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

I-valve yesangofuthiuvemvane valveama-valve amabili asetshenziswa kakhulu.Zombili zihluke kakhulu ngokwesakhiwo sazo nokusebenzisa izindlela, ukuzivumelanisa nezimo zokusebenza, njll. Lesi sihloko sizosiza abasebenzisi baqonde umehluko phakathiama-valve esangofuthiizivalo uvemvanengokujulile, ukuze usize kangcono abasebenzisi ukukhetha ama-valve.
Ngaphambi kokuchaza umehluko phakathii-valve yesangokanye butterfly valve, ake sibheke izincazelo ezimbili.Mhlawumbe kusukela encazelweni, ungathola ngokucophelela umehluko.
Ama-valve esango, njengoba negama lisho, inganqamula i-medium epayipini njengesango, okuwuhlobo lwe-valve esizoyisebenzisa ekukhiqizeni nasekuphileni.Ingxenye yokuvula neyokuvala yei-valve yesangoibizwa ngokuthi ipuleti lesango.Ipuleti lesango lisetshenziselwa ukuphakamisa ukunyakaza, futhi isiqondiso salo sokunyakaza sibhekene nesiqondiso sokugeleza kwendawo ephakathi epayipini eliwuketshezi.Ii-valve yesangoiwuhlobo lwevalvu yokunqamula, engavulwa noma ivalwe kuphela, futhi izinga lokugeleza alikwazi ukulungiswa.

Butterfly valve, njengoba yaziwa ngokuthi i-flip valve.Ingxenye yayo evulayo nevalayo iyipuleti levemvane elimise okwe-disc, eligxilile esiqwini futhi lizungeza i-stem shaft ukuze livuleke futhi livale.Isiqondiso sokunyakaza kwe-uvemvane valveizungeziswa lapho ikhona futhi ithatha kuphela u-90° ukuzungezisa ukusuka ekuvulekeni okugcwele kuya ekuvaleni okugcwele.Ngaphezu kwalokho, ipuleti uvemvane we valve uvemvane ayinalo ikhono self-ukuvala.Isinciphisi se-turbine sidinga ukufakwa esiqwini.Ngalo, i-valve ye-butterfly inekhono lokuzikhiya, futhi ngesikhathi esifanayo, ingaphinde ithuthukise ukusebenza kwe-valve butterfly.

Ngemva kokuqonda incazelo yei-valve yesangokanye butterfly valve, umehluko phakathii-valve yesangokanye ne-butterfly valve yethulwa ngezansi:

1. Umehluko emandleni emoto

Ngokuya ngencazelo engaphezulu, siyawuqonda umehluko phakathi kwesiqondiso nendlela yokuhamba kwe-i-valve yesangokanye nevalve uvemvane.Ngaphezu kwalokho, ngenxa yokuthi i-valve yesango ingavulwa ngokugcwele futhi ivalwe kuphela, ukumelana nokugeleza kwe-valve yesango kuncane uma ivuliwe ngokugcwele;ngenkathi iuvemvane valveivuliwe ngokugcwele, futhi ukushuba kweuvemvane valveinokumelana ne-circulation medium.Ngaphezu kwalokho, ukuphakama kokuvula kwe-i-valve yesangoiphakeme kakhulu, ngakho-ke isivinini sokuvula nokuvala sihamba kancane;ngenkathi iuvemvane valveidinga kuphela ukuzungezisa u-90° ukuze kuzuzwe ukuvula nokuvala, ngakho ukuvula nokuvala kuyashesha.

2. Umehluko ezindimeni nasekusetshenzisweni

Ukusebenza kokuvala i-valve yesango kuhle, ngakho-ke isetshenziswa kakhulu kumapayipi adinga ukubekwa uphawu okuqinile futhi akudingi ukushintshwa ngokuphindaphindiwe ukuze kunqunywe imidiya yokujikeleza.I-valve yesango ayikwazi ukusetshenziselwa ukulawula ukugeleza.Ngaphezu kwalokho, ngenxa yokuthi isivinini sokuvula nokuvala i-valve yesango ihamba kancane, ayifaneleki amapayipi adinga ukunqunywa ngokushesha.I-valve ye-butterfly isetshenziswa kakhulu.I-valve ye-butterfly ayikwazi ukuncishiswa kuphela, kodwa futhi inomsebenzi wokulungisa ukugeleza.Ngaphezu kwalokho, i-valve ye-butterfly ivula futhi ivale ngokushesha, futhi ingavula futhi ivale njalo, ikakhulukazi efanelekile ukusetshenziswa ezimweni lapho ukuvulwa okusheshayo noma ukusika kuyadingeka.

Umumo nesisindo se-valve uvemvane kuncane kune-valve yesango, ngakho-ke kwezinye izindawo ezinendawo elinganiselwe yokufaka, kunconywa ukusebenzisa i-valve yesiqeshana sovemvane esonga isikhala.Amavalve ovemvane yiwona asetshenziswa kakhulu kumavalvu anezinga elikhulu, futhi amavalve ovemvane nawo ayanconywa kumapayipi aphakathi nendawo aqukethe ukungcola nezinhlayiya ezincane.

Ekukhetheni ama-valve ezimeni eziningi zokusebenza, ama-butterfly valves kancane kancane ashintsha ezinye izinhlobo zama-valve futhi abe yisinqumo sokuqala kubasebenzisi abaningi.

3. Umehluko ngentengo

Ngaphansi kokucindezela okufanayo kanye nesilinganiso, intengo ye-valve yesango iphakeme kunaleyo ye-butterfly valve.Kodwa-ke, izinga le-valve butterfly lingaba likhulu kakhulu, futhi intengo yezinga elikhuluuvemvane valveayishibhile kune-valve yesango.
