I-valve yokuhlola i-Butterflyibhekisela ku-valve evula ngokuzenzakalelayo futhi ivale i-disc kuye ngokugeleza kwe-medium ngokwayo, futhi isetshenziselwa ukuvimbela okuphakathi ukuthi kungagelezi emuva.Ibizwa nangokuthi i-valve yokuhlola, i-valve yendlela eyodwa, i-valve yokugeleza ehlehlayo, kanye ne-back pressure valve.I-valve yokuhlola iwuhlobo lwe-valve othomathikhi, umsebenzi wayo oyinhloko ukuvimbela ukugeleza kwangemuva kwe-medium, ukuvimbela ipompo kanye ne-motor motor ukuthi ingahlehli, kanye nokukhishwa kwe-container medium.Amavalvu okuhlola angasetshenziswa futhi ukunikeza amapayipi amasistimu asizayo lapho ukucindezela kungase kukhuphuke ngaphezu kokucindezela kwesistimu.Amavalvu okuhlola angahlukaniswa abe amavalvu okuhlola ukujika (azungezayo ngokuya phakathi nendawo amandla adonsela phansi), phakamisa amavalvu okuhlola (ahamba eksisi), namavalvu okuhlola uvemvane (azungeza phakathi nendawo).
Umsebenzi
Umsebenzi we-valve yokuhlola uvemvane ukuvumela kuphela okuphakathi ukuthi kugeleze ohlangothini olulodwa futhi kuvimbele ukugeleza ohlangothini olulodwa.Ngokuvamile lolu hlobo lwe-valve lusebenza ngokuzenzakalelayo.Ngaphansi kwesenzo somfutho we-fluid ogeleza ohlangothini olulodwa, i-valve flap iyavuleka;lapho uketshezi lugeleza ngakolunye uhlangothi, ukucindezela koketshezi kanye nokuziqondanisa kwe-valve flap kusebenza esihlalweni se-valve, ngaleyo ndlela kunqamule ukugeleza.
Izici zesakhiwo
Ama-valve okuhlola uvemvane ahlanganisa ama-valve okuhlola ama-swing nama-valve okuhlola okuphakamisa.I-valve yokuhlola i-swing ine-hinge mechanism kanye ne-valve disc njengomnyango ohlezi ngokukhululekile endaweni yesihlalo se-valve ethambekele.Ukuze uqinisekise ukuthi i-valve clack ingafinyelela endaweni efanele yesihlalo se-valve ngaso sonke isikhathi, i-valve clack yakhelwe ngendlela yamahinge ukuze i-valve clack ibe nesikhala esanele sokuphenduka futhi yenze i-valve clack ngempela futhi ixhumane isihlalo se-valve.I-valve clack ingenziwa ngensimbi, isikhumba, irabha, noma isembozo sokwenziwa singafakwa ensimbi, kuye ngezidingo zokusebenza.Lapho i-valve yokuhlola i-swing ivuliwe ngokugcwele, umfutho we-fluid cishe awuphazamiseki, ngakho-ke ukwehla kwengcindezi nge-valve kuncane kakhulu.I-valve disc ye-valve yokuhlola i-lift ihlezi endaweni yokuvala yesihlalo se-valve emzimbeni we-valve.Ngaphandle kokuthi i-disc ingaphakanyiswa futhi yehliswe ngokukhululekile, yonke i-valve ifana ne-valve yokuvala.Umfutho we-fluid uphakamisa i-disc endaweni yokuvala isihlalo, futhi ukugeleza kwe-backflow ye-medium kubangela ukuthi i-disc ibuyele esihlalweni futhi inqamule ukugeleza.Ngokwemibandela yokusetshenziswa, i-valve clack ingaba isakhiwo sensimbi yonke, noma ingaba sesimweni sephedi yerabha noma indandatho yerabha efakwe kuhlaka lwe-valve clack.Njenge-valve yokuvala, ukudlula koketshezi nge-valve yokuhlola i-lift nakho kuncane, ngakho-ke ukwehla kwengcindezi nge-valve yokuhlola i-lift kukhulu kunaleyo ye-valve yokuhlola i-swing, futhi izinga lokugeleza kwe-valve yokuhlola i-swing ivinjelwe. kuyaqabukela.Lolu hlobo lwe-valve ngokuvamile kufanele lufakwe ngokuvundlile epayipini.
