Description

Technical Field

[0001] This utility model relates to the field of floating valve tray technology, and in particular to an adjustable guide floating valve tray. Background Technology

[0002] According to Chinese Patent Publication No. CN211885509U, a floating valve tray for chemical applications includes a first tray and two second trays, as well as "L"-shaped mounting plates fixed to the bottom of the two second trays by bolts. The first tray has a rectangular structure, and the two second trays and the first tray form a circular structure. The bottom of the mounting plate is movably inserted into a slot, which is formed on a base plate. A movable plate is movably disposed in the slot. This invention, by setting a first tray and two second trays, with the two second trays located below the first tray, and the first tray being a rectangular tray, allows for the direct removal of the two second trays from below the first tray when a circular structure is required during installation. The second trays are then moved and spliced ​​to both sides of the first tray to form a circular structure. This design offers greater flexibility, wider applicability, a simpler structure, and greater practicality.

[0003] The above-mentioned documents and existing technologies have the following technical problems: the float valves in the existing float valve trays are pushed up and down entirely by airflow, which makes it inconvenient for personnel to adjust the opening according to the actual situation, and also causes the airflow to rush around and cause serious entrainment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable guide floating valve tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable guide floating valve tray, comprising a tray body, a valve port on the surface of the tray body, a valve cover on the surface of the valve port, a valve leg on the bottom surface of the valve cover, a fixing seat on the surface of the tray body, a fixing plate on the surface of the fixing seat, an adjusting component on the surface of the fixing plate, a spring on the bottom surface of the valve cover, a connecting rod inside the valve leg, and a connecting seat at the end of the connecting rod.

[0006] Preferably, the adjusting assembly includes a screw, a limiting ring, a limiting rod, and a rotating handle. The screw is threadedly connected to the surface of the limiting ring, the limiting ring is provided with a limiting rod on its surface, and the screw is provided with a rotating handle at its end.

[0007] Preferably, the valve port has a guide groove on its surface, and the valve leg has a guide rod on its side.

[0008] Preferably, the surface of the valve leg is provided with a venting groove, and the surface of the valve cover is provided with a dispersion groove.

[0009] Preferably, the spring is wound around the surface of the screw, and the screw is connected through the surface of the valve cover.

[0010] Preferably, a limiting groove is provided on the side of the fixed base, and the limiting rod is slidably connected to the surface of the limiting groove.

[0011] Preferably, the connecting seat is rotatably connected to the end of the screw, and the end of the spring is connected to the surface of the connecting seat.

[0012] Beneficial effects In this invention, an adjusting component and a spring are used to make the maximum opening height of the float valve no longer dependent on the natural push of the airflow, but can be manually adjusted according to the working conditions. The limiting ring connected to the screw can move precisely up and down when the rotating handle drives the screw to rotate, thereby changing the limit height that the float valve can reach when it is open, and realizing fine control of the maximum opening amount of the float valve. At the same time, the lower end of the screw is rotatably connected to the connecting seat, and the spring is sleeved on the outside of the screw and connected to the connecting seat, so that the float valve can maintain controlled buffer when it rises under the action of airflow, and can reliably fall back when the air velocity decreases. This not only makes the opening degree of the float valve adjustable under different operating conditions and the response more linear, but also effectively avoids the problems of skewing, jamming and unstable jumping caused by airflow impact in traditional float valves, making the airflow distribution more uniform, reducing liquid entrainment, and significantly improving the mass transfer efficiency and operational stability of the tray.

[0015] 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.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-4 An adjustable guide-type floating valve tray includes a tray body 1. The surface of the tray body 1 has a valve port 2, the surface of the valve port 2 has a valve cover 3, the bottom surface of the valve cover 3 has a valve leg 4, the surface of the valve port 2 has a guide groove 5, the side of the valve leg 4 has a guide rod 6, the surface of the valve leg 4 has a venting groove 7, and the surface of the valve cover 3 has a dispersion groove 12. The tray body 1 serves as a load-bearing structure, used to fix the valve port 2, the fixing seat 8, and all other functional components, and to bear the liquid and gas flow loads. Located inside the tower, it provides an installation base for all other structures. Gas enters below the valve cover 3 through the valve port 2, pushing the floating valve to open. The valve port 2 is the core part of the gas rising channel. The valve cover 3 rises and falls under the gas pressure, regulating the flow of gas through the valve port 2. The flow rate is increased, and the gas is evenly dispersed through the dispersion groove 12 to improve gas-liquid contact. The valve leg 4 supports the valve cover 3 and moves up and down in a limited direction in the guide groove 5 to prevent the float valve from tilting or tipping. The guide groove 5 provides a linear sliding guide for the guide rod 6 on the valve leg 4, so that the float valve only moves up and down in the vertical direction to prevent jamming and tilting. The guide rod 6, as a lateral guide element of the valve leg 4, cooperates with the guide groove 5 to form a stable guide structure, so that the float valve operates smoothly and reliably. When the float valve is closed or partially open, the venting groove 7 allows some airflow to pass through the side wall of the valve leg 4, improving the venting capacity of the float valve under low load and preventing it from shaking when completely closed. When the float valve is open, the dispersion groove 12 cuts and evenly distributes the airflow, increases the gas-liquid contact area, and improves mass transfer efficiency.

