Yini okufanele ngiyenze uma ngihlangabezana nokukhubazeka okungahlanganisi nokungangeni ngemva kokushiselwa kwe-valve?

1. Izici zokukhubazeka
Ukungafakwanga kubhekisela kwinto yokuthi insimbi yokushisela ayincibiliki ngokuphelele futhi ihlanganiswe nesisekelo sensimbi noma phakathi kwezingqimba zensimbi yokushisela.
Ukwehluleka ukungena kubhekisela kwinto yokuthi impande yejoyinti elishiselwe ayingeni ngokuphelele.
Kokubili ukungahlanganisi nokungangeni kuzonciphisa indawo esebenzayo ye-weld ye-weld, kunciphise amandla nokuqina.
2. Izimbangela
Isizathu sokungahlanganisi: i-welding current incane kakhulu noma isivinini se-welding sishesha kakhulu, okuholela ekushiseni okwanele, futhi isisekelo sensimbi ne-filler metal ayikwazi ukuncibilika ngokugcwele. I-groove angle incane kakhulu, igebe lincane kakhulu noma unqenqema olubuthuntu likhulu kakhulu, ukuze i-arc ingakwazi ukungena ijule empandeni ye-groove ngesikhathi sokushisela, okuholela ekutheni isisekelo sensimbi nensimbi yokushisela ingahlangani. Kukhona ukungcola okufana nebala likawoyela nokugqwala ebusweni be-weldment, okuthinta ukuncibilika nokuhlanganiswa kwensimbi. Ukusebenza okungalungile, okufana ne-engeli ye-electrode engalungile, indlela engafanele yokuthutha ibha, njll., kwenza i-arc ichezuke onqenqemeni lwe-groove noma yehluleke ukumboza ngokwanele umsele.
Izimbangela zokungangeni: Kufana nezinye izizathu zokungahlanganisi, njenge-welding current encane kakhulu, isivinini sokushisela esisheshayo, usayizi we-groove ongafanele, njll. Uma i-welding, i-arc yinde kakhulu, futhi ukushisa kwe-arc kuyahlakazeka, okuholela ekuncibilikeni okungekuhle kwezimpande zensimbi. Igebe lomhlangano we-weldment alilingani, futhi kulula ukungabi nokungena kwe-weld engxenyeni enegebe elikhulu.
3. Iyacubungula
Ukwelashwa okungahlanganisiwe: Ezindaweni ezingahlanganisiwe, isondo lokugaya lingasetshenziswa ukupholisha izingxenye ezingahlanganisiwe bese lishiselwa kabusha. Lapho u-welding kabusha, imingcele yenqubo yokushisela kufanele ilungiswe ukuze kuqinisekiswe ukushisa okwanele ukuze kuncibilike ngokugcwele isisekelo sensimbi nensimbi yokugcwalisa. Ngokungahlanganisi kwangaphakathi, ngokuvamile kuyadingeka ukuthi kusetshenziswe izindlela zokuhlola ezingabhubhisi ukuze kutholwe indawo kanye nezinga lokungaxubanisi, bese usebenzisa i-carbon arc gouging noma izindlela zomshini ukususa izingxenye ezingahlanganisi, bese ulungisa. ukushisela. Lapho ulungisa i-welding, qaphela ukuhlanza i-groove, lawula i-angle ye-welding kanye nendlela yokuthutha ibha.
Ukwelashwa okungenakunyakaziswa: Uma ukujula kokungena okungahlanganisiwe kungajulile, ingxenye engangenisiwe ingasuswa ngokugaya ngesondo lokugaya, bese ilungisa i-welding. Ekujuleni okukhulu, ngokuvamile kuyadingeka ukusebenzisa i-carbon arc gouging noma machining ukususa zonke izingxenye zokungena kwe-weld kuze kuvele insimbi enhle, bese ulungisa ukushisela. Lapho kulungiswa i-welding, i-welding current, isivinini se-voltage kanye ne-welding kufanele ilawulwe ngokuqinile ukuze kuqinisekiswe ukuthi impande ingangena ngokugcwele.
4. Lungisa izinto zokushisela
Ngokuvamile, izinto zokushisela ezifanayo noma ezifana nesisekelo se-valve kufanele zikhethwe. Isibonelo, kuma-valve we-carbon steel ajwayelekile, i-E4303 (J422) izinduku zokushisela zingakhethwa; Kuma-valve ensimbi engagqwali, izinduku zokushisela zensimbi engagqwali ezihambisanayo zingakhethwa ngokuya ngezinto ezithile, njengezinduku zokushisela ze-A102 zensimbi engagqwali engama-304.ama-valve, izinduku zokushisela ze-A022 zensimbi engagqwali engu-316Lama-valve, njll.

I-Tianjin Tanggu Water-Seal Valve Co., Ltd ikhiqiza ikakhulukaziuvemvane valve, i-valve yesango,I-Y-strainer, i-valve yokulinganisa, i-valve yokuhlola, njll.
