Description

Technical Field

[0001] This utility model relates to the field of float valve technology, and in particular to an intelligent regulating float valve. Background Technology

[0002] A circular float valve for a float valve tower, disclosed in Chinese Patent No. CN220531628U, includes a float valve body. Three positioning legs are provided on the outer peripheral wall of the float valve body. A valve leg mechanism is provided on the float valve body to facilitate its assembly and disassembly. The valve leg mechanism includes a connecting seat, a valve leg body, a sliding groove, a slider, a locking block, and a telescopic spring. Connecting seats are fixedly installed around the bottom of the float valve body, located between the three positioning legs. With this circular float valve for a float valve tower, the valve leg mechanism allows for easy disassembly and assembly. By pushing the slider upwards to compress the telescopic spring, the slider moves upwards, disengaging the locking block from the valve leg body and releasing its fixed state. The valve leg body is then flipped inwards, tilting it towards the folded valve leg body, allowing for easy removal of the float valve body. This makes assembly and disassembly of the float valve body very convenient, achieving the goal of facilitating float valve assembly and disassembly.

[0003] The above-mentioned documents and existing technologies have the following problems: In the current float valves, when gas passes through the flat valve plate, the gas-liquid contact is relatively simple, which makes it difficult to flexibly adjust according to the gas flow rate. The gas-liquid distribution is uneven, making it difficult to fully realize the exchange of substances. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent regulating float valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent regulating float valve, comprising a float valve body, a support seat provided inside the float valve body, a first valve plate provided on the surface of the float valve body, a through hole provided on the inner wall surface of the first valve plate, a first rotating rod provided on the inner wall surface of the float valve body, a second valve plate provided at the end of the first rotating rod, and a second rotating rod provided on the side of the second valve plate.

[0006] Preferably, the surface of the float valve body is provided with valve legs, and the valve legs are arranged in a circumferential array on the surface of the float valve body.

[0007] Preferably, the inner wall surface of the float valve body is provided with a support rod, and the support seat is fixedly connected to the float valve body through two support rods.

[0008] Preferably, the end of the second rotating rod is rotatably connected to the side of the support base, and the second valve plate is rotatably connected to the float valve body and the support base through the first rotating rod and the second rotating rod, respectively.

[0009] Preferably, the surface of the second valve plate is provided with a guide groove, and the guide groove is arc-shaped.

[0010] Preferably, the first valve plate is fan-shaped and is arranged axially symmetrically on the surface of the float valve body.

[0011] Preferably, the second valve plate is fan-shaped and is arranged axially symmetrically on the surface of the float valve body.

[0012] Beneficial effects

[0013] In this invention, a first valve plate, a second valve plate, a through hole, a first rotating rod, and a second rotating rod are employed. The wave-shaped first valve plate, through its unique wave structure, allows gas to flow along the crests and troughs as it passes through the first valve plate, and then out through the through hole. The gas velocity is relatively low at the troughs and relatively high at the crests, forming a complex flow path between the crests and troughs. This flow pattern increases the contact area and contact time between the gas and liquid, thereby significantly improving mass transfer efficiency and ensuring thorough mixing of the gas and liquid. Simultaneously, the rotating second valve plate can flexibly adjust its opening degree according to changes in gas flow rate using the first and second rotating rods, precisely controlling the gas flow rate. When the gas flow rate is low, the rotation angle of the second valve plate is small, and the gas passage is small. When the gas flow rate increases, the rotation angle of the second valve plate increases, and the gas passage also increases accordingly, better adapting to the dynamic changes in gas-liquid load within the tower. The two work together to make the gas-liquid contact no longer singular, significantly improving mass transfer efficiency and separation effect. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4 A smart regulating float valve includes a float valve body 1, which serves as the main structure of the entire float valve, providing an installation foundation and support for other components. Valve legs 2 are arranged in a circumferential array on the surface of the float valve body 1. The valve legs 2 ensure that the float valve body 1 is firmly placed in the corresponding position on the tray, bearing its own weight and various forces generated under the action of gas and liquid, preventing displacement or shaking during operation, and ensuring normal operation. Support rods 3 are provided on the inner wall surface of the float valve body 1, providing a stable support structure. A support base 4 is fixedly connected to the float valve body 1 via two support rods 3. The internal structure is equipped with a support base 4, which provides support and rotational support for the second valve plate 6. The surface of the float valve body 1 is provided with a first valve plate 5, and the inner wall surface of the first valve plate 5 is provided with a through hole 7. The first valve plate 5 is fan-shaped and is axially symmetrically arranged on the surface of the float valve body 1. The first valve plate 5 has a wave-shaped structure. When gas passes through, the gas flows along the crests and troughs. The gas velocity is relatively low at the troughs and relatively high at the crests. This special flow path increases the contact area and contact time between the gas and the liquid. The through hole 7 on the inner wall surface provides an outlet channel for the gas, which helps the gas and liquid to mix fully, thereby significantly improving the mass transfer efficiency.

