Emavalvu evivane tilungele emaphayiphi latfutsa imidiya leyehlukahlukene legugako nalengagcobi lesemantini etinhlelo tebunjiniyela letifana negesi yemalahle, igesi yemvelo, igesi yaphethiloli lesemantini, igesi yelidolobha, umoya loshisako nalobandzelako, kuncibilikisa ngemakhemikhali, kukhicita emandla kanye nekuvikela imvelo, futsi tisetjentiselwa kulungisa nekunciphisa imidiya.
Emavalvu evivane tilungele kulawulwa kwekugeleza. Ngenca yekutsi kulahlekelwa kwemfutfo we-valve ye-butterfly ephayiphini kukhulu kakhulu, cishe katsatfu kutsi kwe-valve yesango, uma ukhetsa i-valve ye-butterfly, umtselela weluhlelo lwemaphayiphi ngekulahlekelwa kwemfutfo kufanele ucatshangelwe ngalokuphelele, kanye nekucinisa kwepuleti ye-butterfly kutsi imelane nemfutfo we-beline medium kufanele uphindze ucabangele. kuya ecasini. Ngetulu kwaloko, imikhawulo lokushisa lokusebenta kwetintfo tesihlalo se-elastomeric ngesikhatsi sekushisa lokuphakeme kumele kuphindze kucatshangelwe.
Budze besakhiwo kanye nebudze bonkhe beivalvi yevivanetincane, sivinini sekuvula nekuvala siyashesha, futsi sinetimphawu letinhle tekulawula emanti. Umtsetfo wesakhiwo se-valve ye-butterfly ulungele kakhulu kwenta emavalvu lamakhulu-diameter. Ngesikhatsi i .ivalvu yevivane kuyadzingeka kutsi isetjentiselwe kulawula kugeleta, intfo lebaluleke kakhulu kutsi ukhetse kahle bukhulu kanye neluhlobo lwevalve ye butterfly kute ikhone kusebenta kahle futsi ngemphumelelo.
Ngalokuvamile, ekucindzeteleni, kulawula kulawula kanye neludzaka lolusemkhatsini, budze besakhiwo lesifishane kanye nekuvula nekuvala lokusheshako (1/4r) kuyadzingeka. Kuncishiswa kwemfutfo lophansi (umfutfo lomncane wemehluko), kunconywa kutsi kusetjentiswe ivalvu yeluvivane.Ivalvu yevivaneingasetjentiswa ekulungiseni tikhundla letimbili, umsele lomncane, umsindvo lophansi, cavitation kanye ne gasification, inani elincane lokuvuza emoyeni, kanye abrasive medium.
I clokusemkhatsini ivalvu yevivane ilungele emanti lahlobile, imfucuza, emanti elwandle, emanti laneluswayi, umfutfo, igesi yemvelo, kudla, imitsi, oyili kanye netinhlobonhlobo te Acid-base kanye nalamanye emaphayiphi.
Ivalvu levivane levaliwe ngendlela lethambile ilungele kuvulwa nekuvalwa kwetindlela letimbili kanye nekulungisa emaphayiphi ekungenisa umoya kanye nekususa lutfuli futsi isetjentiswa kakhulu kumaphayiphi egesi kanye netindlela temanti tekukhicita tinsimbi, imboni lelula, emandla agezi, kanye netinhlelo te-petrochemical.
