Description

Technical Field

[0001] The utility model relates to an electric valve, specifically an electric valve capable of flow regulation, belonging to the technical field of valves. Background Technique

[0002] The operating torque of an electric valve is larger than that of a common valve. The opening and closing speed of an electric valve can be adjusted. It has a simple structure and is easy to maintain. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. In the operation process of a traditional pneumatic valve, due to the buffering characteristics of the gas itself, it is not easy to be damaged due to jamming, but it must have a gas source, and its control system is also more complex than that of an electric valve. This type of valve should generally be installed horizontally in a pipeline.

[0003] After retrieval, an electric valve disclosed in a Chinese patent with the publication number CN217108413U relates to the technical field of electric valves. The utility model includes a valve body, and a sealing plate is arranged inside the valve body; a water outlet is opened on the sealing plate; wherein, a guiding hole is also opened inside the valve body; a valve rod assembly, the valve rod assembly includes a valve rod body; a sealing sleeve that is hermetically matched with the water outlet is fixed at one end of the valve rod body; an electric device, and the output end of the electric device is matched with the valve rod assembly. Through the functions of the valve body, the valve rod assembly and the electric device, the utility model solves the problems of general sealing effect and inconvenient operation and control of the existing electric valves.

[0004] Although the above patent can solve the problems of general sealing effect and inconvenient operation and control of the existing electric valves, the electric valve in the above patent does not have the function of automatically regulating the flow rate. When the electric valve is in use, it cannot automatically control the size of the flow rate; for this reason, we provide an electric valve capable of flow regulation to solve the above problems.

The lower surface of the waterproof box 201 is fixedly connected to the upper surface of the fixed column 1. The lower surface of the fixed column 1 is fixedly connected to the upper surface of the first connecting pipe 5. The first connecting pipe 5 and the waterproof box 201 are fixed together through the fixed column 1. The fixed column 1 plays a role in supporting and fixing, which can prevent the waterproof box 201 from tilting. One side inside the waterproof box 201 is fixedly connected to one end of a support plate 204. The upper surface of the support plate 204 is fixedly connected to the lower surface of a motor 203. The output shaft of the motor 203 is fixedly connected to the other end of a first rotating shaft 205. The middle of the other end of the first rotating shaft 205 is rotatably connected to the upper surface of the support plate 204. Through remote control, the data received by the remote receiver 202 is transmitted into the motor 203. The motor 203 drives the first rotating shaft 205 and a first straight gear 206 to rotate, realizing the automatic adjustment of the flow rate of the electric valve.

[0029] Please refer to Figure 3 , the lower surface inside the waterproof box 201 is rotatably connected to one end of the first rotating shaft 205. The middle of one end of the first rotating shaft 205 is fixedly connected to the middle of a first straight gear 206. The teeth on one side of the outer circumferential surface of the first straight gear 206 mesh with the teeth on one side of the outer circumferential surface of a second straight gear 207. The middle of the second straight gear 207 is fixedly connected to one end of a second rotating shaft 208. The outer circumferential surface of the second rotating shaft 208 is rotatably connected to the middle of the lower surface inside the waterproof box 201. The upper surface inside the waterproof box 201 is fixedly connected to the upper surface of the remote receiver 202. The second rotating shaft 208 drives a regulating valve 209 to rotate, which can adjust the flow rate of the electricity. The remotely transmitted data is received by the remote receiver 202, facilitating the control and adjustment by the staff. Through the remote antenna on the remote receiver 202, interference can be resisted to the greatest extent.

[0030] The other end of the second rotating shaft 208 is fixedly connected to the upper surface of the regulating valve 209. The outer circumferential surface of the regulating valve 209 is rotatably connected to the inside of a valve body 3. One side of the valve body 3 is fixedly connected to one side of the first connecting pipe 5. The other end of the first connecting pipe 5 is fixedly connected to one side of a first fixing plate 6. The other side of the first fixing plate 6 is fixedly connected to one side of a second fixing plate 9.

[0031] Please refer to Figure 4, the other side of the second fixing plate 9 is fixedly connected to one end of the second connecting pipe 10, the lower surface of the waterproof box 201 is fixedly connected to one end of the screw rod 12, and the other end of the screw rod 12 is slidably connected to the lower surface of the baffle plate 11. By fixing the second connecting pipe 10 on the first connecting pipe 5 through the second fixing plate 9, water can flow into the electric valve. Through the cooperation of the screw rod 12 and the baffle plate 11, the waterproof box 201 has stability and is prevented from shaking during long-term use. A second sealing ring 8 is arranged inside one side of the second fixing plate 9. The first fixing plate 6 and the second fixing plate 9 are fixed by bolts. The first sealing ring 7 and the second sealing ring 8 inside the first fixing plate 6 and the second fixing plate 9 can play a sealing role to prevent the electric valve from leaking.

[0032] Please refer to Figure 2 , a first sealing ring 7 is arranged inside the other side of the first fixing plate 6. The first connecting pipe 5 is fixed to the valve body 3, and the water flow adjusts through the first connecting pipe 5 and enters the valve body 3. The size of the water flow is controlled by the regulating valve 209 inside the valve body 3. The upper surface of the valve body 3 is fixedly connected to the lower surface of the fixed cylinder 4, and the upper surface of the fixed cylinder 4 is fixedly connected to the middle part of the lower surface of the waterproof box 201.

An adjusting hole 210 is arranged inside the regulating valve 209. When the flow rate of the electric valve needs to be adjusted, the motor 203 drives the first rotating shaft 205 and the first straight gear 206 to rotate, and the first straight gear 206 drives the second straight gear 207 to rotate synchronously, so that the second straight gear 207 drives the second rotating shaft 208 and the regulating valve 209 to rotate. By adjusting the regulating valve 209, the flow rate of the electric valve can be adjusted, and the size of the flow rate can be controlled through the adjusting hole 210 arranged on the regulating valve 209.

[0033] Working principle: The second connecting pipe 10 and the first connecting pipe 5 are fixed together by bolts. The first sealing ring 7 and the second sealing ring 8 are used to seal the gap between the first fixing plate 6 and the second fixing plate 9, playing a sealing role to prevent water from flowing out through the gap between the first fixing plate 6 and the second fixing plate 9. The motor 203 drives the first rotating shaft 205 and the first spur gear 206 to rotate, and the first spur gear 206 drives the second spur gear 207 to rotate. When the second spur gear 207 is driven by the first spur gear 206, it drives the second rotating shaft 208 to rotate. The second rotating shaft 208 drives the regulating valve 209 to adjust the flow rate of the electric valve. The flow rate and magnitude of the flow can be controlled through the regulating holes 210 provided on the regulating valve 209. It can also be remotely controlled. The staff transmits data remotely and receives it through the antenna, which is transmitted to the remote receiver 202, and then the motor 203 works through the connecting wire. The waterproof box 201 can be fixed by the fixing column 1, the screw 12 and the baffle 11 to prevent the waterproof box 201 from shaking. Under the action of the second rotating shaft 208, the regulating valve 209 can rotate inside the valve body 3, and the flow rate of the regulating valve 209 for the electric valve is adjusted, realizing the remote control of the flow rate of the regulating electric valve.
