Emavalvu elisangofutsiemavalvu evivanetisetjentiswa njengekushintja kulawula lizinga lekugeleza ekusetjentisweni kwemaphayiphi. Kuliciniso, kusenetindlela enchubeni yekukhetsa emavalvu e-butterfly kanye nemavalvu esango.
Kunethiwekhi yephayiphi yekuniketa emanti, kute kuncishiswe kujula kwekumbonya umhlabatsi wemaphayiphi, ububanti jikelele beliphayiphi lelikhulu ifakwe i-valve ye-butterfly, futsi uma kujula kwekumbonya umhlabatsi akubalulekile, zama kukhetsa i-valve yesango, kepha intsengo ye-valve yesango yekucaciswa lokufanako kwe-butter iphakeme kune-pri. Njengobe kunjalo ngemugca wekubeka umkhawulo we-caliber, indzawo ngayinye kufanele icatjangwe ngekuya ngesimo ngasinye. Kusukela kumbono wekusetjentiswa kweminyaka lelishumi leyengcile, kwehluleka kwe-valve ye-butterfly kuphakeme kunaleyo ye-Ivalvu yesango, ngako kufanelekile kunaka kwandzisa libanga lekusetjentiswa kwevalve yesango uma timo tivumela.
Eminyakeni yamuva, bakhiciti labaningi bemavalvu asekhaya batfutfukise futsi balingisa emavalvu esango le-soft seal, lanetimphawu letilandzelako kune-wedge yendabuko noma emavalvu e-parallel double gate:
Iivalvuumtimba kanye nebhonethi yevalve yesango lekuvala lethambile kulahlwa ngendlela yekulahla lokunembile, leyakhiwa ngesikhatsi sinye, ngekuyinhloko hhayi ngemshini, futsi ayisebentisi tindandatho telitfusi tekuvala, kugcina tinsimbi letingekho insimbi.
Kute umgodzi phansi kwe .Ivalvu yesango lekuvala lethambile, kute kugcwala kwe-slag, kanye nelizinga lekuhluleka kwe- .Ivalvu yesangokuvulwa nekuvalwa kuphansi.
Ipuleti levalve lelayiniwe ngeluphawu lolutsambile liyafana ngebukhulu futsi liyashintjana kakhulu.
Ngako-ke, i-valve yesango le-soft seal itawuba lifomu lemboni yekuniketa emanti lejabulela kulitsatsa. Kwanyalo, bubanti be valve ye soft seal gate lekhicitwa eChina ngu 1500mm, kepha bubanti bebakhiciti labaningi busemkhatsini wa 80-300mm, futsi kusenetinkinga letinyenti enchubeni yekukhicita yasekhaya. Incenye lebalulekile ye-valve yesango le-soft seal yi-valve plate lefakwe iraba, futsi tidzingo tebuchwepheshe te-valve plate lefakwe iraba tiphakeme, futsi akusibo bonkhe bakhiciti bemave angaphandle labangakhona kuyifeza, futsi ivame kutsengwa futsi ihlanganiswe efemini ngelizinga lelitsembekile.
Ibhulokhi yemantongomane elitfusi yesivalo lesitsambile sasekhayaIvalvu yesangoifakwe futsi ilengiswe ngetulu kwelipuleti levalve lelinelucwencwe lwerabha, lefana nesakhiwo sevalve yesango, futsi lelucwencwe lwerabha lwelipuleti levalve kulula kulihlubula ngenca yekukhuhlana lokusebenta kwebhulokhi lemantongomane. Ku-valve yesango le-soft seal yenkampani yangaphandle, le-copper nut block ifakwe kule-ram lefakwe irabha kute yakhe yonkhe, lekuncoba lokushiyeka lokungenhla, kepha i-concentricity yenhlanganisela ye-valve cover kanye nemtimba we-valve iphakeme.
Nomakunjalo, uma uvula nekuvala ivalve yesango lekuvala lelitsambile, akukafaneli ivalwe kakhulu, uma nje umphumela wekumisa emanti ufinyelelwa, ngaphandle kwaloko akusiko melula kuvula noma kucasula luhlangotsi lwerabha. Umkhiciti wevalve, ekuhlolweni kwemfutfo wevalve, kusetjentiswa kwe torque wrench kulawula lizinga lekuvala, njengenkampani yemanti labasebentisa emavalvu kumele nabo balandzele lendlela yekuvula nekuvala.
Yini umehluko emkhatsini wekusebentisa .emavalvu evivanefutsiemavalvu esango?
Ngekuya kwemsebenti kanye nekusetjentiswa kwevalve yesango kanye nevalve yebutterfly, kugeleta kwekumelana kwevalve yesango kuncane, kusebenta kwekuvala kuhle, ngoba sicondziso sekugeleta kwepuleti levalve yesango kanye ne-medium yi-angle lemile, uma i-valve yesango ingekho endaweni ku-valve ipuleti le-valve switch, le-medium yenta i-valve ye-valve kuya ku-plate. kulimata sivalo sevalve yesango.
