I-valve yesango futhiivalvu yebhabhathane kokubili kudlala indima yokushintsha nokulawula ukugeleza kokusetshenziswa kwephayiphi. Yiqiniso, kusenendlela enqubweni yokukhetha ivalvu yebhabhathane kanye nevalvu yesango. Ukuze kuncishiswe ukujula kokumbozwa kwenhlabathi yephayiphi kunethiwekhi yokuphakelwa kwamanzi, ngokuvamile amaphayiphi amakhulu anobubanzi afakwe amavalvu ebhabhathane, angenawo umthelela omkhulu ekujuleni kokumbozwa kwenhlabathi, futhi alwela ukukhetha amavalvu esango.
Uyini umehluko phakathi kwevalvu yebhabhathane nevalvu yesango?
Ngokusho komsebenzi kanye nokusetshenziswa kwe-valve yesango kanye ne-valve ye-butterfly, i-valve yesango inokumelana okuncane kokugeleza kanye nokusebenza okuhle kokuvala. Ngenxa yokuthi indlela yokugeleza kwepuleti ye-valve yesango kanye ne-medium isendaweni eqondile, uma i-valve yesango ingashintshiwe endaweni yayo epuletini ye-valve, ukukhuhla i-medium epuletini ye-valve kuzokwenza ipuleti ye-valve idlidlize. , Kulula ukulimaza uphawu lwe-valve yesango. I-valve ye-Butterfly, eyaziwa nangokuthi i-flap valve, uhlobo lwe-valve elawulayo enesakhiwo esilula. I-valve ye-Butterfly engasetshenziswa ukulawula i-in-off ye-medium yepayipi elinomfutho ophansi isho ukuthi ilungu lokuvala (i-disc noma ipuleti le-butterfly) liyi-disc, ejikeleza umgodi we-valve ukuze kufezwe ukuvulwa nokuvalwa. I-valve engasetshenziswa ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi njengomoya, amanzi, umusi, imidiya ehlukahlukene ebolile, udaka, uwoyela, insimbi ewuketshezi kanye nemidiya enemisebe. Idlala indima enkulu yokusika nokugoqa ipayipi. Ingxenye yokuvula nokuvala ivalvu yebhabhathane iyipuleti lebhabhathane elimise okwediski, elijikeleza i-axis yalo emzimbeni wevalvu ukuze lifeze injongo yokuvula nokuvala noma ukulungisa. Ipuleti lebhabhathane liqhutshwa yisiqu sevalvu. Uma lifinyelela eminyakeni engama-90°, ingaqeda ukuvula nokuvala okukodwa. Ngokushintsha i-engeli yokuphambuka kwediski, ukugeleza kwe-medium kungalawulwa.
Izimo zokusebenza kanye nendawo yokusebenza: I-Butterfly valve ifanele ukuthutha uketshezi oluhlukahlukene olubolayo nolungaboli ezinhlelweni zobunjiniyela ezifana nomkhiqizi, igesi yamalahle, igesi yemvelo, igesi kaphethiloli encibilikisiwe, igesi yedolobha, umoya oshisayo nobandayo, ukuncibilikisa amakhemikhali kanye nokuvikelwa kwemvelo kokukhiqizwa kwamandla, ukuhlinzekwa kwamanzi okwakha kanye nokugeleza kwamanzi, njll. Epayipini lendawo yokusebenza, isetshenziselwa ukulungisa nokunqamula ukuhamba kwendawo yokusebenza.
Ivalvu yesango inesango eliyilungu lokuvula nokuvala, indlela yokuhamba kwesango iqonde ngqo ohlangothini loketshezi, futhi ivalvu yesango ingavulwa ngokugcwele futhi ivalwe ngokuphelele kuphela. Ukuze kuthuthukiswe umkhiqizo wayo.or ikhono kanye nokulungisa ukuphambuka kwe-engeli yobuso bokuvala ngesikhathi sokucubungula, leli sango libizwa ngokuthi isango elinwebekayo.
Uma ivalvu yesango ivaliwe, indawo yokuvala ingathembela kuphela ekucindezelweni okuphakathi ukuze ivalwe, okungukuthi, ithembele kuphela ekucindezelweni okuphakathi ukuze icindezele indawo yokuvala yesango esihlalweni sevalvu ngakolunye uhlangothi ukuqinisekisa ukuvalwa kwendawo yokuvala, okuzivala ngokwayo. Amavalvu amaningi esango avalwa ngenkani, okungukuthi, lapho ivalvu ivaliwe, isango kumele liphoqelelwe esihlalweni sevalvu ngamandla angaphandle ukuqinisekisa ukuqina kwendawo yokuvala.
Imodi yokunyakaza: Isango le-valve yesango lihamba ngendlela eqondile nesiqu se-valve, esibizwa nangokuthiI-OS&Y ivalvu yesango. Ngokuvamile, kunezintambo ze-trapezoidal endukwini yokuphakamisa. Nge-nut phezulu kwe-valve kanye nomsele wokuqondisa emzimbeni we-valve, ukunyakaza okujikelezayo kuguqulwa kube ukunyakaza okuqondile, okungukuthi, i-torque yokusebenza ishintshwa ibe yi-thrust yokusebenza. Lapho i-valve ivulwa, lapho ukuphakama kokuphakamisa kwesango kulingana nobubanzi be-valve obuphindwe ka-1:1, isiteshi soketshezi asivimbeki nhlobo, kodwa lesi sikhundla asinakubhekwa ngesikhathi sokusebenza. Ekusetshenzisweni kwangempela, i-top ye-valve stem isetshenziswa njengesibonakaliso, okungukuthi, indawo lapho ingenakuvulwa khona, njengendawo yayo evulekile ngokuphelele. Ukuze kucatshangelwe isenzakalo sokukhiya ngenxa yokushintsha kwezinga lokushisa, ivame ukuvulwa iye endaweni ephezulu, bese ibuyela emuva ekujikeni okungu-1/2-1, njengendawo ye-valve evulekile ngokuphelele. Ngakho-ke, indawo evulekile ngokuphelele ye-valve inqunywa ngokuya ngesimo sesango (okungukuthi i-stroke). Amanye ama-strand valve stem nuts abekwe esangweni, futhi ukujikeleza kwesondo lesandla kuqhuba i-valve stem ukuthi ijikeleze, okwenza isango liphakame. Lolu hlobo lwe-valve lubizwa ngokuthi i-Rotary stem gate valve nomaI-NRS ivalvu yesango.
