The utility model discloses an electric adjusting valve which comprises a valve body and a pressure-proof rubber pipe located in the valve body and further comprises an electric push rod and a valve locator. Columns perpendicular to the pressure-proof rubber pipe are arranged on the left side and the right side of the pressure-proof rubber pipe, an upper press plate and a lower press plate which are arranged on the upper side and the lower side of the pressure-proof rubber pipe are connected onto the columns, the upper press plate is movably connected with the columns and can slide along the columns, and the lower press plate is fixedly connected with the columns. The valve body is fixed on the columns, the electric push rod is connected above the upper press plate, and the valve locator is in linkage with the upper press plate. The electric push rod is adopted as a power source and drives the upper press plate to act under a command of the locator to achieve the aim of adjusting the openness of the rubber pipe and controlling fluid flow. The electric push rod is high in location accuracy and high in self locking capability. The upper press plate serving as an execution mechanism is connected onto the columns through a sliding sleeve and is smooth in action and easy to maintain. Bosses subjected to galvanizing are arranged on the sides of the upper press plate and the lower press plate in contact with the pressure-proof rubber pipe, damage to the pressure-proof rubber pipe is reduced, and the service life is prolonged.
