Background technology
Solar heating engineering has obtained promotion and application widely.Constant temperature water supply is a kind of trend that hot water is used in life now.Yet solar heating engineering has that discharge is big, unstable properties, characteristics that the water temperature variable gradient is big.So most solar energy users usually can run into the water temperature instability, the time low problem when high.
At this problem, the water end (W.E.) of using at little caliber, usually adopt mechanical thermostatic valve to regulate water, specifically be to solve the water temperature instability problem by in the middle of hot water pipe, water-water jet being set, but often need repeatedly manual adjustments water-water jet in using, inconvenience on not only exist using, and adjustment process accommodative excess generation scald accident very easily repeatedly.
But the mechanical thermostatic valve of this kind is not suitable for using on the pipeline of the big caliber in the hot water engineering, so there is the problem of constant-temperature effluent difficulty on the pipeline of the big caliber of water system at present.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned prior art, a kind of thermostatically-controlled equipment that is applied in the solar heating engineering is provided, it can be mutually integrated with the hot water engineering pipeline, need not manual adjustment, can terminal be controlled in the ideal range with coolant-temperature gage by automatic control, use has more convenience and security, the generation of the scald accident that can effectively avoid.
The technical scheme taked of the utility model is to achieve these goals: a kind of thermostatically-controlled equipment, it is characterized in that: comprise PLC controller and the electric control valve by its control and temperature, pressure sensor, described electric control valve is installed in the meet of cold water pipe and hot-water line, and the water inlet of hot water of described electric control valve, cold water inlet and delivery port place are equipped with temperature, pressure sensor respectively.
The utility model is to control electric electric control valve opening angle by the PLC controller according to the temperature and pressure of hot water or cold water's water inlet of electric control valve, thereby realizes constant temperature water supply.Specifically the temperature and pressure signal of the hot and cold water pipeline water at the water-mixing temperature that collects and two ends is sent to the PLC controller by temperature, pressure sensor, by the opening angle and the velocity of rotation of PLC controller judgement back control electric control valve, thus the temperature of control terminal water outlet.So the utility model is applicable to the solar heating engineering system pipeline, have that flow is big, a stable performance, the small but excellent true advantage of water temperature variable gradient.
The beneficial effects of the utility model can be summarized as following 3 points:
1) compared to existing technology, the utility model is by PLC controller control motorized adjustment valve regulation water temperature, the problem of low and easy generation scald accident when high when root has solved that water temperature is unstable;
2) mixed water leaving water temperature compared to existing technology and temperature is set, thus the utility model is realized thermostatic control, the trouble that has needed repeatedly the manual adjustments water temperature to bring when having avoided water by opening angle and the velocity of rotation of adjusting electric control valve;
3) compared to existing technology, the utility model more is applicable to the solar heating engineering system, has that flow is big, a stable performance, the small but excellent true advantage of water temperature variable gradient.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of thermostatically-controlled equipment as shown in Figure 1 is applied in the solar heating engineering, specifically is by solar thermal collector 1 solar energy to be converted to heat energy, and the water in the heating storage tank 2 also is back to storage tank 2 with the water of heating.The hot water of storage tank 2 reaches hot water water intaking valve 4 by the road to electric control valve 6, and electric control valve 6 also links to each other with cold water water intaking valve 5 and cold water pipeline, and hot water and cold water mix water management through electric control valve 6 and flows out to shower 7, i.e. the required thermostatted water of user.
As shown in Figure 1, concrete described thermostatically-controlled equipment comprises: PLC controller 3 and the electric control valve 6 by its control and temperature, pressure sensor 6.1.Temperature, pressure sensor 6.1 are independent temperature and pressure sensors, when specifically implementing, also can use the temperature and pressure transmitter that is integrated in one.Wherein, electric control valve 6 is installed in the meet of cold water pipe and hot-water line, specifically between cold water water intaking valve 5 and hot water water intaking valve 4.The water inlet of hot water of electric control valve 6, cold water inlet and delivery port place are equipped with temperature, pressure sensor 6.1 respectively.Temperature, pressure sensor 6.1 are gathered the temperature and pressure of the hot water or cold water's who enters into electric control valve 6 temperature and pressure with the water outlet of level after electric control valve 6 mixes water respectively, and be transferred to PLC controller 3, control the opening angle and the velocity of rotation (as Fig. 2, Fig. 3 and shown in Figure 4) of electric control valve 6 again by PLC controller 3 output pulse signals, further control mixes the temperature of water, thereby reaches the effect of constant temperature water supply.
Need generally to guarantee that the pressure ratio of hot water or cold water's water inlet end is in 1: 2 scope.During use, retardance is arranged when considering temperature, pressure sensor 6.1 collecting temperatures, according to the mixed water leaving water temperature that collects with temperature is set compares, change the opening angle and the velocity of rotation of electric control valve 6, thereby change the size of inflow, allow water temperature variation slowly, make the temperature that collects more accurate, prevent electric control valve 6 misoperations.For example: compare water-mixing temperature and temperature is set, if the temperature difference is bigger, then the speed of rotation of PLC control electric control valve 6 is bigger; If the temperature difference is less, then the speed of rotation of PLC control electric control valve 6 is less.Can realize finely tuning the temperature of mixing water, reach the effect of constant temperature.
The utility model is easy to use and safe, more is applicable to the solar heating engineering system, has that flow is big, a stable performance, the small but excellent true advantage of water temperature variable gradient.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
