It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of heat supply network balance system, as shown in figure 1, including water inlet pipe 101 and return pipe 102；Pressed on the water inlet pipe 101
Water (flow) direction is sequentially provided with filter 5, water pump 2 and user side inflow temperature sensor 11；Current side is pressed on the return pipe 102
To setting gradually user side return water temperature sensor 12, manual balanced valve 3 and differential pressure control valve 1 with flow regulating function；Institute
State and check-valves 4 is provided between water inlet pipe 101 and return pipe 102；The water pump 2 is provided with frequency converter；Room is also equipped with outdoor
Outer temperature sensor 7；The user side inflow temperature sensor 11, user side return water temperature sensor 12 and outdoor temperature pass
Sensor 7 is connected by circuit with the controller 6 with weather compensation function, and controller 6 also connects differential pressure control valve 1 simultaneously
And control its aperture；Thermometer 9 and pressure gauge 10 are equipped with the water inlet pipe 101 and return pipe 102, and in water inlet pipe 101
Both ends and the both ends of return pipe 102 are designed with shut-off valve 8 respectively.
It should be noted that the differential pressure control valve 1 with flow regulating function possesses the function of stable pressure difference, it is in order to more accurate
True de-regulation heat supply network balance system, do not disturbed by heat supply network secondary side supervisor's net.Also add the bypass design of check-valves 4 can be with
Make user side backwater intake with system primary side to mix, make full use of the energy of user side backwater, enter to reduce system primary side
The flow of water.Heating plant can only calculate quantitative to reach user's heating demands according to parameters such as area of heat-supply services in the prior art
Flow heat supply, this flow causes heat supply network near-end user to overheat, and remote subscriber is warm.And after being mounted with this heat supply network balance system,
Flow needed for net extraction intelligently can be responsible for, now heat supply network from heat supply network secondary side according to the demand of every building all the time
Secondary side supervisor's net is variable flow system.
When user side return water temperature is low, system can give the signal of differential pressure control valve 1 one with flow regulating function, keep former
Pressure difference is set, increases the flow of inlet water of heat supply network balance system primary side.When user side return water temperature is high, system can give band
The signal of differential pressure control valve 1 one of flow regulating function, former setting pressure difference is kept, reduce the feed water flow of heat supply network balance system primary side
Amount.
Wherein, one end of the connection of check-valves 4 water inlet pipe 101 is between filter 5 and water pump 2, connects return pipe
102 one end is between manual balanced valve 3 and differential pressure control valve 1.
Wherein, the check-valves 4 is the caliber identical Wafer Check Valves with water inlet pipe 101 and return pipe 102.It is easy to
Select and purchase, it is easy for installation, while caliber is identical, will not produce the pressure loss.
Wherein, the check-valves 4 is the caliber identical slowly closed silencing formula check-valves with water inlet pipe 101 and return pipe 102.
It is easy to select and purchase, noise is small, does not disturb residents, and check-valves 4 is identical with the caliber of water inlet pipe 101 and return pipe 102, will not produce pressure
Loss.
Wherein, pressure is designed with the water inlet pipe 101 at the both ends of filter 5 and reads point, in that context it may be convenient to carries out pressure
Test, the pressure condition at the both ends of filter 5 is checked, place filter 5 and block.
Wherein, gauge table is installed on the water inlet pipe 101.So, compared with household-based heat metering is transformed, building heating power
Porch is realized measurable, and retrofit work amount and cost substantially reduce, and need not disturb residents.
Wherein, signal projector is installed on the controller 6, be provided with and signal projector wireless connection in heating plant
Monitoring device.Because the signal projector connects the controller 6, so relevant parameter that controller 6 obtains and control
Device signal etc. can be sent to heating plant, and heating plant can be with real-time monitoring equipment operational factor, can also remote control pressure difference control
The aperture of valve 1 processed and the operation of water pump 2.
The situation of every building is different, thus need system can oneself according to demand, flow needed for extraction.So may be used
To reduce the flow of heat supply network secondary side main line, the purpose of energy-conservation is reached.And then it can be built according to difference in functionalitys such as factory, schools
The difference with the hot period is built, timesharing zonal control, realizes energy-saving run；Can for it is different building provide different supply water temperatures and
Output, solves the contradiction of new and old building；Support section building is using different end sides such as floor heating, fan-coil heatings
Formula；Single two-pipe system is supported to coexist.
After installing this heat supply network balance system, according to temperature signal, system reduces primary side inlet flow rate, user's secondary side
By check-valves 4, (check-valves 4 is more than its pressure close to the one end of water inlet pipe 101 to backwater close to an end pressure of return pipe 102
When) mixing primary side water inlet, formed in user's secondary side and circulated.So, heat supply network balance system primary side flow of inlet water reduces, and makes
Enter backwater temperature difference and become big, reach the purpose for saving flow.This system can according to demand, and intelligence carries from heat supply network secondary side supervisor's net
Oneself required flow is derived from, reaches the purpose of energy-conservation.
Because heat supply network balance system user's secondary side backwater can supplement primary side flow of inlet water, therefore make heat supply network secondary side
Netting gear is responsible for for dilatation ability, both can apply to the old system reform, if heating plant main circulation pump flow is constant, heat supply network is once
Side main line is constant, then can be effectively increased existing area of heat-supply service.New system can also be used as to design, avoid the peak hour using thermal source, make
Pipe network possesses dilatation ability.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
