Embodiment Construction
[0013] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0014] Such as figure 1 As shown, an intelligent control valve with a filter circuit includes a housing, a spool, a single-chip microcomputer, a temperature sensor, a filter circuit, an amplifier circuit and an A / D conversion circuit. The housing is a three-way structure, and the spool is installed on In a through hole, a right-angle channel is set in the valve column, and the temperature sensor is installed on the inner wall of the housing. The temperature sensor collects the temperature signal in the housing and transmits the temperature signal through the amplification circuit, filter circuit and A / D conversion circuit. For the single-chip microcomputer, the temp...

The invention discloses an intelligent control valve with a filter circuit. The intelligent control valve with the filter circuit comprises a shell, a valve rod, a single chip microcomputer, a temperature sensor, a filter, an amplification circuit and an A / D (analog / digital) conversion circuit, wherein the shell is in a tee joint structure; the valve rod is installed in a through hole; a rectangular channel is arranged in the valve rod; the temperature sensor is installed on the inner wall of the shell; the temperature sensor collects a temperature signal in the shell; the temperature signal is transmitted to the single chip microcomputer via the amplification circuit, the filter circuit and the A / D conversion circuit; if the temperature signal received by the single chip microcomputer is almost same with the set temperature, the valve rod is opened by a stepping motor installed on the valve rod; and if the temperature signal received by the single chip microcomputer is different from the set temperature, the valve rod is closed by the stepping motor, so that fluid flows out from the rectangular channel of the valve rod so as to realize a purpose of saving water.
Description
technical field [0001] The invention relates to the field of valves, in particular to an intelligent control valve with a filter circuit. Background technique [0002] At present, water heaters are widely used in daily life.
