Usayizi lojwayelekile we-ANSI-Emavalvu ekuhlola lajwayelekile

Ihlola ivalvuyakhelwe, yakhiwe, yakhicitwa futsi yahlolwa ngekuya kwelizinga laseMelika ibitwa ngekutsi lizinga laseMelika .hlola ivalvu, ngako-ke yini linani lelijwayelekile lelijwayelekile laseMelika .hlola ivalvu? Yini umehluko emkhatsini wayo kanye ne-valve yekuhlola lejwayelekile yavelonkhe? Kwanyalo, usayizi ejwayelekile wezinga laseMelika .hlola emavalvuithandwa kakhulu kutsi yakhelwe futsi ikhicitwe ngekuhambisana nemazinga e-API kanye ne-ASME, futsi emazinga lamanyenti e-valve lajwayelekile aseMelika empeleni avamile emhlabeni. Tilinganiso letijwayelekile temavalvu ekuhlola e-American Standard tinjengaleti: Emazinga ekuklama: 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 Budze besakhiwo: emazinga: ASME B16.5, ASME B16.47, ASME B16.25, GB/T 9113, JB/T 79, HG/T 20592 Kuhlolwa kwemfutfo: API 598, API 6D, GB/T 13927, GB/T 13927, GB/T 26480 Kucindzeteleka kanye nekushisa B3. 12224 Kusetjentiswa kwemavalvu emhlaba lajwayelekile aseMelika etindzaweni letinemfutfo lomkhulu Umehluko lomkhulu emkhatsini welizinga laseMelika .hlola emavalvukanye nelizinga lavelonkhehlola emavalvukukhona ngalendlela lelandzelako: 1. Iyunithi diameter nominal ehlukile; 2. Liphawu le-flange lehlukile; 3. Ubude besakhiwo buhlukile; 4. Tidzingo tekuhlola tehlukile.
