Fluorine-linednpauj npaim valveyog ib hom kab hauv ob sab phlu feem ntau siv hauv cov kua qaub thiab alkali thiab lwm yam corrosive media.Nws tau dav siv hauv roj av, tshuaj, tshuaj, metallurgy, hluav taws xob fais fab thiab lwm yam lag luam.Vim yog qhov nyuaj ntawm nws cov yam ntxwv ntawm cov qauv thiab qhov nyuaj ntawm cov ntaub ntawv hauv ob sab phlu Diversity, feem ntau cov neeg siv tsis paub yuav pib xaiv li cas, tsab xov xwm no yuav qhia txog yuav ua li cas xaiv fluorine-lined npauj npaim valve.
1. Lub fluorine-lined npauj npaim valve yog ib txheej ntawm cov yas qhwv rau saum npoo ntawm cov cam khwb cia hlau los yog stainless hlau valve lub cev thiab lub valve pawg ntawm cov disc uas nyob rau hauv kev sib cuag nrog cov kua.Lub hom phiaj ntawm corrosion.Txij li cov yas yog nyob rau hauv kev sib cuag nrog nruab nrab, nws hardness yog tsis zoo, thiab qhov nruab nrab siv yuav tsum tsis txhob muaj ib tug nyuaj hais, muaju, impurities, thiab lwm yam, thiaj li yuav tiv thaiv lub valve los ntawm hnav tawm lub valve core, fluorine-lined txheej. ntawm lub rooj zaum valve lossis txheej fluorine thaum lub sijhawm qhib thiab kaw ntawm lub valve.Fluorine nqus.Rau qhov nruab nrab nrog cov khoom nyuaj, muaju thiab impurities, thaum xaiv, lub valve tseem ceeb thiab lub rooj zaum valve tuaj yeem xaiv los ntawm corrosion-resistant alloys, xws li INCONEL, MONEL, Hastelloy, thiab lwm yam.
2. Qhov kub ntawm qhov nruab nrab siv los ntawm fluorine-lined npauj npaim valve: fluorine yas siv yog F46 (FEP), thiab qhov kub ntawm qhov nruab nrab siv tsis tuaj yeem tshaj 150 ° C (qhov kub ntawm qhov nruab nrab tuaj yeem ncav cuag 150 ° C hauv lub sij hawm luv luv, thiab qhov kub thiab txias yuav tsum tswj tsis pub dhau 120 ° C rau lub sijhawm ntev) Txwv tsis pub, F46 hauv ob sab phlu ntawm lub valve yog ib qho yooj yim rau soften thiab deform, ua rau lub valve kaw undeadly thiab loj to.Yog tias qhov kub ntawm qhov nruab nrab siv qis dua 180 ℃ rau lub sijhawm luv luv thiab qis dua 150 ℃ rau lub sijhawm ntev, lwm cov fluoroplastic tuaj yeem siv tau.
-PFA, tab sis PFA lined nrog fluoroplastics yog kim dua F46 lined.
3. Lub siab thiab siab sib txawv yuav tsum tau tswj nyob rau hauv qhov kev tso cai.Yog tias lub siab thiab qhov sib txawv ntawm qhov sib txawv loj heev, nws yooj yim los ua kev puas tsuaj rau lub foob thaum lub sijhawm qhib thiab kaw lub valve, uas yuav cuam tshuam rau kev sib khi ntawm lub valve.
4. Ntau hom kev lag luam corrosive media feem ntau tsis yog tib hom kua qaub, alkali, thiab ntsev.Qhov no ua rau nws nyuaj rau xaiv cov khoom siv hauv ob sab phlu uas tsim nyog, uas yuav tsum muaj kev xaiv dav dav xws li cov kua muaj pes tsawg leeg, concentration, nruab nrab kub, particle loj, thiab ntws tus nqi nruab nrab.
5. Lub fluorine-lined npauj npaim valve yuav tsum raug xaiv kom raug raws li qhov yuav tsum tau muaj tus nqi ntws (Cv tus nqi).Tus nqi CV ntawm lub fluorine-lined npauj npaim valve yog me ntsis me dua li ntawm qhov zoo tib yam wafer npauj npaim valve thiab flange npauj npaim valve.Thaum xaiv, txoj kab uas hla thiab qhib degree ntawm fluorine-lined npauj npaim valve yuav tsum tau xam raws li qhov yuav tsum tau txaus tus nqi (Cv tus nqi) thiab lwm yam kev tsis.Yog tias txoj kab uas hla ntawm lub valve raug xaiv loj heev, nws yuav ua rau lub valve qhib rau lub sijhawm ntev.Kev ua haujlwm nyob rau hauv cov xwm txheej me me, ua ke nrog lub siab ntawm qhov nruab nrab, yuav yooj yim ua rau lub valve core thiab pas nrig cuam tshuam los ntawm qhov nruab nrab ua rau lub valve vibrate.Lub valve tub ntxhais pas nrig yuav txawm tawg nyob rau hauv qhov kev cuam tshuam ntawm qhov nruab nrab ntev.Thaum xaiv ntau hom fluorine-lined li qub, cov neeg siv yuav tsum nkag siab thiab tuav cov txheej txheem kev siv ntau li ntau tau, kom lawv tuaj yeem xaiv thiab siv tau zoo, thiab kev pabcuam lub neej ntawm lub valve tuaj yeem txhim kho.Nyob rau hauv qhov kev tshwm sim ntawm ntau tshaj qhov kev siv ntawm tej yam kev mob rau kev siv, nws yuav tsum tau thov mus rau lub chaw tsim tshuaj paus, kev sib tham ua ke, thiab tau txais yuav coj countermeasures los daws nws.6. Zam kev tsis zoo siab.Lub fluorine-lined valve yuav tsum tsis txhob siv qhov tsis zoo siab hauv cov kav dej.Yog tias muaj qhov tsis zoo, cov fluorine-txheej txheej hauv cov kab noj hniav sab hauv ntawm lub valve yuav raug nqus tawm (bulged) thiab plhaub, uas yuav ua rau lub valve qhib thiab kaw ua haujlwm tsis zoo.
