I. Cov Ntsiab Lus Txheej Txheem thiab Cov Ntsiab Cai Tseem Ceeb
1. Kev txhais thiab qauv
A Wafer Hom Kos Valveyog ib hom ntawm valve uas cia li qhib thiab kaw hauv teb rau qhov khiav ntawm nruab nrab. Nws lub cev yog tsim nyob rau hauv cov duab ntawm nyias wafer, uas tau yooj yim clamped nruab nrab ntawm ob flanges siv nws kom haum yam tsis tau noj qhov chaw ntxiv hauv lub raj dej.
Cov khoom tseem ceeb:
Valve disc: tuaj yeem ua rau viav vias dawb ncig ib ncig ntawm cov ncej los yog swb raws li lub axis, zoo tswj cov kev tsis txaus siab ntws ntawm nruab nrab.
Lub cev lub cev: Lub cev feem ntau ua los ntawm cov ntaub ntawv xws li cam khwb cia hlau, stainless hlau, thiab nws cov nplaim taws tuaj yeem kho kom muab cov khoom tiv thaiv corrosion.
Sealing nto: Ua los ntawm cov roj hmab, hlau, lossis cov khoom siv sib xyaw ua kom muaj kev kaw lub ntsej muag kom nruj thaum kaw.
2. Ua haujlwm ua haujlwm
Qhib Lub Xeev: Thaum nruab nrab ntws tawm hauv kev taw qhia rau pem hauv ntej, nws thawb lub pob zeb lub zog lossis lub caij nplooj ntoos hlav tsis kam, nrog rau nruab nrab kom dhau mus.
Kaw Lub Xeev: Thaum nruab nrab ceases ntws los yog pib ntws mus rau hauv kev sib txawv, lub siab ntawm lub zog nqus, lossis lub zog ntawm lub caij nplooj ntoo hlav. Qhov kev ua no txwv tsis pub backflow.
Tub ntxhais muaj nuj nqi: thawj txoj haujlwm ntawm covWafer Hom Kos Valveyog los tiv thaiv lub backflow ntawm nruab nrab hauv lub raj dej. Qhov no pab tiv thaiv cov twj, compressors, thiab lwm yam khoom siv los ntawm kev puas tsuaj thiab ua kom ua haujlwm ntawm cov txheej txheem system.
Ii. Cov Hom Main thiab Cov yam ntxwv
1. Kev cais los ntawm cov khoom siv
Khoom siv hlau:
Cam khwb cia hlau: tus nqi qis, haum rau cov tsis yog-corrosive media xws li dej thiab huab cua.
Stainless hlau: corrosion-resistant, siv hauv tshuaj, zaub mov, dej hiav txwv, thiab lwm yam xwm txheej.
Carbon Steel \/ Alloy Steel: Tiv thaiv kom muaj siab thiab kub, haum rau chav, roj, thiab roj roj pipelines.
Cov khoom siv tsis yog xim hlau:
YAS: Resistant rau cov kua qaub thiab alkalis, lub teeb yuag, thiab siv hauv cov dej kho thiab tshuaj siv tshuaj lom neeg.
Cov roj hmab-lined thiab fluorine-lined lined: lub puab txheej ntawm cov khoom siv hlau-lub cev muaj zog, ua rau nws tuav cov xov xwm corrosive.
2. Kev faib tawm los ntawm kev sib khi
Mos sealing: lub valve disc lossis lub rooj ua yog tsim los ntawm cov ntaub ntawv xws li roj hmab thiab PTFE, uas muab cov khoom sib khi zoo. Cov li qub yog qhov zoo rau cov ntawv thov tsawg-, ntawm qhov kub thiab txias, thiab siv nrog cov xov xwm corrosive.
Lub cev ntim khoom: hlau-rau-hlau foob, tiv taus cov kub thiab muaj kev kub siab, siv cov pa taws kub, thiab lwm yam haujlwm ua haujlwm.
III. Cov ntsiab lus tseem ceeb rau kev xaiv thiab kev teeb tsa
1. Cov ntsiab lus tseem ceeb rau kev xaiv
Nominal Diam thiab Siab Ntsuam Xyuas: phim cov yeeb nkab loj thiab tsim kev tsim. Rau cov scenacos siab, tuab-walled valve lub cev yuav tsum tau xaiv.
Cov yam ntxwv nruab nrab:
Cov xov xwm hauv kev tshaj tawm: Xaiv cov hlau tsis xeb, cov tshuaj fluorine-lined, lossis cov ntaub ntawv yas.
Rau cov xov xwm muaj cov lus: Xaiv viav vias lossis y-hom kuaj xyuas li qub kom tiv thaiv nqa-hom-hom valve disc los ntawm kev nyam.
Flow kev taw qhia thiab cov chaw teeb tsa: rau wafer hom, flange spacing yuav tsum tau tshwj tseg. Cov qauv luv luv yog nyiam kom txuag tau qhov chaw.
2. Txhim kho kev ceev faj
Kev taw qhia kom yog: tus xub cim ntawm lub cev lub cev yuav tsum muaj raws li cov kev coj ntws ntawm nruab nrab. Rov qab installation yuav ua rau lub valve kom swb.
Flange txuam: Siv flanges uas phim lub siab ntsuas ntawm lub valve. Bolts yuav tsum ua kom nruj tusyees kom tiv thaiv tsis pub lossis deformation ntawm lub cev valve.
Zam kev poob siab: nws raug pom zoo rau series tsis yog nyob rau hauv cov kav dej loj los txo cov dej rauj nyhuv thaum lub valve disc kaw.
Chaw saib xyuas: chaw muag khoom: Qhov chaw txaus yuav tsum tau tshwj tseg rau disassembling lub valve disc rau kev kuaj, tshwj xeeb tshaj yog rau cov qauv caij nplooj ntoo hlav lossis nqa hom.
Lub ntsiab
TusWafer Hom Kos Valve, nrog nws cov txiaj ntsig ntawm cov qauv kev cog lus, cov nqi yooj yim, thiab tus nqi qis, tau dhau los ua kev tiv thaiv lub thaub qab ntawm kev tshaj tawm hauv kev lag luam.
