Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a ball valve that facilitates flow control. Background Technology

[0002] A ball valve is a type of valve that controls the flow of fluid by rotating a ball. Its working principle is that the ball is driven by the valve stem and rotates around the valve's axis. When the ball rotates 90 degrees, the valve can be opened or closed. The opening and closing element of a ball valve is a ball with a circular through-hole. Fluid flow is controlled by rotation. Traditional ball valves mostly control the flow rate by controlling the rotation angle of the opening and closing element, which is a relatively simple control method and has poor control effect. To better control the flow rate of liquid within the valve body, a ball valve that facilitates flow control is proposed.

[0003] As disclosed in CN216867574U, a ball valve for easy flow control includes a housing, a valve ball rotatably mounted inside the housing, a channel inside the valve ball, a valve stem fixed to the top of the valve ball, the valve stem being inserted into a mounting tube that rotatably engages with it, a rectangular rod coaxially fixed to the upper end of the valve stem, a control ring slidably engaged with the rectangular rod being fitted on the rectangular rod, two operating rods being fixedly connected to the control ring, an end block fixed to the upper end of the rectangular rod, a spring fitted on the rectangular rod between the end block and the control ring, grooves arranged in an annular array on the lower end face of the control ring, and blocks arranged in an annular array on the upper end face of the mounting tube, each block engaging into one of the grooves.

[0004] While it enables convenient flow control of ball valves, it does not solve the problem that existing ball valves are not conducive to the quick and easy removal and installation of filter screens and the convenient linkage adjustment of water flow in the pipeline. This hinders the filtration of water flow inside the pipeline and the flexible adjustment of liquid flow, thus affecting the flexibility of liquid flow control. Utility Model Content

[0005] The purpose of this invention is to provide a ball valve that facilitates flow control, thereby addressing the problem mentioned in the background art that ball valves are not convenient for quick and easy disassembly and assembly of filter screens and convenient linkage adjustment of water flow in pipelines, which hinders the filtration of water flow inside pipelines and the flexible adjustment of liquid flow, thus affecting the flexibility of liquid flow control.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ball valve for convenient flow control, comprising a valve body and an adjusting pipe. The adjusting pipe is installed at the port position of the valve body and is fixedly connected to the valve body. A servo motor is installed at the top of the valve body. An opening and closing component is movably arranged inside the valve body and is connected to the output end of the servo motor. A conical filter screen is arranged inside the opening and closing component. Four sets of equally spaced snap-fit ​​grooves are installed on the inner wall of the opening and closing component. Four sets of equally spaced snap-fit ​​blocks are installed on the outer wall of the conical filter screen, and the snap-fit ​​blocks correspond to the snap-fit ​​grooves and are slidably connected to the snap-fit ​​grooves.

[0007] Preferably, the inside of the adjusting tube is provided with a support block, and the support block is connected to the adjusting tube through a cross. Multiple sets of adjusting blades with equal spacing are installed on the side wall of the support block, and the adjusting blades are movably connected to the support block.

[0008] Preferably, an electric push rod is installed on the outer wall of the adjusting tube, and a push arm is installed at the output end of the electric push rod.

[0009] Preferably, a slip ring is provided at the end of the push arm away from the electric push rod, and the slip ring is slidably connected to the adjusting tube.

[0010] Preferably, a pin is provided on the side of the slip ring near the push arm, and the push arm is movably connected to the slip ring through the pin.

[0011] Preferably, multiple sets of linkage arms with equal spacing are installed on the outer wall of the slip ring. Each linkage arm is provided with a hinge shaft at one end near the slip ring, and the linkage arm is movably connected to the slip ring through the hinge shaft.

[0012] Preferably, each of the linkage arms is provided with an adjusting arm at the end away from the slip ring, and each of the adjusting arms is provided with a movable shaft at the end near the linkage arm, and the adjusting arm is movably connected to the linkage arm through the movable shaft.

[0013] Preferably, the end of the adjusting arm away from the linkage arm is fixedly installed with a linkage shaft, and the linkage shaft is movably connected to the adjusting tube and connected to the adjusting blade.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the ball valve not only realizes the convenient and quick disassembly and assembly of the filter screen and the linkage adjustment of the water flow rate in the pipeline, which facilitates the filtration of the water flow inside the pipeline and the flexible adjustment and control of the liquid flow rate, but also improves the flexibility of adjusting and controlling the liquid flow rate.

