Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of top float valves, specifically relating to a conical top float valve. Background Technology
[0002] In chemical, petroleum, and other industrial sectors, conical top float valves are key components of gas-liquid mass transfer equipment, widely used in mass and heat transfer processes within towers. Their performance directly affects the operating efficiency and stability of the equipment.
[0003] Existing top-floating valves are generally flat-top structures, which have certain limitations. Firstly, due to the limited area of the valve, mass and heat transfer efficiencies are not high. Secondly, heat accumulation occurs due to contact with the medium and the valve's own mass and heat transfer processes; however, traditional top-floating valves lack effective cooling structures, leading to excessively high temperatures, which in turn affects the valve's mass transfer efficiency and service life. Furthermore, because top-floating valves operate in complex media environments for extended periods, their corrosion resistance needs improvement. The inner surface of the metal valve is easily corroded by the medium, affecting not only the normal operation of the equipment but also potentially posing safety hazards. Additionally, after prolonged use, the valve's edges tend to adhere to the tray. Therefore, it is necessary to improve the structure and optimize the function of existing conical top-floating valves to meet the growing demands for high efficiency, stability, and safety in industrial production.

[0012] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0013] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0015] A conical top float valve, such as Figure 1 As shown, the system includes a top plate 1, with inclined surrounding plates 2 around its perimeter. The upper end of each inclined surrounding plate 2 is fixedly connected to the top plate 1, and both sides of each inclined surrounding plate 2 are fixedly connected to adjacent inclined surrounding plates 2. The lower end of each inclined surrounding plate 2 has a wavy edge 3, and a support rod 4 is fixedly connected to the lower end of the connection between the inclined surrounding plate 2 and the adjacent inclined surrounding plate 2. A conical top float valve is installed on a tray 15, which has several air holes 17 connected to tube sections 16. The conical top float valve corresponds one-to-one with each tube section 16, and the conical top float valve covers the corresponding tube section 16. When the gas pressure inside the tower is too high, the conical top float valve can move up and down to release pressure. The wavy edge 3 prevents the conical top float valve from sticking to the tube section 16 on the tray 15. The top plate 1 and the inclined surrounding plates 2 increase the gas-liquid contact area of the top float valve, improving heat and mass transfer efficiency.
[0016] Furthermore, the top plate 1 and the inclined enclosure 2 are both equipped with serpentine cooling water channels 12. All cooling water channels 12 are sequentially connected to form a water path. One end of each water path is connected to an inlet pipe via an inlet hose, which in turn is connected to a water tank via a water pump. The other end of the water path is connected to an outlet pipe via an outlet hose, which in turn is connected to the water tank. The conical top float valve maintains a constant temperature through circulating water, preventing excessive heat buildup, ensuring stable mass transfer efficiency, and extending its service life.
[0017] Furthermore, a lifting plate 5 is fixedly connected to the support rod 4. The lifting plate 5 has a movable hole 6, into which a guide rod 7 is movably inserted. The lower end of the guide rod 7 is fixedly connected to a mounting plate 8, which has several mounting holes. The guide rod 7 is connected to the tray 15 by bolts passing through the mounting holes on the mounting plate 8, thus forming a fixed structure. When the gas pressure inside the tower is too high, the conical top float valve can float up and down relative to the tray 15 to relieve pressure.
[0018] Furthermore, the upper end of the guide rod 7 is threadedly connected to a limiting plate 10, and a spring 11 is fitted onto the guide rod 7. Adjusting the height of the limiting plate 10 can adjust the elastic force of the spring 11, thereby adjusting the vertical lifting range.
[0019] Furthermore, both the top plate 1 and the inclined surrounding plate 2 are made of stainless steel, and the top plate 1 and the inclined surrounding plate 2 are welded together, as are adjacent inclined surrounding plates 2. Stainless steel is corrosion-resistant, has high structural strength, and a long service life.
[0020] Furthermore, plastic films are affixed to the inner surfaces of the top plate 1 and the inclined enclosure 2, respectively. Removing the plastic film allows for quick cleaning, and a new plastic film can be applied after maintenance.
[0021] It is worth mentioning that the technical features such as water pumps involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.
[0022] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
