As shown in Figure 1, air-extractor 30 is not yet opened, and solenoid valve 700 is in the second state (second valve plug 720 sealing the second valve openings 430 and the first valve plug 710 depart from the first valve opening 420).Under this state, the first valve 530 is subject to compressing of the first elastic component 540 and seals intake valve port 131, and the second valve 630 is subject to compressing of the second elastic component 640 and seals the valve port 132 of giving vent to anger, make gas regulating controller 10 in closed condition to prevent gas leakage.
As shown in Figure 3, solenoid valve 700 is converted to the first state (first valve plug 710 sealing the first valve openings 420 and the second valve plug 720 depart from the second valve opening 430) from the second state, and the second air cavity 122 is communicated with the 3rd air cavity 141 by connecting pipeline 20 and the second valve opening 430.When air-extractor 30 running, the gas in the second air cavity 122 and the 3rd air cavity 141 can be pulled out (direction that gas flow direction is as indicated in arrow c) and make the second air cavity 122 and the 3rd air cavity 141 produce negative pressure.Then, when the formed external force of draught head of 122 of the first air cavity 121 and the second air cavitys is greater than the elastic force of the first elastic component 540, the first 200, barrier film can start flexible deformation and drive the first valve 530 along the indicated direction displacement of arrow b, and when the formed external force of draught head of 142 of the 3rd air cavity 141 and the 4th air cavitys is greater than the elastic force of the second elastic component 640, the second 300, barrier film can start flexible deformation and drive the second valve 630 along the indicated direction displacement of arrow a.Thus, being connected the intake valve port 131 of runner 130 and the valve port 132 of giving vent to anger all can maintain opening state and make gas regulating controller 10 in gas feed status.That is to say, methane gas can flow into gas regulating controller 10 from suction port 110, and flows into connecting pipeline 20 (direction that gas flow direction is as indicated in arrow c) by air outlet 150 and the first entrance 22.
In addition, when air-extractor 30 running, can make in the lump air flow into connecting tube portion from the second entrance 24, make mix and flow to gas stove or water heater from mixed export 26 with the gas flowing into from the first entrance 22 from the second entrance 24 leaked-in airs.
As shown in Figure 4, air-extractor 30 maintains the state of bleeding, but solenoid valve 700 is from the first replying state to the second state (second valve plug 720 sealing the second valve openings 430 and the first valve plug 710 depart from the first valve openings 420), the second air cavity 122 is no longer connected with the 3rd air cavity 141 and makes the air pressure of the second air cavity 122 gradually level off to the air pressure of the first air cavity 121.When the formed external force of draught head of 122 of the first air cavity 121 and the second air cavitys is less than the elastic force of the first elastic component 540, the elastic force of the first elastic component 540 again makes the first valve 530 sealing intake valve ports 131 and allows gas regulating controller 10 switch to closed condition, to prevent gas leakage.
In sum, when solenoid valve 700 is during in the first state, can gas regulating controller 10 self closing states be switched to gas drive condition by the driving of air-extractor 30, yet, when having the doubt of gas leakage, even if air-extractor 30 is still in the state of bleeding, the user also state of changeable solenoid valve 700 (switching to the second state from the first state) comes fast gas regulating controller 10 to be switched back to closed condition from gas transmission state, and then promotes the Security of gas regulating controller 10.
According to the disclosed gas regulating controller of above-described embodiment, because solenoid valve not is directly used for driving valve opening or cutting out, but be used for switching the connected state of each air cavity, and by the draught head of each air cavity, control each pressure difference valve and open or close.Therefore, the power consumption demand of solenoid valve can significantly reduce (approximately only needing 5 volts) and reduce the total power consumption of gas flow regulating controller.
