Abstract
The present invention provides a hinged valve, comprising a handle, a valve body, a valve stem, a valve core, sealing rings, guide and a valve cover. The valve core is connected to the valve body by means of a hinge such that the valve core will be rotated around a rotation axis of the hinge. A locking hook and a positioning hole are provided on the valve stem. A positioning column, elastic buckles and guiding slot are provided on the guide. The positioning column is connected to the positioning hole of the valve stem and the guide is elastically assembled to the body of the valve stem under the effect of the elastic buckles of the guide, such that the guide and the valve stem will move synchronously without motion relative to each other. Rotating shafts and a guiding post are provided. The rotating shafts are rotatably connected to the connecting holes. The guiding post can move along the guiding slot in the guide such that the rotation of the valve stem will be transferred to the valve core via the slide by the guide and is converted into a rotation of the valve core around the rotation axis of the hinge so as to open or close the valve The valve of the present invention is structurally compact, easy to operate, open with a small torque, opened at a large angle, and allows for a large flow.
