Ubukhulu obujwayelekile be-ANSI-standard hlola valves

Le khasiBheka i-valveyakhelwe, eyenziwe, ekhiqizwayo futhi ihlolwe ngokuya nge-American Standard ibizwa nge-American StandardBheka i-valve, ngakho-ke liyini usayizi ojwayelekile we-American StandardBheka i-valve? Uyini umehluko phakathi kwalo kanye ne-valve ye-National Standard Checkve valve? Njengamanje, usayizi ojwayelekile we-American StandardBheka ama-valvesKudume kakhulu ukuklanywa futhi kukhiqizwe ngokuya ngamazinga we-API nase-ASME, futhi amazinga amaningi we-valve ajwayelekile aseMelika empeleni ajwayelekile emhlabeni. Ubukhulu obujwayelekile bama-valves ajwayelekile e-American Check Valves anjengokulandelayo: Amazinga Okuqamba: API 6D, ASME B16.34, API 5235, i-GB / T 12937, i-ASME B16.5, i-ASME B16.5, ASME B166.47, ASME B16.25, GB / T 9113, JB / T 7592, I-ASM / T 13592, I-ASME B167.34, i-API 6224 Ukusetshenziswa kwengcindezelo yengcindezelo yengcindezelo yengcindezelo ephezulu phakathi kwe-American StandaryBheka ama-valveskanye Nezinga LikazwelonkeBheka ama-valveszimi ngokulandelayo: 1. Iyunithi lobubanzi obuhlukile ihlukile; 2. Uphawu lwe-Flange uhlukile; 3. Ubude besakhiwo buhlukile; 4. Izidingo zokuhlola zihlukile.
