Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve with good sealing performance. Background Art

[0002] A ball valve is a common type of valve that uses a hollow rotating sphere to control the flow of fluid. A ball valve usually consists of a sphere and two pipe connection ports. There is a hole or channel inside the sphere. When the sphere is aligned with the pipe port, the fluid can flow through the pipe; when the sphere rotates and the hole is not aligned with the pipe port, the passage of the fluid is blocked. The main advantages of a ball valve are simple operation, good sealing and fast switching capabilities. By rotating the sphere, the flow of fluid can be quickly opened or closed. Therefore, ball valves are widely used in situations where fluid flow needs to be quickly cut off. In addition, ball valves have good sealing performance and can effectively prevent fluid leakage. Ball valves are commonly used in liquid and gas control systems, especially in industrial fields. They can be installed on pipelines to regulate flow or cut off fluid flow. Ball valves can also be manually operated as needed or used in conjunction with automated control systems.

[0003] A Chinese patent application number CN218883060U was found, which discloses a leak-proof ball valve, comprising a valve body, a valve core movably connected to the interior of the valve body, a valve stem fixedly connected to the top of the valve core, a packing fixedly connected to the interior of the valve body, a sealing ring fixedly connected to the interior of the valve body, a butt joint fixedly connected to the outer wall of the butt joint, a fixing block fixedly connected to the outer wall of the butt joint, a ring groove formed on one side of the fixing block, a sealing gasket fixedly connected to the interior of the fixing block, and a ring block movably connected to the interior of the ring groove. The leak-proof ball valve can achieve good installation efficiency, improve the installation efficiency of the pipeline and the ball valve, and at the same time, hide the installation to avoid oxidation of the mounting parts, which increases the difficulty of subsequent disassembly, and effectively improve the sealing between the pipeline and the ball valve, indirectly improving the leak-proof performance of the ball valve, thereby improving the practicality of the ball valve to a certain extent. However, this method has the disadvantage that the connection of the ball valve is fixed by bolts, which are prone to rust during long-term use. When disassembly and maintenance are required, it is difficult to disassemble quickly, which cannot meet the needs of use. Utility Model Content

[0038] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment of a ball valve with good sealing performance, comprising a left connecting pipe 1, an external sheet 8 fixedly connected to the right side of the left connecting pipe 1, a fixing ring 7 fixedly connected to the four corners of the outer wall of the external sheet 8, a plug 5 engaged with the inner side of the fixing ring 7, a through hole 6 is opened on the outer wall of the plug 5, an insertion rod 10 is passed through the inner side of the through hole 6, a hollow column 9 is engaged with the rear end of the insertion rod 10, and a filter mechanism 2 is installed on the right side of the left connecting pipe 1;

[0039] Specifically, first take the left connecting pipe 1 and the right connecting pipe 206, and align the two external pieces 8; this step is the basis of the entire installation process, and the accuracy of the alignment directly affects the use effect of the ball valve; therefore, during operation, it is necessary to ensure that the two connecting pipes are placed in the correct position, and the surface of the connecting pipes must also be kept clean to avoid dirt affecting the alignment effect; next, take the plug 5, and pass it through the two fixing rings 7 to limit the aligned position; this step is to ensure that the aligned state of the connecting pipes will not shift during subsequent operations; the penetration force of the plug 5 should be moderate, both to ensure the stability of the fixing ring 7 and to avoid damage to the connecting pipes; then, merge the left connecting pipe 1 and the right connecting pipe 206; in this step, it is necessary to pay attention to whether the interface of the connecting pipe is tight to ensure that during use There will be no leakage or other problems; after the merger is completed, take the insertion rod 10 and pass it through the two through holes 6 in turn; the penetration force of the insertion rod 10 should also be moderate, which is necessary to ensure the stability of the through hole 6 and avoid causing excessive pressure on the connecting pipe; then, take the hollow column 9, insert the end of the insertion rod 10 to limit and fix it; this step is to ensure the stability of the ball valve after installation, and the hollow column 9 must be inserted in place, but not too tight to avoid damaging the connecting pipe; at this point, the combined installation of the ball valve is completed; when disassembly is required, pull out the hollow column 9, and at the same time, pull out the insertion rod 10 and the plug 5 in turn; in this step, pay attention to the force when pulling out the hollow column 9 and pulling out the insertion rod 10 and the plug 5 to avoid damage to the connecting pipe; through this disassembly method, quick disassembly can be achieved, saving time and energy.

