Ngaba i-stem yesango le-STAX ye-STAX ye-STAXOL ithembekile ngaphezu kwesiqu esifihliweyo?

Kwiinkqubo zemizi mveliso,I-valves yesangozizinto eziphambili zokulawula ukuhamba kwamatyisi, phakathi kwendawo yokuphuma kwesango kunye neevalve ezifihliweyo zesango. Ke, zinyuka iivalves zesango elinyukayo zinokuthenjwa ngakumbi kune-valve efihlakeleyo?

Ngokwembono yenkqubo yesakhiwo, intambo ye-valve sup vate yesango ye-Stemp ye-Stemp ye-Stemp ityhilwe, kwaye isango liqhutywa ukuba livule kwaye livale ngokuphakanyiswa kwe-valve. Olu luyilo lwenza indawo yokuphakamisa i-valve yesango icace gca ekuqaleni, kwaye umqhubi unokugweba ngobume bendawo yesango. Ngapha koko, i-valve stem ayingenisi ngqo ngqone ne-Prerosion, ithintele ukususwa kwentambo ye-valve stem ophakathi kunye nokunciphisa umngcipheko we-chaming yesango kunye nokungakwazi ukuvula kwaye uvaliwe ngokwesiqhelo somonakalo. Ukusetyenziswa kwexesha elide, ukuthembeka kwamasango kuqinisekisiwe ngakumbi.

Umsonto we-valve stem ye-valve yesango efihliweyo isekwe ngaphakathi kwi-valve, kwaye intshukumo yesango ixhomekeke kwisenzo esidibeneyo sokujikeleza kunye nokuphakamisa isiqu se-valve. Nangona isakhiwo se-valve yesango esifihlakeleyo se-Stem se-Stem siqulathe kwaye sihlala kwindawo encinci, i-valve stem iconjululwa ngokulula yindawo ephakathi ngenxa yokuntywiliselwa kwexesha elide. Nje ukuba intambo ye-valve ye-varve ifakwe kuhleliwe, i-valve yesango iya kufumana i-jamming ngexesha lokusebenza, kwaye ize isilele ekuvulekeni nasekuchaphazelekeni okwesiqhelo, ichaphazele ukuqiniseka kwe-valve yesango. Ngamanye amaxesha imibhobho yekhemikhali ebonakalayo kakhulu, isiphene se-valve yesango esifihliweyo sibonakala ngakumbi, ngelixa isiqu esibonakalayoI-valves yesango, kunye ne-valve yabo yangaphandle, banokuphepha ngokufanelekileyo iingxaki.

Nangona kunjalo, i-valve yesango evulekileyo ayikho ngaphandle kokuzibamba kwayo. Ngenxa yempawu zayo zesakhiwo, i-valve yesango elinyukayo ihlathini ngaphezulu kune-valve enefilikisi efihlakeleyo. Kwezinye iindawo ezineemfuno ezingqongqo zendawo, ufakelo lweevalves zesango ezinyukayo zinokulinganiselwa. Nangona kunjalo, ngokubanzi, kwiimeko ezikhoyo zokusebenza, ukunyuka kwe-Stem Studing Stemp zinezibonelelo ezibalulekileyo ekuthembekeni. Ayinakubonisa kuphela imeko yokutshintsha ngokuchanekileyo, kodwa ikwanciphisa ithuba lokungaphumeleli kubangelwa kukungabikho kokungabinamsebenzi, ukuqinisekisa ukusebenza kwexesha elide le-valve yesango.

Ke, ayinakuchazwa nje ukuba i-valve yesango ye-STE SE-STE SEBENZISIWEYO EKUFUNDILEYO NOKUGQIBELAI-valves yesango, kodwa kwiimeko apho iimfuno zokuthembeka okuphezulu kunye nemvume yeemeko zendawo, ukunyuka ukunyuka kwe-Stem Stemps zihlala ziluhlobo olungcono.
