A kind of working principle of the device of two-component gas ratio dispatching of the present invention is:
Gas Ratio Miring Device: two kinds of gas sources open air inlet, intake pressure selection by two two-position two-way solenoid valves 4
1.06bar, gas charge cylinder 3, check valve 1 set pressure as 1.05bar, can air pressure (gas in preliminary control amount cylinder 3
Portion gas washes check valve open and enters gas bottle when pressing high), travel switch 5 is touched in left and right after being full of, and makes bi-bit bi-pass reversal valve 4
Commutation, compares into pressure；Pressure comparison phase, the liquid level sensor 10 at U-tube 9 (built-in certain liq) start to act as
With when there are pressure difference in two sides, 9 two sides liquid level sensor 10 of U-tube detects that liquid level changes, and gives a pulse signal, makes pressure
It is small over there into a small gangs of gas, the gas pressure intensity phase in two amount cylinders 3 of explanation when both sides are all not responding to sensor for a period of time
Deng into the gas mixing stage；The gas mixing stage presses lower switch after pressure is completeer, keeps 2 promotion ratio of motor push rod big
Gas be first filled with mixed cylinder 3, after being filled with completely trigger travel switch 5, make two-position two-way solenoid valve 4 commutation re-fill gas
Body so recycles, and ratio, which reaches, after rear necessary requirement while to be pressed the electric pushrods of two sides and switch, and mixes all gas
It closes.
Gas essence amount dispenser: not having water in container 18 at the beginning, first controls water pump 20 and fills the water into container 18, works as water
When position reaches lower setting value, air inlet solenoid valve 14 is opened, is passed through gas, and open gas outlet solenoid valve 15, container is discharged
Original gas in 18 closes gas outlet solenoid valve 15 and continues to ventilate after a period of time, pressure sensor 16 can monitor container 18
Interior pressure, when air pressure reaches setting value in container 18, water pump 20 starts to fill the water, and opens simultaneously gas outlet solenoid valve 15, works as water
When position reaches higher setting value, stop pumping, and close gas outlet solenoid valve 15, discharge outlet solenoid valve 21 is opened, and container is discharged
Liquid in 18, to reach the gas delivery of more smart amount.
Compared with prior art, the beneficial effects of the present invention are:
Due to judging whether two container air pressures are equal with whether U-tube liquid level is equal, can relatively accurately control
The air pressure of two containers of system left and right is to get the amount for arriving two more accurate component gas, and repeatedly exhaust is to accurately control gaseous mixture
Body ratio.
Since the mode changed with liquid level dispenses gas, and solubility is all very low in water for many gases, while air pressure transmission
Sensor control container in air pressure constant, therefore with liquid level change mode drain can be more accurate dispatching mixed gas.
