Abstract
A valve able to regulate the temp of output liquid features that it is connected to cold water source and hot water source, and the ratio of hot water to cold water is regulated to make the mixed water have the needed temp.
Description
Technical field
Present technique relates to the liquid of same substance, reaches the temperature output of setting after mixing under the situation of different temperatures.Hot and cold water by-pass cock as the electrical heating shower.
Background technology
Present electrical heating shower water outlet water temperature, water yield by-pass cock all adopt manual adjustments, its method is to open cold water switch when closing hot water outflow switch, and the hot water water yield is reduced increases the cold water water yield simultaneously, and leaving water temperature reduces, otherwise raise, its shortcoming is that accuracy is low.The advantage of the valve of scalable liquid output temperature is: simple in structure, cost is lower, material is general, easy and simple to handle.
Recognize also there be not the product identical at present with the present invention with some relevant units from market.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions: it is by the liquid nest of tubes, temperature sensor, the setting value input circuit, single-chip microcomputer, nest of tubes valve switch motor circuit, the nest of tubes valve driving machine, the nest of tubes valve switch, to the flow through sampled value of fluid temperature of each nest of tubes of temperature sensor passes to single-chip microcomputer, temperature when input requires liquid to flow out, import by setting value circuit, and signal passed to single-chip microcomputer, after the single-chip microcomputer computing signal is passed to nest of tubes valve driving machine circuit, this circuit control nest of tubes valve motor is regulated the nest of tubes valve switch." nest of tubes " forms fluid pipeline by the identical conduit of two or more bores, and each nest of tubes is carried the liquid with a kind of source.The temperature computation that " single-chip microcomputer " transmitted setting value input circuit and each electronics temperature detection sensor, single-chip microcomputer calculates (t establish-t is cold) and (t heat-t establishes) and (puts by heat Calculation formula Q suction=Q, so hot * of c*m (t heat-t the establishes)=cold * of c*m (t establish-t is cold), again according to m=n*s*r*T* ρ wherein c be the ratio of specific heat of liquid, n is flow of liquid single pipeline number in same nest of tubes, s is the cross-sectional area of the single pipeline in the nest of tubes, r is the flow velocity of liquid, T is the flowing time of liquid, ρ be density of liquid can obtain n heat/n cold=(t establish-t is cold)/(t heat-t establishes)), according to n heat/n cold=(t establishes-t is cold/(t heat-t establishes), by the nest of tubes valve driving machine position of each nest of tubes valve switch is adjusted.

Embodiment
When different temperatures liquid homogeneity with the situation of pressing under, the temperature that requires to flow out after the liquid mixing is " t establishes ", by setting value input circuit input single-chip microcomputer.Each single tube of nest of tubes valve outflow port is in one line, and the nest of tubes valve switch is N from the displacement of Guan Zhikai.If the first nest of tubes temperature " t heat ", the second nest of tubes temperature " t is cold ", through sensor temperature value is sent into single-chip microcomputer, single-chip microcomputer with all numerical value is calculated, according to n heat/n cold=(t establish-t is cold)/(t heat-t establishes), when (t establish-t is cold)＜(t heat-t establishes), then single-chip microcomputer output electric signal N-x1 is to the cold nest of tubes valve driving machine circuit of n, the cold nest of tubes valve driving machine of control n, the cold nest of tubes valve switch of n is opened to maximum, single-chip microcomputer output N/ (t heat-t establishes) * (t establish-t is cold)-x2 value (X2 is N/ (t heat-t establishes) * of last time (t establish-t is cold)), nest of tubes valve driving machine circuit to n heat, the nest of tubes valve driving machine of control n heat, the displacement that makes the nest of tubes valve switch of n heat is N/ (t heat-t establishes) * (t establish-t is cold)-x2; When (t heat-t establishes)＜(t establish-t is cold), single-chip microcomputer output signal N-x2 is to the nest of tubes valve driving machine circuit of n heat, the nest of tubes valve driving machine of control n heat is opened to maximum the nest of tubes valve switch of n heat, single-chip microcomputer output N/ (t establish-t is cold) * (t is warm, and t establishes)-X1 value (X1 is the N/ of last time (t establish-t is cold) * (t heat-t establishes)), it is N/ (t establish-t is cold) * (t heat-t establishes)-X1 that control n cold nest of tubes valve driving machine circuit, the control nest of tubes valve driving machine that n is cold again make the displacement of nest of tubes valve switch; When t establish=when t was warm, single-chip microcomputer output signal N-x2 was to the nest of tubes valve driving machine circuit of n heat, control nest of tubes valve driving machine, the nest of tubes valve switch of n heat is opened to maximum, output-x1 is to the cold nest of tubes valve driving machine circuit of n simultaneously, and control nest of tubes valve driving machine is closed the cold nest of tubes valve switch of n; When t establish=when t was cold, single-chip microcomputer output signal N-x1 controlled the nest of tubes valve driving machine again to the cold nest of tubes valve driving machine circuit of n, the cold valve switch of n is opened to maximum, output-x2 is to the nest of tubes valve driving machine circuit of n heat simultaneously, and control nest of tubes valve driving machine is closed the nest of tubes valve switch of n heat; When t establish＜t is cold, t is warm＜when t establishes, the unreasonable single-chip microcomputer output alarm signal set of explanation then.Main program block diagram such as Fig. 2.
