Ukugqwala kwevalvu yensimbi engagqwali kubangela nezisombululo Ivalvu yensimbi engagqwali kanye nomehluko wevalvu yensimbi ye-carbon steel, Izizathu zokugqwala kwevalvu yensimbi engagqwali Cwaninga ukuthi ivalve yensimbi engagqwali ingagqwala yini, ungakwazi kuqala ukubeka ivalvu efanayo endaweni ehlukile ukuze uqinisekise ukuqhathanisa, uma sikhuluma nje, uma i-valve yensimbi engagqwali ibekwe endaweni eyomile, ngemuva kwesikhathi eside, i-valve ayiyona nje into entsha, kodwa futhi ayikho nokugqwala, kodwa uma i-valve ifakwe emanzini olwandle aqukethe usawoti omningi, hhayi abambalwa. izinsuku zizogqwala, Kungabonakala ukuthi ukumelana nokugqwala nokumelana nokugqwala kwama-valve ensimbi engagqwali nakho kudingeka kukhawulwe ngokusetshenziswa kwemvelo. Ngaphezu kwalokho, kusukela ezicini ze-valve yensimbi engagqwali ngokwayo, akukhona ukugqwala ngoba kukhona ungqimba lwefilimu ye-oxide ecebile nge-chromium ukuvimbela ama-athomu omoya-mpilo angaphandle nezinye izinhlayiya ezibangelwa ukuhlasela komonakalo entweni, ukuze inezici zokugqwala, kodwa lapho ifilimu yonakaliswa yizici zemvelo, njengoba ama-athomu e-oksijini engena e-ion yensimbi yamahhala, i-valve yensimbi engenasici izoveza ukugqwala. Kunezizathu eziningi zokubhujiswa kwefilimu ye-valve yensimbi engagqwali, okuholela ekugqwaleni, ifilimu ethile nezinye izinhlayiya zensimbi noma ukusabela kothuli lwe-electrochemical, ngesikhathi esifanayo nomoya omanzi njengendlela ephakathi, ukwakheka komjikelezo webhethri elincane, ukwenza insimbi engagqwali surface ukugqwala, kungase futhi kube insimbi engagqwali surface ifilimu ngqo ethintana acid, alkali kanye nezinye uketshezi ezonakalisayo, okubangelwa ukugqwala, njll Ngakho-ke, ukuze insimbi engagqwali valve nokugqwala, ekusetshenzisweni kwansuku zonke kufanele futhi banake ukuhlanza izinto, gcina i-valve ihlanzekile. Okubili, isisombululo se-valve yensimbi engagqwali Ngakho uqinisekisa kanjani ukuthi ubuso bensimbi buhlala bukhanya futhi abugqwali? I-Sanjing Valve Manufacturing Co., LTD. Iziphakamiso zezisebenzi ezingochwepheshe nezobuchwepheshe: 1. Kuyadingeka ukuhlanza nokukhuhla indawo yensimbi engagqwali yokuhlobisa njalo, susa okunamathiselwe futhi uqede izici zangaphandle ezibangela ukuguqulwa. 2. Indawo yolwandle kufanele isebenzise insimbi engagqwali engu-316, impahla engu-316 ingamelana nokugqwala kwamanzi olwandle. 3. Ukwakheka kwamakhemikhali kwamanye amashubhu ensimbi engagqwali emakethe akukwazi ukuhlangabezana nezindinganiso kazwelonke ezihambisanayo, kuze kufike ku-304 izidingo ezibonakalayo. Ngakho-ke, kuzophinde kubangele ukugqwala, okudinga ukuthi umsebenzisi akhethe ngokucophelela ukwakhiwa komkhiqizo wabakhiqizi abahloniphekile kanye namaphuzu okwakhiwa okunakwa ukuze avimbele ukwakhiwa kwemihuzuko nokungcola okunamathiselwe, ukwakhiwa kwensimbi engagqwali ngaphansi kwesimo sefilimu. Kodwa ngokunwetshwa kwesikhathi, uketshezi olusele lokunamathisela ngokuhambisana nempilo yesevisi yefilimu, ngemuva kokwakhiwa kwefilimu kufanele kususwe lapho ukugeza okungaphezulu, kanye nokusetshenziswa kwamathuluzi ensimbi engagqwali, kanye namathuluzi omphakathi okuhlanza insimbi ejwayelekile, ukuze ungavumeli ama-chips ensimbi anamathele kufanele ahlanzwe. Kufanele kuqashelwe ukuze kuvinjwe izidakamizwa zokuhlanza zikanokusho kazibuthe kanye namatshe ukuthi zingathintani nendawo yensimbi engagqwali, uma ukuthintana kufanele kugezwe ngokushesha. Ngemuva kokwakhiwa, umshini wokuhlanza ongathathi hlangothi namanzi kufanele usetshenziselwe ukugeza usimende, impushana nomlotha oxhunywe phezulu. I-valve yensimbi engagqwali kanye ne-carbon steel valve umehluko phakathi kwevalve yensimbi engenasici kanye nezakhi zezinto ezibonakalayo ze-carbon steel valve: Izinto ezijwayelekile zama-valve ensimbi engagqwali yi-CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), 321, I-1CR18NI9TI, 0CR18NI9, 310S, 2250 kanye ne-201 nezinye izinto ezijwayelekile zensimbi engagqwali