I-fluorine plastic futha valve, ivalve yeglobhu kanye nevalve yesango yimuphi umehluko? Yiziphi izinto ezijwayelekile ezisetshenziswa kumaphampu epulasitiki?

Iphampu yepulasitiki ye-fluorine ISEBENZISA ipulasitiki ye-fluorine evimbela ukubola, i-fluorine plastic alloy steel lining fluorine impahla yepulasitiki efana nokukhiqiza, abasebenzisi ekusebenziseni inqubo yokufaka, ngenxa yezidingo ezahlukene, isidingo sokufaka i-valve noma i-valve yesango, uyini umehluko phakathi kwalezi zinhlobo ezimbili zokusebenza kwe-valve, i-valve enqamuliwe, i-valve yesango, i-valve uvemvane, i-valve yokuhlola kanye ne-ball valve, njll. Lawa mavalvu abalulekile ezinhlotsheni ezahlukene zeyunithi yokulawula amapayipi manje. I-valve ngayinye ihlukile ngokubukeka, ukwakhiwa kanye nokusetshenziswa okusebenzayo. Kodwa i-valve yembulunga kanye ne-valve yesango esesimweni sokufana okuthile, ngasikhathi sinye isendleleni yokwenza i-truncation ngomsebenzi, ngakho-ke kuzoba nokuxhumana okuningi kwe-valve hhayi abangani abaningi abazodideka phakathi kwalokhu okubili. Eqinisweni, uma ubhekisisa kahle, umehluko phakathi kwamavalvu embulunga namavalvu esango mkhulu kakhulu. Lesi sihloko sethula ukuthi uyini umehluko phakathi kwe-valve yeglobhu ne-valve yesango.
Okokuqala, isimiso sokusebenza se-globe valve ne-valve yesango
Lapho i-valve yembulunga ivulwa futhi ivalwa, iwuhlobo lwesiqu esikhuphukayo, okusho ukuthi, phendula isondo lesandla, futhi isondo lesandla lizolandela isiqu ndawonye ukwenza ukujikeleza nokuphakamisa ukunyakaza. I-valve yesango iwukuzungezisa isondo lesandla, ukuze isiqu senze ukunyakaza kokuphakamisa, isondo lesandla ngokwalo limile lingashintshile. Amazinga okugeleza ayahluka, futhi ama-valve esango adinga ukuvuleka okugcwele noma ukuvaleka ngokugcwele, kuyilapho ama-globe valves awafuni. I-valve yokusika inezinhlinzeko zendlela yokungena nokuphuma; Ama-valve esango awanazo izidingo zendlela yokungena nokuphumayo. Ngaphezu kwalokho, i-valve yesango ivuliwe kuphela ngokugcwele noma ivaliwe ngokugcwele izifunda ezimbili, uhambo lokuvula nokuvala isango lukhulu kakhulu, isikhathi sokuvula nokuvala side. I-stroke yokunyakaza ye-valve plate ye-globe valve incane kakhulu, futhi i-valve plate ye-globe valve ingamiswa endaweni ethile ngesikhathi sokunyakaza ukuze yenze ukulawulwa kokugeleza. I-valve yesango ingasetshenziswa kuphela ukunqamula, awukho omunye umsebenzi.
Okwesibili, umehluko wokusebenza
I-valve ye-globe ingasetshenziselwa kokubili ukunqanyulwa nokulawula ukugeleza. Ukumelana noketshezi lwevalvu yembulunga kukhulu, kuyakhandla kakhulu lapho kuvulwa futhi ivala, kodwa ngenxa yokuthi ibanga lepuleti le-valve ukusuka endaweni yokuvala lifushane, ngakho-ke ukuvuleka nokuvala ukushaywa kufushane.
Ngenxa yokuthi i-valve yesango ingavuleka ngokugcwele futhi ivalwe ngokugcwele, ivuleke ngokuphelele, ukumelana nokugeleza okuphakathi esiteshini somzimba we-valve cishe ku-0, ngakho-ke ukuvulwa nokuvalwa kwe-valve yesango kuzosindisa kakhulu umsebenzi, kodwa ibanga. kusukela endaweni yokuvala ipuleti yesango ikude, isikhathi sokuvula nokuvala side.
Okwesithathu, isakhiwo
Isakhiwo se-valve yesango sizoba yinkimbinkimbi kakhulu kune-valve yembulunga, kusukela ekubukeni kwe-caliber efanayo, i-valve yesango iphakeme kune-valve yembulunga, i-valve yembulunga yinde kune-valve yesango. Ngaphezu kwalokho, i-valve yesango inamaphuzu wenduku ecacile futhi emnyama. I-valve ye-globe ayifuni.
