8 ″ Npauj Npaim Valve: Ua tiav Cov Lus Qhia rau Cov Lus Qhia Tshwj Xeeb thiab Cov Nqi Them Nqi

Nyob rau hauv industrial pipeline engineering, lub8-nti npauj npaim valveyog ib qho khoom siv uas nquag siv. Txawm li cas los xij, ntau tus kws tshaj lij kev muag khoom tsuas yog tsom mus rau txoj kab uas hla thiab tus nqi, saib xyuas cov ntsiab lus kev paub. Qhov no feem ntau ua rau cov li qub uas tsis sib haum rau kev ua haujlwm lossis ua tsis tau sai tom qab kev teeb tsa. Raws li xyoo dhau los ntawm kev lag luam kev lag luam thiab kev xa cov qauv kev lag luam los ntawm ASMEPhau ntawv Journal of Pressure Vessel Technology, tsab xov xwm no muab kev tshuaj xyuas dav dav ntawm cov kev qhia tshwj xeeb thiab cov nqi them nqi rau 8-nti npauj npaim li qub, pab cov neeg nyeem paub ntau ntxiv txog kev txiav txim siab xaiv.

 

I. Cov Ntsiab Lus Qhia Tshwj Xeeb: Kev txiav txim siab ua haujlwm kom haum

Cov kev qhia tshwj xeeb yog qhov tseem ceeb rau seb lub valve tuaj yeem hloov kho rau koj cov kav dej. Cov kev ntsuas hauv qab no yuav tsum tau ua tib zoo txheeb xyuas.

 

1. Txoj kab uas hla thiab kev ntsuas siab

Nominal Dia: 8 nti sib haum rau DN200, ib qho tseem ceeb sib piv parameter.

Kev ntsuas siab: Cov kev ntsuas feem ntau suav nrog Chav Kawm 150, Chav Kawm 300, thiab Chav Kawm 1500 rau cov xwm txheej hnyav. Valve lub cev phab ntsa thickness thiab siab- bearing muaj peev xwm sib txawv los ntawm kev ntsuam xyuas.

Chav Kawm 150: Ua haujlwm siab tshaj plaws kwv yees li . 3.44 bar. Haum rau cov dej hauv nroog / dej ntws, qhov kub thiab txias, thiab cov xwm txheej siab.

Chav Kawm 1500: Ua haujlwm siab tshaj plaws txog li 250 bar. Siv nyob rau hauv siab - siab heev ib puag ncig xws li petrochemical thiab thermal fais fab kev lag luam.

 

2. Hom kev sib txuas (8 Nti Npauj Npaim Valve Flange yog feem ntau)

Hom kev sib txuas cuam tshuam rau installation, disassembly, thiab qhov chaw layout. Muaj peb yam tseem ceeb:

• Flanged txuas (Lug Hom / Ob Flanged): Ua raws li ASME B16.5 tus qauv. Yooj yim rau disassemble, yooj yim rau kev txij nkawm, haum rau cov kav dej uas xav tau kev tshuaj xyuas tas li.
• Hom Wafer: Chaw-txuag, haum rau cov chaw uas muaj qhov txwv kev teeb tsa.
• ⚠️ Lus ceeb toom tseem ceeb: Thaum yuav khoom, nco ntsoov xyuas qhov ntsuas qhov siab thiab qhov sib txuas ntawm qhov ntev (bolt qhov sib nrug, tig hom) ntawm flange kom tsis txhob muaj qhov tsis sib xws thiab kev teeb tsa tsis tiav.

 

3. Kev xaiv cov khoom siv (Tshwj xeeb cuam tshuam rau lub neej thiab kev tiv thaiv corrosion)

Cov ntaub ntawv sib txawv haum cov xov xwm sib txawv, nrog qhov sib txawv tseem ceeb ntawm tus nqi thiab kev pabcuam lub neej:

Cheebtsam	Cov khoom xaiv	Daim ntawv thov Scenario
Lub cev	Cast Iron	Tus nqi -zoo, haum rau cov dej dav dav (qhov kub thiab txias).
	Aluminium Alloy	Lub teeb, feem ntau yog siv rau qis - siab gases.
	Stainless hlau (CF8 / CF8M, thiab lwm yam)	Muaj zog corrosion kuj, haum rau corrosive media xws li tshuaj, kev kho dej hiav txwv.
	Hastelloy	Cov kev mob hnyav heev nrog corrosion muaj zog, siab kub, thiab siab siab; tus nqi siab heev.
Rooj Seal	Nitrile Roj Hmab (NBR)	Qhov kub thiab txias / siab, zoo roj kuj.
	Fluorocarbon Roj Hmab (FKM)	Siab -kub tsis kam mus txog 204 degree, haum rau siab - kub xov xwm.
	Ethylene Propylene Diene Monomer (EPDM)	Tsawg-kub tsis kam mus rau -45 degree, haum rau qhov chaw txias thiab dej kub.

 

4. 8 Ntiv Npauj Npaim Valve nrog Actuator

Feem ntau siv nyob rau hauv automated pipelines rau tej thaj chaw deb tswj. Actuator hom thiab cov yam ntxwv:

• Pneumatic Actuator: Muaj nyob rau hauv ib qho - ua yeeb yam (lub caij nplooj ntoo hlav rov qab) thiab ob - ua yeeb yam. Piv txwv li, Betts Industries '8-nti npauj npaim li qub muaj cov pneumatic actuators hauv cov qauv xws li cua qhib / kaw thiab lub caij nplooj ntoos hlav qhib / cua kaw, nrog siab tshaj plaws ua haujlwm siab txog 10 bar.
• Hydraulic Actuator: Muaj peev xwm tiv taus siab txog li 207 bar, haum rau hnyav - lub luag haujlwm.
• Hluav taws xob Actuator: Muaj kev tswj xyuas siab, tsim nyog rau cov ntawv thov uas xav tau kev hloov kho meej lossis qhov chaw ua haujlwm nyuaj.

