Abstract
The invention discloses an intelligent control valve comprising a shell body, a valve rod, a singlechip microcomputer, a temperature sensor, a filter circuit, an amplifying circuit and an A/D (Analog to Digital)switching circuit, wherein the shell body is a three-way structure; the valve rod is mounted in a through hole; a right-angle passage is arranged in the valve rod; the temperature sensor is arranged on the inner wall of the shell body; the temperature sensor collects a temperature signal in the shell body and transmits the temperature signal to the singlechip microcomputer through the amplifying circuit, the filter circuit and the A/D switching circuit; if the temperature signal received by the singlechip microcomputer is approximately same as a given temperature, the valve rod is opened through a step motor arranged at the valve rod; if the temperature signal received by the singlechip microcomputer is different from the given temperature, the valve rod is closed through the step motor so that fluids flow out through the right-angle passage of the valve rod to achieve the aim of saving water.
Description
Technical field
The present invention relates to valve field, particularly, relate to a kind of intelligent control valve.
Background technique
At present, water heater is widely used in the life, for safety, water heater all is installed in the outside, bathroom mostly, needs to connect very long water pipe, when needs are had a bath, often need to discharge water for a long time, just can reach suitable temperature, caused the waste of water resources.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of intelligent control valve, to realize water-saving advantage.
For achieving the above object, the technical solution used in the present invention is:
A kind of intelligent control valve, comprise housing, valve rod, single-chip microcomputer, temperature transducer, eliminator, amplification circuit and A/D change-over circuit, described housing is three-port structure, described valve rod is installed in the through hole, a right angle channel is set in the described valve rod, described temperature transducer is installed on the inner walls, temperature signal in the housing that described temperature transducer gathers, and with this temperature signal through amplification circuit, eliminator and A/D change-over circuit are transferred to single-chip microcomputer, the temperature signal that described single-chip microcomputer receives is approximately identical with the temperature of setting, then open valve rod by the stepper motor that is installed in valve rod, the temperature signal that described single-chip microcomputer receives is different from the temperature of setting, then by stepper motor that valve rod is closed, so that fluid is by the right angle channel outflow of valve rod.
Further, described temperature is all temperature signal and setting signal differs 5 ℃ approximately mutually.
The technological scheme of being invented, by set temperature sensor inside the control valve housing, control valve is installed in the outlet port of bathroom hot water, when water temperature reaches setting temperature, then hot water is discharged by water outlet, when water temperature does not reach setting temperature, then water is delivered to water heater again by pipeline and heats, realized water-saving purpose.
Below by drawings and Examples, technological scheme of the present invention is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the described intelligent control valve of the embodiment of the invention.
By reference to the accompanying drawings, reference character is as follows in the embodiment of the invention:
The 1-housing; The 2-valve rod; The 3-right angle channel.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of intelligent control valve, comprise housing, valve rod, single-chip microcomputer, temperature transducer, eliminator, amplification circuit and A/D change-over circuit, described housing is three-port structure, valve rod is installed in the through hole, a right angle channel is set in the valve rod, temperature transducer is installed on the inner walls, temperature signal in the housing that temperature transducer gathers, and with this temperature signal through amplification circuit, eliminator and A/D change-over circuit are transferred to single-chip microcomputer, the temperature signal that single-chip microcomputer receives is approximately identical with the temperature of setting, then open valve rod by the stepper motor that is installed in valve rod, the temperature signal that single-chip microcomputer receives is different from the temperature of setting, and is then by stepper motor that valve rod is closed, so that fluid is by the right angle channel outflow of valve rod.
Wherein, temperature is all temperature signal and setting signal differs 5 ℃ approximately mutually.When the temperature signal that receives when single-chip microcomputer approximates setting temperature greatly, between A mouth and B mouth together with so that water flows to the B mouth from the A mouth, when being less than or greater than setting temperature, then so that water is discharged by right angle channel, and flow to the C mouth from the A mouth.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment the present invention is had been described in detail, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. intelligent control valve, it is characterized in that, comprise housing, valve rod, single-chip microcomputer, temperature transducer, eliminator, amplification circuit and A/D change-over circuit, described housing is three-port structure, described valve rod is installed in the through hole, a right angle channel is set in the described valve rod, described temperature transducer is installed on the inner walls, temperature signal in the housing that described temperature transducer gathers, and with this temperature signal through amplification circuit, eliminator and A/D change-over circuit are transferred to single-chip microcomputer, the temperature signal that described single-chip microcomputer receives is approximately identical with the temperature of setting, then open valve rod by the stepper motor that is installed in valve rod, the temperature signal that described single-chip microcomputer receives is different from the temperature of setting, and is then by stepper motor that valve rod is closed, so that fluid is by the right angle channel outflow of valve rod.
2. intelligent control valve according to claim 1 is characterized in that, described temperature is all approximately mutually temperature signal and setting signal differs 5 ℃.
