Description

Technical Field

[0001] The invention relates to the technical field of valves, in particular to a steel plug valve that can be quickly assembled and disassembled. Background Art

[0002] The plug valve is a valve with a long history and widespread application. Its core component is a conical plug, which is rotated to control the flow of fluids or adjust the flow rate. Plug valves offer advantages such as simple structure, easy operation, excellent sealing performance, and low fluid resistance. They are widely used in various fields, including petroleum, chemical, natural gas, and water treatment.

[0003] Traditional plug valves are typically connected to pipelines using threaded or flanged connections. While this connection method meets basic sealing and securing requirements, in actual use, installation and removal are cumbersome and time-consuming, especially when the plug valve needs to be frequently disassembled or replaced. For example, threaded connections require precise thread alignment and tightening turn by turn, while flange connections require the installation of multiple bolts to ensure uniform force. These operations require specialized tools and the collaboration of multiple personnel, resulting in complex procedures that can easily lead to problems such as poor sealing or loose connections due to improper operation.

[0004] A steel plug valve with quick assembly and disassembly is proposed for this reason. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems mentioned in the above background technology, and to provide a steel plug valve that can be quickly assembled and disassembled.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A quick-assemble and disassemble steel plug valve includes a plug valve body, with connecting pipes fixedly connected to both left and right ends of the plug valve body, a docking sleeve movably sleeved on the surface of the connecting pipe, a lateral adjustment mechanism provided on the surface of the docking sleeve, a supporting mechanism fixedly connected to the surface of the plug valve body, a locking assembly provided on the surface of the supporting mechanism, and a sealing ring fixedly connected to the inner wall of the docking sleeve.

[0007] Furthermore, the lateral adjustment mechanism includes a mounting bracket, and the mounting bracket is fixedly connected to the top of the connecting pipe. The surface of the mounting bracket is rotatably connected to a threaded rod, the surface of the threaded rod is threadedly connected to a connecting block, and the connecting block is fixedly connected to the docking sleeve. The lateral adjustment mechanism also includes an adjustment component for controlling the rotation of the threaded rod.

[0008] Furthermore, the adjustment assembly includes a worm, and the worm is rotatably connected to the mounting frame, the top end of the worm is fixedly connected to a knob, the surface of the threaded rod is fixedly sleeved with a worm wheel, and the worm wheel is engaged with the worm.

[0009] Furthermore, a sliding rod is fixedly connected to the surface of the plug valve body, and the sliding rod is fixedly connected to the connecting pipe. A sliding sleeve is fixedly connected to the surface of the docking sleeve, and the inner wall of the sliding sleeve is movably connected to the sliding rod.

[0010] Furthermore, the support mechanism includes a mounting rod, and the mounting rod is fixedly connected to the plug valve body, the end of the mounting rod is fixedly connected to the support seat, the surface of the mounting rod is movably plugged with the support rod, the top of the support rod is fixedly connected to the mounting plate, the bottom surface of the mounting plate is fixedly connected to the pressure block, and the opposite sides of the pressure block and the support seat are fixedly connected to shock-absorbing pads.

[0011] Furthermore, the locking assembly includes a mounting groove, and the mounting groove is opened inside the support rod. The inner wall of the mounting groove is fixedly connected to a spring, the free end of the spring is fixedly connected to an insert block, and the insert block is movably connected to the support rod, and the end of the insert block is a slope structure that is wide at the top and narrow at the bottom.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention realizes the rapid installation and disassembly of the plug valve by cooperating with the lateral adjustment mechanism and the locking assembly. During the installation process, the operator does not need to use complicated tools, but can drive the worm and worm wheel by manually turning the knob, thereby driving the threaded rod to rotate, pushing the docking sleeve to accurately dock the pipeline, and quickly fix it through the locking assembly. When disassembling, the reverse operation can be easily completed. The present invention significantly reduces the time and manpower required for loading and unloading. Compared with the traditional threaded or flange-connected plug valves, the loading and unloading efficiency is greatly improved. It is particularly suitable for working conditions that require frequent replacement or maintenance of plug valves. It can effectively shorten equipment downtime and improve production efficiency.

[0013] 2. The support mechanism and locking assembly of the present invention work together to provide reliable stability for the connection between the plug valve and the pipeline. The pressure block and support seat in the support mechanism are in contact with the pipeline through the shock-absorbing pad, which can not only firmly clamp the pipeline, but also effectively absorb the vibration generated by the pipeline during operation, preventing the connection from loosening due to vibration. At the same time, the spring and plug structure in the locking assembly can ensure that the support rod remains stable after being fixed, further enhancing the connection strength between the plug valve and the pipeline. This stable connection method effectively avoids the leakage problem caused by poor sealing or loose connection of traditional plug valves, and improves the operational safety and reliability of the pipeline system.

