface of the loading arm. When moving away from the fixing ring, the loading arm can be quickly disassembled and assembled. Conversely, when moving closer to the fixing ring, the end of the loading arm can be tightly pressed against the surface of the rubber sealing ring, thus completing the installation of the loading arm and the connecting pipe. At the same time, the sealing of the connection between the connecting pipe and the loading arm is ensured, so as to avoid fluid leakage at the gap between the connecting pipe and the loading arm, which would cause waste and improve the efficiency of the device.

[0020] In summary, this utility model enables quick and easy assembly and disassembly of the connecting pipe and the loading arm by rotating the internal threaded ring in both directions. Furthermore, during installation, it ensures a tight seal at the connection point between the connecting pipe and the loading arm, preventing fluid leakage and waste, thus improving the overall performance of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1 to 3 A corrosion-resistant fluid loading arm, comprising:

[0027] Connecting pipe 1; Loading arm 2, detachably installed at the end of connecting pipe 1; a rubber sealing ring 9 is fixedly installed at the end of connecting pipe 1 near loading arm 2, which further increases the sealing between connecting pipe 1 and loading arm 2 when they are connected.

[0028] The connecting assembly includes a retaining ring 3 fixedly mounted on the surface of the loading arm 2, an externally threaded pipe 4 fixedly mounted on the surface of the connecting pipe 1, an internally threaded ring 5 threadedly connected to the surface of the externally threaded pipe 4, and multiple protrusions 10 fixedly mounted on the side of the internally threaded ring 5, and the multiple protrusions 10 are circumferentially distributed, so that the user can more easily rotate the internally threaded ring 5.

[0029] Two right-angle positioning rods 6 are fixedly installed at one end of the internal threaded ring 5 near the loading arm 2, and the two right-angle positioning rods 6 are symmetrically arranged about the center of the internal threaded ring 5 and are distributed in the same straight line:

[0030] A positioning assembly is used to limit the loading arm 2 to the end of the connecting pipe 1. The positioning assembly includes multiple positioning blocks 7 fixedly installed on the end of the connecting pipe 1 near the loading arm 2, and the positioning blocks 7 slide through the end of the fixing ring 3. The surface of the fixing ring 3 has multiple positioning holes 8, and the multiple positioning holes 8 and multiple positioning blocks 7 are matched and distributed circumferentially. Before connection, each positioning hole 8 on the fixing ring 3 is aligned with each positioning block 7, and then it is put on. This can initially fix the loading arm 2 to the end of the connecting pipe 1 when installing the loading arm 2. The surface of each positioning block 7 is coated with a rubber layer, which can increase the friction between the positioning block 7 and the positioning hole 8 after the fixing ring 3 is put on each positioning block 7, so that the loading arm 2 is not easy to fall off the positioning block 7 when it is not fixed, and it can also prevent the loading arm 2 from rotating. The thickness of each positioning block 7 is equal to the thickness of the fixing ring 3, which can prevent the positioning block 7 from protruding from the positioning hole 8 and hindering the rotation of the right angle positioning rod 6.

[0031] The working principle of this utility model is as follows:

[0032] When using, during disassembly, rotate the internal threaded ring 5 to make the two right-angle positioning rods 6 spiral downwards and move away from the fixing ring 3. Then, pull out a section of the loading arm 2 downwards and directly move out the two right-angle positioning rods 6 horizontally to quickly complete the disassembly of the loading arm 2.

[0033] During installation, first move the fixing ring 3 horizontally between the two right-angle positioning rods 6. Then, align each positioning hole 8 on the fixing ring 3 with each positioning block 7 and put it on to initially position the loading arm 2. Finally, rotate the internal threaded ring 5 in the opposite direction to drive the two right-angle positioning rods 6 to move upwards spirally until they contact the end of the fixing ring 3 and press their ends tightly against the surface of the rubber sealing ring 9. This completes the installation of the loading arm 2 and the connecting pipe 1, while ensuring the sealing of the connection between the connecting pipe 1 and the loading arm 2 to avoid fluid leakage at the gap between the connecting pipe 1 and the loading arm 2, thus improving the efficiency of the device.

[0034] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
