Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and more specifically, to a smart intelligent switch-type electric actuator. Background Technology

[0002] An on / off type electric actuator is a device driven by an electric motor that converts electrical energy into mechanical energy to achieve automated control. It is mainly used to control the opening and closing of equipment such as valves and dampers. In hazardous situations, automated actuators can reduce personnel injury. Certain special valves require emergency opening or closing under special circumstances; valve actuators can prevent further spread of danger while minimizing plant damage.

[0003] Existing technology, such as a utility model of an angular stroke electric actuator, authorized by publication number CN206054876U, allows for automatic disconnection of the motor power supply when the handwheel is in operation, even under energized conditions, enabling free operation of the handwheel under any circumstances.

[0004] Currently, there is a lack of an actuator that facilitates both automatic and manual operation, enabling the opening and closing of ball valves and the adjustment of valve size. In automatic operation, it would allow for precise control of the valve size. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide an intelligent on / off type electric actuator that facilitates both automatic and manual operation, enabling the opening and closing of ball valves and the adjustment of valve size. In automatic operation, it provides precise control of the valve size.

[0006] This utility model achieves its invention objective using the following technical solution:

[0007] A smart, intelligent switch-type electric actuator is characterized by comprising: a mounting housing, within which a partition is fixedly connected; an encoder, fixedly connected to the partition, with its input shaft passing through the partition and fixedly connected to a drive gear; a rotating cylinder, with a bearing connecting to the mounting housing and the drive gear fixedly connected; and a ball valve equipped with a switching shaft that matches the rotating cylinder. By employing an encoder, the ball valve's size can be precisely controlled, making it convenient to use. The switching shaft and rotating cylinder are detachable, allowing for manual rotation of the switching shaft to adjust the ball valve after disconnection.

[0008] As a further limitation of this technical solution, the partition is fixedly connected to the motor, the output shaft of the motor passes through the partition, and the output shaft of the motor is fixedly connected to the drive gear, which meshes with the power gear. By using a motor to drive the rotation of the rotating cylinder and using gear meshing, it is convenient to drive the rotating shaft to rotate, thereby realizing the opening, closing, and adjustment of the ball valve.

[0009] As a further limitation of this technical solution, the partition is fixedly connected to a slot, a rack is nested within the slot, the driving gear is fixedly connected to an auxiliary gear, and the auxiliary gear meshes with the rack. By employing rack and pinion meshing, the rack moves when the ball valve is switched on or off.

[0010] As a further limitation of this technical solution, the partition is fixedly connected to the mounting base, the mounting base is fixedly connected to the distance measuring sensor, and the distance measuring sensor is matched with the rack. The distance measuring sensor is used to measure the distance between itself and the rack, thereby achieving auxiliary measurement of the ball valve's size.

[0011] As a further limitation of this technical solution, the mounting shell is fixedly connected to symmetrical L-shaped mounting rods, each of which is provided with a through hole. The ball valve is fixedly connected to symmetrical mounting screws, which are matched with the symmetrical through holes. This facilitates the installation of the mounting shell, etc.

[0012] As a further limitation of this technical solution, the symmetrical mounting screws are respectively fixedly connected to the limiting circular plates, which facilitates the positioning of the L-mounting rod.

[0013] Compared with related technologies, the intelligent switch-type electric actuator provided by this utility model has the following beneficial effects:

[0014] (1) This device uses an encoder to precisely control the valve size and is easy to use;

[0015] (2) This device uses a gear and rack meshing mechanism and a distance sensor to measure the distance between the sensor and the rack to achieve auxiliary measurement of the valve size;

[0016] (3) This device uses an L-shaped mounting rod and a mounting screw to facilitate the installation and disassembly of the mounting shell. After disassembly, it is convenient to manually operate the switch shaft. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: A smart intelligent switch-type electric actuator includes: a mounting housing 1, with a partition 8 fixedly connected inside the mounting housing 1; an encoder 10, fixedly connected to the partition 8, with its input shaft passing through the partition 8 and fixedly connected to a power gear 14; a rotating shaft 7, with a bearing connected to the mounting housing 1 and the power gear 14 fixedly connected; and a ball valve 5, equipped with a switch shaft 4 that matches the rotating shaft 7. By using the encoder 10, the valve size of the ball valve 5 can be precisely controlled, making it convenient to use. The switch shaft 4 and the rotating shaft 7 are designed to be separable, allowing for manual rotation of the switch shaft 4 after disconnection to adjust the ball valve 5.

[0025] The encoder 10 is model E6B2-CWZ1X.

[0026] The partition 8 is fixedly connected to the motor 9, and the output shaft of the motor 9 passes through the partition 8. The output shaft of the motor 9 is fixedly connected to the drive gear 15, and the drive gear 15 meshes with the power gear 14. By using the motor 9 to drive the rotation of the rotating shaft cylinder 7 through gear meshing, the ball valve 5 can be opened, closed, and adjusted.

[0027] The motor 9 is model JGB37-3625.

[0028] The mounting housing 1 is fixedly connected to symmetrical L-shaped mounting rods 6, each of which has a through hole. The ball valve 5 is fixedly connected to symmetrical mounting screws 3, which are matched with the symmetrical through holes. This facilitates the installation of the mounting housing 1, etc.

[0029] The symmetrical mounting screws 3 are respectively fixedly connected to the limiting circular plates 2, which facilitates the positioning of the L mounting rod 6.

[0030] The working principle of the intelligent switch-type electric actuator provided by this utility model is as follows:

[0031] During installation, align the through hole of the L-mounting rod 6 with the mounting screw 3, align the rotating shaft cylinder 7 with the switch shaft 4, and fit the rotating shaft cylinder 7 around the switch shaft 4. The mounting screw 3 passes through the L-mounting rod 6 so that the L-mounting rod 6 contacts the limiting circular plate 2. Tighten the nut onto the mounting screw 3 to achieve stable installation of the L-mounting rod 6.

[0032] When ball valve 5 needs to be opened, control motor 9 rotates, motor 9 drives drive gear 15 to rotate, drive gear 15 drives power gear 14 to rotate, power gear 14 drives rotating shaft cylinder 7 to rotate, rotating shaft cylinder 7 drives switch shaft 4 to rotate, power gear 14 drives input shaft of encoder 10 to rotate, so that encoder 10 measures the rotation angle of switch shaft 4 and controls the valve size of ball valve 5.

[0033] Example 2: This example further elaborates on Example 1. The partition 8 is fixedly connected to the slot 11, and a rack 17 is nested inside the slot 11. The drive gear 15 is fixedly connected to the auxiliary gear 16, and the auxiliary gear 16 meshes with the rack 17. By using the gear and rack meshing, the rack 17 moves when the ball valve 5 is opened or closed.

[0034] The partition 8 is fixedly connected to the mounting base 12, and the mounting base 12 is fixedly connected to the distance measuring sensor 13, which is matched with the rack 17. The distance measuring sensor 13 is used to measure the distance between itself and the rack 17, thereby enabling auxiliary measurement of the valve size of the ball valve 5.

[0035] The model number of the ranging sensor 13 is E3Z-D61-BG.

[0036] The working principle of the intelligent switch-type electric actuator provided by this utility model is as follows:

[0037] When the drive gear 14 rotates, it drives the auxiliary gear 16 to rotate. The auxiliary gear 16 drives the rack 17 to move. The distance sensor 13 measures the movement distance of the rack 17 and calculates the number of rotations of the auxiliary gear 16. The rotation angle of the switch shaft 4 is measured by the diameter ratio of the auxiliary gear 16 to the drive gear 15 and the tooth ratio of the drive gear 14 to the drive gear 15.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