[0040] Reference Figure 1 and Figure 4 The filtering mechanism 2 includes a right connecting pipe 206, which is mounted on the right end of the left connecting pipe 1. The upper and lower sides of the inner wall of the right connecting pipe 206 are fixedly connected with a fixed column 201. The right side of the inner wall of the fixed column 201 is fixedly connected with a spring 202. The left end of the spring 202 is fixedly connected with a sliding column 203. A placement rod 204 is installed on the left side of the sliding column 203, and a filter disc 205 is installed on the outer side of the placement rod 204.

The upper and lower sides of the inner wall of the fixed column 201 are provided with a slide groove 15, and the slider 14 is slidably connected to the corresponding slide groove 15 respectively. The filter disc 205 and the inner side of the right connecting pipe 206 adopt a chimeric design.

[0041] Specifically, in the process of water flowing through the filter disc 205, the spring 202 is affected by the impact force of the water flow, thereby achieving preliminary filtration of the water flow; at the same time, the movement of the spring 202 drives the slide post 203 to retract, and this process helps to further purify the water quality; in the process of retraction, the slide post 203 drives the slider 14 to slide smoothly in the slide groove 15, thereby achieving limited control of the water flow; the movement trajectory of the slide post 203 has been carefully planned, which can effectively buffer the impact force of the water flow and prevent the filter disc 205 from being deformed due to excessive impact; this design makes the filter disc 205 more stable and reliable when filtering water quality, greatly improving the filtering effect; when the filter disc 205 needs to be removed for cleaning or replacement, it only needs to be removed from the placement rod 204; the design of the placement rod 204 not only facilitates the installation and disassembly of the filter disc 205, but also provides stable support for the filter disc 205 when it is working.

[0042] Reference Figure 1 and Figure 3 A handle 4 is installed on the top of the right connecting pipe 206; a connecting flange 3 is installed on the right end of the right connecting pipe 206 and the left end of the left connecting pipe 1; a plug ring 11 is fixedly connected to the right side of the outer wall of the left connecting pipe 1, and a slot 12 is opened on the left side of the outer wall of the right connecting pipe 206, and the plug ring 11 is engaged with the slot 12; a sealing ring 13 is installed on the adjacent side of the right connecting pipe 206 and the left connecting pipe 1;

[0043] Specifically, the flow rate and opening and closing of the water source are controlled by the handle 4, the external water source pipeline is connected through the connecting flange 3, and the sealing performance of the ball valve is effectively increased by the engagement of the plug ring 11 and the slot 12, and the sealing performance of the ball valve is further increased by the cooperation of the sealing ring 13.

[0044] Working principle: take the left connecting pipe 1 and the right connecting pipe 206 to align the two external pieces 8, take the plug 5 to penetrate the two fixing rings 7 to limit the aligned position, thereby merging the left connecting pipe 1 and the right connecting pipe 206. After the merging is completed, take the plug 10 and pass it through the two through holes 6 in sequence, and at the same time take the hollow column 9 and insert it into the end of the plug 10 to limit and fix it, completing the combined installation of the ball valve. When disassembly is required, pull out the hollow column 9, and at the same time, pull out the plug 10 and the plug 5 in sequence. It can be disassembled quickly, which is more time-saving and labor-saving, can meet the needs of use, and can be used when water flows through the filter When the filter disc 205 is in the air, the impact force of the water flow causes the spring 202 to be stressed, and at the same time, the spring 202 drives the slide post 203 to retract, and drives the slider 14 to slide in the slide groove 15 while the slide post 203 moves, which is used for position limiting work when the slide post 203 moves. At the same time, the movement trajectory of the slide post 203 is planned, which can effectively buffer and release the impact force of the water flow, thereby avoiding deformation of the filter disc 205 caused by the impact of the water flow. When the filter disc 205 needs to be removed, the filter disc 205 can be removed from the placement rod 204. The water source can be effectively filtered through the placement rod 204, which brings convenience to use.