[0018] The surface of the tray body 1 is provided with a fixing seat 8, and the surface of the fixing seat 8 is provided with a fixing plate 9. The fixing seat 8 fixes the adjusting assembly 10 and provides a mounting base for the screw 1001 to ensure stable positioning of the adjusting mechanism. The fixing plate 9 is used to support the screw 1001, so that the installation position of the adjusting assembly 10 is stable and the screw 1001 is prevented from shifting. The surface of the fixing plate 9 is provided with the adjusting assembly 10, which includes a screw 1001, a limiting ring 1002, a limiting rod 1003, and a rotating handle 1004. A limit ring 1002 is threaded onto the surface of the rod 1001. A limit rod 1003 is provided on the surface of the limit ring 1002. A rotating handle 1004 is provided at the end of the screw 1001. A limit groove 11 is provided on the side of the fixed seat 8. The limit rod 1003 is slidably connected to the surface of the limit groove 11. The screw 1001 is the core adjusting shaft. By rotating, the limit ring 1002 can be moved up and down, changing the maximum opening height of the float valve. It also serves as the guide shaft of the spring 15 and is rotatably connected to the connecting seat 14. The limiting ring 1002 serves as a key limiting component for adjusting the maximum lift of the float valve. When the float valve is pushed up by airflow, the limiting ring 1002 restricts its maximum upward movement, thereby controlling the opening. The limiting rod 1003 is inserted into the limiting groove 11 to form a linear guide, preventing the limiting ring 1002 and screw 1001 assembly from rotating or shifting during adjustment, ensuring stable and reliable limiting action. The rotating handle 1004 is used to manually rotate the screw 1001, facilitating quick external adjustment of the float valve's maximum opening by the operator. After adjustment, the operator fixes the rotating handle 1004 to the fixing plate 9 using pins to prevent rotation during actual use. A spring 15 is provided on the bottom surface of the valve cover 3, and the spring 15 is wound around the surface of the screw 1001. The screw 1001 is connected to the surface of the valve cover 3. A connecting rod 13 is provided inside the valve leg 4. The end of the connecting rod 13 is provided with a connecting seat 14, which is rotatably connected to the end of the screw 1001. The end of the spring 15 is connected to the surface of the connecting seat 14. The connecting rod 13 connects the valve leg 4 to the connecting seat 14, so that the float valve can synchronously drive the connecting seat 14 to move when it rises and falls. The connecting seat 14 is rotatably connected to the bottom end of the screw 1001 to avoid the rotation of the screw 1001 during the adjustment process from affecting the spring 15. At the same time, as the lower support point of the spring 15, the spring 15 is only sleeved on the screw 1001 and has no fixed contact. The spring 15 provides a downward pressure reset force for the float valve, so that the float valve can fall quickly when the air velocity is low or there is no airflow, keeping the valve port 2 sealed. At the same time, it provides a buffering effect to prevent the float valve from jumping violently and impacting the limit ring 1002 due to high air velocity, and to avoid excessive rise, thereby improving the stability of the operation. Specific Implementation Example 2: An adjustable guide float valve tray, based on the basic structure in Specific Embodiment 1, further discloses the following: The operator first rotates the screw 1001 by rotating the handle 1004 according to the tower's operating load and target throughput, causing the limiting ring 1002 to move up and down along the thread, thereby preset the maximum opening height of the float valve. The linear guidance of the limiting rod 1003 within the limiting groove 11 ensures a smooth and accurate adjustment process. After adjustment, the handle 1004 is locked by a pin or fastener, keeping the limiting ring 1002 in the set position. After the device enters the operating state, gas rises from the valve port 2 and pushes the valve cover 3, causing the valve leg 4 to rise. The arc-shaped venting groove 7... This allows gas to pass smoothly evenly under low load, while the dispersion groove 12 further evenly distributes the gas, improving gas-liquid contact efficiency. During the rise of the float valve, the guide rod 6 and guide groove 5 maintain vertical guidance to avoid skewing and jamming. When the float valve rises to the adjustment height, the connecting rod 13 and connecting seat 14 below it drive the spring 15 to be compressed. The spring 15 provides buffering and return force, so that the float valve maintains a smooth rise and fall when the gas speed fluctuates, and automatically and reliably falls back when the gas speed decreases, realizing the timely closure of the valve port 2. Through the combined action of the manually adjusted limit ring 1002 and the automatically responding spring 15, the float valve can achieve a controllable, stable, and highly efficient working process under different working conditions.

[0020] In summary: 1. By employing the adjusting component 10 and spring 15, the maximum opening height of the float valve no longer depends on the natural push of the airflow, but can be manually adjusted according to the operating conditions. The limiting ring 1002 threaded on the screw 1001 can move precisely up and down when the rotating handle 1004 drives the screw 1001 to rotate, thereby changing the limit height that the float valve can reach when it is open, and realizing fine control of the maximum opening amount of the float valve. At the same time, the lower end of the screw 1001 is rotatably connected to the connecting seat 14, and the spring 15 is sleeved on the outside of the screw 1001 and connected to the connecting seat 14, so that the float valve can maintain controlled buffering when it rises under the action of airflow, and can reliably fall back when the air velocity decreases. This not only makes the opening degree of the float valve adjustable under different operating conditions and the response more linear, but also effectively avoids the problems of skewing, jamming and unstable jumping caused by airflow impact in traditional float valves, making the airflow distribution more uniform, reducing liquid entrainment, and significantly improving the mass transfer efficiency and operating stability of the tray body 1.
