Specific embodiment one：
As shown in Figure 1, the present invention provides a kind of device of displacement tank atmosphere and pressurize, including air source 17, air source 17 go out
Mouth has main valve 18, and evacuates branch 1 comprising sequentially connected first pressure regulator valve 5, venturi 7 and the first connector 8；Pressurising
Branch 2 comprising 15 and the 4th shut-off valve 13 of sequentially connected second pressure regulator valve；The evacuation branch 1 and 2 import of pressurising branch
Connect air source 17；The outlet of pressurising branch 2 is divided into two-way, is sequentially connected the suction inlet of third shut-off valve 10 and venturi 7 all the way, separately
Connect all the way 11 second connector 11 of the second connector for connect be replaced container 12, it is to be understood that pressure regulator valve is unidirectional,
Subentry and outlet, venturi 7 is needed to have purge gass entrance and exit, the suction inlet connection of side to be evacuated when installation
Pipeline.The air source 17 is high pure nitrogen or helium nitrogen mixed gas, as displacement tank atmosphere and the gas of pressurize purposes head
First want harmless, it is helium gas molecules that are fit closely, in addition having molecular weight smaller inside helium nitrogen to select inert gas, can be led to
It crosses smaller gap, has leakage that significant change is more easily seen if any pipeline when pressurize purposes, while helium can also be utilized to examine instrument
It assists leaking hunting, needs the time of pressurize that can shorten to a few minutes, while based on the considerations of the nitrogen containing helium of cost 1%-10%
Gas.Preferably, the air source 17, which exports, is equipped with high-pressure gas pressure table 3, uppe r limit of measurement range 2000psi, generally
The full bottle pressure of common steel cylinder nitrogen has 1700psi or so at 20 DEG C.First pressure regulator valve, 5 rear end is equipped with the first low pressure
Gas gauge 6,15 rear end of the second pressure regulator valve are equipped with the second low-pressure gas pressure gauge 14, and third is installed in 11 front end of the second connector
Low-pressure gas pressure gauge 19, uppe r limit of measurement range 200psi, the general atmospheric pressure that purges is in 90-110psi or so, pressurising air pressure
Power is in 70-100psi or so.
Specific embodiment two：
On the basis of embodiment one, all pipelines of preferably described device are 314 material of stainless steel, may quilt to cope with
Displacement is easy mordant gas, and 314 stainless steel pipes are commonly used in the corrosive gas pipeline of semiconductor factory.
Specific embodiment three：
On the basis of embodiment one, preferably described first connector 8 connects gas absorber 9, if being replaced the gas of container
Contain poisonous and harmful element, it is necessary to there is gas absorber 9 to give adsorption treatment.
Specific embodiment four：
On the basis of embodiment one, preferably described first pressure regulator valve, 5 front end is equipped with the first shut-off valve 4, the second pressure regulator valve 15
Rear end is equipped with the second shut-off valve 16, and the meaning of shut-off valve is that exclusive use is allowed to evacuate branch 1 and pressurising branch 2, another way
It is directly closed from front end, pipeline pollution is reduced also for air source 17 is replaced.
Specific embodiment five：
On the basis of example IV, preferably described first shut-off valve 4, the second shut-off valve 16, third shut-off valve 10 and the 4th section
Only valve 13 is pneumatic operated valve, and for general purge is depending on being replaced the gas property of container, some gas viscosities are larger as simultaneously
It is hypertoxic gas, is such as replaced receptacle and once filled Cl2, then purges number at least at 90 times or more, in order to reduce people
For on-off times, shut-off valve can all be made into pneumatic operated valve.
Purge operations method：Standard-sized sheet the first shut-off valve 4, the second shut-off valve 16, third shut-off valve 10, the 4th shut-off valve 13,
First pressure regulator valve 5 and the second pressure regulator valve 15 purge pipeline, such as dust and moisture, then turn down the first pressure regulator valve 5 and second tune
Pressure valve 15, air pollution pipeline when keeping blowback air that connection is prevented to be replaced container 12, blowback atmospheric pressure 30-40psi；Then dress
The gas absorber 9 for setting the gas that connection is suitble to processing to be replaced dresses suitable appliances for labor protection such as biochemical defence suit and regards harmful gas
Depending on volume property, reconnection is replaced container 12；Third shut-off valve 10 and the 4th shut-off valve 13 are closed, the first pressure regulator valve 5 is adjusted
100psi is arrived with the second pressure regulator valve 15；Third shut-off valve 10 is opened, then opens the valve for being replaced container 12, is purged into evacuating
In the stage, pressure is down to -10psi or less and then closes the first shut-off valve 4 in container 12 to be replaced, then open the 4th shut-off valve 13 into
Enter the pressurising stage, pressurising turns off the 4th shut-off valve 13 after stablizing, finally opens the first shut-off valve 4 and third shut-off valve successively again
10, repeat the above evacuation purging and Plenum Process.
Pressurize operating method：Second connector 11 connects protected pipeline, and pressurising 100psi or so, is then shut off third
Shut-off valve 10 and the 4th shut-off valve 13, and kept for 12 to 24 hours or so, 19 pressure of observation third low-pressure gas pressure gauge declines
All belong to normally in 3psi or so, this is the method for test tube road leakage；Valves leakage is surveyed then to need that tested valve one end is allowed to be positive pressure,
The other end is negative pressure, and whether observation positive pressure reduces, and first test has non-internal leakage, above procedure to pass through evacuation without leakage re-test
It may be implemented with pressurising.
It can obtain, which safely can carry out purging displacement internal gas to toxic and harmful gas container；
The device can carry out pressurize to some equipment and leak hunting, including whether test pipeline has whether leakage, valve have interior leakage.
Disclosed above is only presently preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore makees ground equivalent variations according to the claims in the present invention, be still within the scope of the present invention.
