Description

A float valve with strong sealing performance

Technical Field

The utility model belongs to the technical field of floating ball valves, in particular to a floating ball valve with strong sealing performance.

Background Art

The float valve is a type of valve, which is composed of a crank arm and a float. It can be used to automatically control the liquid level of a water tower or pool. It has the characteristics of simple maintenance, flexibility and durability, high liquid level control accuracy, water level is not affected by water pressure, and tight opening and closing without water leakage.

The float valves currently on the market have the following problems when in use:

1. When installing and connecting a traditional float valve, one end of the float valve is usually connected to the pipeline through threads, and the threads are tightened together while squeezing the sealing plug toward the middle to achieve sealing at the connection. However, when the threads between the pipeline and the float valve are loose, the squeezing force of the two on the sealing plug may become smaller, resulting in reduced sealing between the float valve and the pipeline, and poor sealing effect during use;

2. The float of the traditional float valve always floats on the water when in use. When the water level rises and water needs to be injected, the float also rises, which drives the connecting rod connected to the float to rise. The connecting rod is connected to the valve at the other end. As the float rises, the valve will gradually close, the water flow will gradually decrease, and the water injection speed will gradually decrease, resulting in low water injection efficiency during use.

Preferably, the surface of the valve body is fixedly connected to a mounting frame, and bolts are provided inside the mounting frame.

The utility model has the following advantages:

1. This kind of float valve with strong sealing performance has a universal regulating valve on the top of the valve body, and the other end of the universal regulating valve is connected to the valve stem through a rotating shaft seat, and a floating ball body is arranged on the other end of the valve stem. A sealing plug is sleeved on the outside of the valve body, and a double-threaded barrel is sleeved on the outside of the valve body. A sealing gasket is installed inside the double-threaded barrel. When connected with a pipeline, the sealing plug is fitted to the inner wall of the pipeline and embedded inside the pipeline. The double threads inside the double-threaded barrel are respectively threadedly connected with the inner and outer walls of the pipeline, and the double-threaded barrel is tightened. The pipeline and the double-threaded barrel squeeze the sealing gasket. The double sealing of the sealing plug and the sealing gasket can effectively improve the sealing performance of the connection between the pipeline and the valve body. When the thread is loose, the sealing plug is still embedded in the inside of the pipeline and fits with the inner wall of the pipeline, which effectively avoids the situation where the sealing performance of the float valve with the pipeline is reduced when the thread between the pipeline and the float valve is loose, and the sealing effect is better when it is used;

2.

After the water level drops, the float body will drop accordingly until it is adsorbed by the magnet ring to the iron shell. When the water level rises, the initial buoyancy is small. The float body will not rise with the water surface because the iron shell outside is adsorbed by the magnet ring, so the float body will not be closed tightly and the water injection speed will not be reduced. As the water surface gradually rises and covers the float body, the buoyancy of the float body gradually increases until the buoyancy is greater than the adsorption force of the magnet ring. The float body will float up and drive the float valve to close gradually, and the water injection efficiency will be faster during use.

In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a float valve with strong sealing performance of the utility model in conjunction with the accompanying drawings.

As shown in Fig. 1-4, a float valve with strong sealing performance of the utility model comprises a valve body 1 and a float body 8. A universal adjusting rod 6 is installed on the top of the valve body 1. The other end of the universal adjusting rod 6 is connected to the shaft seat 5 by a rotating shaft. The side of the shaft seat 5 is fixedly connected to the valve stem 7. Through the valve stem 7, when the float body 8 is driven to move by the buoyancy of the liquid, the end of the valve stem 7 connected to the float body 8 is also driven, thereby driving the closing and opening of the valve, which is more convenient to use. The other end of the valve stem 7 is provided with a float body 8. The outside of the valve body 1 is sleeved with a sealing plug 2. The outside of the valve body 1 is sleeved with a double-threaded cylinder 3. The double-threaded cylinder 3 is sleeved with a sealing plug 2. A sealing gasket 4 is installed inside. Through the double-threaded barrel 3, when connected to the pipeline, the double-threaded barrel 3 is tightened so that the double threads inside the double-threaded barrel 3 are respectively threadedly connected to the inner and outer wall threads of the pipeline, so that one end of the pipeline is pressed against the sealing gasket 4 inside the double-threaded barrel 3. The double sealing of the sealing plug 2 and the sealing gasket 4 improves the sealing performance of the connection between the pipeline and the valve body 1. When the threads of the double-threaded barrel 3 are loose, the sealing plug 2 is still embedded in the inside of the pipeline and fits with the inner wall of the pipeline, which effectively avoids the situation where the sealing performance of the float valve with the pipeline is reduced when the threads between the pipeline and the float valve are loosened, and the sealing effect is better.

The outside of the float body 8 is fixedly connected to the iron shell 10, the outer wall of the iron shell 10 fits the magnet ring 11, the outside of the valve body 1 is sleeved with the first arc plate 13, the side of the first arc plate 13 is fixedly connected to the support rod 19, and the other end of the support rod 19 is provided with a magnet ring 11. The iron shell 10 on the surface of the float body 8 is adsorbed by the provided magnet ring 11. When the water level begins to rise, the buoyancy of the float body 8 is initially small. The float body 8 is adsorbed by the magnet ring 11 because the iron shell 10 on the outside is adsorbed by the magnet ring 11, so that the float body 8 will not rise with the water surface, so that the valve will not become smaller, and the water injection speed will not decrease. As the water surface gradually rises and submerges the float body 8, the buoyancy of the float body 8 will gradually increase, and the float body 8 will break away from the suction of the magnet ring 11 to drive the float valve to gradually close, and the water injection efficiency will be faster during use.

