Ama-valve esango kanye nama-valve uvemvane ama-valve amabili asetshenziswa kakhulu.Zihluke kakhulu ngokwezakhiwo zazo, izindlela zokuzisebenzisa, kanye nokuvumelana nezimo zokusebenza.Lesi sihloko sizosiza abasebenzisi baqonde kangcono umehluko phakathi kwama-valve esango nama-butterfly valves.Abasebenzisi bosizo olungcono bakhethe ama-valve.
Ngaphambi kokuchaza umehluko phakathi kwe-valve yesango ne-butterfly valve, ake sibheke izincazelo ezifanele zalokhu kokubili.Mhlawumbe ungathola umehluko phakathi kokubili ngokucophelela kusukela encazelweni.
Ivalvu yesango, njengoba negama lisho, inganqamula i-medium epayipini njengesango, futhi iwuhlobo lwevalvu esilusebenzisa sonke ekukhiqizeni nasekuphileni.Ingxenye yokuvula neyokuvala yevalvu yesango ibizwa ngokuthi isango, futhi isango liya phezulu naphansi, futhi isiqondiso salo sokunyakaza sibhekene nesiqondiso sokugeleza kwendawo ephakathi epayipini eliwuketshezi;i-valve yesango i-valve yokusika, engavulwa ngokugcwele noma ivalwe ngokugcwele, futhi ukugeleza akukwazi ukulungiswa.
I-Butterfly valve, eyaziwa nangokuthi i-flap valve.Ingxenye yalo yokuvula neyokuvala iyipuleti levemvane elimise okwediski, eligxilile esiqwini se-valve futhi lizungeza i-axis ye-valve stem ukuze ibone ukuvuleka nokuvala.Isiqondiso sokunyakaza kwe-valve uvemvane iwukuzungezisa endaweni, futhi kudingeka kuphela ukuzungezisa 90° ukusuka ekuvulekeni ngokugcwele kuya kokuvaleka ngokugcwele.Ngaphezu kwalokho, ipuleti uvemvane we-valve uvemvane ngokwalo akanalo ikhono self-locking, futhi isinciphisi igiya izibungu kudingeka ukufakwa esiqwini valve.Ngalo, ipuleti le-butterfly linekhono lokuzikhiya, futhi lingathuthukisa nokusebenza kwe-valve ye-butterfly.
Ukwazi incazelo ye-valve yesango kanye ne-butterfly valve, umehluko phakathi kwe-valve yesango ne-butterfly valve yethulwa ngezansi:
1. Umehluko emandleni okusubatha
Kule ncazelo engenhla, siyawuqonda umehluko endleleni kanye nendlela yokunyakaza kwama-valve esango nama-butterfly valves.Ngaphezu kwalokho, ama-valve esango angavuleka ngokugcwele futhi avalwe ngokugcwele, ngakho-ke lapho evulekile ngokugcwele, ama-valve amasango anokumelana nokugeleza okuncane;ama-butterfly valve Esimweni esivuleke ngokugcwele, ubukhulu be-valve uvemvane budala ukumelana nendawo egelezayo.Ngaphezu kwalokho, i-valve yesango inokuphakama okuphezulu kokuvula, ngakho-ke isivinini sokuvula nokuvala sihamba kancane;kuyilapho i-valve ye-butterfly ingavulwa futhi ivalwe ngokuzungeza i-90 ° kuphela, ngakho-ke isivinini sokuvula nokuvala siyashesha.
2. Umehluko phakathi komsebenzi nokusetshenziswa
Ivalvu yesango inomsebenzi omuhle wokuvala, ngakho-ke isetshenziswa kakhulu kumapayipi adinga ukuvalwa okuqinile futhi ayidingi ukushintshwa ngokuphindaphindiwe ukuze kunqandwe isisetshenziswa esizungezayo.I-valve yesango ayikwazi ukusetshenziselwa ukulungisa izinga lokugeleza.Ngaphezu kwalokho, ngenxa yokuthi isivinini sokuvula nokuvala se-valve yesango sihamba kancane, asifanele ipayipi elidinga ukunqanyulwa ngokushesha.Ukusetshenziswa kwama-butterfly valves kubanzi.Ama-valve e-Butterfly awakwazi ukusetshenziselwa ukusika kuphela, kodwa futhi abe nomsebenzi wokulungisa usayizi wokugeleza.Ngaphezu kwalokho, i-valve ye-butterfly ivula futhi ivaleke ngokushesha, futhi ingavulwa futhi ivalwe njalo, ifaneleka ngokukhethekile ukusetshenziswa ezikhathini ezidinga ukuvulwa noma ukuvala ngokushesha.
Ubukhulu be-valve ye-butterfly buncane kune-valve yesango, futhi isisindo saso sibuye silula kunaleso se-valve yesango.Ngakho-ke, kwezinye izindawo ezinendawo elinganiselwe yokufaka, kunconywa ukusebenzisa i-valve yamavemvane e-wafer esindisa isikhala.Phakathi kwama-valve obubanzi obukhulu, i-valve ye-butterfly isetshenziswa kakhulu, futhi kunconywa ukusebenzisa i-valve ye-butterfly emgqeni ophakathi oqukethe izinhlayiya ezincane zokungcola.
Ekukhetheni ama-valve ezimeni eziningi zokusebenza, ama-butterfly valves kancane kancane ashintsha ezinye izinhlobo zama-valve futhi abe yisinqumo sokuqala sabasebenzisi abaningi.
3. Umehluko ngentengo
Ngaphansi kwengcindezi efanayo kanye nesilinganiso esifanayo, intengo ye-valve yesango iphakeme kunaleyo ye-butterfly valve.Kodwa-ke, izinga le-valve uvemvane lingenziwa libe likhulu kakhulu, futhi intengo ye-valve ye-butterfly enkulu ayishibhile kunaleyo ye-valve yesango.
