Titanium Valves
Kev piav qhia txog khoom
Titanium valves yog cov khoom siv tswj cov kua dej uas feem ntau yog tsim los ntawm titanium lossis titanium alloys. Nrog lawv txoj kev tiv thaiv corrosion zoo heev, lub zog tshwj xeeb siab, thiab kev hloov pauv kub dav dav, lawv tau dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau cov xwm txheej ua haujlwm hnyav hauv kev ua tshuaj lom neeg, kev tsim kho marine, aerospace, thiab lwm yam teb. Siv cov khoom tshwj xeeb ntawm titanium hlau thiab nws cov alloys, titanium li qub ua haujlwm ua cov khoom siv tseem ceeb rau kev tswj cov kua dej ntws, tswj cov nqi ntws, thiab tswj kev siab hauv cov kav dej. Lawv lub hauv paus ntsiab lus ua haujlwm sib haum nrog cov li qub, tab sis cov txheej oxide ntom ntom (TiO₂) uas tsim los ntawm ntuj tsim ntawm cov titanium nto ua rau kev ua haujlwm ruaj khov mus sij hawm ntev hauv cov chaw muaj corrosive heev. Txawm tias puas tsuaj, cov txheej oxide no kho nws tus kheej thaum muaj oxygen txaus, muab kev tiv thaiv tas mus li rau lub valve.
Cov yam ntxwv
Cov yam ntxwv ntawm cov titanium li qub feem ntau yog los ntawm cov khoom siv zoo tshaj plaws ntawm titanium thiab titanium alloys. Ua ke nrog kev hloov pauv ntawm kev tsim qauv ntawm lub valve, qhov no tsim cov txiaj ntsig tseem ceeb sib txawv ntawm cov khoom siv valve ib txwm muaj xws li hlau tsis xeb thiab hlau cam khwb cia.
Txawm li cas los xij, muaj qee qhov kev txwv ntawm daim ntawv thov, uas tuaj yeem faib ua pawg raws li hauv qab no:
1. Kev Tiv Thaiv Kev Xeb Zoo Tshaj Plaws (Core Advantage)
Cov titanium nto tsim ib txheej TiO₂ passivation ntom ntom. Cov zaj duab xis no kho tau sai txawm tias puas lawm los xij, ua rau muaj kev ua tau zoo dua li cov hlau ib txwm muaj hauv feem ntau qhov chaw corrosive.
Tiv taus dej hiav txwv thiab cov tshuaj chloride uas muaj cov tshuaj ntau, nrog rau kev tiv taus zoo heev rau kev xeb ntawm qhov pitting thiab crevice;
Tiv taus cov tshuaj xws li sulfuric acid, acetic acid, thiab cov alkalis muaj zog (tsis suav nrog cov kua qaub uas txo qis heev xws li concentrated hydrochloric acid thiab hydrofluoric acid);
Hauv cov ntawv thov xws li kev lag luam chlor-alkali thiab kev tshem dej hiav txwv, nws lub neej ua haujlwm ntev dua 3-5 npaug ntawm cov li qub tsis xeb.
2. Lub zog tshwj xeeb nrog cov txiaj ntsig tseem ceeb ntawm kev sib dua
Titanium qhov ceev tsuas yog 4.51 g / cm³ (kwv yees li 60% ntawm cov hlau), tsis tau nws lub zog tensile tshaj 895 MPa (siv TC4 titanium alloy ua piv txwv), ua rau muaj qhov sib piv ntawm lub zog rau qhov hnyav ntau dua li lwm cov hlau.
Qhov no txo qhov hnyav ntawm cov kav dej tag nrho, ua rau nws tsim nyog rau kev tsav dav hlau, tub rog hiav txwv, thiab lwm yam kev siv uas xav tau cov kev daws teeb meem sib dua.
Cov li qub xav tau lub zog qis dua, ua rau muaj kev ywj pheej ntau dua hauv kev xaiv cov actuator thiab txuag qhov chaw teeb tsa.
3. Kev Ua Haujlwm Ruaj Khov Thoob Plaws Qhov Kub Dav Dav
Cov twj tso kua titanium tiv taus qhov kub thiab txias heev, ua haujlwm txij li -269 ° C (kua helium cryogenic conditions) mus txog 500 ° C (qhov chaw kub siab), nrog rau qhov kev pheej hmoo tsawg kawg nkaus ntawm kev tawg lossis deformation thaum lub sijhawm hloov pauv thermal sai.
