Valve ibikoresho fatizo nka plaque yamashanyarazi, icyuma kimwe gitemba hamwe na piston valve yatangijwe muburyo burambuye

Valve ibikoresho fatizo nka plaque yamashanyarazi, icyuma kimwe gitemba hamwe na piston valve byamenyekanye muburyo burambuye Isahani yumuzunguruko wamavuta, icyuma kimwe gitemba hamwe na valve (ama piston valve) nikimwe mubice byingenzi bigize valve, uhite ufata igitutu cyakazi giciriritse, ibikoresho bisanzwe bikoreshwa bigomba kuba byujuje ibyangombwa by "umuvuduko wumuvuduko nubushyuhe". Ibyuma bya karubone: Bikwiranye nigitutu cyizina PN≤32.0MPa, ubushyuhe -30 ~ 425 ℃ amazi, amavuta, gaze, hydrogène, ammonia, azote na peteroli nibindi bitangazamakuru. Ibyiciro bisanzwe ni WC1, WCB, ZG25 nicyuma cyiza 20, 25, 30 hamwe nicyuma giciriritse 16Mn. Ibyuma bitarwanya aside, bikwiranye numuvuduko wizina PN≤6.4Mpa, ubushyuhe ≤200 ℃ sodium cyanide, acide glacial acetic acide nibindi bitangazamakuru ... Ibikoresho byinshi bibisi byo gukora no gukora ibice bya valve, harimo ibirango bitandukanye byurumuri ibyuma nibyuma byagaciro hamwe na aluminiyumu, ibikoresho bitandukanye bitari ibyuma. Ibikoresho bito byo gukora ibice bya valve bigomba gutoranywa ukurikije ibintu bikurikira: 1, umuvuduko ukabije wo gukora, ubushyuhe nibiranga. 2, ubushobozi bwo gutwara ibice kandi akenshi bigira uruhare muburyo bwa valve. 3. Imikorere myiza. 4. Hashingiwe ku kuzuza ibisabwa haruguru, birasabwa igiciro gito. Ibikoresho bito byamavuta yumuzunguruko wamavuta, icyuma kimwe gitemba hamwe na plaque (piston valve) Isahani yumuzunguruko wamavuta, icyuma kimwe gitemba hamwe na valve (ama piston valve) nikimwe mubice byingenzi bigize valve, uhita ufata igitutu cyakazi giciriritse, gikunze gukoreshwa ibikoresho fatizo bigomba kuba byujuje ingingo zijyanye n "" umuvuduko wa valve nubushyuhe ". Ibikoresho bisanzwe biri mubyiciro bikurikira: 1, icyuma cyumukara: icyuma cyumukara gikwiranye numuvuduko wizina PN≤1.0MPa, ubushyuhe -10 ℃ ~ 200 ℃ amazi, amavuta, gaze, gaze ya lisansi hamwe namavuta meza nibindi bitangazamakuru. Icyuma gisa nicyuma gisanzwe: HT200, HT250, HT300, HT350. Babiri, ibyuma byoroshye: bikwiranye numuvuduko wizina PN≤2.5MPa, ubushyuhe -30 ~ 300 ℃ amazi, amavuta, gaze na peteroli, ibicuruzwa bisanzwe ni: KTH300-06, KTH330-08, KTH350-10. Bitatu, guta imyanda: ibereye PN≤4.0MPa, ubushyuhe -30 ~ 350 ℃ amazi, amavuta, gaze namavuta nibindi bitangazamakuru. Ibirango bisanzwe ni: QT400 - 15, QT450 - 10, QT500 - 7. Kubera urwego rw'ikoranabuhanga rigezweho mu gihugu cyacu, inganda ni nziza kandi zimwe ni mbi kandi abakiriya ntiboroshye kubimenya. Ukurikije ubunararibonye, ​​birasabwa ko PN≤2.5MPa, valve cyangwa ibyuma bya valve byatoranijwe kubwumutekano. Bane, aside irwanya silicon ductile casting: ikwiranye numuvuduko wizina PN≤0.25MPa, ubushyuhe buri munsi ya 120 medium bubora. Bitanu, ibyuma bya karubone: bikwiranye numuvuduko wizina PN≤32.0MPa, ubushyuhe -30 ~ 425 ℃ amazi, amavuta, gaze, hydrogène, ammonia, azote nibikomoka kuri peteroli nibindi bitangazamakuru. Ibyiciro bisanzwe ni WC1, WCB, ZG25 nicyuma cyiza 20, 25, 30 hamwe nicyuma giciriritse 16Mn. Vi. Ibikoresho bivanze: Birakwiriye PN≤2.5MPa amazi, inyanja, O2, gaze, amavuta nibindi bitangazamakuru, hamwe nubushyuhe bwa -40 ~ 50 medium imyuka iciriritse, ibicuruzwa bisanzwe ni ZGnSn10Zn2 (amabati y'amabati), H62, HPB59-1 (umutuku umuringa), Qaz19-2, Qa19-4 (umuringa wa aluminium). Indwi, ikomeza ubushyuhe bwo hejuru cyane: ikwiranye numuvuduko wizina PN≤17.0MPA, ubushyuhe ≤570 heating gushyushya amavuta nibikomoka kuri peteroli. Ikirangantego gisanzwe gifite ZGCr5Mo, 1 cr5m0. ZG20CrMoV, ZG15Gr1Mo1V, 12 crmov WC6, WC9, nibindi. Umunani, ubushyuhe buke, bukwiranye numuvuduko wizina PN≤6.4Mpa, ubushyuhe ≥ -196 ℃ butadiene, pe, gaze gasanzwe, azote yamazi nibindi bitangazamakuru, ibirango bisanzwe) ni ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18Ni9 Icyenda, irwanya aside idafite umwanda. ibyuma, bikwiranye numuvuduko wizina PN≤6.4Mpa, ubushyuhe ≤200 ℃ sodium cyanide, acide acetike nibindi bitangazamakuru, ibirango bisanzwe ni ZG0Cr18Ni9Ti, ZG0Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, kurwanya aside hamwe na urea Ikibazo cya diameter ya nyuma yibeshya ya disiki na trapezoidal kugenzurwa kubera ubugari nuruhande rwimiterere yumuringa hamwe nicyuma cyuma cyibikoresho bya valve, bityo rero nta kwihanganira ibipimo bisabwa. Abatanga isoko kandi bagategeka gushyira mbere yo kugura ibikoresho, cyangwa ingano yibicuruzwa byashyizwemo imashini isagutse. Ibibyimba biterwa nimpande zidakabije, ibice byo gukubita, imashini ikubita, cyangwa kunyura hejuru yubuyobozi bupfa bipfa gupfa biremewe igihe cyose byavanyweho mugihe cyo gutunganya cyangwa ntibibi bikaguma mubicuruzwa byarangiye (G1, G2, G3, na G4 muri FIG. Igishushanyo kigomba kwerekana ko impande nkizo zitagomba kurenga mm 1.5 Guhuza: Gutera ibyuma byumuringa nibikoresho bivangwa nibikoresho bya valve (II) Amakosa yikigereranyo muri no gupfa - gutandukanya imirongo Itsinda ryibikoresho I, ibisobanuro, na t bigomba guhuza urwego rwo gutandukana rwatanzwe mu mbonerahamwe ya 14, mugihe itsinda ryibikoresho fatizo Ⅱ bigomba guhuza nimbonerahamwe ya 15, itsinda ryibikoresho fatizo Ⅲ Ibisobanuro binini byo kubara Inguni, tmax, ni igipimo cyibanze cyo kwihanganira ibipimo biboneka murwego rwo gutandukanya umurongo.
