[0002] A valve body handwheel is a wheel-shaped device on a valve used for manual operation. It is typically used to adjust the valve's opening and closing position and allows control of fluid flow by manually rotating the handwheel. The handwheel is usually connected to the valve stem; turning the handwheel moves the stem up and down, thus opening or closing the valve. In industrial and mechanical applications, the design and material of the valve body handwheel can vary depending on the environment and media requirements. Common materials include cast iron, stainless steel, and plastic. The size and shape of the handwheel can also differ to accommodate different valve types and operational needs. When using a valve body handwheel, operators must prioritize safety and ensure that operation does not damage the valve or piping system.

[0003] The existing valve body handwheel may be accidentally touched by non-professionals when installed on the valve, which may cause abnormal valve opening and closing and thus affect the safety of pipeline transportation. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Please see Figure 1-4The present invention provides the following embodiment: The present invention is implemented as follows: A valve body handwheel with anti-non-professional operation function includes a valve seat 1, a valve stem 2, and a handwheel disc 3. A cross bracket 4 is fixed on the inner side wall of the handwheel disc 3. A mounting seat 5 is fixed in the middle of the cross bracket 4. A limit pin 6 is inserted into the side wall of the mounting seat 5. A slot 7 is formed on the side wall of the mounting seat 5 for the limit pin 6 to be inserted. A mounting groove 8 is formed at the bottom end of the mounting seat 5 for the valve stem 2 to rotate. The slot 7 penetrates the side wall of the mounting seat 5 and communicates with the mounting groove 8. A rotating platform 11 is fixed at the top end of the valve stem 2. The valve stem 2 and the rotating platform 11 are both made of stainless steel and are fixedly connected to form an integral structure. The external dimensions of the rotating platform 11 are adapted to the internal dimensions of the mounting groove 8, improving the stability of the rotation of the rotating platform 11. A slot 12 is formed on the side wall of the rotating platform 11 for the limit pin 6 to be inserted. The slot 12 penetrates the side wall of the rotating platform 11. The slots 7 and 12... Located on the same horizontal plane, the limit pin 6 is convenient for insertion and positioning. The limit pin 6 is made of low carbon steel and is T-shaped. The external dimensions of the limit pin 6 are adapted to the internal dimensions of the first hole 7 and the second hole 12. One end of the limit pin 6 is inserted into the inside of the first hole 7 and the second hole 12 in sequence, thereby realizing the connection between the rotary table 11 and the mounting seat 5. When the operator rotates the handwheel 3, it can drive the cross bracket 4, the mounting seat 5, the limit pin 6, the rotary table 11 and the valve stem 2 to rotate synchronously, thereby changing the height of the valve stem 2 and the plug 9 inserted into the valve seat 1, thereby realizing the opening and closing operation of the valve seat 1. When the operator has finished adjusting, pulling up the end of the limit pin 6 can remove the limit pin 6 and release the limitation on the mounting seat 5 and the rotary table 11. When non-professionals rotate the handwheel 3, the mounting seat 5 is rotatably connected to the outer surface of the rotary table 11, thereby avoiding disturbance to the valve stem 2, thus improving the safety of the valve body during use.

[0022] The outer surface of the valve stem 2 is provided with a threaded groove 10 for threaded connection of the valve seat 1. Both ends of the valve seat 1 are fixed with flanges, which improves the stability of the valve stem 2 installation. The bottom end of the valve stem 2 is fixed with a plug 9, which is slidably connected inside the valve seat 1. When the plug 9 moves up and down inside the valve seat 1, it can adjust the size of the valve body opening, thereby facilitating the valve body to control the flow. A sealing ring 13 is snapped onto the outer surface of the plug 9. The sealing ring 13 is made of rubber and is in the form of a ring, which improves the sealing performance of the plug 9 installation.

[0023] The bottom end of the cross bracket 4 is fixed with a clamp 14. The bottom end of the cross bracket 4 near the clamp 14 is provided with a sliding groove 15 for the limit pin 6 to be inserted. The external dimensions of the limit pin 6 are adapted to the internal dimensions of the sliding groove 15, which improves the convenience of storing and hiding the limit pin 6.

[0024] Working Principle: This valve body handwheel, designed to prevent operation by unauthorized personnel, is used by the operator who first rotates the handwheel 3 to align slot 7 and slot 12. Then, one end of the limiting pin 6 is sequentially inserted into slots 7 and 12, thus connecting the rotating platform 11 and the mounting base 5. Rotating the handwheel 3 at this time causes the cross bracket 4, mounting base 5, limiting pin 6, rotating platform 11, and valve stem 2 to rotate synchronously, changing the height of the valve stem 2 and the plug 9 inserted into the valve seat 1, thereby enabling the opening and closing of the valve seat 1. When the operator has completed the adjustment, pulling the end of the limiting pin 6 removes it, releasing the restriction on the mounting base 5 and rotating platform 11. When unauthorized personnel rotate the handwheel 3, the mounting base 5 rotates onto the outer surface of the rotating platform 11, preventing disturbance to the valve stem 2 and improving the safety of the valve body during use.

[0025] Next, the limiting pin 6 is inserted into the inside of the clamp 14 and the slide groove 15 in sequence, thereby improving the convenience of storing and hiding the limiting pin 6.
