Xa isitywina sevalve singaqinile okanye i-sag inkulu kakhulu, ivalve kufuneka isuswe ukuze igcinwe, ilungiswe okanye ifakwe endaweni yayo. Ukususa i-valve, susa kuqala isivalo sentloko ye-cylinder, susa i-valve rocker arm assembly, susa umbhobho we-fuel-pressure, susa i-injector ye-fuel, ukhulule i-cylinder head nut, kwaye ususe intloko ye-cylinder. Emva koko cinezela isihlalo sevalve yasentwasahlobo ngesixhobo esikhethekileyo sokuqhaqha ivalve, cinezela imithombo yangaphakathi nangaphandle yevalve, khupha ikliphu yokutshixa ivalve, emva kokukhulula, susa imithombo yangaphakathi nangaphandle yevalve, emva koko ivalve ingakwazi. kukhutshwa. Emva kokuba i-valve isusiwe, kufuneka imakishwe kwaye kufuneka ingatshintshwa ngexesha lokuhlanganisa. Ukusebenzisa isalathisi sokudayela kunye ne-V-bracket, umlinganiselo we-valve stem flex. Ngexesha lokuhlolwa, i-valve stem ixhaswa kwiifreyimu ezimbini ezinobumba obuno-V kunye nomgama we-100 mm, kwaye emva koko sebenzisa i-dial gauge ukujonga ukuba i-1/2 yobude bevalve yi-curvature. Ukuba idlula umda ovumelekileyo, kufuneka ilungiswe ngokucinezela ngesandla.
Xa ivalve ivuza kancinane, inokucolwa ukuze ibuyisele ukuqina kwayo. Ngaphambi kokusila ivalve, ivalve, isihlalo sevalve kunye netyhubhu yesikhokelo kufuneka icocwe. Ngokukhetha, i-valve head subsidence ye-cylinder nganye kufuneka ihambelane, kwaye amanqaku kufuneka enziwe phezulu kwentloko yevalve ukuphepha ukudideka. Indlela yokugaya ngesandla imi ngolu hlobo lulandelayo:
(1) Beka umthombo othambileyo kwisiqu sevalve, sebenzisa umaleko wesanti yevalve kwithambeka levalve, sebenzisa i-oyile yokuthambisa kwisiqu sevalve, uze ufake isivalo kumbhobho wesikhokelo. Isanti yevalvu yohlulwe ibe ziindidi ezimbini: isanti erhabaxa kunye nesanti ecolekileyo. Ukhetho luxhomekeke kwiqondo lokutshisa i-valve bevel kunye ne-bevel seat bevel. Ukugaya ngokuthe ngqo ivalve esetyenzisiweyo, ungasebenzisa isanti erhabaxa ukugaya kuqala, kwaye usebenzise isanti ecolekileyo ukugaya kakuhle. Ukuba i-valve ye-valve ilungiswa ngokusila ngokugudileyo, isihlalo sevalve silungiswa ngokubuyisela kwakhona, kwaye i-bevel iphelile, inokuculwa kuphela ngesanti ecocekileyo.
(2) Sebenzisa ivalve yokusila iscrewdriver okanye irabha twister ukujikelezisa ivelufa ngasemva naphambili (i-engile yokujikeleza kufuneka ibe ngaphantsi kwe-180 °) ekusileni. Ngethuba lenkqubo yokugaya, ukuphakamisa kunye nokunyanzeliswa kwezenzo kufuneka kwenziwe kunye nomgangatho ojikelezayo we-valve ukutshintsha indawo yokugijima ye-valve kunye nesihlalo sokuqinisekisa ukugaya okufanayo. Xa usila, musa ukusebenzisa amandla agqithisileyo, musa ukuphakamisa ivalve, kwaye ubethe isitulo sevalve ngamandla ukunqanda ukwandisa i-bevel okanye ukugaya i-concave grooves.
(3) Xa isivalo kunye nethambeka lesitulo sevalve zigutyungelwa kwibhanti elipheleleyo neligudileyo lonyaka, oko kuthetha ukuba ukucola kugqityiwe. Isanti ye-valve inokuhlanjwa, kwaye ioli isetyenziswe kwi-slope, kwaye emva kwemizuzu emi-3 ukuya kwemi-5. Ngexesha lokugaya, musa ukusebenzisa isanti yevalvu eninzi kakhulu ukukhusela ilahleko kunye nokuguga kwezinye iindawo zokukhwelana.
(4) Ithambeka lokudibana komhlaba kufuneka libe mpuluswa kwaye licoceke, kwaye ububanzi bokudibanisa ngokuqhelekileyo bu-1. 5 ukuya ku-2. 0 mm. Beka ivalve kwisitulo sevalve ehambelanayo, uze ucofe intloko yevalvu amaxesha amaninzi. Ukuba i-halo eqhubekayo, eqaqambileyo engwevu ibonakala phakathi kwendawo yokusebenza yevalve, oko kuthetha ukuba i-valve idibene ngokuqhelekileyo kunye nesitulo sevalve. Okanye uzobe umgca wepensile othambileyo rhoqo nge-4 mm kwindawo yokusebenza yevalve, emva koko faka ivalve kwisikhokelo sevalve kunye nesihlalo sevalve, vula i-1/8 ukuya ku-1/4 ukujika, okanye ucofe amaxesha ambalwa, ukuba imigca yepensile yonke isembindini webhanti Iphazamisekile, ebonisa ukuba ivalve kunye nesihlalo sevalve zitywinwe kakuhle.
