Yintoni iphedi yokuvala ivalve yemoto
Isivalo segumbi levalve yemoto, ekwabizwa ngokuba yi-valve chamber cover pad, yinxalenye ebalulekileyo yokutywina ngaphakathi enjinini. Ibekwe kwisigqubuthelo segumbi levalve, kwaye umsebenzi wayo ophambili kukuthintela igesi kunye nesipholisi esikwigumbi lokutsha ukuba singangeni kwikhrankcase kwaye siqinisekise ukuqina kwenjini ngaphakathi. I-valve yegumbi lokugquma i-gasket idla ngokwenziwa ngerabha, ino-elasticity elungileyo kunye nokunganyangeki, inokusebenza kumaqondo obushushu aphezulu, uxinzelelo oluphezulu kunye ne-oyile kunye nerhasi enomhlwa.
I-valve cover pad iphantsi koxinzelelo olukhulu kunye nokubola ngexesha lokusebenza kwe-injini, ngoko kufuneka ihlolwe kwaye itshintshwe rhoqo ukuze kuqinisekiswe ukusebenza okuqhelekileyo kunye nokusebenza kwe-injini. Ngokunyuka kwexesha lokusetyenziswa, i-pad ye-valve ye-cover cover ingabonakala iguga, ilukhuni, i-deformation kunye nezinye iingxaki, ezikhokelela ekunciphiseni ukutywinwa kokusebenza, okuchaphazela ukusebenza okuqhelekileyo kwe-injini. Ke ngoko, umnini kufuneka ajonge kwaye atshintshe indawo yesigqubuthelo segumbi levalvu njengenxalenye ebalulekileyo yokugcinwa kwenjini.
Izinto eziphathekayo ze-valve ye-cover cover pad nazo zichaphazela ubomi bayo benkonzo. Kukho izinto ezimbini eziphambili kwiimarike: irabha kunye nezixhobo ezidibeneyo. Iphepha lokuvala ivalve yerabha lixhaphakile, kodwa kulula ukuguga. Ipadi yesigqubuthelo segumbi levalve edibeneyo inokuqina okungcono kunye nokumelana nokunxiba. Umnini kufuneka akhethe imathiriyeli efanelekileyo ngokosetyenziso oluthile lwesithuthi kunye nesindululo somenzi sokwandisa ubomi baso benkonzo.
Umsebenzi ophambili wegumbi levalve yesigqubuthelo segumbi (i-valve yesigubungelo segumbi) kukuqinisekisa ukuqina kwegumbi levalve kunye nokuthintela ukuvuza kweoyile. Idityaniswe nentloko yesilinda kunye nesigqubuthelo somatshini wevalve phezulu ukuze kuqinisekiswe ukusebenza kakuhle kunye nokuthanjiswa okupheleleyo kwesakhiwo sevalvu ye-injini, ngelixa idlala indima ebalulekileyo ekuthinteleni uthuli kunye nokutywinwa.
Iipadi zokugquma igumbi levalvu zihlala zenziwe ngerabha kwaye zinokuqina ngenxa yobudala emva kokusetyenziswa ixesha elide, okukhokelela ekuvuzeni kwe-oyile. Ukongeza, uxinzelelo lwe-screw olungalinganiyo, uxinzelelo olugqithisekileyo lwe-screw, i-valve cover gasket deformation, i-crankcase inyanzeliswa ukuvaleka kwevalve yokungena umoya, umsesane wokutywina okanye iingxaki zomgangatho we-sealant kunokukhokelela kwi-oyile ye-valve ye-gasket.
I-oyile evuzayo inokucudiswa kwisigqubuthelo segumbi levalvu, ivalele indlela ye-oyile kwaye ichaphazele ukusebenza okuqhelekileyo kwe-injini. Ukuvuza kwe-oyile ixesha elide kuya kukhokelela ekunqongophelweni kokuthanjiswa kweoyile kwiindawo zangaphakathi ze-injini, ukuguga ngakumbi, kwaye kunokukhokelela ekulahlekeni kwe-injini kwiimeko ezimandundu.
Ngoko ke, xa i-gasket yegumbi le-valve ifunyenwe i-oyile evuzayo, i-gasket kufuneka itshintshwe kwangethuba ukusombulula ingxaki yokuvuza kwe-oyile, ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini kunye nokwandisa ubomi benkonzo.
