Li-valveke lisebelisoa tsa bohlokoa tlhahisong ea indasteri, mme ts'ebetso ea bona e ama ka kotloloho botsitso le katleho ea ts'ebetso ea tlhahiso. Ka mehlabelofoho hlahloba ho ka fumana le ho rarolla mathata a valve ka nako, ho netefatsa ts'ebetso e tloaelehileng eabelofo, le ho ntlafatsa katleho ea tlhahiso.
Ntlha ea pele, bohlokoa ba tlhahlobo ea ts'ebetso ea valve
1. Netefatsa polokeho le ts'epo:Li-valveke likarolo tsa bohlokoa tsa taolo liphaepheng tsa mokelikeli le tsa khase, 'me li etsa mesebetsi ea bohlokoa ho laola phallo ea mokelikeli, khatello le tsela. Ka lebaka la tšusumetso ea lintho tse kang ts'ebetso ea tlhahiso, lisebelisoa le moralo, ho na le likotsi tse itseng tsa tšebeliso ea li-valve, tse kang ho tiisa ho futsaneha, matla a sa lekaneng, ho hanyetsa ha kutu, joalo-joalo Ka tlhahlobo ea ts'ebetso, ho ka netefatsoa hore valve e ka mamella litlhoko tsa khatello moleng oa mokelikeli, 'me ea qoba ho lutla, tšilafalo, likotsi le mathata a mang a bakoang ke ho tiisa hantle, e le ho netefatsa ts'ebetso e sireletsehileng le e ka tšeptjoang ea tsamaiso.
2. Ntlafatsa boleng ba sehlahisoa le tlholisano ea 'maraka: Litekanyetso tse thata tsa tlhahlobo ea ts'ebetso ke motheo oa ho netefatsa boleng ba lihlahisoa tsa li-valve tsa indasteri. Ka letoto la lits'ebetso tsa tlhahlobo, mathata a ka bang teng a ka fumanoa le ho rarolloa, mme tlholisano ea 'maraka ea lihlahisoa e ka ntlafatsoa. Litekanyetso tse phahameng tsa liteko li boetse li netefatsa hore hobelofoe kopana le maemo a mangata a mangata a hlokang ho sebetsa, joalo ka matla a khatello libakeng tse phahameng tsa khatello, ts'ebetso ea ho tiisa sebakeng se koetsoeng, le ho fetoha ha maemo le ho tšepahala.
3. Tlhokomelo e thibelang le bophelo bo atolositsoeng ba tšebeletso: tlhahlobo ea ts'ebetso e ka hlahloba bophelo ba tšebeletso le ho tšepahala ha valve, e bolela esale pele bophelo ba eona le sekhahla sa ho hlōleha ha ts'ebetso ea tšebeletso, le ho fana ka boitsebiso bakeng sa tlhokomelo. Ka tlhahlobo le tlhokomelo ea kamehla, u ka lelefatsa bophelo ba li-valve tsa hau le ho fokotsa litšitiso tsa tlhahiso le litšenyehelo tsa ho lokisa ka lebaka la ho hlōleha ha li-valve.
4. Ikamahanya le maemo le litlhokahalo tsa taolo: Teko ea tšebetso ea li-valve e hloka ho ipapisa le litekanyetso tse amehang tsa machaba le tsa lehae ho netefatsa hore lihlahisoa li fihlela litlhoko tsa polokeho le boleng. Ho ikamahanya le maemo ha ho thuse feela hore sehlahisoa se netefatsoe, empa hape se fumana tšepo e eketsehileng le kananelo 'marakeng.
