Description

Technical Field

[0001] This utility model relates to the field of aeration pipe technology, specifically a plug-and-play air valve device that can be installed on an aeration pipe. Background Technology

[0002] An aeration pipe is a conduit in an aeration system that transports compressed air. Aerators (such as microporous aeration discs or aeration heads) are installed at the end of the pipe or at specific locations. Their function is to break the air into tiny bubbles, increasing the contact area with the wastewater and thus improving oxygen transfer efficiency.

[0003] Its end is usually equipped with several valve ports, and each valve port is equipped with a hose for air conduction. The hose is usually installed on the valve port through a threaded interface or a quick-connect interface. The threaded interface has the advantage of tight connection and is not easy to fall off, but its installation and disassembly process is relatively cumbersome. The quick-connect interface has the advantage of quick installation and disassembly, but since most of them are one-piece snap-fit ​​connections, there is a risk of falling off under the impact of airflow. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a plug-and-play air valve device that can be installed on an aeration pipe, offering the advantages of quick assembly and disassembly, tight installation, and resistance to detachment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a main pipeline and a valve assembly installed on the main pipeline, wherein at least two branch pipelines are fixed on the outer periphery of the main pipeline, and the valve assembly is detachably installed on the branch pipelines; The valve assembly includes a pipeline valve and a quick-connect sleeve, wherein the pipeline valve is fixedly installed on the branch pipeline, and the quick-connect sleeve is movably connected to the pipeline valve. One end of the pipeline valve has at least two quick-connect grooves, and one end of the quick-connect sleeve is fixed with at least two main clamping plates. The main clamping plates cooperate with the inner wall of the quick-connect grooves to form a snap-fit ​​connection.

[0006] Preferably, the quick-connect sleeve is further provided with an auxiliary clamping plate, a gear turntable and a fixing plate. There are at least two auxiliary clamping plates and gear turntables, which mesh with each other. The auxiliary clamping plate slides inside the quick-connect sleeve, and the gear turntable rotates inside the quick-connect sleeve.

[0007] Preferably, the auxiliary card plate is located outside the main card plate, and the combined thickness of the two is the same as the thickness of the quick-connect groove. The quick-connect groove is provided with a number of snap-fit ​​protrusions, and the bottom of the main card plate is also provided with a number of protrusions. The two work together to form a quick-connect buckle.

[0008] Preferably, a sealing block is installed on the outer periphery of the auxiliary card plate, the outer end face of the sealing block is inclined, and a rack groove is opened on the side end face of the auxiliary card plate near the gear turntable, and a rack is provided in the rack groove.

[0009] Preferably, the gear turntable is movably mounted inside the quick-connect sleeve via a rotating shaft, the gear turntable meshes with the rack inside the rack groove, a push plate is fixed on the gear turntable, and a torsion spring for resetting is provided on the rotating shaft of the gear turntable.

[0010] Preferably, a top rod is fixed to one end of the fixing plate, the top rod extends toward one side of the pipeline valve, and a sealing ring is also provided on the end face of the fixing plate near the pipeline valve.

[0011] Preferably, the pipeline valve is provided with a butterfly valve and a secondary valve. The butterfly valve is controlled to rotate by a handle installed on the butterfly valve from the outside. The secondary valve is provided with a barrier ball.

[0012] Preferably, the secondary valve has a spherical cavity inside, and the diameter of the center of the blocking ball is larger than the diameter of the outermost inlet and outlet of the cavity, but smaller than the diameter of the cavity itself.

[0013] Compared with the prior art, this utility model provides a plug-and-play air valve device that can be installed on an aeration pipe, and has the following advantages: 1. This plug-and-play gas valve device, installed on the aeration pipe, provides a double-layer sealing effect for the aeration pipeline when the butterfly valve is open, thanks to the barrier ball inside the secondary valve. This prevents a large amount of gas leakage from the pipeline. It can also be used with quick-connect sleeves to achieve a plug-and-play effect.

