Ngokusho kwefomu lokuxhumana le-flange, iumzimba we-butterfly valveihlukaniswe ikakhulukazi: uhlobo lwe-wafer A, uhlobo lwe-wafer LT, i-flange eyodwa, i-flange ephindwe kabili, i-flange yohlobo lwe-U.
I-wafer yohlobo A iwukuxhuma kwembobo okungeyona imicu, uhlobo lwe-LT 24" ngaphezu kokucaciswa okukhulu kuvame ukusebenzisa amandla angcono womzimba we-valve yohlobo lwe-U ukwenza uxhumano olucushiwe, isiphetho sepayipi sidinga ukusebenzisa uhlobo lwe-LT.
Ngokwesakhiwo sokubeka uphawu, iumzimba we-butterfly valveingahlukaniswa ngemizimba yerabha evuvukele (isihlalo esingabuyiseleki indawo), umzimba we-valve ehlukanisiwe (ngokuvamile onesihlalo esimelana nokugqwala), kanye nomzimba wesihlalo esingashintshwa (nesihlalo sangemuva esiqinile nesihlalo esithambile).
Izinto zomzimba wethu ezivame ukusetshenziswa kuma-valve ovemvane agxile ikakhulukazi: insimbi eyinsimbi, i-ductile iron, umzimba wensimbi ecijile, umzimba wensimbi engagqwali, umzimba wethusi owenziwe ngethusi, umzimba we-aluminium ophonsiwe kanye nomzimba wensimbi oyi-super duplex.
I-Cast iron: Into evame kakhulu ngaphakathi kwevalve uvemvane, esetshenziswa kakhulu ohlelweni lwamanzi, kulula ukugqwala, impilo yesevisi emfushane, eshibhile.
I-Cast iron: I-Cast iron ifanele ingcindezi yegama elithi PN ≤ 1.0MPa, izinga lokushisa -10 ℃ ~ 200 ℃ lamanzi, umusi, umoya, igesi namafutha kanye neminye imidiya.Insimbi empunga esetshenziswa ngokujwayelekile izindinganiso namamaki yilawa: GB/T 12226, HT200, HT250, HT300, HT350.
I-Ductile iron: Ukusebenza kwe-valve uvemvane kuqhathaniswa nensimbi ye-carbon, ngokuvamile esetshenziswa epayipini lesistimu yamanzi, kodwa futhi okwamanje uhlelo lwamanzi ekusetshenzisweni kwezinhlobonhlobo ezibanzi kakhulu.
I-Ductile iron: Ifanele i-PN ≤ 2.5MPa, izinga lokushisa -30 ~ 350 ℃ amanzi, umusi, umoya namafutha kanye neminye imidiya.Izindinganiso ezivame ukusetshenziswa kanye namabanga: GB/T12227:2005 QT400-15, QT450-10, QT500-7;EN1563 EN-GJS-400-15,ASTM A536,65 45-12,ASTM A395,65 45 12.
Insimbi ye-Carbon: Ingasetshenziswa futhi ohlelweni lwamanzi, i-carbon steel butterfly valve inezinga lokushisa eliphezulu nokumelana nokucindezela, i-valve ye-butterfly eqinile evamile ene-carbon steel material.
Insimbi ye-Carbon: Ifanele ingcindezi yegama elithi PN ≤ 3.2MPa, izinga lokushisa -30 ~ 425 ℃ amanzi, umusi, umoya, i-hydrogen, i-ammonia, i-nitrogen nemikhiqizo ye-petroleum nokunye okuphakathi.Amamaki kanye namazinga asetshenziswa kakhulu yi-ASTM A216/216M: 2018WCA, WCB, ZG25 kanye nensimbi yekhwalithi ephezulu engu-20, 25, 30 kanye nensimbi ephansi ye-alloy 16MN.
Insimbi engagqwali: Amavalvu ovemvane ensimbi engagqwali anokugqwala okuhle kakhulu nokumelana nokugqwala, futhi asetshenziswa kakhulu kumapayipi adinga ukugqwala nokugqwala, futhi izindleko ziphezulu uma kuqhathaniswa.Isebenza ekucindezelweni okuzisholo kwe-PN ≤ 6.4.0MPa, izinga lokushisa: -268 ° C kuya ku-+425 ° C, ngokuvamile elisetshenziswa emanzini, emanzini olwandle, embonini yamakhemikhali, kawoyela negesi, imithi, indawo yokudla.Amazinga avamile namabanga: ASTM A351/351M:2018, SUS304,304, SUS316, 316
Ingxubevange yethusi: I-Copper alloy butterfly valve ifaneleka ku-PN ≤ 2.5MPa amanzi, amanzi olwandle, umoya-mpilo, uwoyela kanye nokunye okuphakathi, kanye nemithombo ye-steam ekushiseni kuka -40 ~ 250 ℃, amamaki asetshenziswa kakhulu ZGnSn10Zn2 (ithusi le-tin ), H62, Hpb59-1 (ithusi), QAZ19-2, QA19-4 (ithusi le-aluminium).Amazinga avamile namabanga: ASTM B148:2014, UNS C95400, UNS C95500, UNS C95800;I-ASTM B150 C6300.
