Operation test excess flow valve
V Prilogi 2C k temu pravilniku so prikazani primeri namestitve homologacijske oznake.
An excess flow valve shall operate at not more than 10 per cent above, nor less than 20 per cent below the rated closing flow capacity specified by the manufacturer, and shall close automatically at a pressure differential across the valve of not more than 100 kPa during the operation tests described below.
ZAHTEVE ZA VGRADNJO POSEBNE OPREME ZA UPORABO UTEKOČINJENIH NAFTNIH PLINOV V POGONSKEM SISTEMU VOZILA
Three samples of each size and style of valve are to be subjected to these tests.
Delovna priključna naprava iz odstavka 17.1.7.3 se dovoli, če tehnične službe, ki opravljajo homologacijo, menijo, da je delovna priključna naprava ustrezno zaščitena in ne vpliva na predpisano delovanje običajnega sistema za uporabo UNP.
A valve intended for use only with liquid is to be tested with water, otherwise the tests are to be made both with air and with water.
Delovna priključna naprava mora biti kombinirana z ločenim protipovratnim ventilom, neprepustnim za plin, kar je edini način za delovanje motorja.
Except as indicated in paragraph 10.2.3 below, separate tests are to be run with each sample installed in vertical, horizontal and inverted positions.
Posode za gorivo se namestijo in pritrdijo tako, da je mogoče vzdržati naslednje pospeške (ne da bi pri tem nastala škoda), ko so posode polne:
The tests with air to be made without piping or other restriction connected to the outlet of the tests sample.
Vozila kategorij M1 in N1:
A valve intended for installation in one position only may be tested only in that position.
8 g v vodoravni legi pravokotno na smer vožnje.
The test with air is to be conducted by utilising a properly designed and calibrated orifice flowmeter of the flange type, connected to a source of air supply of adequate capacity and pressure.
Vozila kategorij M2 in N2:
The test sample is to be connected to the outlet of the flowmeter.
10 g v smeri vožnje;
A manometer or calibrated pressure-gauge reading in increments of not more than 3 kPa is to be installed on the upstream side of the test sample to indicate the closing pressure.
5 g v vodoravni legi pravokotno na smer vožnje.
The test is conducted by slowly increasing the flow of air through the flowmeter until the check valve closes.
6,6 g v smeri vožnje;
At the instant of closing, the pressure differential across the flowmeter orifice and the closing pressure indicated by the gauge are to be recorded.
Če je več kot ena posoda za UNP povezana samo z eno dovodno cevjo, mora biti vsaka posoda opremljena s protipovratnim ventilom, nameščenim za daljinsko vodenim servisnim ventilom, razbremenilni ventil cevi pa mora biti nameščen v dovodno cev za protipovratnim ventilom.
The rate of flow at closing is then to be calculated.
Ustrezen filtrirni sistem je treba namestiti pred protipovratnimi ventili za preprečitev nabiranja umazanije na njih.
Other types of flowmeters and a gas, other than air, may be used.
Protipovratni ventil in razbremenilni ventil cevi nista potrebna, če nepovratni tlak daljinsko vodenega servisnega ventila v zaprtem položaju preseže 500 kPa.
The test with water is to be conducted using a liquid flowmeter (or equivalent) installed in a piping system having sufficient pressure to provide the required flow.
V tem primeru mora biti kontrolna naprava daljinsko vodenih servisnih ventilov izdelana tako, da se nikoli ne odpre več kot en daljinsko voden ventil.
The system is to include an inlet piezometer or pipe at least one pipe size larger than the valve to be tested, with a flow control valve connected between the flowmeter and piezometer.
Razbremenilni vzmetni ventil se namesti v posodo za gorivo tako, da je povezan s prostorom za paro in lahko gorivo izpusti v ozračje.
A hose or hydrostatic relief valve, or both, may be used to reduce the effect of the pressure shock when the excess flow valve closes.
Razbremenilni vzmetni ventil lahko gorivo izpusti v ohišje, neprepustno za plin, če to izpolnjuje zahteve iz odstavka 17.6.5.
The test sample is to be connected to the outlet end of the piezometer.
Če je plinska cev, druga cev ali katera koli električna napeljava nameščena v povezovalni gibki cevi in vodu, mora prosta odprtina prav tako meriti najmanj 450 mm2.
A manometer or calibrated pressure gauge of the retard type, which will permit readings in the range of 0 to 1440 kPa is to be connected to a pressure take-off on the upstream side of the test sample to indicate the closing pressure.
Ohišje, neprepustno za plin, in povezovalne gibke cevi ne smejo puščati pri tlaku 10 kPa z zaprtimi odprtinami in pri največji dovoljeni stopnji puščanja 100 cm3/h ne smejo kazati trajnih deformacij.
The connection is to be made using a length of rubber hose between the pressure gauge and the pressure take-off, with a valve installed at the gauge inlet to permit bleeding air from the system.
Spajkani ali varjeni spoji in krčni nasedi ozobljenega tipa niso dovoljeni.
Prior to the test, the flow control valve is to be opened slightly, with the bleed valve at the pressure gauge open, to eliminate air from the system.
Spajkanje ali varjenje se lahko dovoli za povezovanje posameznih delov odstranljivih priključnih naprav na plinsko togo cev ali njen sestavni del.
The bleed valve is then to be closed and the test is conducted by slowly increasing the flow until the check valve closes.
Plinske toge cevi morajo biti povezane z ustreznimi spoji, na primer z dvodelnimi krčnimi nasedi v jeklenih ceveh in spoji z navojnimi obroči na obeh straneh ali dvema prirobnicama v bakrenih ceveh.
During the test the pressure gauge is to be positioned at the same level as the test sample.
Plinske toge cevi morajo biti povezane z ustreznimi priključki.
At the instant of closing, the rate of flow and closing pressure are to be recorded.
Nikakor pa se ne smejo uporabiti priključne naprave, ki poškodujejo cev.
When the excess flow valve is at cut-off position, the leakage or by-pass rate of flow is to be recorded.
Tlak porušitve nameščenih priključnih naprav mora biti enak ali višji, kot je določen za cev.
An excess flow valve used in the assembly of a filling unit shall close automatically at a pressure differential of not more than 138 kPa when tested as described below.
V prostoru za potnike ali zaprtem prtljažniku ne sme biti priključkov za dovod plina, razen:
Three samples of each size of valve are to be subjected to these tests.
priključkov na ohišju, neprepustnem za plin; in
The tests are to be made with air, and separate tests are to be run with each sample mounted vertically and horizontally.
priključka med plinsko togo ali gibko cevjo in polnilno enoto, če ima ta priključek oblogo, ki je odporna proti UNP in se vsak uhajajoč plin izpusti neposredno v ozračje.
