Iivalvu azisetyenziswanga kuphela kumashishini ahlukeneyo, kodwa zikwasetyenziswa kwiindawo ezahlukeneyo.Ezinye iivalvu kwiindawo zokusebenza ezirhabaxa ziyakwazi ukuba neengxaki.Kuba ivalve isisixhobo esibalulekileyo, ngakumbi kwezinye iivalvu ezinkulu, kunzima ukuyilungisa okanye ukuyitshintsha xa kukho ingxaki.Ngoko ke, kubaluleke kakhulu ukwenza ukugcinwa kunye nokugcinwa kwemihla ngemihla.Makhe sijonge ulwazi oluncinci malunga nokugcinwa kwevalvu.
A. Ukugcinwa kunye nokuhlolwa kwemihla ngemihla kweevalvu
1. I-valve kufuneka igcinwe kwigumbi elomileyo kunye nelomoya, kwaye zombini iziphelo zepaseji kufuneka zivaliwe.
2. Iivalve ezigcinwe ixesha elide kufuneka zihlolwe rhoqo, ukungcola kufuneka kususwe, kwaye ioli echasene ne-rust kufuneka isetyenziswe kwindawo yokucubungula.
3. Emva kokufakela, ukuhlolwa rhoqo kufuneka kwenziwe.Izinto eziphambili zokuhlola:
(1) Ukunxitywa komphezulu wokutywina.
(2) Ukunxitywa kwentambo yetrapezoidal yesiqu kunye ne-stem nut.
(3) Ingaba ukupakisha kuphelelwe yisikhathi kwaye akuvumelekile, ukuba konakaliswe, kufuneka kutshintshwe ngexesha.
(4) Emva kokuba ivalve ilungisiwe kwaye idityanisiwe, uvavanyo lomsebenzi wokutywina kufuneka lwenziwe.
B. Umsebenzi wokulondoloza ngexesha lokutofa kwegrisi yevalvu
Ukugcinwa kobungcali kwevalve ngaphambi nangemva kwe-welding kudlala indima ebalulekileyo ekukhonzeni ukuveliswa kunye nokusebenza kwevalve.Ukulungiswa okuchanekileyo, okucwangcisiweyo kunye nokusebenzayo kuya kukhusela i-valve, yenza i-valve isebenze ngokuqhelekileyo kwaye yandise ubomi benkonzo yevalve.ubomi.Umsebenzi wokugcinwa kwevalve unokubonakala ulula, kodwa akunjalo.Kukho iinkalo ezininzi zomsebenzi ezingahoywayo.
1. Xa utofa igrisi kwivalve, ubungakanani benaliti yegrisi idla ngokungahoywa.Emva kokuba umpu wenaliti yegrisi ufakwe i-refueled, umqhubi ukhetha ivalve kunye nendlela yokudityaniswa kwenaliti yegrisi, aze enze umsebenzi wokutofa igrisi.Kukho iimeko ezimbini: kwelinye icala, inani lenaliti yegrisi lincinci kwaye inaliti yegrisi ayanelanga, kwaye umphezulu wokutywina unxiba ngokukhawuleza ngenxa yokungabikho kwe-lubricant.Kwelinye icala, isitofu segrisi esigqithisileyo sikhokelela kwinkcitho.Isizathu kukuba akukho kubalwa ngokuthe ngqo komthamo wokutywina wevalve eyahlukileyo ngokodidi lwesivalo.Umthamo wokutywina unokubalwa ngokobungakanani bevalve kunye nohlobo, kwaye ke isixa esifanelekileyo segrisi sinokutofwa.
2. Xa i-valve ifakwe igrisi, ingxaki yoxinzelelo ihlala ingahoywa.Ngethuba lomsebenzi wokutofa igrisi, uxinzelelo lwenaliti yegrisi lutshintsha rhoqo ngeencopho kunye neentlambo.Uxinzelelo lusezantsi kakhulu, ukuvuza kwetywina okanye uxinzelelo lokusilela luphezulu kakhulu, indawo yokutofa igrisi ivaliwe, igrisi yokutywina yangaphakathi yenziwe lukhuni, okanye iringi yokutywina itshixiwe ngebhola yevalve kunye nepleyiti yevalvu.Ngesiqhelo, xa uxinzelelo lwenaliti yegrisi lusezantsi kakhulu, igrisi etofwayo ikholisa ukuqukuqela ukuya kumazantsi omgodi wevalvu, oqhele ukwenzeka kwiivalvu zesango ezincinci.Ukuba uxinzelelo lwenaliti yegrisi luphezulu kakhulu, kwelinye icala, jonga umbhobho wenaliti yegrisi, kwaye uwubuyisele ukuba umngxuma wegrisi uvalekile..Ukongeza, uhlobo lokutywina kunye nezinto zokutywina nazo zichaphazela uxinzelelo lwenaliti yegrisi.Iindlela zokutywina ezahlukeneyo zineexinzelelo ezahlukeneyo zokutofa igrisi.Ngokubanzi, uxinzelelo lwenaliti yegrisi yamatywina aqinileyo luphezulu kunolo lwamatywina athambileyo.
Ukwenza lo msebenzi ungentla kukholelwa ukuba luncedo kakhulu ekwandiseni ubomi benkonzo yevalve, kwaye kwangaxeshanye, kunokunciphisa iingxaki ezininzi ezingeyomfuneko.
