Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a ball valve with a filtering structure. Background Technology

[0002] The working principle of a ball valve is that the rotation of the valve stem drives the rotation of the ball, thereby opening and closing the valve. When the ball rotates 90 degrees, its circular channel aligns with the inlet and outlet of the pipeline, forming a passage that allows the medium to pass smoothly. When the ball rotates another 90 degrees, its circular channel is closed, thereby cutting off the flow of the medium.

[0003] Currently, to minimize internal wear of ball valves, a filter structure is typically designed at the front end of the pipeline to filter impurities. However, this filter structure is installed between the pipeline and the ball valve, making disassembly and assembly inconvenient. During regular cleaning, external tools such as wrenches are required to disassemble the filter structure, which is time-consuming and laborious. Repeated disassembly and assembly may also lead to poor sealing, causing water leakage at the ball valve location and reduced stability. To address the shortcomings of existing technologies, this utility model provides a ball valve with a filter structure to solve the above problems. Utility Model Content

No external tools such as wrenches are needed during the disassembly and assembly process. The disassembly and assembly process is simple and convenient, saving time and effort, thus making it easy to clean, replace and upgrade the filter box and filter screen regularly.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides a ball valve with a filter structure, which solves the problems of traditional ball valve filter structures being inconvenient to install and disassemble between the pipeline and the ball valve. During regular cleaning, external tools such as wrenches are required to disassemble the filter structure, which is time-consuming and laborious. Repeated disassembly and assembly may also lead to poor sealing, causing water leakage at the ball valve position and reduced stability.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model discloses a ball valve with a filtering structure, according to the attached... Figure 1-4 As shown, the device includes a ball valve body 1, and flanges 101 connected to external pipelines are provided at both ends of the ball valve body 1. The flanges 101 are fixed to the ends of the external pipelines by bolts.

[0024] The ball valve body 1 has an embedded groove 2 at its bottom. A filter box 3 is movably engaged inside the embedded groove 2. A filter screen 301 is provided on the filter box 3. A locking block 4 is fixedly connected to the bottom of the filter box 3. A rubber ring 401 is provided on the locking block 4. Through the design of the rubber ring 401, after the filter box 3 and the filter screen 301 are installed, the locking block 4 engages with the embedded groove 2 and squeezes the rubber ring 401 to form a seal at the interface.

[0025] The bottom of the ball valve body 1 is provided with a locking mechanism 5. The locking mechanism 5 is used to lock and limit the position of the locking block 4. The locking mechanism 5 includes a rail 501 and a positioning block 502 fixedly connected to the bottom of the ball valve body 1. A screw 503 is threadedly connected to the positioning block 502. A rotating handle 5031 is provided on the screw 503. A locking block 504 is rotatably connected to the screw 503. The locking block 4 is clamped between the two sets of locking blocks 504.

[0026] The device, through the locking mechanism 5, makes the installation of the filter box 3 and the locking block 4 convenient, time-saving and labor-saving, thereby making it easy to clean or maintain the filter box 3 and the filter screen 301 regularly.

[0027] When installing the filter box 3, first align the filter box 3 and the filter screen 301 with the inside of the embedding groove 2 and snap them together. At the same time, push the locking block 4 to snap it into place at the opening of the embedding groove 2. Then, rotate the lead screw 503 so that the lead screw 503 drives the locking block 504 to move laterally and so that the two sets of locking blocks 504 lock and limit the locking block 4, thereby realizing the installation of the filter box 3 and the locking block 4.

[0028] The guide rail 501 has a slot 5011, and the locking block 504 is fixedly connected to a slider 5041. The slider 5041 is slidably connected in the slot 5011. Through the design of the slot 5011 and the slider 5041, the locking block 504 is laterally supported and the force is stable.

[0029] A lateral support rod 5042 is fixedly connected to the locking block 504. The lateral support rod 5042 is slidably connected to the positioning block 502. Through the design of the lateral support rod 5042, the locking block 504 is subjected to secondary support and limitation, ensuring the stability of the force on the locking block 504 and the good locking effect on the locking block 4.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
