Description

Intelligent control valve

Technical field

The utility model relates to a kind of intelligent control valve that is used for building and heating metering system, is specifically related to a kind of temperature survey, radio communication and embedded system utilized and comes the intelligent control valve that building and heating is controlled automatically and measured.

Background technology

Energy prices surging impels people to carry out energy-conservation activity in every field.In the building and heating field, for realizing energy-saving and emission-reduction, heating charging was being collected to turn to by heat by area by the past and is being collected.And encourage people that the end-equipment heating radiator of heating is carried out Energy Saving Control, and to come therefrom, the structure of control radiator valve is also changing, and is promptly changed to controlled motorized valve by traditional hand valve.But common motorized valve often is only limited to switch control, and its weak point is:

1, lacks power-off protection.When power supply stops, control fails, pipeline and heating radiator have the danger of bursting by freezing;

2, means of communication falls behind.The general wire communication mode that adopts when being connected with other control module, and its wiring influences interior decoration;

3, function singleness.

The utility model content

The technical problems to be solved in the utility model is, the defective at prior art exists provides a kind of intelligent control valve, and this valve can be controlled the heating of heating radiator automatically, has temperature control, power-off protection, radio communication with functions such as heating gas heat meterings.

Technical solution of the present utility model is, described intelligent control valve, and referring to accompanying drawing 1, this valve has a CPU processor 5 and a motorized valve 11.Its technical characterstic is that described CPU processor 5 is connected to man-machine interface 1, radio-frequency unit 2, communication interface 4, integrated temperature sensor 6, temperature measurement circuit 7, valve driving circuit 13 and standby rechargeable battery 14.Wherein said temperature measurement circuit 7 is connected to two temperature sensors 9, and described valve driving circuit 13 connects said electric valve 11.

Below the utility model is made into explanation.

Above-mentioned intelligent control valve generally is applied in the building and heating metering system, can use radio communication and main control system 3 to get in touch by radio-frequency unit 2, need not be particularly suitable for the transformation of existing building in indoor rewiring.If in new building, also can use wire communication to be connected by communication interface 4 with main control system 3.Come therefrom, intelligent control valve can be linked in the building and heating metering system by radio communication or wire communication, finish many other functions, as Energy Saving Control, can realize that the people comes the effect that heating installation is opened, the people walks the heating installation pass, can also realize heat household metering, fault self-checking survey and the management etc. of paying the fees.

Two temperature sensors 9 in the above-mentioned intelligent control valve generally are installed in the water inlet pipe and rising pipe of heating radiator 8, cooperate temperature measurement circuit 7 can measure the inflow temperature and the leaving water temperature of heating radiator 8.And integrated temperature sensor 6 can be measured indoor environment temperature.According to thermal technology principle, CPU processor 5 can calculate the heat exhaustion value of heating radiator 8 according to the parameters such as opening time of Inlet and outlet water temperature, indoor environment temperature and the motorized valve 11 of heating radiator 8, and this value can be used as the reference data of heat household metering.

Indoor nobody the time, for energy-conservation, generally the heating of heating radiator 8 is closed, but is reduced to zero degrees celsius when following when temperature, cause frost crack pipe easily.CPU processor 5 is according to the Inlet and outlet water temperature of the heating radiator 8 of above-mentioned measurement, and the unlatching of controlling motorized valves 11 by valve driving circuit 13 makes heating radiator be in keeping warm mode, thereby makes pipeline not by bursting by freezing.

Described CPU processor 5 is gone back scalable motorized valve 11 by valve driving circuit 13, with the water supply flow of control heating radiator 8.Indoor temperature is stabilized in is provided with near the temperature, create a pleasant living environment.

Described man-machine interface 1 can make this intelligent control valve be in automatically and manual two kinds of duties.When being in auto state, intelligent control valve is finished above-mentioned automatic control, heating installation metering, low-temperature protection and adjustment; When being in manual state, promptly manually finish out valve/pass valve events by man-machine interface 1.

Described CPU processor 5 has standby rechargeable battery 14, when power supply stops, can opening motorized valve 11 automatically, makes heating radiator 8 be in the heating state, prevents that pipeline is by bursting by freezing.Power just often, external power source is given standby rechargeable battery 14 chargings.

The beneficial effects of the utility model are that the intelligent control valve of Gou Chenging has following advantage than prior art thus:

1, this valve can be linked in the building and heating metering system by radio communication, need not in indoor rewiring;

2, has heating heat metering function;

3, have two kinds of functions of low-temperature protection and power-off protection, can avoid the bursting by freezing of heating radiator pipeline;

4, motorized valve, temperature survey and control system can be merged into a device, further reduce cost, realize the miniaturization of valve control device, make building and heating metering system have more practicality;

5, can link to each other with main control system, whether the existence of the radio-frequency identification card of carrying according to the user, and the turnover of judging the user whether.And the keying of may command valve realizes that the people comes heating installation to open, and the people walks heating installation closes.