Okwesine, vala
I-valve yokuvala i-valve core iyiphrofayili encane ye-trapezoidal (eqondile bheka ukuma kwe-valve core), iwela uma i-valve core, ukuvalwa kwe-valve (uma umehluko wengcindezi umkhulu, i-lax evaliwe, yebo, kodwa hlola umphumela ophambene muhle, isango lisohlangothini lwesango lenhliziyo ukuze livalwe, umphumela wokuvala ungcono kune-valve evaliwe, ukulahlekelwa kwe-valve core akufani ne-valve ye-globe valve evaliwe.
Eyesihlanu, ukufakwa kanye nesiqondiso sokugeleza
Endabeni yesikhala esilinganiselwe sokufaka, ukunakwa kufanele kukhokhwe ekukhetheni. I-valve yesango ingancika ekucindezelweni okuphakathi okuvalwe ngokuqinile ngendawo yokuvala, ukuze kuzuzwe umphumela wokungavuzi. Lapho uvula futhi uvala, indawo yokuvala ye-valve core kanye nesihlalo se-valve sihlale sithintana futhi sigudlana, ngakho-ke indawo yokuvala kulula ukugqoka. Uma i-valve yesango isiseduze nokuvalwa, umehluko wengcindezi phakathi kwephayiphi ngaphambili nangemuva mkhulu kakhulu, okwenza indawo yokuvala igqoke ibe bucayi kakhulu.
Umphumela wokugeleza kwe-valve yesango kuzo zombili izinkomba kuyafana, ukufakwa akunazo izidingo zokungenisa nokuthumela ngaphandle, okuphakathi kungageleza kuzo zombili izinkomba. I-VALVE Esikiwe IDINGA UKUFAKWA NGOKUQINILE ngokuhambisana nesiqondiso esimakwe umcibisholo womzimba we-valve. Kunemithethonqubo ecacile mayelana nesiqondiso sokungenisa nokuthumela ngaphandle kwevalvu enqamuliwe.
Ivalvu yembulunga iphansi phezulu, ngaphandle kukhona ipayipi elisobala akuwona umugqa ovundlile wesigaba. Ishaneli yevalvu yesango ikumugqa ovundlile. Ukushaywa kwama-valve esango kukhulu kunokwama-globe valves.
Ngokombono wokumelana nokugeleza ku-valve yesango elivulekile eligcwele ukumelana nokugeleza okuncane, ukumelana nokugeleza kwe-valve yokuhlola umthwalo. I-coefficient yokumelana nokugeleza kwe-valve yesango evamile imayelana ne-0.08 ~ 0.12, amandla okuvula nokuvala mancane, okuphakathi kungageleza ngezindlela ezimbili. Ukumelana nokugeleza kwe-valve yeglobu evamile izikhathi ezingu-3-5 kune-valve yesango. I-valve spool ye-valve ye-globe ithintwa kuphela nendawo yokuvala lapho ivalwe ngokuphelele, ngakho ukuguga kwendawo yokuvala kuncane kakhulu. Ngenxa yamandla amakhulu okugeleza, i-valve yembulunga edinga ukwengeza i-actuator kufanele inake ukulungiswa kwendlela yokulawula itorque.
Kunezindlela ezimbili zokufaka i-valve ye-globe, enye i-medium ingangena kusukela phansi kwe-spool, inzuzo ukuthi lapho i-valve ivaliwe, impande ye-pan ayikho ngaphansi kwengcindezi, inganweba impilo yesevisi yempande ye-pan. , futhi kungaba esimweni sokucindezela kwipayipi ngaphambi kwe-valve, ukushintshwa komsebenzi wempande ye-pan; Okubi ukuthi i-torque yokushayela ye-valve inkulu, cishe izikhathi ezingu-1 ukugeleza engxenyeni engenhla, futhi amandla e-axial we-valve stem makhulu, futhi i-valve stem kulula ukugoba. Ngakho-ke le ndlela ngokuvamile ifanelekela kuphela i-valve yeglobhu encane yezinga (i-DN50 ngezansi), i-DN200 ngaphezu kwevalvu yembulunga ikhethwa ekungeneni okuphakathi kusuka kule ndlela engenhla. (I-valve yeglobhu kagesi ngokuvamile isetshenziswa ukusuka kokuphakathi ukuya endleleni.) Ububi bokungena kusuka phezulu kuphambene ncamashi nendlela ephansi.
