Description

Technical Field

[0001] The utility model relates to the technical field of valve control devices, in particular to a valve angle automatic display and feedback structure. Background Art

[0002] Water valve electric actuators can remotely open and close water valves, and when linked to a computer, can irrigate the land at a fixed time and location. However, since the valve is located inside the water pipe, it is generally impossible to visually observe the valve's open and closed state or the opening angle.

[0003] A Chinese utility model patent, with authorization publication number CN201866381U, discloses a device called an "electric valve actuator with an indicator device." The utility model comprises an outer housing, a motor, and an actuator. The motor and actuator are housed within the outer housing. The motor serves as the actuator's drive source. The actuator comprises a worm shaft and a worm gear shaft. The worm gear shaft is sleeved with a worm gear that is linked to the worm shaft. One end of the worm gear shaft is linked to an external valve to control the opening and closing of the valve and the opening angle. The other end of the worm gear shaft is provided with an indicator device. The indicator device comprises an indicator disc and a pointer. The indicator disc is fixed to the end face of the worm gear shaft and has scale lines corresponding to the opening and closing and opening angles of the valve. The pointer is fixed to the outer housing. The outer housing is provided with an observation window for observing the indicator device. The user can observe the position of the indicator disc after the pointer rotates through the observation window, accurately and intuitively grasping the opening and closing state and opening angle of the valve.

[0045] The working principle of this utility model is:

[0046] like Figure 1-8 As shown, the motor 1 is powered on and electrically connected to the control circuit module 3. The control end sends a signal to control the motor 1 to start, the motor output end 11 begins to rotate, the first gear 21 also rotates accordingly, and engages the second gear 22 to rotate accordingly. The second gear 22 is fixedly connected to the valve connecting shaft 5, the valve connecting shaft 5 begins to rotate, and opens the valve plate connected to the valve connecting shaft 5 (taking a butterfly valve or a ball valve as an example, not shown in the figure).

[0047] As the indicator shaft 7 rotates, the third gear 23, located at its center, also rotates, causing the fourth gear 24, meshed with the third gear 23, to rotate. A magnet 241 with N and N poles is embedded in the fourth gear 24. As magnet 241 rotates, the direction of its magnetic field changes. The angle detection chip 31 uses Hall effect technology to accurately detect the rotation angle of the fourth gear 24.

[0048] When the motor 1 or the control circuit module 3 fails, use a hexagonal wrench to hold the hexagonal hole at the upper end of the manual operating rod 25 to rotate the manual operating rod 25, driving the fifth gear 26 fixed to the lower end of the manual operating rod 25 to rotate. The fifth gear 26 rotates and is transmitted to the second gear 22 through the meshing gear set. The valve connecting shaft 5 is rotated by the second gear 22, and the valve opening angle can be manually controlled. During manual operation, the position indicator 4 and the fourth gear 24 also rotate accordingly, and the real-time valve opening angle can also be observed and displayed.
