Kusindikiza pamwamba pa mavavu achitsulo (DC341X-16 valavu yagulugufe yopindika pawiri) kawirikawiri amapangidwa ndi (TWS valve) kuwotcherera pamwamba. Zida zomwe zimagwiritsidwa ntchito poyang'ana ma valve zimagawidwa m'magulu akuluakulu a 4 malinga ndi mtundu wa alloy, omwe ndi cobalt-based alloys, nickel-based alloys, iron-based alloys, ndi copper-based alloys. Zida za aloyi zimapangidwa kukhala maelekitirodi, mawaya owotcherera (kuphatikiza mawaya a flux-cored), fluxes (kuphatikiza kusintha kwa alloy fluxes) ndi ma aloyi ufa, ndi zina zambiri, ndipo amawonekera ndi kuwotcherera pamanja, kuwotcherera kwamoto wa oxyacetylene, kuwotcherera kwa tungsten argon arc, ma welding a arc plasma, submer ndi arcaplasm.
Kusankhidwa kwa ma valve osindikizira pamwamba pa zipangizo (DC341X3-10Vavu yagulugufe yamitundu iwiri yowoneka bwinomphete yosindikizira) nthawi zambiri imachokera ku kutentha kwa ntchito, kuthamanga kwa ntchito ndi kuwonongeka kwa valavu, kapena mtundu wa valavu, mawonekedwe a malo osindikizira, kusindikiza kwapadera ndi kukakamizidwa kwapadera, kapena kupanga ndi kupanga zinthu zamalonda, mphamvu yogwiritsira ntchito zipangizo ndi luso lapamwamba lapamwamba ndi zofunikira za ogwiritsa ntchito. Kukonzekera kokwanira kuyeneranso kutsatiridwa, ndipo zosindikizira pamwamba pamtengo wotsika, njira zosavuta zopangira komanso kupanga bwino ziyenera kusankhidwa pansi pa chikhalidwe chokwaniritsa ntchito ya .D341X3-16 valavu yagulugufe yopindika pawirie) valavu.
Zina mwazinthu zomwe zimagwiritsidwa ntchito poyang'ana pamalo osindikizira ma valve zimakhala ndi mawonekedwe amodzi okha, kapena ma elekitirodi kapena waya wowotcherera kapena ufa wa aloyi, kotero njira imodzi yokha yowonekera ingagwiritsidwe ntchito. Ena amapangidwa kukhala ndodo kuwotcherera, mawaya kuwotcherera kapena aloyi ufa m'njira zosiyanasiyana, monga stellite L 6 aloyi, ndodo zonse kuwotcherera (D802), kuwotcherera mawaya (HS111) ndi aloyi ufa (PT2102), ndiye kuwotcherera pamanja arc, oxy2acetylene flame kuwotcherera, tungsten arcwire ufa, tungsten arcwire ufa kuwotcherera kwa plasma arc ndi njira zina zitha kugwiritsidwa ntchito pakuwotcherera. Posankha zipangizo zopangira pamwamba pazitsulo zosindikizira ma valve, tiyenera kuganizira za kusankha njira yowonekera ndi teknoloji yokhwima, njira yosavuta komanso yogwira ntchito kwambiri yamakampani, kuti atsimikizire kuti ntchito yake ikuchitika pakupanga pamwamba pa kusindikiza pamwamba.
Kusindikiza pamwamba ndiye gawo lofunikira la valve (D371X-10 Wafer butterfly valve), ndipo khalidwe lake limakhudza mwachindunji moyo wautumiki wa valve. Kusankhidwa koyenera kwa zinthu zapamadzi osindikizira ma valve ndi imodzi mwa njira zofunika zowonjezera moyo wautumiki wa valve. Kusamvetsetsana kuyenera kupewedwa posankha zipangizo zosindikizira ma valve pamwamba.
Bodza 1: Kulimba kwa valve (D371X3-16C) kusindikiza pamwamba ndipamwamba, ndipo kukana kwake kumakhala bwino.
Zoyesera zikuwonetsa kuti kukana kwazitsulo zotsekera ma valve pamwamba kumatsimikiziridwa ndi microstructure yazitsulo zachitsulo. Zida zina zachitsulo zokhala ndi austenite monga matrix ndi kamangidwe kakang'ono ka gawo lolimba sizili zovuta kwambiri, koma kukana kwawo kuvala ndikwabwino kwambiri. Malo osindikizira a valve ali ndi kulimba kwina kwakukulu kuti asavulazidwe ndi kukanda ndi zinyalala zolimba pakati. Zinthu zonse zomwe zimaganiziridwa, kuuma kwa mtengo wa HRC35 ~ 45 ndikoyenera.
Bodza lachiwiri: Mtengo wa zida zosindikizira ma valve ndi apamwamba, ndipo magwiridwe ake ndi abwino.
Mtengo wa chinthu ndi chikhalidwe chake chamtengo wapatali, pamene machitidwe a zinthuzo ndi mawonekedwe ake, ndipo palibe mgwirizano wofunikira pakati pa ziwirizi. Chitsulo cha cobalt mu alloys opangidwa ndi cobalt chimachokera kunja, ndipo mtengo wake ndi wokwera, choncho mtengo wa cobalt-based alloy zipangizo ndi wapamwamba. Ma alloys opangidwa ndi Cobalt amadziwika ndi kukana kwabwino kwa kuvala pa kutentha kwakukulu, pomwe amagwiritsidwa ntchito munyengo yanthawi zonse komanso yapakati kutentha, mtengo / magwiridwe antchito ndi okwera kwambiri. Posankha zipangizo zosindikizira za valve, zipangizo zotsika mtengo / zogwira ntchito ziyenera kusankhidwa.
Bodza lachitatu: Ngati chosindikizira pamwamba pa valavu chili ndi kukana kwa dzimbiri pamalo amphamvu owononga, chimayenera kusinthira kuzinthu zina zowononga.
Kukana kwa dzimbiri kwa zida zachitsulo kumakhala ndi makina ake ovuta, chinthucho chimakhala ndi kukana kwabwino kwa dzimbiri mu sing'anga yamphamvu yowononga, ndipo zinthu zimasintha pang'ono, monga kutentha kapena ndende yapakati, kukana kwa dzimbiri kumasinthidwa. Kwa sing'anga ina yowononga, kukana kwa dzimbiri kumasiyanasiyana kwambiri. Kukana kwa dzimbiri kwa zida zachitsulo kumatha kudziwika kudzera muzoyeserera, ndipo zofunikira ziyenera kumveka kuti zifotokozedwe kuchokera kuzinthu zofunikira, ndipo siziyenera kubwerekedwa mwachimbulimbuli.
