The cleaning of pipeline.
Wherein, second air inlet pipe, the second diaphragm valve, the second pressure regulator valve, the second mass flowmenter, the second filter and
Second check valve is 1/2 inch.
The second diaphragm valve is opened, another gas, such as N2 enter the second intake line, through second by the second air inlet pipe
Pressure regulation pressure regulating valve so that the gas pressure of the second intake line of input is no more than the maximum input pressure of the second mass flowmenter
Power, the second mass flowmenter control the mass flow of the second intake line output gas, N2Into the second intake line through second
Pressure regulator valve and the second mass flowmenter enter the second filter after adjusting separately pressure and mass flow size, after filtering successively
Into the second check valve and the second separator tube, the second check valve determine gas can only one direction enter, ensure that the second input
The cleaning of pipeline.
Gas in the first separator tube, the second separator tube respectively enters mixing tube, is mixed in mixing tube, mixing
Gas afterwards enters output pipe.
Third diaphragm valve determines that output pipe is in the state that is switched on or off, and opens third diaphragm valve, and gaseous mixture enters
Output pipe, pressure is adjusted through third pressure regulator valve, and uninterrupted is adjusted through third mass flowmenter, and it is unidirectional to enter third later
Valve, third check valve determines that gaseous mixture can only exit into working line, and can not flow backwards, and ensure that the clean of output pipe
Only, the 4th diaphragm valve is set on the outside of third check valve, and what the 4th diaphragm valve controlled working line is switched on or off state.
Wherein, first separator tube and the second separator tube are 1 inch.
Wherein, the third diaphragm valve, third pressure regulator valve, third mass flowmenter, third check valve and the 4th diaphragm valve
It is 1/2 inch.
Compared with prior art, advantageous effect of the utility model：The utility model gas mixer is by two kinds
Gas with various is mixed after adjusting separately pressure and flow, and gaseous mixture enters output pipe, and pressure, quality are adjusted through pressure regulator valve
It is discharged into working line after flowmeter adjustment uninterrupted, two kinds of gas with various is realized and exported in mixing, operate and make
With conveniently.
