Indzawo yekuvala emavalvu ensimbi (DC341X-16 Ivalvu yevivane lephindvwe kabili) ivame kwentiwa ngu ( .Ivalvi ye-TWS)kushisela lokusetulu. Tintfo letisetjentiselwa kufaka emavalvu emhlabatsini tehlukaniswe ngetigaba letingu 4 letinkhulu ngekuya kweluhlobo lwe alloy, lokungema alloys lasekelwe ku cobalt, ema alloys lasekelwe ku nickel, ema alloys lasekelwe ensimbini, kanye nema alloys lasekelwe ku copper. Letintfo te-alloy tentiwa tibe ngema-electrode, tintambo tekushisela (kufaka ekhatsi tintambo letine-flux-cored), ema-flux (kufaka ekhatsi ema-alloy flux ekugucuka) kanye netimpuphu te-alloy, njll., futsi tivela etulu ngekushisela ngesandla, kushisela nge-oxyacetylene ngelilangabi, kushisela kwe-tungsten argon nge-plasmc arc.
Kukhetfwa kwetintfo tekuvala ivalve lesetulu (DC341X3-10Ivalvu yevivane lephindvwe kabiliindandatho yekuvala umtimba) ivame kusekelwe ekushiseni kwekusetjentiswa, umfutfo wekusebenta kanye nekugcola kwevalve, noma luhlobo lwevalve, sakhiwo sendzawo yekuvala, umfutfo lotsite wekuvala kanye nekucindzeteleka lokutsite lokuvumelekile, noma kukhicita kanye netimo tekukhicita tebhizinisi, ikhono lekucubungula le-tech kanye ne-equi basebentisi. Umklamo lolungisiwe kufanele futsi wamukelwe, futsi tintfo tekuvala letisetulu letinentsengo lephansi, inchubo yekukhicita lelula kanye nekusebenta kahle kwekukhicita lokusezingeni leliphakeme kufanele kukhetfwe ngaphansi kwesimo sekwenetisa kusebenta kwe (D341X3-16 I-valv yevivane lephindvwe kabilie )ivalvu.
Letinye tintfo letisetjentiselwa kufaka etulu kwetindzawo tekuvala emavalve tinendlela yinye kuphela, noma i-electrode noma intfo yekushisela noma i-alloy powder, ngako-ke indlela yinye kuphela yekufaka etulu ingasetjentiswa. Labanye bentiwa babe tindvuku tekushisela, tintambo tekushisela noma imphuphu ye-alloy ngetindlela letehlukahlukene, njenge-stellite l 6 alloy, totimbili tindvuku tekushisela (D802), tintambo tekushisela (HS111) kanye netimpuphu te-alloy (PT2102), bese kushisela ngesandla nge-arc, kushisela nge-oxy2acetylene ar flame. kushisela kanye nempuphu plasma arc kushisela kanye naletinye tindlela kungasetjentiswa surfacing kushisela. Lapho kukhetsa tintfo surfacing for valve kuvala ebusweni, kufanele sicabangele kukhetsa surfacing indlela nge ubuchwepheshe evuthiwe, inqubo elula kanye ephezulu umkhiqizo kusebenta kahle ibhizinisi, kute kucinisekiswe kufezeka ukusebenza kwayo ekukhiqizeni surfacing ebusweni kuvala.
Indzawo yekuvala iyincenye lebalulekile yevalve (D371X-10 Ivalvu yeluvivane), futsi lizinga layo litsintsa ngco imphilo yenkonzo yevalve. Kukhetsa lokunengcondvo kwetintfo tendzawo yekuvala yevalve kungenye yetindlela letibalulekile tekutfutfukisa imphilo yenkonzo yevalve. Kungacondzani kufanele kugwenywe ekukhetseni valve kuvala tintfo ebusweni.
Insumansumane 1: Kucina kwevalve (D371X3-16C) impahla yekuvala ebusweni iphakeme, futsi kumela kwayo kwekugcoka kuhle.
Kuhlolwa kukhombisa kutsi kumelana nekugcoka kwemphahla lesetulu yekuvala ivalve kuncunywa yi-microstructure yemphahla yensimbi. Letinye tintfo tensimbi letine austenite njenge matrix kanye nesakhiwo lesincane sesigaba lesicinile akusito leticinile kakhulu, kepha kumela kwato kwekugcoka kuhle kakhulu. Lendzawo yekuvala ye valve inekucina lokutsite lokusetulu kwentela kugwema kulimala kanye nekuklwebheka ngetintfo leticinile letisemkhatsini. Konkhe lokucatshangelwako, inani lokucina HRC35 ~ 45 lifanelekile.
Insumansumane 2: Intsengo valve kuvala ebusweni impahla ephakeme, kanye kusebenta kwayo kuhle.
Intsengo yentfo sici sayo semphahla, kantsi kusebenta kwalentfo sici sayo semtimba, futsi kute budlelwane lobudzingekako emkhatsini walokubili. Lensimbi ye cobalt kuma alloys lasekelwe ku cobalt ivela kuletintfo letibuya kulamanye emave, futsi intsengo iphakeme, ngako intsengo yetintfo letisekelwe ku cobalt iphakeme. Ema alloys lasekelwe ku Cobalt abonakala ngekumelana kahle nekugcoka ngesikhatsi sekushisa lokusetulu, kantsi uma asetjentiswa etimeni tekushisa letijwayelekile naletisemkhatsini, intsengo/kusebenta kusetulu kakhulu. Ekukhetseni tintfo tekuvala ivalve lesetulu, tintfo letinentsengo lephansi/kusebenta kumele tikhetfwe.
Insumansumane 3: Uma ngabe intfo yekuvala lesetulu yevalve inekumelana lokuhle nekugcola endzaweni lecinile yekugcola, kumele ivumelane naletinye tindlela tekugcola.
Kumelana nekugcola kwetintfo tensimbi kunendlela yayo leyinkimbinkimbi, intfo inekumelana lokuhle nekugcola endzaweni lenemandla yekugcola, futsi timo tiyashintja kancane, njengekushisa noma kuhlanganiswa lokusemkhatsini, kumelana nekugcola kuyashintja. Kulenye indlela yekugcola, kumelana nekugcola kuyahluka kakhulu. Kumelana nekugcola kwetintfo tensimbi kungatiwa kuphela ngekuhlola, futsi timo letifanele kumele tivisiseke kwentela kubhekisa kusuka etintfweni letifanele, futsi akukafaneli tibolekelwe ngekungaboni.
