The valve ball is provided with a valve stem at the top, and the valve stem is provided with a valve cover at the top. The branch pipe is provided with a filter screen, and the filter screen extends into the interior of the valve body. Rotate the valve cover, and the valve cover drives the valve ball to move up and down relative to the valve seat to open and close the valve. By providing the filter screen, the impurities in the pipeline system are filtered.

[0005] However, the existing filter ball valve may only filter larger particles, and the filtering effect on micro-impurities is limited, which leads to the residue of micro-impurities. SUMMARY

[0013] By adopting the above technical scheme, in the pipeline or equipment system, the gas accumulation in the fluid may affect the stability of the flow or pressure, and even cause gas blocking problems. The gas can be effectively discharged through the steam discharge branch pipe to ensure stable operation of the system. After the gas is discharged, the liquid flows more smoothly, reducing resistance and improving the working efficiency of the fluid system. In a high-pressure or high-temperature environment, the gas generated due to temperature or pressure changes can be timely discharged to avoid equipment failure or damage caused by gas expansion. In a flammable and explosive gas system, timely discharge of gas can reduce the risk of dangerous gas accumulation and ensure safe operation.

[0014] Further arrangement, the first branch pipe is provided with a cylindrical filter screen, one end of the cylindrical filter screen extends to the second branch pipe, and the first branch pipe is detachably connected with the filter screen plug.

[0015] Further arrangement, the screen body of the cylindrical filter screen forms an opening, and the opening is opposite to the ball valve.

[0016] By adopting the above technical scheme, the cylindrical filter screen has a larger filtering area and can effectively filter impurities in the pipeline. By arranging the cylindrical filter screen, impurities can be prevented from entering the upper steam discharge branch pipe, causing the steam discharge branch pipe to be blocked, and thus the steam discharge function fails. Compared with the traditional flat filter screen, the cylindrical filter screen can provide longer and more stable filtering effect. The filter screen extends to the second branch pipe, which can more effectively capture impurities in the pipeline, further improving the filtering effect. Due to the shape and arrangement of the filter screen, the flow of fluid is guided through the entire surface of the filter screen, thereby more fully filtering. Through the detachable filter screen plug, users can easily disassemble the filter screen for cleaning or replacement. Users can easily check the status of the filter screen during operation, including whether a large amount of impurities has accumulated or needs to be replaced, thereby improving the use efficiency of the filter screen and the possibility of timely maintenance. The detachable design allows users to choose filter screens with different pore sizes (such as coarse filter screens or fine filter screens) according to actual needs, customize the most suitable filtering solution according to the types and particle sizes of impurities in the fluid, and improve the filtering effect.

[0017] Further arrangement, the filter screen plug is a plug cover.

[0018] By adopting the above technical scheme, the plug cover as the filter screen plug has a detachable design, allowing users to quickly disassemble it during cleaning and maintenance. Before disassembly, the limit switch handle is closed to stop water inflow, the plug cover is removed, and a hose with a union nut can be directly connected to directly open the limit handle switch for sewage discharge. The plug cover not only plays a role in closing the filter screen, but also effectively prevents impurities or particulate matter in the pipeline from leaking to the outside of the system, ensuring the sealing and cleanliness of the pipeline system, avoiding liquid or gas leakage, ensuring smooth flow of fluid, avoiding leakage problems caused by poor sealing, and thus improving the safety and stability of the system.

[0019] Further, the filter screen plug includes a connecting piece, and a magnet is arranged in the connecting piece.

[0020] By adopting the above technical scheme, the magnet arranged in the connecting piece is magnetically connected with the second magnet plug cover, so that the plug cover and the sealing part of the valve body can be more closely connected. This magnetic sealing structure can effectively prevent leakage and provide more reliable anti-leakage capability than traditional sealing.

[0021] Further, the sewage suction branch pipe port is provided with a magnet plug cover, and the sewage suction branch pipe is detachably connected with the first magnet plug cover.

[0022] By adopting the above technical scheme, the magnet plug cover is designed to be detachable, allowing users to easily detach it when needed for cleaning or replacing the magnet. This ensures that the magnet and the inside of the sewage suction branch pipe do not accumulate impurities, improving the adsorption effect of the magnet. By detaching the magnet plug cover, impurities or sediments inside the sewage suction branch pipe can be directly cleaned, keeping the performance of the magnet at its best and prolonging its service life. Since the magnet plug cover is detachable, users can choose whether to install a magnet or replace a magnet with different adsorption strength according to actual needs, providing more flexibility for the equipment. The type or adsorption strength of the magnet can be adjusted according to the types of impurities in the fluid (such as metal, iron filings, etc.). With the development of technology and the improvement of magnet materials and adsorption capacity, users can upgrade the magnet by simply detaching and replacing the plug cover, further improving the performance of the filter steam ball valve without the need to replace the entire valve or system.

