Ukusetshenziswa kwe-butterfly valve kanye ne-valve yesango ngaphansi kwezimo ezihlukene zokusebenza

I-valve yesango futhiuvemvane valve zombili zidlala indima yokushintsha kanye nokulawula ukugeleza ekusetshenzisweni kwamapayipi.Yiqiniso, kusekhona indlela ekukhethweni kwe-butterfly valve ne-valve yesango.Ukuze kuncishiswe ukujula kokumbozwa kwenhlabathi yepayipi kunethiwekhi yokuphakelwa kwamanzi, amapayipi ngokuvamile amakhulu amakhulu afakwe amavalvu ovemvane, anomthelela omncane ekujuleni kokumboza inhlabathi, futhi alwela ukukhetha amavalvu esango.

Uyini umehluko phakathi kwe-valve ye-butterfly ne-valve yesango?

Ngokusho komsebenzi nokusetshenziswa kwe-valve yesango kanye ne-butterfly valve, i-valve yesango inokumelana nokugeleza okuncane nokusebenza okuhle kokuvala.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 levalvu lidlidlizele., Kulula ukulimaza uphawu lwe-valve yesango.I-Butterfly valve, eyaziwa nangokuthi i-flap valve, iwuhlobo lwevalve elawulayo enesakhiwo esilula.I-valve yovemvane engase isetshenziselwe ukulawula lapho uvala khona ipayipi elinomfutho ophansi 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 eyonakalisayo ehlukahlukene, udaka, uwoyela, insimbi ewuketshezi kanye nemidiya ekhipha imisebe.Idlala kakhulu indima yokusika kanye nokuphonseka epayipini.I-valve uvemvane evula futhi evala ingxenye iyipuleti uvemvane okumise okwediski, elizungeza i-eksisi yalo emzimbeni wevalvu ukufeza injongo yokuvula nokuvala noma ukulungisa.Ipuleti uvemvane lishayelwa isiqu valve.Uma ifinyelela 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. , ukwakha amanzi kanye ne-drainage, njll. Epayipini le-medium, isetshenziselwa ukulungisa nokusika ukugeleza kwe-medium.

I-valve yesango inesango lelungu lokuvula nokuvala, isiqondiso sokunyakaza kwesango sibhekene nesiqondiso soketshezi, futhi i-valve yesango ingavulwa ngokugcwele futhi ivalwe ngokugcwele.Ukuthuthukisa ukwenziwa kwayoor ikhono futhi wenze ukuchezuka kwe-engeli 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 le-valve yesango lihamba ngendlela eqondile nesiqu se-valve, ebizwa nangokuthiOS&Y i-valve yesango.Ngokuvamile, kunemicu ye-trapezoidal ku-lift rod.Ngenati elingaphezulu kwevalvu kanye negroove eqondisayo emzimbeni wevalvu, ukunyakaza okujikelezayo kuguqulwa kube ukunyakaza okuqondile, okungukuthi, i-torque yokusebenza iguqulwa ibe i-thrust yokusebenza.Lapho i-valve ivuliwe, lapho ukuphakama kokuphakama kwesango kufana nezikhathi ezingu-1: 1 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 ngenxa yezinguquko zokushisa, ngokuvamile ivulwa 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, ukushaywa).Amanye amantongomane we-valve yesango abekwe esangweni, futhi ukuzungezisa kwesondo lesandla kuqhuba isiqu se-valve ukuze sijikeleze, okwenza isango liphakame.Lolu hlobo lwe-valve lubizwa ngokuthi i-Rotary stem gate valve nomaI-NRS i-valve yesango.
