Isebenza Kanjani I-Resilient Seated Butterfly Valve?

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 amabili amapayipi 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 ezinkonzweni eziphelelwe yisikhathi noma ezinhlelweni ezidinga ingcindezi ephansi kuphela.Amalugi acushiwe.Amabhothi, afana nalawo amapayipi, axhuma i-valve epayipini.

I-Butt-Welded

I-valve 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 i-valve uvemvane oluhlezi luqinile 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 ephindwe kathathu yaziwa nangokuthi ivalve uvemvane 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 ukudonsa nokuvala nokuvala.Ingakwazi ukulinganisa inani noma ukugeleza kwemidiya edlula ivalvu 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 nezimfuneko zokugeleza, ukwehla komfutho, nokunye okuthandwayo.

Indlela Ivaluvu Yevemvane Ehlezi Eqinile Esebenza Ngayo

I-valve uvemvane ehlezi eqinile ibonakala ngesiqu esiboshiwe kudiski futhi sinamathiselwe phansi kwevalvu.Isikhathi esiningi, izihlalo zalolu hlobo lwevalvu zenziwe ngerabha, 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 ekuphendukeni okungama-degree angama-85.

Amavalvu ovemvane ahlezi eqinile enziwe ngocezu olulodwa.Lokhu kwandisa amandla e-valve kanye nokunciphisa isisindo sayo.Isihlalo esingemuva kwerabha senza kube lula ukusifaka noma ngabe i-valve uvemvane 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 esiqinile sovemvane ingeyangaphambili.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 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.Ngokuphambene nomklamo ophindwe kabili, idizayini yevalvu egxilile ishibhile.

Ukuze kuvalwe kahle, kukhona njalo ukuvunyelwa okujwayelekile kwamavalvu 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 kumidiya omkhulu 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 ukuyigcina, ukulungisa nokuhlanza.Xhumana nathi ukuze uthole imininingwane eyengeziwe mayelana nama-valve uvemvane we-XHVAL.