[0023] Further, the handle forms a limiting part, and the valve body is provided with a limiting block, and the limiting part cooperates with the limiting block.

[0024] By adopting the above technical scheme, the limiting part cooperates with the limiting block to limit the rotation angle of the handle, avoiding excessive rotation or opening of the valve ball, protecting the sealing surface of the valve ball and valve seat, and preventing seal damage or excessive wear of internal components of the valve body caused by excessive rotation. By limiting the rotation angle of the handle, the valve components will not be subjected to excessive mechanical load, reducing fatigue damage caused by excessive operation. The cooperation of the limiting part and the limiting block ensures accurate control of the opening and closing of the valve ball. When the handle reaches the limit, the valve ball will be fully opened or closed, avoiding instability during valve operation and ensuring that the fluid control system is always in the desired working state. The rotation of the handle is limited, which can avoid incomplete opening or closing of the valve due to improper operation, thereby effectively avoiding fluid leakage or other safety hazards. For high-pressure or dangerous fluid systems, it prevents operators from misoperation.

[0025] Further, the valve body is provided with a valve seat, and the valve ball is located in the valve seat, and a sealing ring is arranged between the valve seat and the valve ball.

[0026] By adopting the above technical scheme, the sealing ring is arranged between the valve seat and the valve ball, the sealing ring as an elastic sealing element can effectively fill the small gap between the valve seat and the valve ball, ensure that the fluid does not leak, and enhance the sealing performance of the valve. The sealing ring can provide stronger sealing effect when the valve ball is closed, avoiding the leakage of fluid in the closed state. The sealing ring can reduce the direct contact between the valve ball and the valve seat, reducing wear and corrosion.

[0027] Further, the second branch pipe port is provided with a plug, and the second branch pipe is detachably connected with the plug.

[0028] By adopting the above technical scheme, the detachable plug of the second branch pipe port allows maintenance personnel to conveniently inspect, clean or replace the second branch pipe. After long-term use, dirt or impurities may accumulate inside the pipeline, and the plug can be easily removed for cleaning, thereby avoiding blockage or flow restriction. The plug of the second branch pipe port can be detached, and users can flexibly adjust the system structure or pipeline configuration as needed. The plug of the second branch pipe port can effectively prevent external substances from entering the pipeline, reducing the risk of pipeline system being contaminated by external pollution, and avoiding unnecessary pipeline corrosion or fouling.

[0029] Further, the valve seat port is externally threaded.

[0030] By adopting the above technical scheme, after the valve seat port is externally threaded, users can directly thread it with pipelines or other fittings having corresponding internal threads, simplifying the installation process of the valve seat, avoiding welding or other complex connection methods, and reducing the difficulty and time cost of installation. The threaded connection method does not require special welding tools or high-technology equipment, and installation personnel can use conventional tools (such as wrenches) for installation, reducing installation costs. Through threaded connection, the connection between the valve seat and the pipeline is more secure. The tightening effect of the threads can ensure that the connection between the valve seat and the pipeline is stable and reliable, avoiding leakage problems caused by loose connection. Threaded connection often provides higher sealing performance than other connection methods (such as flange connection or welding), and is particularly suitable for high-pressure or high-flow environments that require prevention of liquid or gas leakage.

[0056] Valve body 1 is equipped with end cover 1-1 at one end, and valve body 1 is detachably connected with end cover 1-1.

[0057] As shown in the drawings, Figures 9-10 Handle 6 forms limiting part 6-1, and valve body 1 is equipped with limiting block 6-2, and limiting part 6-1 cooperates with limiting block 6-2.

[0058] As shown in the drawings, Figure 2As shown, a valve seat 1-2 is provided inside the valve body 1, and a valve ball 4 is located on the valve seat 1-2. A sealing ring 1-3 is provided between the valve seat 1-2 and the valve ball 4. Threads are formed on the outside of the valve seat 1-2 port.

[0059] like Figure 1 As shown, a plug 3-1 is installed at the port of the second branch pipe 3, and the second branch pipe 3 is detachably connected to the plug 3-1.

The rotation of the valve ball 4 changes the position of the valve ball passage 4-1, controlling the passage or closure of fluid, thus realizing the on / off control of the valve body.

[0061] A magnet 8 is installed inside the suction branch pipe 7. The port of the suction branch pipe is sealed by a magnetic plug 9, and the plug 9 is detachably connected to the suction branch pipe 7. When fluid passes through the valve body 1, the magnet 8 can attract metal particles or other magnetic impurities in the pipe, preventing these impurities from entering the downstream section of the pipe. This effectively reduces the potential damage of metal impurities in the pipe to downstream equipment and reduces the burden on the filter screen. The magnet 8 helps reduce the accumulation of impurities and improves the overall filtration effect.

