Iivalvuazisetyenziswa ngokubanzi kuphela kumashishini ahlukeneyo, kodwa zikwasebenzisa iimeko-bume ezahlukeneyo, kwaye ezinye iivalvu kwiindawo zokusebenza ezirhabaxa ziba neengxaki. Kuba iivalvu zisisixhobo esibalulekileyo, ngakumbi kwezinye iivalvu ezinkulu, kunzima ukuzilungisa okanye ukuzitshintsha xa kukho ingxaki. Ke ngoko, kubaluleke kakhulu ukwenza umsebenzi olungileyo wolondolozo lwemihla ngemihla nololongo. Makhe sijonge iingcebiso malunga nokugcinwa kwevalvu.
1. Ukugcinwa kunye nokuhlolwa kwemihla ngemihla kweiivalve
1. I-valve kufuneka igcinwe kwigumbi elomileyo kunye nelomoya, kwaye zombini iziphelo zepaseji kufuneka zivaliwe.
2. Iivalvuigcinwe ixesha elide kufuneka ihlolwe rhoqo, ukungcola kufuneka kususwe, kunye neoli echasene ne-rust kufuneka ifakwe kwindawo yokucubungula.
3. Emva kofakelo, ukuhlolwa rhoqo kufuneka kwenziwe, kwaye izinto zokuhlola eziphambili zezi:
(1) Ukunxitywa komphezulu wokutywina.
(2) Intambo yetrapezoidal inxiba isiqu kunye ne-stem nut.
(3) Ingaba i-filler iphelelwe yisikhathi kwaye ayisebenzi, ukuba yonakalisiwe, kufuneka itshintshwe ngexesha.
(4) Emva kokuba ivalve igqitywe kwaye idityanisiwe, uvavanyo lokusebenza lokutywina kufuneka lwenziwe.
2. Umsebenzi wogcino xa ivalve iqatywe igrisi
Ulondolozo lobungcali lweivalvengaphambi nangemva kwe-welding kunye nemveliso idlala indima ebalulekileyo kwinkonzo yevalve ekuveliseni nasekusebenzeni, kwaye ukulungiswa okuchanekileyo nokucwangcisiweyo kunye nokugcinwa okusebenzayo kuya kukhusela i-valve, yenza i-valve isebenze ngokuqhelekileyo kwaye yandise ubomi benkonzo yevalve. Ukugcinwa kwevalve kunokubonakala kulula, kodwa akunjalo. Kukho iinkalo ezininzi zomsebenzi ezingahoywayo.
1. Xa i-valve ifakwe igrisi, ingxaki yokutofa igrisi idla ngokungahoywa. Emva kokuba umpu wenaliti yegrisi ugalelwe i-refuel, umsebenzisi ukhetha ivalve kunye nendlela yokudityaniswa kwenaliti yegrisi ukwenza umsebenzi wokutofa kwegrisi. Kukho iimeko ezimbini: kwelinye icala, inani lenaliti yegrisi lincinci, inaliti yegrisi ayanelanga, kwaye umphezulu wokutywina unxitywa ngokukhawuleza ngenxa yokungabikho kwe-lubricant. Kwelinye icala, inaliti yegrisi egqithisileyo ibangela inkcitho. Oku kungenxa yokuba akukho kubalwa ngokuchanekileyo komthamo wokutywina weevalvu ezahlukeneyo ngokohlobo lwesivalo. Umthamo wokutywina unokubalwa ngokobukhulu kunye nohlobo lwevalve, kwaye ke isixa esifanelekileyo segrisi sinokutofwa ngokufanelekileyo.
Okwesibini, xa i-valve ifakwe igrisi, ingxaki yoxinzelelo ihlala ingahoywa. Ngethuba lomsebenzi wokutofa igrisi, uxinzelelo lwenaliti yegrisi lutshintsha rhoqo kwiincopho kunye neentlambo. Uxinzelelo luphantsi kakhulu, ukuvuza kwetywina okanye uxinzelelo lokusilela luphezulu kakhulu, indawo yokutofa igrisi ivaliwe, igrisi eselutywinweni iqinisiwe, okanye iringi yokutywina itshixiwe ngebhola yevalve kunye nepleyiti yevalvu. Ngesiqhelo, xa uxinzelelo lwenaliti yegrisi lusezantsi kakhulu, igrisi etofwayo ikholisa ukuqukuqela ukuya kumazantsi omgodi wevalvu, oyenzeka ngokubanzi kwiivalvu zesango ezincinci. Ukuba uxinzelelo lwenaliti yegrisi luphezulu kakhulu, kwelinye icala, jonga umbhobho wenaliti yegrisi, kwaye uwubuyisele endaweni ukuba umngxuma wegrisi uvalekile; Ngakolunye uhlangothi, ukuqina kwegrisi, apho isisombululo sokucoca sisetyenziselwa ukuthambisa ngokuphindaphindiweyo igrisi yokutywinwa engaphumeleli kwaye ithathe indawo ngegrisi entsha. Ukongeza, uhlobo lokutywina kunye nezinto zokutywina nazo zichaphazela uxinzelelo lwegrisi, iifom zokutywina ezahlukeneyo zinexinzelelo lwegrisi eyahlukileyo, ngokubanzi, uxinzelelo lwegrisi elukhuni luphezulu kunophawu oluthambileyo.
Ukwenza lo msebenzi ungentla kukholelwa ukuba luncedo kakhulu ekwandiseni ubomi benkonzo yeivalve, yaye kwangaxeshanye, kunokunciphisa iingxaki ezininzi ezingeyomfuneko.
