1. Nhlamuselo ya Masungulo na Xivumbeko
Valve ya maphaphatani ya soft sealing flanged concentric (leyi tivekaka tani hi "center-line butterfly valve") i quarter-turn rotary valve leyi endleriweke ku on/off kumbe throttling flow control eka tiphayiphi. Swihlawulekisi swa yona swa nkoka swi katsa:
Concentric Design: Nsinya wa valve, disc na xitulu swi ringanisiwile eka axis yin’we yale xikarhi, leswi endlaka leswaku kuva na xivumbeko xo olova no hlangana.
Soft Sealing Mechanism: Xisirhelelo xa elastomeric lexi olovaka (xikombiso, rhaba, EPDM, NBR) xihlanganisiwa eka miri wa valve kumbe xitulu, leswi nyikaka xisirhelelo xo tiya ku sivela ku vupfa.
Flanged Ends: Valve yi hlomisiwile hi swihlanganisi swa flanged, leswi pfumelelaka ku vekiwa hiku olova eka tiphayiphi leti landzelaka swipimelo swofana na ANSI, DIN, kumbe JIS.
2.Swiphemu swa Nkoka
3. Nsinya wa Nawu wa Ntirho
Open Position: Disiki yi rhendzeleka hi 90° ku fambisana na tlhelo ra ku khuluka, ku hunguta ku hunguteka ka ntshikelelo na ku pfumelela ku khuluka loku heleleke.
Xiyimo lexi Pfala: Disiki yi rhendzeleka yi tlhelela endzhaku leswaku yi tshikilela xisirhelelo xo olova, leswi endlaka leswaku ku va ni ku pfala loku tiyeke. Dizayini ya concentric yititshege hi elastic deformation ya seal kuva yi fikelela ku pfariwa, leswi endlaka leswaku yitirha swinene eka switirhisiwa swa ntshikelelo wale hansi.
4. Swihlawulekisi swa Nkoka na Swipfuno
Ku Pfala Ku Tiyile: Swisirhelelo swo olova swinyika ku tiya ka kahle swinene ka ku vupfa, leswi talaka ku fikelela swipimelo swa bubble-tight (xikombiso, ANSI B16.104 Class VI, ISO 15848-1).
Low Torque Operation: Dizayini ya concentric xikan’we na flexible seal swihunguta friction, leswi pfumelelaka ku tirha hi voko hiku olova kumbe kutirhisiwa na ti actuators to vevuka.
Compact and Lightweight: Loko yi pimanisiwa na ti gate kumbe globe valves, ti concentric butterfly valves i titsongo naswona swa olova ku ti veka eka tindzhawu letinga ringanelangiki.
Ku durha: Xivumbeko xo olova xikan’we na matirhiselo yale hansi ya switirhisiwa swiendla leswaku ti fikeleleka eka swilaveko swa xisekelo swa vulawuri bya ku khuluka.
Ku fambisana ka Media hi tindlela to tala: Swi lulamerile eka mati, moya, oyili, swilo leswi nga onhiki, na swihangalasamahungu swa granular (leswi nga na swifunengeto leswi nga tshovekiki).
5. Swihlawulekisi swa Xithekiniki
Mpimo wa Ntshikelelo: Hi ntolovelo ntshikelelo wale hansi kuya eka wa le xikarhi (xikombiso, PN6– .PN16 / Tlilasi ya 125– .Tlilasi ya 150).
Ndzhawu ya Mahiselo: .
Ti elastomers ta ntolovelo (xikombiso, NR, EPDM): -10°C ku ya eka 90°C (14.)°F ku ya eka 194°F).
Swisirhelelo swa mahiselo yale henhla (xikombiso, Viton®, PTFE): -20°C ku ya eka 150°C (-4.)°F ku ya eka 302°F).
Ku landzelerisa Swipimelo: .
Dizayini: EN593, API 609, MSS SP-67.
Xiphepherhele: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Ku kamberiwa: API 598, (swikambelo swa ku vupfa).
6. Swikombelo
Ku pfariwa ko olova ka flanged concentric butterfly valves D341X-16Qswi tirhisiwa ngopfu eka:
Mphakelo wa Mati na ku Humesiwa ka Mati: Tisisiteme ta mati ta masipala, tipulani to basisa thyaka, na tinetiweki to cheleta.
Tisisiteme ta HVAC: Ku lawula moya, mati kumbe mpfula eka ku kufumeta, ku nghenisa moya ni ku hunguta moya.
Vumaki bya Swakudya na Swakunwa: Switirhisiwa swa vuhlayiseki leswi nga na swisirhelelo leswi fambisanaka na FDA (xikombiso, EPDM leyi nga na swifunengeto swa giredi ya swakudya).
