[0032] Please refer to Figure 1-Figure 3 As shown, the present application provides a regulating valve handle, which is used to open or close the valve body, can realize fast and accurate opening and closing of the valve, and the valve handle structure and assembly process are simple. The regulating valve handle includes a handle body 2 and a steering connection assembly 3, wherein the handle body 2 can be arranged on the valve body, and a limiting groove is provided on the handle body 2; the steering connection assembly 3 includes a connecting seat 31 and a driving member 1, the connecting seat 31 is arranged at the output end of the driving member 1, and at least one limiting protrusion is provided on the connecting seat 31, and the limiting protrusion can be limited in the limiting groove along the direction of opening or closing the valve body; the driving member 1 can drive the handle body 2 to rotate along the direction of opening or closing the valve body. By using the limiting protrusion and the limiting groove to limit each other, the steering connection assembly 3 and the handle body 2 can be interlocked and rotated in the direction of opening or closing the valve body, and the handle body 2 and the steering connection assembly 3 can be easily docked, reducing the assembly steps; the output end of the driving member 1 is connected to the steering connection assembly 3, and the driving member 1 is used to drive the handle body 2 to automatically rotate in the direction of opening or closing the valve body, which can accurately control the rotation angle of the steering connection assembly 3 and ensure that the valve body stays at the required opening and closing position, thereby achieving precise flow control. Through the control of the automated system, the operating efficiency is greatly improved and the need for manual operation is reduced.

[0033] In order to enhance the connection strength and stability between the handle body 2 and the steering connection assembly 3, as shown in FIG. Figure 2 As shown, in some embodiments, a first limiting protrusion 32 and a second limiting protrusion 33 are symmetrically arranged at the center position of the connecting seat 31, and a first limiting groove 21 and a second limiting groove 22 are respectively arranged on the handle body 2, wherein the first limiting groove 21 is configured to limit the first limiting protrusion 32, and the second limiting groove 22 is configured to limit the second limiting protrusion 33; by arranging the first limiting protrusion 32 and the second limiting protrusion 33, the contact area between the handle body 2 and the steering connection assembly 3 is increased, thereby significantly enhancing the overall connection strength, and by arranging two groups of symmetrically arranged limiting protrusions and limiting grooves, the force can be shared with each other, thereby improving the uniform force of the structure and reducing the stress concentration problem caused by single-point force.

[0034] To further simplify the installation process, Figure 3As shown, in some embodiments, the first limiting groove 21 penetrates the handle body 2 along the depth direction of the first limiting groove 21, the first end of the first limiting groove 21 is connected to the second limiting groove 22, and the second end of the first limiting groove 21 penetrates the edge of the handle body 2 along the length direction of the first limiting groove 21. During the installation process of the handle body 2 and the steering connection assembly 3, since the second end of the first limiting groove 21 penetrates the handle body 2 along the length direction of the first limiting groove 21 and its first end is connected to the second limiting groove 22, the steering connection assembly 3 can be connected to the handle body 2 by sliding, and the second limiting protrusion 33 is limited by the first limiting groove 21 sliding into the second limiting groove 22, and then the first limiting protrusion 32 slides into the first limiting groove 21, the first limiting protrusion 32 can abut against the side wall of the first limiting groove 21, and the second limiting protrusion 33 abuts against the side wall of the second limiting groove 22; since the steering connection assembly 3 cannot continue to slide after encountering resistance, the operator can judge that the steering connection assembly 3 is installed in place. The operator can judge the installation status of the steering connection assembly 3 and the handle body 2 only based on the tactile feedback of whether the steering connection assembly 3 can continue to slide, making the installation process more simple and efficient. Further, the size of the first limiting protrusion 32 is larger than the size of the second limiting protrusion 33, and the foolproof design of the first limiting protrusion 32 and the second limiting protrusion 33, which is one large and one small, effectively prevents installation errors. It can be understood that the sizes of the first limiting groove 21 and the second limiting groove 22 correspond to the first limiting protrusion 32 and the second limiting protrusion 33 respectively; due to the different sizes of each group of limiting protrusions and limiting grooves, it is ensured that the installation can be completed only in the correct direction and position, avoiding mis-installation. Optionally, the larger first limiting protrusion 32 is set at a position on the connecting seat 31 close to the outer edge of the handle body 2, so that the larger first limiting protrusion 32 is used as the main force point, which can withstand greater stress, improve the strength of the steering connection assembly 3 when rotating, and extend its service life.

[0035] like Figure 1As shown, in some embodiments, the steering connection assembly 3 further includes a locking member 34, a positioning hole 35 is provided on the connection seat 31, and the positioning hole 35 is located between the first limiting protrusion 32 and the second limiting protrusion 33. The first end of the locking member 34 passes through the first limiting groove 21 and is connected to the positioning hole 35, and the second end of the locking member 34 abuts against the side of the first limiting groove 21 away from the second limiting groove 22 to lock the handle body 2 and the connection seat 31. Through the locking member 34, the handle body 2 and the steering connection assembly 3 are locked perpendicular to the direction of opening or closing of the valve body. Through double locking, the connection strength and stability of the two are further improved, and the connection can be maintained firmly when the regulating valve handle is subjected to vibration or impact, reducing the risk of loosening or separation of the two. Among them, the positioning hole 35 can be set at the center of the connection seat 31, which helps to evenly distribute the stress of the regulating valve handle device. Furthermore, a limiting platform 23 is provided at the edge of the first limiting groove 21 away from the second limiting groove 22, and the locking member 34 can be limited to the limiting platform 23, wherein the limiting platform 23 is an L-shaped step, and the second end of the locking member 34 can abut against the L-shaped step, and the limiting platform 23 provides a fixed position for the locking member 34 to prevent the locking member 34 from loosening and slipping due to shaking during the rotation of the valve body; making the assembly process simpler and more accurate, reducing the need for precise alignment, and improving assembly efficiency. Furthermore, the steering connection assembly 3 also includes a gasket, which is arranged between the locking member 34 and the limiting platform 23, wherein the gasket can provide a buffering effect, and when the valve is opened or closed, it can effectively prevent the contact between the locking member 34 and the limiting platform 23 from being worn, protect the limiting platform 23 and the locking member 34, and extend the service life of the two. It should be noted that the gasket can be a metal gasket or a rubber gasket, which is not specifically limited here, as long as it can play a buffering role. Furthermore, the locking member 34 can be, but is not limited to, a bolt or a limit pin, wherein when the locking member 34 is a bolt, the positioning hole 35 on the connecting seat 31 is a threaded hole so that the bolt can be connected to the positioning hole 35 .

[0036] It should be noted that the driving element 1 can be, but is not limited to, an electric driving element, an electromagnetic driving element, or a stepping motor driving element.

[0037] The present application also provides an automatic valve, comprising a valve body and a regulating valve handle in any of the above embodiments, wherein the handle body 2 is provided with a mounting hole 24, and the handle body 2 is mounted on the valve body through the mounting hole 24. The valve body is driven by the regulating valve handle, and the first limiting groove 21, the second limiting groove 22, the first limiting protrusion 32 and the second limiting protrusion 33 are mutually limited, so that the handle body 2 and the steering connection assembly 3 can be easily docked, reducing the assembly steps; the driving member 1 can accurately control the rotation angle of the steering connection assembly 3 to ensure that the valve body stays at the required opening and closing position, thereby achieving precise flow control, and through the control of the automated system, the operating efficiency is greatly improved, and the need for manual operation is reduced.
