"Mokhoa oa ho khetha Globe Valve ka nepo: Tataiso ea Mefuta le Maemo a Ts'ebeliso"
1,Kakaretso
Globe valve ke mofuta oa valve o sebelisoang hangata, haholo-holo o sebelisetsoang ho khaola mokelikeli liphaepheng. Khetho e nepahetseng ea li-valve tse koalang ke senotlolo sa ho netefatsa ts'ebetso e tloaelehileng ea liphaephe. Tataiso ena e tla u tsebisa mokhoa oa ho khetha valve ea ho koala ka nepo, ho kenyelletsa le mofuta oa eona le boemo ba ts'ebeliso.
2,Mofuta oa valve ea ho koala
1. E arotsoe ka sebopeho sa valve:
a) Ho otloloha ho pholletsa le valve ea globe: mocha oa mokelikeli o otlolohile, o na le sebopeho se bonolo le ho hanyetsa ho phalla ha tlaase, ho etsa hore e sebelisoe haholo.
b) Angle globe valve: Lekanale la mokelikeli le ka lehlakoreng la 90 degree, le nka sebaka se senyenyane mme le loketse maemo a nang le sebaka se lekanyelitsoeng.
c) Valofo ea globe ea hona joale e tobileng: Mokelikeli oa mokelikeli o otlolohile 'me o na le khanyetso e phahameng ea phallo, e etsang hore e tšoanele maemo a nang le maqhubu a tlaase a ho bula le a ho koala.
2. E arotsoe ka lisebelisoa tsa valve:
a) Carbon steel globe valve: e loketse lits'ebetso tse akaretsang tsa indasteri tse nang le mecha ea litaba joalo ka metsi, oli, mouoane, jj.
b) Valofo ea tšepe ea tšepe e sa hloekang: e loketse tikoloho e nang le litlhoko tse phahameng tsa bohloeki, joalo ka lino tse senyang, likhase, lik'hemik'hale, jj.
c) Fluorine lined globe valve: e loketse tikoloho e nang le lik'hemik'hale tse senyang, li-acid tse matla, li-alkali tse matla, le mecha e meng ea litaba.
3. E arotsoe ka mokhoa oa ho khanna:
a) Sesepa sa ho koala ka letsoho: Laola ho bula le ho koala ha valve ka ho potoloha kutu ea valve ka letsoho, e bonolo ebile e bonolo ho sebetsa, e loketseng khatello e tlase le lits'ebetso tse nyane tsa bophara.
b) Motlakase oa lefats'e oa motlakase: Ho laola ka mokhoa o itekanetseng ho finyelloa ka ho khanna sekhahla sa valve ho potoloha ka mochine oa motlakase, o loketseng khatello e bohareng le e phahameng, lisebelisoa tse kholo tsa bophara.
c) Pneumatic globe valve: E khannoa ke khatello ea moea ho potoloha sekhahla sa valve, ho finyella taolo e ikemetseng, e loketseng khatello e bohareng le e phahameng, maemo a maholo a bophara.
3,Maemo a ts'ebeliso ea li-valve tsa lefats'e
1. Sistimi ea phepelo ea metsi: e sebelisetsoang ho khaola mehloli ea metsi, ho fihlella ho qala sistimi, ho koala le ho hlokomela.
2. Indasteri ea peterole: e sebelisetsoang ho khaola mecha ea litaba e fapaneng, joalo ka oli, khase, metsi, joalo-joalo, ho netefatsa polokeho ea tlhahiso.
3. Indasteri ea ho fehla matla a mocheso: e sebelisetsoang ho khaola mecha ea litaba e kang metsi a chesang le mouoane, ho netefatsa ts'ebetso e sireletsehileng ea li-boilers le lisebelisoa tsa mocheso.
4. Indasteri ea lijo le lino: e ne e sebelisoa ho khaola mecha ea litaba e kang lijo le lino, ho netefatsa bohloeki ba tikoloho ea tlhahiso.
5. Indasteri ea meriana: e sebelisetsoang ho khaola thepa e tala ea meriana, lithethefatsi le mecha e meng ea litaba ho finyella litlhoko tse tiileng tsa tlhahiso.
6. Indasteri ea ts'ireletso ea tikoloho: e sebelisetsoang ho khaola mecha ea litaba e kang likhoerekhoere le seretse, le ho finyella ts'ebetso e tloaelehileng ea lisebelisoa tsa ts'ireletso ea tikoloho.
4,Litlhokomelo bakeng sa ho khetha li-valve tse koalang
1. Khetha thepa e nepahetseng ea li-valve ho ea ka thepa ea sehare (e kang ho senya, mocheso, khatello, joalo-joalo).
2. Khetha mofuta o nepahetseng oa li-valve ho latela khatello ea moralo, mocheso oa moralo, le bophara ba phala.
3. Nahana ka mokhoa oa ho khanna oa li-valve 'me u khethe li-valve tsa ho koala ka letsoho, tsa motlakase kapa tsa pneumatic tse thehiloeng ho maemo le litlhoko tsa sebaka.
4. Nahana ka boemo ba ho kenya le tataiso ea valve ho netefatsa ts'ebetso ea eona e tloaelehileng.
5. Khetha li-valve tse hlahisoang ke bahlahisi ba hlomphehang ho netefatsa boleng le tšebeletso ea ka mor'a thekiso ea li-valve.
Ka bokhutšoanyane, khetho e nepahetseng ea li-valve tse koalang e hloka hore ho nahanoe ka botlalo thepa ea seaplane, litlhophiso tsa moralo oa lipeipi, le maemo a ts'ebeliso. Ke tšepa hore tataiso ena e na le thuso ho uena.
