Li-valveha li sebelisoe haholo liindastering tse sa tšoaneng, empa hape li sebelisa libaka tse fapaneng, 'me li-valve tse ling libakeng tse thata tsa ho sebetsa li atisa ho ba le mathata. Kaha li-valve ke lisebelisoa tsa bohlokoa, haholo-holo bakeng sa li-valve tse ling tse kholo, ho thata ho li lokisa kapa ho li fetola hang ha bothata bo hlaha. Ka hona, ke habohlokoa ka ho khetheha ho etsa mosebetsi o motle oa tlhokomelo le tlhokomelo ea letsatsi le letsatsi. Ha re shebeng malebela a mang mabapi le tlhokomelo ea li-valve.
1. Polokelo le tlhahlobo ea letsatsi le letsatsi eali-valve
1. Sephahla se lokela ho bolokoa ka kamoreng e omeletseng le e nang le moea o motlakase, 'me lipheletsong tse peli tsa phasejeng li tlameha ho thibeloa.
2. Li-valvee bolokiloeng nako e telele e lokela ho hlahlojoa khafetsa, litšila li lokela ho tlosoa, 'me oli e khahlanong le mafome e lokela ho apesoa holim'a sebaka sa ho sebetsa.
3. Ka mor'a ho kenya, tlhahlobo ea kamehla e lokela ho etsoa, 'me lintlha tse ka sehloohong tsa tlhahlobo ke:
(1) Ho roala ha sebaka se tiisang.
(2) Ho roala khoele ea trapezoidal ea kutu le linate tsa kutu.
(3) Ho sa tsotellehe hore na filler e siiloe ke nako ebile ha e sebetse, haeba e senyehile, e lokela ho nkeloa sebaka ka nako.
(4) Ka mor'a hore valve e ntlafatsoe le ho bokelloa, tlhahlobo ea ts'ebetso ea ho tiisa e lokela ho etsoa.
2. Mosebetsi oa tlhokomelo ha valve e tlotsoa
Tlhokomelo ea litsebi tsabelofopele le ka mor'a ho tjheseletsa le ho hlahisa li phetha karolo ea bohlokoa tšebeletsong ea valve tlhahiso le ts'ebetso, 'me tlhokomelo e nepahetseng le e hlophisehileng le e sebetsang e tla sireletsa valve, ho etsa hore valve e sebetse ka mokhoa o tloaelehileng le ho lelefatsa bophelo ba tšebeletso ea valve. Tlhokomelo ea li-valve e ka bonahala e le bonolo, empa ha ho joalo. Hangata ho na le likarolo tsa mosebetsi tse hlokomolohuoang.
1. Ha valve e tlotsoa ka mafura, bothata ba ente ea mafura hangata bo hlokomolohuoa. Ka mor'a hore sethunya sa ente ea grease se etsoe mafura, mosebeletsi o khetha valve le mokhoa oa ho kopanya ente ea grease ho phethahatsa ts'ebetso ea ente ea grease. Ho na le maemo a mabeli: ka lehlakoreng le leng, palo ea ente ea grease e nyenyane, ente ea mafura ha e lekane, 'me sebaka sa ho tiisa se apara kapele ka lebaka la khaello ea mafura. Ka lehlakoreng le leng, ente e feteletseng ea mafura e baka tšenyo. Lebaka ke hobane ha ho na palo e nepahetseng ea matla a ho tiisa a li-valve tse fapaneng ho latela mofuta oa li-valve. Bokhoni ba ho tiisa bo ka baloa ho latela boholo le mofuta oa valve, ebe palo e loketseng ea mafura e ka kenngoa ka mokhoa o utloahalang.
Ea bobeli, ha valve e tlotsoa ka mafura, bothata ba khatello hangata bo hlokomolohuoa. Nakong ea ts'ebetso ea ente ea mafura, khatello ea ente ea mafura e fetoha khafetsa litlhōrōng le liphuleng. Khatello e tlase haholo, ho lutla ha tiiso kapa khatello ea ho hloleha e phahame haholo, kou ea ente ea mafura e koetsoe, mafura a tiisong a thatafalitsoe, kapa selikalikoe sa ho koala se notletsoe ka bolo ea valve le poleiti ea valve. Hangata, ha khatello ea ente ea grease e le tlase haholo, grease e kenngoeng hangata e phallela ka tlas'a sekoti sa valve, seo hangata se hlahang li-valve tse nyenyane tsa heke. Haeba khatello ea ente ea grease e phahame haholo, ka lehlakoreng le leng, hlahloba molomo oa ente ea grease, 'me u e nkele sebaka haeba lesoba la mafura le thibiloe; Ka lehlakoreng le leng, ho thatafala ha mafura, moo tharollo ea ho hloekisa e sebelisetsoang khafetsa ho nolofatsa setlolo se hlōlehileng sa ho tiisa le ho se nkela sebaka ka grease e ncha. Ho phaella moo, mofuta oa ho tiisa le thepa ea ho tiisa le eona e ama khatello ea mafura, mefuta e fapaneng ea ho tiisa e na le khatello e fapaneng ea grease, ka kakaretso, khatello ea grease e thata e phahame ho feta tiiso e bonolo.
Ho lumeloa hore ho etsa mosebetsi o ka holimo ho thusa haholo ho lelefatsa bophelo ba tšebeletso eabelofo, ’me ka nako e tšoanang, e ka boela ea fokotsa mathata a mangata a sa hlokahaleng.
