I-Flange Lethambile Yekuvala Ivalvu Yeluvivane Lephindvwe kabili (Luhlobo Lweshafti Leyomile)

Incazelo Yemkhicito

Timphawu Letimcoka Tesakhiwo

1. Umklamo Lophindvwe kabili
   • I-Eccentricity Yekucala: Iivalvushaft i-offset kusuka emkhatsini we-disc, kunciphisa kukhuhlana ngesikhatsi sekuvula/kuvala kanye nekunciphisa kugcoka etindzaweni tekuvala.
   • Eccentricity yesibili: Le shaft iphindze isuswe kusuka emgceni wemaphayiphi, kwenta “umphumela we wedging” lokhutsata kusebenta kwekuvala njengoba le disc ivala.
   • Inzuzo: Iniketa kwetsembeka lokusetulu kwekuvala futsi kwelula imphilo yekusebenta uma kucatsaniswa nemiklamo le-single-eccentric noma lesemkhatsini.
2. Indlela Yekuvala Lethambile
   • Le valve isebentisa indandatho yekuvala lethambile (levame kwentiwa nge EPDM, NBR, noma PTFE) lefakwe emtimbeni we valve noma ku disc, kucinisekisa kuvalwa lokungangeni moya kanye nekuhambisana netindzaba letehlukahlukene (sib., emanti, emafutsa, emagesi, kanye netintfo letingahlasimuli).
   • Inzuzo: Emazinga laphansi ekuvuta (ahlangabetana nemazinga e-API 598 noma ISO 15848) kanye ne-torque lencane ledzingekako yekusebenta.
3. Kwakhiwa kweShafu Leyomile
   • Le shaft ivalwe ngekwehlukana nekugeleta kwetindzaba, kuvimbela kuchumana ngco neludzaka. Lokwakhiwa kucedza tindlela letingavuza ngeshaft futsi kunciphisa bungoti bekugcola, ikakhulukati etindzaweni letinelulaka.
   • Ingcenye Lebalulekile: Timphawu tesicu letisezingeni lelisetulu (sib., kupakisha kweluhlobo lwe V noma timphawu temshini) kucinisekisa kutsi kute kuvuza eceleni kweshaft.
4. Kuxhumana kweFlange
   • Yakhelwe ngetindlela tekusebentisana te-flange letijwayelekile (sib., ANSI, DIN, JIS) kute ifakwe kalula emaphayiphini. Le flanged design iniketa kusimama kwesakhiwo futsi yenta kube lula kugcinwa.

Umtsetfosisekelo wekusebenta

• Kuvulwa: Njengobe leshaft ijikeleta, ilokuphindvwe kabilidisc ihamba kusuka esimeni lesivaliwe, kancane kancane disengaging kusuka uphawu soft. Ema-offsets la-eccentric anciphisa kucindzeteleka kwekucala kwekutsintsana, kwenta kutsi kusebente kahle, kusebenta nge-torque lephansi.
• Kuvala: Le disc ijikeleta emuva, futsi le geometry lephindvwe kabili-eccentric idala sento sekuvala lesichubekako. Umphumela we wedging ukhulisa umfutfo wekutsintsana emkhatsini we disc kanye ne seal, kucinisekisa kuvalwa lokucinile.
• Caphela: Lendlela yekwakha yeshaft leyomile icinisekisa kutsi leshaft ihlala ingatsintseki ngekushisa kwetindzaba, kucindzeteleka, noma kugcola, kwenta ncono kwetsembeka jikelele.

Tincazelo tebuchwepheshe

• Kuhlantwa Kwemanti: Emanti ekunatsa, emanti langcolile, kanye netinhlelo tekukhipha imfucuza (kudzinga kuvalwa lokusetulu kwentela emazinga ekuhlanteka).
• Imboni Yemakhemikhali: Tintfo letigugile, ema esidi, kanye ne alkalis (ishaft leyomile ivikela ekuhlaselweni ngemakhemikhali).
• Tinhlelo te-HVAC: Emaphayiphi ekuphefumula kanye nekushisa (i-torque lephansi yekusebenta njalo).
• Petrochemical & Oil/Gas: Tindzaba letingahlasimuli njenge oyili, igesi, kanye netinhlayiya (kuvalwa lokutsembekile etinchubeni letibucayi).
• Kudla & Kunatsa: Kusebentisa kuhlanteka (timphawu letihambisana ne FDA ticinisekisa kuphepha kwemkhicito).

• Tinzuzo Ngetulu Kwemavalvu Esintfu

  • Kuvala Lokuphakeme: Tivalo letitsambile ticedza kuvuta, tilungele kusetjentiswa lokudzinga kuvikelwa kwemvelo noma kuhlanteka lokusetulu.
  • Kusebentisa Emandla: Kusebenta kwe-torque lephansi kunciphisa tidzingo temandla e-actuation, kwehlisa tindleko tekusebenta.
  • Kuphila sikhatsi lesidze: Umklamo we-Double-eccentric unciphisa kugcoka, kantsi leshaft leyomile ivikela ekugcobeni, kwelula imphilo yekusebenta.
  • Konga Sikhala: Sakhiwo lesincane uma sicatsaniswa nemavalvu esango noma emhlaba, silungele kufakwa kwesikhala lesincane.

  Tiluleko Tekunakekela Nekufaka

  • Kufakwa: Ciniseka kutsi emaflanges ahambisana futsi emabhawudi aciniswa ngekulingana kwentela kugwema kucindzeteleka emtimbeni wevalve.
  • Kugcinwa: Hlola njalo le soft seal kutsi ayigcoki yini bese uyayifaka esikhundleni uma ilimele. Gcobisa ishafti kanye ne-actuator ngetikhatsi letitsite kucinisekisa kusebenta kahle.
  • Kugcina: Gcina endzaweni leyomile, lete lutfuli nge valve levulekile kancane kwentela kucedza kucindzeteleka esivalweni.
  Le valve ihlanganisa bunjiniyela lobutfutfukile kanye nekuklama lokusebenta, kuniketa sisombululo lesetsembekile nalesingabizi setidzingo tekulawula kugeleta kwetimboni tesimanje. Kute wente ngekwemvelo lokutsite (sib., kutfutfukiswa kwetintfo noma kugcoba lokukhetsekile), sicela ubonane nemkhiciti.
