UThintelo kunye noNyango lwe-Butterfly Valve Corrosion

Yintoni umhlwaiivalve butterfly?

Ukonakala kweevalvu zebhabhathane ngokuqhelekileyo kuqondwa njengomonakalo wesixhobo sesinyithi sevalvu phantsi kwesenzo sekhemikhali okanye imekobume ye-electrochemical. Ekubeni i-phenomenon "ye-corrosion" iyenzeka ekusebenzisaneni okuzenzekelayo phakathi kwesinyithi kunye nendalo engqongileyo, indlela yokuhlukanisa isinyithi kwindawo engqongileyo okanye ukusebenzisa izinto ezingezona zentsimbi zokwenziwa kugxininiso lokuthintela ukubola. Umzimba weivelufa butterfly(kubandakanywa nesivalo sevalve) ithatha uninzi lobunzima bevalve kwaye idibana rhoqo nendawo, ngoko ke ivalve yebhabhathane isoloko ikhethwa kumzimba.

Zimbini kuphela iindlela zokubola komzimba wevalveiivalve butterfly, oko kukuthi i-chemical corrosion kunye ne-electrochemical corrosion. Izinga lokubola kwayo limiselwa liqondo lobushushu, uxinzelelo, iipropathi zekhemikhali zeliphakathi, kunye nokunganyangeki kwe-corrosion ye-valve yomzimba. Izinga lokutya lingohlulwa libe ngamanqanaba amathandathu:

1. Ukumelana nokugqwesa okupheleleyo: izinga lokubola lingaphantsi kwe-0.001 mm / ngonyaka;

2. Ukuxhatshazwa ngokugqithisileyo kwe-corrosion: izinga lokubola 0.001-0.01 mm / ngonyaka;

3. Ukumelana nokubola: izinga lokubola 0.01-0.1 mm / ngonyaka;

4. Ukuxhatshazwa okuphezulu kwe-corrosion: izinga lokubola 0.1-1.0 mm / ngonyaka;

5. Ukunganyangeki kwe-corrosion: izinga lokubola 1.0-10 mm / ngonyaka;

6. Ukuchasana nokungabikho kwe-corrosion: izinga lokubola likhulu kune-10 mm / ngonyaka.

Indlela yokuthintela umhlwaiivalve butterfly?

I-anti-corrosion yomzimba wevalve yevalve yebhabhathane ikakhulu ngenxa yokhetho oluchanekileyo lwezixhobo. Nangona ulwazi malunga ne-anti-corrosion lucebile kakhulu, akulula ukukhetha okulungileyo, kuba ingxaki ye-corrosion inzima kakhulu, umzekelo, i-asidi ye-sulfuric iyingozi kakhulu kwintsimbi xa i-concentration iphantsi, kwaye xa i-concentration iphezulu, yenza ukuba insimbi ivelise ifilimu ye-passivation, enokuthintela ukubola; I-Hydrogen iboniswa kuphela i-corrosion kakhulu kwintsimbi kwiqondo lokushisa eliphezulu kunye noxinzelelo, kwaye ukusebenza kwe-corrosion yegesi ye-chlorine ayinkulu xa yomile, kodwa ukusebenza kwe-corrosion kunamandla kakhulu xa kukho ukufuma okuthile, kwaye izinto ezininzi azikwazi ukusetyenziswa. Ubunzima bokukhetha izixhobo zomzimba we-valve kukuba asikwazi ukuqwalasela iingxaki ze-corrosion kuphela, kodwa siphinde siqwalasele izinto ezifana noxinzelelo kunye nokumelana nokushisa, nokuba ngaba kunengqiqo ngokwezoqoqosho, nokuba kulula ukuyithenga. Ngoko kufuneka unikele ingqalelo.

1. Okwesibini kukuthatha amanyathelo e-lining, afana nelothe, i-aluminiyam, iiplastiki zobunjineli, irabha yendalo kunye nerabha yokwenziwa kwezinto ezahlukeneyo. Ukuba iimeko eziphakathi ziyakuvumela, le yindlela yokulondoloza.

2. Okwesithathu, xa uxinzelelo kunye neqondo lokushisa lingekho phezulu, izinto eziphambili zevalve yebhabhathane ene-fluorine zihlala zisebenza kakhulu ekukhuseleni ukubola.

3. Ukongezelela, umphezulu wangaphandle womzimba we-valve ubuye ugqweswe yi-atmosphere, kwaye i-ductile iron material ikhuselwe ngokubanzi nge-nickel plating.

I-TWS iza kuqalisa ngokukhawuleza umgca omtsha we-anti-corrosion, ogubungela uluhlu olupheleleyo lwezisombululo zevalvu ezifanaiivalve butterfly, iivalve zesango, khangela iivalvekunye neevalvu zebhola, njl. Olu luhlu lweemveliso lwamkela itekhnoloji yokumelana ne-corrosion ephezulu kunye neenkqubo ezikhethekileyo zonyango lwemathiriyeli ukugcina ukusebenza kokutywina okugqwesileyo kunye nokuzinza kokusebenza phantsi kweemeko zokusebenza ezigqithisileyo. Sizibophelele ekuboneleleni abathengi ngeemveliso ezihlala ixesha elide zevalvu yeshishini, ukwandisa kakhulu ubomi benkonzo yezixhobo, ukunciphisa iindleko zokugcinwa kubomi bonke.spanumjikelo, kunye nokunceda abathengi bafezekise izigqibo zokuthenga ixabiso eliphezulu.
