Iivalvu yebhabhathaneyasungulwa e-United States ngawo-1930. Yalethwa eJapan ngawo-1950 futhi yayingasetshenziswa kabanzi eJapan kwaze kwaba ngawo-1960. Ayizange ithandwe ezweni lakithi kwaze kwaba ngawo-1970. Izici eziyinhloko zamavalvu e-butterfly yilezi: i-torque encane yokusebenza, isikhala esincane sokufaka kanye nesisindo esincane. Uma sithatha i-DN1000 njengesibonelo,ivalvu yebhabhathanecishe i-2T, kuyilaphoivalvu yesangocishe ingama-3.5T.ivalvu yebhabhathaneKulula ukuhlanganisa namadivayisi ahlukahlukene okushayela futhi inokuqina okuhle nokuthembeka. Ububi bama-valve e-butterfly avaliwe ngerabha ukuthi uma esetshenziselwa ukugoqa, ukugoqa kuzokwenzeka ngenxa yokusetshenziswa okungafanele, okubangela ukuthi isihlalo serabha siqhekeke futhi sonakale. Ngakho-ke, indlela yokuyikhetha kahle incike ezimweni zokusebenza. Ubudlelwano phakathi kokuvulwa kwe-valve ye-butterfly kanye nesilinganiso sokugeleza buqondile. Uma isetshenziselwa ukulawula izinga lokugeleza, izici zayo zokugeleza nazo zihlobene eduze nokumelana nokugeleza kwamapayipi. Isibonelo, uma i-valve caliber kanye nesimo samapayipi amabili kufana, kodwa i-coefficient yokulahlekelwa yipayipi ihlukile, izinga lokugeleza kwe-valve nalo lizohluka kakhulu. Uma i-valve isesimweni sokuphakama okukhulu kokugoqa, ukugoqa kungenzeka ngemuva kwepuleti le-valve, okungalimaza i-valve. Ngokuvamile isetshenziswa ngaphandle kwama-15°. Laphoivalvu yebhabhathaneingaphakathi komgodi ophakathi, isimo sokuvuleka esakhiwe ngumzimba wevalvu kanti ingxenye engaphambili yepuleti levemvane igxile emgodleni wevalvu, futhi kwakheka izimo ezahlukene ezinhlangothini zombili. Ingxenye engaphambili yepuleti levemvane ohlangothini olulodwa ihamba iye ohlangothini lokugeleza kwamanzi, kanti olunye uhlangothi luhamba iye ohlangothini lokugeleza kwamanzi. Ngakho-ke, umzimba wevalvu kanye nepuleti levalvu ohlangothini olulodwa kwakha umgodi omise okwe-nozzle, kanti olunye uhlangothi lufana nomgodi omise okwe-throttle. Uhlangothi lwe-nozzle lunesivinini sokugeleza esisheshayo kakhulu kunohlangothi lwe-throttle, futhi ingcindezi engemihle izokhiqizwa ngaphansi kwevalvu ohlangothini lwe-throttle, futhi uphawu lwerabha luvame ukuwa. I-torque yokusebenza yeivalvu yebhabhathaneiyahlukahluka ngenxa yezimbobo ezahlukene kanye nezinkomba zokuvula nokuvala kwevalvu. I-torque ekhiqizwa umehluko phakathi kwamakhanda amanzi aphezulu nangaphansi evalvu yebhabhathane evundlile, ikakhulukazi ivalvu enobubanzi obukhulu, ngenxa yokujula kwamanzi, ayinakunakwa. Ngaphezu kwalokho, lapho indololwane ifakwa ohlangothini lokungena lwevalvu, kwakheka ukugeleza kwe-bias, futhi i-torque izokwanda. Uma ivalvu isendaweni ephakathi nendawo, indlela yokusebenza idinga ukuzikhiya ngenxa yesenzo se-torque yokugeleza kwamanzi.
IShayina inezinqwaba zezimboni zama-valve, kodwa akuyona amandla e-valve. Ngokuvamile, izwe lami selingene ezinhlwini zamandla e-valve emhlabeni, kodwa maqondana nekhwalithi yomkhiqizo, izwe lami lisakude kakhulu nokuba amandla e-valve. Imboni isenokugxila okuphansi kokukhiqiza, amakhono aphansi e-R&D ama-valve ahambisana nemikhiqizo ephezulu, kanye nezinga eliphansi lobuchwepheshe bokukhiqiza embonini yama-valve, kanye nokuntuleka kokuhweba ngokungenisa nokuthumela kwamanye amazwe kuyaqhubeka nokukhula. Azikho nhlobo izinkampani zama-valve eziningi ezingasinda emakethe. Kodwa-ke, lokhu kushaqeka okusheshayo embonini yama-valve kuzoletha amathuba amakhulu, futhi umphumela wokushaqeka uzokwenza ukusebenza kwemakethe kube okunengqondo kakhudlwana. Indlela eya endaweni yama-valve aphezulu "inzima kakhulu". Izingxenye eziyisisekelo sezibe ukushiyeka okuvimbela intuthuko yemboni yokukhiqiza yezwe lami ibe ngephezulu. Ngesikhathi sohlelo lweminyaka emihlanu lwe-12, uhulumeni uzoqhubeka nokwandisa indawo yezingxenye zemishini ephezulu. Lapha sikhetha intuthuko eminingana ebalulekile "kuHlelo Lokusebenza" kanye nezimboni zama-valve ezimele ukuhlaziywa kokungenzeka kokushintshaniswa kokungenisa kwamanye amazwe. Kusukela ekuhlaziyweni, kungabonakala ukuthi ukukwazi ukufaka esikhundleni ama-valve kwamanye amazwe ezimbonini ezincane ezahlukahlukene kuyahlukahluka kakhulu, futhi ama-valve aphezulu adinga ngokushesha isiqondiso senqubomgomo esengeziwe kanye nokusekelwa kocwaningo lwesayensi.
