Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a valve with a self-generating system. Background Art

[0002] A valve is a mechanical device used to control the flow of fluids (such as liquids, gases or slurries). It can control the flow, pressure and direction by opening, closing or adjusting the passage of the fluid. Valves are widely used in various industries, construction and transportation fields. Common types include ball valves, gate valves, stop valves, butterfly valves, etc. The choice of valves is usually determined by the fluid characteristics, working pressure, temperature and specific application requirements.

[0003] An electronic control valve is a device that uses electronic technology to achieve precise control of fluid flow. Compared with traditional mechanical valves, it has higher precision and faster response capabilities. By connecting to control systems such as PLC and DCS, electronic control valves can achieve remote monitoring and automated operation. The sensors they are equipped with can also monitor flow and pressure in real time and make automatic adjustments, thereby improving the energy efficiency of the system. This type of valve is widely used in industrial process control, HVAC, and water treatment, significantly improving the efficiency and safety of the system.

[0004] The existing electric control valves also have the following technical problems: The dependence of electric control valves on electricity brings significant disadvantages, mainly including the risk of power outages, the need for backup power supplies and power quality issues. Power outages can cause valve failures, especially in the chemical and petroleum industries, which may cause safety accidents. To address this risk, a backup power supply needs to be installed, which increases the initial investment and maintenance costs.

When water flow or gas passes through the runner blade 11, it is caused to rotate. At this time, the positioning ring 12 at the outer end of the runner blade 11 drives the first permanent magnet 13 to rotate. During the rotation of the first permanent magnet 13, electromagnetic induction is generated with the stator winding 6, and then the electric energy is converted and collected by the battery 14.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] Embodiment 1:

[0037] Please refer to Figure 2-Figure 5 A valve with a self-generating system, the self-generating mechanism 3 includes a stator winding 6, an annular protective cover 7, a supporting assembly and a rotating power generation assembly, the surface of the flange 2 is fixedly connected with the stator winding 6, the stator winding 6 itself is annular and has multiple groups of copper wire windings in the middle, and the outer surface of the stator winding 6 is fixedly covered with an annular protective cover 7

[0038] Specifically, the support assembly includes a support positioning frame 8 and a positioning shaft 9. The inner wall of the docking pipe 1 is fixedly connected with the support positioning frame 8. There are two support positioning frames 8 and they are symmetrically arranged on the inner wall of the docking pipe 1. The middle parts of the two support positioning frames 8 are rotatably connected with the positioning shaft 9. The two support positioning frames 8 are arranged in the same position as the stator winding 6 arranged on the outer wall of the docking pipe 1.

[0039] Specifically, the rotating power generation assembly includes a fixed sleeve 10, a runner blade 11 and a positioning ring 12.

The inner wall of the docking pipe 1 is rotatably connected to the positioning ring 12, and the positioning ring 12 is fixedly connected to one end of the runner blade 11 away from the fixed sleeve 10.

[0040] Specifically, a notch is formed on the outer wall of the positioning ring 12, and a plurality of first permanent magnets 13 are fixedly connected in a ring array in the middle of the notch. The first permanent magnets 13 are arranged alternately with positive and negative poles in the middle of the notch.

[0041] Specifically, a battery 14 is fixedly connected to the outer wall of the docking pipe 1 and the battery 14 itself is arc-shaped. The battery 14 is electrically connected to the stator winding 6 .

[0042] Through the above structural design, when the device is used, the flanges 2 on both sides are connected to the pipeline, and the water flow inside the docking pipeline 1 drives the runner blades 11 to rotate. The runner blades 11 rotate and drive the positioning ring 12 at the outer end to rotate on the inner wall of the docking pipeline 1. The positioning ring 12 rotates and drives the first permanent magnet 13 in the middle to rotate. Since the first permanent magnet 13 is arranged with positive and negative poles alternately, the first permanent magnet 13 can form electromagnetic induction through the externally arranged stator winding 6 while rotating, and is electrically connected to the stator winding 6 through the battery 14, so that the electricity generated by the stator winding 6 can be transmitted to the inside of the battery 14, thereby completing the storage of electrical energy while generating electricity by itself.

[0043] Embodiment 2:

[0044] The self-generating system of the valve provided in Example 1 is further optimized, specifically, as follows: Figure 5-Figure 7 As shown, the heat dissipation mechanism 4 includes a connecting support frame 15, a transmission ring frame 16, a heat dissipation component and a traction component. The end of the positioning shaft 9 away from the supporting positioning frame 8 is fixedly connected to the connecting support frame 15, and the outer ring of the connecting support frame 15 is fixedly connected to the transmission ring frame 16, and the transmission ring frame 16 is rotatably connected to the inner wall of the runner blade 11.

[0045] Specifically, the heat dissipation component includes a bearing 18, an impeller 19, a heat dissipation port 21 and a protective cover shell 22. The outer wall of the docking pipe 1 is fixedly connected to the bearing 18, the surface of the bearing 18 is fixedly connected to the impeller 19, the impeller 19 is arranged on the side of the stator winding 6 close to the ball valve 5, the middle of the flanges 2 on both sides is fixedly connected to the protective cover shell 22, the protective cover shell 22 is arranged on the outside of the annular protective cover 7, and the left and right ends of the protective cover shell 22 are symmetrically provided with heat dissipation ports 21, and the two heat dissipation ports 21 are respectively an air inlet and an exhaust port.

[0046] Specifically, the traction assembly includes a second permanent magnet 17 and a third permanent magnet 20. A slot is provided on the outer wall of the transmission ring frame 16. The second permanent magnet 17 is fixedly connected to the middle of the slot on the surface of the transmission ring frame 16 in a circular array. The third permanent magnet 20 is fixedly connected to the inner wall of the impeller 19. The magnetic poles of the second permanent magnet 17 and the third permanent magnet 20 that are close to each other are opposite.

[0047] Through the above structural design, when the runner blades 11 rotate, the positioning shaft 9 is driven to rotate through the fixed sleeve 10 in the middle. When the positioning shaft 9 rotates, the transmission ring frame 16 at the outer end is driven to rotate. Since the outer end of the transmission ring frame 16 is provided with a second permanent magnet 17 and the second permanent magnet 17 and the third permanent magnet 20 on the bottom surface of the impeller 19 have opposite magnetic poles, the impeller 19 and the outer wall of the docking pipe 1 can be driven to rotate through the third permanent magnet 20 while the second permanent magnet 17 rotates. The rotation of the impeller 19 causes the air in the middle of the docking pipe 1 and the protective cover shell 22 to flow, thereby effectively dissipating the heat of the stator winding 6.
