Kunezinhlobo eziningi zei-butterfly valve discngokuya ngokusetshenziswa kwama-valve ovemvane, osayizi abavame kakhulu be-butterfly valve esitokisini basuka ku-DN50-DN600, ngakho-ke sizokwethula ama-valve discs ngokuya ngosayizi osetshenziswa njalo.
1.Inayiloni Coated Valve Disc
Ukufafaza inayiloni kuwubuchwepheshe obuvamile bokumboza indawo engaphezulu obufafaza izinhlayiya zenayiloni eziwuketshezi endaweni engaphansi bese kwakha ifilimu enayiloni eqinile nehlala isikhathi eside ngemva kokuqina.Ukufakwa kwesifutho senayiloni kunokusetshenziswa okuningi nezimo zohlelo, nazi ezinye zezinto ezisetshenziswayo ezijwayelekile:
- Ukuvikeleka kokugqwala: Ukufakwa kwenayiloni kungasetshenziswa njengesivikelo esingaphezulu sensimbi.Inayiloni inezici ezingcono zokunqanda ukubola, ingakwazi ukuhlukanisa insimbi ngokugeleza kwangaphandle, yelule ubude besikhathi se-valve disc.
- Yehlisa ukungqubuzana: Inayiloni inesici esingcono sokunciphisa ukungqubuzana, inganciphisa kalula ukungqubuzana phakathi kwesihlalo se-valve nediski.
- Ukumelana nokugqoka: Inayiloni inokusebenza okuhle kokungagugi, inganciphisa ukuklwebheka kwendawo yediski.
2.I-PTFE Lining Valve Disc
- Ayinamatheli: I-Surface ye-PTFE disc iyashelela kakhulu futhi ayinamathele, inganciphisa ngokuphawulekayo okunamathelayo kuzithiyo eziphakathi nendawo.
- Ukumelana nokugqwala: I-PTFE inokusebenza okuhle kokuqeda ukugqwala, yabiza iNkosi yepulasitiki ngenxa yezici zayo ezingavamile zokuqeda ukugqwala, ingakwazi ukumelana nemithombo eminingi ye-asidi eqinile ne-alkali.
- I-Chemical inertness: I-PTFE ukungabi nalutho kwezinto eziningi zamakhemikhali.Ingakwazi ukumelana nokugqwala kwamakhemikhali amaningi.
- Ukungagqoki: Nakuba i-PTFE iyimpahla ethambile, kodwa inokusebenza okuhle okungagugi uma kuqhathaniswa namanye amapulasitiki ngisho nensimbi.I-disc ene-PTFE surface izoba nesikhathi eside ngenxa yesici sayo.
3.I-Aluminium Bronze Valve Disc
Ithusi le-aluminium ingxubevange yethusi ngokuvamile iqukethe i-aluminium, ithusi nezinye izakhi ze-alloying ezifana ne-manganese, insimbi ne-zinc.Inezinzuzo eziningi ezenza isetshenziswe kabanzi ezinhlelweni ezahlukahlukene.
- Ukumelana nokugqwala okuhle: Ithusi le-aluminium linokumelana nokugqwala okuhle kakhulu, ikakhulukazi emanzini olwandle namanzi anosawoti.Lokhu kuyenza ibe yinto esetshenziswa kaningi ezinhlelweni zobunjiniyela zasolwandle nasogwini ezifana nama-propeller emikhumbi, ama-valve namapayipi.
4.Nickel Plate Butterfly Valve Disc
- Izici ezivimbela ukugqwala: Ipuleti le-nickel lingavikela ingaphezulu le-ductile iron disc kusukela ekugqwaleni emithonjeni yokusebenza.
- Ukuqina: Ngepuleti le-nickel, ingaphezulu le-DI disc lingaba lukhuni kunangaphambili.Ingasiza ukumelana ne-disc kuzithiyo ezimaphakathi zokusebenza.
5.I-Rubber Lining Valve Disc
- Ukusebenza kahle kokuvala: I-disc ene-raber lining izoba nokusebenza okuhle kakhulu kokuvala uma kuqhathaniswa nediski yensimbi, izohlinzeka ngezici ezithembekile zokuvala.Isiza i-valve ivimbele ukuvuza.
6.IDiski yeValve ye-Butterfly Esezingeni Eligelezayo
- Idizayini ekhethekile ye-disc yezinga lokugeleza okuphezulu inikeza ukusebenza okuhle kakhulu okugelezayo.Ngokuvumelana ne-shafe yayo ekhethekile nobukhulu obunembile, izokwehlisa ukumelana nokwehla kwengcindezi yemidiya esebenzayo, ifinyelele izinga lokugeleza eliphezulu.
