DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0020] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0021] The following describes a double piston with stable flow provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0022] Combination Figure 1-3As shown, the utility model provides a double-piece piston with stable flow, including a fixed ring 1, one side of the fixed ring 1 is rotatably connected to a rotating rod 2, one end of the rotating rod 2 is fixedly connected to a first connecting piece 3, one side of the first connecting piece 3 is rotatably connected to a rotating ring 4, one end of the rotating ring 4 is rotatably connected to a second connecting piece 5, the interior of the rotating ring 4 is fixedly connected to a fixed rod 11, the outer wall of the fixed rod 11 is slidably connected to a rotating piece 12, the side wall of the rotating piece 12 is slidably connected to a positioning wheel 13, the middle part of the positioning wheel 13 is rotatably connected to a rotating shaft 14, and one end of the rotating shaft 14 is fixedly connected to the inner wall of the rotating ring 4;

[0023] A connecting ring 6 is fixedly connected to one side of the second connecting piece 5 , a fixing shaft 7 is fixedly connected to one side of the connecting ring 6 , and the first connecting pieces 3 are symmetrically arranged, and a driving shaft 10 is fixedly connected to a side wall of the first connecting piece 3 away from the rotating rod 2 .

[0024] In the first embodiment, the camshaft is driven to rotate by the driving shaft 10, and the rotating ring 4 is driven to move. The rotating ring 4 will form a swinging tendency when moving, and will drive the rotating plate 12 inside the rotating ring 4 to rotate during the rising and falling process. Then, the rotating plate 12 can be stably rotated with the assistance of the positioning wheel 13. During the rotation of the rotating plate 12, a rotation stabilizing force will be generated, and then the rotating ring 4 will remain stable when the rotating plate 12 moves, thereby ensuring that the piston can run smoothly, thereby reducing the increased wear caused by shaking or deviation, extending the service life of the piston, and ensuring stable flow.

[0025] The outer wall of the rotating ring 4 is slidably connected with a moving sheet 8, the top of the moving sheet 8 is fixedly connected with a piston body 9, a wear-resistant layer 15 is pressed on the surface of the piston body 9, a corrosion-resistant layer 16 is pressed on one side of the wear-resistant layer 15, and an anti-fatigue layer 17 is pressed on one side of the corrosion-resistant layer 16. The wear-resistant layer 15 is made of tungsten carbide, the corrosion-resistant layer 16 is made of nickel-based alloy, and the anti-fatigue layer 17 is made of silicon nitride.

[0026] In the second embodiment, the wear resistance of the piston body 9 can be increased by setting a wear-resistant layer 15, which can extend the service life of the surface of the piston body 9 and prevent the piston body 9 from deformation, thereby ensuring the stability of the flow rate and preventing leakage. At the same time, the corrosion-resistant layer 16 can improve the corrosion resistance of the piston body 9. When the liquid contacts the piston body 9, the piston body 9 will not be deformed due to corrosion. The anti-fatigue layer 17 ensures that the piston body 9 can maintain its own strength under long-term movement without breakage or deformation.

[0027] The working principle and use process of the utility model are as follows: when the parts on the first connecting plate 3 are driven to operate by the driving shaft 10, the rotating ring 4 on the camshaft can be driven to rotate, and when the rotating ring 4 rotates, the internal rotating plate 12 can be driven to move, and when the rotating plate 12 rotates, it can slide in contact with the positioning wheel 13, thereby ensuring that the rotating plate 12 rotates smoothly, and the rotating plate 12 can form a rotational balancing force when rotating, thereby allowing the rotating ring 4 to operate smoothly. When the rotating ring 4 operates smoothly, the moving plate 8 and the piston body 9 connected to the rotating ring 4 can operate smoothly, the wear-resistant layer 15 can increase the friction resistance of the piston body 9, the corrosion-resistant layer 16 can increase the corrosion resistance of the piston body 9, and the anti-fatigue layer 17 can increase the self-strength of the piston body 9.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
