Usayizi ojwayelekile wama-valve okuhlola e-ANSI-Standard

Iivalvu yokuhlolaoklanywe, wakhiqizwa, wakhiqizwa futhi wahlolwa ngokwezinga laseMelika ubizwa ngokuthi izinga laseMelikaivalvu yokuhlola, ngakho-ke ungakanani usayizi ojwayelekile wendinganiso yaseMelikaivalvu yokuhlolaUyini umehluko phakathi kwayo nevalvu yokuhlola ejwayelekile kazwelonke? Njengamanje, usayizi ojwayelekile wejwayelekile yaseMelikaama-valve okuhlolaithandwa kakhulu ukuthi iklanywe futhi ikhiqizwe ngokuvumelana nezindinganiso ze-API ne-ASME, futhi izindinganiso eziningi zama-valve ajwayelekile aseMelika empeleni zivamile emhlabeni. Ubukhulu obujwayelekile bama-valve okuhlola e-American Standard bulandelayo: Izindinganiso zokuklama: I-API 6D, i-ASME B16.34, i-API 594, i-BS 1868, i-GB/T 12235, i-GB/T 12236, i-JB/T 8937 Ubude besakhiwo: I-ASME B16.10, i-API 6D, i-GB/T 12221 Izindinganiso zokuxhuma: I-ASME B16.5, i-ASME B16.47, i-ASME B16.25, i-GB/T 9113, i-JB/T 79, i-HG/ T 20592 Ukuhlolwa kokucindezela: I-API 598, i-API 6D, i-GB/T 13927, i-GB/T 26480 Isilinganiso sokucindezela kanye nokushisa: I-ASME B16.34, i-GB/T 12224 Ukusetshenziswa kwama-valve e-globe ajwayelekile aseMelika ezindaweni ezinomfutho ophezulu Umehluko omkhulu phakathi kwezindinganiso zaseMelikaama-valve okuhlolakanye nezinga likazwelonkeama-valve okuhlolayilezi ezilandelayo: 1. Iyunithi yobubanzi obujwayelekile ihlukile; 2. Uphawu lweflange luhlukile; 3. Ubude besakhiwo buhlukile; 4. Izidingo zokuhlola zihlukile.
