E 'ngoe ea mefuta e atileng haholo ea li-valve ke li-valve tsa globe.Sengoliloeng sena se khuts'oane, re hlalosa hore na li-valve tsa lefats'e li sebetsa joang, ho kenyeletsoa melemo le mathata a tsona.
Sesepa sa globe ke eng, hape se sebetsa joang?
Ho etsa qeto ea hore na valve ea lefats'e e nepahetse bakeng sa ts'ebeliso ea hau, nahana ka likarolo tsa eona tse 3 tsa mantlha.Qalong, li-valve tsa ts'ebetso ea mahlakoreng, tse bontšang hore li bulehile kapa li koala ho latela motsamao oa ho ea holimo le tlase oa kutu.Ea bobeli, li lumella ho potoloha ha metsi, ho li tlohela kapa ho sisinyeha.Li-valve tse ling li na le li-valve tse bulehileng le tse koalehileng feela, empa li-valve tsa lefats'e li ka khoaela ho phalla ntle le ho e emisa ka botlalo.Taba ea boraro, li baka tahlehelo e kholo ea hlooho ha e bapisoa le li-valve tse ling tse fapaneng, e leng phapanyetsano bakeng sa lits'ebeletso tsa ho thetheha.
Hore na li-valve tsa lefatše li sebetsa joang
Ho tsoa ka ntle, li-valve tsa lefats'e li na le likarolo tse tharo, lebili la letsoho, sekoti le 'mele.Bonnet e boloka kutu, hammoho le ha lebili la letsoho le phethola, kutu e senyeha holimo le tlase ka har'a bonete.Qetello ea kutu e na le ntho e nyane e bitsoang disk kapa plug, e ka bang tšepe kapa e seng tšepe mme e ka fumaneha ka mefuta e fapaneng, ho latela tlhoko.
Har'a melemo ea mantlha ea li-valve tsa lefats'e ke bokhoni ba tsona ba ho khina kapa ho laola phallo.Ntle le ho koaloa kapa ho buloa, li ka boela tsa buleha.Sena se o lumella ho fetola potoloho ntle le ho e tlohela ka ho feletseng.
Bothata bo boholo ba li-valve tsa lefats'e ke tahlehelo e kholo ea hlooho eo ba e hlahisang.Ho lahleheloa ke hlooho, ho boetse ho bitsoa khatello ea kelello, ho bolela boholo ba liphihlelo tsa mokelikeli oa ho hanyetsa ha o ntse o phalla ka liphaephe.Ha khanyetso e ntse e eketseha, khatello ea maikutlo e lahlehang haholoanyane.Matla a khoheli, khohlano (ea mokelikeli khahlano le mabota a phala), le moferefere kaofela li baka tahlehelo ena.Li-valve le li-fittings li baka tahlehelo ea khatello haholo-holo ka moferefere.
Li-valve tsa globe li qobella mokelikeli ho fetola litaelo ha o ntse o feta, o baka tahlehelo le moferefere.Palo e nepahetseng ea tahlehelo e ipapisitse le lintlha tse joalo ka sekhahla sa mokelikeli le phapang ea ho hohla.Leha ho le joalo, ho ntse ho khonahala ho hlahloba tahlehelo ea khatello ho tsoa ho li-valve tse fapaneng u sebelisa metric e bitsoang L/D coefficient.
Nako ea ho sebelisa li-valve tsa globe
Li-valve tsa Globe li nepahetse neng kapa neng ha u hloka ho tsamaisa phallo, empa ha ua tlameha ho imeloa kelellong ka lebaka la tahlehelo ea khatello ea maikutlo.Lisebelisoa tse ling li kenyelletsa:
