Operation principle：
The first step：Tested valve is installed
Before the tested relief valve of effect starts, first check whether discharging needle-valve 7 remains on, (prevention gas enters pipe
Road hypertonia, damages 11, No. two verification pressure gauges 12 of a verification pressure gauge) close high pressure admission needle-valve 17, open nitrogen
Bottle 18 valves, the now nitrogen entrance high pressure admission dividing plate 14 in nitrogen cylinder 18, by entering four-way after high pressure admission dividing plate 14
High pressure 2, can observe admission pressure by boost gauge 1, and then gas enters nitrogen decompressor 3, by nitrogen decompressor 3
Enter low pressure threeway 19 after decompression, the pressure of gas can be observed now by decompressed pressure table 4, gas passes through low pressure four-way 20
Afterwards, move towards low-pressure admission dividing plate 15 and air inlet two-position three way cylinder 9 respectively, first with pneumatic gun 16, tested valve is blown off, will
Suppress disk 21 to blow off, tested valve is placed in and suppresses on disk 21, promote fixing three-jaw 22 to fix tested valve.Open air inlet
After two-position three way cylinder 9, gas enters cylinder 13, and cylinder 13 rising is withstood tested valve, makes tested valve inlet end be in sealing
State.
Second step：Test phase
Close discharging needle-valve 7, slow unlatching high pressure admission needle-valve 17, now except air inlet two-position three way cylinder 9 is also to open
State, other valves all process closed mode.Gas enters surge tank 10 after passing through high pressure admission needle-valve 17, now can pass through No. one
Verification 11, No. two verification pressure gauges 12 of pressure gauge are observed admission pressures and whether are met valve test request, A, meet test request
In the case of, gas enters tested valve behind the door, and now tested valve has obvious aerofluxuss, then for qualified；If tested valve shifts to an earlier date
Aerofluxuss or delay aerofluxuss, then tested valve state is unqualified.When gas pressure is less than test request in B, nitrogen cylinder, open supercharging
Pump controls ball valve 5, then booster pump 6 starts, by the pressure boosting in high pressure admission needle-valve 17 to surge tank 10 pipeline, to meeting survey
Examination required pressure, enters surge tank 10, and in the case of meeting test request, gas enters tested valve behind the door, now tested valve
Door has obvious aerofluxuss, then for qualified；If tested valve prerelease or delay aerofluxuss, tested valve state is unqualified.
3rd step：Test terminates
Open discharging needle-valve 7, after venting, be then turned on two-position three way and exit cylinder 8 by the gas discharge in cylinder 13, release
Fixing three-jaw 22, tested valve is taken off.
The pressure of nitrogen cylinder 18 only has 16MPA, and tested valve need during pressure 20MPA could be if aerofluxuss, then, open
Opening booster pump control ball valve 5 startup booster pump 6 thus can be by the pressure in high pressure admission needle-valve 17 to surge tank 10 pipeline
Boosting, when observing 11, No. two verification pressure gauges 12 of a verification pressure gauge to enough pressure is, the whether aerofluxuss of tested valve, accords with
Close the obvious aerofluxuss of test request, then tested valve state is qualified.Will if pressure exceedes test to test request or pressure
Seeking Truth ability aerofluxuss, then tested valve state is unqualified.
Two pressure gauges, 11, No. two verification pressure gauge 12 prevention inspections of a verification pressure gauge must be installed on surge tank 10
Measuring pressure malfunctions.
This utility model structure is novel, and construction is unique, and the pressure that require to detect can be exceeded with the safety of nitrogen pressure
Valve is verified, and not only expands the verification scope of common verifying attachment, also saves the cost of verifying work, in addition, buffering
The setting of tank also avoid gas and enters the too fast caused pressure at expulsion of tested valve testing out of tested valve and reality
Border use in the inconsistent situation of pressure at expulsion, the calibration equipment that it also avoid being led to because of error is dangerous in actual use
The situation of coefficient lifting occurs.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that the containing of equivalency that will fall in claim
All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as limiting
Involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment only wraps
Containing an independent technical scheme, only for clarity, those skilled in the art should for this narrating mode of description
Using description as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined
Understandable other embodiment.
