Yuav ua li cas xaiv Txoj Cai Txoj Cai Stainless Hlau Rooj Zaum Valve Qauv?

Cov rooj vag stalves, raws li ib tug tseem ceeb tswj lub ntsiab hauv kev siv hluav taws xob, yog siv dav hauv petrochemical, hluav taws xob muaj zog, tshuaj, khoom noj khoom haus thiab dej haus. Nws cov tub ntxhais muaj nuj nqi yog txiav tawm thiab ntws tawm hauv kev txav ntawm discs los xyuas kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm lub system. Txawm li cas los xij, yog tias qhov kev xaiv tsis yog, tej zaum yuav ua rau muaj kev cuam tshuam nrog kev cuam tshuam, lossis txawm tias muaj kev phom sij thiab kev nyab xeeb kev nyab xeeb. Yog li ntawd, cov txheej txheem xaiv ntawm kev tshawb fawb systematic yog qhov tseem ceeb. Daim ntawv no yuav muab cov lus qhia ua tiav rau kev xaiv cov rooj vag stainless hlau los ntawm peb qhov ntev: cov tsis muaj zog, ua haujlwm txheem.

Cov yam ntxwv xov xwm
1.Corrosion
Cov acidity / alkalinity thiab chloride ion concentration lub nruab nrab ncaj qha rau cov khoom xaiv:

• 304 Stainless hlau: Haum rau tsis muaj zog corrosive media (piv txwv li dej, chav dej, huab cua, thiab lwm yam), tus nqi qis.
• 316/53/36L Stainless Hlau: Muaj cov molybdenum, yog resistant rau cov muaj zog acids thiab alkalines acid, hydrocoric acid,} Alkali Kev lag luam, thiab lwm yam.
• PTFE - Kab rooj vag latures: Stainless hlau lub cev muaj, haum rau kev sib txuas cov roj acid, alkalis.

2.Temperatature thiab siab:

• Kev kub siab chav dej: Cov neeg muag khoom siv tau. Lub billows insulate nruab nrab ntawm lub valve los ntawm lub valve qia thiab tiv thaiv kom tiv thaiv kom muaj qhov kub loj nthuav dav. Piv txwv li, hluav taws xob rooj zaum rooj vag ntaiv (xws li Z46Y-320p) yog siv rau cov roj hluav taws xob hauv thermal nroj tsuag thiab muaj peev xwm kub hnyiab tau txog li 600℃thiab 32 MPa.
• High -} pa valve puag ncig lossis kev kub siab lub kaum rooj vag li qub tuaj yeem tiv thaiv kev kub siab. Piv txwv li, PS160 / 320 siab {{4} Kev kub lub kaum rooj vag li qub yog siv rau hauv tshav kub hloov cov roj ntau yam tshuaj lom neeg. Lub cev lub cev yog tsim los ntawm tag nrho Forging txheej txheem thiab muaj lub zog siab dua.

3.Uscosity thiab muaj kev mus ncig

High - Viscosity me li bitumen thiab resin yuav tsum muaj cov kab loj loj los txo cov ntws tsis kam. Piv txwv li, li qub nrog txoj kab uas hla nrog DN200 lossis loj tuaj yeem txo qhov ntev ntawm lub sijhawm ntawm cov khoom nruab nrab hauv lub cev nruab nrab thiab tiv thaiv thaiv.
4.TOXICITY / FLAMFABITY

• Yuav tsum tau xaiv cov xov xwm toxic: ib qho rov qab {{0} - Txheem Valve Quav

• Kev ua haujlwm sib koom ua haujlwm: Cov rooj vag uas yog tsim nyog rau tsis yog -}} yuav tsum muaj, tus nqi yuav qis dua.

Pipeline System tsis
1.Diameter txuam

Valve diameters yuav tsum cov pipeline DN tus nqi (piv txwv li DN: kom tsis txhob muaj kev cuam tshuam nrog kev teeb meem vim li cas nrog txoj kab uas hla.

Nplooj ntawv 2.Cov txheej txheem

• Threaded kev sib txuas (NPP): Haum rau me me caliber muaj voltage pipelines muaj log qis (piv txwv li, yooj yim rau nruab tab sis kev ua haujlwm tsis zoo tab sis kev sib khi tsis zoo.
• Flanged kev twb kev txuas (Pn10-PN40): Haum rau kev kub siab txoj kab uas hla (xws li siab dua), ruaj ntseg kaw los ntawm ntsia ntsia zawm.

Kev ua tau zoo thiab cov qauv zoo
1.Sealed qib
