2. Ntlafatsa khetho ea thepa le mehato e thibelang{1}}ho bola
Khetho e loketseng ea lisebelisoa: Ha u reka mabili a matsoho a li-valve tsa heke le li-valve stems, likhoebo li ela hloko khetho ea lisebelisoa. Ho ea ka tikoloho ea ho sebetsa le litšoaneleho tse mahareng, khetha lisebelisoa tse nang le thepa e loketseng ea mochini le ho hanyetsa kutu. Ka mohlala, tikolohong e senyang haholo, tšepe e sa hloekang kapa e senyang{2}}lisebelisoa tse sa tsitsang li khethoa ho etsa mabili a letsoho le likutu tsa valve ho netefatsa botsitso ba likarolo tsa khokahanyo.
Matlafatsa - kalafo ea kutu: Bakeng sa li-valve tsa heke tse sebetsang tikolohong e thata, ho nkoa mehato e sebetsang ea ho thibela ho bola. Ka mohlala, ho chesa-dip galvanizing le ho fafatsa ka-anti-corrosion coatings likarolong tsa khokahanyo ho ka etsa filimi e sireletsang ho thibela mokhoa o senyang ho senya thepa. Ka nako e ts'oanang, litlolo tse thibelang ho bola{6}li lokela ho hlahlojoa le ho hlokomeloa khafetsa, le likarolo tse senyehileng li lokisoe ka nako. .

Theha mokhoa oa kamehla oa tlhahlobo: Khoebo e tla theha le ho ntlafatsa mokhoa oa kamehla oa tlhahlobo ea li-valve tsa heke, le ho hlakisa potoloho ea tlhahlobo, litaba tsa tlhahlobo le batho ba ikarabellang. Nakong ea ts'ebetso ea tlhahlobo, bahlahlobi ba tla tsepamisa maikutlo ho hokahaneng pakeng tsa lebili la letsoho la valve ea heke le kutu ea valve, 'me hang-hang ba fumane mathata a kang ho hlepha le ho bola,' me ba tlalehe le ho sebetsana le 'ona. .
Emisa mokhoa oa ho tlotsa le oa tlhokomelo: etsa mokhoa o qaqileng oa ho tlotsa le ho lokisa li-valve tsa heke, hlalosa potoloho ea lubrication, mofuta le boholo ba mafura. Basebelisi ba tla lula ba tlotsa le ho boloka khokahano lipakeng tsa lebili la letsoho le kutu ea valve ho latela litlhoko tsa ts'ebetso ho netefatsa ts'ebetso e tloaelehileng ea khokahano.
Bothata ba khokahano e hlephileng pakeng tsaheke valve handwheelle valve stem e fetohile ntho ea bohlokoa e amang polokeho le katleho ea tlhahiso ea indasteri. Ka boiteko bo kopanetsoeng ba lihlopha tsohle tsa indasteri, mehato e sebetsang hantle e tla nkoa likarolong tse ngata tse kang litlhaloso tsa ho kenya, khetho ea thepa, tlhokomelo, joalo-joalo, 'me ho lebeletsoe ho rarolla bothata bona butle-butle. Sena se tla fana ka tiisetso e matla bakeng sa ts'ebetso e tsitsitseng ea tlhahiso ea indasteri le ho khothaletsa nts'etsopele e tsitsitseng le e phetseng hantle ea indasteri.
