Ingabe ama-butterfly valves ahamba kabili?

I-Butterfly Valve iwuhlobo lwedivayisi yokulawula ukugeleza enokunyakaza kwe-quarter-turn rotational , Isetshenziselwa amapayipi ukulawula noma ukuhlukanisa ukugeleza koketshezi ( uketshezi noma amagesi ) , Nokho, Ivalve yevemvane yekhwalithi enhle nokusebenza kufanele ifakwe uphawu oluhle. . Ingabe ama-butterfly valves ahamba kabili? Ngokuvamile sihlukanisa i-valve uvemvane sibe ama-valve uvemvane a-Concentric kanye ne-eccentric butterfly valve .
Sizoxoxa mayelana ne-concentric butterfly valve bidirectional njengoba ngezansi:

Iyini i-valve yevemvane eyi-Concentric?

I-valve uvemvane olugxilile yazi njengamavalvu ovemvane ahlala phansi noma ayi-zero-offset , Izingxenye zawo zihlanganisa :I-valve body , idiski , isihlalo , isiqu kanye ne-seal .isakhiwo se-valve uvemvane ogxilile yidiski futhi isihlalo siqondaniswe maphakathi nevalvu , futhi umphini noma isiqu sitholakala phakathi nediski . Lokhu kusho ukuthi i-disc izungeza ngaphakathi kwesihlalo esithambile , Izinto zokuhlala zingafaka i-EPDM , i-NBR Viton Silicon Teflon Hypalon noma i-elastomer.

Indlela yokusebenzisa i-valve ye-butterfly egxilile?

Ukwakhiwa kwevalve uvemvane kulula uma kuqhathaniswa , kunezindlela ezintathu zokusebenzisa i-actuator yokusebenza :I-Lever Handle yosayizi omncane , Ibhokisi le-Worm Gear lamavalvu Amakhulu ukuze kube lula ukulawula nokusebenza Okuzenzakalelayo ( zifaka Izicupha Kagesi Nezomoya )
I-valve uvemvane isebenza ngokuzungezisa idiski (noma i-vane) ngaphakathi kwepayipi ukulawula ukugeleza koketshezi. I-disk ifakwe esiqwini esidlula emzimbeni we-valve, futhi ukuguqula i-stem kuzungezisa idiski ukuze ivule noma ivale i-valve, Njengoba i-shaft ijikeleza, i-disc ivula indawo evulekile noma evulekile kancane, ivumela uketshezi ukuthi lugeleze ngokukhululekile . Esimeni esivaliwe, i-Shaft izungezisa i-disc ukuze ivimbele ukugeleza ngokuphelele futhi ivale i-valve.

Ingabe ama-butterfly valves ahamba kabili?

I-Bidirectional -izindlela zingakwazi ukulawula ukugeleza kuzo zombili izinkomba ,Njengoba sikhulume , isimiso sokusebenza kwamavalvu singafinyelela izimfuneko .Ngakho ama-valve ovemvane agxilile ahamba kabili , Kunezinzuzo eziningi zokusebenzisa i-valve butterfly egxilile.
1 Iyonga kakhulu kunezinye izinhlobo zamavalvu ngenxa yokwakheka kwayo okulula nezinto ezimbalwa ezidingekayo ekwakheni. Ukonga izindleko kutholakala ikakhulukazi kumasayizi amavalvu amakhulu.
2 Ukusebenza okulula, ukufakwa nokugcinwa nokugcinwa, i-valve butterfly elula yenza kube lula futhi isheshe ukuyifaka, inganciphisa izindleko zabasebenzi, idizayini elula, engokomnotho equkethe izingxenye ezimbalwa ezihambayo, futhi ngenxa yalokho amaphuzu ambalwa okugqoka, anciphisa kakhulu ukulungiswa kwawo. izidingo.
3 Idizayini engasindi futhi ehlangene kanye nobukhulu obuncane bobuso nobuso bevalvevemvane egxilile, Ivumela ukufakwa futhi isetshenziswe endaweni elinganiselwe, idinga isikhala esincane uma iqhathaniswa nezinye izinhlobo zamavalvu, njengesango noma amavalvu embulunga, futhi ukubumbana kwawo kwenza kube lula. kokubili ukufakwa nokusebenza , ikakhulukazi kumasistimu agcwele phama .
4 Ukwenza ngokushesha, umklamo ojikelezayo we-engeli engakwesokudla (90-degree) uhlinzeka ngokuvula nokuvala ngokushesha. Lesi sici sibalulekile ezinhlelweni zokusebenza lapho impendulo esheshayo ibalulekile, njengamasistimu okuvala ucingo oluphuthumayo noma izinqubo ezinezidingo zokulawula ezinembile. Ikhono lokuvula nokuvala ngokushesha lithuthukisa ukuphendula kwesistimu, okwenza ama-valve ovemvane agxile kakhulu afaneleke kakhulu ukulawula ukugeleza nokulawula kokuvula/ukuvala kumasistimu afuna isikhathi sokusabela esiphezulu.

Ekugcineni, i-valve uvemvane ezinhlangothi zombili enezici zombili zokuvala ingenxa yesakhiwo sayo esinwebekayo sokuvala phakathi kwesihlalo se-valve nediski uvemvane, Ukuqinisekisa ukuvala okungaguquguquki kungakhathaliseki ukuthi uketshezi luya ngakuphi .Lo mklamo uthuthukisa ukusebenza nokuthembeka kwevalvu ohlelweni lokulawula uketshezi oluphindwe kabili .
