gate valve hom rooj vag: Vim li cas Feem Ntau Cov Kws Ua Haujlwm Xaiv Tsis Ncaj Ncees Hauv Ntawm -Qhov Chaw Ua Haujlwm

Raws li tus kws tshaj lij valve nrog 12 xyoo ntawm kev paub, Kuv tau pom suav tsis txheeb ntawm - qhov chaw ua tsis tiav los ntawm kev xaiv tsis raugrooj vag valve hom rooj vag-xws li sealing to, nyuaj hauv kev ua haujlwm cuam tshuam rau kev tsim khoom, lossis tseem ua rau tag nrho lub valve lub neej ua haujlwm luv.

 

Qhov tseeb, ntau tus neeg muaj kev xav tsis zoo txog hom rooj vag. Nws tsis yog qhov kim dua, qhov zoo dua; tus yuam sij yog nyob rau hauv kev sib piv cov kev ua hauj lwm tej yam kev mob.

 

Feem ntau cov teeb meem valve ntsib ntawm - qhov chaw yog ib nrab vim kev teeb tsa tsis raug thiab lwm qhov ib nrab vim xaiv qhov rooj tsis raug. Niaj hnub no, raws li kuv cov kev paub dhau los thiab kev tshawb fawb los ntawm cov ntawv xov xwm kev lag luam thoob ntiaj teb, kuv yuav piav qhia meej txog hom rooj vag valve. Txawm hais tias koj yog ib tug novice lossis ib tus neeg ua haujlwm ua haujlwm, koj tuaj yeem zam kev xaiv qhov teeb meem tom qab nyeem qhov no.

 

Ua ntej, cia peb tsim kom muaj kev nkag siab yooj yim. Lub rooj vag yog lub luag haujlwm tseem ceeb rau kev qhib / kaw thiab sib khi hauv lub rooj vag valve. Cov txheej txheem kev faib tawm rau lub rooj vag valve hom yog yooj yim: nws tsuas yog nyob ntawm seb tus qauv yog nruj los yog hloov tau, thiab seb daim ntawv sealing yog wedge los yog parallel.

 

Ntawm no, kuv yuav tsum hais txog cov qauv kev lag luam. Txawm hais tias xaiv hom twg, nws yuav tsum ua raws li API 600 thiab ANSI B16.34 cov cai, tshwj xeeb tshaj yog rau petrochemical thiab siab - cov xwm txheej siab. Ob tus qauv no yog lub hauv paus; uas ploj lawm tuaj yeem ua rau muaj teeb meem yav tom ntej. Qhov no yog qhov kev pom zoo tau hais tseg hauv tsab ntawv tshaj tawm 2024 los ntawmValve ntiaj tebmagazine.

 

Ua ntej, cia peb tham txog qhov feem ntau siv nruj ib lub rooj vag. Hom no yog integrally nrum nrog tsis muaj ntxiv compensating Cheebtsam. Nws muaj kev ntseeg siab heev hauv kev xyaum thiab tsim nyog rau qis - siab, qhov kub thiab txias, xws li cov kav dej dav dav thiab qis - cov kab cua siab.

 

Txawm li cas los xij, nws muaj qhov pom tseeb qhov tsis zoo: tsis zoo tiv thaiv deformation. Yog tias siv nyob rau hauv siab -siab lossis qhov kub thiab txias- qhov chaw hloov pauv, xws li cov kav dej nkev, nws yog qhov ua rau lub qhov rooj deformation thiab sealing tsis ua haujlwm.

 

Kuv ib zaug tau tuav ib qhov project rau cov khoom noj khoom haus uas, kom yooj yim, nruj ib lub rooj vag raug xaiv. Tsis pub dhau rau lub hlis, cov dej xau tau tshwm sim, thiab txhua yam yuav tsum tau hloov pauv. Qhov no tsis tsuas yog ncua sijhawm ntau lawm tab sis kuj nce nqi.

 

Ntawm no, cia kuv cuam tshuam: qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov rooj vag valve hom yog lawv qhov tsis kam rau deformation thiab sealing nyiaj them peev xwm. Rigid rooj vag tsom rau durability thiab simplicity, thaum lub rooj vag hloov tau yooj yim yog tsim los hloov mus rau complex tej yam kev mob.

