Eyesibini, umsebenzi wokulondoloza igrisi yevalvu
Ukugcinwa kobuchule kweevalvu ngaphambi nangemva kokuveliswa kwe-welding kudlala indima ebalulekileyo kwimveliso kunye nokusebenza kweevalvu. Ukulungiswa okuchanekileyo kunye nokucwangciswayo kunye nokugcinwa okusebenzayo kuya kukhusela iivalve, zenze ukuba zisebenze ngokuqhelekileyo kwaye zandise ubomi benkonzo yee-valve. Ukugcinwa kweValve kubonakala kulula, kodwa akunjalo. Kukho iinkalo ezininzi zomsebenzi ezingahoywayo.
***, igrisi yevalve, ihlala ingahoyi ubungakanani bamafutha.
Emva kwesitofu segrisi kunye nokufaka i-refueling, umqhubi ukhetha ivalve kunye nemo yodibaniso lwenaliti yegrisi ukwenza umsebenzi wokutofa igrisi. Kukho iimeko ezimbini: kwelinye icala, inaliti encinci yamafutha ayonelanga, kwaye indawo yokutywina ikhawuleza ngenxa yokungabikho kwe-lubricant. Kwelinye icala, inaliti yamafutha agqithisileyo, okukhokelela kwinkcitho. Akukho lubalo luchanekileyo lweendlela ezahlukeneyo zokutywina zevalve ngokusekelwe kuhlobo lwevalvu kunye nodidi. Umthamo wokutywina unokubalwa ngobungakanani bevalvu kunye nohlobo, kunye nenaliti efanelekileyo yegrisi efanelekileyo.
Okwesibini, igrisi yevalve, ihlala ingayihoyi ingxaki yoxinzelelo.
Ngexesha lokusebenza kwenaliti ye-fat, uxinzelelo lwenaliti yamafutha lubonise incopho eqhelekileyo kunye notshintsho lwentlambo.