[0062] A cylindrical filter screen 2-1 is installed inside the first branch pipe 2, with one end extending into the second branch pipe 3. The port of the first branch pipe is sealed by a filter screen plug 2-2, which is a removable cap. When fluid passes through the valve body 1, the filter screen 2-1 filters out impurities.

The removable filter screen plug 2-2 allows users to easily inspect, clean, or replace the filter screen. Users can select filter screens with different pore sizes to customize the filtration scheme and improve the system's filtration performance.

[0063] A valve seat 1-2 is provided inside the valve body 1, and a valve ball 4 is located on the valve seat 1-2. The valve seat and the valve ball are sealed by a sealing ring 1-3.

The use of the sealing ring 3-1 can significantly improve the sealing performance of the valve and reduce fluid leakage in the closed state.

[0064] The end of the valve body 1 is equipped with an end cover 1-1, and the valve body and the end cover are connected through detachable connection. The detachable end cover 1-1 is designed to allow users to easily disassemble and maintain the valve body 1. When maintenance, cleaning or replacement is needed, users only need to disassemble the end cover 1-1 to access the inside of the valve body 1 for operation. The disassembly process is simple, easy to clean and maintain, and ensures the long-term stable operation of the valve. The end cover 1-1 forms a steam branch pipe 1-1-1, which is in communication with the inside of the valve body 1, and the steam branch pipe 1-1-1 is provided with a steam end cover 1-1-2, and the steam branch pipe 1-1-1 and the steam end cover 1-1-2 are detachably connected.

[0065] The handle 6 forms a limiting part 6-1, and the valve body 1 is provided with a limiting block 6-2, which cooperates with the limiting part 6-1 to limit the rotation angle of the handle 6. The limiting part 6-1 cooperates with the limiting block 6-2 to limit the rotation angle of the handle 6, thereby avoiding excessive rotation of the valve ball 4. This prevents the valve ball 4 from being excessively opened or closed, protects the sealing ring 1-3 between the valve body 1 and the valve seat 1-2, and avoids damage to the seal or wear of the internal components due to excessive rotation. At the same time, it also ensures the operation accuracy of the valve, avoids fluid leakage caused by misoperation or incomplete closing.

[0066] The port of the valve seat 1-2 is externally threaded, which facilitates connection with pipes or other fittings. Through threaded connection, the valve seat 1-2 can be directly connected with pipes or fittings having corresponding internal threads, which simplifies the installation process of the valve seat 1-2 and avoids complex welding or other connection methods. Threaded connection also provides higher sealing performance, ensuring stable and reliable connection between the pipe and the valve seat, reducing the risk of leakage.

[0067] Example 1 can be used in cold water or hot water pipes. During the operation of the filter steam ball valve, the rotation of the valve ball 4 controls the on-off of the fluid, and the rotation of the valve ball passage 4-1 realizes the flow control of the fluid. At the same time, the magnet 8 improves the filtering effect by adsorbing magnetic impurities, and the cylindrical filter screen 2-1 further filters non-magnetic impurities. The detachable design facilitates maintenance and cleaning, and the cooperation of the handle 6 limiting part 6-1 and the limiting block 6-2 protects the safety of the valve body and the sealing system.

[0069] In the embodiment 2, the magnet 8 is also arranged inside the connecting piece 2-2-1, which makes the whole filter screen blocking piece 2-2 have stronger magnetic adsorption capacity when closing the filtering system. By integrating the magnet 8 in the filter screen blocking piece 2-2, metal impurities or magnetic particles in the pipeline can be effectively adsorbed. Even if there are finer metal substances in the fluid, they can be adsorbed by the magnet 8, further improving the effect of the filtering system. The adsorption effect of the magnet 8 enhances the efficiency of fluid purification, which can ensure that the filter removes magnetic impurities more efficiently and reduces the potential harm of these impurities to subsequent pipelines or equipment. The second magnet blocking cover 2-2-2 combined with the connecting piece 2-2-1 can provide stronger sealing force through magnetic force, enhance the sealing performance, and ensure more secure fixation through magnetic force to prevent the blocking cover from loosening. The cooperation of the magnet not only enhances the convenience of disassembly and installation of the filter screen blocking piece, but also improves the sealing performance to ensure that leakage is less likely to occur during use.

[0070] Compared with the embodiment 1, the embodiment 2 adds the magnet 8 in the filter screen blocking piece 2-2, which not only improves the magnetic adsorption effect, but also enhances the sealing performance, stability, and operation convenience of the system. The use of the magnet 8 makes the filtering system more efficient and durable, and simplifies the maintenance operation.
