Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a folding wafer formula butterfly valve, including butterfly valve main part 1, square valve rod sleeve 2, adjustment handle 3, be equipped with valve rod 4 in the square valve rod sleeve 2, the circular sleeve 5 of upper end fixedly connected with of valve rod 4, square cavity 6 has been seted up in the circular sleeve 5, be equipped with square slider 7 in the square cavity 6, the little slider 8 of top right side fixedly connected with of square slider 7, adjustment handle 3's below is equipped with limiting plate 9, be equipped with first hinge 10 between limiting plate 9 and the square valve rod sleeve 2, be equipped with second hinge 11 between adjustment handle 3's right side and the little slider 8, adjustment handle 3's right-hand member is equipped with bolt 12.

In this embodiment, limiting plate 9 passes through first hinge 10 and square valve rod sleeve 2 swing joint, and the right side of adjusting handle 3 passes the center of limiting plate 9 and extends in the upper end of square cavity 6, and through second hinge 11 and little slider 8 swing joint, and bearing 13 and limiting plate 9 swing joint are passed through to the right side of adjusting handle 3, and the bolt 12 of adjusting handle 3 right-hand member passes limiting plate 9 and square valve rod sleeve 2's right side threaded connection.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
