Ngokomsebenzi nokusetshenziswa kwei-valve yesangofuthiuvemvane valve, i-valve yesango inokumelana nokugeleza okuncane nokusebenza kahle kokuvala uphawu.Ngenxa yokuthi ukugeleza kwepuleti le-valve yesango kanye nendawo emaphakathi ku-engeli eqondile, uma i-valve yesango ingashintshwanga endaweni yayo ku-valve plate, ukukhuhla okuphakathi nendawo epuleti levalvu kuzokwenza ipuleti le-valve lidlidlizele., Kulula ukulimaza uphawu lwe-valve yesango.
Butterfly valve, eyaziwa nangokuthii-valve ye-flap, luhlobo lwe-valve yokulawula enesakhiwo esilula.I-valve yovemvane engase isetshenziselwe ukulawula lapho ucisha ipayipi lokucindezela okuphansi kusho ukuthi ilungu elivalayo (idiski noma ipuleti uvemvane) iyidiski, ezungeza i-valve shaft ukuze ifinyelele ukuvuleka nokuvala.Ivalvu engasetshenziswa ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi olunjengomoya, amanzi, isitimu, imidiya edlayo ehlukahlukene, udaka, uwoyela, insimbi ewuketshezi kanye nemidiya ekhipha imisebe.Idlala kakhulu indima yokusika kanye nokuphonseka epayipini.Ivalve uvemvane evula futhi evala ingxenye aipuleti uvemvane emise okwe-disc, ezungeza i-axis yayo emzimbeni we-valve ukufeza injongo yokuvula nokuvala noma ukulungisa.
Ipuleti uvemvane lishayelwa isiqu valve.Uma ijika ku-90°, ingaqeda ukuvula nokuvala okukodwa.Ngokushintsha i-deflection angle ye-disc, ukugeleza kwe-medium kungalawulwa.
Izimo zokusebenza nendawo ephakathi: Ivalvu yovemvane ilungele ukudlulisa uketshezi oluhlukahlukene olubolayo nolungagqwali ezinhlelweni zobunjiniyela njengomkhiqizi, igesi yamalahle, igesi yemvelo, igesi ye-petroleum ewuketshezi, igesi yedolobha, umoya oshisayo nobandayo, ukuncibilika kwamakhemikhali nokuvikelwa kwemvelo kokuphehla amandla. , ibhilidiukuhlinzekwa kwamanzi kanye nokukhipha amanzi, njll. Epayipini le-medium, isetshenziselwa ukulungisa nokusika ukugeleza kwe-medium.
Ii-valve yesangokuyisango lokuvula nokuvala, isiqondiso sokunyakaza kwesango sibhekene nesiqondiso soketshezi, futhi i-valve yesango ingavulwa ngokugcwele futhi ivalwe ngokugcwele.Ukuze uthuthukise ukwenziwa kwayo futhi wenze ukuchezuka kwe-engeli yendawo yokuvala uphawu ngesikhathi sokucubungula, leli sango libizwa ngokuthi isango elinwebekayo.
Lapho i-valve yesango ivaliwe, indawo yokuvala ingancika kuphela ekucindezelweni okuphakathi ukuze ivalwe, okungukuthi, incike kuphela ekucindezelweni okuphakathi ukuze ucindezele indawo yokuvala yesango esihlalweni se-valve ngakolunye uhlangothi ukuze uqinisekise ukuvala indawo evalayo, ezivalekayo.Ama-valve amaningi esango avaliwe ngenkani, okungukuthi, lapho i-valve ivaliwe, isango kufanele liphoqelelwe ngokumelene nesihlalo se-valve ngamandla angaphandle ukuze kuqinisekiswe ukuqina kwendawo yokuvala.
Imodi yokunyakaza: Isango levalvu yesango lihamba ngendlela eqondile nesiqu se-valve, ebizwa nangokuthi ai-valve yesango ye-stem ekhuphukayo.Ngokuvamile, kunemicu ye-trapezoidal ku-lift rod.Ngenati elingaphezulu kwevalvu kanye negroove eqondisayo emzimbeni we-valve, ukunyakaza okujikelezayo kuguqulwa kube ukunyakaza okulandelanayo, okungukuthi, i-torque yokusebenza iguqulwa ibe i-thrust yokusebenza.Lapho i-valve ivuliwe, lapho ukuphakama kokuphakama kwesango lilingana no-1: 1 izikhathi ububanzi be-valve, isiteshi samanzi singenasici ngokuphelele, kodwa lesi sikhundla asikwazi ukuqapha ngesikhathi sokusebenza.Ekusetshenzisweni kwangempela, i-apex ye-valve stem isetshenziswa njengesibonakaliso, okungukuthi, isikhundla lapho singakwazi ukuvulwa khona, njengendawo yayo evulekile ngokugcwele.Ukuze ucabangele into yokukhiya okubangelwa ukushintsha kwezinga lokushisa, ngokuvamile ivuliwe endaweni ephezulu, bese ibuyela ku-1 / 2-1 ukuphenduka, njengesikhundla se-valve evulekile ngokugcwele.Ngakho-ke, indawo evulekile ngokugcwele ye-valve inqunywa ngokusho kwendawo yesango (okungukuthi i-stroke).Amanye amantongomane we-valve wesango abekwe esangweni, futhi ukuzungezisa kwesondo lesandla kuqhuba isiqu se-valve ukuthi sijikeleze, futhi isango liyaphakanyiswa.Lolu hlobo lwe-valve lubizwa ngokuthiI-valve yesango le-Rotary stem or i-valve yesango ye-stem efihliwe.
