I-Soft Sealing Flange Double Eccentric Butterfly Valve (Uhlobo Lomshafu Owomile)

Incazelo Yomkhiqizo

Izici Eziyinhloko Zesakhiwo

1. Umklamo Ophindwe Kabili Ohlukile
   • Ubukhulu Bokuqala: Iivalvuumgodi ususwa phakathi nendawo yediski, okunciphisa ukungqubuzana ngesikhathi sokuvulwa/ukuvalwa futhi kunciphisa ukuguguleka ezindaweni zokuvala.
   • Ukulingana Kwesibili: I-shaft isuselwe kakhulu emgqeni ophakathi wepayipi, okudala "umphumela wokugoqa" othuthukisa ukusebenza kokuvala njengoba idiski ivala.
   • Inzuzo: Inikeza ukuthembeka okuphezulu kokuvala futhi yandisa impilo yesevisi uma kuqhathaniswa nemiklamo eyodwa noma eqondile.
2. Indlela Yokuvala Ethambile
   • Ivalvu isebenzisa indandatho yokuvala ethambile (evame ukwenziwa nge-EPDM, i-NBR, noma i-PTFE) efakwe emzimbeni wevalvu noma kwidiski, okuqinisekisa ukuvalwa komoya kanye nokuhambisana nemidiya ehlukahlukene (isb., amanzi, uwoyela, amagesi, kanye noketshezi olungagugi).
   • Inzuzo: Amazinga okuvuza aphansi (ahlangabezana nezindinganiso ze-API 598 noma ze-ISO 15848) kanye ne-torque encane edingekayo ukuze kusebenze.
3. Ukwakhiwa Komgodi Owomile
   • I-shaft ivalwe ngokwehlukana nokugeleza kwemidiya, okuvimbela ukuthintana ngqo noketshezi. Lo mklamo ususa izindlela ezingase zivuvuke ngo-shaft futhi unciphise izingozi zokugqwala, ikakhulukazi ezindaweni ezinolaka.
   • Ingxenye Eyinhloko: Izivalo zesiqu ezisezingeni eliphezulu (isb., ukupakisha kohlobo lwe-V noma izivalo zemishini) ziqinisekisa ukuthi akukho ukuvuza okuhambisana nomgodi.
4. Uxhumano lweFlange
   • Yakhelwe ngezixhumi ezijwayelekile ze-flange (isb., i-ANSI, i-DIN, i-JIS) ukuze kube lula ukufaka emapayipini. Idizayini ye-flange inikeza ukuzinza kwesakhiwo futhi yenza kube lula ukugcinwa.

Isimiso Sokusebenza

• Ukuvula: Njengoba umgodi ujikeleza,i-eccentric ephindwe kabiliidiski isuka endaweni evaliwe, isuka kancane kancane esivalweni esithambile. Ama-offsets angavamile anciphisa ukucindezeleka kokuqala kokuthintana, okwenza kube lula ukusebenza kahle, okune-torque ephansi.
• Ukuvala: Idiski ijikeleza emuva, futhi i-geometry ephindwe kabili idala isenzo sokuvala esiqhubekayo. Umphumela wokubopha wandisa ingcindezi yokuxhumana phakathi kwediski nesivalo, okuqinisekisa ukuvalwa okuqinile.
• Qaphela: Umklamo womshafti owomile uqinisekisa ukuthi umshafti uhlala ungathinteki izinga lokushisa lemidiya, ingcindezi, noma ukugqwala, okuthuthukisa ukuthembeka okuphelele.

Imininingwane Yobuchwepheshe

• Ukwelashwa Kwamanzi: Amanzi okuphuza, amanzi angcolile, kanye nezinhlelo zokulahla indle (kudinga ukuvalwa okuphezulu ukuze kutholakale amazinga okuhlanzeka).
• Imboni Yamakhemikhali: Uketshezi olubolayo, ama-asidi, nama-alkali (umgodi owomile uvikela ekuhlaselweni ngamakhemikhali).
• Izinhlelo ze-HVAC: Amapayipi omoya opholile kanye nokushisa (i-torque ephansi yokusebenza njalo).
• Amakhemikhali kaphethroli kanye namafutha/igesi: Izinto ezingasetshenziswa njenge-oyili, igesi, kanye nezinyibilikisi (ukuvalwa okuthembekile ezinqubweni ezibalulekile).
• Ukudla Neziphuzo: Ukusetshenziswa kwenhlanzeko (izivalo ezihambisana ne-FDA ziqinisekisa ukuphepha komkhiqizo).

• Izinzuzo Ngaphezu Kwama-Valve Endabuko

  • Ukuvalwa Okuphezulu: Izimbobo ezithambile zisusa ukuvuza, zifanele ukusetshenziswa okudinga ukuvikelwa kwemvelo noma ukuhlanzeka okuphezulu.
  • Ukusebenza Kahle Kwamandla: Ukusebenza kwe-torque ephansi kunciphisa izidingo zamandla okusebenza, kunciphisa izindleko zokusebenza.
  • Ubude Besikhathi: Idizayini enezici ezimbili inciphisa ukuguguleka, kuyilapho umgodi owomile uvikela ekugqwaleni, wandise isikhathi senkonzo.
  • Ukonga Isikhala: Isakhiwo esincane uma siqhathaniswa nama-valve esango noma eglobhu, silungele ukufakwa kwesikhala esilinganiselwe.

  Amathiphu Okulungisa Nokufaka

  • Ukufakwa: Qinisekisa ukuthi ama-flange aqondile futhi amabhawodi aqiniswe ngokulinganayo ukuze kugwenywe ukucindezeleka emzimbeni we-valve.
  • Ukulungisa: Hlola njalo isivalo esithambile ukuthi asigugi yini bese usishintsha uma sonakele. Gcoba umgodi kanye ne-actuator ngezikhathi ezithile ukuqinisekisa ukusebenza kahle.
  • Indawo Yokugcina: Gcina endaweni eyomile, engenalo uthuli nevalvu ivulekile kancane ukuze kuncishiswe ukucindezeleka esivalweni.
  Le valve ihlanganisa ubunjiniyela obuthuthukisiwe nomklamo osebenzayo, inikeza ikhambi elithembekile nelingabizi kakhulu lezidingo zesimanje zokulawula ukugeleza kwezimboni. Ukuze uthole ukwenza ngokwezifiso okuthile (isb., ukuthuthukiswa kwezinto noma ukumbozwa okukhethekile), sicela uxhumane nomkhiqizi.
