Yuav xaiv txoj cai li casphau ntawv npauj npaim valvesealing khoom?
Phau ntawv npauj npaim li qub yog ib hom valve, feem ntau yog siv rau kev khiav dej num thiab tswj cov dej hauv cov kav dej. Cov khoom siv sealing ua lub luag haujlwm tseem ceeb hauv kev sib khi ua haujlwm ntawm phau ntawv npauj npaim valve, yog li thaum xaiv lub valve, nws yog ib qho tsim nyog yuav tsum nkag siab txog kev ua tau zoo thiab kev siv ntau yam ntawm cov khoom sib txuas sib txawv txhawm rau xaiv cov khoom tsim nyog npauj npaim valve sealing khoom.
1. Fluorine roj hmab (FKM)
fluorine roj hmab muaj cov tshuaj tiv thaiv zoo thiab cov khoom kub kub, thiab tuaj yeem tsim lub foob zoo dua ntawm qhov kub thiab txias. Haum rau cov kua xov xwm uas muaj cov kua qaub, alkalis, roj thiab oxidants. Txawm li cas los xij, cov khoom siv roj hmab fluorine sealing yog kim dua thiab tsis haum rau kev siv nyob rau hauv chav dej.
2.NBR roj hmab
Qhov zoo ntawm NBR roj hmab sealing cov ntaub ntawv yog tus nqi qis thiab kev ua haujlwm ruaj khov. Txawm li cas los xij, nws qhov kub thiab txias tsis kam, oxidation tsis kam thiab corrosion kuj tsis muaj zog, feem ntau haum rau cov ntawv thov me me thiab nruab nrab qis xws li dej, roj, chav thiab hlau brine.
3. Neoprene roj hmab (CR)
Neoprene muaj cov roj ua haujlwm zoo thiab tiv thaiv kev laus, thiab tuaj yeem siv ntau qhov kub thiab txias. Haum rau cov roj, chlorinated carbon thiab lwm cov kuab tshuaj nruab nrab ib puag ncig, tab sis tsis haum rau qhov kub kub ib puag ncig.
4. Silicone Roj Hmab (Si)
Silicone roj hmab sealing khoom muaj qhov kub thiab txias tsis kam, hluav taws xob tiv thaiv thiab poob siab thiab tawg tsis kam, haum rau sealing nyob rau hauv ib puag ncig kub. Txawm li cas los xij, qhov elasticity thiab kua muag tsis kam ntawm silicone roj hmab nyob rau hauv qhov kub thiab txias ib puag ncig yog qhov tsis zoo.
5. PTFE
Qhov zoo ntawm PTFE yog tias nws muaj kev tiv thaiv zoo corrosion thiab kub tsis kam, tab sis nws elasticity thiab hnav tsis kam yog qhov tsis zoo, thiab nws tsis haum rau kev siv hauv cov dej ib puag ncig nrog cov nqi nrawm.
6. Polyimide (PI)
Polyimide yog ib hom kub thiab siab zog yas khoom, nrog rau kev ua tau zoo ntawm qhov kub thiab txias thiab zoo heev corrosion kuj, haum rau kub thiab siab kub ib puag ncig raws li ib tug sealing khoom.
Thaum xaiv ib phau ntawv npauj npaim valve sealing khoom, nws yog ib qho tsim nyog yuav tsum xav txog qhov xwm txheej ntawm cov dej hauv cov kav dej, tus nqi ntws, kub, siab thiab lwm yam, thiab xaiv cov khoom sib khi tsim nyog los xyuas kom meej qhov kev ua haujlwm ruaj khov thiab kev nyab xeeb ntawm phau ntawv. npauj npaim valve. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ua ntej siv cov khoom sib khi, nws raug nquahu kom sim nws cov kav ntev thiab sealing kev ua tau zoo hauv lub hom phiaj ntawm cov kua dej.
