Kwiindawo zaselwandle, ukukhetha ivalve efanelekileyo kubalulekile kulawulo olululo lwamanzi kunye nokuqinisekisa ukhuseleko kunye nobomi obude beenkqubo zeenqanawa. Iindidi ezimbini ezisetyenziswa ngokuqhelekileyo kwiivalvu kwizicelo zaselwandle ziiivalve zesangokwayeiivalvu zeglowubhu. Ngelixa zombini ziyilelwe ukulawula ukuhamba kolwelo kunye neegesi, zisebenza ngeenjongo ezahlukeneyo kwaye zisebenza ngeendlela ezahlukeneyo. Ukuqonda ukungafani kwabo kunokunceda abaqhubi beenqanawa benze izigqibo ezinolwazi, baqinisekise ukusebenza kakuhle kwiimeko ezinzima.
1. Uyilo kunye nokusebenza
Ivalve yeSango:
- Ivalve yesango isebenza ngokunyusa okanye ukuthoba isango (okanye iwedge) ngaphakathi kumzimba wevalvu ukuqalisa okanye ukumisa ukuhamba.
- Inika ukuhamba okungathintekiyo xa ivuleke ngokupheleleyo, inciphisa ilahleko yoxinzelelo.
- Ifanelene kakhulu kwindawo evuleke ngokupheleleyo okanye evalwe ngokupheleleyo kwaye ayilunganga ukungqusha.
- Iiyantlukwano zoyilo ziquka isiqu esinyukayo kunye neentlobo zesikhondo ezinganyukiyo.
Ivalve yeglowubhu:
- Ivalve yokumisa isebenzisa idiskhi ehamba ngokuchasene nendlela yokuhamba ukuze ilawule okanye imise ulwelo.
- Uyilo lwevalvu luvumela ulawulo olucokisekileyo kunye ne-throttling of flow.
- Ulwakhiwo lwaso lubandakanya isiqu esihamba ngokuthe ngqo kwisihlalo.
- Ibonelela ngokutywinwa ngcono kunye nolawulo lokuhamba, kodwa iziphumo zokuhla koxinzelelo oluphezulu.
2. Izicelo kwiiNkqubo zaseLwandle
Usetyenziso lweGalufa yeSango:
- Ilungele iinkqubo ezifuna ilahleko encinci yoxinzelelo, njengokuthatha amanzi olwandle, amanzi e-ballast, kunye neenkqubo zamafutha.
- Isetyenziselwa ukwahlula amacandelo emibhobho.
- Ifanele ukuphatha umthamo omkhulu wolwelo kunye nezithintelo ezincinci.
Izicelo zeGlobe Valve:
- Ixhaphakile kwiinkqubo ezifuna ukulawulwa kokuhamba okuchanekileyo, okufana neentambo zamanzi zokupholisa, iinkqubo zeoyile yokuthambisa, kunye nokusetyenziswa komphunga.
- Isetyenziswe kwiimeko apho i-throttling okanye uhlengahlengiso lokuhamba kancinci luyimfuneko.
- Idla ngokuqeshwa kwiinkqubo ze-bilge kunye ne-ballast apho kufuneka ulawulo oluhle.
3. Izinto eziluncedo nezingeloncedo
Izinto eziluncedo kwiValuvu yeSango:
- Ukuchasana nokuhamba okuncinci xa kuvuleke ngokupheleleyo.
- Ukwakhiwa okulula kunye nokugcinwa okuphantsi.
- Ihlala kwaye ifanelekile kwiindawo ezinoxinzelelo oluphezulu.
Iintsilelo zeVavu yeSango:
- Ayifanelekanga ukuxinga; ukuvulwa ngokuyinxenye kunokubangela ukhukuliseko kunye nomonakalo.
- Ukusebenza kancinci xa kuthelekiswa neevalvu zokumisa.
Izinto eziluncedo kwiValve yeGlobhu:
- Ulawulo lokuqukuqela oluchanekileyo kunye nezakhono zokuxinana.
- Ibonelela ngokutywinwa ngokuqinileyo, ukunciphisa imingcipheko yokuvuza.
- Isebenza ngokufanelekileyo phantsi kweemeko ezahlukeneyo zoxinzelelo.
Iingxaki zeGlobe Valve:
- Uxinzelelo oluphezulu lwehla ngenxa yoyilo.
- Ulwakhiwo oluntsonkothileyo ngakumbi, olukhokelela ekunyukeni kweemfuno zolondolozo.
4. Ukuchasa ukuRhakala kunye nokuKhethwa kwezinto eziphathekayo
Zombini iivalvu zesango kunye neGlobe ezisetyenziswa kusetyenziso lwaselwandle ngokwesiqhelo zenziwe ngezinto ezixhathisa ukubola, ezifana nezi:
- Ubhedu-Eqhelekileyo kwizicelo zamanzi olwandle.
- Yenziwe ngentsimbi eshayinayo-Ibonelela ngokumelana nokugqwesa okugqwesileyo kunye namandla.
- Cast Intsimbi kunye Epoxy Coating-Isetyenziswe kwiinkqubo ezingabalulekanga kakhulu ukulinganisa iindleko kunye nokuqina.
Ukukhethwa kwezinto ezifanelekileyo kubalulekile ukumelana nemekobume enzima yaselwandle, ukuqinisekisa ixesha elide kunye nokunciphisa iindleko zokulondoloza.
5. Iingqwalasela eziphambili kubaSebenzi baseLwandle
- Iimfuno zokuhamba:Ukuba ilahleko yoxinzelelo oluncinci ibalulekile, iivalve zesango zikhethwa.
- Iimfuno zokuthoba:Ukulawula ukuhamba okuchanekileyo, iivalve zokumisa zibonelela ngokusebenza okungcono.
- UFikelelo kuLondolozo:Iivalvu zokumisa zinokufuna ukulungiswa rhoqo kodwa zinikeze ukutywinwa okungcono.
- Uyilo lweNkqubo:Qwalasela isithuba kunye nokuqhelaniswa nemibhobho xa ukhetha phakathi kwesiqu esinyukayo okanye iivalvu zesango lesikhondo esinganyukiyo.
