Iivalvuzizixhobo eziyimfuneko kwimveliso yemizi-mveliso, kwaye ukusebenza kwazo kuchaphazela ngqo uzinzo kunye nokusebenza kakuhle kwenkqubo yokuvelisa. Rhoqoivalveuvavanyo lunokufumana kunye nokusombulula iingxaki zevalve ngexesha, qinisekisa ukusebenza okuqhelekileyo kweivalve, kunye nokuphucula ukusebenza kakuhle kwemveliso.
Okokuqala, ukubaluleka kovavanyo lokusebenza kwevalve
1. Qinisekisa ukhuseleko nokuthembeka:Iivalvungamacandelo olawulo oluyimfuneko kwimibhobho yolwelo neyerhasi, kwaye zenza imisebenzi ebalulekileyo ekulawuleni ukuhamba kwamanzi, uxinzelelo kunye necala. Ngenxa yempembelelo yezinto ezifana nenkqubo yokuvelisa, izinto kunye noyilo, kukho imingcipheko ethile ekusetyenzisweni kweevalve, njengokutywinwa okungahambi kakuhle, amandla angonelanga, ukuxhathisa ukonakala kwe-corrosion, njl. Ngokuvavanya ukusebenza, kunokuqinisekiswa ukuba i-valve inokumelana neemfuno zoxinzelelo kumgca we-fluid, kwaye ugweme ukuvuza, ukungcola, iingozi kunye nezinye iingxaki ezibangelwa ukutywinwa okungahambi kakuhle, ukwenzela ukuba kuqinisekiswe ukusebenza okukhuselekileyo nokuthembekileyo kwenkqubo.
2. Ukuphucula umgangatho wemveliso kunye nokukhuphisana kwemarike: Imigangatho yokuvavanya ukusebenza okungqongqo sisiseko sokuqinisekisa umgangatho weemveliso zevalvu yezoshishino. Ngoluhlu lweenkqubo zokuvavanya, iingxaki ezinokuthi zifumaneke kwaye zisonjululwe, kwaye ukukhuphisana kwemarike yeemveliso kunokwandiswa. Imigangatho ephezulu yovavanyo ikwaqinisekisa ukubaivalveihlangabezana noluhlu olubanzi lweemeko zokusebenza ezifunwayo, ezifana nomthamo woxinzelelo kwiindawo eziphezulu zoxinzelelo, ukutywinwa kokusebenza kwimeko evaliweyo, kunye nokutshintsha okuguquguqukayo nokuthembekileyo.
3. Ukugcinwa kokuthintela kunye nobomi benkonzo eyandisiweyo: uvavanyo lwentsebenzo lunokuvavanya ubomi benkonzo kunye nokuthembeka kwevalve, ukuqikelela ubomi bayo kunye nezinga lokungaphumeleli kwinkqubo yenkonzo, kunye nokubonelela ngereferensi yokugcina. Ngokuhlola rhoqo kunye nokugcinwa, unokwandisa ubomi beevalve zakho kunye nokunciphisa ukuphazamiseka kwemveliso kunye neendleko zokulungisa ngenxa yokungaphumeleli kwevalve.
4. Ukuthobela imigangatho kunye neemfuno zolawulo: Uvavanyo lwentsebenzo yevalve kufuneka luhambelane nemigangatho efanelekileyo yamazwe ngamazwe neyasekhaya ukuqinisekisa ukuba iimveliso zihlangabezana neemfuno zokhuseleko kunye nomgangatho. Ukuthobela umgangatho akuncedi kuphela ukuba imveliso iqinisekiswe, kodwa iphinda izuze ukuthembela ngakumbi kunye nokuqatshelwa kwimarike.
