[0022] 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.
[0023] Please see Figure 1-3 A sanitary gas integrated one-way valve block includes a valve body 1, four air inlet connectors 2, one gas outlet connector 3, one wastewater outlet connector 4, and four sets of one-way valve core mechanisms 5. Four first locking interfaces 6 are provided on the upper end face of the valve body 1, each connecting to one of the four air inlet connectors 2. A first sealing ring 9 is provided between the air inlet connector 2 and the first locking interface 6. A second locking interface 7 is provided on the lower end face of the valve body 1, connecting to the gas outlet connector 3. A second sealing ring 10 is provided between the gas outlet connector 3 and the second locking interface 7. A third locking interface 8 is provided on the right end face of the valve body 1, connecting to the wastewater outlet connector 4. A third sealing ring 11 is provided between the wastewater outlet connector 4 and the third locking interface 8. The wastewater outlet connector 4 is used to discharge waste gas and wastewater. The four sets of one-way valve core mechanisms 5 are located inside the valve body 1 and are connected to the four first locking interfaces 6. All gas inlet connectors of the valve body 1 are for sanitary gas input.
[0024] Specifically, the one-way valve core mechanism 5 includes an inner tube 51 and an outer tube 52; the inner tube 51 is connected to the top surface of the inner cavity of the valve housing 1 and docks with the first locking interface 6, the outer tube 52 is connected to the bottom surface of the inner cavity of the valve housing 1, and the lower end of the inner tube 51 is located inside the outer tube 52; a valve port is provided on the inner wall of the inner tube 51, and a valve core 53 is provided at the valve port. The valve core 53 is slidably connected to the guide rod 54, and the lower end of the guide rod 54 is inserted into the bottom surface of the inner cavity of the valve housing 1; a spring 55 is sleeved on the guide rod 54, and the upper end of the spring 55 is connected to the valve core 53; a leakage notch 56 is opened at the lower end of the inner tube 51.
[0025] Specifically, after the air inlet connector 2 is connected to the air source, the airflow will push the valve core 53 downward, causing the spring 55 to contract. The airflow enters the inner cavity of the valve body 1 through the air leakage notch 56 at the lower end of the inner tube 51, and then outputs from the air outlet connector 3. After the air source is closed, the spring 55 resets and pushes the valve core 53 upward to close the valve port.
[0026] This sanitary gas integrated one-way valve block, by setting multiple air inlet connectors 2 and one air outlet connector 3 on the valve body 1, can connect multiple air sources to the gas circuit block. After the gas circuit block is integrated, the air is input.
