Abstract
The invention discloses an intelligent control valve with a filtering circuit. The intelligent control valve comprises a casing, a valve rod, a singlechip, a temperature sensor, the filtering circuit, an amplifying circuit and an A/D conversion circuit, wherein the casing is in a three-way structure, the valve rod is mounted in a through hole, a right-angled channel is arranged in the valve rod, the temperature sensor is mounted on the inner wall of the casing, the temperature sensor can collect a temperature signal in the casing and transmit the temperature signal which is processed by the amplifying circuit, the filtering circuit and the A/D conversion circuit to the singlechip; if the temperature signal received by the singlechip is approximately equal to the preset temperature, the valve rod is opened by a step motor mounted on the valve rod; and if the temperature signal received by the singlechip is different from the preset temperature, the valve rod is closed by the step motor, and fluid flows out through the right-angled channel of the valve rod. The water-saving purpose is accordingly realized.
