Iivalvu zeTitanium
Ingcaciso yeMveliso
Iivalvu zeTitanium Zizixhobo zokulawula ulwelo ezenziwe ikakhulu ngee-alloy ze-titanium okanye ze-titanium. Ngenxa yokumelana kwazo okugqwesileyo kokugqwala, amandla aphezulu athile, kunye nokuguquguquka kobushushu obubanzi, ziye zaba sisisombululo esikhethwayo kwiimeko ezigqithisileyo zokusebenza ekucutshungulweni kweekhemikhali, ubunjineli bolwandle, i-aerospace, kunye nezinye iinkalo. Zisebenzisa iipropati ezikhethekileyo zesinyithi se-titanium kunye nee-alloy zayo, ii-valve ze-titanium zisebenza njengezixhobo ezibalulekileyo zokulawula ukuhamba kolwelo, ukulawula amazinga okuhamba, kunye nokulawula uxinzelelo kwiinkqubo zemibhobho. Umgaqo wazo oyintloko wokusebenza uhambelana nee-valve zesiqhelo, kodwa umaleko we-oxide oxineneyo owenziwe ngokwemvelo (TiO₂) kumphezulu we-titanium wenza ukuba kusebenze ixesha elide kwindawo ezigqwala kakhulu. Nokuba yonakele, lo maleko we-oxide uyazilungisa xa kukho ioksijini eyaneleyo, ukubonelela ngokhuseleko oluqhubekayo lwevalve.
Iimbonakalo
Iimpawu zeevalvu zetitanium zivela kakhulu kwiimpawu ezikhethekileyo zezinto ezenziwe nge-titanium kunye ne-titanium alloys. Xa zidityaniswe nokuguquguquka koyilo lwesakhiwo sevalvu, oku kudala iingenelo eziphambili ezahlukileyo kwizinto zevalvu zemveli ezifana nentsimbi engagqwaliyo kunye nentsimbi ephosiweyo.
Nangona kunjalo, kukho imida ethile yesicelo, enokuhlelwa ngolu hlobo lulandelayo:
1. Ukumelana nokugqwala okungaqhelekanga (Inzuzo engundoqo)
Umphezulu weTitanium wenza umaleko oxineneyo weTiO₂. Le filimu iyazilungisa ngokukhawuleza nokuba yonakele, nto leyo evumela ukusebenza kwayo kudlule kakhulu kwiivalvu zesinyithi zemveli kwiindawo ezininzi ezirhabaxa.
Iyamelana namanzi olwandle kunye nezisombululo ze-chloride ezixineneyo kakhulu, kwaye inokumelana okugqwesileyo nokugqwala kwemingxuma kunye ne-cravice;
Imelana ne-media efana ne-sulfuric acid, i-acetic acid, kunye ne-alkalis ezinamandla (ngaphandle kwee-asidi ezinciphisa kakhulu ezifana ne-hydrochloric acid egxininisiweyo kunye ne-hydrofluoric acid);
Kwizicelo ezifana nemizi-mveliso ye-chlor-alkali kunye nokususwa kwetyuwa emanzini olwandle, ubomi bayo benkonzo bude ngokuphindwe ka-3-5 kuneevalvu zentsimbi engagqwaliyo.
2. Amandla Aphezulu Acacileyo Aneengenelo Ezilula Ezibalulekileyo
Uxinano lweTitanium yi-4.51 g/cm³ kuphela (malunga ne-60% yentsimbi), kodwa amandla ayo okutsalwa adlula i-895 MPa (kusetyenziswa i-TC4 titanium alloy njengomzekelo), nto leyo enika umlinganiselo wamandla nobunzima odlula kakhulu ezinye izinyithi.
Oku kunciphisa kakhulu ubunzima benkqubo yemibhobho iyonke, nto leyo eyenza ukuba ifaneleke ngakumbi kwiinqwelomoya, elwandle, nakwezinye iinkqubo ezifuna izisombululo ezilula.
Iivalvu zifuna i-torque ephantsi yokusebenza, nto leyo evumela ukuguquguquka okukhulu ekukhetheni i-actuator kunye nokugcina indawo yokufaka.
3. Ukusebenza Okuzinzileyo Kumaqondo Obushushu Abanzi
Iivalvu zeTitanium zimelana namaqondo obushushu agqithisileyo, zisebenza ukusuka kwi -269°C (iimeko ze-helium cryogenic ezingamanzi) ukuya kwi-500°C (iindawo ezinobushushu obuphezulu), kwaye zinomngcipheko omncinci wokuqhekeka okanye ukuguquka ngexesha lokutshintsha kobushushu ngokukhawuleza.

4. Iipropati zokuhambelana kwezinto eziphilayo kunye neempawu ezingezizo zemagnethi
I-Titanium ayinabungozi kwaye ayinamagnethi, ayibonisi mpendulo ingako kwizicubu zomntu kunye nolwelo lomzimba ngelixa ithintela ukuphazamiseka kwe-electromagnetic. Oku kwandisa imida yokusetyenziswa kwayo kwiindawo ezikhethekileyo.
5. Iinkqubo zonyango: Zisetyenziswa kwiivalvu zentliziyo ezenziweyo kunye nemibhobho yokuhambisa ulwelo olungenazintsholongwane ukuze kwenziwe amayeza;
Izixhobo Zokuchwetheza ngokuchanekileyo: Zilungele izixhobo ze-MRI, iinkqubo zolwelo ukuthintela ukuphazamiseka kwe-electromagnetic.
Ukuqhuba okuphantsi kobushushu: Ukugqwesa kabini ekusebenzeni kakuhle kwamandla kunye nokhuseleko
Ukuqhuba kobushushu beTitanium yi-1/5 kuphela yentsimbi kunye ne-1/16 ye-aluminium, nto leyo ethintela ngempumelelo ukudluliselwa kobushushu kwiindawo zeevalvu.
Kwiimeko zobushushu obuphezulu: Inciphisa ukuvuza kobushushu, inciphisa ukusetyenziswa kwamandla, kwaye ithintela iingozi zokutsha komphezulu.
Kwiimeko zobushushu obuphantsi, inciphisa ukungena kobushushu ngaphandle, inciphisa ilahleko zomphunga wesixhobo.
