Hlola umgomo wokusebenza we-valve, ukuhlukaniswa kanye nokufaka izinyathelo zokufaka

I-CheckVVE isebenza kanjani

Le khasiBheka i-valve isetshenziswa ohlelweni lwamapayipi, futhi umsebenzi wayo oyinhloko ukuvikela ukubuyela emuva kwe-medium, ukujikeleza okubuyela emuva kwepompo nemoto yayo yokushayela, nokukhishwa okuphakathi esitsheni.

Bheka ama-valves Ingase futhi isetshenziswe emigqeni enikezela ngezinhlelo ezisizayo lapho ingcindezi ingavuka khona ngaphezu kwengcindezi yesistimu eyinhloko. Ama-valves ahlole angasetshenziswa kumapayipi abezindaba ahlukahlukene ngokuya ngezinto ezahlukahlukene.

I-valve yesheke ifakiwe kwipayipi futhi iba ngomunye wezakhi zamanzi zepayipi eliphelele. Inqubo yokuvula nokuvala ye-Valve Disc ithinteka isimo sokugeleza kwesikhashana sohlelo lapho itholakala khona; Futhi, izici zokuvala ze-valve disc zinomthelela esimweni sokugeleza koketshezi.

Hlola ukuhlukaniswa kwe-valve

1. Swing hlola i-valve

I-disc ye-Swing Check valve isesimweni se-disc futhi ijikeleze ezungeze i-shaft yesiteshi sesihlalo se-valve. Ngoba isiteshi esiku-valve sithuthukisiwe, ukumelana nokugeleza kuncane kunalokho kwe-lift Check Valve. Ilungele amanani aphansi okugeleza kanye nezinguquko ezingejwayelekile zokugeleza. Kodwa-ke, akufanelekile ukugeleza okudonswayo, futhi ukusebenza kwalo kokuvalwa akukuhle njengonohlobo lokuphakamisa.

I-Swing Check valve ihlukaniswe ngezinhlobo ezintathu: uhlobo lwe-lobe-lobe, uhlobo oluphindwe kabili lwe-lobe nohlobo lwe-multi-lobe. Lezi zindlela ezintathu zihlukaniswe ikakhulu nge-valve ububanzi.

2. Phakamisa i-valve yokuhlola

I-valve yesheke lapho i-valve disc islayida emugqeni omile womzimba we-valve. I-valve yokuhlola ephakeme ingafakwa kuphela epayipini evundlile, futhi ibhola lingasetshenziselwa i-valve disc ku-valve ye-sheck-yobubanzi obukhulu. Ukwakheka komzimba we-valve we-lift Check Valve kuyafana nalokho kwe-valve ye-Globe Valve (kungasetshenziswa kufana ne-globe valve), ngakho-ke i-coffient yayo yokumelana namanzi inkulu kakhulu. Isakhiwo saso sifana ne-valve ye-Globe Valve, futhi umzimba we-valve ne-disc afana ne-valve ye-hlaba.

3. Uvemvane uhlola i-valve

I-valve yokuhlola lapho i-disc ijikeleza nge-PIN esihlalweni. I-valve yokuhlola i-disc inesakhiwo esilula futhi ingafakwa kuphela epayipini evundlile, futhi ukusebenza kokubekwa uphawu kumpofu.

4. Ipayiphu ehlola i-valve

I-valve lapho i-disc islayida khona lapho uphakathi nendawo yomzimba we-valve. I-Pipeline Check valve iyi-valve entsha. Kuncane ngosayizi, ukukhanya ngesisindo nokuhle kubuchwepheshe obucubungula. Ngenye yezinkomba zokuthuthukisa i-valve ye-Check Valve. Kodwa-ke, i-couffient emelana noketshezi ikhulu kakhulu kunaleyo ye-valve yokuhlola yokuswayipha.

I-5. Ukucindezela Ukuhlola i-valve

Lolu hlobo lwe-valve lusetshenziswa njenge-boiler feed manzi ne-steam cut-off valve, inomsebenzi ohlanganisiwe wokuphakamisa i-valve ne-valve ye-globe noma i-angle valve.

Ngaphezu kwalokho, kunama-valves athile angafanele ukufakwa kokukhipha amampunge, njenge-valve yonyawo, uhlobo lwentwasahlobo, uhlobo lwe-y, njll.
