Description

Technical Field

[0001] The utility model relates to the technical field of float valves, in particular to a wear-resistant multifunctional chemical tower float valve. Background Art

[0002] Float valves float on the tower plate, adjusting their opening degree as the gas flow rate changes. Float valves come in many styles, including round valves and angle valves. Round valves are primarily used in China. The most commonly used is the F1 type, for which a national standard (JB1118) has been issued. This standard stipulates that the valve body can be made of carbon steel, stainless steel, or acid-resistant steel. Light valves are 1.5mm thick and weigh approximately 25g, while heavy valves are 2mm thick and weigh approximately 33g.

[0003] The existing chemical tower float valve is prone to friction between the valve leg and the valve hole. When used for too long, the float valve is prone to serious wear and tear, resulting in scrapping. It is also inconvenient to quickly replace the float valve and has a single function. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a wear-resistant multifunctional chemical tower float valve.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wear-resistant multifunctional chemical tower float valve, including a valve cover, a connecting ring is provided at the bottom of the valve cover, a movable groove is provided inside the connecting ring, a compression spring is provided inside the movable groove, a fixed block is provided at the end of the compression spring, a connecting block is provided on the side of the fixed block, a movable block is provided on the surface of the connecting block, a sliding groove is provided on the surface of the connecting ring, a valve leg is provided inside the movable groove, a rubber pad is provided at the bottom of the connecting ring, a limit block is provided at the bottom of the valve leg, and a buffer pad is provided on the surface of the limit block.

[0006] Preferably, five tongue holes are opened on the surface of the valve cover, and the opening directions of the five tongue holes are the same.

[0007] Preferably, three valve legs are arranged in a circular array, and air holes are opened on the surface of the valve legs.

[0008] Preferably, a clamping hole is provided on the surface of the valve leg, and the shape and position of the clamping hole are adapted to the fixing block.

[0009] Preferably, three movable grooves are arranged in a circular array, and the movable grooves are connected to the sliding grooves through-through.

[0010] Preferably, the fixed block is adapted to the movable slot, and the movable block passes through the sliding slot and is movably connected.

[0011] Preferably, the shape of the buffer pad corresponds to that of the limit block, and the surface of the valve leg is provided with a wear-resistant layer.

[0012] Beneficial effects

[0013] In the utility model, a compression spring, a fixed block, a movable block and a sliding groove are adopted. The movable block is slid toward the center in the sliding groove, so that the compression spring is compressed, thereby driving the fixed block to move in the movable groove. The valve leg is inserted into the movable groove, and the movable block is released. Under the reaction force of the compression spring, the fixed block is driven to move toward the clamping hole, thereby fixing the valve leg. It is convenient for personnel to quickly disassemble and assemble the float valve, and the functions are diversified.

[0014] In the utility model, rubber pads and buffer pads are used. When the float valve is in motion, the protection and buffering of the rubber pads and the buffer pads, as well as the wear-resistant layer of paint applied on the surface of the valve leg, improve the wear resistance between the valve leg and the valve hole, thereby increasing the service life of the float valve.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0022] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment one:

[0024] Reference Figure 1-4 A wear-resistant multifunctional chemical tower float valve includes a valve cover 1. The surface of the valve cover 1 is provided with five tongue holes 3, and the opening direction of the five tongue holes 3 is the same. The valve legs 4 are arranged in a circular array with three, and the surface of the valve legs 4 is provided with air holes 5. The air flow moves upward through the tongue holes 3 and the air holes 5, so that the gas and liquid flow evenly on the tower plate. The bottom of the valve cover 1 is provided with a connecting ring 2, and the interior of the connecting ring 2 is provided with a movable groove 11. The interior of the movable groove 11 is provided with a compression spring 12, which controls the fixed block 14 to return to its original position through the compression spring 12. The end of the compression spring 12 is provided with a fixing block 14. The surface of the valve leg 4 is provided with a clamping hole, and the shape and position of the clamping hole are adapted to the fixing block 14. The fixed block 14 is inserted into the card hole to fix the valve leg 4. A connecting block 13 is provided on the side of the fixed block 14. A movable block 9 is provided on the surface of the connecting block 13. A sliding groove 8 is provided on the surface of the connecting ring 2. The movable block 9 passes through the sliding groove 8 and is movably connected. The valve leg 4 is provided inside the movable groove 11. A rubber pad 10 is provided at the bottom of the connecting ring 2. The buffer pad 7 is used to prevent the connecting ring 2 from severe wear. A limit block 6 is provided at the bottom of the valve leg 4. A buffer pad 7 is provided on the surface of the limit block 6. The shape of the buffer pad 7 corresponds to the limit block 6. The buffer pad 7 is used to prevent the limit block 6 from wearing the pedal. The surface of the valve leg 4 is provided with a wear-resistant layer. The wear resistance of the valve leg 4 is improved by setting the wear-resistant layer.

[0025] Slide the movable block 9 toward the center in the sliding groove 8 to compress the compression spring 12, thereby driving the fixed block 14 to move in the movable groove 11, insert the valve leg 4 into the movable groove 11, release the movable block 9, and under the reaction force of the compression spring 12, drive the fixed block 14 to move toward the card hole, thereby fixing the valve leg 4, making it convenient for personnel to quickly disassemble and assemble the float valve. When the float valve is in motion, due to the protective buffering of the rubber pad 10 and the buffer pad 7, and the wear-resistant layer of paint applied on the surface of the valve leg 4, the wear resistance between the valve leg 4 and the valve hole is improved, thereby increasing the service life of the float valve. Specific embodiment two:

[0027] Reference Figure 1-4 On the premise of meeting the above structure, a limit rod can be set on the surface of the valve leg 4 to match it with the valve hole to prevent the float valve from deviating during the up and down movement and aggravating the wear.

[0028] In summary:
