Ib qho nyuaj- foob npauj npaim valve yog npauj npaim valve qhov twg ob sab ntawm lub sealing nto yog ua los ntawm cov hlau los yog lwm yam ntaub ntawv nyuaj. Nws txoj hauv kev ua haujlwm yog tias tig lub valve qia tsav lub phaj npauj npaim kom tig, yog li qhib thiab kaw lub valve. Thaum lub sij hawm kev sib hloov, lub phaj npauj npaim tsav lub rooj zaum valve kom tig ib yam nkaus, tsim kom muaj kev sib khi ntawm tus npauj npaim phaj thiab lub rooj zaum valve. Thaum lub phaj npauj npaim tig mus rau 90 degree, lub valve qhib tag nrho, thaum lub sijhawm ntawd tsuas yog tiv thaiv cov kua dej yog lub thickness ntawm npauj npaim phaj, uas ua rau tsis tshua muaj dej tsis kam.

Hard kaw npauj npaim valve Cov yam ntxwv nta
Cov yam ntxwv ntawm qhov nyuaj- foob npauj npaim valve suav nrog:
Kev tsim qauv tsim, compact qauv, me me, lub teeb yuag, thiab yooj yim installation thiab ua haujlwm.
Lub sealing nto yog ua los ntawm cov khoom siv hlau, precision machined thiab hauv av kom ntseeg tau tias muaj qhov tsis tshua muaj pa tawm txawm tias nyob rau hauv qhov sib txawv siab.
Qhov kev tsim qauv zoo nkauj ua rau lub valve muaj qhov tsis siv neeg sealing muaj nuj nqi uas nruj thaum nws kaw, nrog rau cov khoom siv sib khi ua kom tiav xoom xoom.
Qhov tshwj xeeb peb -txoj kev eccentric tsim tshem tawm kev sib txhuam ntawm qhov chaw sib khi, txuas lub valve lub neej kev pab cuam.
Kev tshuaj xyuas ntawm cov yam ntxwv tseem ceeb thiab qhov zoo / qhov tsis zoo ntawm Hard-Seal Butterfly Valves
1. Cov ntsiab lus zoo
(1) Zoo hnav tsis kam
Cov khub sealing yog ua los ntawm cov khoom siv tawv, uas tuaj yeem tiv thaiv kev yaig ntawm cov xov xwm uas muaj cov khoom siv, fibers, lossis cov teeb meem raug tshem tawm. Nws yog qhov tsim nyog rau kev ua haujlwm zoo heev xws li slurry, tshauv, thiab av nkos. Piv txwv li, nyob rau hauv lub desulfurization system ntawm ib tug fais fab nroj tsuag, thaum conveying slurry uas muaj gypsum hais, cov kev pab cuam lub neej ntawm ib tug nyuaj- foob npauj npaim valve yuav ua tau 3 mus rau 5 npaug ntawm ib tug mos- foob npauj npaim valve.
(2) Kev kub siab thiab kub siab ua haujlwm
Qhov kub thiab txias: Feem ntau tuaj yeem tiv taus -20℃txog 450℃(nyob ntawm cov khoom siv, xws li ceramic seals uas tuaj yeem tiv taus qhov kub siab dua), deb tshaj qhov kub siab tshaj ntawm cov mos mos npauj npaim li qub (feem ntau tsawg dua lossis sib npaug li 200 degree);
Kev ntsuas siab: tuaj yeem ua tau raws li qhov xav tau ntawm PN16 ~ PN100 (lossis siab dua), haum rau cov xwm txheej xws li cov kav dej thiab cov kav dej.
(3) Txhim khu kev sealing thiab kev pab lub neej ntev
Cov hlau sealing nto tsis yooj yim rau cov laus los yog deformed vim muaj kev hloov nyob rau hauv nruab nrab kub los yog ntev - siv sij hawm. Tshwj xeeb tshaj yog nyob rau hauv kev kub siab, nws muaj peev xwm ua tau "tus kheej- sealing" los ntawm nruab nrab siab, ua rau tsis tshua muaj to (feem ntau ua tau raws li API 598 tus qauv VI sealing yuav tsum).
(4) Ntau hom kev tshaj tawm siv tau
Nws tuaj yeem siv rau dej, chav dej, roj, acidic thiab alkaline xov xwm, thiab cov kua dej uas muaj cov khoom. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive, lub durability tuaj yeem txhim kho tau zoo los ntawm kev xaiv corrosion-cov alloys resistant (xws li 316L thiab Hastelloy).
2. Cov kev txwv
(1) Cov nqi ua haujlwm siab
Kev txiav thiab sib tsoo ntawm cov ntaub ntawv nyuaj yog qhov nyuaj, yuav tsum tau siv cov cuab yeej tshwj xeeb thiab cov cuab yeej precision (xws li tsib -axis machining center), ua rau cov nqi tsim khoom ntau dua li cov mos mos- foob npauj npaim li qub.
(2) Loj qhib thiab kaw torque
Kev sib txhuam coefficient ntawm cov hlau sealing qhov chaw yog siab, tshwj xeeb tshaj yog nyob rau hauv siab -xwm txheej, yuav tsum muaj ib tug muaj zog actuator, nce qhov chaw installation thiab nqi.
(3) Tsawg tsawg -Tsuas Sealing Performance
Qee cov ntaub ntawv hlau tuaj yeem ua rau qhov kub thiab txias (xws li cov hlau tsis zoo ib yam hauv qab no -100 degree), yuav tsum tau xaiv cov hlau tsis tshua muaj kub (xws li LCB, LC3) lossis cov qauv sib khi tshwj xeeb.
(4) Kev hloov kho tsis raug
Txoj kev sib raug zoo ntawm tus npauj npaim valve qhov kev sib hloov lub kaum sab xis thiab qhov dej ntws tsis zoo li lub pob li qub los yog tswj cov li qub; Yog li ntawd, kev xaiv ceev faj yog tsim nyog nyob rau hauv qhov tseeb flow control scenarios.
Hard kaw npauj npaim valve Kev ua tau zoo yam ntxwv
Kub Kub Resistance: Vim yog hlau sealing nto, lub zog - foob npauj npaim valve muaj siab siab -kub tsis kam, tuav ruaj khov sealing nyhuv nyob rau hauv siab - qhov kub thiab txias ib puag ncig.
Hnav Resistance: Kev hnav zoo heev ntawm cov khoom siv hlau sealing txuas ntxiv lub neej kev pab cuam ntawm lub zog - foob npauj npaim valve, txo qhov zaus ntawm kev hloov thiab kev saib xyuas.
Zoo Mechanical Properties: Lub zog - foob npauj npaim valve muaj lub zog txhua yam thiab rigidity, muaj peev xwm tiv taus qhov siab loj thiab lub zog.
