Amavalvu esango namavalvu ebhabhathane angamavalvu amabili asetshenziswa kakhulu. Ahluke kakhulu ngokwezakhiwo zawo, izindlela zokusebenzisa, kanye nokuzivumelanisa nezimo zokusebenza. Lesi sihloko sizosiza abasebenzisi ukuthi baqonde kangcono umehluko phakathi kwamavalvu esango namavalvu ebhabhathane. Siza abasebenzisi kangcono ukuthi bakhethe amavalvu.
Ngaphambi kokuchaza umehluko phakathi kwe-valve yesango ne-valve ye-butterfly, ake sibheke izincazelo zazo zombili. Mhlawumbe ungathola umehluko phakathi kwazo ngokucophelela encazelweni.
I-valve yesango,njengoba igama lisikisela, ingasika i-medium epayipini njengesango, futhi uhlobo lwe-valve esiyisebenzisa sonke ekukhiqizeni nasekuphileni. Ingxenye yokuvula nokuvala ye-valve yesango ibizwa ngokuthi isango, futhi isango liya phezulu naphansi, futhi isiqondiso salo sokunyakaza siqonde ngqo esiqondisoni sokugeleza kwe-medium epayipini loketshezi; i-valve yesango iyi-valve enqunyiwe, engavulwa ngokugcwele noma ivalwe ngokuphelele, futhi ukugeleza akukwazi ukulungiswa.
I-valve ye-Butterfly, eyaziwa nangokuthi i-flap valve.Ingxenye yayo yokuvula nokuvala iyipuleti lebhabhathane elimise okwediski, elinamathele esiqwini sevalvu futhi lijikeleza esiqwini sevalvu ukuze kufezwe ukuvulwa nokuvalwa. Indlela yokuhamba kwevalvu yebhabhathane iwukuzungeza endaweni, futhi idinga kuphela ukuzungeza ama-90° kusukela ekuvulekeni ngokuphelele kuya ekuvalekeni ngokuphelele. Ngaphezu kwalokho, ipuleti lebhabhathane levalvu yebhabhathane ngokwayo alinawo amandla okuzikhiya, futhi kudingeka kufakwe umshini wokunciphisa igiya le-worm esiqwini sevalvu. Ngalo, ipuleti lebhabhathane linekhono lokuzikhiya, futhi lingathuthukisa nokusebenza kwevalvu yebhabhathane.
ukuthi siyaqonda izincazelo zama-valve esango nama-valve e-butterfly,vumela's ukwethula umehluko phakathi kwama-valve esango nama-valve e-butterfly:
1. Umehluko ekhonweni lezemidlalo
Encazelweni engenhla, siyaqonda umehluko endleleni kanye nendlela yokuhamba kwamavalvu esango namavalvu ebhabhathane. Ngaphezu kwalokho, amavalvu esango angavulwa ngokuphelele futhi avalwe ngokuphelele, ngakho-ke uma evulwe ngokuphelele, ukumelana nokugeleza kwamavalvu esango kuncane; Amavalvu ebhabhathane Esimweni esivulekile ngokuphelele, ukujiya kwevalvu yebhabhathane kudala ukumelana nendawo egelezayo. Ngaphezu kwalokho, ivalvu yesango inokuphakama okuphezulu kokuvula, ngakho-ke isivinini sokuvula nokuvala sihamba kancane; kuyilapho ivalvu yebhabhathane ingavulwa futhi ivalwe ngokujikeleza okungu-90° kuphela, ngakho isivinini sokuvula nokuvala siyashesha.
2. Umehluko emisebenzini nasekusetshenzisweni kwayo
Amavalvu esango asebenza kahle ekuvaleni, ngakho-ke avame ukusetshenziswa kumapayipi adinga ukuvalwa okuqinile futhi akudingeki avulwe futhi avalwe njalo ukuze kunqunywe indawo ejikelezayo. Ivalvu yesango ayikwazi ukusetshenziswa ukulawula ukugeleza. Ngaphezu kwalokho, ngenxa yokuthi ijubane lokuvula nokuvala kwevalvu yesango lihamba kancane, alifaneleki kumapayipi adinga ukuvalwa okuphuthumayo. Ukusetshenziswa kwamavalvu ebhabhathane kubanzi kakhulu. Amavalvu ebhabhathane awakwazi ukusetshenziswa kuphela ekuvaleni, kodwa futhi anomsebenzi wokulungisa izinga lokugeleza. Ngaphezu kwalokho, ivalvu yebhabhathane iyavula futhi ivale ngokushesha futhi ingavulwa futhi ivalwe njalo. Ifaneleka kakhulu ukusetshenziswa ezimweni ezidinga ukuvulwa noma ukuvalwa okusheshayo.
Amavalvu ebhabhathane mancane ngobukhulu futhi alula ngesisindo kunamavalvu esango, ngakho-ke kwezinye izindawo ezinesikhala esincane sokufakwa, kunconywa ukusebenzisa ivalvu yebhabhathane ye-wafer esonga isikhala kakhulu. Phakathi kwamavalvu amakhulu, amavalvu ebhabhathane yiwona asetshenziswa kakhulu. Amavalvu ebhabhathane nawo anconywa ukuthutha amapayipi emidiya aqukethe ukungcola okuncane.
Ngokuphathelene nokukhethwa kwamavalvu ngaphansi kwezimo eziningi zokusebenza, amavalvu ebhabhathane kancane kancane ashintshe ezinye izinhlobo zamavalvu futhi aba ukukhetha kokuqala kwabasebenzisi abaningi.
3. Umehluko ngentengo
Ngaphansi kwengcindezi efanayo kanye ne-caliber, intengo ye-gate valve iphakeme kuneye-butterfly valve. Kodwa-ke, ububanzi be-butterfly valve bungaba bukhulu kakhulu, futhi intengo ye-butterfly valve enobubanzi obukhulu ayishibhile kune-gate valve.
