Imidiya esebenzayo: amanzi ahlanzekile, indle, amanzi olwandle, umoya, umusi, ukudla, imithi, amafutha ahlukahlukene, ama-acids, ama-alkali, usawoti, njll.

I-valve ye-butterfly ye-flange kagesi ivamise ukwakhiwa nge-angular stroke actuator (i-0-90 degree partial rotation) kanye ne-butterfly valve ngoxhumano lwemishini, ngemva kokufakwa nokulungisa iphutha.

Ipuleti uvemvane we valve uvemvane ifakwe ohlangothini ububanzi iphayiphi. Endleleni eyisilinda yomzimba wevalvu uvemvane, ipuleti le-butterfly lediski lizungeza i-eksisi, futhi i-engeli yokuzungezisa iphakathi kuka-0 ~90. Uma i-engeli yokuzungezisa iphakathi kuka-0 ~ 90, i-valve ivuleka ngokugcwele.

I-valve yevemvane ilula ngesakhiwo, incane ngevolumu futhi ilula ngesisindo, futhi iqukethe izingxenye ezimbalwa kuphela. I-valve ingavulwa futhi icishwe ngokushesha kuphela ngokuzungezisa amadigri angama-90. Ukusebenza kulula futhi i-valve inezici ezinhle zokulawula uketshezi.

Lapho i-valve ye-butterfly ye-flange isendaweni evulekile ngokugcwele, ukushuba kwepuleti levemvane kuwukuphela kokumelana lapho okuphakathi kugeleza emzimbeni we-valve, ngakho-ke ukwehla kokucindezela okukhiqizwa yi-valve kuncane kakhulu, ngakho kunezici zokulawula ukugeleza okungcono. I-Butterfly valve ine-elastic seal kanye ne-metal seal. I-valve yokuvala enwebekayo, indandatho yokuvala ingashumeka emzimbeni we-valve noma ixhunywe kupuleti lovemvane.

Amavalvu anezigxivizo zensimbi ngokuvamile anempilo ende yesevisi kunalawo anezigxivizo ezinwebekayo, kodwa kunzima ukufeza ukuvalwa okuphelele. I-Metal seal ingakwazi ukuzivumelanisa nezinga lokushisa eliphakeme lokusebenza, kanti uphawu olunwebekayo lunesici sokunciphisa izinga lokushisa.

Uma i-valve ye-butterfly idingeka ukuthi isetshenziswe njengokulawula ukugeleza, into esemqoka ukukhetha usayizi olungile kanye nohlobo lwe-valve. Isimiso se-butterfly valve sifaneleka ngokukhethekile ekwenzeni ama-valve amakhulu. Ama-valve e-Butterfly awasetshenziswa kakhulu kuphela ku-petroleum, igesi, imboni yamakhemikhali, ukwelashwa kwamanzi nezinye izimboni ezijwayelekile, kodwa futhi asetshenziswa ohlelweni lwamanzi okupholisa lwezitshalo zamandla ashisayo.

Amavalvu ovemvane asetshenziswa kakhulu amavalvu ovemvane namavalve uvemvane e-flange. I-valve ye-butterfly ye-clamp ixhunywe phakathi kwama-flange amapayipi amabili ngamabhawodi anamakhanda amabili. I-valve ye-butterfly ye-flange inama-flange ku-valve. Ama-flange emikhawulweni yomibili yevalvu axhunywe kuma-flange amapayipi ngamabholithi.

Esimeni esivuleke ngokugcwele, ukujiya kwepuleti levemvane kuwukuphela kokumelana lapho okuphakathi kugeleza emzimbeni we-valve, ngakho-ke ukwehla kokucindezela okukhiqizwa i-valve kuncane kakhulu.
