Valve ea Serurubele ke eng?
Valve ea serurubele e bolela valve e nang le karolo e koalang (diski ea valve kapa poleiti ea serurubele) e le disc, e potolohang ho potoloha axis ea valve ho fihlella ho buloa le ho koaloa. E sebelisoa haholo bakeng sa ho seha le ho kokota phaepheng. Karolo ea ho bula le ho koala valve ea serurubele ke poleiti ea serurubele e bōpehileng joaloka disc e potolohang axis ea eona 'meleng oa valve ho fihlela morero oa ho bula le ho koala kapa ho laola.
1. Sebopeho sa valve ea serurubele
Valve ea serurubele e entsoe haholo-holo ka 'mele oa valve, poleiti ea serurubele, kutu ea valve, lesale la ho tiisa le sesebelisoa sa phetisetso. 'Mele oa valve o silindara, o na le boss ea silindara likarolong tse ka holimo le tse ka tlase bakeng sa ho kenya kutu ea valve. Valve ea serurubele e hokahantsoe haholo le phaephe ka flange; haeba khokahano ea clamp e amoheloa, bolelele ba eona ba sebopeho ke bo bonyenyane ka ho fetisisa. ?Thupa ea valve ke shaft e potolohang ea poleiti ea serurubele, 'me pheletso ea shaft e amohela sebopeho sa ho tiisa lebokose la ho tlatsa ho thibela ho lutla ha seaplane. Qetello e ka holimo ea kutu ea valve e hokahantsoe ka ho toba le sesebelisoa sa phetisetso ho fetisa torque. Poleiti ea serurubele ke karolo ea ho bula le ho koala ea valve ea serurubele. Ho ea ka mofuta oa khokahano, e ka aroloa ka khokahano ea flange le khokahano ea clamp; ho ea ka mokhoa oa phetisetso, e ka aroloa ka letsoho, phetisetso ea gear, pneumatic, hydraulic le motlakase.
Sekhutlo ho tloha ho buleng ka botlalo ho isa ho koaleng ka botlalo ha valve ea serurubele hangata se ka tlase ho 90°. Valve ea serurubele le kutu ea serurubele ka botsona ha li na bokhoni ba ho itlama. E le ho beha poleiti ea serurubele, ho lokela ho kenngoa sesebelisoa sa ho fokotsa li-worm gear kutung ea valve. Tšebeliso ea sesebelisoa sa ho fokotsa li-worm gear ha e etse feela hore poleiti ea serurubele e be le bokhoni ba ho itlama le ho emisa poleiti ea serurubele boemong bofe kapa bofe, empa hape e ka ntlafatsa ts'ebetso ea ts'ebetso ea valve.
2. Molao-motheo oa ho sebetsa oa valve ea serurubele
Disiki ea valve ke diski. Ha e potoloha kutu ea valve, diski ea valve e potoloha 90° ka har'a sebaka sa setulo sa valve ho fihlela ho buloa le ho koaloa ha valve. E bapala karolo ea ho tima ka har'a phaephe. E ka boela ea fetola phallo. ??
Melemo ea valve ea serurubele: sebopeho se bonolo, bophahamo ba khanya, ts'ebetso e bonolo, ho koala hantle.
3. Tlhophiso ea li-valve tsa serurubele
Li-valve tsa serurubele li ka aroloa ka li-valve tse tharo tse sa tloaelehang (Triple offset) tsa serurubele, li-valve tsa serurubele tse sebetsang hantle (tseo hape li bitsoang li-valve tsa serurubele tse nang le mebala e 'meli), le li-valve tsa serurubele tse bohareng (tseo hape li bitsoang li-valve tsa setulo sa serurubele sa rabara) ho latela sebopeho sa sebopeho.
Ho ya ka sebopeho sa ho kwala, di ka arolwa ka mofuta wa ho kwala ho bonolo le mofuta wa ho kwala ho thata (di-valve tsa serurubele tse kwala ho thata di arotswe ka di-valve tsa serurubele tse kwala ho nang le mekhahlelo e mengata le di-valve tsa serurubele tse kwala ho tshepe tse hlwekileng). Mofuta wa ho kwala ho bonolo hangata o sebedisa ho kwala lesale la rabara, mme mofuta wa ho kwala ho thata hangata o sebedisa ho kwala lesale la tshepe.
4. Melao-motheo ea khetho ea li-valve tsa serurubele
-Kaha tahlehelo ea khatello ea li-valve tsa serurubele e kholo haholo ha e bapisoa le li-valve tsa heke le li-valve tsa bolo, li loketse litsamaiso tsa liphaephe tse nang le litlhoko tse fokolang tsa tahlehelo ea khatello.
-Kaha li-valve tsa serurubele li ka sebelisoa bakeng sa taolo ea phallo, li loketse liphaephe tse hlokang taolo ea phallo.
-Ka lebaka la mefokolo ea sebopeho sa valve ea serurubele le thepa ea ho koala, ha e ea lokela litsamaiso tsa liphaephe tse nang le mocheso o phahameng le khatello e phahameng. Mocheso o akaretsang oa ts'ebetso o ka tlase ho 300°C 'me khatello e tloaelehileng e ka tlase ho PN40.
-Kaha valve ea serurubele e na le bolelele bo bokhutšoanyane ba sebopeho 'me e ka etsoa bophara bo boholo, ho eletsoa ho sebelisa valve ea serurubele maemong ao bolelele ba sebopeho bo hlokahalang hore bo be bo bokhutšoanyane kapa valve ea bophara bo boholo (joalo ka DN1000 kapa ho feta).
-Kaha valve ea serurubele e ka buloa kapa ea koaloa ka ho potoloha 90° feela, ho eletsoa ho sebelisa valve ea serurubele maemong ao ho hlokahalang ho bula le ho koala ka potlako.
Kakaretso
Mebaraka ea li-valve tsa lirurubele e ntse e hola ka potlako lilemong tsa morao tjena, 'me maemo a bafani ba li-valve tsa lirurubele a ntse a fetoha. Ha re khethafektheri ea li-valve tsa serurubele, re hloka ho kopanya litlhoko tsa rona, tse kang boleng, theko, tšebeletso le lintlha tse ling, ho khethamoetsi oa li-valve tsa serurubelee fihlelang litlhoko tsa hau.
