More Information
Summary:The valve comprises a valve body and a valve rod, the bottom end of the valve rod is rotationally connected with a valve ring, the top end of the valve rod is connected with a counting display screen, the top end of one side, close to the valve rod, of an upper sealing piece is connected with a first clamping seat, the other end of the first clamping seat is hinged to a second clamping seat, and the bottom end of the valve ring is connected with a third clamping seat. According to the utility model, the rotation of the valve rod drives the valve ring to perform arc-shaped rotation around the first clamping seat on one side, the size of the circular circulation space is increased step by step in a mode of obliquely moving the valve ring, and the circular circulation space is more uniform. The adjusting range is expanded, meanwhile, contact impact between the straight face of fluid and the valve ring is avoided, then the impact influence is weakened, meanwhile, in the process that the valve ring rotates around
