Valve e fa'avasegaina e ala i le lapopoa / mamafa / vevela / mea / feso'ota'iga / taulimaina

Valves e faʻavasegaina i le tele o le tele / mamafa / vevela / meafaitino / fesoʻotaʻiga / taulimaina O le faʻaleagaina o vailaʻau o le uamea e faʻalagolago i le vevela, avega faʻainisinia o vaega feteʻenaʻi, le mautu o sulfides o loʻo i totonu o mea lubricating ma lo latou faʻafefeteina acid, umi o le faʻafesoʻotaʻi ma le auala ma le aafiaga catalytic o uamea i luga o le faagasologa nitriding, o le fua faatatau o le liua o molelaula o corroding mea i metals, ma isi. Talu ai ona o le pala e tupu i fegalegaleaiga faʻafuaseʻi i le va o uʻamea ma le siʻosiʻomaga o loʻo siomia ai, o le faʻafefea ona faʻaesea metala mai le siʻosiʻomaga lata ane poʻo le faʻaaogaina o mea faʻapipiʻi e le o ni metallic ua avea ma popolega masani. 2. Ua lauiloa o le faaleagaina o le uamea ua i ai se aafiaga tele i le ola, faatuatuaina ma le ola tautua o valve. O le gaioiga a mea faʻainisinia ma faʻamaʻi i luga o le uʻamea e matua faʻateleina ai le aofaʻi o le ofuina i luga o le faʻafesoʻotaʻi. Valve i le taimi o le faʻagaioiga, feteʻenaʻiga o luga o le aofaʻi atoa o laei. I le taimi o le faʻaogaina o le valve, e masaesae ma faʻaleagaina mea faʻafefe ona o le gaioiga faʻainisinia faʻatasi ma le vailaʻau poʻo le eletise eletise i le va o uʻamea ma le siosiomaga. Mo le valve, o lona pipeline galue tulaga tau tau e faigata; O le i ai o le hydrogen sulfide, carbon dioxide ma nisi o meaola faʻalaʻau i totonu o le suauʻu, kesi masani ma vai faʻatanoa e faʻapupulaina ai le malosi faʻaleagaina o le uʻamea, ma vave ai ona leiloa lona malosi e galue ai. 3, ona o le pala kemikolo o le uamea e faalagolago i luga o le vevela, uta masini o vaega feteʻenaʻiga, mea lubricating o loʻo i ai le sulfide ma lona malosi faʻamautu faʻamautu ma feololo le umi o fesoʻotaʻiga ma uʻamea i luga o le nitriding faagasologa o catalytic gaioiga, pala o molelaʻau o mea. i luga o le saoasaoa o le liua uamea ma isi. O le mea lea, o le anticorrosion metotia o le valve uʻamea (poʻo le fua) ma le faʻaogaina o le valve mea faʻapipiʻi ua avea ma se tasi o autu o suʻesuʻega alamanuia valve. 4, uamea valve anticorrosion, e mafai ona malamalama o le valve uamea ua ufiufi e puipuia ai le tulaga o le puipuiga mai le pala (e pei o vali, vali, mea lubricating, ma isi), ina ia mafai ai e le valve pe i le gaosiga, faasaoina, felauaiga. pe i le faagasologa atoa o lona faaaogaina e le pala. 5, auala uʻamea anticorrosion uamea e faalagolago i le vaitaimi o le puipuiga manaomia, felauaiga ma tulaga faasao, valve fausaga uiga ma mea, ioe, e mafaufau i le aafiaga tau tamaoaiga o le aveesea anticorrosion. Fa'avasegaina o valve e tusa ai ma le fa'aigoa o le lautele / mamafa / vevela / mea / feso'ota'iga faiga / faiga fa'agaioiga Fa'avasegaina o va'a e tusa ai ma le fa'aigoa igoa 1, "vave la'ititi la'ititi" DN≤40mm 2, "valve vaeluagalemu" fa'avasega DN50-300mm 3, "valve lautele lautele" Nominal diameter DN350-1200mm valve 4, "valve diameter tele" nominal diameter DN≥1400mm valve Valves ua fa'avasegaina e pei ole lapopo'a numera 1, "valve caliber la'ititi" nominal diameter DN≤40mm valve 2, "medium valve. valve caliber "valau ta'oto DN50-300mm valve 3, "valu fa'alava tele" va'a fa'aigoa DN350-1200mm valve 4, "valve diameter tele" valve fa'aigoaina DN≥1400mm valve Fa'avasegaina o valve fa'aigoa igoa 1, "vacuum valve" e maualalo le mamafa o galuega. nai lo tulaga masani alavai o le ea 2, "vaivai maualalo o le mamafa" nominal pressure PN≤ 1.6mpa valve 3, "valve omiga masani" nominal pressure PN2.5-6.4mpa valve 4, "veve pressure valve" nominal pressure PN10.0-80.0mpa valve 5, "vave maualuga maualuga" fa'aigoa fa'aigoa PN≥100MPA valve E tusa ai ma le fa'avasegaina o le va'a vevela vevela fa'avasegaina 1, "vave vevela maualuga" T> 450℃ valve 2, "valve vevela vevela" 120℃≤ T ≤450℃ valve 3, "valve vevela masani" -40℃≤ T ≤120℃ valve 4, "valve maualalo vevela" -100℃≤ T ≤-40℃ valve 5, "** valve vevela" T
