Kev tiv thaiv kev ntsuas thaum txhim kho li qub Kev ua haujlwm tsis tu ncua ntawm fluorine lined anticorrosive li qub

 
Thaum lub valve raug teeb tsa, tus neeg siv yuav tsum tsis txhob nkag siab nws txoj kev teeb tsa, vim tias lub valve raug teeb tsa thaum kev tiv thaiv kuj tseem ceeb heev. Yog tias koj tsis xyuam xim thaum lub sijhawm teeb tsa, nws yooj yim ua rau kev puas tsuaj lossis xau ntawm lub valve, uas yuav ua rau muaj teeb meem ntau. Yog li yuav ua li cas tiv thaiv thaum txhim kho lub valve? Cov nram qab no Xiaobian yuav qhia tshwj xeeb txog kev tiv thaiv kev teeb tsa ntawm lub valve.
Kos lub valve tiv thaiv
Nyob rau hauv KEV PAB CUAM TSHUAJ TIV THAIV cov dej xau ntawm cov tshev valve lossis rov qab ntawm cov xov xwm tom qab tsis ua haujlwm, ua rau cov khoom lag luam poob qis, kev sib tsoo thiab lwm yam tsis zoo, ib lossis ob qhov kev txiav tawm valve tau teeb tsa ua ntej thiab tom qab kos valve. Yog tias muaj ob lub kaw-off li qub, cov tshev valve tuaj yeem raug tshem tawm yooj yim rau kev pabcuam.
Kev nyab xeeb valve tiv thaiv cov chaw
Kev txhim kho txoj kev ua ntej thiab tom qab qhov dav dav tsis txhob teeb tsa qhov kev faib tawm valve, tsuas yog nyob rau hauv ib qho xwm txheej, tuaj yeem siv tau. Yog hais tias lub zog nruab nrab muaj cov khoom siv, cuam tshuam rau kev nyab xeeb valve tsis tuaj yeem kaw tom qab tshem tawm, txhawm rau txhim kho lub qhov rooj kaw qhov rooj ua ntej thiab tom qab kev nyab xeeb valve, lub rooj vag valve yuav tsum nyob rau hauv lub xeev qhib tag nrho, lub rooj vag valve. thiab kev nyab xeeb valve ncaj qha nruab nrog DN20 tshuaj xyuas valve rau qhov chaw.
Thaum lub nyem ntawm wax thiab lwm yam xov xwm nyob rau hauv chav tsev kub rau cov khoom lub xeev, los yog txo lub siab gasification thiab thiaj li hais tias lub teeb kua nruab nrab kub hauv qab no 0 degrees Celsius, qhov kev nyab xeeb valve xav tau chav cua sov. Kev nyab xeeb valve rau corrosive xov xwm, nyob ntawm seb qhov corrosion kuj ntawm lub valve, xav txog kev ntxiv corrosion resistant explosion-proof zaj duab xis ntawm lub valve inlet. Gas kev ruaj ntseg valve feem ntau yog muab nrog lub bypass valve raws li nws qhov loj me, raws li phau ntawv qhov cua.
Cov cuab yeej tiv thaiv ntawm lub siab txo valve
Siab txo valve installation chaw feem ntau muaj peb daim ntawv. Cov ntsuas ntsuas siab tau teeb tsa ua ntej thiab tom qab lub valve txo kom yooj yim rau kev soj ntsuam lub siab ua ntej thiab tom qab lub valve. Muaj lub kaw lus ruaj ntseg tag nrho tom qab lub valve los tiv thaiv qhov tsis ua haujlwm ntawm lub siab txo valve, lub valve tom qab lub siab tshaj qhov qub siab thaum dhia, suav nrog lub valve tom qab lub kaw lus. Cov kav dej ntws tau muab tso rau hauv pem hauv ntej ntawm lub valve kom txiav tawm lub valve, lub luag haujlwm tseem ceeb yog txhawm rau tso dej ntws tawm, qee qhov siv lub ntxiab. Lub luag haujlwm tseem ceeb ntawm cov yeeb nkab bypass yog thaum lub siab txo valve tsis ua hauj lwm, kaw lub siab txo valve ua ntej thiab tom qab txiav tawm valve, qhib lub bypass valve, manually kho cov ntws, ua si ib ntus ncig lub luag hauj lwm, thiaj li yuav kho lub bypass valve. siab txo valve los yog hloov lub siab txo valve.
Cov cuab yeej cuab tam tiv thaiv
Muaj ob hom ntxiab nrog bypass yeeb nkab thiab tsis muaj bypass yeeb nkab nyob rau sab ntawm lub ntxiab, condensate rov qab thiab condensate tsis rov qab them nyiaj, tso tawm thiab lwm yam tshwj xeeb uas yuav tsum tau ntawm lub ntxiab, tuaj yeem ntsia tau rau tib lub sijhawm.
