Ivalve Yevavemvane Ethambile Ekabili Eccentric (Uhlobo Lweshaft Elomile)

Incazelo Yomkhiqizo

Izici Eziyinhloko Zesakhiwo

1. I-Double Eccentric Design
   • I-Eccentricity yokuqala: Ii-valvei-shaft isusiwe phakathi nendawo yediski, inciphisa ukungqubuzana ngesikhathi sokuvula/ukuvalwa nokunciphisa ukuguga ezindaweni zokuvala.
   • I-Eccentricity Yesibili: I-shaft iphinde isuswe emgqeni omaphakathi wepayipi, okwenza "umphumela wokushada" othuthukisa ukusebenza kokuvala njengoba idiski ivala.
   • Inzuzo: Ihlinzeka ngokuthembeka kokutywinwa okuphezulu futhi inwebe impilo yesevisi ngokuqhathaniswa nemiklamo ye-eccentric eyodwa noma egxile.
2. I-Soft Seal Mechanism
   • Ivalvu isebenzisa indandatho yokuvala ethambile (ngokujwayelekile eyenziwe nge-EPDM, NBR, noma PTFE) eshumekwe emzimbeni wevalvu noma idiski, iqinisekisa ukuvala komoya nokuhambisana nemidiya ehlukahlukene (isb, amanzi, uwoyela, amagesi, noketshezi olungabhubhi).
   • Inzuzo: Amazinga aphansi okuvuza (okuhlangabezana ne-API 598 noma amazinga e-ISO 15848) kanye ne-torque encane edingekayo ukuze usebenze.
3. Ukwakhiwa kwe-Dry Shaft
   • I-shaft ivalwe ngokuhlukana nokugeleza kwemidiya, ivimbela ukuthintana okuqondile noketshezi. Lo mklamo uqeda izindlela zokuvuza ezingase zibe khona ku-shaft futhi unciphisa izingozi zokugqwala, ikakhulukazi ezindaweni ezinolaka.
   • Ingxenye Ebalulekile: Izigxivizo zekhwalithi ephezulu (isb, ukupakishwa kohlobo lwe-V noma izigxivizo zemishini) ziqinisekisa ukuthi akuvuzi lutho eduze kwe-shaft.
4. Ukuxhumana kwe-Flange
   • Idizayinelwe ngezisetshenziswa ezijwayelekile ze-flange (isb, i-ANSI, i-DIN, i-JIS) ukuze zifakwe kalula kumapayipi. Idizayini ene-flanged inikeza ukuzinza kwesakhiwo futhi yenza ukulungiswa kube lula.

Isimiso Sokusebenza

• Ukuvula: Njengoba i-shaft ijikeleza, i-i-double-eccentrici-disc isuka endaweni evaliwe, kancane kancane ihlukane nophawu oluthambile. Ama-eccentric offsets anciphisa ukucindezelwa kokuxhumana kwasekuqaleni, okwenza kube lula, ukusebenza kwetorque ephansi.
• Ukuvala: I-disc izungeza emuva, futhi i-double-eccentric geometry idala isenzo sokuvala esiqhubekayo. Umphumela wokushada ukhulisa ingcindezi yokuxhumana phakathi kwe-disc ne-seal, iqinisekisa ukuvala okuqinile.
• Qaphela: Idizayini ye-shaft eyomile iqinisekisa ukuthi i-shaft ihlala ingathinteki izinga lokushisa lemidiya, ingcindezi, noma ukugqwala, okuthuthukisa ukwethembeka kukonke.

Imininingwane Yezobuchwepheshe

• Ukwelapha Amanzi: Amanzi okuphuza, amanzi angcolile, nezinhlelo zokukhucululwa kwendle (kudinga ukuvalwa uphawu okuphezulu kwezindinganiso zokuhlanzeka).
• Imboni Yamakhemikhali: Uketshezi olubolayo, ama-asidi, nama-alkali (i-shaft eyomile ivikela ekuhlaselweni kwamakhemikhali).
• HVAC Systems: Air conditioning kanye namapayipi okushisa (torque ephansi ukusebenza njalo).
• I-Petrochemical & Amafutha/Igesi: Imidiya engagayi njengowoyela, igesi, nezinyibilikisi (ukuvalwa okuthembekile ezinqubweni ezibucayi).
• Ukudla Nesiphuzo: Izicelo zenhlanzeko (izigxivizo ezithobela i-FDA ziqinisekisa ukuphepha komkhiqizo).

• Izinzuzo Ngamavalvu Endabuko

  • Ukuvalwa Okuphezulu: Izimpawu ezithambile zisusa ukuvuza, zilungele izinhlelo zokusebenza ezidinga ukuvikelwa kwemvelo noma ukuhlanzeka okuphezulu.
  • Ukusebenza kahle kwamandla: Ukusebenza kwetorque ephansi kunciphisa izidingo zamandla okusebenza, kwehlisa izindleko zokusebenza.
  • Ubude bokuphila: Idizayini ene-eccentric kabili inciphisa ukuguga, kuyilapho i-shaft eyomile ivikela ekugqwaleni, inwebe impilo yesevisi.
  • Ukonga Isikhala: Isakhiwo esiqinile uma siqhathaniswa nesango noma amavalvu embulunga, alungele ukufakwa kwesikhala esilinganiselwe.

  Amathiphu Okulungisa Nokufaka

  • Ukufakwa: Qinisekisa ukuthi ama-flange aqondile futhi ama-bolt aqiniswa ngokulinganayo ukugwema ukucindezeleka emzimbeni we-valve.
  • Ukunakekela: Hlola njalo isigxivizo esithambile ukuthi asigugile bese usishintsha uma sonakele. Gcoba i-shaft ne-actuator ngezikhathi ezithile ukuze uqinisekise ukusebenza kahle.
  • Isitoreji: Gcina endaweni eyomile, engenalo uthuli nevalvu evuleke kancane ukuze unciphise ukucindezeleka ocingweni.
  Le valve ihlanganisa ubunjiniyela obuthuthukisiwe nomklamo osebenzayo, ohlinzeka ngesixazululo esithembekile nesingabizi kakhulu sezidingo zesimanje zokulawula ukugeleza kwezimboni. Ukuze wenze ngokwezifiso ezithile (isb, ukuthuthukiswa kwempahla noma okokuhlanganisa okukhethekile), sicela uthintane nomkhiqizi.
