Brief description
Fig. 1 is a kind of structural representation of embodiment of the application；
Fig. 2 is a kind of schematic diagram of embodiment of the application.
Specific embodiment
Combine accompanying drawing below by specific embodiment the present invention is described in further detail.
A kind of testing equipment of international standard tank relief valve, as shown in figure 1, it includes pedestal 1, is provided with pedestal
Cylinder 2 and pressurizer 3, gas connection between cylinder 2 and pressurizer 3.Cylinder 2 upper surface is provided with malleation detection station 22,
When needing to detect relief valve, need for relief valve to be detected to be attached to malleation detection station 22.It is additionally provided with pressure detecting on cylinder 2
Device 4, pressure detector 4 is equipped with pressure inductor at the internal detection station 22 with malleation of cylinder 2, thus detecting cylinder 2
The pressurized pressure of intrinsic pressure and to be detected relief valve, in figure does not show that the arrangement of pressure inductor, and those skilled in the art should
Understand.It is additionally provided with negative pressure device 5 in pedestal 1, pedestal is additionally provided with detection of negative pressure station 23.Wherein, pressurizer 3 can be selected for increasing
Press pump, negative pressure device 5 can be selected for vacuum pump.
As shown in Fig. 2 in the gas circuit between gas circuit UNICOM, and pressurizer 3 and cylinder 2 between pressurizer 3 and cylinder 2
It is sequentially provided with the first cylinder intake valve 211 and the second cylinder intake valve 212.Cylinder exhaust valve 213 is additionally provided with cylinder 2.Negative pressure
Between device 5 and cylinder 2, gas connects, and is additionally provided with negative pressure cylinder valve 214 in the gas circuit between negative pressure device 5 and cylinder 2.Malleation
Detection station 22 is arranged in the gas circuit between cylinder 2 and pressurizer 3 and is connected with this gas circuit, is not installing peace to be detected
During full valve, by malleation, the gas circuit between cylinder 2 and pressurizer 3 detects that station 22 is connected with ambient atmosphere.Detection of negative pressure
Station 23 is arranged in the gas circuit between negative pressure device 5 and cylinder 2 and is connected with this gas circuit.Relief valve to be detected be not installed
When, the gas circuit between cylinder 2 and negative pressure device 5 is connected with ambient atmosphere by detection of negative pressure station 23.
The application has malleation detection and two kinds of mode of operations of detection of negative pressure.Before use, need to arrange cylinder 2 internal gas pressure
Discharge and finish and observe whether pressure value is zero, be not zero, changed and correct.It is zero and be passed through compressed air by cylinder 2
Observe, detect whether malleation value is consistent with cylinder pressure by pressure detector；Inconsistent, carry out changing debugging it is ensured that pressure
Degree of accuracy.
If malleation detection pattern, then relief valve to be detected is attached to malleation detection station 22, closes negative pressure cylinder valve
214 and cylinder exhaust valve 213.Pressurizer is started working, and opens the first cylinder intake valve 211 so that compressed air enters.This
When, need to ensure that in cylinder 2, supply gas pressure have to be larger than the 20% of relief valve requirement experimental pressure value, cylinder exhaust valve 213 can be passed through
To adjust test pressure.Repeatedly fully open and close the second cylinder intake valve 212 within many times, so that relief valve to be detected is beaten
Open or close and close.After completing above-mentioned work, slowly open the second cylinder intake valve 212, allow air pressure to assemble in cylinder 2 and to increase,
Until pressure-testing valve first time gas leakage, pressure at this moment is setup pressure value, if being consistent with performance standard, safe valve performance
Qualified.Afterwards, closing the second cylinder intake valve 212 makes pressure-testing valve playback, and when stopping gas leakage, in cylinder 2, pressure is and resets
Pressure value, if being consistent with performance standard, safe valve performance is qualified.The last sealing property detecting relief valve again, unloads after pressurize
Pressure.
If detection of negative pressure pattern, then close the first cylinder intake valve 211 and the second cylinder intake valve 212, open cylinder
Air bleeding valve 213, makes cylinder 2 release.Again relief valve to be detected is arranged on detection of negative pressure station 23, turns off cylinder exhaust valve
213.Open negative pressure device 5, so that vacuum in cylinder 2 is increased.Slowly open cylinder valve 214, observe whether vacuum meter reading reaches
To setting pressure, if pressure is consistent with performance standard, safe valve performance is qualified.Afterwards, tested the relief valve passing through multiple
Position is it is ensured that air-tightness.After test terminates, take off relief valve.
In above-mentioned test, if the experimental pressure of cylinder 2 is less than or equal to 4.5bar, the malleation experimental pressure of relief valve
The experimental pressure x 5/6 of=cylinder；If the experimental pressure of cylinder 2 is more than 4.5bar, the malleation experimental pressure of relief valve=
The experimental pressure x1.1x2/3 of cylinder.And in above-mentioned test, the malleation of relief valve opens the malleation experiment pressure of scope=relief valve
± the 2.5% of power；The malleation of relief valve completely closes more than the 90% of the actual Opening pressure of scope=relief valve；Relief valve negative pressure
± the 5% of the negative pressure experimental pressure of unlatching scope=relief valve；Cylinder 2 lasts under operating pressure 60 minutes it is desirable to cylinder 2
Each valve body does not have any leakage；Cylinder 2 lasts 30 minutes under fluid power experimental pressure it is desirable to cylinder 2 does not have deformation to let out with any
Leakage.When it meets above-mentioned condition, the performance of relief valve is just qualified.
Above content is to further describe it is impossible to assert this with reference to specific embodiment is made for the present invention
Bright it is embodied as being confined to these explanations.For general technical staff of the technical field of the invention, do not taking off
On the premise of present inventive concept, some simple deduction or replace can also be made.
