Ivalvu yesango futsiivalvu yevivane bobabili badlala indzima yekushintja nekulawula kugeleta ekusetjentisweni kwemaphayiphi. Kuliciniso, kusekhona indlela enchubeni yekukhetsa valve butterfly kanye valve esango. Kute kuncishiswe kujula kwekumbonya umhlabatsi weliphayiphi kunethiwekhi yekuniketa emanti, ngalokuvamile emaphayiphi lamakhulu lane diameter afakwe emavalvu e butterfly, lanemtselela lomncane ekujuleni kwekumbonya umhlabatsi, futsi alwela kukhetsa emavalvu esango.
Yini umehluko emkhatsini valve butterfly kanye valve isango?
Ngekuya kwemsebenti kanye nekusetjentiswa kwe valve yesango kanye ne valve ye butterfly, le valve yesango inekumelana lokuncane kwekugeleza kanye nekusebenta kahle kwekuvala. Ngenca yekutsi indlela yekugeleta kwelipuleti le valve yesango kanye ne medium ise engeleni lemile, uma le valve yesango ingashintjwa endzaweni yayo epuletini le valve, kuhlantwa kwe medium epuletini le valve kutawenta kutsi le valve idvumate. , Kulula kulimata sivalo sevalve yesango. Ivalve yeluvevane, lephindze yatiwe ngekutsi yivalve ye-flap, luhlobo lwevalve yekulawula lenesakhiwo lesilula. I-valve ye-butterfly lengasetjentiswa kulawula ku-on-off kwemkhatsi wephayiphi lenemfutfo lophansi kusho kutsi lilunga lekuvala (disc noma ipuleti le-butterfly) liyi-disc, lejikeleta ishaft yevalve kwentela kufeza kuvulwa nekuvalwa. Ivalve lengasetjentiswa kulawula kuhamba kwetinhlobo letehlukene tetintfo letifana nemoya, emanti, umfutfo, tintfo letehlukene 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 inhloso yekuvula nekuvala noma kulungisa. Ipuleti levivane liqhutshwa sicu sevalve. Uma ngabe ihlanganisa iminyaka lengu 90°, ingacedza kuvula nekuvala lokukodwa. Ngekushintja i-angle yekuphambuka kwe-disc, kugeleza kwe-medium kungalawulwa.
Timo tekusebenta kanye nendzawo lesemkhatsini: Butterfly valve ilungele kudlulisa tintfo letehlukahlukene letiguculako naletingagucuki etinhlelo tebunjiniyela letifana nemkhiciti, igesi yemalahle, igesi yemvelo, igesi yaphethiloli lesemantini, igesi yedolobha, umoya loshisako nalobandzile, kuncibilikisa emakhemikhali kanye nekukhicita emandla water draina supply of the buil. medium, isetjentiselwa kulungisa kanye nekunciphisa kugeleta kwe medium.
Le valve yesango inesango lelilunga lelivulako nalelivalako, indlela yekuhamba kwelisango imile ngendlela yeludzaka, futsi le valve yesango ingavulwa ngalokuphelele futsi ivalwe ngalokuphelele kuphela. Kute kwentiwe ncono kukhicitwa kwayo .or ikhono kanye nekwakha kuphambuka kwe-angle yemhlabatsi wekuvala ngesikhatsi sekucubungula, lelisango libitwa ngekutsi lisango le-elastic.
Uma ivalve yesango ivaliwe, indzawo yekuvala ingatsembela kuphela kucindzeteleka lokusemkhatsini kuvala, lokusho kutsi, kuphela kwetsembela kucindzeteleka lokusemkhatsini kucindzetela indzawo yekuvala yesango kuya esihlalweni sevalve ngakulolunye luhlangotsi kucinisekisa kuvalwa kwendzawo yekuvala, lokuyintfo letivalako. Emavalvu lamaningi esango avalwa ngemandla, lokusho kutsi, uma levalve ivaliwe, lelisango kumele liphocelelelwe esihlalweni sevalve ngemandla langaphandle kwentela kucinisekisa kucina kwendzawo yekuvala.
Imodi yekuhamba: Lisango levalve yesango lihamba emgceni locondzile nesicu sevalve, lesiphindze sibitwe ngekutsi .OS&Y Ivalvu yesango. Imvamisa, kunemicu 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 kwesango kulingana ne 1:1 tikhatsi tebubanti bevalve, umzila wemanti awuvinjelwa ngalokuphelele, kepha lesikhundla angeke sigadvwe ngesikhatsi sekusebenta. Ekusetjentisweni mbamba, i-apex yesicu sevalve isetjentiswa njengeluphawu, lokusho kutsi, indzawo lapho ingavulwa khona, njengendzawo yayo levulekile ngalokuphelele. Kute kucatshangelwe lesimo sekuvala ngenca yetingucuko tekushisa, kuvame kuvulwa kuya endzaweni lesetulu, bese kubuyela emuva ku 1/2-1 turn, njengendzawo ye valve levulekile ngalokuphelele. Ngako-ke, sikhundla lesivulekile ngalokuphelele sevalve sincunywa ngekuya kwesikhundla sesango (okusho kutsi stroke). Lamanye emanti esicu se valve yesango abekwa esangweni, bese kujikeleta kwelisondvo lesandla kwenta kutsi sicu se valve sijikelete, lokwenta kutsi lisango liphakamise. Loluhlobo lwevalve lubitwa ngekutsi yivalve yesango le-Rotary stem noma .NRS Ivalvu yesango.
