Technical Field
[0001] This utility model relates to the field of electric valves, and in particular to a precision-adjustable electric valve. Background Technology
[0002] The main function of electric valves is to control the flow of media in pipelines. Electric valves use electrical energy to drive the actuator to realize the opening and closing and regulating actions of the valve, thereby controlling the opening and closing or regulating of the media in the pipeline. They are widely used in various industrial fields. The opening and closing speed of electric valves can be adjusted, and they have a simple structure and are easy to maintain.
[0003] Currently, most control valves require manual adjustment by operators during use. The speed of valve opening and closing is relatively limited, and the accuracy of flow control is somewhat limited, making it difficult to meet the work requirements of timely and precise flow regulation.
[0004] Therefore, since the aforementioned general control valves require manual adjustment, have limited opening and closing speeds, and have certain limitations in the accuracy of flow control, making it difficult to regulate flow in a timely and precise manner, a precise electric valve can be designed. Utility Model Content
[0005] To overcome the problems of ordinary control valves requiring manual adjustment, having limited opening and closing speeds, and having certain limitations in the accuracy of flow control, making it difficult to regulate flow in a timely and precise manner.
[0006] The technical solution of this utility model is as follows: a precision-adjustable electric valve includes an electric valve housing, an electric valve chamber on the left side inside the electric valve housing, an installation cavity on the upper side inside the electric valve housing, a valve core fixedly installed inside the electric valve chamber, a valve column inside the valve core, a transmission rod fixedly installed at the upper end of the valve column, the upper end of the transmission rod extending into the interior of the installation cavity, and a first spur gear fixedly installed on its surface, a drive motor fixedly installed inside the installation cavity on the side of the transmission rod, a second spur gear fixedly installed at the output end of the drive motor, a flow detection chamber on the right side inside the electric valve housing, a liquid flow sensor fixedly installed on the upper right side of the electric valve housing, and a hydraulic sensor fixedly installed on the upper side of the electric valve housing on the side of the liquid flow sensor.
[0007] Preferably, the drive motor can be precisely controlled by the control system, and the first and second spur gears can cooperate to achieve the transmission function. The flow rate can be controlled by the change of the connection area of the first and second through slots. The liquid flow sensor can monitor the liquid flow rate in real time, which can facilitate comparison and verification of the electric valve's flow regulation. The hydraulic sensor can detect the hydraulic pressure inside the pipeline system, which can facilitate the timely detection of abnormalities such as leakage. The valve core and valve column are tightly connected to ensure the accuracy of regulation. The sealing ring and wear-resistant ring can improve the sealing between the electric valve cavity and the mounting cavity.
[0008] Preferably, the valve core has a through groove 1 at both the left and right ends, and the valve column has a through groove 2 inside, with the through groove 1 and through groove 2 being compatible with each other.
[0009] Preferably, a sealing ring is fixedly installed on the upper end of the valve core on the side of the transmission rod, and a wear-resistant ring is fixedly installed on the surface of the transmission rod.
[0010] Preferably, the surface of the transmission rod is rotatably connected to the valve core, the transmission rod is rotatably connected to the electric valve housing, and the first spur gear is meshed with the second spur gear.
[0011] Preferably, the left end of the electric valve housing is fixedly connected to a valve inlet port, and the right end of the electric valve housing is fixedly connected to a valve outlet port, with the electric valve chamber and the flow detection chamber connected to each other.

[0014] The beneficial effects of this utility model are:
[0015] This precision-adjustable electric valve is driven by a control system that precisely controls the drive motor. The drive motor rotates the second spur gear, which in turn rotates the first spur gear, which in turn rotates the valve stem. The flow rate is controlled by the change in the connection area of the first and second through-slots, thus achieving automated flow regulation. This avoids errors caused by manual adjustment, improves the accuracy of valve flow regulation, and ensures fast opening and closing. A liquid flow sensor monitors the liquid flow rate after the electric valve's regulation in real time, facilitating comparison and verification of the electric valve's flow regulation, further ensuring the accuracy of regulation. At the same time, it allows for immediate detection of abnormal liquid flow data when the electric valve malfunctions, enabling timely repairs and improving the ease of use of the electric valve.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5 This utility model provides an embodiment: a precisely adjustable electric valve, including an electric valve housing 1, an electric valve chamber 2 opened on the left side inside the electric valve housing 1, an installation cavity 3 opened on the upper side inside the electric valve housing 1, a valve core 4 fixedly installed inside the electric valve chamber 2, a valve column 5 disposed inside the valve core 4, a transmission rod 6 fixedly installed on the upper end of the valve column 5, the upper end of the transmission rod 6 extending into the interior of the installation cavity 3, and a first spur gear 7 fixedly installed on its surface, a drive motor 8 fixedly installed on the side of the transmission rod 6 inside the installation cavity 3, a second spur gear 9 fixedly installed on the output end of the drive motor 8, a flow detection chamber 10 opened on the right side inside the electric valve housing 1, a liquid flow sensor 11 fixedly installed on the right side of the upper end of the electric valve housing 1, and a hydraulic sensor 12 fixedly installed on the side of the liquid flow sensor 11 at the upper end of the electric valve housing 1.
