Li-valve tsa serurubele li sebetsa joang?

Valve ea serurubeleke mofuta oa valve e sebelisang karolo ea ho bula le ho koala disc ho busetsa hoo e ka bang 90° ho bula, ho koala kapa ho lokisa sekhahla sa phallo ea seaplane. Valve ea serurubele ha e na sebopeho se bonolo feela, boholo bo bonyenyane, boima bo bobebe, tšebeliso e tlase ea thepa, boholo bo bonyenyane ba ho kenya, torque e nyane ea ho khanna, ts'ebetso e bonolo le e potlakileng, empa hape e na le ts'ebetso e ntle ea taolo ea phallo le litšobotsi tsa ho koala, 'me ke e' ngoe ea mefuta ea li-valve tse holang ka potlako lilemong tse leshome tse fetileng. Li-valve tsa serurubele li sebelisoa haholo. Mefuta le bongata ba ts'ebeliso ea eona li ntse li atoloha, 'me li hola ho fihlela mochesong o phahameng, khatello e phahameng, bophara bo boholo, ho tiea ho phahameng, bophelo bo bolelele, litšobotsi tse ntle tsa taolo, le mesebetsi e mengata ea valve e le 'ngoe. Botšepehi ba eona le matšoao a mang a ts'ebetso li fihlile boemong bo phahameng.

Ka ho sebelisa rabara ea maiketsetso e hanyetsanang le lik'hemik'hale holi-valve tsa serurubele, tshebetso yali-valve tsa serurubelee ntlafalitsoe. Kaha rabara ea maiketsetso e na le litšobotsi tsa ho hanyetsa mafome, ho hanyetsa khoholeho ea mobu, botsitso ba litekanyo, ho mamella hantle, ho bopeha habonolo, litšenyehelo tse tlase, jj., rabara ea maiketsetso e nang le thepa e fapaneng e ka khethoa ho latela litlhoko tse fapaneng tsa ts'ebeliso ho fihlela maemo a ts'ebetso ali-valve tsa serurubele.

Hobane polytetrafluoroethylene (PTFE) e na le khanyetso e matla ea mafome, ts'ebetso e tsitsitseng, ha e bonolo ho tsofala, coefficient e tlase ea khohlano, e bonolo ho e theha, botsitso ba litekanyo, 'me e ka ntlafatsa thepa ea eona e felletseng ka ho tlatsa le ho eketsa lisebelisoa tse loketseng, thepa ea ho koala valve ea serurubele e nang le matla a betere le coefficient e tlase ea khohlano e ka fumanoa, 'me meeli ea rabara ea maiketsetso ea hlōloa, kahoo thepa ea polymeric ea polymer e emeloang ke PTFE le thepa ea eona e fetotsoeng ea ho tlatsa e sebelisitsoe haholo ka har'a valve ea serurubele, e le hore ts'ebetso ea valve ea serurubele e ntlafalitsoe haholoanyane.Li-valve tsa serurubeleka mefuta e mengata ea mocheso le likhatello, ts'ebetso e tšepahalang ea ho tiisa le bophelo bo bolelele ba ts'ebeletso li entsoe.

E le ho fihlela litlhoko tsa lits'ebetso tsa indasteri tse kang mocheso o phahameng le o tlase, khoholeho e matla, le bophelo bo bolelele, li-valve tsa serurubele tsa tšepe li ntlafalitsoe haholo. Ka ts'ebeliso ea khanyetso e phahameng ea mocheso, khanyetso e tlase ea mocheso, khanyetso e matla ea mafome, khanyetso e matla ea khoholeho, le lisebelisoa tse matla tsa motsoako ka har'a li-valve tsa serurubele, li-valve tsa serurubele tse koetsoeng tsa tšepe li sebelisitsoe haholo masimong a indasteri a kang mocheso o phahameng le o tlase, khoholeho e matla, le bophelo bo bolelele, 'me li-valve tsa serurubele tse nang le bophara bo boholo (9~750mm), khatello e phahameng (42.0MPa) le mocheso o pharaletseng (-196~606°C) li hlahile, hoo theknoloji ea li-valve tsa serurubele e fihlileng boemong bo bocha.

Ha valve ea serurubele e butsoe ka botlalo, e na le khanyetso e nyane ea phallo. Ha lesoba le le pakeng tsa hoo e ka bang 15°~70°, le ka sebelisoa bakeng sa taolo ea phallo e bonolo, kahoo ts'ebeliso ea valve ea serurubele e tloaelehile haholo tšimong ea phetoho ea bophara bo boholo.

Ka lebaka la motsamao o ka hlakolwang wa poleiti ya serurubele ya valve ya serurubele, boholo ba di-valve tsa serurubele di ka sebediswa bakeng sa mehala e nang le dintho tse tiileng tse leketlileng. Ho itshetlehile ka matla a sekwahelo, e ka sebediswa hape bakeng sa mehala e phofshwana le e nang le di-granular.

Li-valve tsa serurubele li loketse ho laola phallo. Hobane tahlehelo ea khatello ea valve ea serurubele ka phaepheng e kholo haholo, hoo e ka bang makhetlo a mararo ho feta valve ea heke, ha ho khethoa valve ea serurubele, tšusumetso ea tahlehelo ea khatello ea sistimi ea liphaephe e lokela ho nahanoa ka botlalo, 'me matla a poleiti ea serurubele ho jara khatello ea sebaka sa liphaephe ha se koetsoe le 'ona a lokela ho nahanoa. Ho phaella moo, meeli ea mocheso o sebetsang oo thepa ea setulo sa elastomeric e ka etsoang ho oona mochesong o phahameng le eona e lokela ho nahanoa.

Valve ea serurubele e na le bolelele bo bonyenyane ba kaho le bophahamo ka kakaretso, lebelo le potlakileng la ho bula le ho koala, le litšobotsi tse ntle tsa taolo ea mokelikeli. Molao-motheo oa sebopeho sa li-valve tsa serurubele o loketse haholo ho etsa li-valve tse nang le li-large-bore. Ha valve ea serurubele e hlokahala hore e sebelisoe ho laola sekhahla sa phallo, ho bohlokoa ho khetha boholo le mofuta o nepahetseng oa valve ea serurubele e le hore e ka sebetsa hantle le ka katleho.

Ka kakaretso, ho throttling, taolo ea melaoana le seretse se mahareng, bolelele ba sebopeho bo bokhutšoanyane, lebelo la ho bula le ho koala le potlakile, 'me ho hlokahala ho khaola khatello e tlase (phapang e nyane ea khatello), 'me valve ea serurubele ea khothaletsoa. ​​Li-valve tsa serurubele li ka sebelisoa ha ho e-na le phetoho ea maemo a mabeli, kanale e fokotsehileng ea bophara, lerata le tlase, ho ruruha le mouoane, ho lutla ho honyenyane sepakapakeng, le mecha ea phatlalatso e khopisang. Tlas'a maemo a khethehileng a ts'ebetso, phetoho ea throttling, kapa ho tiisa ka thata, ho senyeha ho tebileng, mocheso o tlase (cryogenic) le maemo a mang a ts'ebetso.
