Description
1, technical field
The present invention relates to a kind of high-zone directly-connected boosting heating system that is used for high rise building heating.
2, background technology
Along with the development of town and country construction, skyscraper is more and more many, therefore, and for skyscraper provides a kind of major issue that economy, reliable heating system just become needs solution of using.The high rise building heating of prior art need set up boiler or heat exchanger mostly separately and carry out the heating system that high and low district is isolated, and its equipment investment is big, the operating cost height, and the heat exchange effect when the heat medium temperature that adopts heat exchanger to carry out heat exchange hangs down is unsatisfactory.Also there is minority to adopt the high-zone directly-connected heating technology of spiral-flow type or traditional choke type to realize using the high rise building heating of same heat supply network, when adopting cyclone mode, the basic flow direction of its indoor pipe system should be down the open state backwater of keeping supplying back, the pipeline construction complexity, the construction costs height, and when unbalance of system, easily cause and metal run out, even can directly cause metalling run out in a large number of system and shut down; Traditional choke type then is to rely on pressure-reducing valve to be equipped with the technical scheme that the heavy caliber magnetic valve is realized the backwater decompression of high district, and its pressure of return water is difficult for regulating, and the performance of magnetic valve is difficult to guarantee that the high-zone directly-connected security of system of skyscraper is relatively poor.
3, summary of the invention
In view of the deficiency that above-mentioned prior art exists, it is simple to the invention provides a kind of configuration structure, takes up an area of to lack, and initial cost is economized, and is reliable, and can realize regulating automatically the high-zone directly-connected boosting heating system of control.
The technical solution adopted for the present invention to solve the technical problems is: high-zone directly-connected boosting heating system is by low district heating and supplying water pipe, booster pump, high district heating and supplying water pipe, high district heating water return pipe, filter, electronic pressure-reducing valve, automatic open and close valve, low district's heating water return pipe and switch board are formed, wherein booster pump directly is connected with low district heating and supplying water pipe through water inlet pipe, be connected with high district heating and supplying water pipe by the outlet pipe behind the booster pump again, be respectively equipped with pressure sensor on water inlet pipe and the outlet pipe, connect high district heating water return pipe behind the high district heating and supplying water Guan Jinggao hot user in district, high district heating water return pipe passes through filter successively along water (flow) direction, be connected with low district heating water return pipe behind electronic pressure-reducing valve and the automatic open and close valve, and before electronic pressure-reducing valve He behind the automatic open and close valve, be respectively arranged with Pressure gauge, behind electronic pressure-reducing valve, be equiped with safety valve and pressure sensor, on outlet pipe He Gao district heating water return pipe, be respectively equipped with thermometer, booster pump, electronic pressure-reducing valve and pressure sensor are wired to switch board respectively.
Electronic pressure-reducing valve is to regulate its outlet pressure automatically according to the setting value that is installed in the pressure sensor behind the electronic pressure-reducing valve; make the pressure of high district heating water return pipe drop to the setting value of being controlled; and it is supporting with the pressure of low district heating water return pipe; realize the pressure of high low area return pipe; flow equilibrium; automatic open and close valve then opens and closes valve for waterpower; the voltage-controlled tubulation of water is connected between automatic open and close valve and the outlet pipe; and control the open and close of automatic open and close valve by the hydraulic pressure in the hydraulic pressure control valve; when booster pump moves; hydraulic pressure in the hydraulic pressure control valve is opened automatic open and close valve; when booster pump shutdown or dead electricity; hydraulic pressure in the waterpower control valve loses; the automatic open and close valve quick closedown separates high district heating water return pipe and low district heating water return pipe, thereby guarantees the partition of high low area system static pressure.
The invention has the beneficial effects as follows, can realize being connected, reach the heating requirement of high-zone directly-connected boosting, need not to set up separately boiler or heat exchanger with the low district heating and supplying water pipe and the direct of return pipe of skyscraper; reduce investment outlay, take up an area of and lack, and simple in structure; easy for installation, control automatically and protect, reliable.
