10 ″|10 nti npauj npaim valve ntsia liaj qhov rooj loj thiab qhov hnyav ntawm qhov zais cia uas txiav txim siab koj qhov project ua tiav

Ib tus neeg siv khoom ib zaug tau hais rau peb tias lawv 10 "tus npauj npaim valve tsis tuaj yeem nruab rau ntawm qhov chaw tsim kho. Lub qhov ntsia liaj qhov rooj tsis sib haum nrog lub qhov flange, cov neeg ua haujlwm tau tos ntawm -site, thiab tus thawj tswj hwm qhov project tau chim heev. Tom qab ntawd peb pom tias lawv tsuas yog mob siab txog tus nqi thaum yuav khoom thiab tsis tau txheeb xyuas qhov loj ntawm lub ntsia liaj qhov rooj. Qhov teeb meem zoo li no yog ib yam nkaus hauv cov kav dej - xaiv qhov tsis ncaj ncees lawm valve ob npaug rau cov nqi installation thiab ncua sij hawm.

 

Koj puas xav tias yuav ib10 ″ npauj npaim valvetsuas yog xaiv qhov loj nominal? Lub qhov ntsia hlau tsis zoo, qhov hnyav tshaj qhov kev txhawb nqa load, lossis pom tias koj tsis tuaj yeem txuas tus actuator tom qab ntawm - ib qho yuam kev zoo li qhov no ntau tshaj qhov txaus.

 

Cov ntsiab lus

 

Peb rhuav tshem plaub qhov tseem ceeb tshaj plaws rau 10 nti npauj npaim valve: bolt loj, qhov hnyav, tus nqi tiag tiag, thiab cov kev cai sib txuam rau kev hloov kho automation (nrog actuator). Koj yuav nkag siab tias yog vim li cas li qub ntawm tib lub npe loj tuaj yeem sib txawv hauv qhov hnyav los ntawm ob npaug, thiab vim li cas qee qhov "pheej yig deals" yuav raug nqi ntau dua.

 

1. Tsis yog 10 nti npauj npaim valve bolt loj ua rau kev teeb tsa npau suav phem

Ntau tus neeg xav tias tag nrho 10-nti npauj npaim li qub muaj qhov zoo tib yam ntsia liaj qhov rooj. Hauv kev muaj tiag, 10 nti npauj npaim valve bolt loj nyob ntawm seb nws yog hom wafer lossis hom lug, thiab qhov tseem ceeb tshaj, tus qauv flange ntawm koj cov kav dej.

 

Raws li ASME B16.5 los yog B16.47, 10-nti 150-phaus flange muaj lub voj voog txoj kab uas hla ntawm 14 1/4 ntiv tes (kwv yees . 362 hli) nrog 12 lub qhov taub. Txawm li cas los xij, yog tias koj yuav lub PN16 valve, lub voj voog txoj kab uas hla yuav nyob ib ncig ntawm 355 hli. Txawm tias ob peb millimeters tawm thiab cov bolts yuav tsis dhau.

Kuj tseem muaj cov xov sab ntawm lub lug- hom li qub - qee lub tuam txhab siv 1-inch NPT, lwm tus 1-inch BSP. Lub kaum sab xis sib txawv, yog li cov ntsaws ruaj ruaj yuav tsis ntsia hlau thaum tuag- xaus kev teeb tsa. Xyoo tas los, cov nroj tsuag tshuaj yuav tsum tau rov kais xov ntawm qhov chaw thiab muab peb lub li qub ntawm ib lub raj xa dej vim qhov teeb meem no.

 

Yog li thaum lees paub 10 nti npauj npaim valve ntsia liaj qhov rooj loj, tsis txhob tsuas yog xyuas cov naj npawb ntawm qhov - txheeb xyuas lub bolt lub voj voog txoj kab uas hla thiab xov specification ib yam nkaus. Qhov kev xyaum zoo tshaj plaws yog sib piv cov duab kos nrog rau ntawm - qhov chaw flange qhov sib nrug; Tsis txhob cia siab rau tus neeg muag khoom hais tias "nws yog universal."

 

2. 10 ntiv tes npauj npaim valve hnyav cuam tshuam ntau tshaj li tus nqi thauj khoom xwb

Valve qhov hnyav yuav zoo li tsis tseem ceeb, tab sis nws tuaj yeem ua mob taub hau loj ntawm -site. Lub 10 nti npauj npaim valve qhov hnyav sib txawv: ib qho cam khwb cia- hlau wafer liab qab yog kwv yees li . 31 kg (69 lbs), thaum tag nrho stainless hlau version tuaj yeem tshaj 45 kg. Yog hais tias koj xaiv ib tug nrog ib tug gearbox, ntxiv 10-12 kg.

Qhov hnyav txiav txim seb muaj pes tsawg tus neeg ua haujlwm xav tau rau kev nqa thiab seb qhov kev txhawb nqa xav tau kev txhawb nqa. Hauv qhov project cog dej yav dhau los, tus neeg yuav khoom siv nyiaj txiag txhawb nqa raws li cam khwb cia- hlau li qub, tab sis cov khoom xa tuaj tau cam khwb cia hlau - 30% hnyav dua. Txhawb deformed thiab xav tau rework, ntxiv ob lub lis piam rau lub sij hawm.

