The pressure of high district described in the present invention shows that detecting unit adopts pressure meter or pressure switch or electro connecting pressure gauge or sensing instrument.Described decompressing unit adopts reducing valve, preferably adopts electromagnetic valve and/or motor operated valve and/or proportional servo valve.Low district pressure shows that detecting unit adopts pressure meter or pressure switch or electro connecting pressure gauge or sensing instrument.Described pressure differential detection unit adopts the pressure differential detection instrument.Described break-make or flow regulating unit comprise: electromagnetic valve, flow regulator and pressure control device.The anti-stop element of described refluence adopts flow-stop valve.
The effect of each unit is as follows among the present invention:
(1) high district's pressure demonstration detecting unit: comprise pressure and show and detection part, be used to detect the pressure of higher-pressure region, and showing the tap water pressure value that detection obtains, the force value that detection is obtained is converted to the signal of telecommunication and is transferred to control module simultaneously, is used for logic control;
(2) decompressing unit: adopt all kinds of reducing valve, the tap water pressure in Jiang Gao district (as 0.8Mpa) is reduced to (as 0.4Mpa) high slightly pressure than low district, prevent to reach the pressure of higher-pressure region owing to " break-make or flow regulating unit " appearance causes the pressure of low-pressure area tap water unusually, booster takes place, and has improved the safety in utilization of this expansion loop;
(3) pressure differential detection unit: be used to detect the pressure reduction whether the decompressing unit two ends possess setting, if two districts of too small explanation decompressing unit of pressure reduction or high-low pressure pressure exists unusual, send alarm signal, played protective effect, further increase the safety of this expansion loop;
(4) break-make or flow regulating unit: the break-make or the Flow-rate adjustment that realize tap water pipe line;
(5) low district pressure shows detecting unit: the pressure that is used for low-pressure area shows and pressure detecting, and the force value that detection is obtained is converted to the signal of telecommunication and is transferred to control module, is used for logic control;
(6) the anti-stop element of refluence: can adopt flap valve, prevent that low-pressure area was to the influence of equipment (mainly being reducing valve) when the higher-pressure region was inapplicable.
When following situation appearred in the tap water pipe network, the present invention brought into operation.
1, low-pressure area equipment fault, low-pressure area controller (perhaps by the means switch) are automatically controlled transmission water supply request signal to the higher-pressure region.
2, the low-pressure area controller is provided with water ebb interval, and opens the higher-pressure region water supply pattern, and when after the time period of setting, the low-pressure area controller transmits the water supply request signal from the trend higher-pressure region.
3, height nip pressure compensator each several part detection signal is eligible:
a。Higher-pressure region pressure meets setting value;
b。High low area pressure reduction meets setting value;
c。Low-pressure area pressure is lower than the startup setting value;
D. transmission in real time can move request signal in the height nip pressure compensator, and when receiving height nip affirmation enabling signal, the compensation water supply pattern begins.
The operating principle of expansion loop of the present invention is as follows: after the compensation water supply pattern begins, high district's pressure demonstration detecting unit is checked the tap water pressure of flowing through, if the tap water pressure value from the higher-pressure region is normal, to the flow through tap water pressure of decompressing unit of decompressing unit drops to setting value, it is poor that the pressure differential detection unit detects the tap water pressure that flows into decompressing unit and flow out decompressing unit simultaneously, meet setting value as tap water pressure reduction, and the force value of the low district low district of pressure demonstration detecting unit detection tap water also just often, open break-make or flow regulating unit, the tap water compensation model starts.If occur closing break-make or flow regulating unit automatically, the concurrent signal that is out of order unusually if any the unit detection signal in the water supply process.When the anti-stop element that flows backwards prevented that break-make or flow regulating unit from breaking down, the low-pressure area tap water poured in down a chimney, the safety when having guaranteed to use.
Break-make or flow regulating unit have two kinds of working methods.
