Turbine Soft foob pob valve
Txheej txheem cej luam
Lub pob valve hloov zuj zus los ntawm lub ntsaws valve. Nws qhov qhib thiab kaw qhov yog ib qho sphere. Lub pob yog siv los tig lub axis ntawm lub valve qia 90 degree kom ua tiav lub hom phiaj ntawm kev qhib thiab kaw. Pob li qub feem ntau yog siv rau hauv cov kav dej los txiav tawm, faib thiab hloov cov kev taw qhia ntws ntawm kev tshaj tawm. Pob li qub tsim nrog V-hom qhib kuj muaj kev tswj xyuas zoo. Lub pob valve tsis tsuas yog muaj cov qauv yooj yim tab sis kuj muaj kev sib khi zoo. Ntxiv mus, nyob rau hauv ib tug tej yam nominal loj ntau yam, nws yog me me, lub teeb nyob rau hauv qhov hnyav, noj tsawg cov khoom, muaj ib tug me me installation loj, muaj ib tug me me tsav torque, yog ib qho yooj yim rau kev khiav lag luam, thiab tau yooj yim qhib thiab kaw sai. Nws yog ib qho ntawm cov hom valve uas tau tsim sai heev hauv kaum xyoo dhau los. . Tshwj xeeb tshaj yog nyob rau hauv industrially tsim lub teb chaws xws li lub tebchaws United States, Nyiv, Lub teb chaws Yelemees, Fabkis, Ltalis, Spain, thiab lub tebchaws United Kingdom, pob li qub tau dav siv, thiab ntau yam thiab ntau npaum li cas siv txuas ntxiv mus, thiab tab tom mus rau qhov kub thiab txias, siab. kev kub siab, loj diameters, siab sealing zog, thiab siv tau ntev. Nrog nws lub neej ntev, kev tswj hwm kev ua tau zoo thiab kev ua haujlwm ntau hauv ib lub valve, nws txoj kev ntseeg siab thiab lwm yam kev ntsuas kev ua tau zoo tau mus txog qib siab, thiab nws tau hloov qee qhov rooj vag li qub, lub ntiaj teb li qub thiab throttle li qub. Nrog rau kev txhim kho thev naus laus zis ntawm cov pob li qub, lawv yuav siv dav dua nyob rau lub sijhawm luv luv, tshwj xeeb tshaj yog nyob rau hauv cov roj thiab cov kav dej, cov tshuab ua kom tawg thiab kev lag luam nuclear. Tsis tas li ntawd, pob li qub kuj tseem yuav dhau los ua ib qho ntawm cov hom valve hauv qhov loj thiab nruab nrab txoj kab uas hla, nruab nrab thiab tsis tshua muaj siab teb hauv lwm qhov kev lag luam.
Qhov zoo ntawm pob valve yog:
1) Nws muaj qhov qis kawg nkaus tsis kam (qhov tseeb tsuas yog sib npaug rau ib feem ntawm cov yeeb nkab ncig ntawm tib lub npe loj).
2) Vim tias nws yuav tsis tau daig thaum lub sijhawm ua haujlwm (thaum tsis muaj roj nplua nyeem), nws tuaj yeem siv tau rau hauv cov xov xwm corrosive thiab cov kua dej qis.
3) Ua kom tiav sealing tuaj yeem ua tiav nyob rau hauv lub siab loj thiab qhov kub thiab txias.
4) Kev pib sai tuaj yeem ua tiav. Lub sijhawm qhib thiab kaw ntawm qee cov qauv tsuas yog 0 nkaus xwb. Thaum lub valve qhib sai thiab kaw, kev ua haujlwm yuav tsis muaj kev cuam tshuam.
5) Lub kaw lus kheej kheej tuaj yeem muab tso rau ntawm qhov chaw ciam teb.

qhov sib txawv ntawm hlau foob thiab mos foob
Hlau Sealing Pob Valve:
Nws siv lub rooj zaum hlau, feem ntau yog cov hlau tsis muaj steel + tawv alloy, uas yuav tsum muaj kev ua haujlwm siab thiab cov txheej txheem thev naus laus zis. Nws muaj ntau yam kev siv thiab tuaj yeem siv rau hauv qhov kub thiab txias, tsis tshua muaj kub, thiab kub kub thiab kub siab ua haujlwm.
Nws tuaj yeem tiv taus qhov kub thiab txias, tiv taus hnav thiab tsim kua muag, thiab muaj cov khoom siv zoo. Qhov tsis zoo yog tias lub foob no muaj kev sib khi tsis zoo. (Feem ntau, nws raug nquahu kom siv cov hlau-pob lub pob li qub rau cov xov xwm uas muaj cov khoom siv los yog abrasive, thiab muaj qhov kub siab tshaj 250 degrees.)
Feem ntau nws yog qib V, thiab qib siab tshaj tuaj yeem yog qib VI. Mos foob li qub: feem ntau Class VI.
