Balofo e Bonolo ea Ho Tiisa Habeli Eccentric Butterfly (Mofuta oa Dry Shaft)

Tlhaloso ea Sehlahisoa

Likarolo Tse Bohlokoa Tsa Sebopeho

1. Moralo oa Double Eccentric
   • Eccentricity ea Pele: Thebelofoshaft e fokotsehile ho tloha bohareng ba disk, ho fokotsa likhohlano nakong ea ho bula / ho koala le ho fokotsa ho apara holim'a libaka tsa ho tiisa.
   • Botšepehi ba Bobeli: Shaft e tsoela pele ho tlosoa ho tloha setsing sa pipeline, ho theha "phello ea ho nyalana" e matlafatsang ts'ebetso ea ho tiisa ha disc e koala.
   • Molemo: E fana ka ts'epahalo e phahameng ea tiiso le ho lelefatsa bophelo ba ts'ebeletso ha ho bapisoa le meralo e le 'ngoe kapa e bohareng.
2. Mokhoa o Bonolo oa ho Tiisa
   • Sephahla se sebelisa lesale la ho koala le bonolo (leo hangata le entsoeng ka EPDM, NBR, kapa PTFE) le kenngoeng ka har'a 'mele oa valve kapa disc, ho netefatsa hore ho koaloa ha moea le ho lumellana le mecha ea litaba e sa tšoaneng (mohlala, metsi, oli, likhase le metsi a sa tsitsang).
   • Molemo: Litefiso tse tlase tsa ho lutla (ho kopana le litekanyetso tsa API 598 kapa ISO 15848) le torque e nyane e hlokahalang bakeng sa ts'ebetso.
3. Kaho ea Shaft e omileng
   • Shaft e tiisitsoe ka thoko ho phallo ea mecha ea phatlalatso, e thibela ho kopana ka ho toba le mokelikeli. Moralo ona o felisa litsela tse ka bang teng tsa ho lutla ka har'a shaft mme o fokotsa likotsi tsa kutu, haholo-holo libakeng tse mabifi.
   • Karolo ea Bohlokoa: Litiiso tsa boleng bo holimo tsa stem (mohlala, ho paka mofuta oa V kapa litiiso tsa mochini) li netefatsa hore ha ho dutla lehare haufi le shaft.
4. Khokahano ea Flange
   • E entsoe ka li-interfaces tse tloaelehileng tsa flange (mohlala, ANSI, DIN, JIS) bakeng sa ho kenya habonolo liphaepheng. Moralo oa flanged o fana ka botsitso ba sebopeho mme o nolofatsa tlhokomelo.

Molao-motheo oa ho Sebetsa

• Ho bula: Ha shaft e ntse e potoloha, ehabedi-eccentricdisc e tloha sebakeng se koetsoeng, butle-butle e itokolla ho tiiso e bonolo. Li-eccentric offsets li fokotsa khatello ea maikutlo ea pele, li nolofalletsa ts'ebetso e boreleli, ea torque e tlase.
• Ho koala: Disc e potoloha morao, 'me geometry e nang le habeli-eccentric e etsa ketso e tsoelang pele ea ho tiisa. Phello ea ho nyalana e eketsa khatello ea ho kopana pakeng tsa disc le tiiso, ho netefatsa hore ho koaloa ka thata.
• Tlhokomeliso: Moralo o ommeng oa shaft o netefatsa hore shaft e lula e sa angoe ke mocheso oa media, khatello, kapa ho bola, ho matlafatsa ts'epo ka kakaretso.

Litlhaloso tsa Tekheniki

• Phekolo ea Metsi: Metsi a nooang, metsi a litšila le tsamaiso ea likhoerekhoere (e hloka tiiso e phahameng bakeng sa litekanyetso tsa bohloeki).
• Indasteri ea Lik'hemik'hale: Mekelikeli e senyang, li-acid le alkalis (shaft e ommeng e sireletsa khahlanong le tlhaselo ea lik'hemik'hale).
• Litsamaiso tsa HVAC: Liphaephe tse futhumatsang moea le ho futhumatsa (torque e tlase bakeng sa ts'ebetso ea khafetsa).
• Petrochemical & Oli / Gas: Mecha ea litaba e sa tsitsang joalo ka oli, khase le li-solvents (ho koaloa ka mokhoa o tšepahalang lits'ebetsong tse mahlonoko).
• Lijo le Seno: Lisebelisoa tsa bohloeki (litiiso tse lumellanang le FDA li netefatsa polokeho ea sehlahisoa).

• Melemo Ho Feta Li-valve Tsa Setso

  • Ho Tiisa ho Phahameng: Litiiso tse bonolo li felisa ho lutla, tse loketseng lits'ebetso tse hlokang ts'ireletso ea tikoloho kapa bohloeki bo phahameng.
  • Matla a Matla: Ts'ebetso ea torque e tlase e fokotsa litlhoko tsa matla a actuation, e fokotsa litšenyehelo tsa ts'ebetso.
  • Nako e telele: Moralo o nang le likarolo tse peli o fokotsa ho roala, ha shaft e ommeng e sireletsa khahlanong le kutu, e lelefatsa bophelo ba tšebeletso.
  • Ho Boloka Sebaka: Sebopeho se kopaneng ha se bapisoa le li-valve tsa heke kapa tsa lefatše, tse loketseng ho kenya sebaka se lekanyelitsoeng.

  Malebela a Tlhokomelo le Tlhophiso

  • Ho kenya: Etsa bonnete ba hore li-flange li lumellana 'me liboutu li tiisitsoe ka mokhoa o ts'oanang ho qoba khatello ea maikutlo holim'a' mele oa valve.
  • Tlhokomelo: Kamehla hlahloba tiiso e bonolo hore na ha e sebetse 'me u e khutlisetse haeba e senyehile. Lubricate shaft le actuator nako le nako ho netefatsa ts'ebetso e bonolo.
  • Storage: Boloka sebakeng se omeletseng, se se nang lerole le valve e bulehile hanyenyane ho imolla khatello ea maikutlo holim'a tiiso.
  Valve ena e kopanya boenjiniere bo tsoetseng pele le moralo o sebetsang, e fanang ka tharollo e tšepahalang le e theko e tlaase bakeng sa litlhoko tsa mehleng ea kajeno tsa taolo ea phallo ea indasteri. Bakeng sa ho itlhophisa ka mokhoa o ikhethileng (mohlala, lintlafatso tsa thepa kapa litlolo tse khethehileng), ka kopo ikopanye le moetsi.
