1. Umgomo wokuvalwa kweTaikei-valve yebhola elintantayo
Ingxenye evulayo nevalayo ye-Taike Floating Ball Valve iyindilinga enembobo edlulayo elingana nobubanzi bepayipi phakathi. Isihlalo sokuvala esenziwe nge-PTFE sibekwe ekugcineni kwe-inlet kanye nendawo yokuphuma, equkethwe ku-valve yensimbi. Emzimbeni, lapho imbobo ephumela endimeni idlula umgudu wepayipi, i-valve isesimweni esivulekile; lapho imbobo edlula kuyindilinga ibheke kumzila wepayipi, i-valve isesimweni esivaliwe. I-valve iphenduka isuke ekuvulekeni iye ekuvaleni, noma isuka ekuvaleni iye ekuvulekeni, ibhola lijika libe ngu-90°.
Lapho i-valve yebhola isesimweni esivaliwe, ingcindezi emaphakathi ekugcineni kwe-inlet isebenza ebholeni, ikhiqiza amandla okusunduza ibhola, ukuze ibhola licindezele ngokuqinile isihlalo sokuvala ekugcineni, futhi kukhiqizwa ukucindezeleka kokuxhumana. endaweni eyi-conical yesihlalo sokuvala ukwakha indawo yokuxhumana Amandla ngeyunithi ngayinye yendawo yokuxhumana abizwa ngokuthi ingcindezi ethile yokusebenza q yesivalo sevalvu. Uma lokhu kucindezela okuqondile kukhulu kunokucindezela okuqondile okudingekayo ukuze kufakwe uphawu, i-valve ithola uphawu olusebenzayo. Lolu hlobo lwendlela yokuvala enganciki emandleni angaphandle, luvalwa ngomfutho ophakathi, lubizwa ngokuthi ukuzivala okuphakathi nendawo.
Kufanele kuphawulwe ukuthi valve bendabuko ezifanaama-valve embulunga, ama-valve esango, umugqa ophakathiizivalo uvemvane, futhi ama-valve amapulaki athembele emandleni angaphandle ukuze asebenze esihlalweni se-valve ukuze athole uphawu oluthembekile. Uphawu olutholwe ngamandla angaphandle lubizwa ngokuthi uphawu oluphoqelelwe. Amandla okuvalwa okuphoqelekile asetshenziswa ngaphandle ayenzeka ngokungahleliwe futhi awaqiniseki, angahambisani nokusetshenziswa isikhathi eside kwe-valve. Umgomo wokuvala we-Taike ball valve ungamandla asebenza esihlalweni sokuvala, akhiqizwa ukucindezela kwe-medium. La mandla azinzile, angalawulwa, futhi anqunywe ngokuklama.
2. Izici zesakhiwo se-valve ye-Taike elintantayo
(1) Ukuze kuqinisekiswe ukuthi imbulunga ingakwazi ukukhiqiza amandla okuxhumana lapho imbulunga isesimweni esivaliwe, imbulunga kufanele ibe seduze nesihlalo sokuvala lapho ivalvu ihlanganiswa kusenesikhathi, futhi ukuphazanyiswa kuyadingeka ukuze kukhiqizwe Ukucindezela kwesilinganiso sangaphambi kokuqina, lokhu kucindezela kwesilinganiso sangaphambi kokuqina Kungu-0.1 izikhathi zokucindezela kokusebenza futhi hhayi ngaphansi kuka-2MPa. Ukutholwa kwalesi silinganiso sokulayisha kuqala kuqinisekiswa ngokuphelele ubukhulu bejometri bomklamo. Uma ukuphakama okukhululekile ngemva kokuhlanganiswa kwe-sphere kanye nezihlalo zokuvala zokungena nokuphumayo kungu-A; ngemva kokuba imizimba ye-valve yesokunxele nesokudla isihlanganisiwe, ingaphakathi le-valve liqukethe i-sphere futhi ububanzi besihlalo sokuvala singu-B, khona-ke ingcindezi edingekayo yokulayisha kuqala ikhiqizwa ngemva kokuhlanganiswa. Uma inzuzo ingu-C, kufanele yenelise: AB=C. Leli nani elingu-C kufanele liqinisekiswe ubukhulu bejiyomethri bezingxenye ezicutshunguliwe. Kungacatshangwa ukuthi lokhu kugxambukela C kunzima ukunquma nokuqinisekisa. Ubukhulu bevelu yokuphazamiseka bunquma ngokuqondile ukusebenza kokuvala kanye ne-torque yokusebenza kwe-valve.
(2) Kufanele kuphawulwe ngokukhethekile ukuthi i-valve yebhola elintantayo yasekhaya yasekuqaleni kwakunzima ukuyilawula ngenxa yenani lokuphazamiseka phakathi nokuhlanganisa, futhi yayivame ukulungiswa ngama-gaskets. Abakhiqizi abaningi baze babhekisela kule gasket njenge-gasket yokulungisa encwadini. Ngale ndlela, kukhona igebe elithile phakathi kwezindiza zokuxhuma zemizimba ye-valve eyinhloko kanye neyokusiza ngesikhathi somhlangano. Ukuba khona kwaleli gebe elithile kuzobangela ukuba amabhawodi axege ngenxa yokuguquguquka kwengcindezi emaphakathi nokushintshashintsha kwezinga lokushisa elisetshenziswayo, kanye nomthwalo wamapayipi angaphandle, futhi kubangele ukuba ivalvu ibe ngaphandle. ukuvuza.
(3) Uma i-valve isesimweni esivaliwe, amandla aphakathi nendawo ekugcineni kwe-inlet asebenza endaweni, okuzokwenza ukuthi kugudluke kancane isikhungo sejiyomethri se-sphere, esizobe sisondelene nesihlalo se-valve endaweni. ukuphela kwe-outlet futhi kwandise ingcindezi yokuxhumana ebhandeni lokuvala, ngaleyo ndlela uthole ukwethembeka. Uphawu; futhi amandla okuqinisa ngaphambili kwesihlalo se-valve ekugcineni kwe-inlet lapho ethintana nebhola azoncishiswa, okuzothinta ukusebenza kokuvala kwesihlalo sokufaka uphawu lokungena. Lolu hlobo lwesakhiwo se-valve yebhola i-valve yebhola enokususwa kancane enkabeni yejometri yendilinga ngaphansi kwezimo zokusebenza, ebizwa ngokuthi i-valve yebhola elintantayo. I-valve yebhola elintantayo ivalwe ngesihlalo esivalayo ekugcineni kwe-outlet, futhi akuqiniseki ukuthi isihlalo se-valve ekugcineni kokungena sinomsebenzi wokuvala yini.
(4) Isakhiwo se-valve yebhola elintantayo le-Taike li-bi-direction, okungukuthi, izikhombisi-ndlela ezimbili zokugeleza okuphakathi zingavalwa.
(5) Isihlalo sokuvala lapho ama-sphere axhunywe khona senziwe ngezinto ze-polymer. Uma ama-sphere ezungeza, ugesi omile ungase ukhiqizwe. Uma ingekho idizayini ekhethekile yesakhiwo-i-anti-static, ugesi omile unganqwabelana kuma-sphere.
(6) Ngevalvu enezihlalo ezimbili zokuvala, imbobo yevalvu ingase iqongelele okuphakathi. Okunye okuphakathi kungase kukhuphuke ngokungavamile ngenxa yezinguquko kuzinga lokushisa elizungezile nezimo zokusebenza, okubangela ukulimala emngceleni wokucindezela we-valve. Kufanele kuqashelwe.
