Description

Technical Field

[0001] This utility model belongs to the technical field of ball valve electric actuators, specifically relating to an angular stroke quick-opening electric actuator. Background Technology

[0002] In the process of modern industrial automation, rotary-stroke quick-opening electric actuators, as core components of valve control, are widely used in many fields such as petrochemicals, power, metallurgy, and environmental protection. Their performance directly affects the safety, stability, and efficiency of production processes. With the continuous expansion of industrial production scale and the increasing complexity of production environments, higher demands are placed on the response speed, control accuracy, and reliability of actuators. However, traditional rotary-stroke electric actuators have many problems in practical applications and are difficult to meet the needs of current industrial development.

[0003] Currently, in terms of equipment maintenance, the telescopic rods of existing isostatic pressing upper molds lack an effective automatic lubrication mechanism. Due to the frequent extension and retraction movements of the telescopic rods during the tile pressing process, after long-term use, the lack of timely and sufficient lubrication easily leads to severe wear and jamming. Once the telescopic rods malfunction, it will not only cause equipment downtime for repair and increase maintenance costs, but also seriously affect the production schedule and disrupt the company's production plan. Therefore, those skilled in the art have provided an angular stroke quick-opening electric actuator to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed angular stroke quick-opening electric actuator in order to solve the above problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a first mounting plate, a sealed outer shell is installed on the top of the first mounting plate, an oil storage tank is installed on the top of the first mounting plate, an electric telescopic rod is installed on the top of the oil storage tank, the output end of the electric telescopic rod passes through the top of the oil storage tank and is slidably connected to the inner side wall of the oil storage tank, a piston is fixedly installed on the output end of the electric telescopic rod and slidably connected to the inside of the oil storage tank, an oil inlet is opened on the side wall of the oil storage tank, a discharge valve is installed on the discharge end of the oil storage tank, and an oil nozzle is fixedly connected to the discharge end of the oil storage tank and located on the outer side wall of the discharge valve.

[0006] As a further optimization of this utility model, the oil inlet of the oil storage tank is connected to an oil delivery pipe, and the other end of the oil delivery pipe penetrates the side wall of the sealed outer shell.

[0007] As a further optimization of this utility model, a micro synchronous motor is fixedly installed on one side of the top center of the first mounting plate, and the output end of the micro synchronous motor passes through the bottom of the first mounting plate and is fixedly fitted with a drive gear.

[0008] As a further optimization of this utility model, a valve core is connected through the top of the first mounting plate, and a driven gear is fixedly sleeved at the bottom of the valve core and located at the bottom of the first mounting plate. The driven gear meshes with the side wall of the driving gear, and the bottom of the driven gear and the driving gear are rotatably connected to a second mounting plate.

[0009] As a further optimization of this utility model, the oil delivery pipe is located above the meshing end of the driven gear and the driving gear.

[0010] As a further optimization of this utility model, a relay electrically connected to a micro-synchronous motor is installed on the top of the first mounting plate, an electrical indicator switch electrically connected to the micro-synchronous motor is installed on the top of the first mounting plate, and a limit switch electrically connected to the electrical indicator switch is installed on the top of the first mounting plate. The valve core cooperates with the limit switch.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model adopts a composite transmission mode combining hydraulic and gear transmission. The electric telescopic rod drives the piston to move in the oil storage tank, and delivers hydraulic oil to the relevant parts through the oil pipeline to provide auxiliary power for valve opening. With the assistance of hydraulic power, when the micro synchronous motor drives the valve core to rotate through the active gear and the driven gear, it can effectively overcome the valve resistance torque.

[0013] 2. This utility model achieves precise angle control through the coordinated operation of limit switches, electrical indicator switches, and relays. When the valve core rotates, once it reaches the preset angle position, the valve core triggers the limit switch. The limit switch transmits a signal to the electrical indicator switch, which controls the relay to cut off the power supply to the micro synchronous motor in a timely manner, so that the valve core stops precisely at the target angle.

