I-Soft Seal Butterfly Valve
I-Hard Seal Butterfly Valve
Izigxivizo eziqinile zenziwe ngensimbi, njengama-gaskets ensimbi, izindandatho zensimbi, njll., futhi ukuvalwa kutholakala ngokungqubuzana phakathi kwezinsimbi.Ngakho-ke, ukusebenza kokubekwa uphawu kubi kakhulu, kepha ivalvu yethu yeZFA yenziwemulti-layer hard seal triple eccentric butterfly valveingafinyelela ku-zero ukuvuza.Izigxivizo ezithambile zenziwe ngezinto ezinwebekayo, njengenjoloba, i-PTFE, njll. Kwezinye izinto ezinokushisa okuphezulu nokucindezela okukhulu, ezingakwazi ukuhlangabezana nezidingo zenqubo, ama-butterfly valves avalwe kanzima angakwazi ukuxazulula inkinga.
Umehluko phakathi kwamavalve uvemvane avalwe kanzima namavalve uvemvane avalwe ngokuthambile:
1. Umehluko wesakhiwo: Amavalvu ovemvane ophawu oluthambile ngokuvamile amavalve uvemvane aphakathi nendawo futhiama-valve evemvane eccentric kabili, kuyilapho ama-valve uvemvane ophawu oluqinile amavavu evemvane eccentric awodwa futhiama-valve evemvane eccentric kathathu.
2. Ukumelana nezinga lokushisa: Uphawu oluthambile lusetshenziswa endaweni yokushisa evamile, Irabha -20℃~+120℃, PTFE -25℃~+150℃.Uphawu oluqinile lungasetshenziswa ekushiseni okuphansi, izinga lokushisa elivamile, izinga lokushisa eliphezulu nezinye izindawo, i-LCB ye -29 ° C -+ 180 ° C, i-WCB ≤425 ° C, i-Stainless Steel≤600 ° C.
3. Ukucindezela: Uphawu oluthambile ukucindezela okuphansi-ingcindezi evamile PN6-PN25, uphawu oluqinile lungasetshenziswa nasezimeni zengcindezi ephakathi nendawo njenge-PN40 nangaphezulu.
4. Ukusebenza kokuvala: I-valve uvemvane ophawu oluthambile kanye ne-triple eccentric hard seal butterfly valve banokusebenza okungcono kokuvala.KathathuI-valve ye-butterfly eccentricingagcina uphawu oluhle lokuvuza kwe-zero ekucindezelweni okuphezulu kanye nendawo yokushisa ephezulu.Kodwa-ke, kunzima ngamavalvu ovemvane ajwayelekile avalwe kanzima ukuthola ukuvuza okuyiziro.
5. Impilo yesevisi: Ama-valve uvemvane avala uphawu ngokuthambile ajwayele ukuguga futhi aguge, futhi impilo yawo yesevisi kulindeleke ukuthi ibe mfushane.Ama-valve evemvane avalwe kanzima anesikhathi eside sokusebenza.
Uma kubhekwa lezi zici ezingenhla, i-centerline butterfly valve ilungele ukusetshenziswa emanzini ahlanzekile, indle, amanzi olwandle, amanzi anosawoti, umusi, igesi yemvelo, ukudla, imithi, imikhiqizo kaphethiloli, ukuvulwa okuphindwe kabili nokuvalwa kwamapayipi okungenisa umoya kanye nokukhipha uthuli, futhi ama-acids ahlukahlukene ekushiseni okuvamile, ingcindezi kanye nezimo zemidiya ezingagqwali.I-alkali namanye amapayipi adinga ukuvalwa okuphelele, ukuhlolwa kokuvuza kwegesi okuyiziro, kanye nezinga lokushisa elisebenzayo elingu -10~150℃.I-valve butterfly evalwe kanzima ifanele izimo ezinokushisa okuphezulu, ukucindezela okuphezulu kanye nemidiya edlayo, njengokulawula nokudonsa amapayipi kawoyela, igesi, i-asidi kanye ne-alkali njengokufudumeza kwedolobha, ukuhlinzekwa kwegesi, ukuhlinzekwa kwamanzi, i-petroleum, i-petrochemical, imboni yamakhemikhali, i-metallurgy, namandla kagesi.nezinye izinkambu.Iwukumiselela kahle ama-valve esango nama-globe valves.