Imboni yama-valve idlala indima ebaluleke kakhulu njengesixhumanisi esibalulekile embonini yokukhiqiza imishini ekuthuthukisweni komnotho wezwe. Njengoba izinga lemboni yokukhiqiza ama-valve yasekhaya yezwe lami lisekude kakhulu nezinga elithuthukile lamazwe ngamazwe, eziningi ezibalulekileamavalvungemingcele ephezulu, izinga lokushisa eliphezulu kanye nomfutho ophezulu, kanye nezinga eliphezulu le-pound bekulokhu kuncike ekungenisweni kwempahla. Isibonelo, uphawu lwe-OMAL lwaseYurophu belulokhu luyindlela eyinhloko yokukhetha imboni yesicelo sama-valve yasekhaya. Ukuze kukhuthazwe ukwenziwa kwama-valve endaweni, ngemuva kokuba uMkhandlu Kahulumeni ukhiphe "Imibono Eminingana Ngokusheshisa Ukuvuselelwa Kwemboni Yokukhiqiza Imishini", iminyango kahulumeni efanele yenze uchungechunge lokufakwa okukhulu ngokuhambisana nezidingo zombuso zokwenziwa kwemishini emikhulu endaweni. Iholwa yiKhomishini Yentuthuko Kazwelonke kanye Nokuguqulwa, i-China Machinery Industry Federation kanye ne-China General Machinery Industry Association basebenzise futhi bakha i-ivalvuUhlelo lokwakha indawo lwemishini emikhulu emikhakheni ehlobene, futhi seluxhumanisene neminyango efanele izikhathi eziningi. Manje ukwakhiwa kwama-valve kwakha ukuvumelana embonini yama-valve yasekhaya. Ukwamukela ngenkuthalo amazinga omhlaba wonke okuklama umkhiqizo; ukumunca izakhiwo zokuklama ezinhle kakhulu zakwamanye amazwe (kufaka phakathi ubuchwepheshe obunelungelo lobunikazi); ukuhlolwa komkhiqizo kanye nokuhlolwa kokusebenza kwenziwa ngokuqinile ngokuhambisana nezindinganiso zomhlaba wonke; ukumunca ulwazi lwenqubo yokukhiqiza kwamanye amazwe futhi kufaka ukubaluleka ocwaningweni nasekukhuthazeni izinto ezintsha; ukucacisa amapharamitha obuchwepheshe kanye nezimo zokusebenza zemikhiqizo yama-valve ephezulu engenisiwe, njll. kuyizindlela zokusheshisa inqubo yokwakhiwa kwendawo, ukukhuthaza ukuvuselelwa okuqhubekayo kwemikhiqizo yama-valve, kanye nokuqaphela ngokugcwele ukwakheka kwama-valve. Ngokusheshisa kwejubane lokuhlelwa kabusha embonini yama-valve, imboni yesikhathi esizayo izoba nomncintiswano phakathi kwekhwalithi yomkhiqizo wama-valve kanye nokuphepha kanye nemikhiqizo yomkhiqizo. Imikhiqizo izothuthuka ibheke ubuchwepheshe obuphezulu, amapharamitha aphezulu, ukumelana nokugqwala okunamandla, kanye nokuphila isikhathi eside. Kuphela ngokusungula ubuchwepheshe okuqhubekayo, ukuthuthukiswa kwemikhiqizo emisha, kanye nokuguqulwa kobuchwepheshe lapho izinga lobuchwepheshe bomkhiqizo lingathuthukiswa kancane kancane ukuze kuhlangatshezwane nokuqhathaniswa kwedivayisi yasekhaya futhi kuqashelwe ngokugcwele ukwakheka kwama-valve. Ngaphansi kwesimo sokufunwa okukhulu, imboni yokukhiqiza ama-valve yezwe lami ngokuqinisekile izobonisa amathuba angcono okuthuthukiswa.