Ngokwesakhiwo sayo nendlela yokufaka, i-valve yokuhlola ingahlukaniswa ibe:
1. I-disc yevalve yokuhlola uvemvane imise okwe-disc, futhi izungeza i-shaft yesihlalo se-valve.Ngenxa yokuthi umzila wangaphakathi we-valve ulula, ukumelana nokugeleza kuncane kunokwe-valve yokuhlola uvemvane.Ifanele ukugeleza okuphansi nokugeleza okungabuyi.Izikhathi ezinkulu ezinobubanzi obunoshintsho oluvamile, kodwa azifaneleki ukugeleza kwe-pulsating, nokusebenza kwayo kokuvala akulungile njengohlobo lokuphakamisa.I-valve yokuhlola uvemvane ihlukaniswe yaba izinhlobo ezintathu: i-valve eyodwa, i-valve ephindwe kabili kanye ne-valve eminingi.Lezi zinhlobo ezintathu zihlukaniswa ngokuyinhloko ngokobubanzi be-valve.Inhloso ukuvimbela i-medium ukuthi ingami noma igeleze ihlehle futhi yenze buthaka ukushaqeka kwe-hydraulic.
2. I-valve yokuhlola i-Butterfly: Ngokwendlela yokusebenza ye-disc, ihlukaniswe yaba izinhlobo ezimbili: 1. I-valve yokuhlola ene-disc eshelelayo eduze komugqa ophakathi oqondile womzimba we-valve.Ivalve yokuhlola uvemvane ingafakwa kuphela epayipini elivundlile.Ibhola eliyindilinga lingasetshenziswa kudiski yevalvu yokuhlola enobubanzi obuncane.Umumo womzimba we-valve we-valve yokuhlola uvemvane uyafana ne-valve yembulunga (engasetshenziswa ngokufana ne-globe valve), ngakho-ke i-coefficient yayo yokumelana noketshezi inkulu kakhulu.Ukwakheka kwayo kufana ne-valve yokumisa, futhi umzimba we-valve ne-disc kuyafana ne-valve yokumisa.Ingxenye engenhla yediski ye-valve kanye nengxenye engezansi yesembozo se-valve icutshungulwa ngemikhono eqondisayo.Umhlahlandlela wediski ungahanjiswa phezulu naphansi ngokukhululekile kumkhono womhlahlandlela wevalvu.Lapho i-medium igeleza yehla nomfula, i-disc ivuleka ngokuphonswa kwe-medium.Yehlela phansi esihlalweni sevalvu ukuvimbela i-medium ukuthi ingabuyeli emuva.Isiqondiso se-medium inlet kanye nemigudu yokuphuma ye-valve yokuhlola i-butterfly eqondile ibhekene nesiqondiso sesiteshi sesihlalo se-valve;i-valve yokuhlola i-vertical lift inesiqondiso esifanayo se-medium inlet kanye neziteshi zokuphuma njengesiteshi sesihlalo se-valve, futhi ukumelana nokugeleza kwayo kuncane kunohlobo oluqondile;2. Ivalvu yokuhlola lapho idiski izungeza khona iphinikhodi esihlalweni.Ivalvu yokuhlola uvemvane inesakhiwo esilula futhi ingafakwa kuphela epayipini elivundlile, elingasebenzi kahle ngokuvala.
3. I-valve yokuhlola emgqeni: ivalvu idiski yayo eshelelayo eduze komugqa omaphakathi womzimba wevalvu.I-valve yokuhlola emgqeni iwuhlobo olusha lwevalvu.Incane ngosayizi, ilula ngesisindo, futhi inhle ekucubunguleni ubuchwepheshe.Ingenye yezinkomba zokuthuthukiswa kwama-valve okuhlola.Kodwa i-coefficient yokumelana noketshezi inkulu kancane kune-valve yokuhlola i-swing.
