Detailed ways

Referring to FIGS. 1 to 3 , in an embodiment of the present invention, a self-sealing energy-saving valve that can be monitored includes a valve body 1 . 2. The valve has a control effect on the pipeline. The upper end of the valve core 2 is equipped with a rotating rod 3, and the upper end of the rotating rod 3 is equipped with a rotating handle 4. Rotating the upper rotating handle 4 clockwise or counterclockwise can drive the rotating rod. 3 and the valve core 2 rotate synchronously to realize the opening or closing function of the valve. The upper surface of the valve core 2 is provided with a positioning groove 5, and the side wall of the rotating rod 3 is horizontally installed with a positioning rod 6. When tightening the valve device, The precise control of the valve can be achieved by observing the position where the positioning rod 6 rotates and the position of the positioning groove 5. When the rotating rod 3 rotates to a certain position, the valve is just closed. If it exceeds this position, it may cause internal damage. Threaded parts are damaged. If the valve is not screwed to this position, the valve may cause leakage in the pipeline and become dangerous.
