Thaum xaiv cov li qub, ib tus lej ntawm cov xwm txheej yuav tsum tau txiav txim siab, suav nrog kev siv, hom, kev siv cov qauv, tom qab muag khoom, thiab lwm yam ..
1.Determine cov kev npaj siv thiab cov xwm txheej ntawm kev siv ntawm lub valve.
Hom Media
Txiav txim siab thauj khoom nruab nrab (dej, chav dej, roj, ua kua, roj, thiab lwm yam). Piv txwv li:
Rau cov xov xwm muaj cov lus: nws yog qhov zoo tshaj plaws los xaiv cov hniav slab game lub rooj vag kom tsis txhob hnav thiab rhuav cov chaw sealing.
Rau cov xov xwm corrosive: Xaiv cov hlau tsis muaj, roj hmab - txoj kab kev lossis fluorine {}}} txoj hlua khi).
Kev kub siab: Xaiv npoo rooj zaum valve (piv txwv Z41H-40 rau Chav / Roj kub tsawg dua los yog sib npaug ntawm 425℃pob) lossis kub ua pob.
Rau cryogenic media: xaiv ib qho kev ua tiav cantogenic rooj vag valve lossis cryosphere Valve nrog lub hau npog (muaj feem xyuam thaum muaj kev sib luag ntawm -100 degree).
Siab thiab kub
Valve Rated Siab (piv txwv li PN1.6 MPa, PDA, PDA, PDA) yog xaiv raws li lub siab ntawm cov raj xa hluav taws xob siab. Kev mob siab rau qhov kub yuav tsum muaj cov khoom kub siab (xws li chromium {}} molybdenum steel valve lub cev) thiab cov khoom siv kub tsis kam (xws li LCB Cast Steel).
Daim Ntawv Thov Kev Pab Cuam
Nquag qhib thiab kaw: Xaiv lub ntiaj teb Valve lossis pob valve (hnav {{free {tiv taus zoo nkauj).
Large calibre pipe: Butterfly (DN>600mm, luv qauv tsim, qhib nrawm thiab kaw).
Cov kev cai meej: cov li qub los yog kev tswj hwm (xws li rab koob li cov rab koob rau kev tswj cov khoom siv).
ii. Xaiv ntawm valve hom thiab qauv
Kaw - tawm li qub
Rooj vag li qub: Qhib tag nrho thiab kaw nrog cov kua dej tsis yeem tabsis qeeb qhib thiab kaw (piv txwv li cov npoo ntsug rau dej, chav thiab roj).
Kev sib cuam tshuam li qub: kev tswj hwm zoo heev tab sis kev ua kua dej tsis taus (piv txwv li} 16 ncaj los ntawm kev txiav cov khoom txiav<200mm).
Pob Valve: Qhib nrawm thiab kaw, xws li sib khi zoo nkauj (xws li valve Q41F, haum rau tsawg kub, muaj siab, siab-viscosity stor). Npauj Npaim: Lub teeb yuag, qhib nrawm thiab kaw (piv txwv li cov npauj npaim nruab nrab D71X, rau dej ntshiab thiab dej hiav txwv).
Kev tswj cov qub
Throtle li qub: Kho cov Flating Flow channel Hla Hla {}}}} 16 throttle valve rau high-siab media).
Siab nyem lub valve: txiav kom txo cov raj xa dej siab (piv txwv li y43h-16 stay koob tso rau valve).
Kos Valve
LAUW DECK: Kab rov tav teeb tsa nkaus xwb (piv txwv li H41H-16, rau cov kav dej nrog cov kav dej tsis yog lossis sib npaug rau 40mm).
Xyuas li cas: tuaj yeem muab ntsia tav toj tav toj lossis ntsug H44H-25 rau DN 50-400mm PIPING).
Kev Ruaj Ntseg Valve
Caij nplooj ntoos hlav muaj kev nyab xeeb li qub: Tsis siv neeg tawm ntawm kev tsis sib haum (piv txwv li A48Y-16C, rau Chav Boilers).
III. Txheeb xyuas cov ntaub ntawv thiab sib khi ua tau zoo
Lub Cev Khoom
Cam khwb cia hlau: tsawg {{- voltage li qub (xws li grey cam khwb cia hlau HTTWAYS HLAU HTTWAYE NROG LOSSIS TSHAJ RAU 16MPA). Carbon Steel: Nruab Nrab-}} {}} siab} Cov tuab wcb ntsug rau cov ntsuas kub ntawm -29℃cc thiab 425 degree).
Stainless hlau: Corrosive kev khiav hauj lwm (piv txwv li. 304}}}}}} / 316 stainless hlau, rau khoom noj khoom haus thiab tshuaj).
Alloy Steel: kub thiab kev khiav haujlwm kub (piv txwv li cov haujlwm hauv WC9 chrome- molybdenum hlau, rau Chav pipelines tsawg dua lossis sib npaug rau 540 degree).
Muab cov khoom siv kaw
Mos foob: roj hmab thiab PTFE (polytetrafluoroethylene); Zoo tshaj plaws seuting tab sis kub tiv taus kub (piv txwv li cov roj hmab - Txoj Kab Npauj Npaim Valve D371X-10).
Fais Fab: Hlau Overlay thiab Ceramics; Kev kub siab thiab kub tsis kam, tab sis me ntsis tsis zoo khi (piv txwv li q41h-16c nyuaj lub pob valve).
Kev kuaj sealing: Cov khoom xa tuaj yuav muab daim ntawv qhia xeem xeem sib khi (piv txwv li. 1.5}} sij hawm cov haujlwm siab ua haujlwm tom qab ntsuas lub siab zoo li qub).
