Butterfly valve yitirhisiwa ngopfu eka ku akiwa ka madoroba, petrochemical, metallurgy, gezi na ti indasitiri tin’wana eka phayiphi yale xikarhi ku endla ku tsema kumbe ku lulamisa ku khuluka ka xitirhisiwa xa kahle swinene. Xivumbeko xa valve ya phaphatani hi xoxe i swiphemu leswinene ngopfu swo pfula na ku pfala eka phayiphi, i nkongomiso wa nhluvukiso wa swiphemu swa namuntlha swo pfula na ku pfala tiphayiphi. Hi ntolovelo hi va na center line soft seal butterfly valve, leyi tirhisiwaka ngopfu eka mahiselo ya ntolovelo, swiyimo swa ntirho swa ntshikelelo wa le hansi, ku fana na mphakelo wa mati na ku humesa mati, tiphurojeke to hlayisa mati, ku akiwa ka masipala na tinsimu tin’wana. Leswi landzelaka ngopfu ngopfu switivisa switirhisiwa swa valve ya phaphatani ya eccentric yin’we, valve ya phaphatani ra double eccentric na valve ya phaphatani ra triple eccentric.
Xo sungula, xivumbeko xin’we xa eccentric xasoft seal valve ya phaphatani, ku pfalela xitulu xiphemu xo tsemakanya kumbe ku enta ka pulati ya phaphatani ya tlhelo ra layini leyi nga ekule hi ku ringana na le xikarhi ka ku rhendzeleka ka nsinya wa valve relative eccentric, leswaku valve ya phaphatani eka endlelo ro pfula, vuandlalo byo pfalela pulati ya phaphatani hakatsongo-tsongo ekule na vuandlalo byo pfalela xitulu xa valve. Ku rhendzeleka ka butterfly plate kuya eka 20 ~ 25 °, butterfly plate sealing surface yi hambanisiwile hiku hetiseka kusuka eka valve seat sealing surface, leswaku valve ya phaphatani eka maendlelo yo pfula, relative mechanical wear na extrusion exikarhi ka swiphemu swimbirhi swo sealing swihungutiwile swinene, leswaku matirhelo ya butterfly valve sealing yanga antswisiwa. Dizayini leyi ngopfu ngopfu yi titshege hi elastic deformation leyi endliwaka hi extrusion exikarhi ka butterfly plate na xitulu xa valve ku tiyisisa ku pfariwa ka butterfly valve.
Eka xisekelo xa valve yin’we ya phaphatani ya eccentric, xikarhi lexi rhendzelekaka xa butterfly plate xi offset kusuka eka layini yale xikarhi ya ndlela yo khuluka ya valve, leswi endlaka leswaku valve ya phaphatani yi vumba cam effect hinkarhi wa maendlelo yo pfula, leswaku vuandlalo byo pfalela bya butterfly plate byinga hambanisiwa kusuka eka vuandlalo byo pfalela bya xitulu xa valve hiku hatlisa kutlula xivumbeko xin’we xa eccentric. Loko butterfly plate yi rhendzeleka kuya eka 8°~12°, ndzhawu yo pfalela ya butterfly plate yi hambanisiwile hiku hetiseka na ndzhawu yo pfalela ya xitulu xa valve. Dizayini ya xivumbeko lexi yi hunguta swinene ku onhaka ka michini loku ringanaka na ku onhaka ka extrusion exikarhi ka swiphemu swimbirhi swo pfalela, leswi antswisaka matirhelo yo pfalela ya valve ya phaphatani.
Naswona hi ku ya hivalve ya phaphatani ra double eccentric, layini ya le xikarhi ya vuandlalo byo pfalela xitulu yi vumba eccentricity ya angular na layini ya le xikarhi ya valve, leswi endlaka leswaku vuandlalo byo pfalela bya pulati ya phaphatani byi hatla byi hambana na vuandlalo byo pfalela xitulu hi nkarhi wa ku pfula hi nkarhi wa ku pfuriwa ka pulati ya phaphatani, naswona ntsena ku khumbana na ku tshikelela vuandlalo byo pfalela xitulu hi nkarhi wa ku pfala. Nkatsakanyo lowu wo hlawuleka wa eccentricity wu tirhisa hiku hetiseka cam effect, wu herisa hiku hetiseka ku hlangana ka michini na abrasion exikarhi ka swiphemu swimbirhi swo pfalela swa butterfly valve sealing vice loko valve yi pfula naku pfala, naswona yi susa ku koteka ka abrasion na ku vupfa. Xisirhelelo lexi humesiweke xi cinciwile xi va xisirhelelo xa torque, naswona ku lulamisiwa ka ntshikelelo wa ku pfariwa ku endliwa hi ku lulamisa torque yo chayela ya le handle, leswaku matirhelo ya ku pfalela na vutomi bya vutirheli bya valve ya phaphatani leyi pfaleriweke ya swivumbeko swinharhu swa eccentric swi antswisiwa swinene.
Handle ka sweswo, Tianjin Tanggu Water Seal Valve Co., Ltd. i thekinoloji ya xiyimo xa le henhla ya rhaba leyi tshameke yi tshama valve leyi seketelaka mabindzu, swikumiwa swi tiyisela xitulu xa wafer phaphatani valve, lug phaphatani valve, double flange concentric phaphatani valve, balance valve, wafer dual plate check valve,Valve yo Humesa Moya, Y-Strainer na 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.
