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 lisho, 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 le-butterfly elimise okwediski, elinamathele esiqwini se-valve futhi lijikeleza i-axis ye-valve stem valve ukuze kuvuleke futhi kuvalwe. Isiqondiso sokuhamba kwe-valve ye-butterfly ukuzungeza endaweni, futhi kudingeka kuphela ukuzungeza ama-90° kusukela ekuvulekeni ngokuphelele kuya ekuvalekeni ngokuphelele. Ngaphezu kwalokho, ipuleti le-butterfly le-valve ye-butterfly ngokwayo alinalo ikhono lokuzikhiya, futhi kudingeka kufakwe i-worm gear reducer esiqwini se-valve. Ngalo, ipuleti le-butterfly linekhono lokuzikhiya, futhi lingathuthukisa nokusebenza kwe-valve ye-butterfly.
Njengoba sazi incazelo ye-valve yesango kanye ne-valve ye-butterfly, umehluko phakathi kwe-valve yesango kanye ne-valve ye-butterfly wethulwa ngezansi:
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, amavalvu esango anokumelana okuncane kokugeleza; amavalvu ebhabhathane Esimweni esivulekile ngokuphelele, ukujiya kwevalvu yebhabhathane kudala ukumelana nendawo egelezayo. Ngaphezu kwalokho, ivalvu yesango inokuphakama okuphezulu kokuvula, ngakho isivinini sokuvula nokuvala sihamba kancane; kuyilapho ivalvu yebhabhathane ingavulwa futhi ivalwe ngokujikeleza okungu-90° kuphela, ngakho isivinini sokuvula nokuvala siyashesha.
2. Umehluko phakathi komsebenzi nokusetshenziswa
Ivalvu yesango isebenza kahle ekuvaleni, ngakho-ke isetshenziswa kakhulu kumapayipi adinga ukuvalwa okuqinile futhi akudingeki ukuthi ashintshwe ngokuphindaphindiwe ukuze kunqunywe indawo ejikelezayo. Ivalvu yesango ayikwazi ukusetshenziselwa ukulungisa izinga lokugeleza. Ngaphezu kwalokho, ngenxa yokuthi ijubane lokuvula nokuvala kwevalvu yesango lihamba kancane, ayifanele ipayipi elidinga ukunqunywa ngokushesha. Ukusetshenziswa kwamavalvu ebhabhathane kubanzi kakhulu. Amavalvu ebhabhathane awakwazi ukusetshenziselwa ukusika kuphela, kodwa futhi anomsebenzi wokulungisa usayizi wokugeleza. Ngaphezu kwalokho, ivalvu yebhabhathane iyavula futhi ivale ngokushesha, futhi ingavulwa futhi ivalwe njalo, ikakhulukazi efanele ukusetshenziswa ezimweni ezidinga ukuvulwa noma ukuvalwa ngokushesha.
Usayizi wevalvu yebhabhathane mncane kunevalvu yesango, futhi isisindo sayo silula kunesevalvu yesango. Ngakho-ke, kwezinye izindawo ezinesikhala esincane sokufakwa, kunconywa ukusebenzisa ivalvu yebhabhathane ye-wafer esonga isikhala kakhulu. Phakathi kwamavalvu amakhulu, ivalvu yebhabhathane iyona esetshenziswa kakhulu, futhi kunconywa futhi ukusebenzisa ivalvu yebhabhathane epayipini eliphakathi eliqukethe izinhlayiya ezincane zokungcola.
Ekukhetheni amavalvu ezimweni eziningi zokusebenza, amavalvu ebhabhathane ashintshe kancane kancane ezinye izinhlobo zamavalvu futhi aba ukukhetha kokuqala kwabasebenzisi abaningi.
3. Umehluko ngentengo
Ngaphansi kwengcindezi efanayo kanye ne-caliber efanayo, intengo ye-valve yesango iphakeme kuneye-valve ye-butterfly. Kodwa-ke, i-caliber ye-valve ye-butterfly ingenziwa ibe nkulu kakhulu, futhi intengo ye-valve ye-butterfly ye-caliber enkulu ayishibhile kune-valve yesango.