[0024] The inner wall surface of the float valve body 1 is provided with a first rotating rod 9, the end of the first rotating rod 9 is provided with a second valve plate 6, and the side of the second valve plate 6 is provided with a second rotating rod 10. The end of the second rotating rod 10 is rotatably connected to the side of the support base 4. The second valve plate 6 is rotatably connected to the float valve body 1 and the support base 4 through the first rotating rod 9 and the second rotating rod 10 respectively. The second valve plate 6 is fan-shaped and is axially symmetrically arranged on the surface of the float valve body 1. The sides of two adjacent second valve plates 6 are set as mutually cooperating inclined surfaces, and the edges are rounded, with sufficient rotation angle and space, so that the first rotating rod 9 and the second rotating rod 10 can transmit power. The second valve plate 6 is designed to rotate around the first rotating rod 9 and the second rotating rod 10 according to changes in gas flow rate, thereby adjusting the size of the gas channel and achieving precise control of gas flow rate. The surface of the second valve plate 6 is provided with a guide groove 8, which is arc-shaped. The main function of the guide groove 8 is to guide the flow direction of the gas. When the gas passes through the second valve plate 6, the guide groove 8 can make the gas spray out along a specific arc-shaped path, making the gas distribution on the tray more uniform. This avoids the problem of excessively high or low gas velocity caused by concentrated gas spray in local areas, improves the uniformity of gas-liquid mixing, and thus improves mass transfer efficiency and separation effect.

[0025] When the gas comes into contact with the wavy first valve plate 5, it flows along its crests and troughs, and simultaneously flows out through the through-holes 7 on the inner wall surface of the first valve plate 5. During this process, the gas velocity is lower at the troughs and higher at the crests, forming a complex flow path. This increases the contact area and time with the liquid, achieving thorough mixing of the gas and liquid and improving mass transfer efficiency. Meanwhile, when the gas flow rate is low, the second valve plate 6 rotates at a smaller angle due to the transmission between the first rotating rod 9 and the second rotating rod 10, thus narrowing the gas passage. Conversely, when the gas flow rate increases, the first rotating rod 9 and the second rotating rod 10... Rod 10 drives the second valve plate 6 to rotate at an increased angle, and the gas passage increases accordingly. During the process of the second valve plate 6 rotating to adjust the gas passage, the arc-shaped guide groove 8 on its surface guides the gas to spray out along a specific arc-shaped path, making the gas distribution on the tray more uniform, avoiding local gas velocity anomalies, and further improving the uniformity of gas-liquid mixing and mass transfer efficiency. The entire floating valve is fixed on the tray by the valve legs 2, maintaining stability during operation. All components work together, and the airflow can also flow out through the gap between the valve legs 2, achieving good adaptation to the dynamic changes of gas-liquid load in the tower, and efficiently completing the gas-liquid mass transfer and separation tasks. Specific Implementation Example 2:

[0027] A smart regulating float valve, based on the basic structure in Specific Embodiment 1, is further disclosed as follows: Guide grooves 8 can also be formed on the top surface of the second valve plate 6. When gas passes through the second valve plate 6, it can flow out from the guide grooves 8 on both sides. This design makes the gas flow path more diversified. The guide grooves 8 on the top surface and the guide grooves 8 on the bottom surface guide the gas into the liquid in a coordinated manner, which helps to more accurately control the gas ejection direction and distribution state, further enhancing the mixing effect between gas and liquid. This results in more uniform gas-liquid contact on the tray, significantly improving gas-liquid mass transfer efficiency and separation effect.

[0028] In summary:

[0029] 1. The system employs a first valve plate 5, a second valve plate 6, a through hole 7, a first rotating rod 9, and a second rotating rod 10. The wave-shaped first valve plate 5, through its unique wave structure, allows gas to flow along the crests and troughs as it passes through the first valve plate 5, and then out through the through hole 7. The gas velocity is relatively low at the troughs and relatively high at the crests, forming a complex flow path between the crests and troughs. This flow pattern increases the contact area and contact time between the gas and liquid, thereby significantly improving mass transfer efficiency and ensuring thorough mixing of the gas and liquid. Simultaneously, the rotating second valve plate 6 can flexibly adjust its opening degree according to changes in gas flow rate using the first rotating rod 9 and the second rotating rod 10, precisely controlling the gas flow rate. When the gas flow rate is low, the rotation angle of the second valve plate 6 is small, and the gas passage is small. When the gas flow rate increases, the rotation angle of the second valve plate 6 increases, and the gas passage also increases accordingly, better adapting to the dynamic changes in gas-liquid load within the tower. The two work together to make the gas-liquid contact no longer singular, significantly improving mass transfer efficiency and separation effect.
