Guide ya fonctionnement & application ya joint ya valve

Ba joints ya soupapes esalemi mpo na kopekisa ba fuites oyo euti na pression, corrosion, mpe expansion/contraction thermique entre ba composants. Alors que presque nionso ezalaki na brideboyokani’ .s ba soupapes esengaka ba joints, application spécifique na yango mpe importance ekeseni na type ya soupape mpe design. Na eteni oyo, .TWSekolimbola ba positions ya installation ya soupapes na sélection ya matériel ya joint.

I. Application ya liboso ya ba joints ezali na articulation ya bride ya ba connexions ya soupapes.

Valve ya usage oyo emonanaka mingi

1. Valve ya Porte
2. Valve ya Globe
3. Valve ya papillon(surtout valve ya papillon bride concentrique mpe double excentrique)
4. Valve ya vérification

Na ba soupapes wana, joint esalelamaka te pona régulation ya débit to scellage na kati ya soupape yango moko, kasi e installer entre deux brides (entre bride ya soupape yango moko na bride ya tuyau). Na kokanga ba boulons makasi, nguya ya kokanga ekoki mpo na kosala sceau statique, kopekisa fuite ya milieu na connexion. Mosala na yango ezali ya kotondisa ba petits espaces inégales entre ba surfaces mibale ya bride ya métal, ko assurer 100% scellement na connexion.

II.Kosalela Joint na Valve “Couvercle ya soupape” .

Ba soupapes mingi esalemi na nzoto ya ba soupapes mpe ba couvercles ekeseni mpo na entretien ya kati ya pete (ndakisa, kozongisa ba sièges ya soupapes, ba soupapes ya disque, to ko dégager ba débris), oyo na sima ekangami na boulon. Esengeli mpe na joint na connexion oyo mpo na ko assurer sceau serré.

1. Mbala mingi, boyokani kati na ezipeli ya valve mpe nzoto ya valve ya valve ya porte mpe valve ya globe esɛngaka mbala mingi kosalela joint to O-ring.
2. Joint oyo ezali na position oyo esalaka mpe lokola sceau statique mpo na kopekisa milieu e fuite longwa na nzoto ya valve na atmosphère.

III. Joint spécial mpo na ba types spécifiques ya soupapes

Ba soupapes mosusu ekɔtisaka joint lokola eteni ya ensemble na yango ya bokangami ya noyau, oyo ebongisami mpo na kosangisa na kati ya structure ya soupape.

1. Valve ya papillon-joint ya kiti ya soupape

• Kiti ya valve ya papillon ezali mpenza joint ya bague, oyo efinamaka na efelo ya kati ya nzoto ya valve to batyaka zingazinga ya disque ya papillon.
• Tango papillondisqueekangami, efinaka joint ya kiti ya valve mpo na kosala sceau dynamique (lokola papillondisqueebalukaka).
• Matériel ezali typiquement caoutchouc (par exemple, EPDM, NBR, Viton) to PTFE, oyo esalemi pona ko accueillir ba médias ndenge na ndenge pe ba conditions ya température.

2. Valve ya boule-Jonette ya Siège ya soupape

• Kiti ya valve ya valve ya boule ezali mpe lolenge moko ya joint, oyo esalemaka mingi na biloko lokola PTFE (polytetrafluoroéthylène), PEEK (polyetherethercétone), to ba plastiques renforcées.
• Ezali kopesa ekanga kati na boule mpe nzoto ya valve, esalaka lokola ekangami ya statique (na boyokani na nzoto ya valve) mpe ekangami ya dynamique (na boyokani na boule oyo ezali kobaluka).

IV. Ba valve nini basalelaka mingi mingi te na ba joints?

1. Ba soupapes soudées: Nzoto ya soupape e soudé mbala moko na pipeline, yango esali que ezala na besoin ya ba brides na ba joints te.
2. Ba soupapes oyo ezali na ba connexions filetées: Mingimingi basalelaka ba filées (na ndakisa ruban ya matière première to scellant), mingimingi elongolaka mposa ya ba joints.
3. Ba soupapes monolithiques: Ba soupapes mosusu ya boule ya talo moke to ba soupapes spécialisées ezali na nzoto ya soupape intégrale oyo ekoki ko démonter te, na yango ezangi joint ya couvercle ya soupape.
4. Ba soupapes oyo ezali na ba bagues O to ba joints enveloppés na métal: Na ba applications ya pression makasi, ya température makasi, to ya moyenne spécial, ba solutions ya scellage ya avancement ekoki ko remplacer ba joints conventionnels non métalliques.

V. Bokuse ya koloba:

Joint ya soupape ezali lolenge moko ya élément ya scellage ya clé ya kokata générale, esalemaka mingi na connexion ya pipeline ya ba soupapes ya bride ndenge na ndenge, mpe esalelamaka pe na scellage ya couvercle ya soupape ya ba soupapes ebele. Na sélection, esengeli pona matériel ya joint oyo ebongi pe forme selon type ya soupape, mode ya connexion, milieu, température na pression.