One end of the valve stem 7 is threadedly connected to the mounting seat 9, and the surface of the float body 8 is fixedly connected to the mounting seat 9. The provided mounting seat 9 makes it more convenient to connect the float body 8 to the valve stem 7 and to install it.

The side of the support rod 19 is fixedly connected to the fixing seat 12, and the interior of the fixing seat 12 is connected to the magnet ring 11 by bolts. Through the fixing seat 12 provided, the fixing seat 12 and the magnet ring 11 are fixed by bolts, so that the magnet ring 11 is fixed to one end of the support rod 19, which is more stable when used.

The bottom rotating shaft of the first arc plate 13 is connected to the second arc plate 14, the side of the first arc plate 13 is fixedly connected to the first fixing block 15, the side of the second arc plate 14 is fixedly connected to the second fixing block 17, the inner thread of the second fixing block 17 is connected to the butterfly bolt 16, through the butterfly bolt 16 provided, the butterfly bolt 16 is tightened, and the butterfly bolt 16 is threadedly connected to the second fixing block 17, thereby pressing the first fixing block 15 downward, so that the first fixing block 15 and the second fixing block 17 are pressed toward the middle, driving the first arc clamping plate and the second arc clamping plate to squeeze the valve body 1 toward the middle, thereby fixing the first arc plate 13 and the second arc plate 14 to the outside of the valve body 1, which is more convenient to use.

The surface of the valve body 1 is fixedly connected to a mounting bracket 18, and bolts are arranged inside the mounting bracket 18. Through the mounting bracket 18, after the valve body 1 and the pipeline are installed, they can be connected with other components through the mounting bracket 18, so that the installed valve body 1 is more stable and has better stability during use.

The working principle of the highly airtight float valve: when the highly airtight float valve is used, a universal adjusting rod 6 is installed on the top of the valve body 1, and the other end of the universal adjusting rod 6 is connected to the shaft seat 5 with a rotating shaft, and the side of the shaft seat 5 is fixedly connected to the valve stem 7. Through the provided valve stem 7, when the float body 8 is driven to move by the buoyancy of the liquid, the end of the valve stem 7 connected to the float body 8 is also driven, thereby driving the closing and opening of the valve. The other end of the valve stem 7 is provided with a float body 8, the outside of the valve body 1 is sleeved with a sealing plug 2, the outside of the valve body 1 is sleeved with a double-threaded tube 3, and a sealing gasket 4 is installed inside the double-threaded tube 3. When connected to the pipeline, the sealing plug 2 is fitted to the inner wall of the pipeline and embedded into the inside of the pipeline, and then the double-threaded tube is tightened. The double threads of the double-threaded cylinder 3 are respectively connected with the inner and outer wall threads of the pipeline until one end of the pipeline is pressed against the sealing gasket 4 inside the double-threaded cylinder 3. The sealing performance of the connection between the pipeline and the valve body 1 is improved through the double sealing of the sealing plug 2 and the sealing gasket 4. When the threads of the double-threaded cylinder 3 are loose, the sealing plug 2 is still embedded in the inside of the pipeline and fits with the inner wall of the pipeline, so that there can still be a good seal between the pipeline and the valve body 1, which effectively avoids the situation where the sealing performance of the float valve with the pipeline is reduced when the threads between the pipeline and the float valve are loosened. The sealing effect is better when using it. The outside of the float body 8 is fixedly connected to the iron shell 10, the outer wall of the iron shell 10 fits the magnet ring 11, and the outer sleeve of the valve body 1 The first curved plate 13 is connected, and the side of the first curved plate 13 is fixedly connected to the support rod 19. The other end of the support rod 19 is provided with a magnet ring 11. The bottom shaft of the first curved plate 13 is connected to the second curved plate 14. The side of the first curved plate 13 is fixedly connected to the first fixing block 15. The side of the second curved plate 14 is fixedly connected to the second fixing block 17. The inner thread of the second fixing block 17 is connected to the butterfly bolt 16. The butterfly bolt 16 is tightened, and the butterfly bolt 16 is threadedly connected to the second fixing block 17, thereby pressing the first fixing block 15 downward, so that the first fixing block 15 and the second fixing block 17 are pressed toward the middle, driving the first curved clamping plate and the second curved clamping plate to press the valve body 1 toward the middle, thereby The first curved plate 13 and the second curved plate 14 are fixed to the outside of the valve body 1. When the water level drops to a certain height, the iron shell 10 on the surface of the float body 8 is adsorbed by the magnet ring 11. When the water level begins to rise, the buoyancy of the float body 8 is initially small. Because the iron shell 10 on the outside of the float body 8 is adsorbed by the magnet ring 11, the float body 8 will not rise with the water surface, so that the valve will not become smaller and the water injection speed will not decrease. As the water surface gradually rises and covers the float body 8, the buoyancy of the float body 8 gradually increases until the buoyancy is greater than the adsorption force of the magnet ring 11. The float body 8 will then break away from the suction of the magnet ring 11 and float upward, driving the float valve to gradually close, and the water injection efficiency will be faster during use.
