Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici
▪ Uhlobo oluhlezi lwensimbi eccentric kabili.
▪ Idizayini Yediski Elula.
▪ Umsebenzi wokuvala ama-bidirectional, ukufakwa akunqunyelwe ukugeleza kwe-medium.
 Insimbi engagqwali engazwani nokuvala impahla ukuze kuqinisekiswe impilo ende yesevisi.
 Isetshenziswa kakhulu ezimeni ezahlukene zokusebenza kanye nezinsizakusebenza.
▪ Ukusebenza kahle okuphezulu nokonga amandla nge-half shaft structure kanye ne-truss type disc.
 Ingasetshenziswa isikhathi eside emanzini kuvalvu enegiya.
▪ Indlela ehlukile yokubonisa ehambisanayo yevalve uvemvane evundlile efakwe ngaphansi.

▪ Hlola ingcindezi:
I-Shell Test Pressure 1.5 x PN
I-Seal Test Pressure 1.1 x PN

Ukuphepha Kuqinisekisiwe Ezimeni Zokusebenza Ezinzima
▪ Izidingo ezinzima kakhulu ziyadingeka ngosayizi omkhulu noma amavalvu omfutho ophezulu ezimeni zokusebenza ngokwedlulele.Ukuze kuxazululwe le nkinga, sithuthukise idizayini yasekuqaleni enezendlalelo ezimbili ngokusekelwe ku-topology.Lo mklamo we-skeleton mechanism wenza ukuthi i-disc ibe namandla aphezulu, angasetshenziselwa ukucindezela okuphezulu okudingekayo nezimo ezinkulu zobubanzi.Ngakolunye uhlangothi, ukugeleza kokugeleza kwesigaba sesiphambano kungakhuliswa ukuze kuncishiswe i-coefficient yokumelana nokugeleza.

Uku-oda Ulwazi
▪ Izinga lokushisa elihlukile lokusebenza ngenketho, sicela ucacise.
▪ Uhlobo olusetshenziswayo olujwayelekile kanye nohlobo oluvikela ukuqhuma kuyatholakala kumavalvu evemvane ehlezi ensimbi ane-actuator kagesi.
▪ Sicela ucacise uma kudingeka isibonisi esivumelanayo esinezinhlangothi ezimbili zamavalvu evemvane aqhutshwa ngegiya lezikelemu.
▪ Eminye imininingwane edingekayo iyatholakala, sicela usho uma ikhona.

Isimiso Sokusebenza
▪ I-worm gear esebenza ngezindlela ezimbili ze-butterfly valve yehliswa ngegiya le-worm gear kanye nezinye izindlela ngokuzungezisa isondo lesandla noma isikwele sesibambo sekhoni, futhi iqhube i-valve shaft ne-butterfly disc ukuze ijikeleze phakathi kwama-degree angu-90 ngokusebenzisa igiya lezikelemu. ukwehla, ukuze kufezwe inhloso yokusika, ukuxhuma noma ukulawula ukugeleza.I-valve uvemvane ovala uphawu olukabili kagesi yehliswa i-actuator kagesi ngegiya lezikelemu noma ishayela ngokuqondile i-valve shaft kanye ne-butterfly disc ukuze ijikeleze phakathi kwamadigri angu-90, ukuze kufezwe injongo yokuvula nokuvala ivalvu.
▪ Kungakhathaliseki ukuthi igiya lezikelemu noma imodi yokushayela kagesi, ivalvu evulekile noma evalekile inqunyelwe indlela elinganiselwe.Futhi indlela ekhombisayo ibonisa ngokulinganayo isimo sokuvula sediski uvemvane.

Isicelo
 Amavalvu emvemvane asetshenziswa kakhulu kunethiwekhi yokuphakelwa kwamanzi kamasipala, uhlelo lwamanzi okupholisa, ukusatshalaliswa kwamanzi, uhlelo lokuphehla ugesi ngamanzi, indawo yokuhlanza indle, iphrojekthi yokuphambukisa amanzi, embonini yamakhemikhali, ekuncibilikiseni amanzi kanye nezinye izinhlelo zokuphakelwa kwamanzi kanye nezinhlelo zokuphehla ugesi.Isebenza emanzini aluhlaza, emanzini ahlanzekile, igesi ebolayo, i-liquid and multiphase fluid medium, futhi inomthethonqubo, imisebenzi enqamuliwe noma engabuyisi.
▪ I-valve uvemvane ene-double eccentric structure iyasebenza ekuvaleni kwendlela eyodwa.Ngokuvamile, izofakwa ngendlela ephawuliwe.Uma isimo sokubeka uphawu sinezindlela ezimbili, sicela usibonise, noma usebenzise i-valve yohlobo lwevemvane enomugqa ophakathi nendawo.

Amanothi
▪ Imiklamo, izinto zokwakha kanye nokucaciswa okubonisiwe kungashintsha ngaphandle kwesaziso ngenxa yokuthuthukiswa okuqhubekayo kwemikhiqizo.