Soft Sealing Pob Valve:
Cov nqi pheej yig dua thiab qis dua
Lub rooj zaum valve tau muab faib ua ntau hom xws li fluorine yas, roj hmab, thiab cov resin, thiab feem ntau yog siv rau hauv qhov qub siab, qhov kub thiab txias, thiab qhov kub thiab txias.
Nws yog ib qho yooj yim kom ua tau zoo sealing nyhuv, thiab yog resistant rau corrosion, acid thiab alkali; Qhov tsis zoo yog tias nws tsis tiv taus qhov kub thiab txias, lub sealing nto yog ib qho yooj yim rau hnav, thiab cov khoom siv kho mob kuj tsis zoo. (Siv rau qhov kub thiab txias qhov xwm txheej uas yuav tsum tau sealing siab los yog nrog corrosive xov xwm thiab tsis muaj hais.)
Kev hnav tsis zoo. Tom qab siv rau ib lub sijhawm, yog tias muaj cov khoom tsis huv hauv cov kua nruab nrab, lub rooj zaum valve yuav raug hnav, ua rau muaj kev sib txuas ntxiv thiab txo qhov kev sib khi.
Muaj nuj nqi
Qhov qhib thiab kaw ib feem ntawm lub pob valve yog ib puag ncig puag ncig nrog lub qhov. Lub pob core yog siv los tig 0-90 degree rov qab thiab tawm ntawm lub axis ntawm lub valve qia kom qhib lossis kaw lub valve. Pob valve muaj ntau yam haujlwm. Lawv feem ntau yog siv rau kev hloov, txiav tawm lossis tswj kev tshaj tawm hauv cov kav dej. Ntawm lawv, peb-txoj kev pob valve tuaj yeem hloov tau yooj yim txiav tawm, faib thiab hloov cov kev taw qhia ntws ntawm qhov nruab nrab. Lub sealing nto ntawm lub pob valve feem ntau yog nyob rau hauv lub xeev kaw nrog tus kheej kheej nto, yog li nws tsis yooj yim eroded los ntawm nruab nrab. Nws yog ib qho yooj yim rau kev khiav lag luam, muaj ib tug yooj yim thiab compact qauv, thiab yuav siv tau nyob rau hauv ua hauj lwm tej yam kev mob nrog dej, natural gas, acid, solvents, thiab lwm yam.
kev saib xyuas
Muaj lub neej ua haujlwm ntev dua thiab lub sijhawm tu-dawb yuav nyob ntawm ntau yam: kev ua haujlwm ib txwm muaj, tswj qhov sib haum xeeb ntawm qhov kub thiab txias / qhov sib piv, thiab cov ntaub ntawv corrosion tsim nyog
Lus Cim: Thaum lub pob valve raug kaw, cov kua dej hauv lub cev valve tseem muaj nyob. Ua ntej kev pabcuam, tshem tawm cov kab siab thiab tawm hauv qhov chaw qhib Ua ntej kev pabcuam, tshem tawm lub zog lossis huab cua
1. Packing lock Yog hais tias lub packing culvert yog me ntsis to, lub valve qia txiv ntoo yuav tsum tau nruj nreem. Lus Cim: Tsis txhob xauv, feem ntau yog 1/4 ntiv nplhaib rau 1 lub nplhaib, qhov xau yuav nres. cov
2. Hloov lub rooj zaum thiab cov ntsaws ruaj ruaj A. Disassembly Tsev lub valve nyob rau hauv ib nrab-qhib txoj hauj lwm kom yaug tej yam khoom phom sij uas yuav nyob rau hauv thiab sab nraum lub valve. Kaw lub pob valve, tshem cov bolts thiab txiv ntseej los ntawm flanges ntawm ob sab, thiab tshem tawm tag nrho lub valve ntawm cov yeeb nkab. Disassemble lub tsav tsheb nyob rau hauv ib ntus - actuator, txuas bracket, anti-loosening washer, qia txiv ntoo, npauj npaim shrapnel, hnav-resistant ntawv, thiab valve qia packing. Tshem tawm lub cev lub kaus mom txuas bolts thiab txiv ntseej, cais lub pob valve los ntawm lub cev lub cev, thiab tshem tawm lub valve bonnet gasket. Xyuas kom tseeb tias lub pob valve nyob rau hauv "tawm" txoj hauj lwm, uas yuav ua rau nws yooj yim dua tshem tawm ntawm lub valve lub cev, thiab ces tshem tawm lub rooj zaum valve. Maj mam thawb lub valve qia downward los ntawm nruab nrab qhov ntawm lub valve lub cev kom txog thaum nws tag nrho tshem tawm, thiab ces tshem tawm O-ring thiab packing nplhaib.
CEEB TOOM: Siv ceev faj kom tsis txhob khawb lub qia nto thiab lub pob valve lub foob.
