Description
Technical field
The utility model relates to a kind of valve control device, and especially a kind of control device of central air-conditioning end belongs to the air conditioner controlling technology field.
Background technology
Understand according to the applicant, existing central air-conditioning terminal usually mainly by be placed near the fan coil the fan outlet, motor-driven valve and the temperature controller that is installed in liquid coolant (the being generally water) pipeline formed, the signal input part of temperature controller connects the temperature sensor that is placed in desired location, and its control output end connects the controlled end of motor-driven valve.
During operation, temperature controller compares according to design temperature Ts and detecting temperature Tm, in case Tm greater than Ts, temperature controller is just exported control signal and is opened motor-driven valve, otherwise then closes motor-driven valve.The open defect that the control mode of this traditional air-conditioning exists is, the break-make of motor-driven valve can't make indoor temperature be stabilized on the Ts, therefore brought comfortableness difference and energy waste problem, made the water conservancy balance of whole air-conditioning system be in the changeable and permanent state of mistake of pressure reduction often in addition.
The utility model content
The purpose of this utility model is: at the shortcoming that above prior art exists, propose a kind of central air-conditioning terminal intelligent dynamic constant-current control device that can make the controlled environment temperature stabilization in setting value, thereby save the energy, produce desirable comfort.
In order to reach above purpose, central air-conditioning terminal intelligent dynamic constant-current control device of the present utility model mainly by be placed near the fan coil the fan outlet, motor-driven valve and the temperature controller that is installed in liquid cold (or heat) matchmaker's pipeline formed, the signal input part of described temperature controller connects the temperature sensor that is placed in desired location, and its control output end connects the controlled end of motor-driven valve.Its improvements are: the thermodynamic-driven device is housed in the described motor-driven valve, described thermodynamic-driven device contains the electrothermal device of jointing temp controller control output end and is placed near the thermal expansion part of electrothermal device, and an end of described thermal expansion part is connected with the valve rod of motor-driven valve by link gear.
Like this, motor-driven valve no longer directly is controlled by the break-make control signal of temperature controller, but by the temperature of the output of temperature controller control electrothermal device, and then the swell increment of control thermal expansion part, by the open degree of linkage structure control valve rod, the result has thoroughly changed traditional break-make temperature control method, can be by the open degree of stepless regulated valve again, realize the accurate regulation and control of ambient temperature, reach the purpose of saving the energy, obtaining desirable air-conditioning effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
The central air-conditioning terminal intelligent dynamic constant-current control device of present embodiment as shown in Figure 1, fan coil 1 is placed near the air outlet of blower fan 2, two mouths of pipe connect respectively as the water inlet of liquid coolant and return pipe.Electric check valve 14 being housed in the inlet pipeline, being provided with flap 13 between its import and the outlet, fixedlys connected with the valve rod lower end that can move up and down in valve body in the middle part of this flap 13.Thermodynamic-driven device 4 is installed on valve body top, the electricity heating sheet 11 that contains jointing temp controller control output end in this thermodynamic-driven device, and the thermal expansion chamber 10 that is placed in electricity heating sheet top, filling paraffin 9 in the thermal expansion chamber 10, the top of paraffin leans against the lower end of extruding bar 8, the STATEMENT OF FEDERALLY SPONSORED 7 of cap shape is withstood in the upper end of extruding bar 8, and the outside of this STATEMENT OF FEDERALLY SPONSORED is with spring 6 by the spring tray 5 of upper end, and the bottom is connected with the upper end of valve rod 12.
Temperature controller 3 contains the temperature sensor that is placed in the precalculated position, the output of this sensor connects the signal input part AD/I0 mouth of single-chip microcomputer, one of control output end of this single-chip microcomputer connects controllable silicon by power circuit and photoelectric isolating circuit, and this controllable silicon is connected in the connecting circuit of electricity heating sheet coil and civil power.
During work, the temperature sensor that temperature controller carries (NTC thermistor, its resistance value and the temperature value relation of being inversely proportional to) is the collecting temperature signal automatically, the AD/I0 mouth of input single-chip microcomputer, and single-chip microcomputer compares indoor temperature Tm and the design temperature Ts that collects.According to comparative result, constantly adjust the silicon controlled output voltage, thereby change the caloric value of the electricity heating sheet of thermodynamic-driven device.Inflating medium paraffin in the thermodynamic-driven device expansion chamber is with the breathing of electric heating variations in temperature, drives to extrude masthead and go out or withdraw, and under the mating reaction of spring, the valve rod of electric check valve is corresponding to move up and down.When extraneous room temperature is higher, will drives flap to top offset, and cold (heat) matchmaker flow is strengthened, otherwise then drive flap, reduce flow to bottom offset.The final purpose that realizes with the accurate regulating and controlling temperature of open degree of control electric check valve.
In addition, in the temperature controller another control output end of single-chip microcomputer also by drive circuit and three relays machine third gear rotating speed control line of giving a dinner for a visitor from afar.Can further realize the regulation and control of steady temperature according to the difference control rotation speed of fan of indoor temperature and setting value like this.Usually open high speed winds during more than or equal to 5 ℃ when the temperature difference, less than 5 ℃ and open middling speed during more than or equal to 3 ℃, less than 3 ℃ and unlatching low speed during greater than design temperature.
In a word, present embodiment has following remarkable advantage: can be according to refrigeration (or heating) demand in each room, the air conditioner water flow of dynamic change is provided, reduce the quantity of the water pump of turning on the aircondition, the water conservancy balance of coming systems stabilisation with dynamic refrigeration (or heating) demand that satisfies the room to greatest extent and minimum flowed fluctuation as far as possible; Room temperature controller is poor according to design temperature Ts and room temperature Tm, adopts different wind speed, has both solved the problem of the quick temperature adjustment in room, helps reducing the interference of fan noise to environment again; Can have remarkable energy saving effect fully satisfying under the prerequisite of user to the requirement of comfort level.
