A nemmi kharnak flange Double Eccentric Butterfly Valve (Dry Shaft Type)

Thilri fianternak

A biapimi dirhmun sining hna

1. Double Eccentric Design
   • Pakhatnak Eccentricity: Thevalveshaft cu disc laifang in aa hlat, on/khar lio ah hnahnawhnak a zorter i kharnak cunglei ah a rawkmi a zorter.
   • Pahnihnak Eccentricity: Shaft cu pipeline centerline in aa hlat deuh, cu nih cun “wedging effect” a chuahter i disc a khar tikah sealing riantuannak a tthanchoter.
   • Ṭhathnemnak: A ttha deuhmi kharnak zumhawktlak a pek i single-centric asiloah concentric suaisam he tahchunh tikah riantuannak caan a sauter.
2. A nemmi kharnak thilri
   • Valve nih a nemmi kharnak kuang (a tlangpi in EPDM, NBR, asiloah PTFE in sermi) kha valve pum asiloah disc chungah aa khumh, cu nih cun thli a luh khawh lomi kharnak le media phunphun (tahchunhnak ah, ti, chiti, gas, le a hnahnawh lomi ti) he aa tlak khawhnak a pek.
   • A ṭhatnak: A tlawmmi a luangmi (API 598 asiloah ISO 15848 phunglam a tlinhmi) le rianṭuannak caah a herhmi thazaang tlawmte.
3. Dry Shaft Saknak
   • Shaft cu media luannak he aa dang tein khar a si, cu nih cun ti he direct in pehtlaihnak a kham. Hi suaisam nih hin hri chungin a luang khomi lam kha a hloh i rawkralnak ttihnung a zorter, a hlei in a fakmi pawngkam ah.
   • A biapimi thilri: A ttha ngaimi stem seals (tahchunhnak ah, V-type packing asiloah mechanical seals) nih shaft cung ah a luangmi a um lo ti kha a hngalhter.
4. Flange pehtlaihnak
   • Pipeline ah fawi tein chiah khawhnak ding caah a tlarimi flange interface (tahchunhnak ah, ANSI, DIN, JIS) he sermi a si. A tthencheu mi suaisam nih a fekmi dirhmun a pek i zohkhenhnak a fawiter.

Riantuannak Phunglam

• Onnak: Shaft aa mer tikah,aa dangmi pahnihdisc cu kharnak hmun in aa chawk, a nemmi kharnak in zaangfah tein aa ṭhen. Eccentric offsets nih a hramthawk i pehtlaihnak hnahnawhnak kha a zorter, tluang tein, tlawmte lawng in riantuan khawhnak a tuah.
• Kharnak: Disc cu a hnulei ah aa mer, cun double-ecentric geometry nih a karh thluahmahmi kharnak cawlcanghnak a ser. Wedging effect nih disc le seal karlak i pehtlaihnak thazaang a karhter, fek tein khar khawhnak a tuah.
• Bialehnak: A ro cangmi thinghnah suaisam nih thinghnah cu media lum le kih, hneknak, asiloah rawhnak nih a hnorsuan lo nakhnga a tuah, cu nih cun a dihlak in zumhawktlak sinak a ṭhanchoter.

Technical Specifications

• Ti Thianhnak: Dinnak ti, ti thurhnawm, le ti thurhnawm chuahnak (thianhlimnak phunglam caah kharnak sangpi a herh).
• Chemical Industry: A rawkmi ti, acid, le alkalis (a ro cangmi thinghnah nih chemical tukdohnak in a huhphenh).
• HVAC Systems: Thli lumternak le lumternak pipeline (riantuan lengmang caah a tlawmmi torque).
• Petrochemical & Oil/Gas: Oil, gas, le solvents (a biapi tukmi thil sining ah zumhawktlak tein kharnak) tibantuk a hnah a hnah lomi thilri.
• Rawl le dinmi: Thianhlimnak hmannak (FDA-zulmi hmelchunhnak nih thilri himnak a hngalhter).

• Hlanlio Valve hna nakin a ṭhatnak

  • A ttha deuhmi kharnak: A nemmi kharnak nih a luannak a hloh, pawngkam kilvennak asiloah thianhlimnak sang a herhmi hmannak caah aa tlak.
  • Thazaang ttha tein hman khawhnak: Torque tlawmte hmannak nih riantuannak thazaang a herhmi a zorter, riantuannak man a zorter.
  • Nun sau: Double-ecentric design nih a rawhnak a zorter, cu lio ah a ro cangmi hri nih rawhnak in a huhphenh, riantuannak caan a sauter.
  • Hmunhma khonnak: Gate asiloah globe valve he tahchunh ahcun a hmete in sermi, hmunhma tlawmte lawng chiahnak caah a ttha.

  Zohkhenhnak le chiahnak kong ruahnak cheuhnak

  • Chiahnak: Valve pum cung ah hnahnawhnak hrial khawhnak dingah flanges pawl kha aa tluk tein an um i bolts pawl kha aa tluk tein an hren hna ti kha zohfel.
  • Zohkhenhnak: A nemmi kharnak kha a rawk maw rawk lo ti kha zohfel lengmang law a rawh ahcun thlen. Tluang tein rian a ttuan khawh nakhnga shaft le actuator kha a caancaan ah chiti thuh.
  • Chiahnak: Seal cung i hnahnawhnak zorternak caah valve kha tlawmpal on in a ro i leidip a um lonak hmun ah chiah.
  Hi valve nih hin a sangmi engineering le hman khawhmi suaisamnak a fonh, chanthar riantuannak luannak uknak herhmi caah zumhawktlak le man fawi tein a phichuak a pek. A bik in remh khawhnak (tahchunhnak ah, thilri thlennak asiloah a hleiin thuhnak) caah, sertu kha hal hna.
