Kusindikiza pamwamba
Malo osindikizira ndiye mbali yofunika kwambiri yogwirira ntchito ya valve. Ubwino wa malo osindikizira umagwirizana ndi moyo wautumiki wa valve. Nthawi zambiri, zinthu zosindikizira pamwambazi ziyenera kuganizira za kukana kwa dzimbiri, kukana kwa abrasion, kukana kukokoloka, kukana kwa okosijeni ndi zinthu zina.
Nthawi zambiri pamakhala magulu awiri akulu:
(1) Zinthu zofewa
1, labala (kuphatikiza mphira wa butadiene, labala wa fluorine, etc.)
2, pulasitiki (PTFE, nayiloni, etc.)
(2) zomangira zolimba
1, aloyi yamkuwa (kwa valve low pressure)
2, chromium chitsulo chosapanga dzimbiri (cha valve yamphamvu kwambiri)
3, Sitai alloy (kwa kutentha kwambiri ndi ma valve othamanga kwambiri ndi mavavu amphamvu owononga)
4. Nickel base alloy (ya corrosive media)
Zida za tsinde
Tsinde limakhala ndi mphamvu zokoka, kukanikiza ndi torsional panthawi yotsegula ndi kutseka ma valve, ndipo imakhudzana mwachindunji ndi sing'anga pamene
Palinso NTCHITO ZOYAMBIRA ZOTHANDIZA PAKATI NDI KUTENGA, CHOCHOKERA CHINTHU CHIYENERA KUKHALA NDI MPHAMVU YOKHALIRA NDIKUTHANDIZANI PA KUTENGERA KWANKHANI.
Kulimba, kukana dzimbiri ndi kukana abrasion, ndiukadaulo wabwino.
Zida zodziwika bwino za tsinde ndi izi.
Choyamba, carbon steel
Ikagwiritsidwa ntchito m'madzi ndi sing'anga yotentha yotsika komanso kutentha kwapang'onopang'ono kosapitilira 300 ℃, chitsulo cha A5 wamba chimasankhidwa.
Pakuti kuthamanga sing'anga ndi kutentha sing'anga si upambana 450 ℃ madzi, sing'anga nthunzi, zambiri kusankha 35 khalidwe mpweya zitsulo.
Awiri, aloyi chitsulo
Pakuti kuthamanga sing'anga ndi kuthamanga kwambiri, sing'anga kutentha si upambana 450 ℃ madzi, nthunzi, mafuta ndi TV zina, zambiri kusankha 40Cr (chromium chitsulo).
Pakuti kuthamanga kwambiri, sing'anga kutentha si upambana 540 ℃ madzi, nthunzi ndi TV zina, kusankha 38CrMo>
Pakuti kuthamanga kwambiri, sing'anga kutentha si upambana 570 ℃ nthunzi sing'anga, zambiri kusankha 25Cr2MoVA chromium molybdenum vanadium zitsulo.
Chachitatu, chitsulo chosapanga dzimbiri cha asidi
Kwa kuthamanga kwapakati komanso kuthamanga kwambiri, kutentha kwapakati sikudutsa 450 ℃ sing'anga yosawononga komanso yofooka yowononga, mutha kusankha 1Cr13, 2Cr13, 3Cr13 chromium chitsulo chosapanga dzimbiri. Kwa media zowononga, Cr17Ni2, 1Cr18Ni9Ti, Cr18Ni12Mo2Ti, Cr18Ni12Mo3Ti ndi zitsulo zina zosapanga dzimbiri zosapanga asidi ndi PH15-7mO zitsulo zowumitsa mpweya zitha kusankhidwa.
Zinayi, zitsulo zosagwira kutentha
4Cr10Si2Mo Martensite mtundu zitsulo zosagwira kutentha ndi zitsulo zingagwiritsidwe ntchito pamene kutentha kwapakati sikupitirira 600 ℃
4Cr14Ni14W2Mo Austenitic mtundu wosagwira zitsulo.
Mtedza wa tsinde
Mtedza wa tsinde umayikidwa mwachindunji ku mphamvu ya axial ya tsinde panthawi yotsegula ndi kutseka kwa valve choncho iyenera kukhala ndi mphamvu zinazake. Panthawi imodzimodziyo, imapangidwa ndi tsinde, yomwe imafunikira kagawo kakang'ono ka mikangano, palibe dzimbiri ndi kupewa chodabwitsa cha kuluma.
Choyamba, aloyi yamkuwa
Coefficient ya Copper alloy friction ndi yaying'ono, yopanda dzimbiri, ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri. Kwa PG1.6mpa low pressure valves ZHMN58-2-2 cast brass ingagwiritsidwe ntchito. Kwa PG16-6.4mpa sing'anga kuthamanga valve angagwiritse ntchito ZQ>
Chachiwiri, chitsulo
Pamene zinthu ntchito salola ntchito aloyi mkuwa, akhoza kusankha 35, 40 khalidwe carbon zitsulo, 2Cr13, 1Cr18Ni9, Cr17Ni2 ndi zina zosapanga dzimbiri asidi zosagwira zitsulo.
Ntchito zogwirira ntchito siziloledwa kutanthauza zotsatirazi.
1, valavu yamagetsi, mtedza wa valavu wokhala ndi mavwende clutch, uyenera kutenthedwa kuti upeze kuuma kwakukulu kapena kuuma kwa pamwamba.
2, sing'anga yogwirira ntchito kapena malo ozungulira si oyenera kusankha aloyi yamkuwa, monga dzimbiri lamkuwa la ammonia sing'anga. Posankha mtedza wa tsinde lachitsulo, chidwi chapadera chiyenera kuperekedwa pazochitika za kuluma kwa ulusi.
Zaka zingapo zikubwerazi zidzakhala nthawi yothamanga kwambiri yamakampani a valve, zotsatira zachindunji za kugwedezeka kwakukulu kumeneku ndizochitika zamakono za polarization mu kampu ya mtundu wa valve cabinet kuti ikule.
Zikuyembekezeka kuti m'zaka zingapo zikubwerazi zitha kupulumuka mumsika mabizinesi avalavu sakhala ochuluka.
Koma makampani opanga ma valve kugwedezeka kwakukulu kumeneku kudzabweretsa mwayi waukulu, zotsatira zododometsa zidzapangitsa kuti msika ukhale womveka bwino.