[0019] like Figures 1 to 4As shown, a quick-assemble and disassemble steel plug valve includes a plug valve body 1, with connecting pipes 2 fixedly connected to the left and right ends of the plug valve body 1, a docking sleeve 3 movably sleeved on the surface of the connecting pipe 2, a lateral adjustment mechanism 4 is provided on the surface of the docking sleeve 3, a supporting mechanism 5 is fixedly connected to the surface of the plug valve body 1, a locking assembly 6 is provided on the surface of the supporting mechanism 5, and a sealing ring 7 is fixedly connected to the inner wall of the docking sleeve 3. More specifically, the docking sleeve 3 is aligned with the pipeline to be connected, and the lateral adjustment mechanism 4 is operated to control the docking sleeve 3 to move toward the end of the pipeline, so that the docking sleeve 3 is inserted into the end of the pipeline, and the inner wall of the docking sleeve 3 and the outside of the pipeline are sealed by the sealing ring 7. Then, the locking component 6 is operated to make the supporting mechanism 5 close to the surface of the pipeline, supporting and limiting the pipeline, and the plug valve body 1 can be smoothly installed and connected to the pipeline. The plug valve body 1 can be quickly disassembled by reverse operation. The present invention achieves the effect of facilitating quick disassembly and installation of the plug valve during use. No other special tools are required during the loading and unloading process, making the installation process easier and more labor-saving, thereby improving the loading and unloading efficiency of the plug valve.

[0020] The transverse adjustment mechanism 4 includes a mounting bracket 401, which is fixedly connected to the top of the connecting pipe 2. A threaded rod 404 is rotatably connected to the surface of the mounting bracket 401. A connecting block 406 is threadedly connected to the surface of the threaded rod 404. The connecting block 406 is fixedly connected to the docking sleeve 3. The transverse adjustment mechanism 4 also includes an adjustment assembly for controlling the rotation of the threaded rod 404. It should be noted that the adjustment assembly controls the rotation of the threaded rod 404, and under the action of the threads, the connecting block 406 is driven to move, thereby pushing the docking sleeve 3 to move, so that the inner wall of the docking sleeve 3 docks with the pipeline, thereby connecting the plug valve body 1 to the pipeline.

[0021] The adjustment assembly includes a worm 402, which is rotatably connected to a mounting bracket 401. A knob 403 is fixedly connected to the top of the worm 402. A worm gear 405 is fixedly sleeved on the surface of a threaded rod 404, and the worm gear 405 meshes with the worm 402. More specifically, by turning the knob 403, the worm 402 rotates, which in turn rotates the meshed worm gear 405, thereby controlling the rotation of the threaded rod 404.

[0022] A sliding rod 407 is fixedly connected to the surface of the plug valve body 1, and the sliding rod 407 is fixedly connected to the connecting pipe 2. A sliding sleeve 408 is fixedly connected to the surface of the docking sleeve 3, and the inner wall of the sliding sleeve 408 is movably connected to the sliding rod 407. It should be noted that when the docking sleeve 3 moves, it drives the sliding sleeve 408 to slide along the surface of the sliding rod 407, supporting and guiding the docking sleeve 3, so that the docking sleeve 3 can remain stable.

[0023] The support mechanism 5 includes a mounting rod 501, which is fixedly connected to the plug valve body 1. The end of the mounting rod 501 is fixedly connected to a support seat 503. A support rod 505 is movably connected to the surface of the mounting rod 501. The top of the support rod 505 is fixedly connected to the mounting plate 502. The bottom surface of the mounting plate 502 is fixedly connected to a pressure block 504. The pressure block 504 and the opposite side of the support seat 503 are fixedly connected to a shock-absorbing pad 506. More specifically, during installation, the support seat 503 supports the bottom of the pipeline. By sliding the mounting plate 502 downward, the support rod 505 and the pressure block 504 are driven down, causing the pressure block 504 to press the surface of the pipeline. Subsequently, the support rod 505 is fixed by the locking assembly 6, thereby clamping and fixing the pipeline and providing support for the pipeline. At the same time, the shock-absorbing pad 506 can absorb any vibration that may be generated by the pipeline, further improving the stability of the pipeline connection.

[0024] The locking assembly 6 includes a mounting slot 601, which is defined within the support rod 505. A spring 602 is fixedly connected to the inner wall of the mounting slot 601. The free end of the spring 602 is fixedly connected to an insert 603, which is movably connected to the support rod 505. The end of the insert 603 has an inclined surface structure that is wider at the top and narrower at the bottom. It should be noted that pressing the support rod 505 downward causes the insert 603 to contact the top surface of the mounting rod 501, thereby pushing the insert 603 back into the mounting slot 601 and compressing the spring 602. After the insert 603 passes through the hole in the surface of the mounting rod 501, the elastic force of the spring 602 pushes the insert 603 back into place, thereby stabilizing the support rod 505 and the pressure block 504, thereby supporting and limiting the pipeline.

[0025] In summary: align the docking sleeve 3 with the pipeline to be connected, operate the lateral adjustment mechanism 4, control the docking sleeve 3 to move toward the end of the pipeline, so that the docking sleeve 3 is inserted into the end of the pipeline, and the inner wall of the docking sleeve 3 and the outside of the pipeline are sealed by the sealing ring 7, and then the locking component 6 is operated to make the supporting mechanism 5 close to the surface of the pipeline, support and limit the pipeline, and the plug valve body 1 can be smoothly installed and connected to the pipeline, and the plug valve body 1 can be quickly disassembled by reverse operation. The present invention achieves the effect of facilitating quick disassembly and installation of the plug valve during use, and no other special tools are required during the loading and unloading process, making the installation process easier and more labor-saving, thereby improving the loading and unloading efficiency of the plug valve.
