Description

Technical Field

[0001] This utility model belongs to the field of sealing valve technology, and in particular relates to a pneumatic rotary sealing valve. Background Technology

[0002] Pneumatic rotary sealing valves are valves with special structures and functions, mainly used in applications requiring the blocking of airflow and meeting airtightness requirements. Also known as shut-off valves or airtight valves, their design allows ventilation systems to be divided into several zones. They play a crucial role, especially in biosafety laboratories, where they are primarily used to block airflow in ventilation ducts and isolate filters and contaminated components to protect personnel and the environment.

[0003] The pneumatic rotary sealing valves currently on the market have the following problems when used:

[0004] 1. In actual use, traditional pneumatic rotary sealing valves are usually connected to the pipeline using only a flange structure. However, after long-term use, the flange structure may loosen, resulting in insufficient sealing.

[0005] 2. Most pneumatic rotary sealing valves are assembled with multiple sets of fasteners on the outside of the device body. If the fasteners become loose, workers need to use fastening tools to fix them. Since there is no structure to store the tools, there is no storage structure during use. Utility Model Content

[0029] like Figure 1-5 As shown, this utility model discloses a pneumatic rotary sealing valve, comprising a valve body 1 and a valve seat 2. The valve body 1 has a valve seat 2 at its bottom, and a fixing ring 3 on the side of the valve seat 2. A sealing groove 4 is formed on the side of the fixing ring 3. A reinforcing plate 6 is provided on the outer side of the fixing ring 3. A sealing ring 5 is provided on one side of the reinforcing plate 6, and a flange seat 12 is provided on the other side of the reinforcing plate 6. Due to the presence of the reinforcing plate 6, it is convenient to splice the sealing ring 5 and the flange seat 12. The sealing ring 5 is embedded in the sealing groove 4. A frame 7 is provided on the outer side of the reinforcing plate 6. A threaded rod 8 passes through the inside of the frame 7, and a nut 9 is connected to the threaded rod 8. By providing a fixing ring 3 and a reinforcing plate 6 on the side of the valve seat 2, and embedding the sealing ring 5 inside the sealing groove 4, and providing fasteners inside the frame 7, a more stable sealing effect can be achieved. The reinforcing plate 6 is removed, and the sealing ring 5 on the side is embedded in the sealing groove 4. Then, the fasteners are removed and the two are fastened together, thus fixing the reinforcing plate 6 and the fixing ring 3 together.

[0030] A limiting plate 20 is provided on the side of the valve body 1. A fastening screw 19 is embedded inside the limiting plate 20. A storage box 13 is provided on the inner side of the limiting plate 20. A threaded groove 18 is opened on the side of the storage box 13. The fastening screw 19 is threaded to the threaded groove 18. A rubber frame 17 is embedded inside the storage box 13. The storage box 13 is connected to the top cover 16 through a rotating shaft. By providing a limiting plate 20 and a fastening screw 19 on the side of the valve body 1, and a storage box 13 on the inner side of the limiting plate 20, and installing a rubber frame 17 inside the storage box 13, the structure of the storage box 13 is removed and aligned with the limiting plate 20. The fastening screw 19 is then tightened to fix the two together. Then, the rubber frame 17 is installed inside the storage box 13, so that tools can be inserted into the storage box 13.

[0031] The valve seat 2 is connected to the side of the connecting plate 10, and the threaded rod 8 passes through the inside of the connecting plate 10. The connecting plate 10 facilitates the passage of the threaded rod 8.

[0032] The frame 7 has a through hole 11 inside, through which a threaded rod 8 passes. There are four sets of threaded rods 8. Because of the through hole 11, it is easy for the threaded rod 8 to pass through the inside of the frame 7.

[0033] The storage box 13 has a positioning groove 15 inside, and the bottom of the rubber frame 17 has a positioning plate 14. The positioning plate 14 is embedded in the positioning groove 15. Because of the positioning groove 15 and the positioning plate 14, it is convenient to install the rubber frame 17 inside the storage box 13.

[0034] The limiting plates 20 are symmetrically distributed, and the side of the limiting plates 20 is connected with reinforcing ribs 21. The installation of reinforcing ribs 21 can improve the connection strength between the limiting plates 20.

[0035] The working principle of this pneumatic rotary sealing valve is as follows: When using this device, the device body first needs to be moved to a suitable position. After moving it to a suitable position, it can be placed on a flat surface. Then, the sealing valve body is connected to the pipeline. In order to improve the sealing performance between the valve seat 2 and the pipeline, a structure to improve the sealing effect is installed. This is achieved by providing a fixing ring 3 and a reinforcing plate 6 on the side of the valve seat 2, and embedding a sealing ring 5 inside the sealing groove 4. Fasteners are provided inside the frame 7. Before using the valve body 1, the reinforcing plate 6 is removed. The side of the reinforcing plate 6 has a sealing ring 5, and the side of the fixing ring 3 has a sealing groove 4. The sealing ring 5 is embedded inside the sealing groove 4. Next, the connecting plate 10 is connected to the outside of the valve seat 2, and the frame 7 is connected to the side of the reinforcing plate 6. A through hole 11 is opened inside the frame 7. Then, the threaded rod 8 is removed and passed through the through hole 11 and the connecting plate 10 respectively. Then, the nut 9 on the outside of the threaded rod 8 is tightened. This fixes the reinforcing plate 6 and the fixing ring 3, making the sealing performance stronger during use. To facilitate the storage of maintenance tools, a limiting plate 20 is provided on the side of the valve body 1. A fastening screw 19 is embedded inside the limiting plate 20, and a storage box 13 is provided inside the limiting plate 20. A rubber frame 17 is installed inside the storage box 13. Before using the equipment, remove the storage box 13, align its side with the limiting plate 20, and then tighten the fastening screw 19 to connect it to the threaded groove 18, thus securing the connection. Next, remove the rubber frame 17, whose bottom has a positioning plate 14. A positioning groove 15 is provided inside the storage box 13, and the positioning plate 14 is embedded inside the positioning groove 15. In this way, the rubber frame 17 structure can be installed inside the storage box 13, so that tools can be stored inside the storage box 13. It has a storage structure when in use. If the sealing valve structure fails later, the staff can take out the repair tools from the storage box 13. After the repair is completed, the tools are placed back inside the storage box 13, and then the top cover 16 is closed. Finally, the sealing valve structure can be used.
