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 yesangoluhlobo lwe-valve 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 yokunyakaza 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. Ukwengeza, ngenxa yokuthi isivinini sokuvula nokuvala i-valve yesango ihamba kancane, ayifaneleki amapayipi okudingeka anqunywe 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 nokulinganisa, 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.
