Indawo yokuvala yama-valve ensimbi (I-DC341X-16 Ivalve uvemvane ene-flanged kabili) ngokuvamile ikhiqizwa ngu (I-valve ye-TWS)i-welding ebusweni. Izinto ezisetshenziselwa ukufakwa kwe-valve zihlukaniswe izigaba ezi-4 ezinkulu ngokohlobo lwe-alloy, okungukuthi ama-alloys asekelwe ku-cobalt, ama-alloys asekelwe ku-nickel, ama-alloys asekelwe ku-iron, nama-alloys asekelwe ethusi. Lezi zinto ze-alloy zenziwe zaba ama-electrode, izintambo zokushisela (kuhlanganise nezintambo ezine-flux-cored), ama-fluxes (okuhlanganisa i-transition alloy fluxes) kanye nama-alloy powders, njll., futhi abonakala ngokushisela i-arc manual, i-oxyacetylene ye-flame welding, i-tungsten argon arc welding, i-submer e-arcplasm e-automatic.
Ukukhethwa kwezisetshenziswa zokuvala i-valve ebusweni (DC341X3-10I-valve uvemvane ene-flanged kabiliindandatho yokuvala umzimba) ngokuvamile isekelwe kumazinga okushisa okusetshenziswa, ingcindezi yokusebenza kanye nokugqwala kwe-valve, noma uhlobo lwevalvu, ukwakheka kwendawo evalayo, ingcindezi ethile yokuvala kanye nengcindezi ethile evunyelwe, noma izimo zokukhiqiza nezokukhiqiza zebhizinisi, amandla okucubungula amathuluzi kanye nekhono lobuchwepheshe lendawo engaphezulu kanye nezidingo zabasebenzisi. Umklamo olungiselelwe kufanele futhi wamukelwe, futhi impahla engaphezulu yokuvala enenani eliphansi, inqubo elula yokukhiqiza nokusebenza kahle okuphezulu kokukhiqiza kufanele kukhethwe ngaphansi kwesimo sokwanelisa ukusebenza kwe-.I-D341X3-16 Ivalv uvemvane olugxilile oluphindwe kabilie) i-valve.
Ezinye zezinto ezisetshenziselwa ukuvelela ezindaweni zokuvala ama-valve zinefomu elilodwa kuphela, noma i-electrode noma intambo yokushisela noma i-alloy powder, ngakho-ke inye kuphela indlela yokubuka engasetshenziswa. Ezinye zenziwa zibe izinduku zokushisela, izintambo zokushisela noma izimpushana zengxubevange ngezindlela ezihlukahlukene, njenge-stellite l 6 ingxubevange, zombili izinduku zokushisela (D802), izintambo zokushisela (HS111) kanye nama-alloy powders (PT2102), bese kuba i-arc welding manual, i-oxy2acetylene flame welding, i-tungsten arcwire welding, i-tungsten i-arcwire i-plasma arc welding nezinye izindlela zingasetshenziswa ekushiseleleni phezulu. Lapho sikhetha izinto zokubeka phezulu endaweni yokuvala ama-valve, kufanele sicabangele ukukhethwa kwendlela yokubuka ngobuchwepheshe obuvuthiwe, inqubo elula kanye nokusebenza kahle okuphezulu kokukhiqiza kwebhizinisi, ukuze kuqinisekiswe ukufezeka kokusebenza kwayo ekukhiqizeni okungaphezulu kwendawo yokuvala.
Indawo yokuvala iyingxenye ebalulekile ye-valve (I-D371X-10 I-Wafer butterfly valve), futhi ikhwalithi yayo ithinta ngqo impilo yesevisi ye-valve. Ukukhethwa okunengqondo kwempahla yendawo yokuvala i-valve kungenye yezindlela ezibalulekile zokuthuthukisa impilo yesevisi ye-valve. Ukungaqondi kahle kufanele kugwenywe ekukhetheni izinto ezingaphezulu zokuvala ama-valve.
Inganekwane 1: Ukuqina kwevalvu (I-D371X3-16C) impahla engaphezulu yokuvala iphezulu, futhi ukumelana kwayo nokugqoka kuhle.
Ukuhlola kubonisa ukuthi ukumelana nokugqokwa kwezinto ezingaphezulu zokuvala ama-valve kunqunywa ukwakheka kwe-microstructure yensimbi. Ezinye izinto zensimbi ezine-austenite njenge-matrix kanye nenani elincane lesakhiwo sesigaba esinzima azinzima kakhulu, kodwa ukumelana kwazo kokugqoka kuhle kakhulu. Indawo yokuvala ye-valve inobunzima obuthile obuphakeme ukugwema ukulimala nokuklwejwa udoti oqinile phakathi nendawo. Zonke izinto ezicatshangelwayo, inani lobulukhuni HRC35~45 lifanelekile.
Inganekwane yesi-2: Intengo yezinto ezibonakalayo zokuvala ama-valve ziphezulu, futhi ukusebenza kwayo kuhle.
Intengo yezinto ezibonakalayo iyisici sayo sempahla, kuyilapho ukusebenza kwento ethile kuyisici sayo somzimba, futhi abukho ubuhlobo obudingekayo phakathi kwakho kokubili. Insimbi ye-cobalt kuma-alloys asekelwe ku-cobalt ivela kwamanye amazwe, futhi intengo iphezulu, ngakho intengo yezinto ezisekelwe ku-alloy ezisekelwe ku-cobalt iphezulu. Ama-alloys asekelwe ku-Cobalt abonakala ngokumelana okuhle kokugqoka emazingeni okushisa aphezulu, kuyilapho uma esetshenziswa ezimweni zokushisa ezivamile neziphakathi, intengo / ukusebenza kuphakeme kakhulu. Ekukhetheni izinto ezingaphezulu zokuvalwa kwe-valve, izinto ezinenani eliphansi/ukusebenza kufanele kukhethwe.
Inganekwane yesi-3: Uma impahla engaphezulu yokuvala yevalvu inokumelana nokugqwala okuhle endaweni eqinile edlayo, kufanele ivumelane nezinye imidiya egqwalayo.
Ukumelana nokugqwala kwezinto zensimbi kunomshini wayo oyinkimbinkimbi, into inokumelana nokugqwala okuhle endaweni eqinile egqwalayo, futhi izimo zishintsha kancane, njengezinga lokushisa noma ukugxila okuphakathi, ukumelana nokugqwala kuyashintshwa. Kwesinye isizinda sokugqwala, ukumelana nokugqwala kuyehluka kakhulu. Ukumelana nokugqwala kwezinto zensimbi kungaziwa kuphela ngokuhlolwa, futhi izimo ezifanele kufanele ziqondwe ukuze kusetshenziswe ireferensi ezintweni ezifanele, futhi akufanele zibolekwe ngokungaboni.
