Ukonakala kweevalvu ngokuqhelekileyo kuqondwa njengomonakalo wemathiriyeli yentsimbi yevalvu phantsi kwentshukumo yeekhemikhali okanye imo engqongileyo ye-electrochemical. Ukusukela ukuba "umhlwa" isenzeko senzeka kunxibelelwano oluzenzekelayo phakathi kwesinyithi kunye nokusingqongileyo, indlela yokwahlula isinyithi kwindawo engqongileyo okanye ukusebenzisa izinto ezingeyiyo{1}}ezenziwe ngesinyithi kugxininiso lokuchasa{2}}ukuhlwa.
Umzimba wevalve (kubandakanywa nesivalo sevalvu) wevalve ithatha uninzi lobunzima bevalve kwaye idibana rhoqo nesiphakathi. Ngoko ke, i-valve ihlala ikhethwa kwizinto eziphathekayo ze-valve.
Umhlwa womzimba wevalvu awukho ngaphezu kweefom ezimbini, ezizezi, ukubola kweekhemikhali kunye nokubola kwe-electrochemical. Izinga lokubola kwayo limiselwa liqondo lobushushu, uxinzelelo, iipropathi zekhemikhali zeliphakathi, kunye nokunganyangeki kwe-corrosion ye-valufa yomzimba. Amazinga okubola angohlulwa abe ziindidi ezintandathu:
I-1, ukuxhathisa okupheleleyo kwe-corrosion: izinga lokubola lingaphantsi kwe-0.001 mm / ngonyaka;
2. Ukuchasana nokugqwesa okugqithisileyo: Izinga le-Corrosion 0.001 ukuya kwi-0.01 mm / ngonyaka;
I-3, ukuxhathisa kwe-corrosion: izinga lokubola kwe-0.01 ukuya kwi-0.1 mm / ngonyaka;
I-4, ukuxhathisa ukubola: izinga lokubola kwe-0.1 ukuya kwi-1.0 mm / ngonyaka;
I-5, ukunganyangeki kwe-corrosion: izinga lokubola kwe-1.0 ukuya kwi-10 mm / ngonyaka;
6, hayi umhlwa: izinga lokubola okukhulu kune-10 mm / ngonyaka.
I-anti-i-corrosion ye-valve yomzimba lukhetho oluchanekileyo lwemathiriyeli. Nangona idatha yokukhusela i-corrosion ityebile kakhulu, akukabi lula ukukhetha okulungileyo, kuba ingxaki ye-corrosion inzima kakhulu. Umzekelo, i-asidi ye-sulfuric iyingozi kakhulu kwintsimbi ekugxininiseni okuphantsi, kwaye ivelisa intsimbi kwiindawo eziphezulu. Ifilimu yePassivation inokuthintela ukubola; i-hydrogen ibonisa kuphela i-corrosion ephezulu kwintsimbi phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu; xa irhasi yeklorini ikwimeko eyomileyo, ukusebenza komhlwa akukho kukhulu, kodwa xa kukho ukufuma okuthile, ukusebenza komhlwa kunamandla kakhulu, kwaye izinto ezininzi azinakusetyenziswa{4}} Ubunzima ekukhetheni imathiriyeli yomzimba wevalve bukwinyani yokuba akunakwenzeka ukuqwalasela kuphela ingxaki yomhlwa, kodwa namandla okumelana noxinzelelo kunye nobushushu boqoqosho kwaye akukho lula, nokuba kuthengwe kwaye akukho ngqiqweni. Ngoko ke kufuneka ibe lukhuni{6}intliziyo.
Ilandelwa ngamanyathelo ombane, afana ne-lining lead, i-aluminiyam ye-lining, iiplastiki zobunjineli be-lining, i-rubber yendalo edibeneyo kunye nerabha yokwenziwa. Ukuba iimeko zosasazo ziyavuma, le yindlela yokulondoloza.
Kwakhona, phantsi kweemeko zoxinzelelo oluphantsi kunye nobushushu, usebenziso lwe{0}}lwezixhobo zomzimba zevalvu yentsimbi zingasebenza kakhulu ekuthinteleni ukubola.
Ukongeza, indawo yangaphandle yevalve iphantsi kwe-corrosion ye-atmospheric, kwaye izinto zetsimbi zikhuselwe ngokubanzi ngepeyinti yebrashi.
