Ivalve yebhabhathane ukuvula nokuvala icwecwe yipleyiti yebhabhathane emile okwediski, ejikeleza kwiaxis yayo kumzimba wevalve, ngaloo ndlela iphumeza ukuvulwa kunye nokuvala okanye ukulawulwa kwevalve kubizwa ngokuba yivalve yebhabhathane. Iivalve zebhabhathane zihlala zingaphantsi kwama-90 degrees zivuliwe kwaye zivaliwe. Iivalve zebhabhathane kunye neerodi zebhabhathane azinawo amandla okuzivalela. Ukuze kufunyanwe ipleyiti yebhabhathane, isinciphisi sezixhobo zeentshulube kufuneka sifakwe kwisiqu sevalvu. Ukusetyenziswa kwe-worm gear reducer ayikwazi nje ukwenza i-butterfly plate ibe namandla okuzivalela, yenza i-butterfly plate imise kuyo nayiphi na indawo, kodwa iphucula ukusebenza kwevalve.
Iivalvu zebhabhathane zeshishini ziphawulwa ngokumelana nobushushu obuphezulu, uluhlu loxinzelelo oluphezulu, idiameter enkulu yegama, umzimba we-carbon steel kunye nentsimbi yentsimbi endaweni yeringi yerabha. Ivalve yebhabhathane enkulu yobushushu obuphezulu idityaniswe ngepleyiti yentsimbi, isetyenziswa ikakhulu kumbhobho werhasi engumbhobho kunye nombhobho werhasi wobushushu obuphakathi. Ivalve yebhabhathane ephakathi Imodeli esebenzayo ineenzuzo zesakhiwo esilula kunye nokuveliswa okufanelekileyo. Ivalve yebhabhathane enerabha eqhelekileyo yeyolu hlobo.
Ukungalungi kukuba ipleyiti yebhabhathane kunye nesihlalo sevalve zihlala zikwimo ye-extrusion, i-scratch, umgama omkhulu wokuxhathisa kunye nokukhawuleza ukunxiba kunye nokukrazula. Ukuze kusonjululwe ingxaki ye-extrusion phakathi kwepleyiti yebhabhathane kunye nesihlalo sevalve yebhabhathane egxininisekileyo, kuveliswa ivalve yebhabhathane eccentric. Isici sayo sesakhiwo kukuba i-axis ye-stem iyaphambuka ukusuka kumbindi we-butterfly plate, ukwenzela ukuba isiphelo esisezantsi se-butterfly plate asisekho iziko lokujikeleza, kunye nokugqithisa okugqithisileyo phakathi kwesiphelo esisezantsi se-butterfly plate kunye ne-butterfly plate. isihlalo sincitshisiwe.
Ivalve yebhabhathane eneeccentric ephindwe kabini yeyona valve yebhabhathane eneeccentric esetyenziswa kakhulu, ethi iphuculwe ngakumbi ngesiseko sevalve yebhabhathane eneeccentric enye. Ulwakhiwo lubonisa ukuba i-axis yesikhondo sevalve iyatenxa kumbindi wepleyiti yebhabhathane kunye nombindi womzimba. Impembelelo ye-eccentricity ephindwe kabini yenza ukuba ipleyiti yebhabhathane ikhuphe kwisihlalo sevalve ngokukhawuleza emva kokuba ivalve ivuliwe, isusa kakhulu i-extrusion engaphezulu kunye nokukrwela phakathi kwepleyiti yebhabhathane kunye nesihlalo sevalve, ukunciphisa ukuchasana kokuvula, ukunciphisa ukunxiba kunye nokukrazula, kwaye ukuphucula ubomi benkonzo yesitulo sevalvu.