[0014] 2. This plug-and-play air valve device, installed on the aeration pipe, uses an auxiliary locking plate. When the airflow reaches the gear turntable, it pushes the gear turntable, causing the auxiliary locking plate to slide into the quick-connect groove, forming a wedge that completely fills the entire quick-connect groove. This completely locks the main locking plate, preventing deformation and locking the quick-connect sleeve so it cannot be pulled out. This prevents the quick-connect sleeve from falling off and causing gas leakage due to excessive airflow impact during use. Attached Figure Description

[0017] 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.

[0018] like Figure 1-8 As shown, the system includes a main pipe 10 and a valve assembly installed on the main pipe 10. At least two branch pipes 11 are fixed to the outer periphery of the main pipe 10. The valve assembly is detachably installed on the branch pipes 11. The valve assembly includes a pipe valve 20 and a quick-connect sleeve 30. The pipe valve 20 is fixedly installed on the branch pipe 11 and serves as the main valve of the aeration pipe. The quick-connect sleeve 30 is used for quick disconnection of external pipes and as a secondary valve, i.e., for the butterfly valve 21. By controlling the position of the butterfly valve 21, the flow of gas in the aeration pipe can be controlled. The quick-connect sleeve 30 is movably connected to the pipe valve 20. At least two quick-connect grooves 23 are provided at one end of the pipe valve 20. At least two main clamping plates 301 are fixed at one end of the quick-connect sleeve 30. The main clamping plates 301 have a certain elasticity. When they enter the quick-connect grooves 23, they will undergo slight deformation to achieve a snap-fit ​​engagement. The main clamping plates 301 and the inner wall of the quick-connect grooves 23 cooperate to form a snap-fit ​​connection, realizing the quick installation and disassembly of the external pipes.

[0019] The pipeline valve 20 is equipped with a butterfly valve 21 and a secondary valve 22. The butterfly valve 21 is controlled to rotate by a handle 211 installed on the butterfly valve 21. The secondary valve 22 has a movable barrier ball 221 inside. The secondary valve 22 has a spherical cavity. The diameter of the barrier ball 221 is larger than the diameter of the outermost inlet and outlet of the cavity, but smaller than the diameter of the cavity. Through the setting of the barrier ball 221 inside the secondary valve 22, when the butterfly valve 21 is open, it can not only provide a double-layer sealing effect for the aeration pipeline to prevent gas leakage in the pipeline, but also achieve a plug-and-play effect when used with the quick-connect sleeve 30.

[0020] The quick-connect sleeve 30 is also provided with an auxiliary clamping plate 31, a gear turntable 32 and a fixing plate 33. There are at least two auxiliary clamping plates 31 and gear turntables 32, which mesh with each other. The auxiliary clamping plate 31 slides inside the quick-connect sleeve 30, and the gear turntable 32 rotates inside the quick-connect sleeve 30. The other end of the quick-connect sleeve 30 is fixed with a hose 34. The internal shape of the quick-connect sleeve 30 matches one end face of the pipeline valve 20, and the two fit together perfectly.

[0021] The auxiliary locking plate 31 is located outside the main locking plate 301. The combined thickness of the two is the same as the thickness of the inner groove of the quick-connect groove 23. Several locking protrusions 231 are provided inside the quick-connect groove 23, and several protrusions are also provided at the bottom of the main locking plate 301. The two work together to form a quick-connect buckle. That is, after the quick-connect sleeve 30 is directly inserted, the locking protrusions 231 and the protrusions work together to form a preliminary engagement. At this time, the airflow switch is not turned on. Continue to push the quick-connect sleeve 30 until the top rod 331 on the fixing plate 33 pushes open the blocking ball 221, which opens the airflow channel. When the airflow flows to the gear turntable 32, it will push the gear turntable 32 to drive the auxiliary locking plate 31 to slide into the quick-connect groove 23, forming a wedge, completely filling the entire quick-connect groove 23, so that the main locking plate 301 is completely locked, and the quick-connect sleeve 30 is locked and cannot be pulled out. This avoids the problem of gas leakage caused by the quick-connect sleeve 30 falling off due to excessive airflow impact during use.

