Kufanele siyikhethe njani i-flange butterfly valve?

I-flange butterfly valveisetjenziswa khulu emaphayiphini wokukhiqiza wezebubulo, indima yayo ekulu kukusika ukujikeleza kwe-medium ephayiphini, nofana ukulungisa ubukhulu bokugeleza kwe-medium ephayiphini. I-flange butterfly valve isetjenziswa khulu ebunjiniyeleni bokulondolozwa kwamanzi, ukuhlanza amanzi, i-petroleum, ibubulo lamakhemikhali, ukufuthumala emadorobheni namanye amabubulo jikelele, begodu ingasetjenziswa naku-condenser kanye ne-cooling water system yesiteshi samandla womtjhiso.
I-flanged butterfly valve ilungele khulu ukwenza i-valve enkulu, esetjenziswa khulu emkhakheni wokulawula ububanzi obukhulu. Lokha i-flange butterfly valve nayivulwa ngokuzeleko, ukujamelana nokugeleza kuncani. Lokha i-Angle yokuvula iphakathi kwama-15-70, i-flange butterfly valve ingaba buthakathaka khulu ukulawula ukugeleza kwe-medium.
Ukungezelela, ngombana ipuleti yevithamini ye-flange butterfly valve iyasulwa lokha nayijikelezako, umhlobo lo we-valve ungasetjenziswa emaphayiphini ane-suspended granular medium, begodu ngokuya ngamandla we-seal, ungasetjenziswa godu emigqeni ye-powder ne-granular ye-medium.

Ukuhlukaniswa kwamavalvu we-butterfly ane-flanged
I-flanged butterfly valve ingahlukaniswa ibe yi-soft sealing flange butterfly valve kanye ne-hard sealing flange butterfly valve ngokuya ngezinto zokuvala.
Into yokuvala ye-soft seal flange butterfly valve yirabha neplastiki ye-fluorine; begodu into yokuvala ye-hard seal flange butterfly valve yinsimbi ukuya ensimbini, insimbi ukuya epulasitiki ye-fluorine kanye nepuleti ehlanganisiweko enamalayini amanengi.
Indandatho yokuvala ye-soft seal flange butterfly valve ingafakwa ngaphakathi kwe-valve body channel begodu ingafakwa eduze ne-butterfly plate. Lokha nayisetjenziswa njenge-cut off valve, ukusebenza kwayo kokuvala kungafikelela ku-FCI 70-2:2006 (ASME B16 104) VI, ephezulu khulu kunaleyo ye-hard seal flange butterfly valve. Kodwana, ngebanga lokuthi izinto ezithambileko zokuvala zikhawulelwa mazinga womtjhiso, i-valve ye-flange yokuvala ethambileko ivamise ukusetjenziswa emkhakheni wokulondolozwa kwamanzi nokuhlanza amanzi emazingeni womtjhiso wegumbi.

I-valve ye-butterfly flange yensimbi eqinileko ineenzuzo zezinto eziphathekako, ingatjhugulukela emazingeni womtjhiso aphezulu wokusebenza, umfutho omkhulu wokusebenza, ipilo yomsebenzi yinde ukudlula i-soft seal, kodwana ubumbi be-hard seal flange butterfly valve busobala, kubudisi ukuyenza ivalwe ngokupheleleko, ukusebenza kokuvala kumbi khulu, njeke umhlobo lo we-valve kodwana ngokuvamileko usetjenziselwa ukusebenza kokuvala ingasi phezulu, yenza ukulungisa ukugeleza.
