Description

Technical Field

[0001] This utility model relates to the field of float valve technology, specifically an environmentally friendly rubber float valve. Background Technology

[0002] In numerous industrial fields such as chemical engineering, environmental protection, and petroleum, float valves are widely used as an important component for controlling fluid flow. Traditional float valves primarily control fluid flow and volume by the up-and-down movement of a float.

[0003] Currently, the rubber ball of the float valve is a key control component. However, during long-term use, the rubber ball is prone to wear and aging due to fluid scouring, corrosion, and frequent opening and closing actions. This can affect the normal working performance of the float valve, leading to a decrease in fluid control accuracy and even safety hazards such as leakage.

[0004] Furthermore, the existing float valve structure involves a complex disassembly process when the rubber ball needs to be replaced. It usually requires disassembling multiple components of the entire float valve, which consumes a lot of time and manpower. Therefore, the entire float valve is usually replaced directly, which increases the burden of waste disposal. Each stage of waste float valve disposal will cause soil, groundwater, and air pollution, exacerbating climate change. At the same time, the production of new float valves is energy-intensive and generates a lot of pollution. Frequent replacements increase the environmental pressure of production and increase the emission of pollutants such as carbon footprint. Utility Model Content

[0010] The first mounting sleeve is movably mounted on the first connecting pipe, and the first rubber ball is fixedly mounted on the first mounting sleeve. The first mounting sleeve is used to provide a stable mounting structure for the first rubber ball, and also facilitates the replacement and maintenance of the first rubber ball.

[0011] Preferably, a first mounting rod is fixedly mounted on the first mounting sleeve, one end of a first spring is fixedly mounted on the first mounting rod, and the other end of the first spring is fixedly connected to the first rubber ball.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figures 1-4 This utility model provides the following two technical solutions:

[0028] First implementation method: An environmentally friendly rubber float valve, comprising:

[0029] The valve body 1 has three valve leg assemblies 2 that are centrally symmetrically distributed at its bottom. The valve body 1 is used to contain and guide the flow of fluid, and the valve leg assemblies 2 are used to support the valve body 1 and place it stably in the installation position.

[0030] The first connecting pipe 3 is fixedly installed at the bottom center of the valve body 1. The first connecting pipe 3 is used to connect the valve body 1 with the external fluid, so that the fluid can flow smoothly into or out of the valve body 1.

[0031] The first rubber ball 4 is movably installed inside the first connecting pipe 3. The first rubber ball 4 is used to control the flow of fluid according to the pressure and level changes of the fluid.

[0032] The first mounting sleeve 5 is made of rubber. The first mounting sleeve 5 is elastically fitted onto the first connecting pipe 3. The first mounting rod 6 is fixedly installed on the first mounting sleeve 5. One end of the first spring 7 is fixedly installed on the first mounting rod 6. The other end of the first spring 7 is fixedly connected to the first rubber ball 4. The first mounting sleeve 5 is used to provide a stable mounting structure for the first rubber ball 4, and also facilitates the replacement and maintenance of the first rubber ball 4.

[0033] Three centrally symmetrically distributed second connecting pipes 8 are evenly installed at the bottom of the valve body 1. The inner diameter of the second connecting pipe 8 is smaller than that of the first connecting pipe 3. A second mounting sleeve 9 is movably installed on the second connecting pipe 8. The material of the second mounting sleeve 9 is rubber. The second mounting sleeve 9 is elastically fitted onto the second connecting pipe 8. A second mounting rod 10 is fixedly installed inside the second mounting sleeve 9. One end of a second spring 11 is fixedly installed on the second mounting rod 10. A second rubber ball 12 is fixedly installed on the other end of the second spring 11. The second rubber ball 12 is movably installed inside the second connecting pipe 8.

