Indawo ebeka uphawu lama-valves ensimbi (DC341X-16 Double Flanged Butterfly Valve) kuvame ukwenziwa (I-TWS Valve) I-surfacing welding. Izinto ezisetshenziselwa i-valve surfacing zihlukaniswe izigaba ezi-4 ezinkulu ngokuya ngohlobo lwe-alloy, okungukuthi ama-alloys asuselwa ku-cobalt, ama-alloys asuselwa ku-nickel, ama-alloys asuselwa kwithusi. Lezi zinto zokwenziwa ze-alloy zenziwa zaba ngama-elektrodi, izintambo ze-welding (kufaka phakathi izintambo ze-flux), i-fluxes (kufaka phakathi i-arloy polding, tungsten argon arc welding, i-arch argon arc welding, i-plasma athoma welding.
Ukukhethwa kwezinto ezivuthayo ze-valveDC341X3-10I-valve ye-eccentric butterfly ephindwe kabiliIndandatho yokubopha umzimba) ngokuvamile isuselwa ekushiseni ukusetshenziswa, ukunakekelwa kwengcindezelo ye-valve, noma uhlobo lwe-valve, ukucindezela okuqondile, noma ukukhiqizwa kwengcindezi yebhizinisi, amandla obuchwepheshe we-surfacing kanye nezidingo zabasebenzisi. Idizayini eyenziwe kahle kufanele futhi yamukelwe, futhi impahla ebekelwe uphawu elingaphezulu ngentengo ephansi, inqubo elula yokukhiqiza kanye nokusebenza kahle kokukhiqiza okuphezulu kufanele kukhethwe ukusebenza kahle kokwenelisa ukusebenza kwe (D341X3-16 I-Double Flanged Butterfly Valvly Valve) i-valve.
Ezinye zezinto zokwakha ezisetshenziselwa i-surfcing of valve seaning surfaces zinefomu elilodwa kuphela, noma i-electrode noma i-wire ye-welding noma i-alloy powder, ngakho-ke kuphela indlela ye-surfacing eyodwa engasetshenziswa. Ezinye zenziwa izinduku ze-welding, izintambo ze-welding noma i-aloy powders ngezindlela ezahlukahlukene, njenge-stellite l 6 alloy (DT202), i-ark210), i-args210), i-argon argon arc welding, wire argon arc welding, wire feed plasma arc I-Welding ne-Powder Plasma ye-ARC Welding nezinye izindlela zingasetjenziswa nge-surfacing welding. Lapho ukhetha izinto ezisetshenziswayo ze-surfacing for the valve seaning ebusweni, kufanele sicabangele ukukhethwa kwendlela ye-surfacing nobuchwepheshe obuvuthiwe, inqubo elula nokusebenza kahle kokukhiqizwa kwebhizinisi, ukuze kuqinisekiswe ukugcwaliseka kokusebenza kwayo kwe-surfacing of the ukuvalwa kwe-surfacing kwendawo yokubekwa uphawu.
Indawo yokubopha uphawu yingxenye ebalulekile ye-valve (D371X-10 wafer butterfly valve), futhi imfanelo yawo ithinta ngqo impilo yenkonzo ye-valve. Ukukhetha okunengqondo kokuqukethwe kwe-valve seaning komhlaba kungenye yezindlela ezibalulekile zokwenza ngcono impilo yensiza ye-valve. Ukungaqondi kahle kufanele kugwenywe ekukhetheni izinto zobuso be-valve zibopha.
Inganekwane 1: Ubulukhuni be-valve (D371X3-16C) Ukuvalwa kokuvalwa kokuvalwa kwendawo kuphezulu, futhi ukumelana kwaso gqoka kuhle.
Izivivinyo zibonisa ukuthi ukumelana nokugqokwa kwe-valve ukubeka uphawu komhlaba kunqunywa yi-misfructure yezinto zensimbi. Ezinye izinto zensimbi ne-aucen njenge-matrix kanye nenani elincane lesigaba esinzima abunzima kakhulu, kodwa ukumelana kwazo kokugqoka muhle kakhulu. Indawo ebekelwe uphawu le-valve inobulukhuni obuthile obuthile bokugwema ukulimala futhi bakhungathekiswa udoti olunzima oluphakathi nendawo. Zonke izinto ezibhekwayo, Inani le-Hardnessness Value HRC35 ~ 45 lifanelekile.
Inkolelo-ze 2: Intengo ye-valve ebopha indawo yangaphandle iphezulu, futhi ukusebenza kwawo kuhle.
Intengo yezinto ezibonakalayo iyisici sayo sezimpahla, kuyilapho ukusebenza kwezinto ezibonakalayo kuyisici sayo somzimba, futhi abukho ubudlelwano obudingekayo phakathi kwalokhu okubili. I-Cobalt Metal kuma-alloys asuselwa ku-cobalt avela ekungenisweni, futhi intengo ephezulu, ngakho-ke intengo yezinto zokwakha ezenzelwe i-cobalt iphezulu. Ama-alloys asuselwa ku-cobalt abonakala ngokumelana kahle kokugqoka emazingeni okushisa aphezulu, kuyilapho asetshenziswa ezimweni zokushisa ezijwayelekile neziphakathi, intengo / ukusebenza kuphezulu. Ekukhetheni izinto ze-valve zibopha uphawu, izinto ezinamanani aphansi / ukusebenza kufanele kukhethwe.
Inkolelo-ze 3: Uma ingaphezulu lokubopha uphawu le-valve linokuphikiswa okuhle kokugqwala endaweni eqinile eqinile, kufanele ivumelane neminye imidiya ewonakalisayo.
Ukumelana nokugqwala kwezinto zensimbi kunesimo sayo esiyinkimbinkimbi, impahla inokumelana kahle nokugqwala okunamandla okuqinile, futhi izimo zishintsha kancane, njengokuhlushwa okuphakathi nendawo, ukumelana nokugqwala kuyashintshwa. Kokunye okuphakathi kwe-Complosive, ukumelana nokugqwala kuyahlukahluka. Ukumelana nokugqwala kwezinto zensimbi kungaziwa kuphela ngocwaningo, futhi izimo ezifanele kumele ziqondwe ukuze zibhekwe ezintweni ezifanele, futhi akufanele zibolekwe ngokungaboni.
