Bokangami ya soupape ezali eteni ya ntina ya soupape mobimba, ntina na yango ya monene ezali ya kopekisa fuite, .valve oyo ezali na katikiti ya bokangami babengaka yango pe bague ya bokangami, ezali ebongiseli oyo ezali directement na contact na milieu oyo ezali na pipeline mpe epekisaka moyen ekende koleka. Tango valve ezali kosalelama, ezali na ba médias ndenge na ndenge na pipeline, lokola liquide, gaz, mafuta, ba milieux corrosifs, etc., mpe ba joints ya ba soupapes ndenge na ndenge esalelamaka na bisika ndenge na ndenge mpe ekoki ko s’adapter na ba milieux ndenge na ndenge.
TWSValveekundolisi yo ete biloko ya ba joints ya soupape ekoki kokabolama na biteni mibale, elingi koloba biloko ya bibende mpe biloko oyo ezali bibende te. Mingimingi basalelaka ba joints oyo ezali ya bibende te na ba tuyaux na température mpe pression normale, nzokande ba joints ya bibende ezali na ba applications ya monene mpe ekoki kosalelama na température ya likolo. pression makasi.

Ezali na ntina te°C, caoutchouc naturel ezali t≤60°C, mpe caoutchouc esalelamaka mpo na kokanga ba soupapes ya globe, ba soupapes ya porte, ba soupapes ya diaphragme, ba soupapes ya papillon, ba soupapes ya contrôle, ba soupapes ya pinch mpe ba soupapes mosusu oyo ezali na pression nominale PN≤1MPa.
2. Nylon oyo ezali na kati
Nylon ezali na bizaleli ya coefficient ya friction ya moke mpe résistance ya malamu na corrosion. Nylon esalelamaka mingi pona ba soupapes ya boule na ba soupapes ya globe na température t≤90°C mpe pression nominal PN≤32MPa.
3. Polytétrafluoroéthylène oyo ezali na kati
PTFE esalelamaka mingi pona ba soupapes ya globe, ba soupapes ya porte, ba soupapes ya boule, etc. na température t≤232. Ezali na ntina te°C mpe pression moko ya nominal PN≤6,4MPa.
4. Ebende ya kobwaka
Fonte esalelamaka pona ba soupapes ya porte, ba soupapes ya globe, ba soupapes ya fiche, etc. pona température t≤100. Ezali na ntina te°C, pression nominale PN≤1.6MPa, gaz mpe petrole.
5. Alliage ya Babbitt
Babbitt alliage esalelamaka mpo na valve globe d'ammonia na température t-70 ~ 150°Cmpe pression nominale PN≤2,5MPa ya.
6. Alliage ya cuivre
Biloko oyo basalelaka mingi mpo na kosala ba alliages ya cuivre ezali bronze ya étain 6-6-3 mpe cuivre manganèse 58-2-2. Alliage ya cuivre ezali na résistance ya kolata malamu mpe ebongi mpo na mayi mpe vapeur na température t≤200. Ezali na ntina te°Cmpe pression nominale PN≤1,6MPa. Mbala mingi esalelamaka na ba soupapes ya porte, ba soupapes ya globe, ba soupapes ya contrôle, ba soupapes ya fiche, etc.
7. Chrome ya bibende oyo epɔlaka te
Ba grades ya acier inoxydable chrome oyo basalelaka mingi ezali 2Cr13 na 3Cr13, oyo esili ko boma pe ko temper, pe ezali na résistance ya malamu na corrosion. Mbala mingi esalelamaka na ba soupapes ya mayi, vapeur na pétrole na température t≤450. Ezali na ntina te°Cmpe pression nominale PN≤32MPa.
8. Chrome-nickel-titane acier inoxydable
Grade oyo basalelaka mingi ya acier inoxydable chrome-nickel-titane ezali 1Cr18Ni9ti, oyo ezali na résistance ya malamu na corrosion, résistance na érosion mpe résistance na chaleur. Ebongi mpo na vapeur mpe na ba médias mosusu oyo ezali na température t≤600°C mpe pression moko ya nominal PN≤6.4MPa, mpe esalelamaka mpo na ba soupapes ya globe, ba soupapes ya boule, etc.
9. Bibende oyo ezali na nitrage
Grade oyo basalelaka mingi ya acier nitrage ezali 38CrMoAlA, oyo ezali na résistance ya malamu na corrosion mpe résistance na ba rayures sima ya traitement ya carburation. Mbala mingi esalelamaka na ba soupapes ya porte ya centrale électrique na température t≤540. Ezali na ntina te°Cmpe pression nominale PN≤10MPa.
10. Kosala boronisation
Boronisation esalaka directement surface ya scellage à partir ya matériel ya nzoto ya valve to nzoto ya disque, et puis esalaka traitement ya surface ya boronizing. Surface ya scellage eza na résistance ya bien ya kolata. Pona soupape ya souffle ya centrale électrique.
Ntango bazali kosalela valve, makambo oyo esengeli kotya likebi ezali boye:
1. Esengeli komeka ndenge oyo valve ekangamaka mpo na koyeba soki ezali kosala malamu.
2. Tala soki esika ya kokanga ya valve elati, mpe bongisa to zongisa yango engebene na likambo.