[0015] (1) First, take the conical filter screen, align the snap-fit ​​block with the snap-fit ​​groove, move the conical filter screen, and let the conical filter screen drive the snap-fit ​​block to slide inside the snap-fit ​​groove. When the snap-fit ​​block moves to the corner of the snap-fit ​​groove, rotate the conical filter screen clockwise, and let the conical filter screen drive the snap-fit ​​block to rotate inside the snap-fit ​​groove, so that the snap-fit ​​block is snapped into the inside of the snap-fit ​​groove, thereby installing the conical filter screen inside the opening and closing part. The conical surface of the conical filter screen faces the direction of water flow, which can effectively withstand the pressure of water flow. Then connect the adjusting pipe to the valve body and connect it to the pipeline, and open. The servo motor drives the opening and closing component to rotate, aligning the orifice of the component with the direction of water flow, thereby opening the ball valve. Water flows through the orifice inside the opening and closing component, filtering impurities from the water flow through the conical filter screen. When the conical filter screen needs to be replaced, the valve body is removed, and then the conical filter screen is rotated counterclockwise and pulled out to remove it from inside the opening and closing component. A new conical filter screen can then be replaced. This allows for convenient and quick removal and installation of the filter screen, facilitating the filtration of water flow inside the pipeline.

[0016] (2) The push arm is moved by the electric push rod, and the push arm drives the slip ring to slide on the surface of the adjusting tube through the pin shaft. The slip ring drives the linkage arm to rotate through the hinge shaft, and the linkage arm drives the adjusting arm to rotate through the movable shaft. The adjusting arm drives the adjusting blade to rotate through the linkage shaft. Under the synchronous closed rotation of multiple sets of adjusting blades, the size of the flow channel inside the adjusting tube is adjusted, thereby adjusting the liquid flow rate. This realizes convenient linkage adjustment of the liquid flow rate, facilitates flexible adjustment of the liquid flow rate, and improves the flexibility of controlling the liquid flow rate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-6 The present invention provides an embodiment of a ball valve for convenient flow control, comprising a valve body 1 and an adjusting pipe 2. The adjusting pipe 2 is installed at the port of the valve body 1 and is fixedly connected to the valve body 1. A servo motor 3 is installed at the top of the valve body 1, which serves as a power drive. An opening and closing component 15 is movably arranged inside the valve body 1 and is connected to the output end of the servo motor 3. A conical filter screen 16 is arranged inside the opening and closing component 15. Four sets of equally spaced snap-fit ​​grooves 18 are installed on the inner wall of the opening and closing component 15. Four sets of equally spaced snap-fit ​​blocks 17 are installed on the outer wall of the conical filter screen 16, and the snap-fit ​​blocks 17 correspond to the snap-fit ​​grooves 18 and are slidably connected to the snap-fit ​​grooves 18.

[0026] First, take the conical filter screen 16, align the snap-fit ​​block 17 with the snap-fit ​​groove 18, and move the conical filter screen 16. The conical filter screen 16 will drive the snap-fit ​​block 17 to slide inside the snap-fit ​​groove 18. When the snap-fit ​​block 17 moves to the corner of the snap-fit ​​groove 18, rotate the conical filter screen 16 clockwise. With the sliding cooperation between the snap-fit ​​block 17 and the snap-fit ​​groove 18, the conical filter screen 16 will drive the snap-fit ​​block 17 to rotate inside the snap-fit ​​groove 18, thus snapping the snap-fit ​​block 17 into place inside the snap-fit ​​groove 18. This installs the conical filter screen 16 inside the opening and closing part 15. The conical surface of the conical filter screen 16 faces the direction of water flow, effectively withstanding the pressure of the water flow. Then connect the adjusting pipe 2 to the valve body. Connect the valve body 1 to the pipeline, turn on the servo motor 3, and the servo motor 3 drives the opening and closing part 15 to rotate, so that the position of the hole of the opening and closing part 15 is rotated in the direction of water flow, thereby opening the ball valve. Water flows through the hole inside the opening and closing part 15, and at the same time, under the filtering action of the conical filter screen 16, the impurities in the water flow are filtered. When it is necessary to replace the conical filter screen 16, remove the valve body 1, then rotate the conical filter screen 16 counterclockwise, pull out the conical filter screen 16, and then replace it with a new conical filter screen 16. This realizes convenient and quick disassembly and assembly of the filter screen, which facilitates the filtration of water flow inside the pipeline.

[0027] The inside of the adjusting tube 2 is provided with a support block 4, and the support block 4 is connected to the adjusting tube 2 through a cross. Multiple sets of adjusting blades 5 with equal spacing are installed on the side wall of the support block 4, and the adjusting blades 5 are movably connected to the support block 4.

