Npauj Npaim Valve Hom Lug Piav Qhia Vim Li Cas Nws Tseem Ceeb rau Kev Kho Kab Mob

Npauj Npaim Valve Lug Hom Piav Qhia: Vim Li Cas Nws Tseem Ceeb

Puas tau xav paub yuav ua li cas qee qhov chaw kho dej tuaj yeem kho cov khoom siv kav dej yam tsis muaj kev kaw haujlwm? Cov lus teb yog nyob rau hauv ib tug tshwj xeeb valve tsim.

 

Xav txog qhov xwm txheej no: lub chaw kho dej loj yuav tsum hloov lub twj tso kua mis rau ntawm lub raj xa dej. Ua raws li cov txheej txheem ib txwm ua, pab pawg saib xyuas yuav tsum kaw tag nrho cov kav dej, ntws ntau pua meters ntawm cov kav dej, thiab tsuas yog tom qab ntawd lawv tuaj yeem tshem tawm lub valve thiab hloov cov khoom siv. Cov txheej txheem no tsis yog tsuas yog lub sijhawm- siv xwb tab sis kuj txhais tau tias tag nrho cov kab ntau lawm yuav tsum nres, ua rau muaj kev poob nyiaj txiag loj.

 

Qhov no yog qhov tseeb vim li cas ntau thiab ntau tus engineers xaiv cov npauj npaim valve lug homnyob rau hauv qhov chaw tseem ceeb.

 

Dab tsi yog Npauj Npaim Valve Lug Hom thiab Nws Ua Haujlwm Li Cas?

A npauj npaim valve lug homyog lub valve uas tswj kev ntws los ntawm ib lub voj voog uas tig ib ncig ntawm lub ncej. Nws qhov tshwj xeeb tshwj xeeb yog ib txheej ntawm lugs cam khwb cia rau lub valve lub cev, txhua tus nrog threaded qhov, siv los bolt lub valve rau cov yeeb nkab flanges.

 

Thaum koj tig lub valve kov lossis actuator, lub disc tig ntawm 0 txog 90 degrees. Thaum lub disc yog sib npaug rau cov yeeb nkab, lub valve yog qhib tag nrho, tso cai rau cov xov xwm hla nrog kev cuam tshuam tsawg heev. Thaum lub disc tig mus rau ib qho perpendicular txoj hauj lwm, lub ntws yog kiag li kaw. Qhov kev tsim no tso cai rau covnpauj npaim valve lug homlos ua haujlwm ob qho tib si raws li qhov qhib / tawm valve thiab rau kev tswj hwm kev ntws.

 

Structurely, covnpauj npaim valve lug homyog qhov txawv ntawm cov wafer - hom npauj npaim valve. Lub wafer- hom valve yog clamped ntawm ob lub flanges los ntawm ntev mus txog -bolts. Piv txwv li, anpauj npaim valve lug hommuaj kev ywj pheej bolts ntawm txhua sab ruaj nws mus rau flanges. Qhov sib txawv no ua rau muaj qhov sib txawv ntawm daim ntawv thov scenarios.

 

Vim li cas npauj npaim Valve Lug Hom Lifesaver rau Engineers?

Rov qab mus rau qhov chaw kho dej hauv qhov chaw pib thaum pib: yog tias lub raj xa dej tau nruab nrog anpauj npaim valve lug hom, qhov xwm txheej yuav txawv kiag li.

 

Tus kws ua haujlwm tsuas yog yuav tsum kaw lub valve thiab tshem tawm cov bolts ntawm sab hauv qab kom tshem tawm cov yeeb nkab hauv qab thiab cov khoom siv kho. Lub ntsiab lus tseem ceeb yog tias txawm tias tom qab lub flange downstream raug tshem tawm, lub siab ntws tawm tseem ruaj ntseg kaw los ntawm lub cev.npauj npaim valve lug hom. Cov dej hauv cov kav dej yuav tsis xau, thiab cov dej ntws tuaj yeem ua haujlwm txuas ntxiv. Qhov peev xwm no paub hauv kev lag luam li "tuag-kev pabcuam kawg."

 

Rau cov cuab yeej tswj xyuas nquag xws li cov twj tso kua mis, cov ntxaij lim dej, thiab cov khoom siv hluav taws xob sib hloov, cov yam ntxwv no txhais tau tias txo qis qis dua. Yog tias koj npaj yuav 预留 kev txuas ntxiv txuas ntxiv rau yav tom ntej hauv lub raj xa dej, lossis xav tau qhov kawg txhim khu kev qha - ntawm - kab valve rau qhov chaw tawm,npauj npaim valve lug homkuj yog ib qho kev xaiv zoo.

