Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Fig. 1 to 3 show a first exemplary embodiment of the invention: the utility model provides a 9 formula manual positioning butterfly valves of flange, is including the installation pipeline 1 of taking the ring flange, be provided with valve plate 2 in the installation pipeline 1, the dwang 3 rotation connection of valve plate 2 through both sides is in the installation pipeline 1, its key lies in, wear out for at least one section of dwang 3 installation pipeline 1 and at its end-to-end connection have limiting plate 4, curved spacing groove 5 has been seted up on limiting plate 4 still be provided with spacing double-screw bolt 6 on the lateral wall of installation pipeline 1, spacing double-screw bolt 6 passes spacing groove 5 and threaded connection have with limiting plate 4 complex lock nut 7 1 still is connected with hand rocking arm 11 on the limiting plate.
Specifically, one end of the installation pipeline 1 is fixedly connected with the flange plate 9, and the other end of the installation pipeline is provided with a notch 10.
