Zvinoenderana neiyo flange yekubatanidza fomu, iyobutterfly vharafu muviriyakakamurwa zvakanyanya kuita: wafer mhando A, wafer mhando LT, imwe flange, kaviri flange, U mhando flange.
Wafer mhando A haina-shinda yegomba yekubatanidza, LT mhando 24" pamusoro peakakura mataurirwo anowanzo shandisa simba riri nani U-mhando vharafu muviri kuita threaded connection, kupera kwepombi inoda kushandisa LT mhando.
Maererano nechisimbiso chimiro, thebutterfly vharafu muviriinogona kupatsanurwa kuita rabha vulcanized body (isina-inotsiviwa chigaro muviri), inopatsanura vharafu muviri (kazhinji ine chigaro chinodzivirira ngura), uye chinotsiviwa chigaro chemuviri (nechakaoma kumashure chigaro uye chigaro chakapfava).
Zvishandiso zvemuviri wedu zvinowanzo shandiswa mumavharuvhu evhavhavha akanyanya: simbi yakakandwa, ductile iron, muviri wesimbi yakakandwa, muviri wesimbi isina tsvina, muviri wendarira wakakanda, muviri wealuminium wakakanda uye wakakanda super duplex simbi muviri.
Cast iron: Zvinhu zvinonyanya kuzivikanwa mukati mevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,dzinonyanya kushandiswa muhurongwa hwemvura,zviri nyore kuita ngura,hupenyu hupfupi hwebasa, zvakachipa.
Cast iron: Cast iron inokodzera kudzvinyirirwa nezita PN ≤ 1.0MPa, tembiricha -10 ℃ ~ 200 ℃ yemvura, chiutsi, mhepo, gasi uye mafuta uye mamwe midhiya.Grey cast iron zviyero uye mamakisi anowanzo shandiswa ndeaya: GB/T 12226, HT200, HT250, HT300, HT350.
Ductile iron: Mushavishavi vharuvhu kuita kunofananidzwa nekabhoni simbi chinhu, chinowanzo shandiswa mupombi yemvura system, asiwo parizvino hurongwa hwemvura pakushandiswa kwemhando dzakasiyana siyana.
Ductile iron: Inokodzera PN ≤ 2.5MPa, tembiricha -30 ~ 350 ℃ mvura, utsi, mhepo uye mafuta uye mamwe midhiya.Zvinowanzoshandiswa zviyero uye mamakisi ndeaya: GB/T12227:2005 QT400-15, QT450-10, QT500-7;EN1563 SH-GJS-400-15,ASTM A536,65 45-12,ASTM A395,65 45 12.
Carbon simbi: Inogonawo kushandiswa muhurongwa hwemvura, kabhoni simbi butterfly vharafu ine tembiricha yakakwira uye kumanikidza kuramba, general hard seal butterfly valve yakawanda ine kabhoni simbi zvinhu.
Carbon simbi: Inokodzera zita rekumanikidza PN ≤ 3.2MPa, tembiricha -30 ~ 425 ℃ mvura, chiutsi, mhepo, hydrogen, ammonia, nitrogen uye petroleum zvigadzirwa uye zvimwe zvepakati.Inowanzo shandiswa mamakisi uye zviyero ndeye ASTM A216/216M: 2018WCA, WCB, ZG25 uye yakakwirira mhando simbi 20, 25, 30 uye yakaderera alloy structural simbi 16MN.
Simbi isina Stainless: Simbi isina tsvina mavharuvhu ane ngura yakanaka kwazvo uye anodzivirira ngura, uye anoshandiswawo zvakanyanya mumapaipi anoda kukora uye kushora, uye mutengo wacho wakakwira.Inoshanda kune zita rekumanikidza PN ≤ 6.4.0MPa, tembiricha yemhando: -268 ° C kusvika +425 ° C, inowanzoshandiswa mumvura, mvura yegungwa, indasitiri yemakemikari, mafuta uye gasi, mushonga, chikafu chepakati.Zviyero zvakajairika uye mamakisi: ASTM A351/351M:2018, SUS304,304, SUS316, 316
Copper alloy: Copper alloy butterfly valve inokodzera PN ≤ 2.5MPa mvura, mvura yegungwa, okisijeni, mhepo, mafuta uye imwe svikiro, pamwe nemhepo inopfungaira pane tembiricha ye -40 ~ 250 ℃, inowanzoshandiswa mamakisi eZGnSn10Zn2 (tin bronze ), H62, Hpb59-1 (ndarira), QAZ19-2, QA19-4 (aluminium bronze).Zviyero zvakajairika uye mamakisi: ASTM B148: 2014, UNS C95400, UNS C95500, UNS C95800;ASTM B150 C6300.
