Isimiso nokuhlukaniswa kwama-valve okulawula

I-valve yokulawula iyithuluzi elivamile lokulawula ukugeleza kwamanzi, elisetshenziswa kabanzi embonini, amakhemikhali, e-petroleum, emanzini ampompi, igesi yemvelo kanye neminye imikhakha. I-valve elawulayo isekelwe esimisweni sokulawulwa kokucindezela okuhlukile, okwenza ukugeleza koketshezi kufinyelele inani elinqunywe kusengaphambili ngokulawula ukucindezelwa okuhlukile kokuphakathi. I-valve elawulayo ingaphinde iguqule imingcele yesistimu yokulawula ukuze ibone ukulungiswa kokugeleza, izinga le-liquid, izinga lokushisa kanye neminye imingcele, ukuze kubonakale ukulawula okuzenzakalelayo kwenqubo.

Ukuhlukaniswa kwama-valve alawulayo kungahlukaniswa ngezinhlobo eziningi ngokuya ngezimo ezihlukene zokusebenza, njengoba kukhonjisiwe ngezansi:

1. I-valve yokulawula ukucindezela: isetshenziselwa ukulungisa ingcindezi epayipini, esetshenziswa kakhulu embonini yamakhemikhali, i-petroleum neminye imikhakha.

I-valve yokulawula izinga lokushisa engu-2: ilungele ukulungisa izinga lokushisa le-medium, elivamile ezinhlelweni zamanzi ashisayo, ama-heaters, njll.

3. I-valve yokulawula izinga likaketshezi: isetshenziselwa ukufeza ukulawulwa kwezinga le-liquid kanye nomthethonqubo, evame ukusetshenziswa ekwelapheni kwamanzi, embonini yamakhemikhali neminye imikhakha.

I-valve yokulawula ukugeleza kwe-4: ikakhulukazi esetshenziselwa ukulungisa ukugeleza kwepayipi, esetshenziswa kabanzi kumakhemikhali, ekhemisi, ekudleni nakweminye imikhakha.

5. I-valve yokulawula isiqondiso: isetshenziselwa ukulungisa isiqondiso sokugeleza koketshezi, ngokuvamile esetshenziselwa ukusebenza kwe-shunt kanye ne-confluence.

Ngokwamafomu ahlukene wesakhiwo, ama-valve okulawula angahlukaniswa abe yizinhlobo ezilandelayo:

1. I-valve yokulawula yohlobo lwesango: yenziwe ngenqama ehambayo kanye ne-gasket. Lapho inqama ihamba nge-axis perpendicular ukuya lapho kugeleza uketshezi, indawo yesiteshi ingashintshwa, ngaleyo ndlela iguqule usayizi wokugeleza.

2. Isilawuli sohlobo lwe-diaphragm: esakhiwe nge-diaphragm, isihlalo kanye nendlela yokushayela kanye nezinye izingxenye. Uma i-diaphragm ingaphansi kwengcindezi emaphakathi, ingena esihlalweni ukuze ivimbele ukuvuza okuphakathi, ngaleyo ndlela izuze ukulawula ukugeleza.

I-valve yokulawula umoya we-3: eyakhiwe ngesilinda segesi, i-valve yokulawula igesi kanye nendlela yokusebenza nezinye izingxenye. I-piston ne-disc kususwa eduze kwe-eksisi ngokufaka amasignali ahlukene wengcindezi ukuze kuzuzwe ukulawula ukugeleza.

4. I-valve yokulawula kagesi: eyakhiwe nge-motor, i-reducer, i-clutch, i-valve, insimbi yokulawula nezinye izingxenye. Ngokujikeleza kwekhava ye-motor drive valve, ukugeleza kungalungiswa.

Ngokuvamile, i-valve elawulayo ekulawuleni izimboni, ukulawulwa kwenqubo kanye nezinkambu zokuphepha nezinye izici zinezinhlobonhlobo zezicelo, izinhlobonhlobo zayo, kancane kancane zibheke ezihlakaniphile, ezizenzekelayo, ukuthuthukisa ukusebenza kahle kokukhiqizwa kwezimboni, ukunciphisa ukungcoliswa kwemvelo nokuvikela ukuphepha kwabasebenzi kanye nezinye izici ukubaluleka okubalulekile.
