Isimiso sokusebenza kwe-valve, ukuhlukaniswa kanye nezinyathelo zokuqapha zokufakwa

Indlela i-check valve esebenza ngayo

Iivalvu yokuhlola isetshenziswa ohlelweni lwamapayipi, futhi umsebenzi wayo oyinhloko ukuvimbela ukugeleza emuva kwe-medium, ukujikeleza okuphambene kwephampu kanye nenjini yayo yokushayela, kanye nokukhishwa kwe-medium esitsheni.

Hlola ama-valve ingasetshenziswa futhi emigqeni ehlinzeka ngezinhlelo ezisizayo lapho ingcindezi ingakhuphuka ngaphezu kwengcindezi yesistimu eyinhloko. Ama-valve okuhlola angasetshenziswa kumapayipi emidiya ehlukahlukene ngokwezinto ezahlukene.

I-valve yokuhlola ifakwa epayipini futhi iba ngenye yezingxenye zoketshezi zepayipi eliphelele. Inqubo yokuvula nokuvala idiski yevalvu ithintwa yisimo sokugeleza kwesikhashana kwesistimu lapho itholakala khona; izici zokuvala zediski yevalvu zithi Inomthelela esimweni sokugeleza koketshezi.

Ukuhlukaniswa kwevalvu yokuhlola

1. I-valve yokuhlola i-swing

Idiski yevalvu yokuhlola ukujiya isesimweni sediski futhi ijikeleza umgodi wesiteshi sesihlalo sevalvu. Ngenxa yokuthi isiteshi esisevalvinini silula, ukumelana kokugeleza kuncane kunokwevalvu yokuhlola ukuphakama. Ifanele amazinga okugeleza aphansi kanye nezinguquko ezingavamile ekugelezeni. Kodwa-ke, ayifanele ukugeleza okunamandla, futhi ukusebenza kwayo kokuvala akukuhle njengohlobo lokuphakamisa.

I-valve yokuhlola i-swing ihlukaniswe ngezinhlobo ezintathu: uhlobo lwe-single-lobe, uhlobo lwe-double-lobe kanye nohlobo lwe-multi-lobe. Lezi zinhlobo ezintathu zihlukaniswe ngokuyinhloko ngokobubanzi be-valve.

2. I-valve yokuhlola ukuphakamisa

I-valve yokuhlola lapho i-valve ishelela khona eceleni komugqa oqondile womzimba we-valve. I-valve yokuhlola ukuphakama ingafakwa kuphela epayipini elivundlile, futhi ibhola lingasetshenziswa kwi-valve yokuhlola ukuphakama kwe-valve encane enobukhulu obuphezulu. Isimo somzimba we-valve yokuhlola ukuphakama sifana nese-valve yomhlaba (ingasetshenziswa ngokufana ne-valve yomhlaba), ngakho-ke i-coefficient yayo yokumelana noketshezi inkulu. Isakhiwo sayo sifana ne-valve yomhlaba, futhi umzimba we-valve ne-disc kufana ne-valve yomhlaba.

3. I-valve yokuhlola ubhathane

Ivalvu yokuhlola lapho idiski ijikeleza khona iphini esihlalweni. Ivalvu yokuhlola idiski inesakhiwo esilula futhi ingafakwa kuphela epayipini elivundlile, futhi ukusebenza kokuvala kubi.

4. I-valve yokuhlola ipayipi

Ivalvu lapho idiski ishelela khona eceleni komugqa ophakathi womzimba wevalvu. Ivalvu yokuhlola ipayipi iyivalvu entsha. Incane ngobukhulu, isisindo esincane futhi inhle ekucubunguleni ubuchwepheshe. Ingenye yezindlela zokuthuthukiswa kwevalvu yokuhlola. Kodwa-ke, i-coefficient yokumelana noketshezi inkulu kancane kunevalvu yokuhlola i-swing.

5. I-valve yokuhlola ukucindezela

Lolu hlobo lwevalvu lusetshenziswa njengevalvu yokuphakelwa kwamanzi neyokusika umusi, lunomsebenzi ohlanganisiwe wevalvu yokuhlola ukuphakama kanye nevalvu yomhlaba noma ivalvu ye-angle.

Ngaphezu kwalokho, kunezinye izivalo zokuhlola ezingafanele ukufakwa kwepayipi lokukhipha amanzi, njenge-valve yonyawo, uhlobo lwesipilingi, uhlobo lwe-Y, njll.
