1. Ba soupapes ya ndako mpe ya kofanda (lokola ba soupapes ya mayi ya robinet mpe ya gaz) .
Media: Mai ya peto ya robinet, gaz naturel (non-corrossive)
Ba conditions ya fonctionnement: Pression ya nse ( Moke to ekokani na 1 MPa), température ya chambre (-10 degrés à 60 degrés )
Matériel: Cuivre, fonte, plastique (PPR, PVC)
Bomoi ya bomoi: Mbula 10-20
Ba soupapes ya cuivre (lokola ba soupapes ya boule ya cuivre) ezali très résistantes na corrosion-mpe ekoki kowumela mbula koleka 20 soki ba entretien malamu.
Ba soupapes ya fer fonte ekoki kozala na rouille. Soki mayi ezali malamu te (ezali na bosoto mpe bosoto), ekoki kokangama to kotanga nsima ya mibu soko 10.
Ba soupapes ya plastique ezo affecter mingi na température. Kozala ntango molai na pole ya moi mbala moko to na molunge makasi ekoki kosala ete moto akóma mobange nokinoki, mpe yango ekoki kosala ete bomoi na bango ezala mokuse tii na mbula 5-10.
2. Ba soupapes ya état de travail général industriel (lokola mayi, vapeur, systèmes ya mafuta) .
Moyen : mayi ya peto, vapeur saturé, mafuta ya minerais (moins de corrosif)
Conditions de travail: pression moyenne et basse (1 ~ 10MPa), température moyenne ( Moins que to ekokani na 200)
Matériel: acier fonte (WCB), acier inoxydable (304), fer ductile
Bomoi: 8 ~ 15 mbula
Ba joints (lokola caoutchouc, polytétrafluoroéthylène) ezali ba parties ya kolata. Soki bazongisaka yango mbala na mbala, nzoto ya valve ekoki kobakisama tii mbula koleka 15;
Ba soupapes ya vapeur ezali prone ya kolata mpo na alternance mbala na mbala ya molunge mpe malili, mpe surface ya kokangama ezali pete kolata, mpe bomoi ekoki kozala mokuse na 5 ~ 8 ans.
3. Ba soupapes ya état de travail corrosif/ya makasi (lokola acide, alcali, na milieu oyo ezali na ba particules) .
Moyen : solution acide na alcalin, mayi ya mbu, potopoto, mayi ya bosoto ya zelo
Conditions ya mosala: pression moyenne mpe ya likolo ( Moke to ekokani na 20MPa), température ya likolo (200~400) to température ya nse ( Moke to ekokani na -20)
Matériel: acier inoxydable résistant na corrosion-(316), Hastelloy, fluor-dovré (PTFE)
Bomoi: 3 ~ 10 mbula
Soki milieu ezali na corrosion makasi (lokola acide chlorhydrique, chlore), ata soki basaleli biloko oyo ekoki kozala na corrosion-resistants, surface ya sceau mpe nzoto ya valve eko corrosion mokemoke, mpe vie ya service ekoki kozala kaka 3~5 ans;
Moyen oyo ezali na ba particules (lokola bosoto, mayi ya bosoto) eko éroder kiti ya soupape na noyau ya soupape, eko accélérer kolata, mpe vie ya service ezali mingi mingi 3 ~ 8 ans.
4. Ba soupapes pona ba conditions ya service critique ya pression makasi, ya température ya likolo- (ndakisa, ba centrales électriques, ba tuyaux chimiques ya pression makasi-) .
Media: Vapeur ya pression makasi, mafuta ya moto ya température ya likolo-, gaz ya pression makasi
Conditions ya fonctionnement: Pression makasi ( Monene koleka to ekokani na 10 MPa), température ya likolo ( Monene koleka to ekokani na 400 degrés )
Matériel: Acier structurel en alliage (par exemple, acier Cr-Mo), acier inoxydable forgé
Bomoi ya bomoi: Mbula 5-10
Konyokwama na mpasi makasi ya ntango molai, érosion ya ba médias, mpe corrosion oxidative, ba noyaux ya soupapes mpe bakiti ekoki kobukana mpe esengaka botali mbala na mbala (ndakisa, bomekoli ya ultrasons). Mingimingi, bomoi eleki mbula 10 te.
Makambo ya ntina oyo ezali na bopusi:
Bobateli: Kopakola mafuta mbala na mbala, bopeto, mpe kozongisa ba joints (ndakisa, O-rings, emballage) ekoki kobakisela bomoi ya valve na 30%-50%.
Mbala ya mosala : Ba soupapes oyo efungwamaka mpe ekangamaka mingi (ndakisa, mbala ebele na mokolo) ekutanaka na kolata nokinoki na bisika ya bokangami, oyo esalaka ete bomoi ezala ata 50% mokuse koleka ba soupapes oyo esalelamaka mingi te (mwa mbala na sanza).
