Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a ball valve that is easy to disassemble and maintain. Background Technology

[0002] In industrial fluid control systems, ball valves, as a key shut-off or regulating device, are widely used in petroleum, chemical, natural gas, and water treatment industries. Their core structure uses a rotating ball to open and close the flow path, offering advantages such as flexible operation and reliable sealing. However, during long-term operation, traditional ball valves often experience problems such as aging of seals, valve stem jamming, and valve body corrosion due to media corrosion, high-temperature and high-pressure environments, or frequent opening and closing operations. This can lead to valve leakage or failure to open and close normally. Such malfunctions not only affect production efficiency but may also pose safety hazards.

[0003] Traditional ball valve maintenance typically requires complete disassembly, sometimes even necessitating the disconnection of the piping system. This process is complex and time-consuming. For example, the valve body is often connected to the pipeline via flanges or welding, requiring specialized tools and damaging parts of the structure during disassembly, increasing maintenance costs and downtime. Furthermore, some ball valves have compact internal structures, making seal replacement difficult and hindering maintenance personnel from operating within confined spaces, further reducing efficiency. While existing ball valves with easy-to-disassemble designs facilitate disassembly, sealing remains paramount during overall use. Although disassembly is convenient, a certain level of sealing is still required during repeated disassembly and installation. Current ball valves still rely on traditional seals, which significantly reduce sealing performance with repeated disassembly and installation. Therefore, a ball valve designed for easy disassembly and maintenance is proposed. Summary of the Invention

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] Please see Figures 1-5 This utility model provides a technical solution: a ball valve that is easy to disassemble and maintain, comprising: a left valve body 1 and a right valve body 2, a valve core 3 connected at the center of the left valve body 1 and the right valve body 2, a rigid snap-fit ​​sleeve 5 integrally formed on the side of the left valve body 1 near the right valve body 2, an inner insertion groove 6 integrally formed on the side of the right valve body 2 near the left valve body 1, the rigid snap-fit ​​sleeve 5 being inserted into the inner insertion groove 6, the valve core 3 being located at the center of the rigid snap-fit ​​sleeve 5 and the inner insertion groove 6, a fixed sealing assembly being fixedly connected to the outside of the rigid snap-fit ​​sleeve 5, and a sealing sleeve 4 integrally formed on the outside of the right valve body 2.

[0024] In this embodiment, specifically: during use, the ball valve is divided into a left valve body 1 and a right valve body 2. The left valve body 1 and the right valve body 2 are connected by a rigid snap-fit ​​sleeve 5 and an inner insertion groove 6, which facilitates the disassembly and maintenance of the left valve body 1 and the right valve body 2. After the rigid snap-fit ​​sleeve 5 is inserted into the inner insertion groove 6, a connection can be formed between the left valve body 1 and the right valve body 2. Furthermore, after the rigid snap-fit ​​sleeve 5 is inserted into the inner insertion groove 6, the connection stability between the left valve body 1 and the right valve body 2 can be further enhanced by the shaping and sealing assembly, and the sealing effect between the left valve body 1 and the right valve body 2 can be enhanced by the shaping and sealing assembly.

[0025] like Figures 2-4 As shown, the shaping and sealing assembly includes a rubber seat 16, which is fixedly connected to the outer wall of the rigid snap sleeve 5. The rubber seat 16 has an integrally formed wear-resistant storage bladder 10 on its exterior. The wear-resistant storage bladder 10 is filled with high-temperature resistant paraffin wax 11, and a heating wire 12 is connected through the interior of the wear-resistant storage bladder 10.

[0026] In this embodiment, specifically: in the shaped sealing structure, when the rigid snap-fit ​​sleeve 5 is inserted into the inner layer snap-fit ​​groove 6 to form a preliminary connection, high-temperature resistant paraffin wax 11 can also be pre-filled into the wear-resistant storage bladder 10. When the high-temperature resistant paraffin wax 11 is still in liquid state, it is inserted into the inner layer snap-fit ​​groove 6 together with the rigid snap-fit ​​sleeve 5. After the connection is completed, the high-temperature resistant paraffin wax 11 gradually cools down. Under the condition of gradual cooling, a secondary seal can be formed inside the inner layer snap-fit ​​groove 6. An interlocking groove matching the shape of the wear-resistant storage bladder 10 is opened inside the inner layer snap-fit ​​groove 6. After the wear-resistant storage bladder 10 is snapped into the interlocking groove, a multi-level snap-fit ​​can be formed, which further enhances the connection stability and sealing between the left valve body 1 and the right valve body 2.

[0027] like Figure 4 As shown, the sealing assembly also includes a secondary storage bladder 13, which is integrally formed on the outside of the wear-resistant storage bladder 10, and the interior of the secondary storage bladder 13 is filled with hot melt adhesive 14.

