bann valv gate ordiner i zeneralman refer avek bann valve gate ki'n ganny sele dir. sa lartik i analiz an detay diferans ant bann soft-sealed gate valve ek bann gate valve ordiner. si ou satisfe avek larepons, silvouple donn VTON en pous anler.
senpleman, bann valv laport ki'n ganny sele dou i bann sele ant bann metal ek non-metal, tel ki nilon\tetrafluoroethylene, e bann valv ki'n ganny sele dir i bann sele ant bann metal ek metal;
bann soft-sealed gate valve e hard-sealed gate valves i refer avek bann materyo sele pour sez valve. bann sele dir i ganny presizeman masin avek materyo sez valv pou asir presizyon avek nwayo valv (boul), zeneralman feray ek kwiv. bann sele mou i refer avek bann materyo sele ki ganny enkli dan sez valv koman bann materyo non-metalik. Akoz bann materyo soft seal i annan en serten elastisite, bann legzizans presizyon prosesis i relativman pli ba ki bann hard seal. nou fer referans avek bann karakteristik VTON pou dekrir diferans ant bann soft-sealed gate valve enporte ek bann hard-sealed gate valve enporte.
1. Materyo sele
1. bann materyo sele sa de i diferan.bann valv baro sele doui zeneralman ganny fer avek lastik oubyen polytetrafluoroethylene. bann valv baro ki'n ganny sele dir i ganny fer avek bann metal tel ki stainless steel.
2. Soft seal: Sa per seal i ganny fer avek materyo metal lo en kote e materyo non-metal elastik lo lot kote, ki apel “soft seal”. sa kalite sele i annan en bon performans sele, me i pa rezistan avek tanperatir o, i fasil pou mete, e i annan bann move propriyete mekanik. par egzanp: lastik an feray; tetrafluoroethylene an feray, eksetera. par egzanp, sa sez elastik enportevalv baroe of VTON i zeneralman ganny servi a en tanperatir mwens ki 100°C, e i plizoumwen ganny servi pou delo tanperatir lasanm.
3. sele dir: sa per sele i ganny fer avek materyo metal oubyen lezot materyo pli dir lo tou le de kote, ki apel “sele dir”. sa kalite sele i annan en move performans sele, me i rezistan a tanperatir o, dega e i annan bann bon propriyete mekanik. Par egzanp: feray feray; kwiv an feray; grafit an feray; feray alyaj feray; (sa feray isi i kapab osi feray fonte, feray fonte, lasye alye i kapab osi sirfas, alye ki'n ganny spray). par egzanp, valv baro an feray enporte VTON i kapab ganny servi pou vapeur, gas, delwil ek delo, eksetera.
2. Teknolozi konstriksyon
lanvironnman misyon lendistri masin i konpleks, bokou ladan i tanperatir tre ba e presyon ba, avek en gran rezistans e korozivite for sa medyom. aprezan teknolozi in amelyore, alor bann valv baro fermen dir in ganny promouvwar bokou.
relasyon dir ant bann metal i devret ganny pran an kont. anfet, sa valv baro ki'n ganny sele dir i parey sa enn ki'n ganny sele dou akoz i en sele ant bann metal. Lekor valv i bezwen ganny redi, e plak valv ek sez valv i bezwen ganny kontinyelman kraze pou ganny sele. sikl prodiksyon bann valv baro ki'n ganny sele dir i long.
3. Kondisyon servi
lefe sele bann sele mou i kapab ariv zero fwit, tandis ki bann sele dir i kapab o ou ba dapre bann legzizans;
bann sele mou i bezwen rezistan a dife, e fwit pou arive a bann tanperatir o, tandis ki bann sele dir pa pou koule. bann sele dir valv fermtir dirzans i kapab ganny servi anba presyon o, tandis ki bann sele mou pa kapab ganny servi. a sa moman, valv baro fermen VTON i neseser.
bann sele mou pa devret ganny servi lo serten medya korozif, e bann sele dir i kapab ganny servi;
4. Kondisyon loperasyon
bann sele dir i kapab o ou ba dapre bann legzizans; bann sele mou i bezwen rezistan a dife, e bann sele mou i kapab atenn bann sele endividyel o. akoz a bann tanperatir tre ba, bann sele mou pou koule, tandis ki bann sele dir napa sa problenm; bann sele dir i zeneralman kapab tenir bann presyon tre o, tandis ki bann sele mou pa kapab. par egzanp, bann valv an feray forze enporte VTON i servi bann sele dir, e presyon i kapab ariv 32Mpa ou 2500LB; bann sele mou pa kapab ganny servi dan serten landrwa akoz koule sa medyom, tel ki serten medya korozif); finalman, bann valv hard seal i zeneralman pli ser ki bann soft seal. konsernan konstriksyon, diferans ant le de pa gran, diferans prensipal se sez valv, sele mou i non-metalik, e sele dir i metal
V. seleksyon lekipman
seleksyon sele mou ek dirvalv baroi prensipalman baze lo medyom prosesis, tanperatir ek presyon. zeneralman, si sa medyom i annan bann partikil solid oubyen i annan deteryorasyon oubyen tanperatir i pli o ki 200 degre, i pli bon pou servi bann sele dir. par egzanp, vapeur o tanperatir i zeneralman anviron 180-350℃, alor en valv baro sele dir i bezwen ganny selekte.
6. Diferans dan pri ek kou
pour menm kalib, presyon ek materyo, enporte hard-sealedvalv baroi bokou pli ser ki bann soft-sealed gate valve enporte; par egzanp, VTON's DN100 enporte cast steel gate valve i 40% pli ser ki DN100 enporte cast steel soft-sealed gate valve; si tou le de valv baro fermen dir ek valv baro sele dou i kapab ganny servi anba bann kondisyon travay, ler ou pe konsider kou, esey swazir valv baro sele dou enporte.
7. Diferans dan lavi servis
sele mou i vedir ki en kote sa per sele i ganny fer avek en materyo avek en dir relativman ba. an zeneral, sa sez sele mou i ganny fer avek bann materyo non-metalik avek serten lafors, dir ek rezistans tanperatir. i annan en bon performans sele e i kapab ariv zero fwit, me son lavi ek adaptabilite avek tanperatir i relativman move. bann sele dir i ganny fer avek metal e i annan en performans sele relativman move, menm si serten fabrikan i reklanmen ki zot kapab ganny zero fwit.
lavantaz bann sele mou se bon performans sele, e dezavantaz se vyeisman fasil, deteryorasyon, e lavi servis kourt. bann sele dir i annan en lavi servis ki long, me zot performans sele i relativman move konpare avek bann sele mou. sa de kalite sele i kapab konplemant kanmarad. an term sele, bann sele mou i relativman pli meyer, me aprezan sele bann sele dir i osi kapab zwenn bann legzizans korespondan.
bann sele mou pa kapab zwenn bann legzizans prosesis pou serten materyo korozif, me bann sele dir i kapab rezourd sa problenm!
sa de kalite sele i kapab konplemant kanmarad. an term sele, bann sele mou i relativman pli bon, me aprezan sele bann sele dir i osi kapab zwenn bann legzizans korespondan!
lavantaz bann sele mou se bon performans sele, e dezavantaz se vyeisman fasil, deteryorasyon, e lavi servis kourt.
bann sele dir i annan en lavi servis ki long, me sele i relativman pli pir ki bann sele mou.
