Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an adjustable flow valve. Background Technique

[0002] A valve is a device used to control the flow of fluids in a pipeline. By adjusting the relative position or opening degree between the valve core and the valve seat, functions such as opening, closing, flow regulation, and pressure control of the fluid can be achieved. It is widely used in many fields such as industry, civil buildings, and municipal engineering. It is an essential component in the fluid transportation system and can effectively ensure the safe, stable, and efficient operation of the fluid system;

[0003] A ball valve is a type of valve that controls the on-off of fluid by rotating a sphere. It consists of a valve body, a sphere with a through-hole, and a valve stem. When the through-hole of the sphere is aligned with the pipeline direction, the valve opens, and when it is perpendicular, the valve closes. The ball valve has the characteristics of a compact structure, good sealing performance, fast and convenient operation, and a long service life. It is widely used in many fields such as petroleum, chemical industry, water supply and drainage, and natural gas, and is suitable for the control of various fluid media;

[0028] An adjustable flow valve includes a valve assembly 2. A flow control assembly 1 is fixedly connected to the upper end of the valve assembly 2.

A double-column hole 26 is formed in the inner side of the valve housing 21.

[0029] As a further implementation of this solution, the flow control assembly 1 includes a control housing 11. A servo motor 12 is fixedly connected to the inner side of the control housing 11. A worm 13 is fixedly connected to the end of the main shaft of the servo motor 12. The outer side of the worm 13 meshes with the outer side of a turbine 14. A connecting rod 15 is fixedly connected to the inner side of the turbine 14. A sphere 16 is fixedly connected to the bottom end of the connecting rod 15. Through the above settings, this structural design enables the worm 13, the turbine 14, and the connecting rod 15 to rotate in sequence when the servo motor 12 is started by the controller, and finally realizes the rotation of the sphere 16, thereby controlling the fluid flow. This transmission mechanism improves the stability and accuracy of valve operation.

[0030] As a further implementation of this solution, a rubber sealing ring 22 is fixedly connected to the inner side of the valve housing 21. An extension cylinder 23 is fixedly connected to the top end of the valve housing 21. A first bearing 24 and a first rubber sealing ring 25 are fixedly connected to the inner side of the extension cylinder 23. The number of the rubber sealing rings 22 is two. Through the above settings, the fixed connection of the rubber sealing rings 22 and the first rubber sealing ring 25 ensures the sealing performance when the fluid flows inside the valve housing 21 and prevents fluid leakage. The fixed connection of the first bearing 24 improves the stability when the connecting rod 15 rotates.

[0031] As a further implementation of this solution, the bottom end of the control housing 11 is fixedly connected to the top end of the extension cylinder 23. The connecting rod 15 extends out of the lower end of the control housing 11. The outer side of the connecting rod 15 is fixedly connected to the inner side of the first bearing 24. The outer side of the connecting rod 15 is in contact with the inner side of the first rubber sealing ring 25. The connecting rod 15 extends into the inner side of the valve housing 21. The outer side of the sphere 16 is in contact with the inner side of the rubber sealing ring 22. Through the above settings, this connection method ensures the sealing performance when the valve is closed and the smoothness of fluid flow when the valve is opened.

[0032] As a further implementation plan of this solution, the double-column holes 26 penetrate through the inner side of the valve housing 21. The double-column holes 26 communicate with the inner side of the valve housing 21. Double-column holes 26 are provided at both the upper and lower ends of the valve housing 21. The number of the first permanent magnet blocks 28 is multiple, and the number of the arc-shaped plates 31 is multiple. The arc-shaped plates 31 are embedded and installed inside the valve housing 21. The edge of the arc-shaped plate 31 away from the rotating column 33 is a chamfer structure. The upper and lower ends of the rotating column 33 respectively extend into the double-column holes 26.

The number of the second permanent magnet blocks 34 is the same as that of the first permanent magnet blocks 28. The second permanent magnet blocks 34 are magnetically attracted to the first permanent magnet blocks 28. The inner side of the second rubber sealing ring 27 is in contact with the outer side of the rotating column 33. Through the above settings, the arrangement of multiple arc-shaped plates 31 helps to disperse the fluid impact force. The chamfer structure can reduce the direct impact of the fluid on the valve, reduce noise and vibration, and improve the durability of the valve. The extension of the rotating column 33 and its fixed connection with the second bearing 35 help to improve the sealing performance of the valve. The magnetic attraction between the second permanent magnet blocks 34 and the first permanent magnet blocks 28 can increase the resistance when the rotating column 33 rotates, further reduce the fluid impact force, reduce vibration and noise, and improve the stability and safety of the system.

[0033] Working process: When controlling the flow rate of the valve, the servo motor 12 is started by the controller. The servo motor 12 drives the worm 13 to rotate. The worm 13 is rotatably connected to the inner side of the control housing 11. The control housing 11 drives the meshing turbine 14 on the outer side to rotate. The turbine 14 drives the connecting rod 15 to rotate. The connecting rod 15 is rotatably connected to the extension cylinder 23 through the first bearing 24, which can improve the stability when the connecting rod 15 rotates. The connecting rod 15 rotates to drive the sphere 16 to rotate. By controlling the angle of the sphere 16, the size of the flow rate passing through the inside of the valve housing 21 is controlled. The outer side of the sphere 16 is in contact with the inner side of the rubber sealing ring 22, which plays a role in sealing between the sphere 16 and the valve housing 21. The first rubber sealing ring 25 plays a role in sealing between the valve housing 21 and the connecting rod 15. The right end of the valve housing 21 is set as the inlet of the flow rate, and the left end of the valve housing 21, that is, the end close to the protection component 3, is the outlet of the flow rate. When the fluid flow rate is the largest, it will pass through the inside of the sphere 16 and then flow out from the hollow groove 32.

[0034] After the flow rate through the inside of the valve housing 21 becomes smaller, according to the Bernoulli equation, the flow rate of the fluid will increase at this time because the channel through the inside of the sphere 16 becomes narrower. At this time, the speed of the fluid flowing out of the inside of the sphere 16 will increase, so that the inside of the valve housing 21 will produce greater noise and vibration. If it cannot be controlled, it will affect the stability of the connection between the valve housing 21 and other pipelines. According to the same principle, the fluid ejected from the inside of the sphere 16 will collide with the arc plate 31. Under the impact of the fluid, the arc plate 31 is driven to rotate. Because after the sphere 16 rotates, the fluid flowing out of the sphere 16 is close to the edge of the valve housing 21. When the arc plate 31 rotates, it will drive the rotating column 33 to rotate, and the rotating column 33 The second bearing 35 is rotatably connected to the inside of the valve housing 21, and the second rubber sealing ring 27 serves to seal the rotating column 33 and the valve housing 21. The rotation of the rotating column 33 drives the second permanent magnet block 34 to rotate. Since the second permanent magnet block 34 will generate magnetic attraction with the first permanent magnet block 28, the resistance of the rotating column 33 during rotation can be increased under the action of the magnetic attraction force, thereby increasing the resistance to the rotation of the arc plate 31. The arc plate 31 is blocked to greatly reduce the speed of the fluid, thereby relieving the impact force of the fluid, which will significantly reduce the amplitude of vibration generated by the valve housing 21, improve the stability of the connection between the valve housing 21 and the pipeline, and the safety of the device.
