Usayizi ojwayelekile wamavalvu okuhlola ajwayelekile we-ANSI

Ihlola i-valveyakhelwe, yakhiwe, yakhiqizwa futhi yahlolwa ngokwezinga laseMelika ibizwa ngokuthi yi-American standardhlola i-valve, ngakho-ke ungakanani usayizi ojwayelekile wezinga laseMelikahlola i-valve? Uyini umehluko phakathi kwayo nevalvu yokuhlola ejwayelekile kazwelonke? Njengamanje, usayizi ojwayelekile wezinga laseMelikahlola ama-valveidume kakhulu ukuba iklanywe futhi ikhiqizwe ngokuhambisana namazinga e-API kanye ne-ASME, futhi izindinganiso eziningi zamavalvu ezijwayelekile zaseMelika zivamile emhlabeni. Izilinganiso ezijwayelekile zamavalvu okuhlola i-American Standard zimi kanje: Izindinganiso zokuklama: API 6D, ASME B16.34, API 594, BS 1868, GB/T 12235, GB/T 12236, JB/T 8937 Ubude besakhiwo: ASME B16.10 , API 6D, GB/T 12221 Connection amazinga: ASME B16.5, ASME B16.47, ASME B16.25, GB/T 9113, JB/T 79, HG/ T 20592 Pressure test: API 598, API 6D, GB/T 13927, GB/T 26480 Ingcindezi nezinga lokushisa : ASME B16.34, GB/T 12224 Ukusetshenziswa kwezinga laseMelika ama-valve embulunga ezindaweni ezinomfutho ophezulu Umehluko omkhulu phakathi kwezinga laseMelikahlola ama-valvekanye nezinga likazwelonkehlola ama-valvezimi kanje: 1. Iyunithi ye-diameter okuzisholo ihlukile; 2. Uphawu lwe-flange luhlukile; 3. Ubude besakhiwo buhlukile; 4. Izidingo zokuhlola zihlukile.