 

Cov Lus Qhia Tshwj Xeeb: Kev ntsuas siab thiab kev teeb tsa

Thaum lub sij hawm yuav khoom thiab xaiv, engineers feem ntau ntsib specifications xws linpauj npaim valve lug hom class 150. Chav Kawm 150 qhia tias lub valve ua tau raws li ANSI cov qauv rau kev ntsuas siab, sib haum rau kev ua haujlwm siab ntawm kwv yees li 285 psi ntawm qhov kub thiab txias. Cov kev xaiv lag luam feem ntau kuj suav nrog Chav Kawm 300, Chav Kawm 600, thiab lwm yam kev ntaus nqi; qhov kev xaiv tshwj xeeb yog nyob ntawm qhov tsim siab ntawm cov kav dej.

 

Hais txog installation,lug hom npauj npaim valve boltingyog qhov nthuav dav tsim nyog mloog. Raws li cov bolts rau anpauj npaim valve lug homyog nws tus kheej fastened rau txhua flange, mloog yuav tsum tau them rau qhov tseeb bolt torque thaum lub sij hawm installation. Qee qhov kev tsim kho siab ua ke nrog cov lugs nrog lub cev los ntawm kev txhaj tshuaj molding txheej txheem. Qhov no pab tshem tawm txoj kev pheej hmoo ntawm kev puas tsuaj rau lub cev valve los ntawm ntau tshaj -tightening bolts. Ib txhij, qhov tsim qauv no yooj yim rau kev teeb tsa kev taw qhia, ua rau ntawm - chaw ua haujlwm yooj yim dua.

 

Rau cov ntawv thov uas yuav tsum tau ua haujlwm nquag, anpauj npaim valve lug hom iav ua haujlwm configuration yog ib qho kev xaiv. Siv tus neeg tsav tsheb cab iav los ua kom lub valve txo qis kev ua haujlwm, tshwj xeeb tshaj yog haum rau cov kab loj loj lossis siab - qhov sib txawv siab. Rau cov tshuab xav tau cov chaw taws teeb tswj, koj tuaj yeem teeb tsa hluav taws xob lossis pneumatic actuators. Ntau lub tuam txhab tam sim no tsim lawv cov actuator mounting pads raws li ISO 5211 tus qauv, ua kom yooj yim automation kev koom ua ke.

 

Kev xaiv cov khoom siv thiab daim ntawv thov scenarios

Cov khoom siv rau lub cevnpauj npaim valve lug homfeem ntau muaj xws li cov hlau nplaum, cam khwb cia hlau, stainless hlau, thiab lwm yam, xaiv raws li corrosiveness ntawm cov khoom xa tawm. Cov khoom siv rau lub rooj zaum thiab cov ntsaws ruaj ruaj yuav tsum sib haum nrog cov kev pabcuam; EPDM yog tsim rau cov dej thiab dilute acids / bases, thaum PTFE yog zoo dua rau cov tshuaj phem dua.

 

Hauv kev lag luam kho dej, qee cov tuam ntxhab muabnpauj npaim valve lug homua los ntawm yas. Piv txwv li, nyob rau hauv qee cov khoom los ntawm GF Piping Systems, lub lug feem siv stainless hlau inserts ua ke nrog lub cev los ntawm kev txhaj tshuaj molding, muab ob qho tib si corrosion kuj thiab txo qhov hnyav tag nrho. Qhov kev tsim no yog nrov hauv cov nroj tsuag tshuaj thiab desalination tej yaam num.

 

Thaum tsim cov kav dej thiab xav txog anpauj npaim valve lug hom, koj yuav tsum xyuas kom meej tias lub bolt lub voj voog txoj kab uas hla ntawm cov yeeb nkab flanges phim lub lug qauv ntawm lub valve. Feem coob ntawmnpauj npaim valve lug homli qub yog tsim raws li ANSI B16.5 lossis ASME B16.10 tus qauv, tso cai rau kev sib txuas ncaj qha rau cov qauv flanges.

 

Xaiv ibnpauj npaim valve lug homtxhais tau hais tias koj tab tom xaiv qhov kev daws teeb meem rau kev saib xyuas yooj yim thiab kev ua haujlwm yooj yim. Nws tus nqi pib yuav yog feem ntau me ntsis siab dua li wafer- hom valve. Txawm li cas los xij, dhau ntawm tag nrho lub neej ntawm cov cuab yeej siv, kev txuag nyiaj hauv kev saib xyuas lub sijhawm thiab kev txo qis hauv kev poob qis feem ntau nyob deb tshaj qhov sib txawv ntawm tus nqi pib.