[0024] Please see Figures 1-4In this embodiment, through groove 13 is provided at both ends of the valve core 4, and through groove 2 14 is provided inside the valve column 5. Through groove 13 and through groove 2 14 are adapted to each other. A sealing ring 15 is fixedly installed on the upper end of the valve core 4 on the side of the transmission rod 6. A wear-resistant ring 16 is fixedly installed on the surface of the transmission rod 6. The surface of the transmission rod 6 is rotatably connected to the valve core 4. The transmission rod 6 is rotatably connected to the electric valve housing 1. The first spur gear 7 and the second spur gear 9 are meshed. The control system precisely controls the drive motor 8, which drives the second spur gear 9 to rotate, so that the first spur gear 7 drives the transmission rod 6 to rotate, further controlling the rotation of the valve column 5 inside the valve core 4. The flow rate is controlled by the change in the connection area of through groove 13 and through groove 2 14, thereby realizing automatic flow regulation, avoiding errors caused by manual adjustment, improving the accuracy of valve flow regulation and control, and ensuring the switching speed.
[0025] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, a valve inlet port 17 is fixedly connected to the left end of the electric valve housing 1, and a valve outlet port 18 is fixedly connected to the right end of the electric valve housing 1. The electric valve chamber 2 and the flow detection chamber 10 are interconnected. A flow detection rod 19 is fixedly connected to the lower end of the liquid flow sensor 11. A flow detection head 20 is fixedly connected to the lower end of the flow detection rod 19 inside the flow detection chamber 10. A hydraulic detection rod 21 is fixedly connected to the lower end of the hydraulic sensor 12. A hydraulic detection head 22 is fixedly connected to the lower end of the hydraulic sensor 21 inside the flow detection chamber 10. When the liquid passes through the flow regulation mechanism of the electric valve, it flows out from the flow detection chamber 10. The liquid flow sensor 11 monitors the liquid flow rate after the electric valve regulation in real time. At the same time, the hydraulic sensor 12 detects the hydraulic pressure inside the pipeline system, which facilitates comparison and verification of the electric valve's flow regulation, further ensuring the accuracy of the regulation. It also facilitates the immediate detection of abnormal liquid flow data when the electric valve malfunctions, allowing for timely maintenance and improving the ease of use of the electric valve.
[0026] During operation, the control system precisely controls the drive motor 8, which in turn drives the second spur gear 9 to rotate. This, in turn, drives the first spur gear 7 to rotate the transmission rod 6, further controlling the rotation of the valve spool 5 inside the valve core 4. The flow rate is controlled by the change in the connection area of the first through groove 13 and the second through groove 14, thus achieving automated flow regulation and avoiding errors caused by manual adjustment. After the liquid passes through the flow regulation mechanism of the electric valve, it flows out from the flow detection chamber 10. The liquid flow sensor 11 monitors the liquid flow rate after the electric valve regulation in real time, while the hydraulic sensor 12 detects the hydraulic pressure inside the pipeline system. This facilitates comparison and verification of the electric valve's flow regulation, further ensuring the accuracy of the regulation. It also allows for immediate detection of abnormal liquid flow data and timely maintenance when the electric valve malfunctions.
[0027] Through the above steps, the drive motor 8 drives the second spur gear 9 to rotate, which in turn drives the first spur gear 7 to rotate the valve stem 5. The flow rate is controlled by the change in the connection area of the first through slot 13 and the second through slot 14, thereby realizing automated flow regulation and avoiding errors caused by manual adjustment. This solves the problem that ordinary control valves require manual adjustment, have limited opening and closing speeds, and have certain limitations in the accuracy of flow control, making it difficult to regulate the flow rate in a timely and accurate manner.