ezingajwayelekile. I-CF8, CF3, CF8M, CF3M kanye nezinye izincwadi zokusakaza ikhodi, 304,316 kanye namanye amafomu edijithali amakwe njengefomu lekhodi yokuqamba. I-valve yensimbi engagqwali kanye nomehluko we-carbon steel valve Izakhi zezinto ezibonakalayo: Izinto ezijwayelekile zamavalvu ensimbi engagqwali yi-CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), 321, 1CR18NI9TI, 0CR18NI9, 310S, 2250 kanye 201 nezinye izinto ezijwayelekile zensimbi engagqwali ezingajwayelekile. I-CF8, CF3, CF8M, CF3M kanye nezinye izincwadi zokusakaza ikhodi, 304,316 kanye namanye amafomu edijithali amakwe njengefomu lekhodi yokuqamba. Futhi CF8 (304) jikelele American ikhodi ejwayelekile, futhi ikhodi yasekhaya ehambisana 0CR18NI9. Futhi okulingana kwasekhaya kwe-321 yi-1CR18NI9TI. I-304 ngokuvamile ine-C≤0.08, Mn≤2.00, P≤0.045, S≤0.030, Si≤1.00, CR18.0-20.0, Ni:8.0-11.0.316 izakhi zesakhiwo esibonakalayo yilezi: C: 0.08 ~ 0. 1.0, Mn: ≤2.0, Cr: 16.18.0, S: ≤0.03,P: ≤0.045, Mo≤2.0-3.0, ehambisana nezinga likazwelonke elithi 0Cr17Ni12Mo2. I-321 insimbi engagqwali inezici zamakhemikhali ezilandelayo: i-carbon C: ≤0.08; Si: ≤1.00, manganese Mn: ≤2.00, sulphur S: ≤0.030, P: ≤0.035, Cr: 17.00 ~ 19.00, Ni: 9.00 ~ 12.00, Ti: ≥5×C%. Futhi i-316L isuselwe ekuhlanganisweni kwe-nickel engu-316, inokumelana nokugqwala okuphezulu. Uhlobo oluhambisanayo lwe-310S luyi-2520 (0CR25NI20)). Sivame ukuyibiza ngensimbi enezigaba ezimbili, okuyinsimbi engagqwali enezinga eliphezulu lokushisa eliphezulu nokumelana nokugqwala, futhi intengo yayo ibiza kakhulu. Ukwakheka kwamakhemikhali: C :≤0.08, Si :≤1.00, Mn :≤2.00, P :≤0.035, S :≤0.030, Ni :≤19.00-22.00, Cr :≤24.00-26.0. I-valve yensimbi engagqwali kanye nokusetshenziswa kwensimbi engagqwali ***, evame ukusetshenziswa ezitshalweni zamakhemikhali, izimboni zokudla, izitshalo zamanzi, njll., inokumelana nokugqwala okuhle, ukumelana nengcindezi, ukumelana nokushisa okuphezulu, ukumelana nokugqoka, ukuhlanzeka nezinye izici, kubalulekile. amavalvu ezimbonini kanye civil kanye materials. Izinto ezijwayelekile ze-Carbon steel ziyi-carbon steel WCB cast steel, i-A105 insimbi eyakhiwe, insimbi engu-20 #, insimbi ye-LCB ephansi yokushisa nokunye. Ngokuvamile, i-WCB carbon steel ivame ukusetshenziswa. Ama-valve ensimbi e-WCB adlala indima enkulu ekuphileni kwansuku zonke noma amapayipi ezimboni, futhi umthamo uphezulu. I-A105 yenziwe ngensimbi ekhandiwe, enezakhiwo ezinhle eziqinile, ukuminyana okuphezulu, ukucindezela okukhulu nokumelana nokushisa okuphezulu, futhi ifanele amapayipi amancane. Insimbi engu-20# ngokuvamile isetshenziselwa izesekeli, ngokuvamile i-rod material, ngokuvamile i-bolts, amantongomane nokunye. I-LCB ukushisa okuphansi kwe-carbon steel, esetshenziswa ezimweni zokushisa eziphansi, njengamapayipi okugcina abandayo nokunye. Ukwakhiwa kwamakhemikhali we-WCB impahla: C≤ 0.3Mn ≤ 1.0Si ≤ 0.6P ≤ 0.05S ≤ 0.06Ni: 0.5Cr: 0.4Mo :0.25; I-A105 impahla yensimbi yokubumba kanye nezinto zokuphonsa zizoba nomehluko othize: C:≤ 0.35Si :≤ 0.35Mn: 0.6-1.05S :≤ 0.050P :≤0.040; I-LCB izinga lokushisa eliphansi le-carbon steel ≤0.30 ≤0.60 ≤1.0 insimbi LC3(-101℃)≤0.15 3.0 ~ 4.0. Ivalvu yensimbi engagqwali kanye nezici zevalvu yensimbi ye-carbon nezinkundla zokufaka isicelo: Amavalvu ensimbi engagqwali mahle ukuwasebenzisa kumapayipi agqwalayo namapayipi esitimu. Banokumelana nokugqwala, ukumelana nokushisa okuphezulu kanye nokumelana nokucindezela okuphezulu. Ngokuvamile asetshenziswa emapayipini agqwalayo ezitshalo zamakhemikhali, namapayipi amanzi kampompi noma izimboni zokudla. I-carbon steel valve ayinakho ukumelana nokugqwala, ingasetshenziselwa kuphela umusi, uwoyela, amanzi kanye namanye amapayipi aphakathi nendawo agqwalayo, futhi izindleko ze-carbon steel valve ziphansi kakhulu kunezindleko zensimbi engagqwali, ngakho ngokuvamile awekho umusi ogqwalayo namanye amapayipi. kusetshenziswa i-carbon steel, nama-valve ensimbi engagqwali egqwalayo nezinye izinto.
