Kumenyekanisha ibikoresho bya valve byo kwangiza amazi yinyanja

Mu myaka yashize, hamwe n’imibereho y’abaturage n’iterambere ry’inganda, ikoreshwa ry’amazi meza ryiyongereye uko umwaka utashye.Mu rwego rwo gukemura ikibazo cy’amazi, imishinga minini minini y’inyanja irimo kubakwa cyane mu gihugu.Mugihe cyo kuvoma amazi yinyanja, hakwiye kwitabwaho cyane cyane kwangirika kwa chloride kubikoresho.Agaciroibibazo bifatika bikunze kugaragara kubintu bitemba.Kugeza ubu, ibikoresho by'ibanze by'ibikoresho bya valve byo kwangiza amazi yo mu nyanja ni nikel-aluminium umuringa, ibyuma bitagira umwanda, ibyuma bya duplex bitagira umuyonga hamwe n'icyuma cyangiza + icyuma.

Nickel Aluminium Bronze

Umuringa wa Nickel-aluminium ufite imbaraga zo kurwanya ihungabana ryangirika, kwangirika k'umunaniro, kwangirika kwa cavitation, kurwanya isuri hamwe n’ibinyabuzima byo mu nyanja byangiza.Ugereranije nicyuma kitagira umwanda mumazi yinyanja arimo 3% NaCI, nikel-aluminium bronze yumuringa ifite imbaraga zo kurwanya kwangirika.Kwangirika kwa nikel aluminium umuringa mumazi yinyanja ni ugusenyuka no kwangirika.Umuringa wa Nickel-aluminium wumva umuvuduko w’amazi yo mu nyanja, kandi iyo umuvuduko urenze umuvuduko ukabije, umuvuduko wa ruswa wiyongera cyane.

Ibyuma

Kurwanya kwangirika kwibyuma bitagira umwanda biratandukana nibigize imiti yibikoresho.304 ibyuma bidafite ingese birwanya kwangirika no guturika kwangirika mubidukikije byamazi arimo chloride, kandi ntibishobora gukoreshwa nkibintu bitembera mumazi yinyanja.316L nicyuma cya austenitike kitagira umuyonga kirimo molybdenum, gifite imbaraga zo kurwanya ruswa rusange, gutera ruswa no kwangirika.

Icyuma

Kugirango ugabanye ikiguzi cyumushinga, umubiri wa valve ufata ibyuma byuma byuma bya EPDM, naho disiki ya valve ifata ibyuma byangiza ibyuma birwanya ruswa.

(1) Icyuma cyangiza Halar

Halar ni cololymer isimburana ya Ethylene na chlorotrifluoroethylene, kimwe cya kabiri cya kirisiti na fluoropolymer.Ifite ruswa irwanya imiti myinshi kama kama nimbuto kama.

(2) Icyuma kibyara umurongo Nylon11

Nylon11 ni igishishwa cya thermoplastique kandi gishingiye ku bimera, gishobora kubuza gukura no gukura kw ibihumyo.Nyuma yimyaka 10 yikizamini cyo kwibiza mumazi yumunyu, icyuma kidafite ibimenyetso byerekana ruswa.Kugirango hamenyekane neza ko igifuniko gihamye kandi gifatanye neza, ubushyuhe bwo gukoresha Nylon11 ntibugomba kurenga 100 ℃ iyo bukoreshejwe mugutwikiriza ikinyugunyugu.Iyo uburyo bwo kuzenguruka burimo ibice byangiza cyangwa ibikorwa byo guhinduranya kenshi, ntibikwiye gukoresha igifuniko.Byongeye kandi, igifuniko kigomba kubuzwa gutoborwa no gukonjeshwa mugihe cyo gutwara no kwishyiriraho.
