Xana hi fanele hi yi hlawula njhani valve ya phaphatani ra flange?

Valve ya phaphatani ra flangeyitirhisiwa ngopfu eka phayiphi ya vuhumelerisi bya ti indasitiri, ntirho wa yona lowukulu iku tsema ku rhendzeleka ka medium eka phayiphi, kumbe ku lulamisa vukulu bya ku khuluka ka medium eka phayiphi. Flange butterfly valve yitirhisiwa ngopfu eka vuinjhiniyere byo hlayisa mati, ku basisiwa ka mati, petroliyamu, indasitiri ya tikhemikhali, ku kufumeta madoroba na ti indasitiri tin’wana to angarhela, naswona yinga tlhela yitirhisiwa eka condenser na sisiteme ya mati yo kufumeta ya xitichi xa gezi ro hisa.
Flanged butterfly valve yi lulamerile ngopfu ku endla valve ya diameter leyikulu, leyi tirhisiwaka ngopfu eka ntirho wa vulawuri bya diameter leyikulu. Loko flange butterfly valve yi pfuriwile hiku hetiseka, ku tiya ka flow i kutsongo. Loko Angle yo pfuleka yiri exikarhi ka kwalomu ka 15-70, flange butterfly valve yingava na vuxiyaxiya swinene ku lawula ku khuluka ka medium.
Ku engetela kwalano, hikuva butterfly plate ya flange butterfly valve yi sula loko yi rhendzeleka, muxaka lowu wa valve wunga tirhisiwa eka tiphayiphi letingana suspended granular medium, naswona kuya hi matimba ya seal, yinga tlhela yitirhisiwa eka powder na granular lines ya medium.

Ku hlawuriwa ka ti flanged butterfly valves
Flanged butterfly valve yinga avanyisiwa hi soft sealing flange butterfly valve na hard sealing flange butterfly valve kuya hi switirhisiwa swale henhla swa sealing.
Nchumu wo pfalela wa soft seal flange butterfly valve i rhaba na pulasitiki ya fluorine; naswona switirhisiwa swo pfalela swa hard seal flange butterfly valve i nsimbi kuya eka nsimbi, nsimbi kuya eka fluorine plastiki na multi-layer composite plate.
Ring yo pfalela ya soft seal flange butterfly valve yinga nghenisiwa eka valve body channel naswona yinga nghenisiwa ku rhendzela butterfly plate. Loko yitirhisiwa tani hi cut off valve, matirhelo ya yona yo pfalela yanga fika eka FCI 70-2:2006 (ASME B16 104) VI, yale henhla swinene kutlula ya hard seal flange butterfly valve. Kambe hikokwalaho ka leswi swilo swo olova swo pfalela swi pimiweke hi mahiselo, soft seal flange butterfly valve yitala kutirhisiwa eka ntirho wa nhlayiso wa mati xikan’we naku basisiwa ka mati eka mahiselo ya kamara.

Metal hard seal flange butterfly valve yina swipfuno swa swilo, yinga pfumelelana na mahiselo yale henhla yo tirha, ntshikelelo lowukulu wo tirha, vutomi bya vutirheli byi lehe kutlula soft seal, kambe ku pfumaleka ka hard seal flange butterfly valve swile rivaleni, swa tika ku swiendla swi pfaleriwile hiku hetiseka, matirhelo ya sealing ayi kahle swinene, hikokwalaho muxaka lowu wa flange butterfly valve hi ntolovelo yitirhisiwa eka xilaveko xa matirhelo ya sealing ayi le henhla, endla lulamisa ku khuluka.

Handle ka sweswo, Tianjin Tanggu Water Seal Valve Co., Ltd. i thekinoloji ya xiyimo xa le henhla ya elastic seat valve leyi seketelaka mabindzu, swikumiwa ielastic xitulu wafer phaphatani valve, lug valve ya phaphatani, double flange concentric valve ya phaphatani, flange yimbirhivalve ya phaphatani ya eccentric, valve yo ringanisela, valve yo kambela tipuleti timbirhi ta wafer, .Y-Xigwitsirisina swin’wana. Eka Tianjin Tanggu Water Seal Valve Co., Ltd., hi tinyungubyisa hi ku nyika switirhisiwa swa xiyimo xo sungula leswi fikelelaka swiyimo swa le henhla swa indasitiri. Hi nxaxamelo wa hina wo anama wa tivalvu na switirhisiwa, u nga hi tshemba ku nyika ntlhantlho lowu hetisekeke eka sisiteme ya wena ya mati. Tihlanganisi na hina namuntlha ku dyondza swo tala hi switirhisiwa swa hina na ndlela leyi hi nga ku pfunaka ha yona.
