Njengenxalenye ebalulekileyo yenkqubo yemizi-mveliso, ukufakelwa ngokuchanekileyo kubalulekile. Ivalvu efakwe ngokufanelekileyo ayiqinisekisi nje kuphela ukuhamba kakuhle kolwelo lwenkqubo, kodwa ikwaqinisekisa ukhuseleko kunye nokuthembeka kokusebenza kwenkqubo. Kwiindawo ezinkulu zemizi-mveliso, ukufakelwa kweevalvu akufuneki nje kuphela ukuqwalaselwa kweenkcukacha zobugcisa, kodwa kunye nokuthobela imigaqo kunye nemigangatho yokhuseleko efanelekileyo. Ke ngoko, ukubaluleka kokufakelwa kweevalvu ngokuchanekileyo akubonakali kuphela ekusebenzeni kakuhle nasekuzinzeni kokusebenza kwenkqubo, kodwa nakukhuseleko lwabasebenzi kunye nezixhobo. Ngokufakelwa ngokuchanekileyo, iingxaki zokuvuza zinokuncitshiswa, ukusebenza kakuhle kwenkqubo kunokuphuculwa, iingozi zemizi-mveliso zinokuphetshwa, okusingqongileyo kunye nobomi babasebenzi kunye nepropathi zinokukhuseleka, ngaloo ndlela kubonelela ngokhuseleko oluthembekileyo kwimveliso yemizi-mveliso. Ke ngoko, ukufakelwa kweevalvu ngokuchanekileyo kubalulekile kwaye yenye yeekhonkco eziphambili ekuqinisekiseni ukusebenza ngokukhuselekileyo kweenkqubo zemizi-mveliso.

1. Ivalvu eguquliweyo.

Iziphumo: ivalvu eguqulweyo, ivalvu yokujika, ivalvu yokunciphisa uxinzelelo, ivalvu yokujonga kunye nezinye iivalvu zibhekisa kwicala, ukuba ivalvu iguqulweyo, ivalvu iya kuchaphazela isiphumo sokusetyenziswa kunye nobomi; Iivalvu zokunciphisa uxinzelelo azisebenzi konke konke, kwaye iivalvu zokujonga zinokuba yingozi.

Imilinganiselo: Iivalvu eziqhelekileyo, ezineempawu zendlela emzimbeni wevalvu; Ukuba akunjalo, kufuneka zichongwe ngokuchanekileyo ngokomgaqo wokusebenza wevalvu. Igumbi levalvu yevalvu yehlabathi alilingani, kwaye ulwelo kufuneka luvunyelwe ukuba ludlule kwizibuko levalvu ukusuka ezantsi ukuya phezulu, ukuze ukumelana nolwelo kube kuncinci (kumiselwe yimo), ukuvulwa konga abasebenzi (ngenxa yoxinzelelo oluphakathi ukuya phezulu), kwaye i-medium ayicinezeli ukupakisha emva kokuvala, okulula ukuyilungisa. Yingakho ivalvu yokumisa ingenakuguqulwa. Musa ukuguqula ivalvu yesango (oko kukuthi, ivili lesandla liyehla), kungenjalo i-medium iya kuhlala kwindawo yokugubungela ivalvu ixesha elide, kulula ukuyigungqa isiqu sevalvu, kwaye ayivumelekanga kwiimfuno ezithile zenkqubo. Akulula kakhulu ukutshintsha ukupakisha ngaxeshanye. Vula ivalvu yesango lesiqu, ungayifaki emhlabeni, kungenjalo ngenxa yokufuma kunye nokugqwala kwesiqu sevalvu esivezwe yingqele. Ivalvu yokujonga yokuphakamisa, ukufaka ukuqinisekisa ukuba idiski yevalvu imile nkqo, ukuze i-lift iguquguquke. Ivalvu yokujonga yokujikeleza, ukufaka ukuqinisekisa ukuba i-pin inqanaba, ukuze i-swing iguquguquke. Ivalvu yokunciphisa uxinzelelo kufuneka ifakwe ime nkqo kumbhobho othe tye, kwaye ungathambeki nakweyiphi na indlela.

2. Ukufakwa kweevalvu ngaphambi kokuba kungenziwa uhlolo lomgangatho olufunekayo.

Iziphumo: Ingakhokelela ekusebenzeni kwenkqubo yeswitshi yevalvu ingaguquguquki, ivalwe ngokukhululekileyo kwaye ukuvuza kwamanzi (igesi) kwenzeke, okubangela ukulungiswa kwakhona, kwaye kuchaphazele nokuhanjiswa kwamanzi okuqhelekileyo (igesi).

Amanyathelo: Ngaphambi kokufakwa kwevalvu, kufuneka kwenziwe uvavanyo lwamandla okuxinwa kunye nokuqina. Uvavanyo kufuneka lwenziwe ngokuthatha isampuli ye-10% yobungakanani bebhetshi nganye (umgangatho ofanayo, iinkcukacha ezifanayo, imodeli efanayo), kwaye kungabi ngaphantsi kweyodwa. Kwiivalvu zesekethe ezivaliweyo ezifakwe kumbhobho oyintloko ezidlala indima yokusika, uvavanyo lwamandla kunye nokuqina kufuneka lwenziwe nganye nganye. Uxinzelelo lovavanyo lwamandla kunye nokuqina kwevalvu kufuneka luhambelane nekhowudi yokwamkelwa komgangatho.

3. I-flange ye-valve yebhabhathane ene-flange ye-valve eqhelekileyo.

Iziphumo: ubungakanani beflange yevalvu yebhabhathane bahlukile kobo beflange yevalvu eqhelekileyo. Ezinye iiflange zinedayamitha ezincinci zangaphakathi, kwaye iflange yevalvu yebhabhathane inkulu, nto leyo ebangela ukuba ivalvu ingavuleki okanye ivuleke nzima.

Imilinganiselo: I-Flange kufuneka icutshungulwe ngokobukhulu bokwenyani be-flange ye-butterfly valve.
