Kusiyana Pakati pa Valavu Yachitsulo Yopangidwa ndi Valavu Yachitsulo Yotayidwa

I. Njira Yopangira

Valavu Yoyang'anira Chitsulo Yopangidwa ndi Forged Steel Yopangidwa ku China:

Chopangidwa kudzera mu njira yopangira, billet yachitsulo imatenthedwa ndipo mphamvu (monga kuponda, kutulutsa) imagwiritsidwa ntchito kuti ipangidwe, kenako kukonza kwamakina kumachitika.

Njira yopangira imapangitsa kuti chitsulocho chikhale choyeretsedwa komanso kapangidwe kake kakhale kokhuthala, kopanda zolakwika monga ma pores ndi zotsalira za slag.

Valavu Yopangidwa ndi Chitsulo:

Chitsulo chosungunuka chimapangidwa kudzera mu njira yopangira zinthu, chomwe chimathiridwa mu nkhungu kuti chizizire ndikupanga, kenako chimakonzedwa.

Njira yopangira zinthu ingayambitse mavuto monga ma pores, ma shrinkage caries kapena kapangidwe kosagwirizana, zomwe ziyenera kukonzedwanso kudzera mu kukonza pambuyo pake.

II. Katundu wa Zinthu

Valavu Yachitsulo Yopangidwa:

Mphamvu yayikulu: Kupangira kumachotsa zolakwika zamkati, ndipo mphamvu ya makina (kukana kugwedezeka ndi kukana kugunda) ndi yabwino kuposa ya castings.

Kukana bwino kupanikizika: koyenera kupanikizika kwambiri, kutentha kwambiri kapena ntchito yoopsa kwambiri.

Kutseka bwino: Chitsulocho chili ndi kuchuluka kwakukulu ndipo sichimatuluka mosavuta.

Valavu Yopangidwa ndi Chitsulo:

Kulimba kotsika: Kapangidwe kake kakhoza kukhala ndi zolakwika zazing'ono kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kuthyoka ming'alu ikagwiritsidwa ntchito molimbika kwambiri.

Mtengo wotsika: woyenera kupanga ma valve ooneka ngati ovuta kapena akuluakulu.

III. Kapangidwe ndi Kulemera

Valavu Yachitsulo Yopangidwa:

Kapangidwe kake ndi kosavuta, makamaka kofanana kapena kakang'ono. Kulemera kwake ndi kopepuka (pafupifupi 20% mpaka 30% kopepuka kuposa ma valve achitsulo opangidwa ndi zitsulo zomwezo).

Osewera Iron Wafer Gulugufe Vavu Ogulitsa China:

Nyumba zovuta (monga njira zapadera zoyendera madzi, matupi okhala ndi mabowo ambiri) zitha kupangidwa. Kulemera kwake kumakhala kwakukulu ndipo makulidwe a khoma nthawi zambiri amakhala okulirapo kuti akwaniritse kusowa kwa mphamvu.

IV. Mikhalidwe Yogwirira Ntchito Yoyenera

Valavu Yachitsulo Yopangidwa:

Makina amphamvu komanso otentha kwambiri: monga malo opangira magetsi, mafakitale a petrochemical, ndi mapaipi a nthunzi amphamvu kwambiri.

Malo otentha kwambiri: monga makina a gasi wachilengedwe wosungunuka (LNG), chitsulo chopangidwa chimakhala ndi kulimba kwabwinoko kwa kutentha kochepa.

Zinthu zoopsa: zamadzimadzi oopsa, zoyaka moto komanso zophulika (chifukwa chodalirika kwambiri).

Valavu Yoyang'ana Yotchinga Iron Yopangidwa ndi China:

Mikhalidwe yogwirira ntchito yachizolowezi yokhala ndi mphamvu yapakati ndi yotsika: monga kukonza madzi, mapaipi amafakitale, ndi nthunzi yotsika mphamvu.

Zowononga: Kukana dzimbiri kungawongoleredwe powonjezera zinthu za alloy (monga ma valve achitsulo chosapanga dzimbiri).

Ma valve akuluakulu: Pamene njira yopangira zinthu ndi yochepa, kuponyera zinthu kumakhala koyenera kwambiri pa ma valve akuluakulu.

V. Nthawi Yogulira ndi Kutumiza

Ma valve achitsulo opangidwa:Mtengo wokwera wa zinthu zopangira, ndalama zambiri zogulira zida zopangira ndi zida zopangira. Nthawi yayitali yopangira, yoyenera magulu ang'onoang'ono kapena zofunikira zapamwamba. Mitengo ya mayunitsi nthawi zambiri imakhala yokwera.

Ma valve achitsulo opangidwa ndi chitsulo:Mtengo wa nkhungu ndi wotsika, zomwe zimapangitsa kuti zikhale zoyenera kupanga zinthu zambiri. Nthawi yopangira ndi yochepa, ndipo mtengo wake ndi wopikisana kwambiri.

VI. Miyezo ndi Zizindikiro Zofanana

Valavu Yoyang'anira Yopangidwa ndi China:

Mafotokozedwe: ASTM A105 (chitsulo cha kaboni), A182 (chitsulo chosapanga dzimbiri), ndi zina zotero. Chizindikirocho nthawi zambiri chimakhala ndi mawu akuti "Yopangidwa".

Valavu ya Chipata cha Chitsulo Choponyedwa:

Mafotokozedwe: ASTM A216 (chitsulo cha kaboni), A351 (chitsulo chosapanga dzimbiri), ndi zina zotero. Chizindikirocho nthawi zambiri chimakhala ndi mawu akuti "Cast".
