2. Adaim ntawv thov nyob rau hauv kev ua hauj lwm sib txawv
Vim qhov sib txawv ntawm cov qauv, qeb A npauj npaim valve thiab qeb B npauj npaim valve kuj tau siv rau hauv kev ua haujlwm sib txawv.
2.1 Qeb A npauj npaim li qub tau siv dav hauv qhov tsis tshua muaj siab, txoj kab uas hla loj, xws li cov kav dej, qhov cua thiab lwm yam lag luam, vim nws cov qauv yooj yim, me me, lub teeb yuag thiab lwm yam nta.
2.2 Qeb B npauj npaim valve yog qhov tsim nyog rau daim ntawv thov ua haujlwm nrog kev ua haujlwm siab sealing thiab siab nruab nrab loj, xws li tshuaj lom neeg, roj av, roj thiab lwm yam lag luam.
3. Kev ua tau zoo sib piv
3.1 Sealing kev ua tau zoo: qeb B npauj npaim li qub feem ntau zoo dua li qeb A npauj npaim li qub hauv kev ua haujlwm sib khi, ua tsaug rau lawv cov qauv ntau dua thiab cov qauv foob ntxiv. Qhov no ua rau qeb B npauj npaim valve kom muaj kev sib khi zoo hauv qhov chaw hnyav xws li kev kub siab thiab kub.
3.2 Flow muaj peev xwm: Lub peev xwm txaus ntawm qeb Ib npauj npaim valve muaj zog, vim tias lub valve disk tsim yog qhov yooj yim, qhov tsis kam ntawm cov dej dhau los yog me me. Hom B npauj npaim valve tuaj yeem cuam tshuam qhov kev ua haujlwm ntawm cov kua dej rau qee yam vim nws txoj kev ua haujlwm nyuaj.
3.3 Durability: Lub durability ntawm qeb B npauj npaim li qub feem ntau yog siab dua, vim tias nws cov qauv tsim thiab xaiv cov khoom siv ntau dua rau kev ruaj ntseg mus ntev thiab corrosion kuj. Txawm hais tias qeb A npauj npaim valve yog qhov yooj yim hauv cov qauv, nws yuav ua rau muaj kev puas tsuaj rau qee qhov chaw hnyav.
4. Kev yuav khoom ceev faj
Thaum muas qeb A thiab qeb B npauj npaim li qub, cov hauv qab no yuav tsum tau xav txog:
4.1 Cov xwm txheej ua haujlwm: Xaiv cov pawg tsim nyog ntawm npauj npaim valve raws li lawv cov kev ua haujlwm siab, qhov kub thiab txias, nruab nrab thiab lwm yam kev mob ntawm cov kav dej. Piv txwv li, qeb B npauj npaim li qub yuav tsum tau muab qhov tseem ceeb hauv kev kub siab thiab kub ib puag ncig.
4.2 Cov kev xav tau ntawm kev ua haujlwm: Kev ua haujlwm kom meej meej, xws li yuav tsum tau qhib thiab kaw nrawm, ua haujlwm nquag thiab lwm yam, xaiv cov qauv npauj npaim valve tsim nyog thiab hom kev sib kis.
4.3 Economy: Raws li qhov ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm, xav txog kev lag luam ntawm tus npauj npaim valve, suav nrog cov nqi yuav khoom, tus nqi tu, thiab lwm yam., qeb A npauj npaim li qub feem ntau qis dua, thaum qeb B npauj npaim li qub, txawm tias zoo dua hauv kev ua tau zoo, kuj tseem yuav raug nqi siab.
