Lub pob valve mos thiab lub foob tawv

1. Qhov txawv tseem ceeb ntawmlub valve npauj npaim mos mosthiab lub valve npauj npaim kaw ruaj khov?

Cov khoom siv ntawm lub nplhaib sib khi yog txawv. Lub khub sib khi ntawm lub valve mos-sealing yog "lub rooj zaum hlau + lub nplhaib sib khi tsis yog hlau", thiab cov ntaub ntawv siv feem ntau suav nrog roj hmab (EPDM / NBR), polytetrafluoroethylene (PTFE), thiab lwm yam, raws li pom hauv Daim Duab 01; lub khub sib khi ntawm lub valve tawv-sealing yog "hlau rau hlau", thiab lub rooj zaum valve thiab qhov chaw sib khi feem ntau yog ua los ntawm cov hlau tsis xeb, hlau alloy lossis carbide surfacing. Tus thawj zaug ua tiav kev sib khi los ntawm kev hloov pauv elastic ntawm cov khoom siv, thaum tus kawg vam khom kev ua haujlwm raug thiab qhov siab nruab nrab kom ua tiav kev sib khi.

2. Qhov kub thiab txias uas siv tau ntawm txhua tus yog dab tsi?

Cov foob mos tsuas yog siv rau cov khoom siv uas tsis yog hlau xwb: roj hmab EPDM siv tau rau -40 ℃ ~ 120 ℃, thiab PTFE siv tau txog -40 ℃ ~ 200 ℃. Tsis muaj kev txwv rau cov foob tawv. Cov foob pob hluav taws uas siv cov hlau tsis xeb ib txwm siv tau rau -40 ℃ ~ 425 ℃, thiab cov khoom siv hlau tshwj xeeb tuaj yeem tiv taus qhov kub siab tshaj 600 ℃.

3. Qhov kev ua haujlwm sealing twg zoo dua?

Lub foob mos mos zoo dua thiab tuaj yeem ua tiav xoom qhov xau (ANSI Class VI). Lub elasticity ntawm roj hmab / PTFE tuaj yeem sau qhov tsis sib xws me me ntawm qhov chaw hlau thiab ua tiav qhov sib khi ua npuas. Vim yog qhov sib cuag ntawm cov hlau, cov qauv kev cai ntawm cov foob tawv feem ntau yog ANSI Class IV ~ V (tso cai xau tsawg kawg nkaus), uas yog qhov tsim nyog rau cov txheej txheem xov xwm uas muaj qee qhov kev kam rau xau.

4. Qhov txawv ntawm lub neej ua haujlwm thiab cov nqi txij nkawm yog dab tsi?

Cov foob pob zeb tawv muaj zog dua. Cov roj hmab mos-sealing/PTFE nplhaib yooj yim hnav thiab laus vim yog kev yaig mus sij hawm ntev thiab kev hloov pauv ntau zaus. Lub nplhaib foob feem ntau yuav tsum tau hloov txhua 2 txog 5 xyoos. Tom qab cov hlau nplaum tawv raug txau-welded nrog carbide, nws tiv taus kev hnav thiab yaig, thiab muaj lub neej ua haujlwm ntau dua 10 xyoo. Nws yog qhov tsim nyog rau kev hloov kho ntau zaus ntawm cov xwm txheej ua haujlwm. Txawm hais tias tus nqi pib siab, tus nqi txij nkawm mus sij hawm ntev qis dua.

5. Kev hloov kho ntawm xov xwm sib txawv li cas?

Lub foob mos mos tsis tiv taus cov khoom siv corrosion/particle uas muaj zog. Txawm hais tias roj hmab thiab PTFE muaj kev ruaj khov tshuaj zoo, yog tias cov khoom siv muaj cov khoom tawv (xws li slurry, thee hmoov), cov khoom me me tuaj yeem yooj yim khawb qhov chaw mos mos thaum lub valve qhib thiab kaw, ua rau xau. Cov foob tawv yog qhov tsim nyog rau cov xwm txheej ua haujlwm hnyav xws li cov pa kub siab, cov khoom siv roj, cov slurries uas muaj cov khoom me me, thiab cov pa roj siab.

Qhov sib txawv tseem ceeb ntawm lub foob mos thiab lub foob tawv ntawm lubnpauj npaim valveNyob rau hauv cov khoom siv sealing: lub foob mos (roj hmab / PTFE) muaj qhov elasticity zoo, tuaj yeem ua tiav xoom qhov xau, thiab tsim nyog rau cov khoom siv huv ntawm chav tsev kub; lub foob tawv (hlau rau hlau) yog qhov kub siab tiv taus thiab hnav-resistant, thiab tsim nyog rau cov xwm txheej ua haujlwm hnyav xws li pa thiab cov khoom me me. Ob leeg muaj lawv tus kheej qhov zoo, thiab kev xaiv yuav tsum tau ua raws li cov xwm txheej ua haujlwm.Tiv tauj peb - ​​Tianjin Tanggu Water-Seal Valve Co., Ltdtshwj xeeb hauv kev tsim khoom ntawmnpauj npaim li qub, lub qhov rooj vag, xyuas cov li qubthiab lwm hom li qub.
