Below, will specifically introduce first embodiment of calorimeter metered valve of the present invention in conjunction with Figure of description 1.
Valve body 1 is by control module 2 controls, here, control module 2 is formed by the control circuit that comprises single-chip microcomputer with by the motor that control circuit drove, building control circuit with single-chip microcomputer, to control motor be the known means of those skilled in the art, here no longer describe in detail, specifically can be with reference to the CY-TM type temperature-sensing valve of producing by logical sincere beneficial company in Beijing.The output terminal of motor is connected with valve body, drives the rotation of spool by the rotation of motor, thus the folding degree of application valve body 1.
Here, heat exchanger 3 typically is heating installation, can be hot-water heating, also can be that hot air heating or oil are warm.Fluid (water or gas) is flowed into by the inlet of valve body, is flowed out by the outlet of valve body, flows into via the inlet of pipeline from heat exchanger, and flows out from the outlet of heat exchanger.Thereby, by heat exchanger, reach the purpose of exchange heat, the house is heated.
Be respectively equipped with a temperature sensor 41, temperature sensor 42 at the inlet end of valve body 1 and the endpiece of interchanger, be used to measure the temperature of the fluid that is passed through, and measured temperature is fed back to control module 2.Here, though temperature sensor 41 is located at the inlet end of valve body 1 among Fig. 1, but in actual applications, can also as required temperature sensor 41 be arranged on the endpiece of valve body 1, be arranged on before the inlet end of interchanger 3 as long as guarantee temperature sensor 41.
Q＝C*ΔT*G (1)
Wherein, Q is the heat that heat or heat exchanger consumed of interchanger output; C is the specific heat of fluid; Δ T is that the temperature value by temperature sensor 41, temperature sensor 42 feedbacks calculates the fluid temperature that interchanger 3 backs descend of flowing through; G is the quality of fluid of heat exchanger of flowing through.
The occurrence of G can calculate by formula (2).
G＝ρ*ΔI*Δt (2)
Wherein ρ is the proportion of fluid; Δ I is flow velocity or the flow definite according to the folding of valve body 1; Δ t is a heating time.
The advantage of the embodiment of Fig. 1 is that composed component is less, and is easy to implement, and its shortcoming is that flow Δ I is the respective value that the folding degree according to valve body 1 obtains, and is not measured value, therefore, has inevitable error between empirical value and the actual value.
Figure 2 shows that the second embodiment of the present invention.
The difference part of calorimeter metered valve shown in Figure 2 and calorimeter metered valve shown in Figure 1 is calculating or the measuring method of G.Among Fig. 2, be provided with flowmeter 5 at the inlet end of heat exchanger 3.Certainly, flowmeter 5 also can be arranged on the endpiece of heat exchanger 3.
