Abstract
Description
Technical Field
[0001] This invention relates to the field of ball valve technology, specifically to a ball valve with filtering function and corrosion resistance. Background Technology
[0002] The water entering the water supply company contains a large number of impurities, especially silt, sand, and weeds. This places demands on the valves in the pipeline, as impurities may damage the valves and reduce their service life. Therefore, it is necessary to filter the water before it passes through the valves. Ball valves are the preferred choice among valves because their sealing surfaces are resistant to the impact of silt, they have low opening and closing torque, are easy to operate, and have a long service life.
[0003] Currently, the ball valve is not equipped with a filtration structure. As a result, the solid impurities carried by the water entering the water company will affect the use of the ball in the valve. This will cause damage to the ball due to the adhesion of impurities during operation. At the same time, after a period of time, the filtered impurities will affect the water flow rate, making it difficult to monitor the water flow status in a timely manner and to clean the filtered impurities while maintaining the continuous use of water flow.
[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a ball valve with filtering function and corrosion resistance. Summary of the Invention
[0005] In view of the shortcomings of the prior art, the present invention provides a ball valve with filtering function and corrosion resistance, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a ball valve with filtration function and corrosion resistance, comprising an installation pipe and a connecting valve body. The connecting valve body has an internal filtration assembly for filtration, which includes a branch valve, a built-in filter screen, and a support column. The branch valve has an internal built-in filter screen, and a support column is installed in the middle of the built-in filter screen. An auxiliary assembly for continuous filtration is installed on the outside of the support column. The auxiliary assembly includes a first sealing disc, an installation disc, a filter cover, and a second sealing disc. The installation disc is located in the middle of the first sealing disc. The second sealing disc is installed on the outer surface of the support column away from the first sealing disc. A filter cover is provided between the first and second sealing discs. The installation pipe is threaded into the inside of the connecting valve body, and a pressure monitoring instrument is installed at the top of the installation pipe.
[0007] Furthermore, a second connecting disc is installed at one end of the connecting valve body, and a first connecting disc is provided on one side of the second connecting disc.
[0008] Furthermore, hexagonal bolts are arranged in a ring inside the connecting disc one and the connecting disc two, and a valve body is provided on one side of the connecting disc one.
[0009] Furthermore, a ball is provided inside the valve body, and the valve body is installed at both ends of the ball through sealing gaskets, and a valve handle is provided above the ball.
[0010] Furthermore, the first and second closed disks are exactly the same shape, and an installation disk is fixedly installed on one side of the outer surface of the second closed disk.
[0011] Furthermore, the shapes of the first and second closed discs match the shape and structure of the built-in filter, and the built-in filter is disposed on the outer surface of the first and second closed discs.
[0012] Furthermore, the end of the branch valve is provided with a sealing assembly for sealing the branch valve, and two sets of the sealing assembly are installed.
[0013] Furthermore, the sealing assembly includes an upper valve cover, two hexagonal bolts, a sealing gasket, and a lower valve cover. The outer surface of the upper valve cover is provided with a sealing gasket, and the outer surface of the sealing gasket is fitted with the lower valve cover. The upper valve cover and the lower valve cover are circumferentially distributed with two hexagonal bolts inside.
[0014] Furthermore, the filter cover has a semi-circular structure, and the upper valve cover or the lower valve cover is fixedly installed at both ends of the filter cover by screws.
[0015] Furthermore, a branch valve is fixedly installed at the end of the built-in filter screen by bolts, and the branch valve is integrally installed with a connecting valve body.
[0016] This invention provides a ball valve with filtering function and corrosion resistance, which has the following beneficial effects: 1. This corrosion-resistant ball valve with filtration function, through the design of a pressure sensor electrically connected to a pressure monitoring instrument, can monitor the flow rate and water pressure of tap water flowing into the valve body in real time. By observing changes in water pressure, the cleaning needs of the filter element can be determined. When tap water flows into the valve body, it first acts on the filter cover between the first and second closed discs. The design of the filter cover's shape and structure can filter out solid impurities in the tap water, effectively intercepting solid particles and protecting downstream equipment.
[0017] 2. This corrosion-resistant ball valve with filtration function can detect a slowdown in water flow using a pressure monitor. The upper and lower valve covers can be disassembled using the design of hexagonal bolts. Simultaneously, the user can use the mounting plate and bolts to allow the sealing plate one to slide downwards along the outside of the support column, so that the sealing plate two on the upper side of the support column abuts against the connection between the valve body and the branch valve. The sealing silicone gaskets on the outside of sealing plates one and two block the incoming water, facilitating cleaning of the filter cover for reuse. The filter cover is fixed to sealing plate one or sealing plate two with bolts, making it easy for the user to replace it according to wear and tear. During the cleaning of the filter cover, the incoming water is continuously filtered using the built-in filter screen, ensuring that the water flow is not interrupted during the cleaning process, reducing downtime costs.