[0014] 3. This utility model separates the hydraulic system, transmission system, and control system into independent modules. For example, hydraulic components such as oil storage tanks and electric telescopic rods constitute an independent hydraulic module; micro synchronous motors, drive gears, and driven gears constitute a transmission module; and relays, electrical indicator switches, and limit switches constitute a control module. When a certain module fails, maintenance personnel can quickly locate and directly replace the corresponding module without having to disassemble the entire actuator on a large scale.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, this utility model includes a sealed outer shell 1, a first mounting plate 2, a second mounting plate 9, an oil storage tank 5, a micro-synchronous motor 4, and a valve core 11. The sealed outer shell 1 is installed on the top of the first mounting plate 2 to form a protective structure. The oil storage tank 5 is fixed on the top of the first mounting plate 2 and is equipped with an electric telescopic rod 12 and a piston 15 inside for conveying hydraulic oil. The micro-synchronous motor 4 drives the drive gear 14, which meshes with the driven gear 13. The driven gear 13 and the bottom of the drive gear 14 are connected to the second mounting plate 9, which drives the valve core 11 to rotate, thereby realizing the angular stroke control of the valve.

[0025] like Figures 1-6As shown, the oil storage tank 5 is installed on the top of the first mounting plate 2, and an electric telescopic rod 12 is installed on its top. The output end of the electric telescopic rod 12 passes through the top of the oil storage tank 5 and is fixedly connected to the piston 15. The piston 15 is slidably connected to the inner side wall of the oil storage tank 5. An oil inlet is opened on the side wall of the oil storage tank 5, and the oil inlet is connected to the oil supply pipe 7. The other end of the oil supply pipe 7 passes through the side wall of the sealed outer shell 1. A discharge valve 16 is installed at the discharge end of the oil storage tank 5, and an oil nozzle 8 is fixedly connected to the outer side wall of the discharge valve 16 at the discharge end.

[0026] like Figure 1 , Figure 4 As shown, a relay 3, an electrical indicator switch 6, and a limit switch 10 are installed on the top of the first mounting plate 2. The relay 3 is electrically connected to the micro-synchronous motor 4 and is used to control the start and stop of the motor. The electrical indicator switch 6 is electrically connected to the micro-synchronous motor 4 and displays the working status of the motor. The limit switch 10 is electrically connected to the electrical indicator switch 6 and cooperates with the valve core 11. When the valve core 11 rotates to the set position, it triggers the limit switch 10, and feeds back a signal through the electrical indicator switch 6 to control the operation of the motor, thereby achieving precise angle control of the valve.

[0027] It should be noted that when this utility model is in use: when the valve needs to be opened, the micro synchronous motor 4 is started by the relay 3. The micro synchronous motor 4 drives the drive gear 14 to rotate. The drive gear 14 meshes with the driven gear 13, driving the driven gear 13 and the valve core 11 to rotate synchronously. At the same time, the electric telescopic rod 12 is started. The output end of the electric telescopic rod 12 pushes the piston 15 to slide downward in the oil storage tank 5, so that the hydraulic oil in the oil storage tank 5 enters the oil supply pipe 7 through the oil supply port, and is delivered to the part that needs hydraulic power through the oil outlet 8 to assist the valve opening action.

[0028] During the rotation of the valve core 11, when it reaches the set angle position, the valve core 11 triggers the limit switch 10. The limit switch 10 transmits a signal to the electric indicator switch 6. The electric indicator switch 6 controls the relay 3 to stop the micro synchronous motor 4 from running, thereby precisely controlling the opening angle of the valve.

[0029] When the valve needs to be closed, the relay 3 controls the micro-synchronous motor 4 to reverse, driving the drive gear 14 and driven gear 13 to rotate in the opposite direction, so that the valve core 11 is reset. At the same time, the output end of the electric telescopic rod 12 drives the piston 15 to slide upward, stopping the delivery of hydraulic oil and completing the valve closing action.

[0030] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
