Ingabe ama-butterfly valves ahamba kabili?

I-Butterfly Valve iwuhlobo lwedivayisi yokulawula ukugeleza ene-quarter-turn rotational motion , 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 i-Concentric yazi njengamavalvu ovemvane ahlala phansi noma ayi-zero-offset , Izingxenye zawo zihlanganisa :I-valve yomzimba , idiski , isihlalo , isiqu kanye ne-seal .isakhiwo se-valve uvemvane ogxilile yidiski futhi isihlalo siqondaniswe maphakathi nevalvu , futhi i-shaft 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 ku-stem edlula emzimbeni we-valve, futhi ukuguqula i-stem ijikeleza i-disk noma ukuvula noma ukuvala i-valve, Njengoba i-shaft ijikeleza, i-disc ivula indawo evulekile noma evulekile kancane, ivumela uketshezi ukuba lugeleze ngokukhululekile .Esikhundleni esivaliwe, i-Shaft ijikeleza 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 kalula, ukufakwa nokugcinwa nokugcinwa, i-valve ye-butterfly elula yenza kube lula futhi isheshe ukuyifaka, inganciphisa izindleko zabasebenzi, Umklamo wezomnotho olula ngokwemvelo oqukethe izingxenye ezimbalwa ezihambayo, ngakho-ke izindawo zokugqoka ezimbalwa, zinciphisa kakhulu izidingo zabo zokunakekelwa.
3 Idizayini engasindi futhi ehlangene kanye nobukhulu obuncane bobuso nobuso bevalvu yevemvane egxilile, Ivumela ukufakwa futhi isetshenziswe ezindaweni ezinomkhawulo womkhathi, Idinga isikhala esincane uma iqhathaniswa nezinye izinhlobo zamavalvu, njengesango noma amavalvu embulunga, futhi ukubumbana kwawo kwenza kokubili ukufakwa nokusebenza kube lula, 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 .
