[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to elaborate on the present application in detail.

[0027] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0028] As Figures 1 to 4 shown, this application provides a metering scale valve positioning device, which includes a valve gate 1, a valve body 2, a pulley group 3 and a reinforcing rib 4. The valve gate 1 is used to carry goods and prevent the flow of the medium, can form a good seal, prevent the leakage of the medium, and has a basic cut-off function. The valve body 2 is located at the lower end of the valve gate 1 and is symmetrically arranged in two groups. The valve body 2 is used to support the valve gate. Four groups of pulley groups 3 are provided, which are respectively located outside the two groups of valve bodies 2. The pulley group 3 includes a mounting frame 31 and a pulley body 32 rotatably connected to the mounting frame 31. A first connection hole 34 is opened on one side of the mounting frame 31, and a second connection hole 21 is opened on one side of the valve body 2. A bolt 33 is provided on one side of the mounting frame 31. By passing the bolt 33 through the first connection hole 34 and the second connection hole 21 and tightening it with a nut to the threaded part of the bolt 33, the pulley group 3 is installed in this way. By fixing the pulley group 3 on the valve body 2, it plays a guiding role and reduces the jamming problem during operation. The reinforcing rib 4 is welded on the inner sides of the valve gate 1 and the valve body 2 and is trapezoidal. The reinforcing rib 4 is used to improve the overall strength and rigidity of the valve gate 1.

[0029] In this embodiment, by welding the trapezoidal reinforcing rib 4 on the inner sides of the valve gate 1 and the valve body 2, firstly, in terms of enhancing the structural strength, the valve may bear great pressure and the impact force generated by the flow of the medium during operation. The reinforcing rib 4 effectively prevents the valve from deforming or cracking under high pressure, large flow or frequent operation conditions by increasing the mechanical strength and rigidity of the valve body 2, and ensures the stability and safety of the valve during operation; secondly, it reduces the vibration influence during the working process. The valve may vibrate when the medium passes through. The symmetrically arranged reinforcing ribs 4 can suppress the vibration to a certain extent and reduce the fatigue damage caused by vibration; thirdly, it effectively improves the mechanical properties. The design of the reinforcing rib 4 helps to disperse the stress concentration points and reduce the risk of local failure of the material in the high-stress area, thereby improving the overall load-bearing capacity and service life of the valve;

[0030] After installing guiding pulley sets 3 on both sides of the valve body 2 respectively, the pulley sets 3 are used to keep the valve body 2 positioned and the bearing sliding smoothly. First, the pulley sets 3 are used to precisely guide and restrict the valve body 2, which can effectively prevent the valve gate 1 from swaying or moving loosely left and right during the opening and closing process, greatly improving the stability of the valve operation. Secondly, the introduction of the pulley sets 3 can replace part of the sliding friction with rolling friction. This design significantly reduces the operating resistance of the valve gate 1 during the opening and closing process, making the opening and closing actions of the valve smoother and more labor-saving, and improving the operating performance of the valve. In addition, due to the reduction of the operating resistance and the precise control of the movement trajectory of the valve gate 1, the mechanical wear of the valve is reduced, thereby reducing the failure rate caused by wear and extending the service life of the valve. For the weighing scale that relies on the stable operation of the valve, this improvement can ensure its stable operation throughout the working process, improving the weighing accuracy and the overall working quality and efficiency of the equipment.

[0031] In summary: Through the two key technical elements of the pulley sets 3 and the reinforcing ribs 4, this application greatly optimizes the operating performance of the valve gate 1. The use of the pulley sets 3 ensures smooth and low-resistance rotation of the valve gate 1 during the action process, while the design of the reinforcing ribs 4 provides strong internal support, thus ensuring that the raft gate 1 can open and close flexibly and stably, not only improving the working efficiency of the equipment, but also significantly extending the service life.

[0032] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, various changes and modifications can be made to this application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