 

Tam sim no, cia peb tham txog cov rooj vag hloov tau yooj yim. Cov rooj vag no muaj lub voj voog ncig ntawm ntug, muab elasticity uas cia li them nyiaj rau deformation los ntawm qhov kub thiab txias. Qhov no yog qhov sib txawv tseem ceeb ntawm cov rooj vag nruj.

 

Raws li tsab ntawv ceeb toom 2024 hauvValve ntiaj teb, lub sealing them qauv ntawm cov rooj vag hloov tau zoo yoog tau rau siab -siab, kub- hloov pauv, xws li siab - siab siab cov roj av hauv cov nroj tsuag petrochemical thiab cov kav dej hauv cov fais fab nroj tsuag. Txawm li cas los xij, lawv tsis yog universal. Vim lawv cov qauv elastic, lawv yuav tsum tsis txhob siv rau hauv kev tshaj tawm nrog cov khoom tsis huv loj, vim tias cov khib nyiab tuaj yeem daig hauv qhov zawj, ua rau muaj teeb meem kev ua haujlwm. Tsis tas li ntawd, lawv cov nqi tsim khoom yog siab dua cov rooj vag nruj. Rau qhov tsawg - cov xwm txheej siab, xaiv lawv ntawm cov peev nyiaj nruj yog qhov tsis tsim nyog thiab khib nyiab.

 

Tom qab ntawd muaj ob lub rooj vag nruj. Hom no muaj ob lub rooj vag ywj pheej discs nrog lub npoo thaiv nyob nruab nrab. Thaum lub sijhawm ua haujlwm, qhov kev faib tawm quab yuam yog ntau yam sib xws, txo qhov kev pheej hmoo ntawm jamming. Hom no feem ntau siv nyob rau hauv nruab nrab - cov kev kub ntxhov hauv kev lag luam tshuaj.

 

Nws cov nyhuv sealing zoo dua li ntawm ib lub rooj vag nruj, tab sis kev tshem tawm thiab kev saib xyuas muaj teeb meem ntau dua. Ntxiv mus, yog tias qhov nruab nrab muaj impurities, lawv tuaj yeem yooj yim nkag mus ntawm ob lub discs, cuam tshuam rau kev sib khi.

 

Flow Controlphau ntawv journal hais tias kev pabcuam lub neej ntawm ob lub rooj vag nruj feem ntau yog nyob ntawm cov khoom siv ntawm cov npoo thaiv. Xaiv cov khoom tsim nyog tuaj yeem txuas nws lub neej los ntawm 3-5 xyoos piv rau ib lub rooj vag nruj. Qhov no yog ib qho tseem ceeb uas yuav tau xav txog thaum xaiv; tsis txhob tsom rau ntawm lub rooj vag nws tus kheej thaum saib xyuas cov khoom txhawb nqa.

 

Tom qab sib tham txog cov hom, cia kuv qhia qee qhov kev ua tau zoo ntawm lub rooj vag valve gate hom xaiv cov lus qhia, uas kuv tau sau los ntawm ntau xyoo ntawm - qhov kev paub ntawm qhov chaw. Junior engineers tuaj yeem xa mus rau lawv ncaj qha.

 

Ua ntej, rau qis-siab, qhov kub thiab txias ib txwm nrog cov xov xwm huv si, cov rooj vag ib leeg yog txaus thiab muab tus nqi zoo tshaj - kev ua tau zoo. Rau siab -siab, qhov kub thiab txias-hloov tej yam kev mob, ua qhov tseem ceeb ntawm cov rooj vag hloov tau yooj yim, zoo dua yog cov ua raws li API 600 tus qauv. Rau nruab nrab- cov xwm txheej siab nrog qee qhov impurities hauv xov xwm, cov rooj vag ob chav yog qhov kev xaiv zoo tshaj.

 

Tsis tas li ntawd, rau lub rooj vag valve hom rau kev siv siab, muaj ib qho tshwj xeeb: koj yuav tsum xaiv cov hlau - rooj vag hloov tau yooj yim. Mos- rooj vag zaum yuav ua rau muaj kev puas tsuaj nyob rau hauv siab thiab yuav tsum ua tau raws li qhov yuav tsum tau muaj kev ntsuas siab ntawm API 600 tus qauv. Kev ntsuas siab tsis txaus tuaj yeem ua rau muaj kev nyab xeeb.

