1. Kev Sib Raug Kawm Siab
Lub siab kov tau lub peev xwm ntawm pob khoom muaj peev xwm feem ntau sib phim nrog lub siab ntawm cov raj txheej txheem, uas yog muab faib ua peb pawg hauv qab no:
Tsis tshua muaj siab (chav 150-300
Nruab nrab siab (Chav Kawm {600-900): Siab Heev 2. 4 MPa, tshuaj lom neeg thiab lwm yam tshuaj nruab nrab ntawm nruab nrab.
Kev kub siab (chav 1500 thiab tshaj saud): Siab>, siv hauv cov roj thiab roj siv hluav taws xob siab, thiab lwm yam.
2. Cov khoom siv thiab kev ua tau zoo sib cuam tshuam
Lub peev xwm siab ntawm lub pob valve yog ncaj qha rau nws cov khoom:
Carbon Steel (xws li L245): Tawm lub zog ntau dua los yog sib luag rau 415 MPa, rau qhov qis dua thiab sib npaug ntawm 6.4 MPA).
Alloy steel (e.g. X60/X70): yield strength ≥415-485 MPa, can meet the high pressure demand (>10 MPA).
3. Cov lus qhia rau kev xaiv
Kev Lag Luam Kev Lag Luam: Chav Kawm {{0} Pob li qub yog nyiam rau cov xwm txheej qis-siab, thiab chav kawm} rau nruab nrab-siab scenararios.
Kev siv hluav taws xob ntev-deb-Deb
Cov ntsiab lus: Cov siab kov cov khoom li qub ntawm cov li qub npog {}} mpa}} mpa cia ntawm cov txheej txheem siab, xov xwm kev coj ua thiab cov khoom siv tsis sib haum.
