"Uphando malunga nokuNchasa ukuRhwalala: Ukusetyenziswa kweValufa yeGlobe yeFlange yaseTshayina kwiShishini leMichiza"
1,Intshayelelo
Izivalo zeglowubhu zeflange zaseTshayina zidlala indima ebalulekileyo kwishishini lemichiza, kwaye ukuxhathisa kwabo kokubola kuchaphazela ngqo uzinzo kunye nokhuseleko lwenkqubo yokuvelisa. Eli nqaku lijonge ukuphonononga ukusebenza kokumelana nomhlwa kweevalvu zeglowubhu zeflange ezisemgangathweni waseTshayina kunye nokusetyenziswa kwazo kushishino lwemichiza, ukubonelela ngereferensi yokusebenza yobunjineli kwiinkalo ezinxulumeneyo.
2,Ukusebenza kokumelana nokonakala kweevalvu zeglowubhu ezisemgangathweni zaseTshayina
Ukumelana nomhlwa kweevalvu zeglowubhu yeflange esemgangathweni yaseTshayina ikakhulu kuxhomekeke kwizinto zazo kunye nenkqubo yokuvelisa. Izinto eziqhelekileyo ezinganyangekiyo kwi-corrosion ziquka insimbi engagqwali, i-duplex steel, njl., Enokugcina uzinzo oluhle kwimidiya ephazamisayo njenge-asidi kunye ne-alkali. Ukongeza, ngokulungiselela inkqubo yokuvelisa kunye nonyango lwangaphezulu, ukuxhathisa kwe-corrosion yevalve kunokuphuculwa ngakumbi.
Kwishishini lemichiza, iivalvu zeglowubhu zeflange eziqhelekileyo zaseTshayina zisetyenziswa ngokubanzi kwiinkqubo zemibhobho yemithombo yeendaba eyonakalisayo. Ukusebenza kokutywinwa kwayo okuzinzileyo kunye nobomi benkonzo ende buyenza ibe lolona khetho lufanelekileyo lokuphatha ulwelo oludlekayo. Kwangaxeshanye, iivalvu zeglowubhu zeflange zaseTshayina zineengenelo zesakhiwo esilula, ukwenziwa lula kunye nokugcinwa, ezinokuhlangabezana neemfuno zokusebenza kunye nokhuseleko lweshishini lemichiza yeevalvu.
3,Iimeko zokusetyenziswa kweevalvu zeglowubhu zeflange zaseTshayina kushishino lwemichiza
Ukuthatha ivalve yeglowubhu yeglowubhu yoxinzelelo olukwinqanaba elimbini, isetyenziswa kakhulu kwishishini lemichiza. Izinto zentsimbi zesigaba esiphindwe kabini zinokuxhathisa okulungileyo kwi-chloride ion stress corrosion kunye ne-sulfide stress corrosion, kunye namandla aphezulu omatshini, okwenza ukuba isetyenziswe ngokubanzi kumashishini afana nepetroleum, igesi yendalo kunye neshishini lemichiza. Kwiimeko zokubola kweekhemikhali, iivalve zeglobhu zeglobhu ezinoxinzelelo lwentsimbi ezimbini ezinoxinzelelo oluphezulu zinokusikwa ngokuthembekileyo okanye zidibanise imidiya yombhobho, ziqinisekise ukusebenza okuzinzile kwenkqubo yokuvelisa.
Ukongeza, iivalvu zeglowubhu zeflange eziqhelekileyo zaseTshayina zisetyenziswa ngokubanzi kwiinkqubo zemibhobho yomphunga kwishishini. Kwimibhobho yomphunga kwishishini kwindawo yefektri, ngenxa yeempawu zobude bombhobho omde, iiparamitha eziphakamileyo, ukwandiswa kwe-thermal enkulu, kunye nemekobume entsonkothileyo, iimfuno eziphezulu zibekwe phambili ekusebenzeni kokumelana nokubola kweevalvu. Ukusebenza okugqwesileyo kwevalve yeglowubhu yeflange yaseTshayina yenza ukuba ibe lolona khetho lufanelekileyo kwezi meko zinzima zokusebenza.
4,Amaqhinga okuphucula ukuxhathisa umhlwa kweevalvu zeglowubhu zeflange eziqhelekileyo zaseTshayina
Ukuphucula ukuxhathisa umhlwa kweevalvu zeglowubhu yeflange esemgangathweni yaseTshayina, ezi zicwangciso zilandelayo zinokumkelwa:
Khetha izixhobo ezinokumelana ne-corrosion egqwesileyo, njengentsimbi ephindwe kabini, intsimbi engatyiwa, njl.
Lungiselela iinkqubo zokuvelisa kunye nobuchule bonyango lomphezulu, njengokusebenzisa unyango lwe-nitriding, ukutshiza i-anti-corrosion coatings, njl., Ukuphucula ukuxhathisa umphezulu we-valve.
Gcina kwaye uhlole iivalvu rhoqo, uchonge ngokukhawuleza kwaye ulungise imiba enokuthi ibekho, uqinisekise ukusebenza okuqhelekileyo kweevalvu kunye nokwandisa ubomi bazo benkonzo.
5,Ukuqukumbela
Ivalve yeglowubhu yeflange esemgangathweni yaseTshayina inoluhlu olubanzi lwamathemba osetyenziso kushishino lweekhemikhali. Ngokukhetha izinto ezinganyangekiyo kwi-corrosion, ukuphucula iinkqubo zokuvelisa, kunye nokuqhuba ukugcinwa rhoqo kunye nokuhlolwa, ukusebenza kwe-corrosion resistance of valves kunokuphuculwa ngakumbi, ukuqinisekisa ukusebenza kwabo okukhuselekileyo kunye nokuzinza kwishishini lemichiza. Kwixesha elizayo, kunye nenkqubela phambili eqhubekayo yenzululwazi yemathiriyeli kunye nobugcisa bokuvelisa, ukusebenza kokumelana nokubola kwezivalo zeglowubhu ezisemgangathweni zaseTshayina ziya kuphuculwa ngakumbi, zibonelele ngeziqinisekiso ezithembeke ngakumbi kuphuhliso lweshishini lemichiza.
Nceda uqaphele ukuba umxholo ochazwe kweli nqaku usekelwe kulwazi olukhoyo kunye namava, kwaye kwizicelo eziphathekayo, uhlalutyo oluthile kunye nokukhethwa kufuneka kuqhutywe ngokusekelwe kwiimeko ezithile zokusebenza kunye neemodeli zevalve. Okwangoku, xa ukhetha, ufaka, kwaye ugcina iivalve, imigangatho efanelekileyo kunye neenkcukacha kufuneka zilandelwe ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo.
