Description

Technical Field

[0001] This utility model relates to the field of circular float valve technology, and in particular to a circular float valve for use in chemical equipment. Background Technology

[0002] According to Chinese Patent Publication No. CN 220531628 U, a circular float valve for a float valve tower includes a float valve body with three positioning legs on its outer peripheral wall. The float valve body is equipped with a valve leg mechanism for easy 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 can then be flipped inwards and tilted towards the folded valve leg body side to remove it. This makes assembly and disassembly of the float valve body very convenient, achieving the goal of facilitating float valve assembly and disassembly.

[0003] Existing technical problems: Most of the current float valves have right-angled valve legs, which means that after packaging, the sharp edges of the valve legs will puncture the packaging, exposing the float valve, causing damage and waste, and increasing production costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circular float valve for chemical equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circular float valve for chemical equipment, comprising a float valve tray, wherein three float valve frames are evenly arranged on the surface of the float valve tray, and movable feet are movably connected to the bottom ends of the three float valve frames. A fixed frame is provided on the surface of the movable feet, and movable rods are movably connected to both ends of the fixed frame. A connecting plate is movably connected to the top end of the movable rods. A connecting rod is movably connected to one side surface of the connecting plate and the inner surface of the fixed frame, and a fixed plate is movably connected to the other side surface of the connecting plate.

[0006] Preferably, the surface of the floating valve tower plate is uniformly provided with three grooves, and the top of the floating valve frame corresponds to the inner surface of the groove.

[0007] Preferably, the surface of the fixed frame is movably connected to one end of the movable rod by a first bolt, and the surface of the connecting plate is movably connected to one end of the connecting rod by a second bolt.

[0008] Preferably, the bottom of the floating valve tray is provided with a valve plate, and the surface of the valve plate is provided with perforations, which correspond to the floating valve tray.

[0009] Preferably, a support ring is fixedly connected to the bottom surface of the valve plate, and a limit ring is movably connected inside the support ring. Three T-shaped fixing feet are evenly provided on the inner surface of the limit ring.

[0010] Preferably, a positioning block is fixedly connected to the surface of the fixed frame, and a positioning groove is formed on the top surface of the positioning block.

[0011] Preferably, the bottom end of the T-shaped fixing foot is movably connected to the inside of the positioning groove, and the T-shaped fixing foot and the positioning groove correspond to each other.

[0012] Beneficial effects

[0013] In this invention, a movable rod is used. The first bolt moves the movable rod and the connecting plate, while the second bolt moves the connecting rod and the fixed plate. The movable foot and the float valve frame are folded, thus ensuring that the edge of the valve leg will not puncture the packaging after the float valve is packaged, and the float valve will not be exposed, reducing damage and waste of the float valve, and lowering production costs.

[0014] In this invention, a T-shaped fixing foot is used. Through the T-shaped fixing foot and the positioning groove, the contact area between the T-shaped fixing foot and the floating valve tray is effectively increased, thereby improving its compressive strength and minimizing the risk of the floating valve tray being pulled off by gas or liquid with excessive flow velocity due to uneven stress, thus improving its durability.

[0023] 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.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-6 A circular float valve for chemical equipment includes a float valve tray 2. Three float valve frames 7 are evenly arranged on the surface of the float valve tray 2. Movable feet 3 are movably connected to the bottom ends of the three float valve frames 7. Fixed frames 8 are provided on the surface of the movable feet 3. Movable rods 11 are movably connected to both ends of the fixed frames 8. A connecting plate 12 is movably connected to the top end of the movable rods 11. A connecting rod 13 is movably connected to one side surface of the connecting plate 12 and the inner surface of the fixed frame 8. A fixed plate 14 is movably connected to the other side surface of the connecting plate 12.

[0027] The surface of the floating valve tower plate 2 is evenly provided with three grooves. The top of the floating valve frame 7 corresponds to the inner surface of the groove. The surface of the fixed frame 8 is movably connected to one end of the movable rod 11 with a first bolt 15. The surface of the connecting plate 12 is movably connected to one end of the connecting rod 13 with a second bolt 16. The bottom of the floating valve tower plate 2 is provided with a valve plate 1. The surface of the valve plate 1 is provided with a through hole 17, which corresponds to the floating valve tower plate 2. The bottom surface of the valve plate 1 is fixedly connected with a support ring 4. The inside of the support ring 4 is movably connected with a limit ring 5. The inner surface of the limit ring 5 is evenly provided with three T-shaped fixing feet 6. The surface of the fixed frame 8 is fixedly connected with a positioning block 9. The top surface of the positioning block 9 is provided with a positioning groove 10. The bottom end of the T-shaped fixing foot 6 is movably connected to the inside of the positioning groove 10, and the T-shaped fixing foot 6 corresponds to the positioning groove 10.

[0028] In use, the movable foot 3 is bent and placed inside the perforation 17. Then, the limiting ring 5 is put on the outside of the movable foot 3 as a whole, and the support ring 4 is rotated to make the T-shaped fixed foot 6 enter the positioning groove 10. This ensures that after the float valve is packaged, the edge of the valve leg will not puncture the packaging, and the float valve will not be exposed, reducing damage and waste of the float valve and lowering production costs. Specific Implementation Example 2:

[0030] Reference Figure 1-6 A circular float valve for chemical equipment, based on the basic structure in Specific Embodiment 1, further solves the problem that the first bolt 15 and the second bolt 16 may come into contact with the liquid and rust due to the need to rotate during use, making it impossible to rotate and fold. The first bolt 15 and the second bolt 16 can be made of silicone, which can avoid contact with the liquid and rust, and also reduce the wear generated during rotation.

[0031] In summary:

[0032] 1. The movable rod 11 is used. The first bolt 15 makes the movable rod 11 and the connecting plate 12 move, while the second bolt 16 makes the connecting rod 13 and the fixed plate 14 move. The movable foot 3 and the float valve frame 7 are folded, so that the edge of the valve leg will not puncture the packaging after the float valve is packaged, and the float valve will not be exposed, reducing the damage and waste of the float valve and reducing production costs.

[0033] 2. The T-shaped fixing foot 6 is adopted. Through the T-shaped fixing foot 6 and the positioning groove 10, the contact area between the T-shaped fixing foot 6 and the floating valve tray 2 is effectively increased, thereby improving its compressive strength and minimizing the risk of uneven stress causing the floating valve tray 2 to be driven off by gas or liquid with excessive flow velocity, thus improving its service durability.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
