[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1 (as attached) Figures 1 to 5 The root valve with automatic adjustment function shown includes a root valve body 1. An adjustment mechanism 2 is provided on the upper surface of the root valve body 1. The adjustment mechanism 2 includes an adjustment handle 21, which is rotatably connected to the root valve body 1. A vertical rod 22 is fixedly connected to the outer arc surface of the adjustment handle 21. The rotatable connection between the adjustment handle 21 and the root valve body 1 facilitates manual adjustment of the root valve by the operator. The vertical rod 22 is fixedly connected to its outer arc surface. Rotating the handle moves the vertical rod 22. A gear 23 is fixedly connected to the lower surface of the vertical rod 22. Gear 23 is rotatably connected to the upper surface of the root valve body 1. When the adjustment handle 21 rotates, the vertical rod 22 rotates accordingly, thereby driving the connected gear 23 to rotate. A gear 24 is rotatably connected to the upper surface of the root valve body 1, also rotatably connected to the upper surface of the root valve body 1. Gear 24 cooperates with gear 23, rotating under the drive of gear 23 to achieve transmission function. Yes, gear 24 meshes with gear 23. A motor 25 is fixedly connected to the upper surface of the root valve body 1. The output shaft of the motor 25 is fixedly connected to gear 24. A compensation pipe 26 is slidably connected to the front surface of the root valve body 1. The compensation pipe 26 is fixedly connected to the connector 27. A sealing plug 28 is fixedly connected to the outer arc surface of the compensation pipe 26. A ring 29 is fixedly connected to the inner surface of the connector 27 and slidably connected to the front surface of the root valve body 1. During the operation of the root valve, it can slide on the front surface of the root valve body 1 according to actual needs. The sealing plug 28 is fixedly connected to its outer arc surface, serving a sealing function to prevent media leakage. Simultaneously, the compensation pipe 26 is fixedly connected to the connector 27, which connects and cooperates with other components.
[0022] Specifically: When it is necessary to adjust the root valve body 1, the motor 25 can be started. The output shaft of the motor 25 drives the gear 24 to rotate, and the gear 24 then drives the gear 23 meshing with it to rotate, thus achieving automatic adjustment of the root valve. When it is necessary to install the root valve body 1, the compensating tube 26 can be moved inside the root valve body 1 by pulling the connecting piece 27, thereby driving the compensating tube 26 to extend or shorten the root valve body 1.
[0023] Example 2: Based on Example 1, the solution in Example 1 is further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details: In a preferred embodiment, a limiting mechanism 3 is provided on the front surface of the root valve body 1. The limiting mechanism 3 includes a fixed rod 31, and a tapered rod 32 passes through the left surface of the fixed rod 31 and is slidably connected to the tapered rod 32. This sliding connection allows the tapered rod 32 to move flexibly on the fixed rod 31 according to actual working needs, thereby meeting the adjustment requirements of the limiting position under different working conditions. One end of the tapered rod 32 is fixedly connected to the spring 33, and the other end of the fixed rod 31 is fixedly connected to the spring 33.
[0024] In a preferred embodiment, a limiting rod 34 is fixedly connected to the outer arc surface of the compensating tube 26. The left surface of the limiting rod 34 has slots 35 arranged in a linear array. These slots 35 are slidably connected to the tapered rod 32. This linear array design ensures the regularity and consistency of the slots 35's distribution. The size and shape of the slots 35 are carefully designed to enable a sliding connection with the tapered rod 32. This sliding connection provides a certain degree of freedom and movement for the relevant mechanical structure or device during operation, ensuring that the components can move relative to each other while also achieving precise position limitation and motion control through the cooperation of the limiting rod 34, the slots 35, and the tapered rod 32.
[0025] In a preferred embodiment, a pin 36 passes through the right surface of the fixing rod 31 and is slidably connected to the pin 36. The pin 36 passes through the tapered rod 32 and is slidably connected to the tapered rod 32. This design allows the pin 36 to move flexibly between the fixing rod 31 and the tapered rod 32. When it is necessary to adjust or fix the relative position of the two, the pin 36 can achieve the function of locking or unlocking by sliding.
[0026] The working process of this utility model is as follows: First, when the connector 27 drives the compensation tube 26 to move forward, the pin 36 needs to be pulled backward to disengage from the conical rod 32. Then, the connector 27 is pulled outward or inward, which will drive the compensation tube 26 to move. When the compensation tube 26 moves, it will drive the limiting rod 34 to move. The limiting rod 34 drives the slot 35 to move, which will squeeze the curved surface of the conical rod 32. After being squeezed, the conical rod 32 will move to the left and stretch the spring 33. When the connector 27 stops moving, the conical rod 32 will spring into the slot 35 through the spring 33. After the pin 36 is reinserted into the conical rod 32, the compensation tube 26 will be limited. The above is the working principle of the root valve with automatic adjustment function.
