Sebaka sa tlhahlobo
Haeba ho se na lintho tse ling tse eketsehileng tse boletsoeng konteraka ea odara, tlhahlobo ea moreki e lokela ho lekanyetsoa ho tse latelang:
a) Ho latela melao ea konteraka ea taelo, sebelisa lisebelisoa le mekhoa ea tlhahlobo e sa senyeheng ho hlahloba li-valve nakong ea ts'ebetso ea kopano.
b) Tlhahlobo ea pono ea li-valve tsa castings e lokela ho lumellana le JB/T 7929.
c) "Boikarabello" le "boikhethelo" liteko tsa khatello.
d) Litlhahlobo tse ling tse ling.
e) Lekola lirekoto tsa ts'ebetso le lirekoto tsa tlhahlobo tse sa senyeheng (ho kenyeletsoa le litlaleho tse boletsoeng tsa tlhahlobo ea radiographic).
Tlhokomeliso: Litlhahlobo tsohle li lokela ho etsoa ho latela mekhoa e ngotsoeng e thehiloeng ho litekanyetso tse lumellanang.
Tlhahlobo
Moetsi oa li-valve o lokela ho etsa tlhahlobo ea pono holim'a 'mele eohle ea li-valve, libonete le likarolo tsa ho tiisa ho sireletsa ho latela melao ea JB/T 7929.
Moetsi oa li-valve o lokela ho hlahloba valve e 'ngoe le e' ngoe ho netefatsa hore e lumellana le litekanyetso tse sebetsang le litekanyetso tse amanang le sehlahisoa.
Litlhokahalo tse akaretsang tsa tlhahlobo ea khatello
1. Bakeng sa li-valve tse entsoeng ka mokhoa o khethehileng tse lumellang hore grease ea ho koala ha tšohanyetso e kenngoe sebakeng sa ho tiisa kapa likarolo tsa ho paka (ntle le li-valve tsa li-plug tse tlotsitsoeng), tsamaiso ea ente e lokela ho ba e se nang letho le e sa sebetseng nakong ea tlhahlobo.
2. Ha u etsa liteko ka mokelikeli, etsa bonnete ba hore moea oa lesoba o tsoa.
3. Pele o etsa tlhahlobo ea khetla ea li-valve, valve ha ea lokela ho penta kapa ho koaheloa ka litlolo leha e le life tse ka patang liphoso tse ka holimo.Phosphating kapa liphekolo tse tšoanang tsa lik'hemik'hale tse sebelisetsoang ho sireletsa bokaholimo ba valve li lumelletsoe, empa ha lia tlameha ho koahela liphoso tse kang ho lutla, masoba a moea kapa machache.
4. Ha ho etsoa liteko tsa ho tiisa holim'a li-valve tsa heke, li-valve tsa plug le li-valve tsa bolo, lesoba la 'mele pakeng tsa bonete le bokaholimo ba ho koala le lokela ho tlatsoa ka sehare.Joale o lokela ho sebelisa khatello ho eona e le hore u leke khatello le ho qoba ho tlatsoa butle-butle ha likarolo tse ka holimo ka seaplane le khatello nakong ea teko, ha u ntse u qoba ho tsoa ha tiiso.
5. Ha u etsa tlhahlobo ea ho tiisa, ha ho matla a ka ntle a lokelang ho sebelisoa lipheletsong leha e le life tsa valve e nang le phello ea ho lutla ha sebaka sa ho tiisa.Torque e sebelisoang ho koala valve ha ea lokela ho feta nako ea ho koala ea matla (torque) ea moralo oa valve.
EC e fana ka lits'ebeletso tsa tlhahlobo ea li-valve tsa litsebi ho pholletsa le China.Ikopanye le rona haeba o hloka ho hlahloba ka nepo boleng ba lihlahisoa tsa hau.