[0022] A sealing block 311 is installed on the outer periphery of the auxiliary plate 31. The outer end face of the sealing block 311 is set with an inclination. A rack groove 312 is opened on the end face of the auxiliary plate 31 near the gear turntable 32. A rack is set in the rack groove 312. The gear turntable 32 is movably installed in the quick-connect sleeve 30 through a rotating shaft. The gear turntable 32 meshes with the rack inside the rack groove 312. A push plate 321 is also fixed on the gear turntable 32. A torsion spring for resetting is set on the rotating shaft of the gear turntable 32. One end of the torsion spring is fixed on the gear turntable 32 and the other end is fixed on the inner wall of the quick-connect sleeve 30. The sealing block 311 can completely fill the gap between the auxiliary plate 31 and the quick-connect sleeve 30 during the sliding process of the auxiliary plate 31, so as to completely seal it and prevent gas leakage. The push plate 321 is set so that it can impact the push plate 321 during the gas flow, providing power to the auxiliary plate 31. That is, when the airflow is flowing, the auxiliary plate 31 can slide.

[0023] A push rod 331 is fixed to one end of the fixing plate 33. The push rod 331 extends toward one side of the pipeline valve 20. A sealing ring is also provided on the end face of the fixing plate 33 near the pipeline valve 20. The top of the push rod 331 extends beyond the position of the main clamping plate 301. That is, when the main clamping plate 301 is partially engaged, the push rod 331 can push open the blocking ball 221. When the main clamping plate 301 is fully engaged, the blocking ball 221 can be fully pushed open.

[0024] Working principle: In use, the quick-connect sleeve 30 is directly inserted into the pipe valve 20. At this time, the main clamping plate 301 corresponds to the quick-connect groove 23 and is initially locked in the quick-connect groove 23 by the protrusion. Continue to push the quick-connect sleeve 30 in. At this time, the push rod 331 will gradually push open the blocking ball 221. Initially, the opening gap is small and the airflow is small, which cannot push the push plate 321 to rotate. Therefore, the main clamping plate 301 can continue to be locked into the quick-connect groove 23 until the blocking ball 221 is opened larger and the airflow can push the push plate 321 to rotate. Through the gear turntable 32, the auxiliary clamping plate 31 is driven to slide, so that the auxiliary clamping plate 31 also enters the quick-connect groove 23 and locks the main clamping plate 301. At this time, the main clamping plate 301 cannot be deformed, that is, it cannot be inserted or pulled out. At this time, the installation is completed. That is, the whole process only requires the insertion action. Moreover, the airflow channel is opened during the insertion process, realizing plug and play.

[0025] To ensure safety, the entire quick-connect sleeve 30 is locked during airflow and cannot be pulled out. If it needs to be pulled out, the butterfly valve 21 can be closed to stop the airflow. The gear turntable 32 will reset under the action of the torsion spring, and the auxiliary clamping plate 31 will also be pulled out simultaneously. At this time, the main clamping plate 301 can deform, and the quick-connect sleeve 30 can be pulled out directly. Then, the butterfly valve 21 can be opened, and the airflow will blow the blocking ball 221 to block the auxiliary valve 22, thus achieving a seal.

[0026] In summary, this plug-and-play gas valve device installed on the aeration pipe, through the setting of the blocking ball 221 inside the secondary valve 22, not only provides a double-layer sealing effect for the aeration pipeline when the butterfly valve 21 is open, preventing gas leakage in the pipeline, but also achieves a plug-and-play effect in conjunction with the quick-connect sleeve 30. Through the setting of the auxiliary clamping plate 31, when the airflow flows to the gear turntable 32, it will push the gear turntable 32 to drive the auxiliary clamping plate 31 to slide into the quick-connect groove 23, forming a wedge, completely filling the entire quick-connect groove 23, so that the main clamping plate 301 is completely locked and cannot be deformed, and the quick-connect sleeve 30 is locked and cannot be pulled out. This avoids the problem of gas leakage caused by the quick-connect sleeve 30 falling off due to excessive airflow impact force during use.
