Ngokwefomu yoqhagamshelo lweflange,umzimba wevalvu yebhabhathaneYahlulwe ngokubanzi yaba: uhlobo lwe-wafer A, uhlobo lwe-wafer LT, i-single flange, i-double flange, i-U type flange.
Uhlobo lwe-wafer A luqhagamshelo lwemingxunya olungenamisonto, uhlobo lwe-LT olungaphezulu kwama-24" ludla ngokusebenzisa umzimba wevalvu yohlobo lwe-U onamandla angcono ukwenza uqhagamshelo olunemisonto, ekupheleni kombhobho kufuneka kusetyenziswe uhlobo lwe-LT.
Ngokwesakhiwo sokutywina,umzimba wevalvu yebhabhathaneinokwahlulwa ibe ngumzimba ngerabha ovundisiweyo (umzimba wesihlalo ongatshintshwayo), umzimba wevalvu owahlulweyo (ngokuvamile onesihlalo esingamelani nokugqwala), kunye nomzimba wesihlalo onokutshintshwa (onesihlalo esiqinileyo esingasemva kunye nesihlalo esithambileyo).
Izixhobo zomzimba ezisetyenziswa kakhulu kwiivalvu zebhabhathane ezixineneyo zezi: isinyithi esitshisiweyo, isinyithi esithambileyo, umzimba wentsimbi ephosiweyo, umzimba wentsimbi engatyiwayo, umzimba wobhedu ophosiweyo, umzimba we-aluminium ophosiweyo kunye nomzimba wentsimbi ephosiweyo ene-super duplex.
Isinyithi esityhidiweyo: Eyona nto ixhaphakileyo ngaphakathi kwevalvu yebhabhathane, esetyenziswa kakhulu kwinkqubo yamanzi, kulula ukuyilahla, ixesha layo lifutshane, kwaye ingabizi kakhulu.
Isinyithi esixonxiweyo: Isinyithi esixonxiweyo sifanelekile kuxinzelelo oluqhelekileyo lwe-PN ≤ 1.0MPa, ubushushu -10 ℃ ~ 200 ℃ bamanzi, umphunga, umoya, igesi kunye neoyile kunye nezinye izinto. Imigangatho kunye namanqanaba asetyenziswa rhoqo yi: GB/T 12226, HT200, HT250, HT300, HT350.
Intsimbi ethambileyo: Kwivalvu yebhabhathane, ukusebenza kwayo kufana nentsimbi yekhabhoni, esetyenziswa ngokubanzi kwimibhobho yenkqubo yamanzi, kodwa okwangoku ikwasetyenziswa kuluhlu olubanzi kakhulu lwezinto.
I-Ductile iron: Ifanelekile kwi-PN ≤ 2.5MPa, ubushushu -30 ~ 350 ℃ amanzi, umphunga, umoya kunye neoyile kunye nezinye izinto ezisetyenziswa rhoqo. Imigangatho kunye neeklasi ezisetyenziswa rhoqo zezi: 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 yekhabhoni: Ingasetyenziswa nakwinkqubo yamanzi, ivalvu yebhabhathane yentsimbi yekhabhoni inobushushu obuphezulu kunye nokumelana noxinzelelo, ivalvu yebhabhathane eqinileyo ngokubanzi inezinto zentsimbi yekhabhoni.
Intsimbi yekhabhoni: Ifanelekile kuxinzelelo oluqhelekileyo lwe-PN ≤ 3.2MPa, ubushushu -30 ~ 425 ℃ amanzi, umphunga, umoya, ihydrogen, i-ammonia, i-nitrogen kunye neemveliso zepetroleum kunye nezinye izinto ezisetyenziswa rhoqo. Amanqanaba kunye nemigangatho esetyenziswa rhoqo yi-ASTM A216/216M:2018WCA, i-WCB, i-ZG25 kunye nentsimbi yomgangatho ophezulu eyi-20, 25, 30 kunye nentsimbi yesakhiwo engaphantsi kwe-16MN.
Intsimbi engagqwaliyo: Iivalvu zebhabhathane zentsimbi engagqwaliyo zinokumelana okuhle kakhulu nokugqwala nokubola, kwaye zisetyenziswa kakhulu kwiipayipi ezifuna ukumelana nokugqwala nokugqwala, kwaye ixabiso liphezulu. Isebenza kuxinzelelo oluqhelekileyo lwe-PN ≤ 6.4.0MPa, uluhlu lobushushu: -268 ° C ukuya ku +425 ° C, idla ngokusetyenziswa emanzini, emanzini olwandle, kushishino lweekhemikhali, kwioyile nakwigesi, kumayeza, kwisixhobo sokutya. Imigangatho eqhelekileyo kunye namanqanaba: ASTM A351/351M:2018, SUS304,304, SUS316, 316
I-Copper alloy: I-Copper alloy butterfly valve ifanelekile kwi-PN ≤ 2.5MPa amanzi, amanzi olwandle, i-oksijini, umoya, ioyile kunye nezinye izinto, kunye ne-steam media kubushushu obuyi--40 ~ 250 ℃, ii-grades ezisetyenziswa rhoqo kwi-ZGnSn10Zn2 (i-tin bronze), i-H62, i-Hpb59-1 (i-brass), i-QAZ19-2, i-QA19-4 (i-aluminium bronze). Imigangatho kunye nee-grades ezifanayo: ASTM B148:2014, i-UNS C95400, i-UNS C95500, i-UNS C95800; i-ASTM B150 C6300.