[0018] 3. This filter-functional and corrosion-resistant ball valve, through the design of the number of sealing components, allows users to selectively choose the cleaning opening position when cleaning the filtered material, based on the installation location of the ball valve, thereby improving cleaning convenience and reducing limitations on cleaning positions.

[0021] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0022] like Figures 1-6As shown, the present invention provides a technical solution: a ball valve with filtering function and corrosion resistance, comprising a valve body 1, a valve handle 2, a pressure monitor 3, an installation pipe 4, a connecting valve body 5, a connecting disc 1 6, a hexagonal bolt 1 7, a connecting disc 2 8, a filter assembly 9, a branch valve 901, a built-in filter screen 902, a support column 903, a sealing assembly 10, an upper valve cover 1001, a hexagonal bolt 2 1002, a sealing gasket 1003, a lower valve cover 1004, an auxiliary assembly 11, and a sealing disc 1101. The valve body 5 is equipped with a mounting plate 1102, a filter cover 1103, a second sealing plate 1104, and a ball 12. A filter assembly 9 for filtration is located inside the valve body 5. The filter assembly 9 includes a branch valve 901, an internal filter screen 902, and a support column 903. A second connecting plate 8 is installed at one end of the valve body 5, and a first connecting plate 6 is located on one side of the second connecting plate 8. Hexagonal bolts 7 are arranged in a ring inside the first connecting plate 6 and the second connecting plate 8. A valve body 1 is located on one side of the first connecting plate 6. The valve body 1 contains a ball 12, with sealing gaskets at both ends of the ball 12. A valve handle 2 is located above the ball 12. The design of sealing gaskets on both the top and bottom of the ball 12 provides a double-sealing structure, improving sealing and durability. The branch valve 901 contains a built-in filter 902, with a support column 903 installed in the middle. The end of the built-in filter 902 is bolted to the branch valve 901, which is integrally mounted with the connecting valve body 5. The built-in filter 902 and the branch valve 901 form a detachable structure, allowing for easy fixing between the upper valve cover 1001 and the lower valve cover 1004 using hexagonal bolts 1002. In reverse operation, the upper valve cover 1001 and the lower valve cover 1004 can be separated, allowing the user to disassemble and clean the built-in filter 902 by loosening the bolts between it and the branch valve 901.The valve body 1, connecting valve body 5, and branch valve 901 are made of high-molecular materials such as polyethylene (PE), polyvinyl chloride (PVC), or polypropylene (PP), which have excellent chemical stability and can resist corrosion from acid, alkali, salt, and other corrosive media. Some high-end models use PTFE lining technology, extending the temperature range to -50℃ to 200℃, suitable for extreme working conditions. An auxiliary component 11 for continuous filtration is installed on the outside of the support column 903. The auxiliary component 11 includes a first sealing disc 1101, a mounting disc 1102, a filter cover 1103, and a second sealing disc 1104. The mounting disc 1102 is located in the middle of the first sealing disc 1101. The first sealing disc 1101 and the second sealing disc 1104 are identical in shape. A mounting plate 1102 is fixedly installed on one side of the outer surface of the second sealing plate 1104. The shapes of the first sealing plate 1101 and the second sealing plate 1104 match the shape and structure of the built-in filter screen 902. The built-in filter screen 902 is located on the outer surface of the first sealing plate 1101 and the second sealing plate 1104. The second sealing plate 1104 is installed at the end of the outer surface of the support column 903 away from the first sealing plate 1101. A filter cover 1103 is provided between the first sealing plate 1101 and the second sealing plate 1104. The mounting pipe 4 is threaded into the inside of the connecting valve body 5, and a pressure monitoring instrument 3 is provided at the top of the mounting pipe 4. Through the design of the pressure sensor electrically connected to the pressure monitoring instrument 3, the pressure monitoring of the connecting valve body 5 can be monitored in real time. The flow rate and pressure of tap water into valve body 1 can be monitored. Changes in water pressure indicate the need for cleaning the filter elements. When tap water flows into valve body 1, it first acts on the filter cover 1103 between closed disc one 1101 and closed disc two 1104. The shape and structure of the filter cover 1103 are designed to filter solid impurities in the tap water, effectively intercepting solid particles and protecting downstream equipment. When the pressure monitoring instrument 3 detects a slowdown in water flow, the design of hexagonal bolt two 1002 allows for the disassembly of the upper valve cover 1001 and the lower valve cover 1004. Simultaneously, the user can use the mounting plate 1102 and bolt design to allow closed disc one 1101 to move along the support column 9. 03. The outer surface slides downwards, causing the upper sealing disc 1104 of the support column 903 to abut against the connecting valve body 5 and the branch valve 901. The sealing disc 1101 and the sealing disc 1104 are slidably connected to the outer surface of the support column 903. Regarding the end position of the support column 903, one end is the upper end and the other end is the lower end. The user can use the design of the mounting disc 1102 and bolts to allow the sealing disc 1101 to move along the axial direction of the support column 903, specifically towards the lower end of the support column 903, moving along the axial direction of the outer surface of the support column 903 to the lower end of the support column 903. Similarly, the sealing disc 1104 moves along the axial direction of the outer surface of the support column 903 to the lower end of the support column 903.The design of the external sealing silicone gaskets of sealing disc 1101 and sealing disc 2 1104 isolates tap water, facilitating user cleaning of the filter cover 1103 for reuse. The filter cover 1103 is secured to either sealing disc 1101 or sealing disc 2 1104 with bolts, allowing for easy replacement based on wear. During the cleaning of the filter cover 1103, tap water is continuously filtered using the built-in filter screen 902, ensuring uninterrupted water flow during cleaning and reducing downtime costs.
