Okwesithathu, xa i-valve igcoba, nikela ingqalelo kwi-valve kwindawo yokutshintsha. Ukugcinwa kwevalve yebhola ngokuqhelekileyo kwindawo evulekileyo, iimeko ezikhethekileyo zikhetha ukugcinwa okuvaliweyo. Ezinye iivalvu azinakunyangwa kwindawo evulekileyo. Ivalve yesango kufuneka ibekwimeko evaliweyo xa ilungiswa, ukuqinisekisa ukuba igrisi ecaleni kweringi yokutywina igqunywe ngegroove yokutywina, ukuba ivulekile, igrisi yokutywina iya kuwela ngqo kumjelo wokuhamba okanye kwigumbi levalve, okukhokelela kugqithiso.

Okwesine, igrisi yevalve, ihlala ingayihoyi ingxaki yefuthe legrisi. Uxinzelelo, ubungakanani begrisi kunye nendawo yokutshintsha kumsebenzi wokutofa igrisi yinto eqhelekileyo. Nangona kunjalo, ukwenzela ukuba kuqinisekiswe i-valve grease effect, ngamanye amaxesha kuyimfuneko ukuvula okanye ukuvala i-valve, khangela i-lubrication effect, kwaye uqinisekise ukuthambisa okuphakathi kwebhola yevalve okanye umphezulu wenkunzi yegusha.

Okwesihlanu, igrisi, kufuneka inike ingqwalasela kwi-valve body blowdown kunye neengxaki zoxinzelelo locingo lokuplaga. Emva kovavanyo loxinzelelo lwevalve, igesi kunye namanzi kwigumbi levalve yegumbi lokutywina liya kwandisa uxinzelelo ngenxa yokunyuka kobushushu bendawo. Ngexesha lenaliti yegrisi, ukunyanzeliswa koxinzelelo kufuneka kuphuculwe ukuze kube lula ukujongwa kwegrisi egudileyo. Emva kwesitofu segrisi, umoya kunye namanzi kwindawo yokutywina zitshintshwa ngokupheleleyo. Ukukhutshwa ngexesha loxinzelelo lwegumbi levalve, kodwa kunye nokuqinisekisa ukhuseleko lokusetyenziswa kwevalvu. Emva kwenaliti yegrisi, qiniseka ukuba uqinise iplagi yocingo yokuvuthela kunye noxinzelelo lokuthintela iingozi.

Okwesithandathu, inaliti yamafutha, kufuneka sinikele ingqalelo kwingxaki yomlinganiselo wamafutha. Ngexesha lokutofa okuqhelekileyo kwamafutha, umngxuma wamanqatha kufutshane nomlomo wokutofa ngamanqatha ngowokuqala ukuvelisa amanqatha, kuze ke ukuya kuthi ga kwinqanaba eliphantsi, i-*** yindawo ephezulu, kwaye amanqatha aveliswa ngokulandelelanayo. Ukuba akunjalo ngokomgaqo okanye hayi amanqatha, kuqinisekiswa ukuba kukho ukuvaleka, unyango lokucocwa ngexesha elifanelekileyo.

Okwesixhenxe, igrisi kufuneka iqwalasele idiameter yevalvu kunye nengxaki yokugungxulwa komsesane wokutywina. Ngokomzekelo, i-valve yebhola, ukuba kukho ukuphazamiseka okuvulekileyo, kunokulungelelaniswa kwi-limiter evulekileyo, qinisekisa ububanzi obuchanekileyo emva kokuvala. Lungisa umda kungekuphela nje ukufuna indawo evulekileyo okanye evaliweyo yecala, ukuqwalasela yonke into. Ukuba indawo yokuvula i-flush kwaye ayivalwanga endaweni, iya kubangela ukuba i-valve ivalwe ngokukhululekileyo. Ngokufanayo, lungisa i-close in place, kodwa uphinde uqwalasele ukulungiswa okuhambelanayo kwendawo evulekileyo. Qinisekisa ukuba ivalve ine-engile echanekileyo.

Okwesibhozo, emva kokutofa ngamanqatha, qiniseka ukuba uyawuvala umlomo wenaliti yamafutha. Kuphephe ukungena kokungcola okanye i-lipid oxidation emlonyeni wenaliti yegrisi. Isigqubuthelo kufuneka sigqunywe ngegrisi echasayo ukurusa ukuthintela umhlwa. Kuqhinga olulandelayo.

Okwesithoba, inaliti yamafutha, kodwa kwakhona ukuqwalasela kwikamva lokuhanjiswa kweoli ngokulandelelana kwezihloko ezineenkcukacha. Ukunikezelwa kweempawu ezahlukeneyo zedizili kunye nepetroli, amandla okugungxulwa kunye nokubola kwepetroli kufuneka aqwalaselwe. Kwixesha elizayo, xa i-valve iqhutywe kwaye icandelo lepetroli lidibene, igrisi kufuneka yongezwe ngexesha lokuthintela ukugqoka kunye nokukrazula.

Okweshumi, xa inaliti ye-fat, ungayihoyi i-fat injection ye-valve stem. Inxalenye ye-valve shaft ine-sleeve ye-sliding shaft okanye ukupakisha, nayo idinga ukugcina i-lubrication, ukwenzela ukunciphisa ukuchasana kwe-friction ngexesha lokusebenza, ukuba ayinakuqinisekisa ukuthambisa, i-torque yokulawula i-torque yokwandisa iinxalenye zokugqoka, umzamo wokutshintsha ulawulo lwe-manual.

Ishumi elinanye, omnye umzimba wevalvu yebhola ephawulwe ngeentolo, ukuba akukho mbhalo wesandla we-FIOW wesiNgesi, wesalathiso sesihlalo sokutywina, hayi njengereferensi ephakathi, isalathiso sevalve yokuzikhupha. Ngokuqhelekileyo, iivalvu zebhola ezitywiniweyo ezinezihlalo ezibini zineendlela ezimbini zokuhamba.

Ishumi elinesibini, ukugcinwa kwevalve, kodwa kwakhona ingqalelo kwintloko yombane kunye nokuhanjiswa kwayo kweengxaki zamanzi. Imvula engena kakhulu ngexesha leemvula. Enye kukurusa isakhiwo semoto okanye umkhono weshaft wothumelo, kwaye omnye kukukhenkceza ebusika. Isizathu sokuba i-torque yokusebenza kwevalve yombane inkulu kakhulu, umonakalo owenziweyo uya kwenza ukuba i-motor ingabi namthwalo okanye i-super torque yokukhusela ixhuma ayikwazi ukufikelela kulawulo lombane. Iyunithi yokuhambisa yonakalisiwe kwaye ulawulo lwezandla alunakwenzeka. Emva kwesenzo sokukhusela i-torque ephezulu, ulawulo lwe-manual alukwazi ukutshintshela, njengokulawula ukunyanzeliswa, luya kulimaza iindawo zangaphakathi ze-alloy.

I-torque yefriction incinci kwaye umahluko wokubuya uncinci.
