Le khasiI-butterfly valveyasungulwa e-United States ngawo-1930. Kwangeniswa eJapan ngawo-1950s futhi kwakungasetshenziswa kabanzi eJapan kuze kube yi-1960s. Akudalwanga ezweni lami kuze kube yi-1970s. Izici eziphambili zama-butterfly valves yilezi: i-torque encane yokusebenza, isikhala esincane sokufaka nesisindo esikhanyayo. Ukuthatha i-DN1000 njengesibonelo,I-butterfly valveimayelana ne-2t, ngenkathiI-SAGE VALVVVEimayelana ne-3.5T. Le khasiI-butterfly valveKulula ukuhlanganisa namadivayisi ahlukahlukene weDrayivu futhi unokuqina okuhle nokwethembeka. Ububi be-butterfly ama-butterfly bavalwe ama-butterfly ama-butterfly ukuthi lapho kusetshenziselwa ukudonsa, ukuvalwa kwezokwenzeka ngenxa yokusetshenziswa okungafanele, okwenza isihlalo senjoloba siye silimele silimele. Ngakho-ke, ungayikhetha kanjani kahle incike kuncike ezimeni zokusebenza. Ubudlelwano phakathi kokuvulwa kwe-valve butterfly kanye nenani lokugeleza ngokuyisisekelo liqondile. Uma kusetshenziselwa ukulawula isilinganiso sokugeleza, izici zayo zokugeleza nazo zihlobene kakhulu nokulimala kwepayipi. Isibonelo, uma i-valve caliber kanye nefomu lamapayipi amabili liyafana, kepha okuphathelene nokulahlekelwa kwepayipi kuhlukile, izinga lokugeleza kwe-valve lizohluka kakhulu. Uma i-valve isesimweni sokupholisiswa okukhulu okupholile, i-cavitation ithambekele ngemuva ngemuva kwepuleti le-valve, elingalimaza i-valve. Ngokuvamile kusetshenziswa ngaphandle kwe-15 °. LaphoI-butterfly valveKusekuqaleni okuphakathi, ukwakheka kokuvula okwakhiwa ngumzimba we-valve kanye nokuphela kwangaphambili kweplate yevemvane kugxile emgodini we-valve, kanti amazwe ahlukene akhiwa ezinhlangothini zombili. Ukuphela kwangaphambili kwepuleti levemvane ngakolunye uhlangothi kuhamba lapho kuqubuka ukugeleza kwamanzi, futhi ngakolunye uhlangothi kuhamba lapho kuqubuka ukugeleza kwamanzi. Ngakho-ke, umzimba we-valve kanye nepuleti le-valve ngakolunye uhlangothi kwakha ukuvulwa okwenziwe ngombala, futhi ngakolunye uhlangothi kufana nokuvulwa okubunjiwe komgodi. Uhlangothi lwe-nozzle lunesilinganiso esisheshayo sokugeleza kunesihlangothi esisheshayo, futhi ingcindezi engemihle izokhiqizwa ngaphansi kwe-valve ohlangothini lwe-throttle, futhi uphawu lwenjoloba luvame ukuwela. I-torque esebenzayo yeI-butterfly valveIyahluka ngenxa yokuvuleka okuhlukile kanye nemikhombandlela yokuvula nokuvala ye-valve. I-torque ekhiqizwe umehluko phakathi kwamakhanda amanzi aphezulu nangaphansi e-valve yamanzi avundlile, ikakhulukazi i-valve enkulu, ngenxa yokujula kwamanzi, akunakunakwa. Ngaphezu kwalokho, lapho i-elbow ifakiwe ohlangothini lwe-valve, kwakhiwa ukugeleza kwe-bias, futhi i-torque izokwanda. Lapho i-valve isekuvuleni okuphakathi, indlela yokusebenza idinga ukuzivalela ngenxa yesenzo se-torque yamanzi.