Lus Cim: Npauj Npaim li qub nrog cov actuators yog technically complex thiab ho kim tshaj li phau ntawv versions, tab sis lawv zoo heev txhim kho qhov system automation.

 

II. Cov yam ntxwv cuam tshuam rau tus nqi (Vim li cas tus nqi sib txawv ntawm txhiab mus rau kaum txhiab?)

Nqe variations rau tib 8-nti npauj npaim valve yog qhov tseem ceeb, feem ntau cuam tshuam los ntawm plaub yam hauv qab no.

• 1. Cov nqi khoom siv

Txheem cam khwb cia hlau / carbon steel lub cev muaj tus nqi qis tshaj.

Stainless hlau: 3 mus rau 5 npaug kim dua li cov qauv cam khwb cia hlau.

Hastelloy / Precipitation Hardening Stainless Hlau: Vim muaj kev ua haujlwm siab heev thiab cov nqi ntawm cov khoom siv, cov nqi tuaj yeem dhau 10 npaug ntawm cov khoom siv. Qhov no yog qhov tseeb tshwj xeeb tshaj yog thaum cov khoom tseem ceeb xws li qia siv cov qib stainless hlau tshwj xeeb.

• 2. Actuator Configuration

Phau ntawv hom: Tus nqi qis tshaj.

Pneumatic Actuator Hom: 30% mus rau 80% kim tshaj li phau ntawv hom.

Fais Actuator Hom: 50% mus rau 150% kim tshaj li phau ntawv hom.

Hom txawv: Imported actuators (piv txwv li, Fisher, Metso) yog 2 mus rau 10 npaug kim dua li cov actuators hauv tsev.

Ntse nta: Intelligent actuators nrog cov yam ntxwv zoo li cov neeg kho tshuab qhov chaw lossis qhov kev twv ua yuam kev yog 80% txog 200% kim dua li hom pib / tawm.

• 3. Daim ntawv pov thawj thiab cov qauv ua raws

Cov ntawv pov thawj yooj yim: API 6D thiab CE daim ntawv pov thawj yog cov kev cai nkag hauv kev lag luam kev sib tw. Valves nrog cov ntawv pov thawj no yog 20% ​​mus rau 50% kim dua li cov qauv qauv.

Kev mob siab heev Customization: Cov ntawv thov xws li lub zog hluav taws xob nuclear lossis sib sib zog nqus- cov roj hiav txwv thiab roj yuav tsum tau kuaj tshwj xeeb thiab cov ntawv pov thawj qib kev nyab xeeb nuclear. Cov nqi rau cov li qub yog 3 mus rau 10 npaug siab dua li cov qauv qauv.

• 4. Customization thiab Order Quantity

Kev yuav khoom ntau: Tau txais 10% mus rau 30% txo nqi.

Ib Cheeb Tsam Tsis yog -txheej txheem Customization: Vim 分摊 ntawm kev tsim, cuab yeej, thiab cov nqi kuaj, tus nqi them feem ntau yog 30% txog 100%.

 

III. Cov lus qhia txog kev yuav khoom: txhais cov xwm txheej ua haujlwm ua ntej, tom qab ntawd sib piv cov nqi

Tsis txhob saib tus nqi xwb! Nws raug nquahu kom ua raws li cov kauj ruam no rau kev xaiv:

Txhais hom nruab nrab(dej, roj, corrosive kua?), ua hauj lwm kub, thiab siab ntau yam.

Raws li cov qauv txheej txheem(xws li ASME cov ntawv xov xwm), xaiv qhov kev ntsuas siab sib xws (Class 150/300/1500, thiab lwm yam) thiab hom kev sib txuas.

Txheeb xyuas lub cev thiab cov khoom siv zaumlos xyuas kom meej corrosion kuj thiab kub kam rau ua.

Puas xav tau automation?Xaiv hom actuator thiab cov haujlwm uas yuav tsum tau ua (pneumatic / hluav taws xob, xav tau qhov chaw ntse?).

Tshawb xyuas cov ntawv pov thawj xav tau(API 6D, CE, thiab lwm yam).

Sib piv cov nqe lus raws li cov xwm txheej saum toj no, muab qhov tseem ceeb ntawm cov khoom raws li cov khoom siv txhim khu kev qha. Txawm hais tias kev nqis peev thawj zaug tuaj yeem siab dua me ntsis, nws txo qis cov nqi tu yav tom ntej thiab txuas ntxiv lub neej kev pab cuam.

 

Cov ntsiab lus

Cov kev qhia tshwj xeeb ntawm 8-inch npauj npaim valve ncaj qha txiav txim siab nws qhov haum rau kev ua haujlwm thiab nws lub sijhawm ntev- kev ntseeg siab. Tus nqi yog cuam tshuam los ntawm cov ntaub ntawv, actuator configuration, ntawv pov thawj, thiab customization xav tau. Cov lus qhia no yog tsom los pab koj kom tsis txhob muaj teeb meem tshwm sim thaum lub sijhawm yuav khoom thiab xaiv lub valve zoo tshaj plaws rau koj qhov project.