[0028] An electric push rod 7 is installed on the outer wall of the adjusting tube 2. A push arm 8 is installed at the output end of the electric push rod 7. A slip ring 6 is provided at the end of the push arm 8 away from the electric push rod 7. The slip ring 6 is slidably connected to the adjusting tube 2. A pin 14 is provided on the side of the slip ring 6 near the push arm 8. The push arm 8 is movably connected to the slip ring 6 through the pin 14.

[0029] Multiple sets of linkage arms 10 with equal spacing are installed on the outer wall of the slip ring 6. Each linkage arm 10 is provided with a hinge shaft 9 at one end near the slip ring 6, and the linkage arm 10 is movably connected to the slip ring 6 through the hinge shaft 9.

[0030] An adjusting arm 12 is provided at the end of the linkage arm 10 away from the slip ring 6, and a movable shaft 11 is provided at the end of the adjusting arm 12 close to the linkage arm 10. The adjusting arm 12 is movably connected to the linkage arm 10 through the movable shaft 11.

[0031] The end of the adjusting arm 12 away from the linkage arm 10 is fixedly equipped with a linkage shaft 13, and the linkage shaft 13 is movably connected to the adjusting tube 2, and the linkage shaft 13 is connected to the adjusting blade 5.

[0032] When it is necessary to control the water flow rate, the electric push rod 7 is opened, which drives the push arm 8 to move. The push arm 8 drives the slip ring 6 to slide on the surface of the adjusting tube 2 through the pin shaft 14. The slip ring 6 drives the linkage arm 10 to rotate through the hinge shaft 9. The linkage arm 10 drives the adjusting arm 12 to rotate through the movable shaft 11. With the movable cooperation between the linkage shaft 13 and the adjusting tube 2, and with the movable cooperation between the adjusting blade 5 and the bearing block 4, the adjusting arm 12 drives the adjusting blade 5 to rotate through the linkage shaft 13. With the synchronous closing and rotation of multiple sets of adjusting blades 5, the size of the internal flow channel of the adjusting tube 2 is adjusted, thereby adjusting the liquid flow rate. This realizes convenient linkage adjustment of the liquid flow rate, facilitates flexible adjustment of the liquid flow rate, and improves the flexibility of controlling the liquid flow rate.

[0033] Working principle: First, take the conical filter screen 16 and align the locking block 17 with the locking groove 18. Move the conical filter screen 16, which will cause the locking block 17 to slide inside the locking groove 18. When the locking block 17 moves to the corner of the locking groove 18, rotate the conical filter screen 16 clockwise. With the sliding cooperation between the locking block 17 and the locking groove 18, the conical filter screen 16 will cause the locking block 17 to rotate inside the locking groove 18, thus locking the locking block 17 inside the locking groove 18. The conical filter screen 16 is installed inside the opening and closing element 15, with its cone facing the direction of water flow to effectively withstand the water pressure. Then, the adjusting pipe 2 is connected to the valve body 1 and the pipeline. The servo motor 3 is turned on, causing the opening and closing element 15 to rotate, thus rotating the orifice of the opening and closing element 15 to the direction of water flow, thereby opening the ball valve. Water flows through the orifice inside the opening and closing element 15, and simultaneously, the conical filter screen 16 filters the water. The ball valve is used to filter impurities in the water flow. When the conical filter screen 16 needs to be replaced, the valve body 1 is removed, and then the conical filter screen 16 is rotated counterclockwise and pulled out. The conical filter screen 16 can then be removed from the opening and closing part 15. After that, a new conical filter screen 16 can be replaced. When it is necessary to control the water flow rate, the electric push rod 7 is opened, and the electric push rod 7 drives the push arm 8 to move. The push arm 8 drives the slip ring 6 to slide on the surface of the adjusting pipe 2 through the pin shaft 14. The slip ring 6 drives the linkage arm 10 to rotate through the hinge shaft 9. The linkage arm 10 drives the adjusting arm 12 to rotate through the movable shaft 11. With the movable cooperation between the linkage shaft 13 and the adjusting pipe 2, and with the movable cooperation between the adjusting blade 5 and the bearing block 4, the adjusting arm 12 drives the adjusting blade 5 to rotate through the linkage shaft 13. With the synchronous closing and rotation of multiple sets of adjusting blades 5, the size of the flow channel inside the adjusting pipe 2 is adjusted, thereby adjusting the liquid flow rate. The above is the complete usage of the ball valve for convenient flow control.