Maendlelo yo Angarhela ya Tiindasitiri: Ku khomiwa ka mati lawa yanga bola eka swimilani swa tikhemikhali, maphepha, na mirhi (eka swihangalasamahungu swo olova ntsena).
Ku Aka Lwandle na Swikepe: Vulawuri bya ku pfula/tima eka mati ya lwandle kumbe tisisiteme ta ballast (na switirhisiwa leswi nga onhiki).
7. Swipimelo na Swilo Leswi Langutisiwaka
Swipimelo swa Ntshikelelo na Mahiselo: Aswi ringanelanga eka switirhisiwa swa ntshikelelo wale henhla (xikombiso, >PN16) kumbe mahiselo yotala swinene (xikombiso, steam yale henhla ka 150°C).
Makhombo ya Ntshikelelo: Swiphemu swa nsimbi (xikombiso, mimiri ya nsimbi leyi hoxiweke) swinga bola eka tindzhawu letinga na matimba; ku ndlandlamuxa ku ya eka nsimbi leyi nga riki na swilo kumbe switirhisiwa leswi pfanganisiweke eka swiyimo swo tika.
Abrasive Media: Swisirhelelo swo olova swinga ambala hiku hatlisa na swihalaki leswinga tala swiphemuphemu; anakanya hi tivalvu ta maphaphatani leti pfaleriweke hi matimba kumbe swilo leswi engetelekeke leswi sirhelelaka.
Ku Hlawula Actuator: Eka ti valve ta diameter leyikulu kumbe ku tirha nkarhi na nkarhi, tirhisa ti pneumatic/hydraulic actuators ku papalata ku karhala hi mavoko.
8. Ku Vekiwa na ku Hlayisa
Ku vekiwa ka swilo:
Tiyisisa leswaku ti flanges ti ringanisiwile naswona ti bolts ti tiyisiwile hindlela yin’we ku sivela ku vupfa.
Papalata ku veka valve ehansi ka ntshikelelo lowukulu wa tiphayiphi.
Lunghisa:
Nkarhi na nkarhi kambela seal kuva yi onhaka kumbe ku pandzeka, ngopfu ngopfu eka switirhisiwa swa high-cycle.
Tota nsinya na actuator nkarhi na nkarhi ku tiyisisa leswaku switirha kahle.
Cinca xisirhelelo loko ku vupfa ku humelela; tipulani tin’wana ti pfumelela ku cinciwa ka seal handle ko susa valve eka phayiphi.
9. Switsundzuxo swa ku Hlawula Muphakeri na Swikumiwa
Xitifikheti xa Switirhisiwa: Tiyisisa leswaku ti seals ti fikelela swipimelo swa indasitiri (xikombiso, FDA eka swakudya, ATEX eka tindzhawu leti pfurhaka).
Swihlawulekisi swa ku Endliwa hi ku landza swilaveko swa wena: Vaphakeri van’wana va nyika tipulani leti lwisanaka na static, swihlawulekisi leswi hlayisekeke eka ndzilo, kumbe swifunengeto swo hlawuleka (xikombiso, epoxy, PTFE) eka switirhisiwa swa niche.
Mahetelelo
Ku pfariwa ko olova ka flanged concentric butterfly valvesi xitshunxo lexi nga durhiki, lexi tshembekaka xa vulawuri bya ku khuluka ka ntshikelelo wa le hansi ku ya eka wa le xikarhi eka switirhisiwa leswi nga riki swa nkoka. Ku olova ka tona, ku pfariwa ka tona swinene, na ku olova ka ku hlayisa swi endla leswaku ti va nhlawulo lowu dumeke eka mati, HVAC, na tisisiteme ta tiindasitiri hi ku angarhela. Eka tindzhawu leti lavaka ngopfu, ku ndlandlamuxa kuya eka ti eccentric designs kumbe switirhisiwa swa premium swa hlohleteriwa. Minkarhi hinkwayo kambela swivumbeko swa vuhangalasi bya mahungu, swiyimo swa ntirho, na swilaveko swa ku landzelela ku hlawula valve leyinene eka swilaveko swa wena.
Rhaba yin’wana na yin’wana leyi tshameke concentricvalve ya phaphatani, ku fana na valve ya phaphatani ra wafer, valve ya phaphatani ra lugD7L1X-16Q, Y-xisefo, valve yo kambela wafer, .valve ya gedeZ41X-16Qswilaveko, swi nga tihlanganisa naValve ya TWSfektri, hi ta ku hlamula ro sungula.