 

Kuv nco qab txog ib txoj haujlwm petrochemical uas cov mos- zaum rooj vag hloov tau raug xaiv, ua rau kev sib khi tsis ua haujlwm nyob rau hauv lub siab siab thiab cov roj crude to. Hmoov zoo, nws tau tshawb pom nyob rau lub sijhawm, tiv thaiv kev poob ntau dua.

 

Kuj tseem muaj ob peb qhov kev xaiv ntau yam uas txhua tus yuav tsum zam.

 

Thawj qhov pitfall yog qhov tsis meej pem cov kev thov siab ntawm cov rooj vag nruj thiab hloov tau yooj yim. Ntau tus neeg xav tias cov rooj vag hloov pauv tuaj yeem siv tau rau txhua qhov xwm txheej, tab sis qhov tsis muaj tseeb. Cov rooj vag yooj yim muaj qhov txwv siab tshaj plaws; Tshaj qhov kev txwv no yuav ua rau cov qauv elastic ua tsis tiav.

 

Qhov thib ob pitfall yog tsis quav ntsej qhov cuam tshuam ntawm kev tshaj tawm ntawm cov khoom siv rooj vag. Rau corrosive media, corrosion- cov ntaub ntawv rooj vag resistant yuav tsum raug xaiv; txwv tsis pub, lawv yuav corrode thiab perforate sai sai.

 

Qhov thib peb pitfall yog blindly nrhiav tus nqi siab, xav tias kim rooj vag valve rooj vag hom inherently zoo dua. Qhov no tsis yog li ntawd; kev tsim nyog rau kev ua haujlwm yog qhov tseem ceeb. Xaiv cov rooj vag hloov tau yooj yim rau qis - cov xwm txheej siab yog nkig nkaus xwb.

 

Raws li tus kws tshaj lij valve nrog 12 xyoo ntawm kev paub dhau los, kuv xav hais ntxiv tias tsis muaj qhov zoo lossis qhov tsis zoo ntawm lub rooj vag valve hom -tsuas yog qhov tsim nyog lossis tsis zoo. Txawm hais tias nruj los yog hloov tau, wedge los yog thaum uas tig mus, cov tub ntxhais yog txuam nrog rau ntawm - chaw ua hauj lwm tej yam kev mob thiab ua raws li cov qauv kev lag luam.

 

Raws liValve ntiaj tebcov lus ceeb toom, yav tom ntej qauv ntawm lub rooj vag valve hom yuav hloov mus rau kev tiv thaiv rau huab cua, yooj yim ntawm kev saib xyuas, thiab ncua kev pab cuam lub neej. Tshwj xeeb tshaj yog rau cov rooj vag siv nyob rau hauv sib sib zog nqus- hiav txwv, siab- kub, siab- ib puag ncig siab, yuav muaj kev tsom mus rau corrosion kuj thiab hnav tsis kam.

 

Thaum kawg, kuv rov hais dua: thaum xaiv hom rooj vag, tsis txhob saib qhov tsis zoo xwb. Kuj tseem xav txog qhov tseeb ntawm -qhov chaw nyob, nquag xa mus rau cov qauv kev lag luam thiab cov ntawv tshaj tawm hauv xov xwm, thiab sau cov kev paub dhau los kom tsis txhob muaj kev cuam tshuam thiab xaiv hom tsim nyog tshaj plaws. Tom qab tag nrho, hauv engineering, kev nyab xeeb thiab kev ruaj ntseg yog qhov tseem ceeb. Qhov yuam kev me me hauv kev xaiv hom rooj vag tuaj yeem ua rau muaj kev sib tsoo loj. Peb yuav tsum tsis txhob maj maj.

 

Kab lus no yog ua raws li API 600, ANSI B16.34 tus qauv, ua ke nrog 12 xyoo ntawm kev paub txog valve thiab cov ntsiab lus tshawb fawb los ntawmValve ntiaj tebthiabFlow Controlcov ntawv xov xwm, thiab yog npaj rau kev siv los ntawm kev lag luam engineers.
