Buka Isithombe Esikhulu
Enye yama-valve asetshenziswa kakhulu ohlelweni lwamapayipi.Ilungu lomndeni wekota, ama-butterfly valves ahamba ngokunyakaza okujikelezayo.I-disc ye-valve uvemvane ifakwe esiqwini esijikelezayo.Uma ivuliwe ngokugcwele, i-disc i-engeli engu-90-degree ngokuphathelene ne-actuator yayo.Le valve ifanele ukugeleza okukhulu ngokucindezela okuphansi kanye nemidiya ye-viscous enephesenti elikhulu eliqinile.
Izici ze-valve butterfly zihlanganisa:
– Ukuvula okulula
- Kulula ukufaka
- Kulula ukuyigcina
– Kungabizi ukuyifaka
- Idinga indawo encane
– Izindleko zokunakekela eziphansi
- Ifanele ukusetshenziswa kwama-valve amakhulu
Enye indlela yokuhlukanisa ama-valve ovemvane isekelwe ekwakhiweni kwesihlalo.Omunye umklamo onjalo uwukuba isihlalo esiqinile.Sesikushilo lokho, lesi sihloko sijula ekujuleni kwe-valve uvemvane oluhlezi luqinile.Iphinde ibhekane nomehluko phakathi kwevalve uvemvane ehlezi eyinsimbi kanye nevalve yesihlalo sovemvane esiqinile.
Izinhlobo ze-Butterfly Valves
Njengoba kushiwo ngaphambili, ama-valve ovemvane ahlukaniswa ngezindlela eziningi.Isigaba ngasinye sisebenza kahle ngezinhlelo zokusebenza ezithile.Njengoba kunezindlela ezingaphezu kweyodwa zokuhlukanisa ama-valve, ungenza ngendlela oyifisayo ama-valve ovemvane kuye ngokuthanda kwakho kanye nesicelo sakho.
Amavavu e-Butterfly ngohlobo lokuxhuma
Lokhu kuhlukaniswa kusekelwe endleleni i-valve exhunywe ngayo kumapayipi.
Uhlobo lwe-Wafer
Lona ukonga kakhulu futhi engasindi.Lo mklamo uhlose ukuvimbela ukucindezelwa okuhlukile kwe-bi-directional kanye nokubuyela emuva.Kunama-flange amapayipi amabili ahlanganisa i-valve.Bavala futhi baxhuma i-valve ohlelweni lwamapayipi ngamabholithi.Ukuze uvalwe ngokuqinile, kukhona ama-O-rings nama-gaskets abekwe nhlangothi zombili zevalvu.
Uhlobo lwe-Lug
I-valve yohlobo lwe-butterfly inezigaxa ezibekwe ngaphandle nazungeza umzimba wevalvu.Lezi zivame ukusetshenziswa ezinsizeni eziphelelwe yisikhathi noma ezinhlelweni ezidinga ingcindezi ephansi kuphela.Ama-lugs ahlanganisiwe.Amabhothi, afana nalawo amapayipi, axhuma i-valve epayipini.
I-Butt-Welded
Ivalve uvemvane olushiselwe izinqe inezixhumo ezishiselwe ngqo epayipini.Lolu hlobo lwe-valve lusetshenziselwa ngokuyinhloko izicelo zokucindezela okuphezulu.
I-Flanged
Lolu hlobo lubonakala ngokuba nobuso be-flange nhlangothi zombili.Yilapho ama-valve axhuma khona.Lo mklamo ujwayelekile phakathi kwama-valve amakhulu.
Amavavu e-Butterfly ngohlobo Lokuqondanisa Kwediski
Lolu hlobo lokuhlukaniswa lusekelwe ekwakhiweni kwesihlalo kanye ne-engeli lapho isihlalo sixhunywe kwi-disc.
I-Concentric
Lona umklamo oyisisekelo kakhulu phakathi kwalawo afakwe kulesi sigaba.Lokhu kubizwa nangokuthi ivalve uvemvane ehlezi eqinile noma ngezinye izikhathi idizayini uvemvane oyiziro-offset.Isiqu sidlula phakathi nendawo yediski kanye nesihlalo.Isihlalo sitholakala kububanzi obungaphakathi bomzimba.Isikhathi esiningi, ama-valve ahlezi athambile adinga ukwakheka okugxilile.
I-Double Offset
Lokhu ngezinye izikhathi kubizwa ngokuthi i-double eccentric butterfly valve.I-disc ayihambisani nendawo ephakathi komzimba kanye ne-valve yonke.Lokhu kususa isihlalo ngaphandle kwesigxivizo ngesikhathi sokusebenza.Lo mshini wehlisa umthelela wokungqubuzana kudiski uvemvane.
I-Offset Kathathu
Ivalve yevemvane eyi-triple offset yaziwa nangokuthi i-valve butterfly eccentric kathathu.Indawo yokuhlala idala enye i-offset.Lo mklamo uqinisekisa ukunyakaza okungenantambo kwediski ngesikhathi sokusebenza.Lokhu kuvamile uma izihlalo zenziwe ngensimbi.
