Ukuqonda Izixhobo zeValve yeHydrant

Yintoni iBronze?

I-bronze yi-alloy yesinyithi eyenziwe ngobhedu kunye ne-tin, kunye nezinye izinto ezifana ne-silicon, i-zinc, kunye ne-phosphorus eziphucula iimpawu zayo. Olu lwakhiwo lwenza i-bronze imelane kakhulu nokugqwala, ingakumbi kwiindawo ezichatshazelwe ngamanzi anetyuwa.I-Gunmetal, uhlobo lwe-tin bronze, iyasebenza kakhulu ekuthinteleni ukugqwala kwamanzi anetyuwa kunye nokususwa kwezinki, okwenza ukuba ilungele ukusetyenziswa elwandle njengeevalvu zombhobho. Ukongezwa kwetin kwandisa amandla kunye nobunzima be-alloy, okwenza ukuba ikwazi ukumelana nemithwalo enzima kunye neemeko ezinzima.

Yintoni iBrass?

I-Brass yenye i-alloy esekwe kwi-copper, kodwa ibandakanya i-zinc njengeyona nto iphambili yesibini. Ukwakheka kwayo okuqhelekileyo kuquka59-62% yobhedu, kunye ne-arsenic encinci, i-tin, i-lead, kunye ne-iron. Okuseleyo kuqulethwe yi-zinc. I-Brass isebenza kakuhle kwiindawo ezininzi, kodwa ukumelana kwayo nokugqwala kuxhomekeke kumxholo wayo we-zinc. Ii-alloys ezine-zinc engaphantsi kwe-15% ziyamelana nokungasuswa ngcono, ngelixa ezo zinamanqanaba aphezulu e-zinc zinokuba sesichengeni. I-DZR brass, equka i-arsenic, inika ukumelana okuphuculweyo nokungasuswa, okwenza ukuba ifaneleke ukusetyenziswa kwevalvu ye-hydrant kwiindawo ezingenamandla.

Ulwahluko oluPhambili phakathi kweBronze kunye neBrass

Ibronzi kunye nebronzi zahluke kakhulu ngokwakhiwa kunye nokusebenza. Ibronzi, kunye nomxholo wayo wetin, igqwesile ekumelaneni nokugqwala, ngakumbi kwiindawo ezinamanzi anetyuwa. Ikwanika amandla amakhulu kunye nokuqina xa ithwele imithwalo enzima. Kwelinye icala, ibronzi ixabisa kancinci kwaye kulula ukuyitshixa, kodwa ukumelana kwayo nokugqwala kuyahluka ngokusekelwe kumxholo we-zinc. Nangona ibronzi ikhethwa kwiivalvu ze-hydrant kwiimeko ezinzima, ibronzi inokukhethwa xa kusetyenziswe apho iindleko kunye nokusebenza kwayo zizinto eziphambili.

Ukumelana nokugqwala kwiivalvu zeHydrant

Indlela iBronze Eyenza Ngayo Ukumelana Nokugqwala

I-bronze ibonakalisa ukumelana nokugqwala okugqwesileyo, nto leyo eyenza ukuba ibe yinto ethembekileyo kwiivalvu ze-hydrant kwiindawo ezinzima. Umxholo wayo ophezulu we-copper, kunye ne-tin kunye nezinye izinto, kudala umqobo wendalo ngokuchasene ne-oxidation kunye neempendulo zeekhemikhali. Le propati ivumela i-bronze ukuba imelane nemiphumo yamanzi, kuquka amanzi anetyuwa, adla ngokukhawulezisa ukugqwala kwezinye izinto.

Kwiindawo zaselwandle okanye ezikunxweme,iivalvu zombhobho wobheduzigcina ulungelelwaniso lwesakhiwo sazo ngokuhamba kwexesha. Ukumelana kwe-alloy ne-dezincification, inkqubo apho i-zinc iphuma khona kwizinto, kuphucula ukuqina kwayo. Ukongeza, i-bronze imelana nokuchatshazelwa ziikhemikhali ezahlukeneyo, iqinisekisa ukusebenza rhoqo kwiinkqubo zokukhusela umlilo kwimizi-mveliso okanye koomasipala. Ukukwazi kwayo ukunyamezela iimeko ezinzima kuyenza ibe lukhetho olukhethwayo lokusetyenziswa ixesha elide.

Indlela iBrass Esebenza Ngayo Ekuchaseni Ukugqwala

I-Brass inika ukumelana nokugqwala okuphakathi, kuxhomekeke kwindlela equlunqwe ngayo. Ii-alloys ezinomxholo ophantsi we-zinc, ezifana ne-DZR (dezincification-resistant) brass, zisebenza ngcono kwiindawo apho kukho amanzi kunye nokufuma. Nangona kunjalo, i-brass isengozini enkulu yokugqwala xa ithelekiswa ne-bronze, ingakumbi kwiimeko ezirhabaxa ezifana nokuchatshazelwa ngamanzi anetyuwa.

Nangona kukho lo mda,iivalvu zombhobho wobheduZingasebenza kakuhle kwiindawo ezingabizi kakhulu. Umzekelo, zifanelekile ukusetyenziswa ngaphakathi okanye ezidolophini apho ukuvezwa kwezinto ezirhabaxa kuncinci. Ukongezwa kwe-arsenic okanye i-tin kwii-alloys ezithile zobhedu kuphucula ukumelana kwazo nokugqwala, nto leyo eyenza zibe lukhetho olufanelekileyo kwiimeko ezithile zokusetyenziswa.

Izinto Ezichaphazela Ukumelana Nokugqwala

Iimeko zendalo zidlala indima ebalulekileyo ekumiseleni ukumelana nokugqwala kwezinto zevalvu ye-hydrant. Izinto ezifana nokwakheka kwamanzi, ubushushu, kunye nokuvezwa kwiikhemikhali zichaphazela isantya sokugqwala. Iindawo zamanzi anetyuwa, umzekelo, zikhawulezisa inkqubo yokugqwala ngenxa yokubakho kwee-ion ze-chloride. Kwiimeko ezinjalo, ibronze idlula ibronze ngenxa yokuxhathisa kwayo kakhulu kumonakalo obangelwa yityuwa.

Iindawo zoshishino zinokubeka iivalvu ze-hydrant kwiikhemikhali okanye ungcoliseko olunokugqwalisa izinto ezithile. Amandla eBronze okumelana neempendulo zeekhemikhali enza ukuba ibe lukhetho olungcono kwezi ndawo. Kwelinye icala, ibrass inokwanela kwiindawo ezilawulwayo apho kungekho bungozi buncinci kwiiarhente zokugqwalisa. Ukuqonda iimeko ezithile zendalo kunceda ekukhetheni izinto ezifanelekileyo kwiivalvu ze-hydrant, ukuqinisekisa ukuqina nokuthembeka.
