Ububi bevalvu yebhabhathane yerabha ukuthi uma isetshenziselwa ukubhoboza, ukubhoboza kuzokwenzeka ngenxa yokusetshenziswa okungafanele, okubangela ukuthi isihlalo serabha siqhekeke futhi sonakale. Ngenxa yalesi sizathu, amavalvu ebhabhathane avaliwe ngensimbi athuthukiswe emhlabeni wonke, kanti indawo yokubhoboza inciphile. Eminyakeni yamuva nje, izwe lami lithuthukise namavalvu ebhabhathane avaliwe ngensimbi. EJapane, amavalvu ebhabhathane amise okwekamu anokumelana nokubhoboza, ukudlidliza okuphansi nomsindo ophansi nawo athuthukiswe eminyakeni yamuva nje.
Ngokuvamile, isikhathi sokuphila sesihlalo sokuvala ivalvu yebhabhathane siyiminyaka eyi-15-20 yerabha kanye neminyaka engama-80-90 yensimbi ngaphansi kwezimo ezijwayelekile. Kodwa-ke, ukukhetha okulungile kuncike ezidingweni zezimo zokusebenza.
Ubudlelwano phakathi kwezinga lokuvula levalvu yebhathane yokuvala insimbi kanye nezinga lokugeleza lishintsha ngokuyisisekelo. Uma isetshenziselwa ukulawula ukugeleza, izici zayo zokugeleza nazo zihlobene kakhulu nokumelana nokugeleza kwamapayipi. Isibonelo, kufakwa amapayipi amabili anobubanzi bevalvu obufanayo kanye nesimo, kodwa i-coefficient yokulahlekelwa yipayipi ihlukile, futhi izinga lokugeleza kwevalvu nalo lizohluka kakhulu. Uma ivalvu isesimweni esinobubanzi obukhulu be-throttle, ingemuva lepuleti levalvu lithambekele ekuqhekekeni, okungalimaza ivalvu. Ngokuvamile, isetshenziswa ngaphandle kwama-15°.
Uma ukulungiswa kwe-butterfly seal yensimbi kusesikhaleni esiphakathi, isimo sokuvula esakhiwe ngumzimba we-valve kanye nengxenye engaphambili ye-butterfly plate sigxile ku-valve shaft, futhi izinhlangothi ezimbili zakhiwa ukuze kuqedwe izimo ezahlukene. Ingxenye engaphambili ye-butterfly plate ohlangothini olulodwa ihamba iye ohlangothini lwamanzi agelezayo, kanti olunye uhlangothi lugeleza emuva. Ngakho-ke, uhlangothi olulodwa lomzimba we-valve kanye ne-valve plate kwakha ukuvulwa okufana nomlomo, kanti olunye uhlangothi lufana nokuvulwa kwe-throttle. Uhlangothi lwe-nozzle lunesivinini sokugeleza esisheshayo kakhulu kunohlangothi lwe-throttle, futhi i-valve eseceleni ye-throttle izokhiqiza i-Pressure engemihle, izivalo zerabha zivame ukuwa.
I-torque yokusebenza yokulungiswa kwe-butterfly seal yensimbi inamanani ahlukene ngenxa yezindlela ezahlukene zokuvula nokuvala kwe-valve. I-valve butterfly evundlile, ikakhulukazi i-valve butterfly enobubanzi obukhulu, ngenxa yokujula kwamanzi, i-torque ekhiqizwa umehluko phakathi kwamakhanda amanzi aphezulu nangaphansi e-valve shaft ayinakunakwa. Ngaphezu kwalokho, lapho kufakwa indololwane ohlangothini lokungena lwe-valve, kwakheka ukugeleza kwe-bias futhi i-torque izokwanda. Lapho i-valve isendaweni ephakathi nendawo, indlela yokusebenza idinga ukuzikhiya ngenxa yesenzo se-torque yokugeleza kwamanzi.

INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
