Ezweni eliyinkimbinkimbi lezinhlelo zamapayipi ezimboni, ukulawula ukugeleza okuthembekile kubaluleke kakhulu.I-Flanged Ball Valveivelele njengenye yezixazululo ezisetshenziswa kakhulu nezithembekile.
Iyini i-Flanged Ball Valve?
I-Flanged Ball Valveiyi-Ball Valve eneUkuphela kweFlangeUkuxhumana.
Luhlobo lwevalvu yokujika ngekota esebenzisa ibhola levalvu ukulawula ukugeleza koketshezi. Isici sayo esichazayo? Esikhundleni seziphetho ezifakwe imicu noma ezihlanganisiwe, ihlanganisaAma-Flangesendaweni yokungena kanye neyokuphuma. Lawa ma-flange anamathela ngqo kuma-flange afanayo epayipini, okwenza kube nokuxhumana okuqinile, okuqinisayo, futhi okulula ukukugcina. Lo mklamo wenza ama-valve ebhola a-flange abe afanele ukusetshenziswa okudingakalayo ezimbonini eziningi, kusukela emigqeni yomusi ocindezelayo ophezulu kuya ekucutshungulweni kwamakhemikhali aqothulayo.
Ukuqonda Ama-Flanged Ball Valve: Ama-Flanges nama-Ball Valve
Ukuze siqonde ngokugcwele i-flanged ball valve, ake sihlukanise izakhi zayo ezimbili eziyisisekelo:
Iyini i-Ball Valve:
Inhliziyo yayo isekelwe endinganisweniI-Ball Valveisimiso. Ibhola eliyindilinga elinembobo (imbobo) phakathi nendawo lijikeleza ama-degree angu-90 ngaphakathi komzimba wevalvu. Uma imbobo ihambisana nepayipi, ukugeleza akuvinjelwe (kuvulekile). Uma lijikeleziswa liqondile, ibhola eliqinile livimba ukugeleza ngokuphelele (livaliwe). Lo mklamo unikeza ukusebenza okusheshayo, ikhono elihle kakhulu lokuvala, kanye nokuvinjelwa okuncane kokugeleza uma livuliwe ngokugcwele (ikakhulukazi emiklamo yembobo egcwele).
Kuyini Ukuxhumeka Kwe-Flange End:
I-flange ye-valve iyindlela yokwakha lapho i-valve ixhunywe khona epayipini kusetshenziswa indlela yokuxhuma i-flange. Iyingxenye evamile yokuxhuma ekhishwayo ezinhlelweni zamapayipi ezimboni.
Incazelo Eyinhloko:
I-flange ye-valve iyisakhiwo esimise okwe-flange esenziwe ngomshini kuzo zombili izinhlangothi noma endaweni yokungena kanye nendawo yokukhipha yomzimba we-valve. Iboshelwa ku-flange yepayipi kusetshenziswa amabhawodi nama-gasket ukuze kufezwe ukuvalwa nokugeleza.
Iyingxenye yesigaba "sama-valve axhunywe nge-flange," kugcizelelwa indlela yokuxhuma kunohlobo lwe-valve (isb., ama-valve e-butterfly, ama-valve ebhola, ama-valve esango, njll., wonke angafakwa nge-flange).
Ama-Flanges ayizingqimba ezisicaba, ezifana nediski ezinochungechunge lwezimbobo zebholithi ezibholiwe nxazonke zomphetho wazo. Ku-valve yebhola e-flanged, lawa afakwa ngokuphonswa noma ashiselwe emaphethelweni omzimba we-valve. I-valve ifakwa ngokufaka i-gasket phakathi kwama-flanges ayo nama-flanges epayipi, bese kuqinisa ama-bolts nxazonke. Lokhu kudala ijoyinti eliqinile kakhulu, elingacindezelwa elinganqanyulwa kalula ukuze kulungiswe noma kushintshwe i-valve ngaphandle kokusika ipayipi. Izindinganiso ezivamile ze-flange zifaka phakathi i-ASME B16.5 (ANSI) kanye ne-ASME B16.47 (API).
