[0002] In chemical enterprises, pneumatic valves are crucial control devices, widely used in piping systems. Due to the complexity of the chemical environment and the diversity of pneumatic valves, incompatibility issues frequently arise during maintenance, often involving different specifications and models of valves with mismatched interfaces. This leads to low maintenance efficiency and can even impact production safety. Existing conversion couplings are mostly of a single specification, unable to accommodate multiple interface types, and are complex to operate and inconvenient to carry. Therefore, there is an urgent need for a pneumatic valve air supply pipeline conversion coupling device to improve maintenance efficiency and safety. Utility Model Content

[0003] The purpose of this utility model is to provide a pneumatic valve air source pipeline conversion joint device to solve the problems mentioned in the background art.

[0004] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0005] A pneumatic valve air source pipeline conversion joint device includes a main pipeline, a connecting valve, and a connector.

[0006] Furthermore, the connecting valve includes eight sets of connecting pipes, which are axially installed symmetrically around the axis of the main pipeline on the outside of the main pipeline. This symmetrical distribution design allows the gas in the main pipeline to be evenly distributed to each connecting pipe, ensuring stable gas pressure in each connecting pipe. A ball valve is installed at the free end of each connecting pipe, which can flexibly control the connection between the connecting pipe and the external pipeline, facilitating operation under different working conditions. For example, when connecting or replacing external pipelines, the ball valve can be closed to prevent gas leakage. The connector includes eight sets of connecting discs, which are respectively installed at the inlet of the ball valve. Each connecting disc has a sleeve installed at the center of its side, and the inner diameter of the sleeve gradually decreases from top to bottom. This variable diameter design can adapt to external pipelines of different sizes, improving the versatility of the adapter.

[0007] Furthermore, the connecting pipe is connected to the main pipeline to ensure that the gas in the main pipeline can flow smoothly into the connecting pipe; the outlet of the ball valve is connected to the connecting pipe so that the gas in the connecting pipe can flow out through the ball valve; the sleeve is connected to the inlet of the ball valve to ensure that after the external pipeline is connected to the sleeve, the gas can smoothly enter the ball valve, and then enter the connecting pipe and the main pipeline to form a complete gas passage.

[0008] Furthermore, a threaded pipe is installed at the center of the other side of the connecting plate. The threaded pipe is engaged with the inlet thread of the ball valve. This connection method is not only securely installed, but also facilitates disassembly and replacement of the connector, thus improving the convenience of maintenance.

[0009] Furthermore, a sealing ring is installed on the outside of the threaded pipe, and the sealing ring is used to seal the gap between the threaded pipe and the ball valve inlet, effectively preventing gas leakage, ensuring the airtightness of the entire pipeline system, and avoiding energy waste and safety hazards caused by gas leakage.

[0010] Furthermore, the side of the connecting plate is equipped with an anti-slip ring, which allows the operator to hold the connecting plate more easily when installing or removing the connector, increasing friction, preventing hand slippage, and improving the safety and convenience of operation.

[0011] Furthermore, the connecting disc and the threaded tube are both provided with a first through hole, and the sleeve is provided with a second through hole and a tapered hole. The tapered hole is used to connect the first through hole and the second through hole. This structural design optimizes the gas flow path, allowing the gas to flow more smoothly inside the connector, reducing gas resistance and improving gas transmission efficiency.

[0012] Furthermore, the diameter of the first through hole is smaller than the diameter of the second through hole, and the diameter of the second through hole is the inner diameter of the sleeve. The smaller first through hole can limit the flow and stabilize the pressure of the gas to a certain extent, ensuring that the gas pressure entering the ball valve is stable, while the larger second through hole facilitates the connection of external pipelines, ensuring that the gas can smoothly enter the connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the pneumatic valve air source pipeline conversion connector device can be adapted to various pneumatic valve interfaces through eight sets of connectors of different specifications, which greatly improves the adaptability during maintenance; the ball valve design facilitates the control of gas flow and is simple and convenient to operate; the sealing ring ensures the airtightness of the system and improves safety; the anti-slip ring facilitates operation and reduces the difficulty of operation; the optimized gas flow structure improves gas transmission efficiency and ensures the stable operation of the entire pneumatic valve system.

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.

[0021] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a pneumatic valve air source pipeline conversion joint device, including a main pipeline 100, a connecting valve 200, and a connector 300.

