I-valve yevemvane eyi-eccentric kathathu
I-offset yokuqala ukuthi i-valve shaft ingemuva kwe-disc shaft ukuze uphawu luvale ngokuphelele sonke isihlalo se-valve.
I-offset yesibili iwukuthi umugqa omaphakathi we-valve shaft ususiwe emgqeni wepayipi kanye nesikhungo se-valve ukugwema ukuphazamiseka ekuvuleni nasekuvaleni kwe-valve.
I-offset yesithathu iwukuthi i-axis ye-cone yesihlalo iphuma emgqeni ophakathi nendawo we-valve shaft, eqeda ukungqubuzana ngesikhathi sokuvala nokuvula futhi ifinyelele uphawu lokucindezela okufanayo eduze nesihlalo sonke.
Ama-valve evemvane kathathu anikeza izinzuzo ezimbalwa uma kuqhathaniswa namanye ama-valve avame ukusetshenziswa ezinhlelweni eziningi zomfula:
1.Ngokwezimo ezinzima zezinhlelo zokusebenza ezibucayi, ukuhlukaniswa kwe-steam kanye nokushisa okweqile, ama-valve e-butterfly ama-triple offset ahlinzeka ngokuthembeka nokusebenza nekhwalithi.
2.Ukuvalwa kokuvuza kwe-bi-directional uziro ngesihlalo sensimbi, ngisho nangemva kokuhamba ngebhayisikili okude, kunikeza ubuqotho bokuvala obebuhlotshaniswa kuphela namavalvu ahlezi kahle.
3.I-torque ephansi evela esenzweni sokujika kwekota ivumela ama-actuator amancane kanye nezindleko eziphansi.
4.Ivalve yevemvane ephindwe kathathu iphephile ngokwemvelo ngokuzungezisa okungahlikihliki kanye nemiklamo ehlolwe umlilo nge-API 607 ngayinye.
I-5.Ukwakheka kwayo okuhlangene kwenza ukufakwa kube lula njengoba ama-valve alula futhi adinga ukugxilwa kwamapayipi okuncane.
6.Amavalvu evemvane e-Triple offset anganikeza ukuncipha kwesisindo nesikhala kanye nokonga kwezindleko ezinkulu.
Amavalvu evemvane e-triple offset asetshenziswa lapho kudingeka khona isihlalo sensimbi, ukuvalwa okuqinile kanye ne-quarter turn actuation kuyadingeka. Okulandelayo ezinye izimboni lapho kusetshenziswa khona amavalvu evemvane amathathu: Uwoyela Negesi, Amandla Namandla, Ukuhlanza Amanzi Namanzi Angcolile,Amakhemikhali, Ukudla Neziphuzo,Ezemithi Nokunakekelwa Kwezempilo,Izinsimbi Nezimayini,Isakhiwo Nokwakha,Iphepha Nogaxa...
