Detailed description of the invention
Fig. 1 is gas mixer schematic diagram provided by the utility model.
Specific embodiment
It is described below for disclosing the utility model so that those skilled in the art can be realized the utility model.It retouches below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
As shown in Figure 1, gas mixer provided in this embodiment include the first gas source (i.e. gas source 1), the second gas source (i.e.
Gas source 2), gas mixer, storage container and control unit.Gas mixer is existing well-known technique comprising two gases
Input terminal and a gas output end.Storage container is for storing mixed gas.First gas source, the second gas source provide respectively to
Two kinds of gas with various of mixing.First gas source pass sequentially through the first pressure reducing valve RV1, the first solenoid valve EV1, the first counterbalance valve BV1,
One gas input of first flow controller MFC1 connection gas mixer；Second gas source pass sequentially through the second pressure reducing valve RV2,
Second solenoid valve EV2, the second counterbalance valve BV2, second flow controller MFC2 connection gas mixer another input terminal.This
In, pressure reducing valve is used for the high pressure air reducing in gas source to convenient pressure in order to gas mixing.Counterbalance valve is as preferred side
Case, for keeping the forefront pressure of flow controller to stablize that flow is made to keep stablizing.The output end of gas mixer connects
Storage container.Control unit is to the first solenoid valve EV1, second solenoid valve EV2, first flow controller MFC1, second flow control
Device MFC2 processed is controlled, while receiving the pressure test information for the pressure transmitter PT being connected with storage container.
When work, the first gas source, the second gas source are accessed, gas is reduced to by certain pressure by pressure reducing valve RV1, RV2.Control
The numerical value of mass flow controller MFC1, MFC2 are arranged according to required ratio of gas mixture for unit processed.Manual setting counterbalance valve
The pressure of BV1, BV2, it is desirable that its pressure is less than the output pressure of pressure reducing valve RV1, RV2.Pass through control unit opens solenoid valve
EV1, EV2 start mixed gas, and after gas is sufficiently mixed by gas mixer, mixed gas enters storage container.Pressure becomes
Send device PT monitor on-line container inner pressure, when container inner pressure reach setting value when, control unit automatically cut off solenoid valve EV1,
EV2 stops mixed gas, and when container internal pressure is down to certain numerical value, control unit automatically opens solenoid valve EV1, EV2 and continues to mix
Gas, to realize the function of automatic control.
As the improvement of above-described embodiment, counterbalance valve BV1, BV2 are electric-controlled type, are electrically connected with control unit and are controlled by it
(not shown) processed.When gas supply, the identical output pressure value of the setting of counterbalance valve BV1, BV2 avoids the gas of the first gas source
Channelling occurs between the gas of the second gas source, i.e. the gas of the first gas source flows to the second gas source or second through gas mixer
The gas of gas source flows to the first gas source through gas mixer.
The technology contents of the not detailed description of the utility model are well-known technique.