Lub ntxiab nrog bypass valve feem ntau yog siv los tso tawm ntau cov dej condensed thaum lub raj xa dej pib khiav. Thaum SERVICING TRAP, nws tsis tsim nyog rau DRAIN CONDENSATE los ntawm ib qho BYPASS yeeb nkab, uas tuaj yeem ua rau lub zog khiav mus rau hauv LUB ROOJ ROOJ SYSTEM. Nyob rau hauv ib txwm muaj xwm txheej, tsis txhob nruab bypass yeeb nkab. Tsuas yog thaum cov cua kub yog nruj me ntsis yuav tsum tau, cov khoom siv thermal rau kev tsim khoom tas li yuav tsum tau nruab nrog cov yeeb nkab bypass.
Kev ua haujlwm tsis tu ncua ntawm fluorine lined anticorrosive valve
1, fluorine lined yas valve nruab nrab kub: Peb lub tuam txhab muaj ntau hom fluorine lined yas li qub, kev siv fluorine yas yog F46 (FEP), kev siv nruab nrab kub tsis tshaj 150 ℃ (qhov nruab nrab kub yuav yog 150 ℃ rau luv luv. lub sij hawm, lub sij hawm ntev siv kub yuav tsum tau tswj nyob rau hauv 120 ℃), txwv tsis pub, lub valve Cheebtsam nyob rau hauv F46 yooj yim mus soften, deformation, ua rau lub valve kaw undead, loj to.
Yog tias qhov kub ntawm qhov nruab nrab siv qis dua 180 ℃ rau lub sijhawm luv luv, thiab qhov kub thiab txias qis dua 150 ℃ rau lub sijhawm ntev, lwm hom fluorine yas tuaj yeem xaiv tau; PFA, tab sis lined nrog PFA fluorine yas yog kim dua lined nrog F46 hauv nqe.
2, tsis txhob muaj lub siab tsis zoo. fluorine lined yas valve yuav tsum tsis txhob siv lub siab tsis zoo hauv cov raj xa dej, yog tias muaj qhov tsis zoo, yooj yim ua rau cov fluorine lined yas txheej hauv lub valve kab noj hniav yog nqus tawm (nruas tawm), tev, ua rau lub valve qhib thiab kaw tsis ua haujlwm. .
3, lub siab, siab sib txawv yuav tsum tau tswj nyob rau hauv lub permissible ntau yam. Tshwj xeeb tshaj yog bellows foob lined fluorine yas regulating valve, ntiaj teb valve. Vim hais tias lub hauv paus yog ua los ntawm cov ntaub ntawv tetrafluoric, lub siab thiab siab sib txawv yog qhov loj, uas tuaj yeem yooj yim ua rau lub hauv siab tawg.
Bellows seal lined fluorine yas regulating valve, kev siv cov mob siab, siab sib txawv loj, tuaj yeem hloov mus rau PTFE packing seal.
4. Qhov nruab nrab ntawm fluorine lined yas valve yuav tsum tsis txhob muaj cov khoom nyuaj, muaju, impurities, thiab lwm yam, kom tsis txhob hnav tawm lub valve core thiab valve lub rooj zaum lined fluorine yas txheej los yog PTFE bellows nyob rau hauv lub lag luam ntawm qhib thiab kaw. Qhov nruab nrab muaj cov khoom nyuaj, muaju, impurities, xaiv, spool, rooj zaum siv tau rau Hastelloy.
5, lined nrog fluorine yas regulating valve yuav tsum tau raws li qhov yuav tsum tau txaus (Cv tus nqi) raug xaiv ntawm valve txoj kab uas hla loj. Thaum xaiv, yuav tsum tau raws li qhov xav tau ntawm kev khiav tsheb (Cv) thiab lwm yam kev ntsuas tsis suav nrog lub valve loj yuav tsum tau xaiv thiab qhib lub valve, xws li valve qhov loj heev, yeej yuav ua rau lub valve qhib rau ntev. lub sij hawm khiav, nyob rau hauv cov xwm txheej ntawm me me thiab nruab nrab siab, yog li yooj yim ua rau lub valve core thiab valve qws los ntawm kev cuam tshuam ntawm cov xov xwm thiab ua rau lub valve vibrates, lub valve core pas nrig nyob rau hauv nruab nrab rau ib tug ntev lub sij hawm nyob rau hauv kev cuam tshuam, txawm yuav ua rau lub valve qia puas.
