Iivalvu zebhabhathane zizinto ezibalulekileyo kwizicelo ezahlukeneyo zoshishino. Zinomsebenzi wokuvala ulwelo nokulawula ukuhamba kwamanzi. Ngoko ke ukwazi imeko yeevalvu zebhabhathane ngexesha lokusebenza—nokuba zivuliwe okanye zivaliwe—kubalulekile ekusetyenzisweni nasekugcinweni kakuhle.
Ukufumanisa ukuba ivalvu yebhabhathane ivuliwe okanye ivaliwe kuxhomekeke kakhulu ekubonweni nakwizalathisi. Xa i-actuator ingeyona isiphatho, indlela ipleyiti yevalvu ehamba ngayo phezulu nasezantsi yahlukile kwezinye iivalvu ezifana neevalvu zesango lesiqu esinyukayo kunye neevalvu zeglobe (iivalvu zesango lesiqu esinyukayo zifuna kuphela ukujonga ukuphakama kwesiqu sevalvu ukuze kuchongwe indawo yepleyiti yevalvu). Iivalvu zebhabhathane zinomahluko. Idiski yevalvu inokujikeleza ukusuka kwi-0 ukuya kwi-90° emzimbeni wevalvu ukutshintsha ukuhamba kolwelo.
Nantsi indlela yokuchonga indawo yepleyiti yebhabhathane yevalvu yebhabhathane:
1. Idiski enamazinyo okujonga okubonakalayo:
Iivalvu ezincinci zebhabhathane ezinobubanzi obuyi-DN ≤ 250, zinokuxhotyiswa ngezibambo kunye neediski ezinamazinyo. Njengoko igama lisitsho, idiski enamazinyo ngokubanzi inezikali ezili-10, eyokuqala ivaliwe ngokupheleleyo, kwaye eyokugqibela ivuliwe ngokupheleleyo.
Indawo evulekileyo: Xa ivuliwe ngokupheleleyo, idiski yevalvu ihambelana necala lokuhamba kwamanzi, nto leyo evumela ukuba umjelo wolwelo ungaphazanyiswa.
Indawo evaliweyo: Kwimeko yokuvalwa, idiski yevalvu yenza i-vertical blockage kulwelo kwaye iyeke ukuhamba kolwelo.
2. Isalathisi sendawo:
Iivalvu ezininzi zebhabhathane zixhotyiswe ngezalathisi zangaphandle ezifana neentolo okanye iimpawu entlokweni yeturbine. Ezi zimpawu zihambelana neempawu ezithile ezibonisa indawo yevalvu.
3. Isiginali yempendulo:
Kwiinkqubo eziphambili, imiqondiso yempendulo evela kwiisensa okanye kwiiswitshi idityaniswe kwindlela yokusebenza kwevalvu, nto leyo enika ulwazi ngexesha langempela malunga nemeko yevalvu.
4. Ukubeka esweni okukude:
Ukufakelwa kwemizi-mveliso yanamhlanje kunokusebenzisa iinkqubo zokubeka esweni ezikude ezivumela abaqhubi ukuba bajonge imeko yeevalvu zeebhabhathane bekude kwaye baphucule ulawulo kunye nokubeka esweni.
Ukuqinisekisa ukuba ivalvu yebhabhathane ibekwe kwindawo efanelekileyo kubalulekile ekugcineni ukuthembeka kwenkqubo, ukuthintela ukuvuza kunye nokwenza ngcono ukusebenza kakuhle. Iinkqubo zokuhlola rhoqo kunye nokugcinwa kwazo kufuneka zibandakanye ukuqinisekiswa kwemeko yezi valve ukunciphisa umngcipheko kunye nokugcina ukusebenza kwenkqubo.
Ngamafutshane, ukuchonga ukuba ivalvu yebhabhathane ivuliwe okanye ivaliwe kuxhomekeke kakhulu kwiimpawu ezahlukeneyo ezibonakalayo nezobuchwephesha. Ukuqonda ezi zikhokelo kubalulekile ekulawuleni ngempumelelo iivalvu kunye nemisebenzi yemizi-mveliso.
