With reference to Fig. 2, a kind of Control arrangement for heating system 200 that is used for that the utility model embodiment provides comprises temperature transducer 21, controller 22 and electrically-controlled valve 23;
The control control end of controller 22 respectively with electrically-controlled valve 23 in heat responsive device on the two poles of the earth be connected;
Described electrically-controlled valve 23 is arranged on the thermal medium transmission channel, is used to control heat medium flow to radiator.
The utility model embodiment provides, and a kind of working principle that is used for Control arrangement for heating system 200 is as follows:
After configuring temperature value as the duct thermostat in certain room, when indoor true temperature is lower than set temperature value, temperature transducer 21 does not output signal to controller 22, there is not operating voltage between two electrodes of the PTC temperature-sensitive rod 7 in the electrically-controlled valve, PTC temperature-sensitive rod 7 does not generate heat, and memory alloy spring 6 is in original contraction state; Because the elastic-restoring force effect of reset spring 2, force magnet ring 3, the push rod 11 of its upper end to be in high position (position as shown in the drawing), magnet ring 3 passes through magnetic coupling interaction, force the magnetic post 13 in the spool 4 in the valve core housing 5 to be in the high position, the piston of spool 4 its lower ends of pulling leaves the water outlet in the valve body, valve is in the state of opening, and heat medium flow is to heat dissipating pipe or radiator;
When room temperature raises gradually, when reaching the setting temperature indicated value of room temperature regulator, temperature transducer 21 outputs signal to controller 22, controller 22 is added to PTC temperature-sensitive rod 7 in the electrically-controlled valve by lead with operating voltage, PTC temperature-sensitive rod 7 is again rapidly with heat transfer memory alloy spring 6, when the temperature on the memory alloy spring 6 arrives deformation temperature, memory alloy spring 6 deformation is at once expanded, promoting push rod 11 moves downward, push rod 11 promotes magnet ring 3 again and moves downward, magnet ring 3 is in compression reset spring 2, and by magnetic coupling, the magnetic post 13 that promotes in the spool 4 moves downward, the piston that magnetic post 13 drives spool 4 and lower end moves downward, force piston to block the interior water outlet of valve body, valve is turn-offed, thermal medium stops to flow to heat dissipating pipe or radiator;
When room temperature is reduced to the set temperature value of regulator when following gradually, the regulator power cutoff, PTC temperature-sensitive rod 7 in the electrically-controlled valve loses power supply and stops heating, because memory alloy spring is the one way memory alloy, remember condition is the high temperature elongation state, memory alloy spring 6 temperature are reduced to the deformation temperature value when following, and memory alloy spring 6 is softening, at reset spring effect compound compression state next time.Under the effect of reset spring 2, spool 4 drives piston and leaves water outlet in the valve, and heat medium flow is to radiator or heat dissipating pipe; Heating system can maintain range of set temperature with room temperature like this.
The electrically-controlled valve that the utility model provides, by operating voltage being added to the PTC temperature-sensitive rod 7 in the electrically-controlled valve, and rapidly with heat transfer memory alloy spring 6, deformation is expanded when the temperature on the memory alloy spring 6 arrives deformation temperature, promote push rod 11 motions, by magnetic coupling, drive spool 4 and piston motion, thereby control valve turn-offs.Owing to adopted PTC heat responsive device, the electrically-controlled valve that the utility model provides to have that energy consumption is low, the characteristic of stable work in work, can realize the long-range sensitive control of electrically-controlled valve.
The above is a preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.All any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all be included in the protection domain of the present utility model.
