Kutheni kufuneka iiValve zeBhola ezincinci kwiMarine?

1. Ukusebenza kakuhle kwesithuba

Iindawo zaselwandle ziphawulwa ziindawo ezincinci apho yonke intshi yendawo ekhoyo ixabisekile. Iivalvu zebhola ezincinci zinokufakwa kwiindawo ezixineneyo ngaphandle kokuphazamisa ulwakhiwo lulonke lweenkqubo zenqanawa. Oku kuzenza zilungele iindawo ezinesithuba esincinci, ezinje ngamagumbi eenjini, amagumbi okumpompa, nakwezinye iindawo apho kufuneka khona imibhobho emininzi kunye neepayipi ukuze zihambelane ngokusondeleyo.

2. Ukuthembeka kunye nokuqina

Iivalvu zebhola zaziwa ngokuqina kwazo kunye nobomi bazo obude, nto leyo ebalulekileyo kwimeko enzima yaselwandle. Zisebenza ngendlela elula: ibhola ejikelezayo enemingxuma embindini. Xa umngxuma uhambelana necala lokuhamba, ivalvu ivulekile; xa ijikeleziswa ngokuthe nkqo kumjelo, ivalvu ivaliwe. Le ndlela ithembekile kwaye ayichaphazeleki lula ngenxa yokuguguleka xa ithelekiswa nezinye iintlobo zeevalvu. Ukongeza, iivalvu zebhola ezincinci zinokwenziwa ngezinto ezimelana nokugqwala kunye nokukhula kolwandle, ukuqinisekisa ukuba ziyakwazi ukumelana neemeko ezinzima elwandle.

3. Ulawulo oluKhawulezayo noluchanekileyo

Iivalvu zebhola ezincinci zibonelela ngolawulo olukhawulezileyo noluchanekileyo lokuhamba kolwelo, nto leyo ebalulekileyo kwiindawo ezininzi zaselwandle. Ukukwazi ukuvula okanye ukuvala ngokupheleleyo ivalvu ngokusebenza okulula kokujika ikota kuvumela impendulo ekhawulezileyo ekulawuleni ukuhamba kolwelo olufana namafutha, amanzi, kunye nolwelo lwe-hydraulic. Oku kubaluleke kakhulu kwiimeko zikaxakeka apho ulawulo olukhawulezileyo lokuhamba kolwelo lunokuba lubalulekileyo kukhuseleko lwenqanawa kunye nabasebenzi bayo.

4. Ukuguquguquka kwezinto

Iivalvu zebhola ezincinci zinokuguquguquka kakhulu kwaye zingasetyenziswa kwiindlela ezahlukeneyo zokusetyenziswa elwandle. Zinokuphatha iintlobo ezahlukeneyo zolwelo, kuquka ulwelo, iigesi, kunye ne-slurry, kwaye zinokusebenza phantsi kobushushu obahlukeneyo kunye noxinzelelo. Oku kuzenza zifaneleke ukusetyenziswa kwiinkqubo ezahlukeneyo enqanaweni, ukusuka kwinkqubo ephambili yokuqhuba ukuya kwiinkqubo ezincedisayo ezifana nokupholisa, ukuthambisa, kunye neenkqubo zokulwa nomlilo.

5. Ukugcinwa nokulungiswa

Ukulula koyilo lwevalvu yebhola kwenza kube lula ukuyigcina nokuyilungisa. Xa kukho ukusilela, ivalvu idla ngokuqhekeka ize ilungiswe kwindawo yayo ngezixhobo ezincinci kunye nobuchule. Oku kubalulekile xa kujongwa ukusetyenziswa kwezixhobo zaselwandle apho iindawo zokutshintshwa kunye neenkonzo zokulungisa ezikhethekileyo zisenokungafumaneki lula.

6. Ixabiso eliphantsi

Iivalvu zebhola ezincinci zihlala zibiza kakhulu kunezinye iintlobo zeevalvu, ingakumbi xa kucingelwa ubomi bazo obude kunye neemfuno zolondolozo eziphantsi. Iindleko zokuqala zokufakela ziphantsi kakhulu, kwaye ukonga ngokwemiqathango yokugcinwa okuncitshisiweyo kunye nexesha lokungasebenzi kunokunciphisa iindleko ngaphezu kobomi benkonzo yevalvu.
