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 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 butterfly valve body for -29 ° C -+180 ° C, umzimba we-WCB butterfly valve ≤425 ° C, umzimba we-Stainless Steel butterfly valve ≤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.
Ngenxa yalezi zici ezingenhla, i-centerline butterfly valve ilungele ukusetshenziswa emanzini ahlanzekile, indle, amanzi olwandle, amanzi anosawoti, umusi, igesi yemvelo, ukudla, imithi, imikhiqizo ye-petroleum, ukuvulwa okuphindwe kabili nokuvalwa kwamapayipi okungenisa umoya nokukhipha uthuli, kanye nama-acids ahlukahlukene ngokujwayelekile, 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 uvemvane evalwe kanzima ifanele izimo ezinokushisa okuphezulu, umfutho ophezulu 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.
