Ubungakanani obuqhelekileyo beevalves ze-ANSI

IJonga i-valveyenziwe, yenziwe, ivelisiwe kwaye ivavanywa ngokomgangatho waseMelika kubizwa ngokuba ngumgangatho waseMelikaJonga i-valve, yintoni le ubungakanani obuqhelekileyo bomgangatho waseMelikaJonga i-valve? Nguwuphi umahluko phakathi kwayo kunye ne-valve yesizwe esiqhelekileyo? Okwangoku, ubungakanani obuqhelekileyo bomgangatho waseMelikaJonga i-valvevesIthandwa kakhulu yile iyiyilwe kwaye iveliswe ngokwemigangatho ye-API kunye ne-ASM, kwaye imigangatho emininzi yaseMelika eqhelekileyo ixhaphakile emhlabeni. Imilinganiselo esemgangathweni yeeVali zeAmerican Sokhemba zezi zilandelayo: IMigangatho yoYilo: I-API 6D / T I-ASTE B1637, GB / T 122.5, i-ASTE B16.47, i-Asme I-B16.25, GB / T 9113, JB / T 78, I-ASME 598 4, GB / T i-GB / T I-GB / T 62.3, GB / T 62.3Jonga i-valveveskunye nomgangatho wesizweJonga i-valveveszezi zilandelayo: 2.
