With pressure 0.6051Mpa, promote piston to move down, the demarcation liquid kept in liquid container 2 is pressed, demarcation liquid flows into be determined
In irregular seal cavity 4；
1. demarcation liquid is remaining in the temporary liquid container 2, is that the volume scale C1 of temporary liquid container 2 is more than and to be determined do not advised
The then volume V of seal cavity 4, now, closing the second electric T-shaped valve 11 is used for what is be connected with irregular seal cavity 4 to be determined
Interface f, and using the level and capacity scale C2 of remaining demarcation liquid in liquid level gauge or the temporary liquid container 2 of Accuracy Flow Meter record, 0
＜ C2≤C1, note the amount of solution of demarcation liquid in the temporary liquid container 2 of observation, when nearly having flowed, close the second valve 9, can keep away
Error in dipping caused by exempting from therefore.Complete irregular seal cavity 4 to be determined to fill, be transferred to step (7)；
2. when the liquid level of demarcation liquid in temporary liquid container 2 is more than 0 scale and close to 0 scale, by the valve port of the second valve
Turn down, the liquid level of demarcation liquid is slowly declined, when the liquid level for demarcating liquid drops to 0 scale, the second valve is closed immediately, this
When, the temporary interior demarcation liquid of liquid container 2 is all introduced into irregular seal cavity 4 to be determined, is the full liquid of temporary liquid container 2
Volume scale C1 is less than or equal to the volume V of irregular seal cavity 4 to be determined, and closing the second electric T-shaped valve 11 is used for treating
The connected interface f of irregular seal cavity 4 is determined, the second valve and the 3rd valve is opened, the demarcation liquid in pipeline is returned
Receive, complete after reclaiming, close the 3rd valve, open the interface d that the second electric T-shaped valve 11 is used to be connected with vavuum pump 5, open
Vacuum extractor, extracts the air in whole pipeline liquid injecting device out, and it is vacuum state to make whole pipeline liquid injecting device；Close the second electric three passes
Valve is used for the interface being connected with vacuum extractor, is then shut off vacuum extractor；Open the first electric T-shaped valve be used for connect the
Liquid working substance in the interface of the vertical main road of one pipeline, fluid reservoir is entered as demarcation liquid in temporary liquid container, when temporary liquid
When the liquid level of demarcation liquid reaches the volume scale C1 of temporary liquid container in container, closing the first electric T-shaped valve is used for and the first pipe
The connected interface of the vertical main road on road, and record the volume scale C1 of temporary liquid container；It is transferred to step (6)；This step n times are repeated,
N >=1, until the level and capacity that the demarcation liquid in temporary liquid container 2 has remaining demarcation liquid in residue, the temporary liquid container 2 of record is carved
The volume scale C1 of C2 and each temporary liquid container is spent, irregular seal cavity to be determined is completed and fills, be transferred to step (8)；
(7) demarcation liquid filling weight is calculated, i.e.,：
V=C1-C2 formula are 1.
It is transferred to step (9)；
(8) demarcation liquid filling weight is calculated, i.e.,：
V=C1 × N+ (C1-C2) formula is 2.
Wherein C1, C2 unit directly obtains this irregular close if milliliter or other volume units after then calculating
The volume of cavity is sealed, needs to be converted if C1, C2 unit are not milliliter or other volume units, body is then obtained again
Product value；
It is transferred to step (9)；
(9) open the first electric T-shaped valve 7 be used for connect the first recovery pipe 8 interface c and the 3rd valve 10, sealed tube