 

Tsis tas li ntawd, yog tias koj npaj yuav ntxiv tus actuator tom qab, koj yuav tsum suav rau tag nrho cov load ntawm lub valve ntxiv rau actuator. Qee lub valve muaj lub cev nyias; mounting lub pneumatic actuator tuaj yeem dhau lub caj dab, ua rau lub sijhawm ua haujlwm. Tias yog vim li cas ntau tus kws tshaj lij kev yuav khoom tam sim no xav kom cov tuam txhab muab cov ntaub ntawv hnyav tag nrho suav nrog cov actuator rau kev tshawb xyuas cov kav dej thaum ntxov.

 

3. Cov nqi zais tom qab 10 nti npauj npaim valve nqe

Hais txog tus nqi, 10 nti npauj npaim valve tus nqi ntawm ob peb puas mus rau ntau txhiab US las. Tab sis cov kev xaiv pheej yig dua tsis tas yuav txuag nyiaj.

 

Ib qho yooj yim PVC wafer npauj npaim valve yuav raug nqi tsuas yog $ 200, tab sis nrog lub siab ntsuas ntawm 150 psi, nws yuav tawm sai sai hauv chav ua haujlwm. High -kev ua tau zoo nickel-aluminium bronze li qub ntsib AWWA C504 tuaj yeem tiv taus ntau dua 200 psi, yog li lawv cov nqi siab dua.

 

Cov khoom foob yog lwm yam. EPDM yog tsim rau dej, thaum FKM tiv taus roj thiab kub kub. Yog hais tias koj tsis qhia, manufacturers default rau

EPDM, uas swells sai heev nyob rau hauv oily media. Tus nqi zog ntawm kev hloov cov ntsaws ruaj ruaj ib zaug tuaj yeem sib npaug ib nrab ntawm tus nqi valve.

 

Cov kws tshuaj ntsuam xyuas suav tag nrho cov nqi raws li: 10 nti npauj npaim valve nqe + installation & commissioning nqi + tu nqi tshaj tsib xyoos. Feem ntau, tus nqi qis tshaj - tus xa khoom sib tw ua rau muaj kev ua raws li ntau tshaj - teeb meem. Tias yog vim li cas ntau lub tuam txhab engineering nyiam tsim cov tuam txhab xws li COVALVE uas muaj kev txhawb nqa tag nrho lub neej - tsawg kawg koj tuaj yeem nrhiav kev txhawb nqa thaum muaj teeb meem.

 

4. Yog vim li cas ntau tej yaam num qhia10 nti npauj npaim valve nrog actuator

Cov nqi ua haujlwm nce ntxiv, thiab kev tswj chaw taws teeb tau dhau los ua tus qauv. Ntau qhov haujlwm tshiab tam sim no xav tau li qub nrog cov actuators ua ntej- ntsia - nrhiav 10 nti npauj npaim valve nrog actuator ua ib pob tiav tshem tawm ntawm - qhov chaw sib txuam teeb meem.

 

Tab sis cov actuators tsis yog bolted ntawm random. Torque yuav tsum muaj rau 10-inch npauj npaim valve feem ntau yog li ntawm 4,000 mus rau 6,000 nti-lbs, nyob ntawm seb lub siab tshaj tawm thiab qhov sib txawv. Yog tias koj yuav tus actuator cais, thawj zaug paub meej tias lub valve puas muaj ISO 5211 mounting flange thiab nws lub qhov ntsia hlau qhov sib nrug. Peb tau muaj cov neeg muas zaub yuav cov actuators tsuas yog kom pom cov mounting qhov tsis sib xws, ua rau rov qab thiab qeeb mus txog ib hlis.

 

Txoj hauv kev nyab xeeb dua yog kom cov neeg tsim khoom muab cov khoom ua ntej - sib dhos. COVALVE's 10 nti npauj npaim valve nrog cov khoom siv actuator undergo torque thiab kev sim ua haujlwm ua ntej xa khoom, nrog rau lub sijhawm hloov thiab tso zis torque ua ntej-calibrated rau ntsaws-thiab- ua si siv ntawm -site. Tshwj xeeb tshaj yog nyob rau hauv tawg-cov ntaub ntawv pov thawj, pneumatic actuators nrog lub caij nplooj ntoos hlav rov qab xyuas kom tsis txhob poob-kaw ntawm huab cua poob rau kev nyab xeeb dua.

 

5. Ob lub ntsiab lus tseem ceeb tshaj plaws thaum xaiv 10 nti npauj npaim valve

 

Thawj yog cov khoom siv zaum. Cov neeg feem ntau xav tias tag nrho cov roj hmab zoo ib yam, tab sis EPDM thiab NBR sib txawv heev hauv qhov kub thiab txias. Qhov thib ob yog kev taw qhia tus neeg teb xov tooj - tswj kev taw qhia thiab lub iav tus neeg teb xov tooj txoj hauj lwm yuav tsum tau lees paub thaum xaj, txwv tsis pub tus kov yuav tsoo phab ntsa ntawm - qhov chaw thiab yuav tsum tau disassembly thiab reinstallation.

 

Tsis tas li ntawd, yog tias koj npaj yuav hloov mus rau kev tswj tsis siv neeg tom qab, xaiv ib phau ntawv valve nrog ISO 5211 sab saum toj flange tam sim no yog li koj tuaj yeem ntxiv tus actuator yam tsis tau hloov lub cev.

 

Lub 10 nti npauj npaim valve tsis nyuaj, tab sis cov ntsiab lus me me tuaj yeem ua rau muaj teeb meem loj. Qhia kom meej qhov loj me, qhov hnyav, tus nqi qauv, thiab automation compatibility upfront, thiab koj qhov project yuav zam qhov tsis tsim nyog.
