Specific embodiment
The composition and working principle of the utility model is shown in Figure 1.A kind of self-operated type balance heating system, including it is primary
Net, plate heat exchanger, secondary network, water replanishing device and injection pump installation；Primary net includes sequentially connected on a network management line
Heating plant or boiler water outlet, primary net circulating pump, plate heat exchanger first medium end, electric control valve and heating plant or
Person's boiler blow-down water mouth；Secondary network includes the secondary pipe at plate heat exchanger second medium end, connecting plate type heat exchanger second medium end
Cable water outlet and water return pipeline, with the water outlet of the secondary pipe cable at plate heat exchanger second medium end and water return pipeline respectively by
The injection pump installation installed additional before building realizes one group of heat supply user unit of connection, two be serially connected in secondary pipe cable water return pipeline
The water supply tank and small pump of secondary net circulating pump and secondary network；In being separately installed with for backwater end for return water teletransmission pressure for jet pump
Table is also connected with according to the pressure difference for return water distance-transmission pressure gauge, realizes the bypass pressure difference electric control valve of aperture control.
Working principle:
1. can solve heating system hydraulic misadjustment problem by installing jet pump additional in user Lou Dong or unit entrance, mention
The hydraulic stability of high heating system makes heat user room temperature tend to be uniform.
2. if perhaps the system resistance of unit occupancy rate variation building or unit entrance can be therewith for user Lou Dong occupancy rate
Variation, water supply distance-transmission pressure gauge 10 and return water distance-transmission pressure gauge 11 show that numerical value changes, corresponding water supply distance-transmission pressure gauge 10
It can change with the difference of return water distance-transmission pressure gauge 11.To guarantee that jet pump in the continually changing situation of occupancy rate, sprays
Amount and injection volume are able to satisfy system requirements, need to use the fixed aperture that bypass pressure difference electric control valve is controlled for return water pressure differential method, i.e. root
It presets according to the system form in every building or unit for return water pressure difference, when occupancy rate reduces in building, system resistance is therewith
Increase, the difference of water supply distance-transmission pressure gauge 10 and return water distance-transmission pressure gauge 11 increases, and pressure difference motorized adjustment valve opening will become larger, directly
Reach pre-set for return water pressure difference to for return water pressure difference；When occupancy rate increases in building, system resistance reduces therewith, supplies
The difference of water distance-transmission pressure gauge 10 and return water distance-transmission pressure gauge 11 reduces, and pressure difference motorized adjustment valve opening will become smaller, until supplying back
Differential water pressures reach pre-set for return water pressure difference.
3. can by using the method that user Lou Dong or unit entrance install jet pump and bypass pressure difference electric control valve additional
To realize that system self-operated type balances.
