Butterfly valve , e tsejoang hape e le valve ea flap, ke valve e bonolo ea ho laola. Ka nako e ts'oanang, e ka boela ea sebelisoa bakeng sa ho fetola taolo ea lipeipi tsa khatello e tlaase. Butterfly valve e bolela valve eo karolo ea eona ea ho koala (disc kapa disc) e leng disc mme e potoloha ho potoloha shaft ea valve ho bula le ho koala. Haholo-holo e bapala karolo ea ho khaola le ho phunya lipeipi. Karolo e bulang le e koalang ea valve ea serurubele ke poleiti ea serurubele e bōpehileng joaloka disc, e potolohang ho pota-pota axis ea eona 'meleng oa valve, e le ho finyella morero oa ho bula, ho koala kapa ho lokisa. Butterfly valve e sebetsa liphaepheng tse fetisang mecha ea litaba e fapaneng e senyang le e sa cheng lits'ebetsong tsa boenjiniere tse kang jenereithara, khase, khase ea tlhaho, khase ea peterole e entsoeng ka metsi, khase ea litoropong, moea o chesang le o batang, ho qhibilihisa lik'hemik'hale, phepelo ea matla le ts'ireletso ea tikoloho, 'me e sebelisoa. ho laola le ho kgaola phallo ya media.
Tšebeliso ea valve ea serurubele
Li-valve tsa butterfly li loketse ho laola phallo. Kaha khatello ea khatello ea valve ea serurubele phapeng e batla e le khōlō, e leng hoo e ka bang ka makhetlo a mararo ho feta ea valve ea heke, ha u khetha valafo ea serurubele, tšusumetso ea tahlehelo ea khatello tsamaisong ea lipeipi e lokela ho nahanoa ka botlalo, le ho tiea ha phaephe e nang le poleiti ea serurubele. khatello e mahareng ha ho koaloa le eona e lokela ho nahanoa. Ho phaella moo, moeli oa mocheso o sebetsang oa lisebelisoa tsa setulo sa elastic ka mocheso o phahameng o tlameha ho nkoa.
Belofo ea serurubele e na le bolelele bo bonyenyane ba sebopeho le bophahamo ka kakaretso, lebelo la ho bula le ho koala kapele, le litšobotsi tse ntle tsa taolo ea mokelikeli. Molao-motheo oa sebopeho sa valve ea serurubele o loketse ka ho fetisisa bakeng sa ho etsa li-valve tsa bophara bo boholo. Ha valve ea serurubele e hlokeha ho laola phallo, ntho ea bohlokoa ka ho fetisisa ke ho khetha ka nepo boholo le mofuta oa serurubele e le hore se sebetse hantle le ka katleho.
Ka kakaretso, ho throttling, taolo le taolo le bohareng ba seretse, bolelele ba sebopeho se khuts'oane le lebelo la ho bula le ho koala ka potlako (1 / 4R) lia hlokahala. Khatello e fokolang ea khatello e tlaase (khatello e nyenyane ea phapang), valve ea serurubele e khothalletsoa.
Butterfly valve e ka sebelisoa ka kanaleng e nang le taolo ea maemo a mabeli le melala, lerata le tlase, cavitation le gasification, palo e nyane ea ho lutla sepakapakeng le bohareng ba abrasive.
Ha valve ea serurubele e sebelisoa tlas'a maemo a khethehileng a ho sebetsa, joalo ka taolo ea throttling, ho tiisa ka thata kapa ho roala ho tebileng, mocheso o tlaase (cryogenic) le maemo a mang a sebetsang, hoa hlokahala ho sebelisa li-valve tse khethehileng tse tharo tsa eccentric kapa tse peli tse nang le tšepe e entsoeng ka tšepe e khethehileng. setiiso le sesebedisoa sa ho laola.

Ke sebaka se setle sa valve ea heke le valve ea ho emisa
Molao-motheo oa khetho ea valve ea serurubele
1. Hobane tahlehelo ea khatello ea valve ea serurubele e batla e le khōlō ha e bapisoa le valve ea heke, e loketse tsamaiso ea lipeipi e nang le litlhoko tsa tahlehelo ea khatello ea lax.
2. Kaha valve ea serurubele e ka fetoloa ka ho phalla, e loketse ho khethoa ka phaephe e hlokang phetoho ea phallo.
3. Ka lebaka la moeli oa sebopeho sa li-valve tsa serurubele le lisebelisoa tsa ho tiisa, ha e loketse mocheso o phahameng le tsamaiso ea lipeipi tsa khatello e phahameng. Mocheso o tloaelehileng oa ho sebetsa o ka tlase ho 300 ¡æ mme khatello ea lebitso e ka tlase ho PN40.
4. Kaha valve ea serurubele e na le bolelele bo bokhutšoane ba sebopeho 'me e ka etsoa ka bophara bo boholo, e lokela ho khethoa bakeng sa liketsahalo tseo bolelele ba mohaho bo hlokahalang hore bo be bokhutšoane kapa bakeng sa li-valve tse kholo tsa bophara (tse kang ka holimo ho DN1000).
5. Kaha valve ea serurubele e ka buloa kapa ea koaloa feela ka ho potoloha 90 ¡ã, ho loketse ho khetha valve ea serurubele tšimong ka litlhoko tsa ho bula le ho koala ka potlako.