[0022] As an embodiment of the present invention, the connecting valve 200 further includes eight sets of connecting pipes 2002. These eight sets of connecting pipes 2002 are axially symmetrically installed on the outside of the main pipeline 100 with the axis of the main pipeline 100 as the axis. This symmetrical distribution design allows the gas in the main pipeline 100 to be evenly distributed to each connecting pipe 2002, ensuring stable gas pressure in each connecting pipe 2002. A ball valve 2001 is installed at the free end of each connecting pipe 2002. The ball valve 2001 can flexibly control the connection between the connecting pipe 2002 and the external pipeline, facilitating operation under different working conditions. For example, when connecting or replacing an external pipeline, the ball valve can be closed to prevent gas leakage. The connector 300 includes eight sets of connecting discs 3001, which are respectively installed at the inlet of the ball valve 2001. Each connecting disc 3001 has a sleeve 3002 installed at the center of its side, and the inner diameter of the sleeve 3002 gradually decreases from top to bottom. This variable diameter design can adapt to external pipes of different sizes and improve the versatility of the adapter. One row of sleeves 3002 is connected to the external gas input pipe, and the other row of sleeves 3002 is connected to the external gas output pipe. The connection method between the sleeves 3002 and the external pipe is the existing snap-fit ​​method.

[0023] As an embodiment of the present invention, the connecting pipe 2002 is further connected to the main pipe 100 to ensure that the gas in the main pipe 100 can flow smoothly into the connecting pipe 2002; the outlet of the ball valve 2001 is connected to the connecting pipe 2002 so that the gas in the connecting pipe 2002 can be controlled to flow out through the ball valve 2001; the sleeve 3002 is connected to the inlet of the ball valve 2001 to ensure that after the external pipeline is connected to the sleeve 3002, the gas can smoothly enter the ball valve 2001, and then enter the connecting pipe 2002 and the main pipe 100 to form a complete gas passage.

[0024] As an embodiment of the present invention, a threaded pipe 3006 is further installed at the center of the other side of the connecting plate 3001. The threaded pipe 3006 and the inlet thread of the ball valve 2001 are engaged. This connection method is not only firmly installed, but also facilitates disassembly and replacement of the connector 300, thus improving the convenience of maintenance.

[0025] As an embodiment of the present invention, a sealing ring 3007 is further installed on the outside of the threaded pipe 3006, and the sealing ring 3007 is used to seal the gap between the threaded pipe 3006 and the inlet of the ball valve 2001, effectively preventing gas leakage, ensuring the airtightness of the entire pipeline system, and avoiding energy waste and safety hazards caused by gas leakage.

[0026] As an embodiment of the present invention, the side of the connecting plate 3001 is further provided with an anti-slip ring, which allows the operator to hold the connecting plate 3001 more conveniently when installing or removing the connector 300, increasing friction, preventing hand slippage, and improving the safety and convenience of operation.

[0027] As an embodiment of the present invention, the connecting disc 3001 and the threaded tube 3006 are further provided with a first through hole 3004 that is connected to each other, and the sleeve 3002 is provided with a second through hole 3003 and a tapered hole 3005. The tapered hole 3005 is used to connect the first through hole 3004 and the second through hole 3003. This structural design optimizes the gas flow path, so that the gas can flow more smoothly inside the connector 300, reduce gas resistance, and improve gas transmission efficiency.

[0028] As an embodiment of the present invention, the diameter of the first through hole 3004 is smaller than the diameter of the second through hole 3003, and the diameter of the second through hole 3003 is the inner diameter of the sleeve 3002. The smaller first through hole 3004 can limit the flow and stabilize the pressure of the gas to a certain extent, ensuring that the gas pressure entering the ball valve 2001 is stable, while the larger second through hole 3003 facilitates the connection of external pipelines, ensuring that the gas can smoothly enter the interior of the connector 300.

[0029] Specifically, the working principle of this pneumatic valve air source pipeline conversion joint device is as follows: The external air inlet pipe, based on its own diameter, selects a sleeve with a matching inner diameter from a row of sleeves 3002 for connection using a snap-fit ​​method. The external air outlet pipe is connected to a sleeve of the corresponding size in another row of sleeves 3002 in the same manner. A second through hole 3003 is provided inside the sleeve 3002, with a diameter matching the inner diameter of the sleeve, facilitating the connection of the external air inlet pipe. Gas enters the sleeve 3002 through this hole, and the gas flows through the tapered hole 3005 to the first through hole 3004, which connects the connecting plate 3001 and the threaded pipe 3006. The diameter of the first through hole 3004 is smaller than that of the second through hole 3003, which can limit the flow and stabilize the pressure of the gas, ensuring stable gas pressure entering the ball valve 2001. The gas reaches the ball valve 2001 after passing through the first through hole 3004. Operators can control the flow of gas by operating ball valve 2001 according to actual needs. When ball valve 2001 is opened, gas flows into main pipeline 100 from ball valve outlet and finally flows out from external gas outlet pipeline.
