Fluoroplastic lined corrosion-resistant npauj npaim valveyog muab polytetrafluoroethylene resin (los yog profile ua tiav) rau sab hauv phab ntsa ntawm cov hlau los yog hlau npauj npaim valve siab-cov kabmob qhov chaw lossis sab nrauv ntawm npauj npaim valve sab hauv los ntawm molding (los yog inlay). Cov khoom tshwj xeeb ntawm npauj npaim li qub tiv thaiv cov xov xwm muaj zog corrosive yog ua rau ntau hom npauj npaim li qub thiab cov hlab ntsha siab.
Hauv cov khoom siv los tiv thaiv corrosion, PTFE muaj qhov ua tau zoo heev. Ntxiv rau molten hlau, elemental fluorine thiab aromatic hydrocarbons, nws yuav siv tau nyob rau hauv ntau yam concentrations ntawm hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid, muaj zog oxidant, concentrated, alternating dilute acid, alternating alkali thiab ntau yam organic agents. yog random tshuaj. Hauv ob sab phlu PTFE rau sab hauv phab ntsa ntawm npauj npaim valve tsis tsuas yog overcomes lub shortcomings ntawm tsis muaj zog ntawm PTFE khoom, tab sis kuj daws qhov teeb meem ntawm corrosion kuj ntawm npauj npaim valve ntsiab cov ntaub ntawv. Kev ua haujlwm tsis zoo thiab tus nqi siab. Tsis tas li ntawd, ntxiv rau nws cov tshuaj lom neeg ruaj khov zoo heev, PTFE muaj cov khoom zoo antifouling thiab anti-stick, tsis tshua muaj me me dynamic thiab zoo li qub kev sib txhuam coefficients, thiab zoo tiv thaiv kev sib txhuam thiab lubrication kev ua tau zoo. Nws yog siv los ua khub sealing rau qhib thiab kaw ntawm npauj npaim li qub, thiab nws yog ib qho tsim nyog los txo qhov sealing nto. Kev sib txhuam ntawm npauj npaim li qub tuaj yeem txo qis, kev ua haujlwm torque ntawm npauj npaim valve tuaj yeem txo, thiab kev pabcuam lub neej ntawm cov khoom tuaj yeem txhim kho.
Fluorine-lined npauj npaim valve, tseem hu ua anti-corrosion npauj npaim valve, feem ntau yog siv nyob rau hauv hnyav ua hauj lwm tej yam kev mob, xws li tshuaj lom thiab teeb meem tshuaj, los yog heev corrosive ntau yam acid-base los yog organic solvents. Kev siv tsis raug yuav ua rau muaj kev poob nyiaj txiag loj thiab loj heev vim qhov tshwm sim ntawm. Kev siv thiab kev saib xyuas ntawm tus npauj npaim valve tuaj yeem ua rau lub neej ntev ntawm cov fluorine-lined npauj npaim valve, yog li cov ntsiab lus twg tuaj yeem ua tau los tiv thaiv nws zoo?
1. Ua ntej siv, ua tib zoo nyeem phau ntawv qhia ntawm fluorine-lined butterfly valve.
2. Siv nws nyob rau hauv qhov ntau ntawm qhov siab, qhov kub thiab qhov nruab nrab tau teev tseg rau ntawm daim ntawv teev npe lossis hauv phau ntawv.
3. Thaum siv, tiv thaiv cov fluorine-lined npauj npaim valve los ntawm kev tsim cov kav dej ntau dhau vim qhov kub thiab txias hloov, txo qhov kub thiab txias hloov, thiab ntxiv U-shaped expansion pob qij txha ua ntej thiab tom qab npauj npaim valve.
4. Nws yog txwv tsis pub siv lub zog qhib thiab kaw lub fluorine-lined npauj npaim valve. Ua tib zoo saib xyuas qhov qhib thiab kaw qhov taw qhia thiab txwv cov cuab yeej ntawm fluorine-lined npauj npaim valve. Tom qab qhib thiab kaw nyob rau hauv qhov chaw, tsis txhob yuam lub valve kom kaw, kom tsis txhob muaj kev puas tsuaj ntxov rau lub fluorine yas sealing nto.
5. Rau qee qhov kev tshaj tawm uas tsis ruaj khov thiab yooj yim rau decompose (piv txwv li, qhov decomposition ntawm qee qhov xov xwm yuav ua rau lub ntim nthuav dav thiab ua rau lub siab txawv txav hauv kev ua haujlwm), uas yuav ua rau npauj npaim valve puas lossis xau, ntsuas yuav tsum tau ua kom tshem tawm. los yog txwv cov yam uas ua rau decomposition ntawm cov xov xwm tsis ruaj khov. . Thaum xaiv ib lub npauj npaim valve, lub fluorine-lined npauj npaim valve nrog lub tshuab tsis siv neeg siab nyem yuav tsum raug xaiv los ntawm kev xav txog cov kev hloov pauv hauv kev ua haujlwm uas tshwm sim los ntawm qhov tsis ruaj khov thiab yooj yim decomposition ntawm nruab nrab.
6. Raufluorine-lined npauj npaim valvenyob rau hauv cov kav dej nrog tshuaj lom, flammable, explosive thiab muaj zog corrosive nruab nrab, nws yog nruj me ntsis txwv tsis pub hloov lub packing nyob rau hauv siab. Txawm hais tias fluorine-lined npauj npaim valve muaj lub siab sealing muaj nuj nqi hauv kev tsim, nws tsis pom zoo kom hloov cov ntim hauv siab.
7. Rau cov kav dej uas muaj qhov nruab nrab ntawm kev sib xyaw ua ke, yuav tsum ntsuas kom ntseeg tau tias qhov kub thiab txias ntawm qhov chaw ua haujlwm tsis tuaj yeem siab tshaj qhov sib txawv ntawm qhov nruab nrab los tiv thaiv kev phom sij los ntawm tshav ntuj lossis hluav taws kub sab nraud.
Qhov nruab nrab siv tau: ntau yam ntawm cov kua qaub-puag ntsev thiab qee cov kuab tshuaj organic.
