The multi-way ball valve is a three-way ball valve 1, and the three passages of the three-way ball valve 1 are respectively connected to the first pipeline assembly 2, the second pipeline assembly 4 and the third pipeline assembly 6 through flanges; the connection between the three-way ball valve 1 and the first pipeline assembly 2, the second pipeline assembly 4 and the third pipeline assembly 6 is provided with a sealing gasket 3 to ensure its sealing performance.

[0025] like Figure 2 As shown, the steering control assembly 5 includes an oil cylinder 11 and a supporting structure. The oil cylinder 11 is connected to any pipeline through the supporting structure. The push rod part of the oil cylinder is connected to the valve stem through a hinge mechanism, and the push rod part reciprocates along the rotation direction of the valve stem. The supporting structure includes a bottom plate 15, a vertical plate 10, a first ear plate 9 and a second ear plate 10; the bottom plate 15 is connected to the flange where the third pipeline assembly 6 is located through bolts 7 and nuts 8, the vertical plate 10 is connected to the bottom plate 15, the first ear plate 9 and the second ear plate 10 are arranged on both sides of the vertical plate 10, and a sleeve is welded to the periphery of the oil cylinder 11. The two sides of the sleeve are respectively provided with second pins 25, and the two second pins 25 are respectively connected to the first ear plate 9 and the second ear plate 10. This supporting structure can be fixed on the flange surface connected to the three-way ball valve 1 and any pipe assembly.

[0026] like Figure 2-4As shown, the hinge mechanism includes a first pin shaft 13 and a split pin 12. The push rod portion and the valve stem 14 are hingedly connected through the first pin shaft 13. Split pins 12 are respectively provided at both ends of the first pin shaft 13. The split pins 12 are used to prevent the first pin shaft 13 from falling off. A sealing plate 23 is fixed to the first ear plate 9 through a first screw 24. The sealing plate 23 is used to clamp the second pin shaft 25.