I-valve ye-flap, lephindze yatiwe ngekutsi yi-valve ye-flap, isakhiwo lesilula se-valve yekulawula, lengasetjentiswa kulawula ku-on/off kwephayiphi lephansi-yekucindzeteleka i-valve ye-butterfly lesemkhatsini ibhekisela engcenyeni yekuvala (disc noma ipuleti ye-butterfly) njenge-disc, lejikeleta i-valve shaft yekufeza kuvala kweluhlobo lwekulawula kanye ne kugeleta kwetinhlobo letehlukene tetintfo letimanti letifana nemoya, emanti, umfutfo, tintfo letehlukahlukene letiguculako, ludzaka, oyili, insimbi lesemantini kanye netintfo letikhipha imisebe. Ikakhulukati idlala indzima yekusika kanye nekucindzetela emaphayiphini. Lencenye yekuvula nekuvala ivalve ye butterfly yipuleti ye butterfly lemise njenge disc, lejikeleta i-axis yayo emtimbeni we valve, kwentela kufeza injongo yekuvula nekuvala noma kulungisa.
Lelipuleti le butterfly lichutjwa sicu se valve, futsi uma lijika nga 90°, lingacedza kuvulwa nekuvalwa. Ngekushintja i-angle yekuphambuka kweluvivane, lizinga lekugeleza le-medium lingalawulwa.
Timo tekusebenta kanye nendlela lesemkhatsini:Ivalvu yevivaneilungele kutfutsa emaphayiphi etinhlobonhlobo tetindzaba letigugile naletingagcobi etinhlelo tebunjiniyela letifana netitofu, igesi yemalahle, igesi yemvelo, igesi yaphethiloli lesemantini, igesi yelidolobha, umoya loshisako nalobandzile, kuncibilikisa ngemakhemikhali kanye nekukhicita emandla kusetjentiswa kwemvelo kuvikelwa kwemvelo, kwakha kuniketwa kwemanti kanye nekugeleta kwemanti, njll.
I-valve yesango (i-valve yesango) iyincenye levulekile nekuvala yesango, indlela yekuhamba kwesango icondzile esicondzisweni se-fluid, i-valve yesango ingavulwa kuphela futsi ivalwe ngalokuphelele, kungakhululeki kwemapharamitha emnyango kwehlukile, kuvame kuba ngu-5 °, lapho lizinga lekushisa lelisemkhatsini lingaphakeme, kungu 2 ′ 2. Kute kwentiwe ncono kukhicitwa kwayo kanye nekwenta kuphambuka kwe engela yendzawo yekuvala enchubeni yekucubungula, loluhlobo lwemvu lubitwa ngekutsi yi elastic ram.
Ngesikhatsi i .Ivalvu yesangoivaliwe, lendzawo yekuvala ingatsembela kuphela ekucindzetelekeni lokusemkhatsini kutsi ivale, lokusho kutsi, ithembele kuphela ekucindzetelekeni lokusemkhatsini kutsi icindzetele indzawo yekuvala yemvu kuya esihlalweni sevalve ngakulolunye luhlangotsi kucinisekisa kuvalwa kwendzawo yekuvala, lokuyintfo letivalako. Emavalvu lamaningi esango avalwa ngemandla, lokusho kutsi, uma levalve ivaliwe, le ram kumele icindetelwe ngemandla esihlalweni sevalve ngemandla langaphandle kwentela kucinisekisa kucina kwendzawo yekuvala.
Imodi yekuhamba: Ipuleti lesango le valve yesango ihamba emgceni locondzile nesicu se valve, lephindze ibitwe ngekutsi yi valve yesango levulekile yendvuku. Imvamisa kunentambo ye-trapezoidal kulendvuku yekuphakamisa, nge-nut lesetulu kwe-valve kanye ne-groove yekucondzisa emtimbeni we-valve, kunyakata lokujikeletako kuyashintjwa kube kunyakata lokusemgceni, lokusho kutsi, i-torque yekusebenta iyashintjwa ibe yi-thrust yekusebenta. Uma ivalve ivulwa, uma kuphakama kwekuphakamisa inkunzi kulingana ne 1:1 tikhatsi tebubanti bevalve, kugeleta kwemanti akuvinjelwa ngalokuphelele, kepha lesikhundla angeke sigadvwe ngesikhatsi sekusebenta. Ekusetjentisweni mbamba, imakwe yi vertex yesicu, lokusho kutsi, sikhundla lesingeke sivulwe, njengesikhundla sayo lesivulekile ngalokuphelele. Kute kulandziswe ngesimo sekuvala sekushintja kwekushisa, kuvame kuvulwa endzaweni ye apex, bese kubuyiselwa emuva ku 1/2-1 turn njengendzawo ye valve levulekile ngalokuphelele. Ngako-ke, sikhundla lesivulekile ngalokuphelele se-valve sincunywa sikhundla se-ram (okusho kutsi stroke). Lenye nut yesicu sevalve yesango ikhona esangweni, bese lisondvo lesandla liyajikeleta kwentela kushayela sicu sevalve kutsi sijikelete, bese ipuleti lesango liyaphakanyiswa, levalve ibitwa ngekutsi yivalve yesango lendvuku lejikeletako noma ivalve yesango lendvuku lemnyama.
