Kwimisebenzi yaselwandle, iivalvu zebronze zihlala zithathwa njengezingcono kuneevalvu zebronze ngenxa yokumelana kwazo nokugqwala okuphuculweyo kunye nokuqina kwazo kwiindawo ezimanzi anetyuwa.
Izizathu Eziphambili Zokuba Kutheni Iivalvu ZeBronze Zingcono Ukusetyenziswa Emanzini
1. Ukumelana nokugqwala okuphezulu
Iindawo zaselwandle zidume ngokuba ne-corrosion ngenxa yokuchatshazelwa rhoqo ngamanzi anetyuwa. Iivalvu zebronze ziyakwazi ukumelana nokugqwala kwamanzi anetyuwa, i-oxidation, kunye ne-pitting, nto leyo eyandisa ubomi bazo. Oku kungenxa yokuba ibronze yenziwe nge-copper kunye ne-tin, indibaniselwano ekwaziyo ukumelana nokugqwala ngokwemvelo.
Kwelinye icala, iivalvu zebrass zinezinc, nto leyo eyenza zibe sesichengeni sokususwa kwezinc. Le nkqubo yenzeka xa i-zinc ikhutshiwe kwi-alloy, ishiya ubhedu olunemingxuma nolubuthathaka olunokuqhekeka lula xa lucinezelwe.
2. Amandla Anyukileyo Nokuqina
Iivalvu zebronze zaziwa ngamandla azo oomatshini kunye nokuqina, nto leyo eyenza ukuba zilungele ukusetyenziswa kwiinqanawa ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu. Ubuchule bazo bokumelana neemeko ezinzima buqinisekisa ukuba zisebenza ngokuthembekileyo ngokuhamba kwexesha.
Ngokwahlukileyo koko, iivalvu zebrass zithambile kwaye zinobunzima bokugoba okanye ukuqhekeka phantsi koxinzelelo oluphezulu, nto leyo eyenza zingathembeki kangako kwiinkqubo ezibalulekileyo ezifana nokupholisa injini okanye iinkqubo zamanzi ezisebenza nge-ballast.
3. Ukususwa kwe-zincification kunye noBuchule bezinto eziphathekayo
Enye yezona ngozi zinkulu zokusebenzisa ithusi kwiindawo zaselwandle kukucinywa kwe-zinc, okunokubangela ukungasebenzi kakuhle kweevalvu kunye nokuvuza. Iivalvu zebronze azichaphazeleki yile ngxaki, nto leyo eyenza ukuba zibe lukhetho olukhuselekileyo noluhlala ixesha elide kwiinkqubo ezibalulekileyo.
Iivalvu zebrass zingafaneleka kwiintambo zamanzi acocekileyo okanye usetyenziso olungenaxinzelelo, kodwa kwiipayipi zamanzi anetyuwa okanye kwiinkqubo zokupholisa iinjini, ibronzi yeyona ikhethwayo.
4. Ubude bexesha elide kunye nokusebenza kakuhle kweendleko
Nangona iivalvu zobhedu zinokuba neendleko eziphezulu kwangaphambili, ixesha lazo elide lokuphila kunye neemfuno zolondolozo eziphantsi zenza ukuba zisebenzise imali eninzi ekuhambeni kwexesha. Ukutshintshwa okuncinci kunye nexesha eliphantsi lokungasebenzi kolondolozo kuncedisa ekongeni imali eninzi yokusebenza.
Iivalvu zebrass, nangona zingabizi kakhulu ekuqaleni, zisenokufuna ukutshintshwa rhoqo ngenxa yokugqwala, nto leyo ekhokelela kwiindleko eziphezulu ngokuhamba kwexesha.
