| description | The utility model relates to the field of stop valves, and discloses a stop valve anti-rotation structure which comprises a valve cover, a fixing frame is fixedly connected to the middle position of the top end of the valve cover, a valve rod penetrating through the fixing frame is rotatably connected to the top end of the valve cover, and a rotating handle is fixedly connected to the top end of the valve rod. Fixing cylinders are movably connected to the two sides of the top end of the fixing frame, positioning rods are movably connected to the top ends of the fixing cylinders, and positioning blocks are fixedly connected to the top ends of the positioning rods. According to the stop valve anti-rotation structure, the positioning rod is pulled to drive the positioning block to move to a proper position, the adjusting block moves to be clamped into a proper adjusting hole through the elastic force of the adjusting spring, the positioning rod is limited and fixed after sliding, and then the overall height of t |