I-China inamaketanga amaningi emboni we-valve, kepha akuwona amandla e-valve. Ngokuvamile, izwe lami lingene ezikhundleni zamandla we-valve emhlabeni, kepha ngokwekhwalithi yomkhiqizo, izwe lami lisekude kakhulu ekubeni namandla e-valve. Umkhakha usenokuhlushwa okuphansi okuphansi, amakhono we-R & D aphansi ahambelana nemikhiqizo ephezulu, kanye nezinga lobuchwepheshe obuphansi embonini ye-valve, kanye nokushoda kwezohwebo okuthekelisayo kuyaqhubeka ukwanda. Nakanjani izinkampani ze-valve eziningi ezingasinda ngempela emakethe. Kodwa-ke, lokhu kushaqeka okusheshayo embonini yama-valve kuzoletha amathuba amakhulu, futhi umphumela wokushaqeka uzokwenza ukuthi ukusebenza kwemakethe kuzokwenza kube nengqondo. Umgwaqo oya endaweni yokusatshalaliswa kwama-valves aphezulu kakhulu "bumpy". Izingxenye eziyisisekelo ziye zaba ukushiyeka okuvimbela ukuthuthukiswa komkhakha wezwe lakuleli lize eliphezulu. Ngesikhathi sohlelo lweminyaka eyi-12, uhulumeni uzoqhubeka ukukhulisa ukwenziwa kwezingxenye zemishini esezingeni eliphezulu. Lapha sikhetha intuthuko eminingana ebalulekile ku- "Planction Plan" kanye nezimboni ze-Valve ezimele zokuhlaziywa okungenzeka kokungenisa indawo. Ukusuka ekuhlaziyweni, kungabonakala ukuthi kungenzeka ukuthi ukufakwa esikhundleni sokungenisa indawo yama-valves kuma-sub-mbombo ahlukahlukene kuyahluka kakhulu, futhi ama-valves aphezulu aphela adinga ukuholwa yinqubomgomo okuthe xaxa kanye nokwesekwa kocwaningo lwesayensi.
Imboni ye-valve idlala indima ebaluleke kakhulu njengesixhumanisi esibalulekile emkhakheni wokukhiqiza imishini ekuthuthukiseni umnotho wezwe. Kusukela izinga lemboni ye-Valedve yezwe lasekhaya lezwe lami liseyibanga elithile kude nezinga eliphakeme lamazwe omhlaba, ukhiye abaningiamavalveNgamapharamitha aphezulu, izinga lokushisa eliphakeme kanye nengcindezi ephezulu, futhi izinga eliphakeme lamaphawundi belihlala lithembele ekungeniseni. Isibonelo, uhlobo lwe-European Omal belulokhu kungukukhethwa okuyinhloko kwemboni yohlelo lokusebenza lwe-valve yasekhaya. Ukuze kukhuthaze ukwenziwa kwendawo ama-valves, ngemuva kokuthi uMkhandlu Wombuso ukhiphe "imibono eminingana ngokusheshisa ukuvuselelwa komkhakha wokwakha imishini", iminyango efanele yombuso yenze uchungechunge lokuthunyelwa okukhulu ngokuya ngezidingo zokwenziwa kwemishini emikhulu. I-LED yiKhomishini Yezokuthuthukiswa Kwezwe kanye Nezinguquko, imishini yaseChina Imboni Federation kanye ne-China General Machch Mitachnical Association bathumele futhi bakha aisivalwanaUhlelo lokwenziwa kwasendaweni lwemishini emikhulu emikhakheni ehlobene, futhi luhlanganiswe neminyango efanele izikhathi eziningi. Manje ukwenziwa kwasendaweni kwama-valves kwakha ukuvumelana embonini yeValve yasekhaya. Basebenzise ngenkuthalo amazinga aphesheya komklamo womkhiqizo; bamba izakhiwo ezihle kakhulu zokwakhiwa okuhle (kufaka phakathi ubuchwepheshe obunelungelo lobunikazi); Ukuhlolwa komkhiqizo nokuhlola ukusebenza kwenziwa ngokuqinile ngokuya ngamazinga aphesheya; Umuzwa wenqubo yokukhiqiza yakwamanye amazwe futhi unamathisele ukubaluleka ocwaningweni nasekukhulisweni kwezinto ezintsha; Cacisa amapharamitha wezobuchwepheshe kanye nezimo zokusebenza ze-Valve Valve Valve engenisiwe, njll. Ziyizindlela zokusheshisa inqubo yokwenziwa kwasendaweni, zikhuthaze ukuqhubeka kokuvuselelwa kwemikhiqizo ye-valve, bese ubona ngokuphelele ukwenziwa kwendawo kwama-valve. Ngokusheshisa kwejubane lokuhlelwa kabusha embonini ye-valve, imboni yesikhathi esizayo izoba ngumncintiswano phakathi kwekhwalithi yomkhiqizo we-valve kanye nokuphepha kanye nemikhiqizo yomkhiqizo. Imikhiqizo izokhula ngokuqondisa kobuchwepheshe obuphakeme, amapharamitha aphezulu, ukumelana okuqinile kokugqwala, kanye nokuphila okude. Ngobuchwepheshe obuqhubekayo ubuchwepheshe obuqhubekayo, ukuthuthukiswa kwemikhiqizo emisha, kanye nenguquko yezobuchwepheshe Cabanga kancane kancane izinga lezobuchwepheshe lomkhiqizo lithuthuke kancane kancane ukuze kufinyelelwe kudivayisi yasekhaya futhi kubona kahle ukwenziwa kwendawo kwama-valve. Ngaphansi kwendawo enkulu yesidingo, imboni ye-valve yezwe lami izokhombisa amathuba okuthuthuka okungcono.
