[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a valve replacement device with air supply, comprising: a tool body 1, and a tool fastener 2 disposed around the tool body 1; a valve body 4, and a tool housing 3 installed inside the valve body 4. The tool fastener 2 is disposed inside the tool housing 3, and one end of the outer side of the tool housing 3 is provided with a second external thread 32 for threaded connection with the valve body 4.

[0025] The tool body 1 includes a rod 11, one end of which is integrally formed with a nut 13, and the outer side of the rod 11 near the nut 13 is provided with a first external thread 12.

[0026] The tool fastener 2 includes a hollow sleeve 21. The inner wall of the hollow sleeve 21 has an internal thread 24 that connects to the first external thread 12. The tool body 1, the fastener, and the tool housing 3 are all made of stainless steel, ensuring the product's corrosion resistance and durability, extending the tool's service life, and maintaining stable performance in various environments. The rod 11 has an external thread design in the middle, which allows the tool to be firmly fixed to the fastener, ensuring the stability and safety of the connection. The internal thread 24 inside the hollow sleeve 21 allows the fastener to be tightly connected to the tool body 1, which not only improves the connection strength but also reduces the overall weight through the hollow structure, improving the ease of operation. The design of the second external thread 32 allows the tool to be tightly connected to the original internal thread 24 of the valve body 4. This design not only facilitates installation but also improves the reliability of the connection.

[0027] A sealing rubber sleeve 5 is fitted on the outer end of the rod 11 away from the nut 13. A tapered groove 23 is provided on the outer end of the hollow sleeve 21. One end of the hollow sleeve 21 abuts against one end of the sealing rubber sleeve 5. The other end of the rod 11 is integrally formed with a top cap 14 that abuts against the sealing rubber sleeve 5. The tapered groove 23 can better fix the sealing rubber sleeve 5 to one end of the hollow sleeve 21, preventing it from shifting or loosening during use. This enhances the stability of the connection between the sealing rubber sleeve 5 and the hollow sleeve 21, further ensuring the reliability of the overall sealing effect and maintaining the good performance of the tool during operation. The top cap 14 not only enhances the overall aesthetics of the tool, but also provides additional protection and support during use.

[0028] The inner diameter of the sealing rubber sleeve 5 is the same as the outer diameter of the rod body 11, and the inner diameter of the hollow sleeve 21 is the same as the inner diameter of the rod body 11, ensuring a tight fit between the two without gaps. This effectively prevents gas from leaking between the rod body 11 and the sealing rubber sleeve 5. Good sealing is crucial in valve replacement operations without interrupting gas supply. This design ensures that gas can only flow within the specified pipeline, improving operational safety, avoiding safety hazards caused by gas leaks, and protecting the lives and property of residents and workers.

[0029] The nut 13 is set in the shape of a hexagonal prism. The outer diameter of the nut 13 is smaller than the inner diameter of the hollow sleeve 21. The hexagonal prism shape of the nut 13 provides users with an interface that is easy to grip and operate, greatly improving the convenience and efficiency of use.

[0030] The outer end of the hollow sleeve 21 away from the tapered groove 23 is integrally formed with a hexagonal groove 22. The outer diameter of the hexagonal groove 22 is smaller than the outer diameter of the hollow sleeve 21, which allows for better force application when using tools such as hexagonal wrenches, thereby improving the accuracy and efficiency of operation and making it easier for users to perform tightening or disassembly operations.

[0031] An annular sealing groove 31 is provided at one end of the inner wall of the tool housing 3. A sealing ring 6 is embedded in the inner cavity of the annular sealing groove 31. The sealing ring 6 is sleeved on the outside of the hollow sleeve 21. The main function of the sealing ring 6 is to prevent gas leakage. During the process of changing valves without stopping the gas supply, gas may seep out from the connection between the tool housing 3 and the hollow sleeve 21. The sealing ring 6 forms a reliable sealing barrier by tightly fitting the annular sealing groove 31 on the inner wall of the housing and the outside of the hollow sleeve 21, effectively preventing gas leakage and ensuring a safe working environment.

[0032] The length of the hollow sleeve 21 is less than the length of the rod 11, and the length of the tool housing 3 is less than the length of the hollow sleeve 21. When installing and connecting with valves and piping systems, the shorter lengths of the tool housing 3 and the hollow sleeve 21 can better adapt to different installation environments and space constraints. For example, in confined spaces, the shorter housing and sleeve will not interfere with each other due to excessive length, facilitating accurate docking of the tool with the valve, improving the convenience and success rate of installation, ensuring that the tool can be installed and used smoothly under various actual working conditions, and enhancing the versatility and applicability of the tool.

[0033] Working principle: When using this utility model to replace a valve while it is in operation, firstly, the tool housing 3 is installed on the valve body 4 through the second external thread 32. Then, the rod 11 with the sealing rubber sleeve 5 is inserted into the hollow sleeve 21. Rotating the nut 13 tightens the rod 11 and the hollow sleeve 21 through the threaded connection. At this time, the sealing rubber sleeve 5 forms a seal under the action of the rod 11, the hollow sleeve 21 and the top cap 14. The sealing ring 6 forms a seal between the tool housing 3 and the hollow sleeve 21, ensuring that the gas will not leak when the device is in operation. The operator can adjust the position of the rod 11 in the hollow sleeve 21 by rotating the nut 13, thereby realizing the operation of the internal structure of the valve.

[0034] 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.
