Muaj cov tshuaj fluorinenpauj npaim valveyog ib hom lining valve feem ntau siv rau hauv cov kua qaub thiab alkali thiab lwm yam corrosive media. Nws tau siv dav hauv roj av, tshuaj lom neeg, tshuaj, metallurgy, hluav taws xob thiab lwm yam lag luam. Vim yog qhov nyuaj ntawm nws cov yam ntxwv ntawm cov qauv thiab qhov nyuaj ntawm cov ntaub ntawv lining muaj ntau haiv neeg, 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 valve uas muaj fluorine yog ib txheej yas qhwv rau ntawm qhov chaw ntawm lub cev valve uas ua los ntawm hlau cam khwb cia lossis stainless hlau thiab pawg valve ntawm lub disc uas sib cuag nrog cov kua dej. Lub hom phiaj ntawm kev xeb. Vim tias cov yas sib cuag nrog cov khoom nruab nrab, nws qhov nyuaj tsis zoo, thiab cov khoom nruab nrab siv yuav tsum tsis txhob muaj cov khoom tawv, siv lead ua, cov khoom tsis huv, thiab lwm yam, kom tiv thaiv lub valve kom tsis txhob hnav lub plawv valve, txheej fluorine ntawm lub rooj zaum valve lossis txheej fluorine thaum lub sijhawm qhib thiab kaw lub valve. Fluorine bellows. Rau cov khoom nruab nrab uas muaj cov khoom tawv, siv lead ua thiab cov khoom tsis huv, thaum xaiv, lub plawv valve thiab lub rooj zaum valve tuaj yeem xaiv los ntawm cov hlau tsis xeb, xws li INCONEL, MONEL, Hastelloy, thiab lwm yam.
2. Qhov kub ntawm cov khoom siv uas siv los ntawm lub valve uas muaj fluorine: cov yas fluorine siv yog F46 (FEP), thiab qhov kub ntawm cov khoom siv tsis pub tshaj 150 ° C (qhov kub ntawm cov khoom siv tuaj yeem ncav cuag 150 ° C hauv lub sijhawm luv luv, thiab qhov kub yuav tsum tau tswj hwm hauv 120 ° C rau lub sijhawm ntev) Txwv tsis pub, F46 daim ntaub ntawm cov khoom siv valve yooj yim ua kom mos thiab deform, ua rau lub valve kaw tsis zoo thiab xau loj. Yog tias qhov kub ntawm cov khoom siv siv qis dua 180 ℃ rau lub sijhawm luv luv thiab qis dua 150 ℃ rau lub sijhawm ntev, lwm cov fluoroplastic tuaj yeem siv.
-PFA, tab sis PFA uas muaj fluoroplastics kim dua li F46 uas muaj.
3. Qhov siab thiab qhov sib txawv ntawm lub siab yuav tsum tau tswj kom nyob rau hauv qhov ntau uas tso cai. Yog tias qhov sib txawv ntawm lub siab thiab lub siab loj dhau, nws yooj yim ua rau lub foob puas thaum lub sijhawm qhib thiab kaw ntawm lub valve, uas yuav cuam tshuam rau kev ua haujlwm ntawm lub valve.
4. Ntau hom tshuaj corrosive media feem ntau tsis yog ib hom kua qaub, alkali, thiab ntsev xwb. Qhov no ua rau nws nyuaj rau xaiv cov khoom siv hauv pem teb kom haum, uas xav tau kev xaiv ntau yam xws li qhov sib piv ntawm cov kua, qhov concentration, qhov kub ntawm nruab nrab, qhov loj ntawm cov khoom me me, thiab qhov nrawm ntawm cov khoom me me.
5. Lub valve uas muaj fluorine-lined butterfly yuav tsum tau xaiv kom raug raws li qhov ntws uas xav tau (Cv tus nqi). Tus nqi CV ntawm lub valve uas muaj fluorine-lined butterfly yog me dua li ntawm lub valve wafer butterfly thiab flange butterfly valve. Thaum xaiv, lub cheeb thiab qib qhib ntawm lub valve uas muaj fluorine-lined butterfly yuav tsum tau xam raws li qhov ntws uas xav tau (Cv tus nqi) thiab lwm yam kev ntsuas. Yog tias lub cheeb ntawm lub valve raug xaiv loj dhau, nws yuav ua rau lub valve qhib ntev. Kev ua haujlwm hauv cov xwm txheej me me, ua ke nrog lub siab ntawm cov khoom nruab nrab, yuav yooj yim ua rau lub plawv valve thiab pas nrig raug cuam tshuam los ntawm cov khoom nruab nrab kom ua rau lub valve co. Lub plawv valve pas nrig yuav tawg txawm tias nyob rau hauv qhov cuam tshuam ntawm cov khoom nruab nrab rau lub sijhawm ntev. Thaum xaiv ntau hom valve uas muaj fluorine-lined, cov neeg siv yuav tsum nkag siab thiab nkag siab txog cov xwm txheej kev siv ntau li ntau tau, kom lawv tuaj yeem xaiv thiab siv tau zoo, thiab lub neej ua haujlwm ntawm lub valve tuaj yeem txhim kho. Yog tias siv ntau tshaj qhov yuav tsum tau ua, yuav tsum tau muab rau tus neeg tsim khoom, sib tham ua ke, thiab siv cov kev daws teeb meem los daws qhov teeb meem no. 6. Tsis txhob siv lub siab tsis zoo. Lub valve uas muaj fluorine yuav tsum tsis txhob siv lub siab tsis zoo hauv cov kav dej. Yog tias muaj lub siab tsis zoo, txheej fluorine hauv lub qhov sab hauv ntawm lub valve yuav raug nqus tawm (bulged) thiab raug plhaub, uas yuav ua rau lub valve qhib thiab kaw kom tsis ua haujlwm.