[0034] As the fluid pressure or level rises, the force acting on the first rubber ball 4 gradually increases. When this force exceeds the elastic force of the first spring 7, the first rubber ball 4 will overcome the spring's elastic force and move upward, releasing the first connecting pipe 3, allowing the fluid to flow smoothly into or out of the valve body 1 through the first connecting pipe 3, thereby achieving control over the fluid flow. The second connecting pipe 8 and the second rubber ball 12 play an auxiliary role in controlling the fluid. When the fluid pressure or level changes slightly, the first rubber ball 4 may still block the first connecting pipe 3. If the fluid pressure or level changes to the extent that the second rubber ball 12 moves, the second rubber ball 12 will overcome the elastic force of the second spring 11 under pressure and move upward, releasing the second connecting pipe 8. Some fluid can flow through the second connecting pipe 8. When the fluid pressure or level changes further, causing the first rubber ball 4 to also release the first connecting pipe 3, the fluid can flow through both the first connecting pipe 3 and the second connecting pipe 8 simultaneously, achieving a larger flow rate.

[0035] In this embodiment, the inner diameters of the first connecting pipe 3 and the second connecting pipe 8 are different, and the first rubber ball 4 and the second rubber ball 12 are connected by springs, enabling the float valve to achieve multi-level and precise fluid on / off control according to different fluid pressure and liquid level changes. Based on actual working conditions, by adjusting parameters such as the spring elastic coefficient, the pressure and liquid level thresholds for different rubber balls releasing the connecting pipe can be precisely set to meet different flow and pressure regulation requirements, thus improving the operating efficiency and stability of the fluid conveying system. The first mounting sleeve 5 and the second mounting sleeve 9 are elastically fitted onto the connecting pipe, facilitating disassembly and installation. This design makes the replacement and maintenance of the first rubber ball 4 and the second rubber ball 12 more convenient and quick, reducing equipment maintenance costs and downtime.

[0036] The second embodiment differs from the first embodiment in that: each of the three valve leg assemblies 2 has a threaded rod 13 threadedly installed at its lower end, a swivel ring 14 is fixedly installed at the lower end of the threaded rod 13, and a support sleeve 15 is installed at the bottom of the threaded rod 13; the support sleeve 15 is made of rubber and is fitted onto the bottom of the threaded rod 13.

[0037] By rotating the rotating ring 14, since the threaded rod 13 and the valve leg assembly 2 are threadedly engaged, according to the principle of thread transmission, rotating the rotating ring 14 will cause the threaded rod 13 to move up and down along the thread axis. In this way, the height of each valve leg assembly 2 can be adjusted individually. In the actual installation process, the installation surface may not be completely flat. By rotating the rotating ring 14 at the lower end of each valve leg assembly 2, the support height of the three valve leg assemblies 2 can be adjusted to adapt to uneven ground. This ensures that the valve body 1 is in a horizontal state, ensuring the normal operation of the float valve and avoiding the valve body 1 tilting due to uneven installation surface, which would affect the flow of fluid and the normal operation of components such as the rubber ball. Different installation scenarios may have different requirements for the installation height and levelness of the float valve. The adjustable valve leg assembly 2 allows the float valve to be installed in various scenarios, such as on the workshop floor, pipe supports, and other different locations, which can be installed stably, improving the versatility and applicability of the float valve. The elasticity of the support sleeve 15 plays a role in buffering and shock absorption, further ensuring the stability of the installation.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] In use, place the float valve in the predetermined installation position and observe the levelness of the valve body 1. Adjust the extension length of the threaded rod 13 by rotating the swivel ring 14 at the lower end of each valve leg assembly 2 until the valve body 1 is in a horizontal state, ensuring that the float valve can be stably placed in the installation position. When the fluid pressure or liquid level changes slightly, it may first reach the point where the second rubber ball 12 moves. At this time, the second rubber ball 12 will move upward under the pressure, overcoming the elastic force of the second spring 11, and releasing the second connecting pipe 8. Some fluid can flow into or out of the valve body 1 through the second connecting pipe 8. When the fluid pressure or liquid level changes further, and the force acting on the first rubber ball 4 exceeds the elastic force of the first spring 7, the first rubber ball 4 will move upward over the elastic force of the spring, releasing the first connecting pipe 3. At this time, the fluid can flow through the first connecting pipe 3 and the second connecting pipe 8 simultaneously, achieving a larger flow rate.