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the end of the branch valve 901 is provided with a sealing assembly 10 for sealing the branch valve 901, and two sets of sealing assemblies 10 are installed. The sealing assembly 10 includes an upper valve cover 1001, hexagonal bolts 1002, a sealing gasket 1003, and a lower valve cover 1004. The outer surface of the upper valve cover 1001 is provided with a sealing gasket 1003, and the lower valve cover 1004 is installed on the outer surface of the sealing gasket 1003. Hexagonal bolts 1002 are distributed in a ring inside the upper valve cover 1001 and the lower valve cover 1004. The filter cover 1103 has a semi-circular structure. The upper valve cover 1001 or the lower valve cover 1004 is fixedly installed at both ends of 03 by screws. The design of the hexagonal bolts 1002 facilitates the fixed installation between the upper valve cover 1001 and the lower valve cover 1004. The design of the sealing gasket 1003 between the upper valve cover 1001 and the lower valve cover 1004 improves the sealing performance between the two, ensuring the stable use of the ball valve. The sealing assembly 10 is provided with two sets, which allows the user to selectively select the opening position for cleaning when cleaning the filtered material according to the installation position of the ball valve, thereby improving the ease of cleaning.
[0024] In summary, as Figures 1-6As shown, this filter-functional and corrosion-resistant ball valve, in use, has its valve body 1, connecting valve body 5, and branch valve 901 made of high-molecular materials such as polyethylene (PE), polyvinyl chloride (PVC), or polypropylene (PP), possessing excellent chemical stability and resisting corrosion from acids, alkalis, salts, and other corrosive media. Some high-end models use PTFE lining technology, extending the temperature resistance range to -50℃ to 200℃, suitable for extreme working conditions. The ball 12 has a double-sealing structure due to the sealing gaskets located on both the top and bottom, which, through pressure... The pressure sensor, electrically connected to the monitoring instrument 3, can monitor the flow rate and water pressure of tap water from valve body 5 to valve body 1 in real time. Changes in water pressure indicate the need for filter cleaning. When tap water flows into valve body 1, it first acts on the filter cover 1103 between closed disc 1101 and closed disc 1104. The shape and structure of the filter cover 1103 effectively filters solid impurities in the tap water, intercepting solid particles and protecting downstream equipment. The pressure monitoring instrument 3 can also monitor the water flow rate. When the flow rate decreases, the upper valve cover 1001 and the lower valve cover 1004 can be disassembled using the design of hex bolt 1002. Simultaneously, the user can use the design of the mounting plate 1102 and bolts to allow the sealing plate 1101 to slide downwards along the outside of the support column 903. This allows the sealing plate 1104 on the upper side of the support column 903 to abut against the connection between the valve body 5 and the branch valve 901. The sealing silicone gasket design on the outside of the sealing plate 1101 and the sealing plate 1104 blocks the flow of tap water, facilitating user operation of the filter. The filter cover 1103 is cleaned for reuse. The filter cover 1103 is fixed to the sealing disc 1101 or the sealing disc 1104 by bolts, which also makes it easy for the user to replace it according to the wear and tear. During the cleaning of the filter cover 1103, the tap water can be continuously filtered by the built-in filter screen 902 to ensure that the water flow is not interrupted during the cleaning of the filter. The built-in filter screen 902 is equipped with a metal support to ensure the stability of the tap water when using the built-in filter screen 902 to filter the tap water. Finally, when cleaning the filter material, the design of the hexagonal bolt 1002 facilitates the fixed installation between the upper valve cover 1001 and the lower valve cover 1004. The design of the sealing gasket 1003 between the upper valve cover 1001 and the lower valve cover 1004 improves the sealing performance between the two, ensuring the stable use of the ball valve. Furthermore, the sealing assembly 10 is provided with two sets, allowing the user to selectively choose the opening position for cleaning the filter material according to the installation position of the ball valve.
