[0023] Switch assembly 2 includes rotating handle 20 and rotating shaft 21, and the top of rotating shaft 21 is fixedly connected with rotating handle 20, and the top of connecting rod 32 is fixedly connected with threaded rod 22, and the outside of threaded rod 22 is connected with threaded sleeve 23, and the top of threaded sleeve 23 is provided with rotating bearing 24, and by rotating rotating handle 20, make rotating shaft 21 rotate, because threaded sleeve 23 is connected with main pipeline cover 13 through rotating bearing 24, so when rotating shaft 21 drives threaded sleeve 23 to rotate, make threaded rod 22 rise.
[0024] The multistage valve assembly 3 includes a multistage valve lower end cover 31, which is fixedly installed inside the throttle valve pipeline 10 at the end away from the rotating handle 20. A sealing gasket 36 is provided on the top of the multistage valve lower end cover 31, and a valve core 37 is movably installed on the top of the multistage valve lower end cover 31. A secondary sealing valve body 38 is movably connected inside the valve core 37. When the rotating handle 20 is rotated to raise the threaded rod 22, the threaded rod 22 will first drive the secondary sealing valve body 38 to rise, allowing liquid to flow out through the valve core 37. A primary sealing valve body 30 is movably installed inside the multistage valve lower end cover 31, and a connecting rod 32 is fixedly connected to the top of the primary sealing valve body 30. A valve cage 34 is movably connected to the outside of the connecting rod 32, and the connecting rod 34 is driven by the threaded rod 22.

[0025] The working principle of this multi-stage throttling valve will be explained in detail below.
[0026] like Figures 1-4 As shown, when using this multi-stage throttling valve, rotating the handle 20 causes the rotating shaft 21 to rotate. Since the threaded sleeve 23 is connected to the main pipe cover 13 via the rotating bearing 24, when the rotating shaft 21 drives the threaded sleeve 23 to rotate, the threaded rod 22 rises. When rotating the handle 20 causes the threaded rod 22 to rise, the threaded rod 22 first drives the secondary sealing valve body 38 to rise. The threaded rod 22 then drives the connecting rod 32 and the primary sealing valve body 30 to rise, allowing the liquid to pass through the lower end cover 31 of the multi-stage valve, enter the valve cage 34, and then enter the valve core 37 through the hole on the valve cage 34. The secondary sealing valve body 38 flows out from the outlet 11. The upper cover 33 of the multistage valve is connected to the throttle valve pipeline 10 through its external threads, so the sleeve 25 below the upper cover 33 of the multistage valve can be fixed.
