Uyini umehluko phakathi kwe-Butterfly Valve ne-Gate Valve?

I-valve yesangofuthiivalvu yebhabhathaneama-valve amabili asetshenziswa kakhulu. Womabili ahluke kakhulu ngokwesakhiwo sawo kanye nezindlela zawo zokusebenzisa, ukuzivumelanisa nezimo zokusebenza, njll. Lesi sihloko sizosiza abasebenzisi ukuqonda umehluko phakathiamavalvu esangofuthiamavalvu ebhabhathanengokujulile, ukuze kusizwe kangcono abasebenzisi ukuthi bakhethe ama-valve.
Ngaphambi kokuchaza umehluko phakathiivalvu yesangokanye ne-butterfly valve, ake sibheke izincazelo zalezi ezimbili. Mhlawumbe kusukela encazelweni, ungathola umehluko ngokucophelela.
Amavalvu esango, njengoba igama lisho, ingasika indlela esetshenziswayo epayipini njengesango, okuwuhlobo lwevalvu esizoyisebenzisa ekukhiqizeni nasekuphileni. Ingxenye yokuvula nokuvala yeivalvu yesangoibizwa ngokuthi ipuleti lesango. Ipuleti lesango lisetshenziselwa ukuphakamisa ukunyakaza, futhi isiqondiso salo sokunyakaza siqonde ngqo esiqondisweni sokugeleza kwe-medium epayipini loketshezi.ivalvu yesangouhlobo lwevalvu yokunqunywa, engavulwa noma ivalwe ngokuphelele kuphela, futhi izinga lokugeleza alikwazi ukulungiswa.

I-valve yebhabhathane, eyaziwa ngokuthi i-flip valve. Ingxenye yayo yokuvula nokuvala iyipuleti lebhabhathane elimise okwediski, elinamathele esiqwini futhi lijikeleza umgodi wesiqu ukuze livuleke futhi livale. Isiqondiso sokunyakaza kwe-ivalvu yebhabhathaneijikeleziswa lapho ikhona futhi ithatha kuphela ukujikeleza okungu-90° kusukela ekuvulekeni okugcwele kuya ekuvalekeni okugcwele. Ngaphezu kwalokho, ipuleti levemvane levelu yevelu yevelu ngokwayo alinawo amandla okuzivala. I-turbine reducer idinga ukufakwa esiqwini. Ngayo, ivelu yevelu yevelu inekhono lokuzikhiya, futhi ngesikhathi esifanayo, ingathuthukisa nokusebenza kwevelu yevelu yevelu.

Ngemva kokuqonda incazelo ye-ivalvu yesangokanye ne-butterfly valve, umehluko phakathiivalvu yesangokanye ne-butterfly valve yethulwa ngezansi:

1. Umehluko ekhonweni lokunyakaza

Ngokuphathelene nencazelo yobuso, siyaqonda umehluko phakathi kwesiqondiso nendlela yokunyakaza kwe-ivalvu yesangokanye nevalvu yebhabhathane. Ngaphezu kwalokho, ngenxa yokuthi ivalvu yesango ingavulwa futhi ivalwe ngokuphelele kuphela, ukumelana kokugeleza kwevalvu yesango kuncane uma ivulwe ngokuphelele; kuyilaphoivalvu yebhabhathaneivulekile ngokuphelele, futhi ubukhulu be-ivalvu yebhabhathaneinokumelana ne-circulation medium. Ngaphezu kwalokho, ukuphakama kokuvula kwe-ivalvu yesangokuphakeme kakhulu, ngakho-ke isivinini sokuvula nokuvala sihamba kancane; kuyilaphoivalvu yebhabhathaneidinga ukuzungeza ama-90° kuphela ukuze kuvulwe futhi kuvalwe, ukuze kuvulwe futhi kuvalwe ngokushesha.

2. Umehluko ngezindima kanye nokusetshenziswa kwazo

Ukusebenza kokuvala kwevalvu yesango kuhle, ngakho-ke isetshenziswa kakhulu kumapayipi adinga ukuvalwa okuqinile futhi angadingi ukushintshwa ngokuphindaphindiwe ukuze kunqunywe imidiya yokujikeleza kwegazi. Ivalvu yesango ayikwazi ukusetshenziswa ukulawula ukugeleza kwegazi. Ngaphezu kwalokho, ngenxa yokuthi ijubane lokuvula nokuvala kwevalvu yesango lihamba kancane, ayifanele amapayipi adinga ukususwa ngokushesha. Ivalvu yebhabhathane isetshenziswa kabanzi. Ivalvu yebhabhathane ayikwazi ukunqunywa kuphela, kodwa futhi inomsebenzi wokulungisa ukugeleza kwegazi. Ngaphezu kwalokho, ivalvu yebhabhathane iyavula futhi ivale ngokushesha, futhi ingavula futhi ivale njalo, ikakhulukazi efanele ukusetshenziswa ezimweni lapho kudingeka khona ukuvulwa noma ukusika okusheshayo.

Ukuma nesisindo sevalvu yevemvane kuncane kunesevalvu yesango, ngakho-ke kwezinye izindawo ezinesikhala esincane sokufaka, kunconywa ukusebenzisa ivalvu yevemvane egcina isikhala kakhulu. Amavalvu evemvane yiwona asetshenziswa kakhulu kumavalvu amakhulu, kanti amavalvu evemvane nawo anconywa emapayipini aphakathi aqukethe ukungcola nezinhlayiya ezincane.

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-calibre, intengo ye-valve yesango iphakeme kuneye-valve ye-butterfly. Kodwa-ke, i-calibre ye-valve ye-butterfly ingaba nkulu kakhulu, futhi intengo ye-calibre enkuluivalvu yebhabhathaneakushibhile kune-valve yesango.
