All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] like Figure 1-7As shown in the figure, a manual adjustment and manual state recognition device for an electromagnetic control valve includes a manual controller 1, a valve stem 2, a circuit board 3, a base 4, a dial 5, and a baffle 6. A让位部7 is provided at the upper end of the base 4. The lower end of the manual controller 1 is installed in the让位部7. The upper end of the valve stem 2 is installed in the manual controller 1. The circuit board 3 is installed below the manual controller 1. The lower end of the valve stem 2 passes through the circuit board 3. The baffle 6 is installed above the circuit board 3. The dial 5 is installed between the baffle 6 and the circuit board 3. A push-button switch 8 is provided at the upper end of the circuit board 3. The lower end of the dial 5 abuts against the push-button switch 8. A spring 9 is provided between the manual controller 1 and the baffle 6. When the present utility model is in use, the valve can work according to an externally set signal. When manual operation is required, the manual controller 1 is pressed. At this time, the manual controller 1 abuts against the valve stem 2. The manual controller 1 and the baffle 6 are in a position where they are about to engage. The manual controller 1 is rotated. When rotating, the lower end of the manual controller 1 will push the upper end of the dial 5 outwards. At this time, the dial 5 will rotate along itself. The lower end of the dial 5 presses down the push-button switch 8, causing the push-button switch 8 to be triggered and transmitting a signal to the circuit board 3. After receiving the signal, the circuit board 3 determines that the valve is in the manual state. At this time, the externally given signal will be shielded and no longer work. On the contrary, rotating the manual controller 1 in the reverse direction can reset the manual controller 1, causing the dial 5 to move away from the circuit board 3. Under the action of the spring 9, the manual controller 1 and the baffle 6 are separated.

[0033] The present utility model can control the solenoid valve in two ways: manual and automatic, realizing the manual operation of the electromagnetic control valve and the automatic recognition of the manual operation state, which is convenient for use.

[0034] As Figure 1 、 4 、5 shown, in this embodiment, a convex platform 10 is provided in the middle of the baffle 6. The middle of the convex platform 10 is hollow. A clamping member 11 is provided on the side of the convex platform 10. A limiting member 12 is also provided on the baffle 6. The limiting member 12 is arranged in a "凵" shape. A clamping block 13 is provided on the inner wall of the limiting member 12.

[0035] As Figure 1 、 6 、7 shown, in this embodiment, a hook 14 is provided at the lower end of the dial 5. Two symmetrical wing members 15 are provided in the middle of the dial 5. Inner holes 16 are provided on the wing members 15. At least two inner holes 16 are provided on each wing member 15.

[0036] As Figure 1-3 shown, in this embodiment, an internal thread 23 is provided at the upper end inside the manual controller 1. An external thread 24 is provided at the upper end of the convex platform 10. The internal thread 23 and the external thread 24 are used in cooperation.

[0037] Specifically, the valve stem 2 passes through the boss 10, and the external thread 24 at the upper end of the boss 10 can be used to cooperate with the internal thread 23 of the hand-operated device 1. The upper end of the paddle 5 is used to cooperate with the limiting member 12. The hook 14 abuts against the push-button switch. The snap-fit ​​member 11 is used to snap with the lower end of the hand-operated device 1. When the hand-operated device 1 is pressed, the snap-fit ​​member 11 disengages from the lower end of the hand-operated device 1, and the hand-operated device 1 can be rotated.

[0038] Once the manual mode is detected, continuing to rotate the hand controller 1 will cause the internal thread 23 of the hand controller 1 to engage with the external thread 24 of the boss 10. The more the engagement occurs, the more the valve stem 2 moves down, which in turn pushes the valve body down further, allowing the valve opening to be manually controlled at any position. At this time, the manual mode can be continuously detected.

[0039] When the operator is installed in the default state, the upper end of the lever 5 is inside the limiting part 12 of the baffle 6, and the snap block 13 is connected to the inner hole 16 on the wing 15.

[0040] like Figure 1 As shown in this embodiment, in order to prevent the upper end of the paddle 5 from getting close to the baffle 6, a pad 17 is installed on the bottom plane of the baffle 6, and the upper end of the pad 17 abuts against the lower end of the spring 9.

[0041] like Figure 1 , 2 As shown in Figure 3, in this embodiment, a sealing ring 18 is provided between the hand-held device 1 and the base 4. The sealing ring 18 is made of elastic material. A groove 19 is provided on the outer side of the hand-held device 1. The sealing ring 18 is installed in the groove 19. The sealing ring 18 of this utility model is used to seal between the hand-held device 1 and the base 4 to prevent liquid from entering the base 4.

[0042] like Figure 3 As shown in this embodiment, in order to facilitate the rotation of the hand-held device 1, the upper end of the hand-held device 1 is provided with anti-slip texture 20.

[0043] like Figure 1 , 2 As shown, in this embodiment, the lower end of the hand-held device 1 is provided with a flat surface 21, and the inside of the hand-held device 1 is provided with an end face 22. The upper end of the spring 9 abuts against the end face 22. The flat surface 21 at the lower end of the hand-held device 1 is close to and slightly higher than the upper end of the lever 5 in the installation position, so that the hand-held device 1 can be disengaged from the snap-fit ​​member 11 of the baffle 6.

[0044] like Figure 3 As shown in this embodiment, the upper end of the hand controller 1 is provided with an indicator arrow 25. The indicator arrow 25 of this utility model is used to indicate the initial position of the hand controller 1. When it is not in the initial position, it indicates that the solenoid valve is in manual mode, and vice versa, it is in electric mode.

[0045] The working principle of this utility model:

[0046] By default, this invention is in automatic mode; the valve can operate according to externally set signals.

[0047] When manual operation is required, the hand-held device 1 is pressed down. At this time, the boss 10 is pressed against the probe of the LVDT sensor. The internal thread 23 of the hand-held device 1 and the external thread 24 of the boss 10 are about to engage. The plane 21 is flush with the plane of the lever 5 and basically fits. At the same time, the upper end of the snap-fit ​​11 is also higher than the upper surface of the upper limit groove 26 of the hand-held device 1. At this time, the limit groove 26 can no longer restrict the rotation of the hand-held device 1.

[0048] After pressing the hand controller 1, rotate the hand controller 1. At this time, the plane 21 rotates accordingly. When rotating, the circumference next to the plane 21 will push the lever 5 outward. At this time, the lever 5 will rotate along the inner hole 16, and the hook 14 will press down. The pressed hook 14 will trigger the push-button switch 8 and transmit the signal to the circuit board 3. After receiving the signal, the circuit board 3 determines that the valve is in manual mode. At this time, the externally given signal will be shielded and will no longer have an effect.

[0049] Continue rotating the hand-operated device 1. The internal thread 23 and the external thread 24 begin to engage. The hand-operated device 1 begins to press down on the LVDT sensor probe rod and then presses down on the armature valve rod, valve plate, and other components, causing the valve to open manually. This continues until the valve is fully open. After the internal thread 23 and the external thread 24 engage, the valve body can remain in any position due to the action of the threads. At this point, releasing the hand will not reset the valve.

[0050] Conversely, the valve is gradually closed manually until it is completely closed. When the top buckle of the snap-fit ​​11 is higher than the upper surface of the limit groove 26 and aligned with it, the plane 21 returns to the initial position and the push-button switch 8 resets. The circuit board 3 determines that the valve has returned to the automatic state. At this time, the hand controller 1 is released, and under the action of the spring 9, the hand controller 1 moves upward, and the top buckle of the snap-fit ​​11 snaps into the limit groove 26, returning to the initial state.

[0051] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
