Umehluko phakathi kwevalve uvemvane oluqinile kanye nevalve uvemvane uphawu

Izigxivizo eziqinile zenziwe ngensimbi, njengama-gaskets ensimbi, izindandatho zensimbi, njll., futhi ukuvalwa kutholakala ngokungqubuzana phakathi kwezinsimbi.Ngakho-ke, ukusebenza kokuvalwa kuphansi, kodwa ivalvu yethu ye-ZFA eyakhiwe nge-multi-layer hard seal triple offset butterfly valve ingafinyelela ukuvuza okungu-zero.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 e-butterfly eccentric kabili, kuyilapho ama-valve uvemvane ophawu oluqinile amavavu ovemvane ane-eccentric eyodwa 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 butterfly valve body for -29°C -+180°C, i-WCB butterfly valve body ≤425°C, i-Stainless Steel butterfly valve body ≤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: Ivalve uvemvane oluthambile uphawu kanye nevalve uvemvane oqinile we-offset offset asebenza kangcono kakhulu.I-valve yevemvane eyi-eccentric ephindwe kathathu ingagcina uphawu oluhle lokuvuza elinguziro lapho kunengcindezi ephezulu 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.Kungcono ukumiselela ama-valve esango nama-globe valves.