4. Ivalvu yokuhlola ukucindezela: Le valve isetshenziswa njengamanzi okuphakela kubhayela kanye nevalve yokuvala isitimu.Inomsebenzi obanzi we-valve yokuhlola i-lift kanye ne-valve yokumisa noma i-engeli valve.
Ngaphezu kwalokho, kukhona ama-valve okuhlola angafaneleki ukufakwa kwe-pump outlet, njengama-valve onyawo, ukulayishwa kwentwasahlobo, uhlobo lwe-Y namanye ama-valve okuhlola.
Izici zokusebenzisa nokusebenza:
Le valve isetshenziswa njengethuluzi lokuvimbela ukubuyela emuva kwe-medium kumapayipi ezimboni.
Ukufakwa kusemqoka
Ukufakwa kwe-valve yokuhlola kufanele kunake izinto ezilandelayo:
1. Ungavumeli i-valve yokuhlola ukuthi ithwale isisindo epayipini.Ama-valve okuhlola amakhulu kufanele asekelwe ngokuzimela ukuze angathinteki ukucindezela okukhiqizwa uhlelo lwamapayipi.
2. Uma ufaka, qaphela isiqondiso sokugeleza okuphakathi kufanele kuhambisane nesiqondiso somcibisholo ovotelwe umzimba we-valve.
3. Ivalvu yokuhlola i-flap ephakamayo kufanele ifakwe epayipini elime mpo.
4. Ivalvu yokuhlola i-flap evundlile yohlobo lokuphakamisa kufanele ifakwe epayipini elivundlile.
1. Isimiso somsebenzi nencazelo yesakhiwo:
Ngesikhathi sokusebenzisa le valve, i-medium igeleza iqonde kumcibisholo oboniswe esithombeni.
2. Uma i-medium igeleza ngendlela ecacisiwe, i-valve flap ivulwa ngamandla we-medium;lapho okuphakathi kugeleza emuva, indawo yokuvala ye-valve flap kanye nesihlalo se-valve sivalwe ngenxa yesisindo se-flap ye-valve kanye nesenzo samandla abuyela emuva we-medium.Valani ndawonye ukuze kuzuzwe inhloso yokuvimbela i-medium ukuthi ingagelezi ihlehle.
3. Indawo evalekayo yomzimba we-valve kanye ne-valve clack isebenzisa insimbi engagqwali eshisela ngaphezulu.
4. Ubude besakhiwo sale valve buhambisana ne-GB12221-1989, futhi usayizi wokuxhuma kwe-flange uhambisana ne-JB/T79-1994.
Isitoreji, Ukufakwa kanye Ukusebenzisa
5.1 Zombili iziphetho zephaseji lamavalvu kumele zivalwe, futhi kube negumbi elomile nelingena umoya.Uma igcinwe isikhathi eside, kufanele ihlolwe njalo ukuze igweme ukugqwala.
I-5.2 I-valve kufanele ihlanzwe ngaphambi kokufakwa, futhi amaphutha abangelwa ngesikhathi sokuthutha kufanele asuswe.
5.3 Ngesikhathi sokufakwa, kufanele uhlole ngokucophelela ukuthi izimpawu nama-nameplates kuvalvu ziyahlangabezana yini nezidingo zokusetshenziswa.
5.4 Ivalvu ifakwe epayipini elivundlile futhi ikhava yevalvu ibheke phezulu.
9. Ukwehluleka okungenzeka, Izimbangela kanye nezindlela zokuqeda:
1. Ukuvuza lapho kuhlangana khona i-valve yomzimba nebhonethi:
(1) Uma i-nati ingaqiniswa noma ikhululiwe ngokulinganayo, ingashintshwa kabusha.
(2) Uma kunomonakalo noma ukungcola endaweni yokuvala i-flange, indawo yokuvala kufanele incishwe noma kususwe ukungcola.
(3) Uma i-gasket yonakalisiwe, kufanele ishintshwe entsha.
2. Ukuvuza endaweni yokuvala ye-valve clack kanye nesihlalo sevalvu
(1) Kukhona ukungcola phakathi kwezindawo zokuvala, ezingahlanzwa.
(2) Uma indawo yokuvala ilimele, gaya kabusha noma uphinde uvele futhi ucutshungulwe.
