Ama-valve esango asetshenziselwa ukuvala ukugeleza koketshezi esikhundleni sokulawula ukugeleza. Uma ivuliwe ngokugcwele, i-valve yesango evamile ayinakho ukuvinjelwa endleleni yokugeleza, okuholela ekuphikiseni ukugeleza okuphansi kakhulu.Ubukhulu bomzila ovulekile wokugeleza ngokuvamile buhluka ngendlela engaqondile njengoba isango lihanjiswa. Lokhu kusho ukuthi izinga lokugeleza alishintshi ngokulinganayo ngokuhamba kwesiqu. Kuye ngokwakhiwa, isango elivuliwe kancane lingadlidliza lisuka ekugelezeni kwamanzi.

Umdwebo Wemikhiqizo
Amazinga Okusebenza
1.Dizayina futhi wenze ngokuvumelana ne-API 602,BS5352,ANSI B 16.34
2.Uxhumano luphela kusukela ku-:
1) Ubukhulu be-Socket weld buhambisana ne-ANSI B 16.11, JB/T 1751
2) Ubukhulu beziphetho zesikulufa buhambisana ne-ANSI B 1.20.1,JB/T 7306
3)I-Butt-Welded ihambisana ne-ANSI B16.25,JB/T12224
4)Iziphetho ezicashile zihambisana ne-ANSI B 16.5,JB79
3. Ukuhlolwa nokuhlolwa kuhambisana nalokhu:
1)API 598,GB/T 13927,JB/T9092
4.Izici zesakhiwo:
Ibhonethi eboshiwe, isikulufu sangaphandle nejoka
Ibhonethi eshiselwe, ama-scres angaphandle kanye nejoka
5.Izinto ezisetshenziswayo zihambisana ne-ANSI/ASTM
6.Izinto ezibalulekile:
I-A105,LF2,F5,F11,F22,304(L),316(L),F347,F321,F51,Monel,20Alloy
