Qhov xav tau rau kev kho tshuab cais tawm
Xaiv kev rho tawm cov qauv rau cov txheej txheem ntws
A) ib leeg-kev sib cais-valve, uas yog, qhov yuav tsum tau nyob ib leeg ntawm cov khoom siv tau pom zoo los ntawm kev kaw ib lub valve ntawm qhov nkag thiab tawm ntawm cov cuab yeej, cov chaw thiab cov khoom siv. Haum rau kev rho tawm ntawm cov kab ke uas tsis muaj qhov sib cais tsawg ntawm qhov yuav tsum tau muaj, xws li kev cais tawm ntawm cov tshuab nrog qhov tso tawm sab hauv thiab qhov hluav taws xob thiab qhov nruab nrab tsis txaus; Lub taub yeeb nkab loj tsis txwv thiab nce siab siab tsis yog dej hiav txwv siab, dej tua hluav taws, dej txias thiab lwm yam kev tshaj tawm raj xa dej; Thiab kev rho tawm los ntawm cov pa taws uas tsis muaj kuab lom nruab nrab nrog lub raj xa hluav taws xob tsawg dua (tsawg dua 1MPa) thiab cov yeeb nkab tsis txwv rau qhov loj me.
B) ob txoj kev sib cais-valve thiab rho tawm cov txheej txheem, uas yog, ib txoj kev sib cais los ntawm kev siv ob txoj kab sib cais uas kaw qhov hluav taws xob thiab qhov hluav taws xob ntawm cov khoom siv, chaw thiab khoom siv, thiab tso tawm qhov nruab nrab ntawm ob lub qub thaum tib lub sijhawm. Haum rau kev rho tawm ntawm cov nplaim hluav taws xob ua kua nruab nrab system nrog qis raj xa dej siab (tsawg dua 0.2mpa) thiab cov yeeb nkab sib npaug loj dua (tsawg dua 25.4mm); Kev rho tawm cov pa hluav taws xob tsis muaj pa roj nruab nrab nrog lub nruab siab loj hauv qhov siab (ntau dua 1MPa) thiab cov yeeb nkab tsis muaj qhov txwv loj; Thiab lwm yam kev tshaj tawm hauv cov yeeb nkab tshwj xeeb loj thiab lub kaw lus siab cais tawm.
C) ib leeg-valve cais tawm ntxiv ntxiv rau cov neeg dig muag phaj, uas yog, ib qho kev sib cais valve siv los kaw qhov hluav taws xob sab hauv thiab tawm ntawm cov cuab yeej, cov chaw thiab cov khoom siv, thiab qhov nruab nrab hauv cov raj xa dej yog txo kom pab txhawb qhov nkag ntawm cov phaj dig muag. ua tiav lub hom phiaj kawg ntawm kev rho tawm khoom. Haum rau kev rho tawm ntawm cov nruab nrab nruab nrab xws li dej hiav txwv muaj qhov dej siab siab (> 1.7mpa) thiab cov yeeb nkab tsis loj; Kev rho tawm cov kua hluav taws xob, roj cua thiab cov pa roj lom muaj kuab paug tsis muaj yeeb nkab siab lossis kev txwv loj.
