Umsebenzi oyintloko we-valve kukuhlukanisa izixhobo kunye nenkqubo yokubhobhoza, ukulawula ukuhamba, ukuthintela ukubuyela emva, ukulawula kunye nokukhupha uxinzelelo, yinto yokulawula inkqubo yepayipi yamanzi, indima ibaluleke kakhulu.Ngoko ke, ekusetyenzisweni okuqhelekileyo kwenkqubo kufuneka kuhlawulelwe ukugcinwa kwe-valve kunye nokugcinwa.

1. Umsebenzi woLondolozo lweMihla yeValve

1.1 Indawo yokugcina i-valve kufuneka iqatshelwe, kufuneka igcinwe kwigumbi elomileyo lokungenisa umoya, kwaye ivimbe indlela yokuhamba kuzo zombini iziphelo.

1.2 I-valve kufuneka ihlolwe rhoqo, kunye nokususwa kokungcola kumphezulu wayo ofakwe ngeoli echasene ne-rust.

1.3 Emva kokuba i-valve ifakwe kwaye isetyenziswe, iya kulungiswa rhoqo ukuze kuqinisekiswe ukusebenza kwayo okuqhelekileyo.

1.4 Kufuneka atshekishe ukuba ivalve etywina umphezulu iyanxitywa na, nangokungqinelana neemeko zokulungiswa okanye ukutshintshwa.

1.5 Qwalasela i-stem kunye ne-stem nut trapezoidal thread wear, ukupakishwa kuphelelwe yisikhathi kwaye akukho mthethweni, kwaye wenze ukutshintshwa okuyimfuneko.

1.6 Vavanya ukusebenza kokutywinwa kwevalve ukuqinisekisa ukusebenza kwayo.

1.7 Ivalve kufuneka ibekwimeko entle yokusebenza, iibholithi zeflange kunye nezibiyeli ziphelele, imisonto ingaguquki, kungabikho nto ikhululekileyo.

1.8 Ukuba ivili lesandla alikho, maligqitywe kwangethuba kwaye alinakutshintshwa sisipanela.

1.9 Ukupakisha idlala akuvumelekanga ukuba lijike okanye kungabikho msantsa wangaphambili.

1.10 Ukuba ivalve isetyenziswe kwindawo enzima, esengozini yemvula, ikhephu, uthuli, isanti kunye nezinye izinto ezingcolileyo, kufuneka ifake isigqubuthelo sokukhusela isiqu sevalve.

1.11 Irula ekwivalvu kufuneka igcinwe injalo, ichanekile, icace, ivalve lead seal, ikepusi.

1.12 Ijacket ye-insulation kufuneka ingabikho ukudakumba, iintanda.

1.13 Iivalvu ezisebenzayo, kunqande ukuzibetha okanye ukuxhasa imithwalo enzima.

2. Umsebenzi woLondolozo lweFat yeValve

Ukugcinwa kobugcisa kwevalve ngaphambi nangemva kokusebenza kwe-welding kudlala indima ebalulekileyo kwinkonzo yevalve ekuveliseni nasekusebenzeni.Ukugcinwa okufanelekileyo kunye nocwangco kuya kukhusela umsebenzi we-valve ngokufanelekileyo kunye nokwandisa ubomi benkonzo yevalve.Ukugcinwa kweValve kunokubonakala kulula, kodwa akunjalo.Kukho iinkalo ezininzi zomsebenzi ezingahoywayo.

2.1 Isitofu saMafutha eValve, Nika Ingqalelo kwisixa saMafutha.

Emva kokuba uMpu weGrisi uthanjiswe ioyile, umqhubi ukhetha ivalve kunye nemowudi yokudityaniswa kwenaliti yegrisi ukwenza umsebenzi wokutofa igrisi.Kukho iimeko ezimbini: kwelinye icala, inaliti encinci yegrisi ayanelanga, indawo yokutywina ngenxa yokungabikho kwezithambiso kunye nokukhawuleza ukunxiba.Kwelinye icala, inaliti yamafutha agqithisileyo, okukhokelela kwinkcitho.Akukho kubalwa ngokuchanekileyo komthamo wokutywina weevalvu ezahlukeneyo ngokohlobo lwesivalo.Umthamo wokutywina unokubalwa ngokobungakanani bevalve kunye nodidi, kwaye ubungakanani obufanelekileyo begrisi bunokutofwa ngokufanelekileyo.

2.2 I-Valve Fat Injection, kufuneka sinikele ingqalelo kwiNgxaki yoxinzelelo.

Ngethuba lomsebenzi wokutofa, uxinzelelo lwenaliti lutshintsha ngendlela eqhelekileyo.Uxinzelelo luphantsi kakhulu, ukuvuza kwetywina okanye uxinzelelo lokusilela luphezulu kakhulu, isitofu somlomo wamafutha uvalekile, uhlobo lwamafutha angaphakathi luyaqina okanye iringi yokutywina kunye nebhola yevalve, ipleyiti yevalve iyanga ifile.Ngokuqhelekileyo uxinzelelo lwenaliti yegrisi luphantsi kakhulu, ukutofa kwegrisi kumazantsi omqolo wevalvu, ngokuqhelekileyo kwenzeka kwivalve yesango encinane.Uxinzelelo lwenaliti luphezulu kakhulu, kwelinye icala, khangela umbhobho wenaliti, njengokuvaleka komngxuma wegrisi gweba imeko yokutshintshwa;kwelinye icala, ukusetyenziswa kolwelo lokucoca ngokuphindaphindiweyo ukuthamba kokungaphumeleli kwegrisi yokutywina, kunye nesitofu sokutshintshwa kwegrisi entsha.Ukongeza, uhlobo lokutywina kunye nemathiriyeli yokutywina, kodwa ikwachaphazela uxinzelelo lwenaliti, iindlela ezahlukeneyo zokutywina zinoxinzelelo olwahlukileyo lwesitofu, imeko ngokubanzi yoxinzelelo lwenaliti enzima ukuya phezulu kunotywino oluthambileyo.
