Kaha li-valve li ne li ntse li sebetsa hantle tšebeletsong ena, ho ile ha boela ha khothaletsoa hore li sebelisoe lits'ebetsong tse ling tsa hash indastering ea lik'hemik'hale le petrochemical. Kaha li-valve li ntse li sebetsa hantle tšebeletsong ena, ho ile ha boela ha khothaletsoa hore li sebelisoe lits'ebetsong tse ling tsa hash indastering ea lik'hemik'hale le petrochemical.

MOLAO-MOTHEO OA HO BULA LE HO KWALA HAvalve ea polaka e phahamisang
Ho koaloa ha valve:
- 1) retelehela lever ea mohele ka likhato tse 90 ho etsa hore kanale ea plug e otlolohe ho ea ho kanale ea 'mele oa valve
- 2) ebe o retelehela lebili la letsoho ho theola polaka, e le hore valve e koalehe.
Nakong ea ho buloa le ho koaloa ha valve, polaka e phahamisoa 'me e aroloa setulong sa valve, kahoo torque ea ts'ebetso e nyane haholo, ho bonolo haholo ho e bula le ho e koala. 'Me bokaholimo ba ho koala ha bo na ho ngoapa nakong ea ts'ebetso ea ho bula kapa ea ho koala. Kahoo valve e na le bophelo bo bolelele. Valve ea polaka ea mofuta oa ho phahamisa mohele oa letsoho e na le sebopeho se kopaneng, bophahamo bo bonyenyane le khanyetso e tlase ea mokelikeli.
