Lub viav vias kos valve yog siv ntau yam nruab nrab xws li chav dej, dej, nitric acid, roj, khoom oxidizing media, acetic acid, thiab urea. Cov no feem ntau yog siv hauv tshuaj, roj av, chiv, tshuaj, hluav taws xob, thiab lwm yam lag luam. Txawm li cas los xij, cov li qub no tsim nyog rau kev ntxuav thiab tsis yog rau cov nruab nrab uas muaj cov impurities siab heev. Cov li qub no kuj tsis pom zoo rau cov nruab nrab uas yog pulsating. Peb yog ib tug ntawm cov sab saum toj viav vias kos valve lwm tus neeg uas tsim superior zoo li qub.
Lub di ncauj foob tam sim no ntawm lub disk ua kom nws tsis xoob.
Lub disc los yog lub kaus mom tsim ua kom yooj yim rau kev tswj xyuas
Lub disc ntawm lub valve tuaj yeem txav me ntsis ob qho tib si ntsug thiab kab rov tav kaw kom zoo.
Thaum lub disk yog lub teeb hauv qhov hnyav, nws yuav tsum muaj qhov tsawg kawg nkaus kom kaw lossis qhib lub valve.
Lub pob khawm nyob ib ncig ntawm lub ncej nrog cov pob txha muaj zog ua kom lub zog ntawm lub valve.
Lub viav vias hom kos li qub yog tsim los tiv thaiv qhov nruab nrab hauv cov yeeb nkab los ntawm ntws rov qab. Thaum lub siab dhau los ua xoom, lub valve kaw tag nrho, uas tiv thaiv qhov rov qab ntawm cov khoom hauv cov kav dej.
Turbulence thiab siab poob hauv viav vias-hom wafer kos li qub yog tsawg heev.
Cov li qub no yuav tsum tau teeb tsa kab rov tav hauv cov kav dej; Txawm li cas los xij, lawv tuaj yeem raug ntsia tau rau hauv.
Nruab nrog lub qhov hnyav thaiv, nws tuaj yeem kaw sai sai hauv cov kav dej thiab tshem tawm cov dej rauj puas tsuaj
Cov ntau yam tuaj yeem tsim kho kom haum rau koj daim ntawv thov, nrog rau kev tsim kho lub cev, cov khoom siv, thiab cov yam ntxwv ntxiv tau ua kom tau raws li koj cov kev xav tau. Raws li ISO 9001 tau ntawv pov thawj, peb txais yuav txoj hauv kev los xyuas kom meej qhov zoo, koj tuaj yeem paub tseeb ntawm kev ntseeg tau zoo thiab kev sib khi ua tau zoo los ntawm kev tsim lub neej ntawm koj lub cuab tam.

Thaum cov xov xwm raug tso tawm los ntawm lub tshuab nqus dej mus rau lub qhov tso dej tawm, qhov rov qab ntws yuav tshwm sim thaum lub twj tso kua mis nres. Check valves yog siv los tiv thaiv qhov no. Hom valve feem ntau siv rau qhov no yog ko taw valve.
Lub check valve muaj ob qhov chaw nres nkoj - qhov nkag thiab qhov hluav taws xob - thiab lub tshuab kaw / kaw. Cov yam ntxwv tshwj xeeb ntawm cov pob valve uas txawv ntawm lwm hom li qub xws li pob thiab npauj npaim li qub yog tias, tsis zoo li cov li qub no uas xav tau qee yam kev ua haujlwm los ua haujlwm, kos li qub yog tus kheej ua haujlwm. Kuaj li qub ua haujlwm tau txais, tso siab rau qhov sib txawv siab kom tswj tau qhov zoo. Nyob rau hauv lawv txoj haujlwm ua ntej, cov tshev valve raug kaw. Thaum cov xov xwm ntws los ntawm qhov chaw nres nkoj inlet, nws lub siab qhib lub kaw lus. Thaum lub siab ntws tawm hauv qab lub siab tawm vim qhov ntws raug kaw, lossis lub siab ntawm lub qhov hluav taws xob sab nraud ua ntau dua vim li cas, lub kaw lus kaw tam sim ntawd kaw lub valve.