Umsebenzi we-Butterfly Valve
Ama-valve ovemvane angenye yalawo mavalvu angasetshenziswa kokubili ukuphusha nokuvala noma ukuvala.Ingakwazi ukulinganisa inani noma ukugeleza kwemidiya edlula kuvalvu lapho kwenziwa umsebenzi othile.Mayelana nendlela yokuvala okuqinile, kufanele ucabangele ubukhulu bomugqa kanye nokwehla kwengcindezi edingekayo lapho i-valve ivuliwe.
Njengoba iyivalvu yokulawula, i-valve uvemvane idinga izibalo ezithile kanye nemvume yezidingo zemidiya kanye nezibalo ezifana nezidingo zokugeleza, ukwehla komfutho, nokunye okuthandwayo.
Indlela Ivaluvu Yevemvane Ehlezi Eqinile Esebenza Ngayo
I-valve uvemvane ehlezi eqinile ibonakala ngesiqu esiboshiwe kudiski futhi sixhunywe phansi kwevalvu.Isikhathi esiningi, izihlalo zalolu hlobo lwevalvu zenziwe ngenjoloba, yingakho, igama elithi ukuqina.
Kanjalo, i-disc incike emandleni okuxhumana aphezulu wesihlalo kanye nesihlalo sokuvala okuqinile.Ngalolu hlobo lomklamo, ukuthintana kwesihlalo kuya-ku-seal kuqala cishe ekujikeni okungu-85-degree.
Amavalvu ovemvane ahlezi eqinile enziwe ngocezu olulodwa.Lokhu kwandisa amandla e-valve kanye nokunciphisa isisindo sayo.Isihlalo se-rubber-back senza kube lula ukusifaka noma ngabe i-valve ye-butterfly ingaphandle.Ngenxa yemvelo yezinto ezibonakalayo, inamandla okuvala uphawu okuthembekile.
Ukuze isihlalo sivale kahle, kufanele silingane futhi sivimbe unqenqema lwediski.Lokhu kwenza i-butterfly valve disc inganyakazi.Lokhu bese kumisa ukugeleza.Enye indlela yokuyibuka i-disc isebenza esihlalweni esitholakala kububanzi obungaphakathi be-valve.
I-Resilient Seat Butterfly Valve Material
Izihlalo zevalve uvemvane zingahlukaniswa zibe ezimbili.Lezi yizinto ezithambile kanye nevalve uvemvane ehlezi ngensimbi.I-valve yesihlalo sovemvane eqinile ingeyokuqala.Isetshenziselwa izinhlelo zokusebenza ezingabalulekile, izihlalo ezinjalo zevemvane zingenziwa ku-EPDM (ethylene propylene diene terpolymer), i-VITON, ne-acrylonitrile-butadiene irabha.
Umehluko phakathi kwamaValuvu Evemvane Ahlezi Ensimbi kanye namaVave Evemvane Ahlezi Eqinile
Amavalvu ovemvane ahlezi eqinile noma lawo agxilile avame ukuhlala ngokuthambile.Uma kuqhathaniswa, i-eccentric noma lezo ezine-offsets, zenziwe ngezihlalo zensimbi, ngaphandle kwe-double offset design.Lokhu kungaba nempahla ehlezi phansi noma insimbi.Ngokungafani nomklamo ophindwe kabili, idizayini yevalvu egxilile ishibhile.
Ukuze kuvalwe kahle, kuhlale kunemvume yezindinganiso zamavalvu ovemvane ahlezi ensimbi.Ngakolunye uhlangothi, kuhlale kunguziro ukuvuza kwevalve uvemvane ehlezi eqinile, ngaphandle uma isihlalo sonakele.
Futhi, ngokuklama kwesihlalo esiqinile, ama-valve ovemvane anjalo athethelela kakhulu imidiya enkulu kakhulu.Kungakhathaliseki ukuthi udoti obanjwe phakathi kwezingxenye ze-valve, isihlalo sisengakwazi ukunikeza ukuqina kophawu.Kulula futhi ukushintsha izihlalo ezihlala ezintofontofo uma kuqhathaniswa nezihlalo zensimbi uma zikhubazekile.Kodwa-ke, ngokwakhiwa kwesihlalo sensimbi, izihlalo zingabhajwa endaweni uma kukhona udoti phakathi kwezingxenye zamavalvu angaphakathi.

Ngokufigqiwe
Amavalvu evemvane ahlezi eqinile athatha amavalvu ebhola ngokuya ngomthamo walo wokuvala.Akukhona nje ukuthi la ma-valve alula ukuwenza, kodwa futhi kushibhile ukuwakhiqiza.Ngokulula kwayo kuhambisana nokulula kokugcina, ukulungisa nokuhlanza.Xhumana nathi ukuze uthole imininingwane eyengeziwe mayelana namavalvu ovemvane we-XHVAL.
