Ama-valve ebhola nama-valve esango ayizinhlobo ezimbili ezivamile zama-valve, futhi anomehluko omkhulu ngesakhiwo, isimiso sokusebenza, kanye nezimo zokusetshenziswa. Nansi incazelo yomehluko:
Okokuqala, umehluko wesakhiwo
1. I-valve yebhola:
- I-Spool: Ibhola elinembobo phakathi lisetshenziswa njengesikhungo se-valve, futhi ibhola liyajikeleza ukulawula ukuvulwa nokuvalwa kwe-valve.
- Uphawu: Ibhola nesihlalo kwakha uphawu, ukusebenza kophawu kuhle, kufanelekile ekucindezelweni okuphezulu, ekushiseni okuphezulu nakwezinye izindawo ezinzima.
- Ukusebenza: Jikelezisa ibhola ngama-degree angu-90 ukuze kutholakale ukuvulwa nokuvalwa kwevalvu, ukusebenza okulula nokusheshayo.
2. I-valve yesango:
- Umongo wevalvu: Umzimba wevalvu unepuleti eliyisicaba (inqama) eliqonde ngqo ohlangothini lokugeleza kwe-medium, elilawula ukuvulwa nokuvalwa kwevalvu ngokuphakamisa inqama.
- Ukuvalwa: Kwakhiwa uphawu phakathi kwesango nesihlalo, kodwa ukusebenza kokuvalwa kwevalvu yesango kuthinteka kakhulu ukunemba kokucubungula kwesango nesihlalo.
Ukusebenza: Ukuvulwa nokuvalwa kwevalvu yesango kudinga ukuthi isango lihambe liye phezulu naphansi ngendlela yokugeleza kwe-medium, futhi ukusebenza kuhamba kancane futhi kuyakhathaza.
Okwesibili, isimiso sokusebenza
1. I-valve yebhola:
- Ingxenye yokuvula nokuvala (ibhola) iqhutshwa yisiqu sevalvu futhi ijikeleza i-axis yevalvu yebhola, futhi ukuvulwa nokuvalwa kwevalvu kungabonakala ngokujikeleza ama-degrees angu-90.
Esimweni sokuvalwa, ivalvu yebhola yakha uphawu lwensimbi phakathi kwebhola nesihlalo, futhi ukusebenza kokuvala kuthembekile.
2. I-valve yesango:
- Isango liya phezulu naphansi ngendlela yokugeleza kwe-medium. Ivalvu iyavuleka lapho isango liphakama futhi livaleka lapho isango liwa.
- Uma i-valve yesango ivaliwe, kwakheka uphawu phakathi kwepuleti yesango nesihlalo, kodwa ukusebenza kokuvala kuthinteka kakhulu ukunemba kokucubungula kwepuleti yesango nesihlalo.
Okwesithathu, sebenzisa isimo
1. I-valve yebhola:
- Isetshenziswa kabanzi kuphethiloli, amakhemikhali, ukukhiqizwa kukagesi, ukwenziwa kwephepha, amandla enuzi, izindiza, amarokhethi kanye neminye imikhakha kanye nokuphila kwansuku zonke komphakathi.
- Ifaneleka kakhulu ekuvuleni nasekuvaleni okusheshayo, izidingo zokusebenza kokuvala okuphezulu, ukucindezela okuphakathi kuyimicimbi emikhulu.
2. I-valve yesango:
- Isetshenziswa kakhulu ukunqanda ukugeleza kwemidiya, futhi ivame kakhulu kuma-valve okulawula ayinhloko amapayipi okushisa kanye namapayipi okuhambisa amanzi kanye nawokukhipha amanzi.
- Ivalvu yesango inokumelana okuncane kanye nokuvala okuqinile, kodwa isivinini sokuvula nokuvala sihamba kancane, futhi ayifaneleki ngezikhathi lapho kudingeka khona ukuvulwa nokuvala njalo.
Okwesine, eminye imehluko
1. Ukusebenza kokulungisa:
Ukusebenza kokulungiswa kwevalvu yebhola kuphansi kakhulu, ikakhulukazi kusetshenziselwa ukusika noma ukuxhuma i-medium epayipini.
- Nakuba i-valve yesango inomsebenzi othile wokulungisa, isengozini yokuguguleka kwemidiya kanye nokudlidliza lapho ivuliwe kancane, okuholela ekulimaleni kwendawo yokuvala.
2. Ubunzima bokulungisa:
- Isakhiwo se-ball valve silula, sisebenza kahle kakhulu ekuvaleni, futhi silula kakhulu ukugcinwa.
- Isakhiwo se-valve yesango siyinkimbinkimbi kakhulu, futhi umsele wesihlalo kulula ukufaka izinto eziqinile, okunzima ukuzinakekela.
Ngamafuphi, kunomehluko osobala phakathi kwama-ball valve nama-gate valve ngokwesakhiwo, isimiso sokusebenza kanye nesimo sokusetshenziswa. Lapho ukhetha i-valve, uhlobo lwe-valve olufanele kufanele lukhethwe ngokuya ngezimo zokusebenza ezithile kanye nezidingo eziphakathi.
