Hangata li-valve li hokahanngoa le liphaephe ka litsela tse fapaneng tse kang likhoele, li-flanges, welding, clamp le ferrules.Kahoo, khethong ea tšebeliso, u ka khetha joang?
Mekhoa ea ho hokahanya ha li-valve le liphaephe ke efe?
1. Khokahano ea likhoele: Khokahano ea likhoele ke mokhoa oo lipheletso tse peli tsa valve li sebetsoang ka likhoele tse ka hare kapa likhoele tse kantle ho hokahanya le phaephe.Ka kakaretso, li-valve tsa bolo tse ka tlase ho lisenthimithara tse 4 le li-valve tsa globe, li-valve tsa heke le li-valve tsa ho hlahloba ka tlase ho lisenthimithara tse 2 hangata li entsoe ka likhoele.Sebopeho sa khokahanyo se nang le khoele se batla se le bonolo, boima bo bobebe, 'me ho kenya le ho qhaqha ho bonolo haholoanyane bakeng sa tlhokomelo le ho nkeloa sebaka.Kaha valve e tla atoloha tlas'a tšusumetso ea mocheso o potolohileng le mocheso o bohareng nakong ea ts'ebeliso, ho netefatsa ts'ebetso e ntle ea ho tiisa, li-coefficients tsa ho atolosa tsa lisebelisoa tse peli qetellong ea ho hokahanya li lokela ho nkoa ka botlalo.Ho ka 'na ha e-ba le liteishene tse kholo tsa ho lutla likhokahanong tse khoeleng, kahoo li-sealant, litheipi tse koalang kapa li-filler li ka sebelisoa ho thibela likanale tsena ho eketsa ts'ebetso ea tiiso.Haeba ts'ebetso le thepa ea 'mele oa li-valve li ka chesetsoa, e ka boela ea tiisoa ka mor'a khokahanyo e entsoeng ka khoele.Thobalano e ka ba betere.
2. Khokahano ea Flange: Khokahano ea Flange ke mokhoa o tloaelehileng oa ho hokahanya li-valve.Ho kenya le ho qhaqhoa ho bonolo haholo, 'me khokahanyo ea flange e ka tšeptjoa ha ho tiisoa, e leng ntho e tloaelehileng haholo ka li-valve tse nang le khatello e phahameng le tse kholo.Leha ho le joalo, qetello ea flange e boima, 'me litšenyehelo li batla li le holimo.Ho feta moo, ha mocheso o feta 350 ℃, ka lebaka la khatholoho ea liboutu, li-gaskets le li-flanges, mojaro oa liboutu o tla fokotseha haholo, 'me khokahano ea flange e nang le khatello e matla e ka lutla, e sa lokelang ho sebelisoa.
3. Lihokelo tse cheselitsoeng Lihokelo tse cheselitsoeng hangata li na le mefuta e 'meli ea meaho: socket welding le butt welding.Ka kakaretso, socket welding e sebelisoa bakeng sa li-valve tsa khatello e tlase.Sebopeho sa welding sa li-valve tsa socket welding se bonolo ho sebetsa ebile ho bonolo ho se kenya.Butt welding e sebelisoa bakeng sa valve ea khatello e phahameng e na le litšenyehelo tse phahameng, 'me welding e hloka ho grooved ho ea ka mokhoa oa liphaephe, oo ho leng thata ho o sebetsa, le mokhoa oa ho cheselletsa le oa ho kenya le oona o rarahane le ho feta.Lits'ebetsong tse ling, liteko tsa radiographic tse sa senyeheng le tsona lia hlokahala bakeng sa tjheseletsa ea khokahano.Ha mocheso o feta 350 ° C, mojaro oa liboutu o tla fokotseha haholo ka lebaka la ho phomola ha liboutu, li-gaskets le li-flanges, 'me ho lutla ho ka etsahala khokahanong ea flange ka khatello e kholo ea khatello.
4. Clamp connection Sebopeho sa khokahanyo ea Clamp se tšoana le flange, empa sebopeho sa eona se bobebe 'me theko e tlaase e atisa ho sebelisoa liphaepheng tsa bohloeki le lisebelisoa.Liphaephe tsa bohloeki li hloka ho hloekisoa, 'me ho thibetsoe ka thata ho ba le masala a ho hlahisa libaktheria, kahoo likhokahano tsa flange le likhokahano tse entsoeng ka likhoele ha li tšoanelehe, 'me ho thata ho kenya le ho qhaqha lihokelo tsa welding.Ka hona, likhokahano tsa li-clamp ke tsona tse atileng haholo liphaepheng tse tala.mokhoa oa ho hokahanya.
