I-Soft Sealing Flange Double Eccentric Butterfly Valve (Dry Shaft Type)

Ihlathululo yomkhiqizo

Iimfanelo eziqakathekileko zesakhiwo

1. Idizayini engakajayeleki kabili
   • Ukutjhuguluka kokuthoma: Iivalvuishafti ihlukaniswe phakathi kwediski, ukwehlisa ukutjhayisana ngesikhathi sokuvula/ukuvala begodu kunciphisa ukuguga eendaweni zokuvala.
   • Ukutjhuguluka kwesibili: Ishafti iqaliswe phambili ukusuka emgqeni ophakathi wepayipi, okwenza "umphumela wokugoqa" othuthukisa ukusebenza kokuvala njengoba idiski ivala.
   • Inzuzo: Inikeza ukuthembeka okuphezulu kokuvala begodu kwandisa ipilo yomsebenzi nayiqathaniswa nemiklamo eyodwa-e-excentric nofana e-concentric.
2. Indlela yokuvala ethambileko
   • Ivalvu isebenzisa indandatho yokuvala ethambileko (evamise ukwenziwa nge-EPDM, NBR, nofana i-PTFE) efakwe emzimbeni wevalvu nofana idiski, ukuqinisekisa ukuvalwa okungenamoya nokuvumelana nemidiya ehlukahlukeneko (isib., amanzi, amafutha, amagesi, kanye noketshezi olungakhuhli).
   • Inzuzo: Amazinga aphasi wokuvuza (ahlangabezana namazinga we-API 598 nofana we-ISO 15848) kanye ne-torque encani etlhogekako ekusebenzeni.
3. Ukwakhiwa kweshafu eyomileko
   • Ishafu ivalwe ngokwehlukana nokugeleza kwemidiya, ukuvimbela ukuthintana ngqo ne-fluid. Umklamo lo uqeda iindlela zokuvuza ezingabakhona ngeshafti begodu wehlisa ubungozi bokugqwala, khulukhulu eendaweni ezinolaka.
   • Ingcenye eqakathekileko: Iimvalo zesiqu ezisezingeni eliphezulu (isib., ukupakisha okufana ne-V nofana iimvalo zomtjhini) ziqinisekisa bona akukho ukuvuza eceleni kweshafti.
4. Ukuxhumana kwe-flange
   • Yakhiwe ngeendlela ezijayelekileko (isib., i-ANSI, i-DIN, i-JIS) ukwenzela bona kube lula ukufakwa emapayipini. Umklamo one-flanged unikela ukuzinza kwesakhiwo begodu wenza kube lula ukutlhogonyelwa.

Umthethomgomo wokusebenza

• Ukuvulwa: Njengoba ishafu ijikeleza, ikabili-okungakajayelekiidiski isuka endaweni evaliweko, kancanikancani ihlukana nesivalo esithambileko. Ama-offset angakajayeleki anciphisa ukugandeleleka kokuthintana kokuthoma, okwenza bona kube nokusebenza okubushelelezi, okune-torque ephasi.
• Ukuvala: Idiski ijika emuva, begodu i-double-excentric geometry yenza isenzo sokuvala esiragela phambili. Umphumela wokuthintana ukhuphula umfutho wokuthintana hlangana nediski nesivalo, ukuqinisekisa ukuvala okuqinileko.
• Qaphela: Umklamo weshafu eyomileko uqinisekisa bona ishafu ihlala ingathintwa mazinga womtjhiso, ukugandeleleka, nofana ukugqwala, okwenza bona kube nokuthembeka.

Iinqophiso zethekhnikhi

• Ukuhlanzwa kwamanzi: Amanzi wokusela, amanzi asilapheleko, kanye neenhlelo zokuthutha indle (kutlhoga ukuvalwa okuphezulu malungana namazinga wokuhlanzeka).
• Ibubulo lamakhemikhali: Uketshezi olubolako, ama-esidi, nama-alkali (ishafu eyomileko ivikela ekuhlaselweni ngamakhemikhali).
• Iinhlelo ze-HVAC: Amaphayiphi womoya nokufuthumala (i-torque ephasi yokusebenza njalo).
• I-Petrochemical & Oil/Gas: Iindaba ezingasizi ezifana namafutha, igesi, kanye nama-solvents (ukuvala okuthembekileko eenkambisweni eziqakathekileko).
• Ukudla neenselo: Iinsetjenziswa zokuhlanzeka (ama-seal ahambisana ne-FDA aqinisekisa ukuphepha komkhiqizo).

• Iinzuzo phezu kwamavalvu wesintu

  • Ukuvala okuphezulu: Ukuvala okuthambileko kuqeda ukuvuza, okufanele ukusetjenziswa okutlhoga ukuvikelwa kwebhoduluko nofana ukuhlanzeka okuphezulu.
  • Ukusebenzisa kuhle amandla: Ukusebenza nge-torque ephasi kwehlisa iimfuneko zamandla wokusebenza, kwehlisa iindleko zokusebenza.
  • Ukuphila isikhathi eside: Umklamo one-double-excentric unciphisa ukuguga, ngesikhathi ishafu eyomileko ivikela ekugqwaleni, ikhulisa ipilo yokusebenza.
  • Ukonga Isikhala: Isakhiwo esincani nasiqathaniswa namavalvu wesango nofana we-globe, esilungele ukufakwa kwesikhala esincani.

  Amathiphu wokulondoloza nokufakwa

  • Ukufakwa: Qinisekisa bona amafletjhi ahlangene begodu amabhawudo aqiniswe ngokulinganako ukubalekela ukugandeleleka emzimbeni wevalvu.
  • Ukutlhogonyelwa: Hlola qobe isivalo esithambileko bona sigugile begodu usifake esikhundleni saso nangabe silimele. Gcoba ishafthi ne-actuator ngeenkhathi ezithileko ukuqinisekisa ukusebenza kuhle.
  • Ukugcina: Beka endaweni eyomileko, enganathuli ngevalvu evulekile kancani ukuqeda ukugandeleleka kwesivalo.
  Ivalvu le ihlanganisa ubunjiniyela obuthuthukileko nomklamo osebenzako, inikela ngesisombululo esithembekileko nesingabizi khulu seentlhogo zesimanjemanje zokulawula ukugeleza kweemboni. Ukwenza ngendlela oyifunako (isib., ukuthuthukisa izinto namkha ukugcotshwa okukhethekileko), sibawa uthintane nomkhiqizi.
