Umehluko phakathi kwe-API 607 ​​​​ne-6FA: Ukuhlolwa Komlilo Kwama-Valve

I-API 607 ​​​​kanye ne-API 6FAUkuhlolwa komlilo kwama-valve angu-6D no-6A. Ngokuvamile, ama-valve angu-6D angajikeleza ngo-90° kuphela kudingeka enze i-API 607, kanti amanye kudingeka enze i-API 6FA. I-API yisifinyezo se-American Petroleum Institute, kanti i-6FA iyisivivinyo somlilo sama-valve ajwayelekile angu-6A.

Ukuhlolwa kwamavalvu ngomlilo kusetshenziselwa ukuqinisekisa ukusebenza kahle kwamavalvu ngesikhathi somlilo nangemva komlilo. Amavalvu anjalo avame ukusetshenziswa ngezikhathi ezithile lapho kunezingozi zomlilo ezingaba khona. Ngesikhathi sokuklama, kufanele kucatshangelwe ukuthi asenamandla athile okuthwala ingcindezi, ukusebenza kahle kokuvala kanye nokusebenza kahle lapho eshiswa isikhathi esithile.

Izindinganiso Zokuhlola Umlilo Zamavalvu:

1. I-API 607-2016: Ukuhlolwa Komlilo Kwama-Valve Nama-Valve Ajika Ngamakota Ahlonyiswe ngezihlalo ezingezona ezensimbi

Ububanzi besicelo:Amavalvu anokujika okungu-1/4 kanye namavalvu anezihlalo ezingezona ezensimbi. Njengalokhu:ivalvu yebhola, ivalvu yebhabhathane, i-plug valve

2. I-API 6FA-2018: Imininingwane Yokuhlolwa Komlilo Kwama-Valve

Ububanzi besicelo:Amavalvu e-API 6A kanye ne-API 6D. Njengalokhu:ivalvu yebhola, ivalvu yesango, i-plug valve.

3. I-API 6FD-2008: Imininingwane Yokuhlolwa Komlilo Kwama-Check Valve

Ububanzi besicelo:I-valve yokuhlola

Amaphuzu okuqinisekisa ukuvikelwa komlilo e-API 6FA

Ukuhlolwa kokusebenza kuwukusebenzisa ivalvu ngaphansi kokucindezela kokuhlolwa komfutho ophezulu okuchazwe ku-standard. Ivalvu isuka ekuvalweni ngokuphelele iye ekuvulekeni okuyingxenye noma evulekile ngokuphelele, bese umusi osepayipini ucinywa ukuze ugcwalise ipayipi ngamanzi. Bese ipayipi elingezansi livalwa bese ukuvuza kwangaphandle kwevalvu kulinganiswa ngaphansi kokucindezela kokuhlolwa komfutho ophezulu okuchazwe ku-standard. Ukuhlolwa kokucindezela okuphansi ngemva kokupholisa ukuvuza kwangaphakathi nangaphandle kwevalvu okulinganiswe kungcindezi yokuhlolwa komfutho ophansi okuchazwe ku-standard ngemva kokuba ivalvu iphoqelekile ukupholisa ngemva komlilo. Ukuvuza kwangaphandle ngesikhathi somlilo kubhekisela ekuvuza ngokuxhumeka kwe-flange yomzimba wevalvu, uxhumano olunezintambo kanye nophawu lwe-valve stem ngesikhathi somlilo ngaphansi kokucindezela kokuhlolwa okucacisiwe. Ukuvuza kwangaphakathi ngesikhathi somlilo kubhekisela ekuvuza ngesihlalo sevalvu ngesikhathi somlilo ngokucindezela kokuhlolwa okucacisiwe.

Ukumbozwa kokuhlolwa komlilo kwe-API 607/6FA valve

Ukumbozwa kwe-API607 ne-API6FA kuhlukile. Ukumbozwa kuhlukaniswe kakhulu ngosayizi, ukumbozwa kwezinga lokucindezela, ukumbozwa kwezinto ezibonakalayo nezinye izici.

Kunomehluko omkhulu ekukhetheni ingcindezi yokuhlola. Phakathi kwazo, ingcindezi yokuhlola ephansi echazwe ku-API607 ingu-0.2MPa, kanti ingcindezi yokuhlola ephezulu ingu-75% wengcindezi ephezulu evumelekile kuma-degrees angu-20, kuyilapho ingcindezi yokuhlola ephansi kanye nengcindezi yokuhlola ephezulu echazwe ku-API6FA kuhlobene nebanga le-valve pound.

I-API 607ibeka ukuthi ama-valve okuhlola i-ferrite angamboza ama-valve enziwe ngezinto zensimbi ze-austenite neze-duplex, kodwa ama-valve anobukhulu obuphakathi nendawo ebangeni lokumboza nawo kumele aphumelele ukuhlolwa.

Indlela yokuhlola ye-ISO15540 yokumelana nomlilo kwemihlangano yamapayipi emikhumbi

Indlela yokuhlola ye-ISO15541 yokumelana nomlilo kwemihlangano yamapayipi emikhumbi

Ukuhlolwa kobubanzi kanye nenani lokucindezela kokuhlolwa kokuphepha komlilo we-valve:

Esivivinyweni sokumelana nomlilo we-valve, ububanzi kanye nenani lokucindezela yizo ezincane kakhulu ezimboza usayizi omkhulu, isibonelo:

Ngokuvamile, ububanzi bumboza imininingwane ephindwe kabili, ama-NPS angu-6 angamboza ama-NPS angu-6-12, ama-DN angu-100 angamboza ama-100-200DN;

Ukuze kuhlolwe isilinganiso sokucindezela, ububanzi bokumbozwa bucacisiwe, i-25PN ingamboza i-25-40PN
