Nibihe bidasanzwe bisabwa kugirango uhitemo igiti cya valve

Ibikoresho byo gukora ibice bya valve bigomba gutoranywa ukurikije ibintu bikurikira:

1. Umuvuduko, ubushyuhe nibiranga uburyo bukora.

2. Imbaraga z'igice n'imikorere yacyo muriindangaimiterere.

3. Ifite umusaruro mwiza.

4. Niba ibisabwa haruguru byujujwe, hagomba kubaho igiciro gito.

Ibikoresho by'ibiti

Mugihe cyo gufungura no gufunga valve, uruti rwa valve rufite imbaraga zo guhagarika umutima, igitutu na torsion, kandi riba rihuye nuburyo bworoshye.Igihe kimwe, hariho umuvuduko wo guterana amagambo hamwe no gupakira.Kubwibyo, ibikoresho bya valve bigomba kuba bihagije kubushyuhe bwagenwe.Imbaraga n'ingaruka zikomeye, urwego runaka rwo kurwanya ruswa no kurwanya ibishushanyo, hamwe nibikorwa byiza.

Bikunze gukoreshwa nibikoresho bya valve nibi bikurikira.

1. Ibyuma bya karubone

Iyo ikoreshejwe mumazi no mumazi hamwe numuvuduko muke hamwe nubushyuhe bwo hagati butarenga 300 ℃, A5 ibyuma bisanzwe bya karubone bikoreshwa.

Iyo ikoreshejwe mumazi hamwe nicyuka hamwe nigitutu giciriritse hamwe nubushyuhe bwo hagati butarenga 450 ℃, ibyuma 35 byujuje ubuziranenge bikoreshwa muri rusange.

2. Kuvanga ibyuma

40Cr (ibyuma bya chrome) isanzwe ikoreshwa mugihe ikoreshwa kumuvuduko wo hagati hamwe numuvuduko mwinshi, kandi ubushyuhe bwo hagati ntiburenga 450 ℃ mumazi, amavuta, peteroli nibindi bitangazamakuru.

38CrMoALA ibyuma bya nitriding birashobora gukoreshwa mugihe bikoreshejwe mumazi, amavuta hamwe nibindi bitangazamakuru bifite umuvuduko mwinshi nubushyuhe bwo hagati butarenga 540 ℃.

25Cr2MoVA chromium molybdenum vanadium ibyuma bikoreshwa mubisanzwe iyo bikoreshejwe mumashanyarazi yumuvuduko mwinshi hamwe nubushyuhe bwo hagati butarenga 570 ℃.

Bitatu, ibyuma birwanya aside

Ikoreshwa mubitangazamakuru bitangirika kandi byangirika bifite itangazamakuru ryumuvuduko ukabije hamwe numuvuduko mwinshi, kandi ubushyuhe bwo hagati ntiburenga 450 ° C.1Cr13, 2Cr13, 3Cr13 chromium ibyuma bitagira umwanda birashobora gutoranywa.

Iyo ikoreshejwe mubitangazamakuru byangirika, ibyuma birwanya aside nka Cr17Ni2, 1Cr18Ni9Ti, Cr18Ni12Mo2Ti, Cr18Ni12Mo3Ti, na PH15-7Mo mvura igwa ibyuma bishobora gukomera.

Icya kane, ibyuma birwanya ubushyuhe

Iyo ikoreshejwe kubushyuhe bwo hejuru cyane ubushyuhe bwo hagati butarenga 600 ℃, 4Cr10Si2Mo martensitike ibyuma birwanya ubushyuhe hamwe na 4Cr14Ni14W2Mo ibyuma bishobora kwihanganira ubushyuhe bwa austenitike.
