Ngokutsho kwefom yoqhagamshelwano lweflange, iivalufa butterfly umzimbayahlulwe ikakhulu: uhlobo lwe-wafer A, uhlobo lwe-wafer LT, i-flange enye, i-flange ephindwe kabini, i-U uhlobo lwe-flange.
Uhlobo lwe-Wafer A ludibaniso lomngxuma olungenamisonto, uhlobo lwe-LT 24" ngaphezu kweenkcukacha ezinkulu ngokuqhelekileyo zisebenzisa amandla angcono u-U-uhlobo lwevalvu yomzimba ukwenza uxhulumaniso olunentambo, isiphelo sombhobho kufuneka sisebenzise uhlobo lwe-LT.
Ngokutsho kwesakhiwo sokutywinwa, iivalufa butterfly umzimbainokwahlulwa ibe ngumzimba werabha ovulnekekileyo (umzimba wesitulo esingatshintshiyo), umzimba wevalve eyahlula-hlulwe (ubukhulu becala inesitulo esimelana nomhlwa), kunye nesitulo esinokutshintshwa (enesitulo sangasemva esilukhuni kunye nesitulo esithambileyo).
Izinto zomzimba wethu ezisetyenziswa ngokuqhelekileyo kwiivalvu zebhabhathane ikakhulu: intsimbi etyhidiweyo, intsimbi edityanisiweyo, umzimba wentsimbi, umzimba wentsimbi engenasici, umzimba wobhedu owenziweyo, umzimba we-aluminium ophosekileyo kunye nomzimba wentsimbi we-super duplex.
Intsimbi yokuphosa: Eyona nto ixhaphakileyo ngaphakathi kwevalve yebhabhathane, isetyenziswa ikakhulu kwinkqubo yamanzi, kulula ukugrunjwa, ubomi benkonzo obufutshane, itshiphu.
Intsimbi yokuphosa: Intsimbi yokuphosa ifanelekile kuxinzelelo lwe-PN ≤ 1.0MPa, ubushushu -10 ℃ ~ 200 ℃ yamanzi, umphunga, umoya, igesi kunye neoli kunye nezinye imidiya.Imigangatho yentsimbi engwevu esetyenziswa ngokuqhelekileyo kunye namabakala ngala: GB/T 12226, HT200, HT250, HT300, HT350.
Intsimbi yentsimbi: Kumsebenzi wevalve yebhabhathane ithelekiseka nentsimbi yekhabhoni into, esetyenziswa ngokubanzi kumbhobho wenkqubo yamanzi, kodwa okwangoku isixokelelwano samanzi ekusetyenzisweni koluhlu olubanzi kakhulu lwemathiriyeli.
Intsimbi ye-Ductile: Ifanelekile kwi-PN ≤ 2.5MPa, ubushushu -30 ~ 350 ℃ amanzi, umphunga, umoya kunye neoli kunye nezinye imidiya.Imigangatho esetyenziswa ngokuqhelekileyo kunye 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.
Intsimbi yeCarbon: Inokusetyenziswa kwakhona kwinkqubo yamanzi, i-carbon steel butterfly valve inobushushu obuphezulu kunye nokumelana noxinzelelo, ivalve yebhabhathane yetywina ngokubanzi enzima ngakumbi nge-carbon steel material.
Intsimbi yeCarbon: Ifanelekile kuxinzelelo lwe-PN ≤ 3.2MPa, ubushushu -30 ~ 425 ℃ amanzi, umphunga, umoya, i-hydrogen, i-ammonia, i-nitrogen kunye neemveliso zepetroleum kunye nezinye izinto eziphakathi.Amanqanaba asetyenziswa ngokuqhelekileyo kunye nemigangatho yi-ASTM A216 / 216M: 2018WCA, WCB, ZG25 kunye nentsimbi ephezulu ye-20, 25, 30 kunye ne-alloy ephantsi ye-16MN yesakhiwo.
Intsimbi estainless: Iivalvu zebhabhathane zentsimbi zinerusa entle kakhulu kunye nokumelana nomhlwa, kwaye zikwasetyenziswa kakhulu kwimibhobho efuna ukugqwala nokuxhathisa umhlwa, kwaye ixabiso liphezulu ngokwentelekiso.Isebenza kwi-PN yoxinzelelo lwegama ≤ 6.4.0MPa, ububanzi bokushisa: -268 ° C ukuya ku-425 ° C, ngokuqhelekileyo kusetyenziswa emanzini, emanzini olwandle, imboni yeekhemikhali, ioli kunye negesi, iyeza, ukutya okuphakathi.Imigangatho eqhelekileyo kunye namabanga: ASTM A351/351M:2018, SUS304,304, SUS316, 316
Ingxubevange yobhedu: Copper ingxubevange butterfly valve ifanelekile PN ≤ 2.5MPa amanzi, amanzi olwandle, ioksijini, umoya, ioli kunye nezinye medium, kunye nemidiya umphunga kwiqondo lobushushu -40 ~ 250 ℃, amabanga asetyenziswa ngokuqhelekileyo ZGnSn10Zn2 (tin ubhedu ), H62, Hpb59-1 (ubhedu), QAZ19-2, QA19-4 (i-aluminium ubhedu).Imigangatho eqhelekileyo kunye namabanga: ASTM B148: 2014, UNS C95400, UNS C95500, UNS C95800;I-ASTM B150 C6300.
