Description

Technical Field

[0001] This utility model relates to the technical field of rotary gas distribution valves, specifically a rotary gas distribution valve with gas sensing function. Background Technology

[0002] A rotary gas distribution valve is a device that achieves uniform gas distribution by rotating the valve. It has many advantages during use, such as stable and uniform airflow distribution, continuous air intake and exhaust, and small pipeline pressure fluctuations, which greatly improves purification efficiency and thermal efficiency.

[0003] As disclosed in CN221824611U, a rotary gas distribution valve with easy protection belongs to the field of distribution valves. It includes a valve seat and a motor mounted on the valve seat. The valve seat has a protective cover, and plug-in plates are fixedly connected to all four sides of the top of the protective cover. The inner surface of the plug-in plates has snap-fit ​​grooves. All four sides of the top of the valve seat have plug-in holes. A groove is formed on one side of the valve seat near each plug-in hole, and a spring is installed inside the groove. One end of the spring is fixedly connected to a snap-fit ​​block, and a lever is fixedly connected to the top of the snap-fit ​​block. Through the arrangement of the plug-in plates, snap-fit ​​grooves, plug-in holes, springs, snap-fit ​​blocks, and levers, when the rotary gas distribution valve needs maintenance, simply moving the lever removes the snap-fit ​​block from the snap-fit ​​groove, allowing the protective cover to be removed. This facilitates maintenance of the rotary gas distribution valve and improves maintenance efficiency.

[0004] However, existing technologies have problems such as cumbersome connection and disassembly operations between pipes and the outside world, poor tightness, inconvenient maintenance, poor overall sealing effect at the connection, and lack of gas sensing function. For example, the comparative patents listed above have these problems.

[0005] To address this issue, we propose a rotary gas distribution valve with gas sensing capabilities. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1-7 The present invention provides the following technical solution.

[0032] Example 1: To address the lack of gas sensing functionality in existing technologies, this example provides a rotary gas distribution valve with gas sensing capabilities. The valve comprises a rotary gas distribution valve body 1, an interface pipe 2, an external gas pipe 3, a gas flow monitor 7, a mounting base 8, a mounting rod 9, a mounting column 10, and a spring 11. The interface pipe 2 is fixedly connected to both ends of the rotary gas distribution valve body 1. An external gas pipe 3 is located on the outer side of the interface pipe 2. A T-shaped mounting rod 9 is fixedly connected to both ends of the mounting base 8. A mounting column 10 for limiting the position is telescopically connected to the outer side of the mounting rod 9. The mounting column 10 is inserted into the inner sidewalls of both ends of the interface pipe 2. A spring 11 is located between the mounting column 10 and the mounting rod 9. A gas flow monitor 7 is fixedly mounted on the left end of the mounting base 8, and the gas flow monitor 7 is placed within the interface pipe 2. Figure 2 , Figure 4 and Figure 5 As shown, firstly, by pressing the mounting post 10, the mounting post 10 slides between itself and the mounting rod 9, compressing the spring 11 and causing it to elastically deform. Then, the gas flow monitor 7 is placed in the interface tube 2, with the mounting post 10 aligned with the fixing holes on the inner walls of both ends of the interface tube 2. Next, the mounting post 10 is released, at which point the spring 11 returns to its elastic deformation, pushing the mounting post 10 to slide between itself and the mounting rod 9, allowing the mounting post 10 to be inserted into the fixing holes at the corresponding positions on the inner walls of the interface tube 2. Thus, the gas flow monitor 7 can be fixedly installed in the interface tube 2. The gas flow monitor 7 can sense and detect the gas flow rate. Moreover, the rotary gas distribution valve body 1 in this solution is completely consistent with the existing rotary gas distribution valve, belonging to existing conventional and mature technology, which is well known to those skilled in the art and will not be described in detail.

[0033] Example 2: To address the problem of poor overall sealing at the connection points in existing technologies, this example provides the following technical solution: a rotary gas distribution valve with gas sensing function, comprising a connecting sleeve 4, a first sealing ring 5, and a second sealing ring 6. The connecting sleeve 4 is fitted onto the end of the external gas pipe 3 near the rotary gas distribution valve body 1. The first sealing ring 5 is fitted between the connecting sleeve 4 and the external gas pipe 3, and is positioned on the outside of the external gas pipe 3. The connecting sleeve 4 is fitted onto the outer surface of the interface pipe 2, and the second sealing ring 6 is fitted onto the outside of the interface pipe 2, fitting snugly between the connecting sleeve 4 and the interface pipe 2. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting sleeve 4 is fitted onto the outer surface of the interface tube 2, and a second sealing ring 6 is fitted between the connecting sleeve 4 and the interface tube 2. A first sealing ring 5 is fitted between the inner side of the connecting sleeve 4 and the external air tube 3, and the external air tube 3 and the interface tube 2 are fitted together. The first sealing ring 5 and the second sealing ring 6 greatly improve the sealing effect at the connection and prevent leakage.

[0034] Example 3: To address the problems of cumbersome connection and disassembly operations, poor fastening, and inconvenient maintenance in existing technologies, this example provides a rotary gas distribution valve with gas sensing function. The valve is equipped with a positioning mechanism 12. Positioning mechanisms 12 are located on both the front and rear sides of the connecting sleeve 4. These positioning mechanisms 12 cause the connecting sleeve 4 and the interface pipe 2 to form a disassembly structure. The positioning mechanism 12 consists of a positioning column 13, a positioning rod 14, a movable plate 15, a support block 16, and... The system comprises a fixed cap 17, positioning pins 13 fixedly connected to the front and rear sides of the connecting sleeve 4, and a positioning rod 14 fixedly connected to the distal end of the positioning pin 13. The positioning pin 13 is inserted into the middle of the movable plate 15, and the positioning rod 14 is engaged with the movable plate 15. The movable plate 15 and the support block 16 form a front-to-back sliding structure, and the support block 16 is fixedly connected to the outer side of the rotary gas distribution valve body 1. The outer surface of the positioning rod 14 is threaded with a fixed cap 17 for locking and limiting, and the fixed cap 17 is engaged with the movable plate 15. Figure 6 and Figure 7As shown, after the connecting sleeve 4 is fitted onto the outside of the interface tube 2, the movable plate 15 is pulled, and the movable plate 15 slides with the support block 16. At this time, the positioning pin 13 is inserted into the movable plate 15, and the positioning rod 14 is engaged with the movable plate 15. Then, by rotating the fixing cap 17 threaded to the outer surface of the positioning rod 14, the fixing cap 17 is engaged with the movable plate 15, which facilitates the positioning pin 13 and the movable plate 15 to be limited, thereby fixing the connecting sleeve 4 and the interface tube 2, which is convenient for installation. Moreover, the connection can be disassembled and maintained by reversing the above operation.

[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.
