Yini okufanele ngiyenze uma ngihlangabezana nezinkinga zokungahlangani kanye nokungangeni kwe-valve ngemva kokushisela ama-valve?

1. Izici zesici
I-Unfused ibhekisela esimweni sokuthi insimbi yokushisela ayincibiliki ngokuphelele futhi ayihlanganiswanga nensimbi eyisisekelo noma phakathi kwezingqimba zensimbi yokushisela.
Ukwehluleka ukungena kubhekisela esimweni sokuthi impande yelunga elihlanganisiwe ayingene ngokuphelele.
Kokubili ukungahlanganisi kanye nokungangeni kuzonciphisa indawo ephumelelayo yokuwelda, kunciphise amandla nokuqina.
2. Izimbangela
Imbangela yokungahlangani: ugesi wokushisela mncane kakhulu noma isivinini sokushisela sishesha kakhulu, okuholela ekushiseni okunganele, futhi insimbi eyisisekelo kanye nensimbi yokugcwalisa akukwazi ukuncibilika ngokuphelele. I-angle ye-groove incane kakhulu, igebe lincane kakhulu noma unqenqema olubuthuntu lukhulu kakhulu, kangangokuthi i-arc ayikwazi ukungena ijule empandeni ye-groove ngesikhathi sokushisela, okuholela ekutheni insimbi eyisisekelo kanye nensimbi yokushisela kungahlangani. Kukhona ukungcola okufana nebala lamafutha kanye nokugqwala ebusweni be-weldment, okuthinta ukuncibilika nokuhlanganiswa kwensimbi. Ukusebenza okungalungile, njenge-angle ye-electrode engalungile, indlela engafanele yokuthutha ibha, njll., kwenza i-arc iphambuke emaphethelweni e-groove noma yehluleke ukumboza i-groove ngokwanele.
Izimbangela zokungangeni: Kufana nezinye izizathu zokungahlangani, njengomsinga wokushisela omncane kakhulu, isivinini sokushisela esisheshayo kakhulu, usayizi womsele ongafanele, njll. Lapho kushiselwa, i-arc inde kakhulu, futhi ukushisa kwe-arc kuyahlakazeka, okuholela ekuncibilikeni kabi kwensimbi yempande. Igebe lokuhlangana kwe-weldment alilingani, futhi kulula ukungabi nokungena kwe-weld engxenyeni enegebe elikhulu.
3. Ukucubungula
Ukwelashwa Okungaxubekile: Ezindaweni ezingaxubekile, isondo lokugaya lingasetshenziswa ukupholisha izingxenye ezingaxubekile bese liphinda lishibilike. Lapho kushibilikelwe kabusha, amapharamitha enqubo yokushibilika kufanele alungiswe ukuqinisekisa ukufakwa okwanele kokushisa ukuze kuncibilikiswe ngokuphelele insimbi eyisisekelo kanye nensimbi yokugcwalisa. Uma kungaxubeki ngaphakathi, ngokuvamile kuyadingeka ukusebenzisa izindlela zokuhlola ezingonakalisi ukunquma indawo kanye nobukhulu bokungaxubi, bese usebenzisa izindlela zokugaya i-carbon arc noma zokugaya ukususa izingxenye ezingaxubekile, bese wenza ukulungisa ukushibilika. Lapho ulungisa ukushibilika, naka ukuhlanza i-groove, lawula i-angle yokushibilika kanye nendlela yokuthutha ibha.
Ukwelashwa Okungangeni: Uma ukujula kokungena okungashiselwe kungajulile, ingxenye engakangeni ingasuswa ngokugaya ngesondo lokugaya, bese kulungiswa ukushisela. Ekujuleni okukhulu, ngokuvamile kuyadingeka ukusebenzisa i-carbon arc gouging noma i-machining ukususa zonke izingxenye zokungena kokushisela kuze kube yilapho insimbi enhle iveziwe, bese kulungiswa ukushisela. Lapho kulungiswa ukushisela, ugesi wokushisela, i-voltage kanye nesivinini sokushisela kufanele kulawulwe ngokuqinile ukuqinisekisa ukuthi impande ingangena ngokuphelele.
4. Lungisa izinto zokushisela
Ngokuvamile, izinto zokushisela ezifana noma ezifana nezinto eziyisisekelo zevalvu kufanele zikhethwe. Isibonelo, kumavalvu ensimbi ehlanganisiwe yekhabhoni, izinduku zokushisela ze-E4303 (J422) zingakhethwa; Kumavalvu ensimbi engagqwali, izinduku zokushisela zensimbi engagqwali ezihambisanayo zingakhethwa ngokuya ngezinto ezithile, njengezinduku zokushisela ze-A102 zensimbi engagqwali engu-304.amavalvu, Izinduku zokushisela ze-A022 zensimbi engagqwali engu-316Lamavalvu, njll.

I-Tianjin Tanggu Water-Seal Valve Co., Ltd ikhiqiza ikakhulukaziivalvu yebhabhathane, ivalvu yesango,Isihluzo se-Y, ivalvu yokulinganisa, ivalvu yokuhlola, njll.
