Gasi valve, silinda yekuchenesa matanho general valve carbon steel forging technical conditions Kucheneswa kwevharuvhu yegasi nesimbi silinda vharuru chinhu chimwe chinofanira kuitwa pamberi pekubatanidza zvikamu uye zvikamu zvevharuvhu. Iyi nzira inogona kupedzwa kuburikidza nematanho akati wandei. Kana paine kuregeredza mumatanho aya, zvinokwanisika kukonzeresa njodzi dzakavanzika mukushandiswa kweramangwana. Kucheneswa kwevhavha yegesi uye simbi cylinder valve chinhu chimwe chinofanira kuitwa pamberi pekusangana kwezvikamu uye zvikamu zvevhavha. Iyi nzira inogona kupedzwa kuburikidza nematanho akati wandei. Kana paine kuregeredza mumatanho aya, zvinokwanisika kukonzeresa njodzi dzakavanzika mukushandiswa kweramangwana. Kuchenesa maitiro egasi mavharuvhu nemasilinda Matanho akananga: 1. Maererano nezvinodiwa zvekugadzirisa, zvimwe zvikamu zvinoda kukwenenzverwa pasina kugadzirisa mabhura pamusoro pepamusoro Zvikamu zvose zvakasvibiswa 3. Pickling passivation inoitwa mushure mekudzikisa, uye mumiririri wekuchenesa haaiti. zvine phosphorus 4 Mushure me pickling passivation, sukurudza nemvura yakachena, pasina mishonga inosara, carbon steel parts siya danho iri 5 Pukuta zvikamu chimwe nechimwe nemucheka usina kurukwa. Usasiye pamusoro pezvikamu neshinda yewaya kana kuputira yakaoma nenitrogen yakachena 6 Pukuta zvikamu chimwe nechimwe nemucheka usina kuruka kana bepa resefa rakanatswa nedoro rekuongorora kusvika pasisina ruvara. Verenga nhanho dziri pamusoro, ndinotenda kuti wakanzwisisa, hunhu, chengetedzo zviyero zvevhavhavhavhavha, mune zvese zvinongedzo kuita zvine hungwaru, nekuti chete nenzira iyi ndiko kuchengetedza kwemushandisi uye bhizinesi revatengi rine mutoro! Tekinoroji Mamiriro ezvinhu ecarbon simbi forgings yeakajairwa mavharuvhu, flanges, pombi fittings uye zvimwe compression kabhoni simbi forgings zvinodiwa, nzira dzekuyedza, mitemo yekuongorora, zvinodiwa zvekuodha, mamaki uye zvitupa zvemhando. Iyo ingot ichava nemagumo akakwana ekucheka kudzivirira kukanganisa kunokuvadza (kusanganisira shrinkage, kupatsanurwa, kupeta, nezvimwewo). Forging ichave nechokwadi chekuchinja kuzere kweiyo forgings kusangana nedhizaini uye tekinoroji zvinodiwa. Panguva yekugadzira, mafogi anofanirwa kuve nechokwadi kuti anotonhorera zvishoma nezvishoma sezvaanopfuura nepachikamu chekuchinja tembiricha. Mushure mekunge kuumbwa kwekupedzisira kuumbwa, kunofanirwa kutonhodzwa kusvika pazasi 500 ℃ isati yataurwa yekupisa kurapwa isati yaitwa. Chiyero cheIchi chiyero chinotsanangura zvinodikanwa, nzira dzekuyedza, mitemo yekuongorora, zvinodiwa zvekuodha, mamaki uye zvitupa zvemhando yepamusoro yekumanikidza kabhoni simbi forgings senge mavharuvhu, flanges uye pombi fittings. Iyi chiyero inoshanda kune akajairwa compression kabhoni simbi forgings senge mavharuvhu, flanges uye pombi fittings (pano inonzi forgings). Kwete - compression forgings inogona kuitwa nereferensi. Normative referensi gwaro Aya anotevera magwaro anoumba mazwi eiyi chiyero nekutarisa kune huni Standard. Zvese zvinozogadziridzwa (zvisingasanganisire errata) kana zvigadziriso kumagwaro ataurwa panguva yechiziviso hazvishande kune iyi chiyero. Nekudaro, mapato ari muchibvumirano pasi pehuni Standard anokurudzirwa kuti aongorore kushandiswa kweiyi shanduro dzemagwaro. Kune mareferensi asina kunyorwa, mavhezheni avo anoshanda kune iyi mwero.
