Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to figures 1, 2, 3: the thermoelectric refining high-temperature-resistant ferrite butterfly valve casting comprises a pipeline 1, wherein a valve rod 12 is arranged inside the pipeline 1, the top of the valve rod 12 penetrates through the top of the pipeline 1 and is in sliding connection with the pipeline, a key groove 9 is formed in the lower half portion of the outer side of the valve rod 12, and a butterfly plate 10 located inside the pipeline 1 is connected to the outer side of the valve rod 12 in a sliding mode through the key groove 9. The bottom of the pipeline 1 is provided with a bearing 11, and the bottom of the valve rod 12 is connected with the inner ring of the bearing 11 through a key groove 9 in a sliding manner. The top of the valve rod 12 is fixedly provided with a handle 7 positioned above the pipeline 1. The 1 outside of pipeline is equipped with

supports sleeve block

17, 1 inside pivot 13 that is located the butterfly plate 10 left side that is equipped with of pipeline, 13 tops of pivot rotate to be connected with and pass 1 tops of pipeline and support sleeve block 17 tops and rather than sliding connection's

first lifter

4, 13 outside arrays of pivot are equipped with vortex roller 18. The top of the first lifting rod 4 is rotatably connected with a rotating plate 5, a semicircular bulge 3 is fixedly arranged at the bottom of the rotating plate 5 in an annular fixed array mode, and a semicircular groove 6 matched with the semicircular bulge 3 is formed in the top of the supporting sleeve block 17. The outer side of the rotating plate 5 is fixedly provided with a first gear 2, the outer side of the valve rod 12 is fixedly provided with a second gear 8 which is meshed with the first gear 2 and has a width smaller than that of the first gear 2, and the second gear 8 can keep a meshed state with the first gear 2 when the first gear 2 moves up and down.
