Butterfly valve, eo hape e tsejoang e le "flap valve".Karolo ea eona e bulang le e koalang ke poleiti ea serurubele e bōpehileng joaloka disc, e tsitsitseng holim'a kutu ea valve 'me e potoloha ho pota-potile axis ea valve stem ho lemoha ho bula le ho koala.Tsela ea ho tsamaea ha valve ea serurubele ke ho potoloha sebakeng, 'me ho hlokahala feela ho potoloha 90 ° ho tloha ho bulehile ka ho feletseng ho ea ho koaloa ka ho feletseng.Ho phaella moo, poleiti ea serurubele ea valve ea serurubele ka boeona ha e na bokhoni ba ho itšireletsa, 'me mochine o fokotsang lisebelisoa tsa sebōkō o lokela ho kenngoa holim'a stem ea valve.Ka eona, poleiti ea serurubele e na le bokhoni ba ho itšireletsa, hape e ka ntlafatsa ts'ebetso ea ts'ebetso ea valve ea serurubele.
Ho tseba tlhaloso ea valve ea heke le valve ea serurubele, phapang pakeng tsa valve ea heke le valve ea serurubele e hlahisoa ka tlase:
1. Phapang ea bokhoni ba liatleletiki
Tlhalosong e ka holimo, re utloisisa phapang ea tataiso le mokhoa oa ho tsamaea ha li-valve tsa heke le li-valve tsa serurubele.Ho phaella moo, li-valve tsa heke li ka buloa ka ho feletseng le ho koaloa ka ho feletseng, kahoo ha li bulehile ka ho feletseng, li-valve tsa heke li na le khanyetso e nyenyane ea phallo;li-valve tsa serurubele Boemong bo bulehileng ka ho feletseng, botenya ba valve ea serurubele bo baka khanyetso ho sebaka se phallang.Ho phaella moo, valve ea heke e na le bophahamo bo phahameng ba ho bula, kahoo lebelo la ho bula le ho koala le lieha;ha valve ea serurubele e ka buloa le ho koaloa ka ho potoloha 90 ° feela, kahoo lebelo la ho bula le ho koala le potlakile.
2. Phapang lipakeng tsa ts'ebetso le ts'ebeliso
Valve ea heke e na le ts'ebetso e ntle ea ho koala, ka hona e sebelisoa haholo liphaepheng tse hlokang ho tiisoa ka thata 'me ha ho hlokahale hore e fetoloe khafetsa ho khaola mokhoa oa ho potoloha.Valve ea heke e ke ke ea sebelisoa ho lokisa sekhahla sa phallo.Ho phaella moo, hobane lebelo la ho bula le ho koala ha valve ea heke le lieha, ha lea tšoanela phala e lokelang ho khaoloa ka potlako.Tšebeliso ea li-valve tsa serurubele e batla e pharaletse.Li-valve tsa butterfly li ke ke tsa sebelisoa feela ho khaola, empa hape li na le mosebetsi oa ho lokisa boholo ba phallo.Ho phaella moo, valve ea serurubele e bula le ho koala kapele, 'me e ka boela ea buloa le ho koaloa khafetsa, haholo-holo e loketse ho sebelisoa liketsahalong tse hlokang ho bula kapa ho koala kapele.
Boholo ba valve ea serurubele e nyenyane ho feta ea valve ea heke, 'me boima ba eona bo boetse bo bobebe ho feta ba valve ea heke.Ka hona, libakeng tse ling tse nang le sebaka se lekanyelitsoeng sa ho kenya, ho kgothaletswa ho sebelisa serurubele sa serurubele se bolokang sebaka.Har'a li-valve tse nang le bophara bo boholo, valve ea serurubele ke eona e sebelisoang ka ho fetisisa, 'me e boetse e khothalletsoa ho sebelisa valve ea serurubele ka phaephe e bohareng e nang le likaroloana tse nyenyane tsa litšila.
Ha ho khethoa li-valve maemong a mangata a sebetsang, li-valve tsa serurubele butle-butle li nkile sebaka sa mefuta e meng ea li-valve 'me e fetoha khetho ea pele ea basebelisi ba bangata.
3. Phapang ka theko
Tlas'a khatello e tšoanang le tekanyo e tšoanang, theko ea valve ea heke e phahame ho feta ea valve ea serurubele.Leha ho le joalo, tekanyo ea valve ea serurubele e ka etsoa e kholo haholo, 'me theko ea valve e kholo ea serurubele ha e theko e tlaase ho feta ea valve ea heke.
