This utility model will realize by the following technical solutions: it includes controller, automatic valve, converter, water Pump, the first pressure transducer, the second pressure transducer, the 3rd pressure transducer, the secondary network of temperature sensor composition supply water control Device processed and heat exchanger, the heat exchange station of dirt separator composition, described control device is put down by secondary network water supply controlling organization and pipe network Weighing apparatus controlling organization composition.

Described secondary network water supply controlling organization is to take in the import and export of heat exchanger and the dirt separator of heat exchange station to increase respectively If the 4th pressure transducer, the 5th pressure transducer, the 6th pressure transducer, the 7th pressure transducer, and by described 4th pressure Force transducer, the 5th pressure transducer, the 6th pressure transducer, the 7th pressure transducer receive signal, and to be respectively connected to controller defeated Enter end, and outfan connects alarm.

Described pipe network balance control mechanism be arrange between secondary network service water outlet to dwelling building unit feed pipe right The multiple static balancing valves answered, and the import and export of described static balancing valve are connected to same flow equilibristat input, even Constitute with smart mobile phone.

The beneficial effects of the utility model: owing to taking secondary network water supply controlling organization and pipe network balance control mechanism Organically combine, heat exchanger and dirt separator pressure changing can not only be observed at any time, find that blocking is carried out in time in good time Safeguard thus reduce resistance of pipe system and realize energy-conservation, and resident family's heat can be improved all according to resident family's traffic demand regulation flow equilibrium Even property, to reach the purpose of hydraulic equilibrium by minimum discharge, and runs ginseng through smart mobile phone by human-computer interactive control in strange land Number, makes region pipe network reach balanced heating, energy-efficient operation.And there is inventive concept novelty, reasonable in design, workability The advantages such as energy is reliable, convenient operation and control, applicable industry popularization.

Accompanying drawing explanation

Fig. 1 is district heating energy-saving control device overall structure schematic diagram.

Detailed description of the invention

District heating energy-saving control device shown in Fig. 1, is by controller 3, automatic valve 5, frequency conversion at existing heat exchange station Device 6, control water pump 7 and automatic valve 5 imports and exports second, third set pressure transducer 81,82 and secondary network supplies water out On the basis of the secondary network water supply control apparatus that mouth the first pressure transducer 8, temperature sensor 9 form, the novel joint of one of design Device can be controlled.Described energy-saving control device is mainly by setting respectively in the import and export of heat exchanger 4 and dirt separator 13 adapter Put the four, the 5th pressure transducer 83,84 and the six, the 7th pressure transducers 85,86, and described four, the 5th pressure are passed The pressure signal that sensor 83,84 and the six, the 7th pressure transducer 85,86 receives is respectively connected to controller 3 input, is controlling Device 3 outfan connects alarm 14.And collectively form secondary network water supply controlling organization 1 with existing secondary network water supply control apparatus. Meanwhile, also secondary network service water outlet between each dwelling building unit feed pipe 12,121,122,123 respectively correspondence set Put static balancing valve 11,111,112,113, then it is same that described static balancing valve 11,111,112,113 is imported and exported parallel access Flow equilibrium instrument 10 input, forms pipe network balance control mechanism 2 together with smart mobile phone.

Use of the present utility model, first controls journey by controller 3, automatic valve 5, flow equilibrium instrument 10 and smart mobile phone Sequence carries out preset with setup parameter, then diagnoses pipe network situation, opens working power, this reality under normal circumstances at pipe network Start working with novel.Under the control of controller 3, converter 6 supplies water for secondary pipe network by the frequency run set, water pump 7. By the first pressure transducer 8, secondary network service water outlet pressure signal being sent into controller 3, via controller 3 carries out data process, and Comparing with the parameter set, when pressure is more than setup parameter, its output controls converter 6 and reduces frequency, and water pump 7 is relative Slow rotation.Then control converter 6 when pressure is less than setup parameter and improve frequency and the relatively rapid rotation of water pump 7 meets pipe Net water requirements.And the temperature signal that secondary network service water outlet temperature sensor 9 gathers is admitted to a secondary net water supply automatic valve (i.e. backwater side one secondary net water supply valve) 5.This automatic valve 5 and second, third pressure transducer 81 imported and exported set by two ends, 82 collectively constitute differential pressure flowmeter, and himself is with controller, can be according to the surveyed actual temperature of temperature sensor 9 through internal calculation It is automatically adjusted the aperture of automatic valve 5.Institute's measuring pressure and temperature signal can be sent directly into controller 3 by described automatic valve 5, Controller 3 regulates a secondary net heat with automatic valve 5 after receiving temperature sensor 9 signal, reduces heat consumption.Controller 3 and frequency conversion Device 6 controls water pump 7 and runs, saves energy.Controller 3 also receives heat exchanger 4 and dirt separator 13 both sides the four, the 5th pressure sensing The pressure signal of device 83,84 and the six, the 7th pressure transducer 85,86, according to institute's measuring pressure situation post analysis monitoring heat exchanger 4 Changing with dirt separator 13 internal drag, as the power that is hampered increases internal blocking, controller 3 exports control signal alarm 14 and Times Alert.Guarantee that region pipe network is properly functioning.Ginseng is run also by wireless communication mode in scene by controller 3 and flow equilibrium instrument 10 Number reaches in technical staff's smart mobile phone, and smart mobile phone is given by after APP computing according to parameters such as site pressure, temperature, flows The aperture of each static balancing valve 11,111,112,113, by human-computer interactive control, presses traffic demand allocation unit resident family one by one Flow, improves each resident family room temperature uniformity, realizes hydraulic equilibrium with minimum discharge, reaches balanced heating energy saving, consumption reduction and high efficiency and runs Purpose.
