Umphezulu wokutywina weevalvu zentsimbi (DC341X-16 Ivalve yebhabhathane eneflanged kabini) yenziwa ngokubanzi ngu (Ivalve ye-TWS) ukuwelda phezu komhlaba. Izinto ezisetyenziselwa i-valve surfacing zihlulwe zibe ziindidi ezi-4 eziphambili ngokohlobo lwe-alloy, ezizezi, iialloyi ezisekwe kwi-cobalt, i-nickel-based alloys, i-iron-based alloys, kunye ne-alloys esekwe kubhedu. Ezi zixhobo ze-alloy zenziwe kwi-electrode, iingcingo ze-welding (kubandakanya iingcingo eziguquguqukayo), i-fluxes (kuquka i-alloy fluxes) kunye ne-alloy powders, njl.
Ukukhethwa kwezixhobo zokuvala umphezulu wevalve (DC341X3-10Ivalve yebhabhathane eneflanged kabiniUmsesane wokutywina womzimba) ngokubanzi usekwe kubushushu bokusebenzisa, uxinzelelo lokusebenza kunye nokubola kwevalve, okanye uhlobo lwesivalo, ubume bomphezulu wokutywina, uxinzelelo olukhethekileyo lokutywina kunye noxinzelelo oluthile oluvumelekileyo, okanye imveliso kunye neemeko zokwenziwa kweshishini, amandla okusebenza kwesixhobo kunye nobuchule bobugcisa bokujonga umphezulu kunye neemfuno zabasebenzisi. Uyilo oluphuculweyo kufuneka lwamkelwe, kunye nesixhobo sokutywina somgangatho ngexabiso eliphantsi, inkqubo elula yokuvelisa kunye nokusebenza kakuhle kwemveliso kufuneka kukhethwe phantsi kwemeko yokwanelisa ukusebenza kwe.D341X3-16 Ivalv yebhabhathane eneflanged ephindwe kabinie) ivalve.
Ezinye zemathiriyeli ezisetyenziselwa ukuvelela komphezulu wevalve yokutywina zinefomu enye kuphela, okanye i-electrode okanye i-welding wire okanye i-alloy powder, ngoko ke inye kuphela indlela yokujonga phezulu enokusetyenziswa. Ezinye zenziwe zibe ziintonga ze-welding, iingcingo ze-welding okanye i-alloy powders ngeendlela ezahlukeneyo, ezifana ne-stellite l 6 i-alloy, zombini i-welding rods (D802), i-welding wires (HS111) kunye ne-alloy powders (PT2102), emva koko i-arc ye-arc ye-manual, i-oxy2acetylene ye-flame welding, i-tungsten i-arcwire ye-welding, i-tungsten i-arcwire, i-tungsten i-arcwire I-plasma arc welding kunye nezinye iindlela zingasetyenziselwa ukuwelda ngaphezulu. Xa sikhetha izixhobo zokujonga umphezulu wevalve yokutywina, kufuneka sithathele ingqalelo ukukhethwa kwendlela yokujonga phezulu ngetekhnoloji evuthiweyo, inkqubo elula kunye nokusebenza okuphezulu kwemveliso yeshishini, ukuze kuqinisekiswe ukufezekiswa kokusebenza kwayo kwimveliso engaphezulu yokutywina.
Umphezulu wokutywina yinxalenye ephambili yevalve (I-D371X-10 i-Wafer butterfly valve), kwaye umgangatho wayo uchaphazela ngqo ubomi benkonzo yevalve. Ukukhethwa okunengqiqo kwezinto eziphathekayo zokutywinwa kwendawo enye yeendlela ezibalulekileyo zokuphucula ubomi benkonzo yevalve. Ukungaqondi kakuhle kufuneka kugwenywe ekukhethweni kwezinto ezingaphezulu zokutywinwa kwevalve.
Intsomi 1: Ukuqina kwevalve (D371X3-16C) izinto zokutywina ezingaphezulu ziphezulu, kwaye ukumelana kwayo nokunxiba kulungile.
Iimvavanyo zibonisa ukuba ukuxhathisa kokunxiba kwezinto ezingaphezulu zokutywinwa kwevalve kumiselwa yi-microstructure yezinto zetsimbi. Ezinye izinto zetsimbi kunye ne-austenite njenge-matrix kunye nenani elincinci lesakhiwo sesigaba esinzima asikho nzima kakhulu, kodwa ukuxhathisa kwabo ukunxiba kuhle kakhulu. Umphezulu wokutywina wevalvu unobunzima obuthile obuphezulu ukunqanda ukwenzakala kunye nokukrwelwa bubutyobo obuqinileyo phakathi. Zonke izinto eziqwalaselwayo, ixabiso lobulukhuni HRC35 ~ 45 lifanelekile.
Intsomi yesi-2: Ixabiso lempahla yokutywina i-valve iphezulu, kwaye ukusebenza kwayo kuhle.
Ixabiso lezinto eziphathekayo luphawu lwalo lwempahla, ngelixa ukusebenza kwezinto eziphathekayo kuyimpawu zomzimba, kwaye akukho budlelwane obuyimfuneko phakathi kwezi zibini. Isinyithi se-cobalt kwi-cobalt-based alloys sivela kumazwe angaphandle, kwaye ixabiso liphezulu, ngoko ke ixabiso lezinto ezisekelwe kwi-cobalt ziphezulu. I-alloys esekelwe kwi-Cobalt ibonakaliswe ngokuxhatshazwa kakuhle kokugqoka kumaqondo aphezulu, ngelixa xa isetyenziswe kwiimeko eziqhelekileyo kunye neziphakathi kweqondo lokushisa, ixabiso / ukusebenza liphezulu. Ekukhethweni kwezixhobo zokutywina i-valve, izixhobo ezinexabiso eliphantsi / ukusebenza kufuneka zikhethwe.
Intsomi yesi-3: Ukuba indawo yokutywina yomphezulu wevalve inokumelana ne-corrosion elungileyo kwindawo eyomeleleyo esonakalisayo, kufuneka ihambelane nolunye uhlobo lweendaba ezonakalisayo.
Ukuxhatshazwa kwe-corrosion yezixhobo zetsimbi kunendlela yayo eyinkimbinkimbi, i-material inokumelana ne-corrosion efanelekileyo kwindawo eyomeleleyo e-corrosion medium, kunye neemeko zitshintsha kancinci, ezifana neqondo lokushisa okanye i-concentration ephakathi, ukuxhatshazwa kwe-corrosion kuguqulwa. Komnye umbindi wokutya, ukuxhathisa komhlwa kuyahluka kakhulu. Ukuxhatshazwa kwe-corrosion yezixhobo zetsimbi kunokwaziwa kuphela ngeemvavanyo, kwaye iimeko ezifanelekileyo kufuneka ziqondwe ngokubhekisele kwizinto ezifanelekileyo, kwaye akufanele zibolekwe ngokungaboniyo.