[0028] In this embodiment, specifically: after the wear-resistant storage capsule 10 and the high-temperature resistant paraffin wax 11 are inserted into the inner layer insertion groove 6, hot melt adhesive 14 can be injected into the interior of the secondary storage capsule 13. When the hot melt adhesive 14 expands, it can fill the space inside the fitting groove again, further enhancing the sealing effect.

[0029] like Figure 5As shown, a placement groove 20 is provided on the left valve body 1. A feed valve pipe 17 is installed inside the placement groove 20. The air outlet of the feed valve pipe 17 is connected to the secondary storage bladder 13. An external power supply connector 18 is connected inside the placement groove 20. The power supply end of the external power supply connector 18 passes through the outer wall of the left valve body 1 and is connected to the heating wire 12. A sealing plug 19 is snapped into the inside of the placement groove 20.

[0030] In this embodiment, specifically: when separating the left valve body 1 and the right valve body 2, an external power supply can be connected to the external power supply connector 18. After connecting the external power supply to the external power supply connector 18, the external power supply connector 18 gradually generates heat. As the external power supply connector 18 gradually generates heat, the high-temperature resistant paraffin wax 11 and the hot melt adhesive 14 melt. When the high-temperature resistant paraffin wax 11 and the hot melt adhesive 14 melt, they no longer provide rigid support to the wear-resistant storage bladder 10 and the secondary storage bladder 13. Therefore, the operator... When pulling the left valve body 1 and the right valve body 2 outward, only a little force is needed to separate the left valve body 1 and the right valve body 2. At the same time, when the left valve body 1 and the right valve body 2 are reconnected, hot melt adhesive 14 can be re-injected into the interior of the secondary storage bladder 13 through the feed valve pipe 17. The hot melt adhesive 14 refills the gap between the rigid snap sleeve 5 and the inner insertion groove 6, further reducing leakage. When the feed valve pipe 17 and the external power connector 18 are not needed, the sealing plug 19 is inserted into the interior of the placement groove 20 to complete the sealing of the placement groove 20.

[0031] like Figure 3 and Figure 4 As shown, a magnet 15 is fixedly connected to the side of the rigid snap-fit ​​sleeve 5 away from the left valve body 1. When the rigid snap-fit ​​sleeve 5 is snapped into the inner insertion slot 6, the right valve body 2 can also be attracted by the magnet 15, further enhancing the connection stability.

[0032] like Figure 1 and Figure 2 As shown, multiple plug-in pins 7 are provided on the outside of both the left valve body 1 and the right valve body 2. Threaded rods 8 are connected to the inside of the plug-in pins 7. Multiple bolts 9 are fixedly connected to the outside of each threaded rod 8. The bolts 9 are located on opposite sides of the left valve body 1 and the right valve body 2. A lever handle 21 is integrally formed on the outside of each bolt 9.

[0033] In this embodiment, specifically: during use, after the rigid snap-fit ​​sleeve 5 and the inner insert groove 6 form a snap-fit, multiple threaded rods 8 need to be threaded into the interior of the insert post 7, and bolts 9 need to be threaded to the opposite sides of the left valve body 1 and the right valve body 2 respectively, thereby forming a fixation on the outside to ensure the connection stability of the left valve body 1 and the right valve body 2. At the same time, the bolts 9 can be tightened and loosened by the lever 21 integrally formed on the outside of the bolts 9.

[0034] Working principle: The separate design of the left valve body 1 and the right valve body 2 facilitates maintenance. During assembly, the rigid snap-fit ​​sleeve 5 of the left valve body 1 is inserted into the inner insertion groove 6 of the right valve body 2. The magnet 15 is used to attract and enhance the initial connection stability. At the same time, the valve core 3 is automatically centered to the center of the fluid channel. Then, the threaded rod 8 passes through the insertion post 7 and is mechanically locked by bolts 9 and the lever 21. During the sealing enhancement stage, liquid high-temperature resistant paraffin 11 is injected into the wear-resistant storage bladder 10 through the feed valve pipe 17. After the snap-fit ​​sleeve is inserted, the paraffin cools and solidifies. A primary rigid seal is formed, and then hot melt adhesive 14 is injected into the secondary storage bladder 13. The adhesive expands and fills the interlocking groove to achieve a secondary flexible seal. During disassembly, the heating wire 12 is heated by connecting to the external power connector 18, which melts the high-temperature resistant paraffin wax 11 and hot melt adhesive 14. After the rigid support of the sealing material is released, the valve body can be separated. After maintenance, the sealing material can be re-injected through the feed valve pipe 17 to restore the sealing performance. The entire process is protected by the sealing plug 19 to ensure both the stability of the valve body connection and the sealing, enabling quick disassembly and reuse.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
