Kodi pali kusiyana kotani pakati pa valavu yosindikizira yofewa ndi valve yosindikizira yolimba

Malinga ndi zosindikiza pamwamba,ma valve pachipataakhoza kugawidwa m'mitundu iwiri: chisindikizo cholimba ndi chisindikizo chofewa.Kodi pali kusiyana kotani pakati pa valavu yosindikizira yofewa ndi valavu yosindikizira yolimba:
Valavu yosindikizira pachipata: Zida zosindikizira pamalo onse osindikizira ndi zida zachitsulo, zomwe zimatchedwa "chisindikizo cholimba".Kukana kutentha kwakukulu, kukana kuvala, zinthu zabwino zamakina monga: chitsulo + chitsulo;chitsulo + mkuwa;zitsulo
+ Graphite;chitsulo + aloyi chitsulo.Zida zosindikizira zomwe zimagwiritsidwa ntchito nthawi zambiri ndi: 13Cr zitsulo zosapanga dzimbiri, zida zolimba zolimba zolimba, tungsten carbide, etc.
Valavu yotsekera pachipata: chosindikiziracho chimapangidwa ndi zitsulo mbali imodzi ndi zotanuka zopanda zitsulo mbali inayo, zomwe zimatchedwa "chisindikizo chofewa".Kusindikiza kwa mtundu uwu wa chisindikizo ndikwabwino, koma sikulimbana ndi kutentha kwakukulu, kosavuta kuvala, komanso kumakhala ndi makina osowa.Monga: chitsulo + mphira;zitsulo + PTFE, etc. Zikutanthauza kuti mbali imodzi ya awiri chisindikizo amapangidwa ndi zipangizo ndi otsika kuuma.Nthawi zambiri, mpando wosindikizira wofewa umapangidwa ndi zinthu zopanda zitsulo zomwe zimakhala ndi mphamvu, kuuma komanso kutentha.Ili ndi ntchito yabwino yosindikiza ndipo imatha kutulutsa zero, koma imakhala ndi moyo wautali.Poyerekeza ndi kusasinthika kosasinthika kwa kutentha, chisindikizo cholimba chimapangidwa ndi chitsulo, ndipo kusindikiza kumakhala kocheperako, ngakhale opanga ena amati imatha kutulutsa zero.Cholinga cha kupangidwa kwa valavu yosindikizira pachipata: kuthetsa vuto la mpando wa valavu ndi kusindikiza pamwamba pa mbale ya valavu yomwe ili ndi dzimbiri kapena kupunduka, mbale ya valve imatha kubwezera chivundikiro cholimba ndi kuthamanga kwachangu valavu yotsekemera yotsekemera, ndikuthetsa vuto la zinthu zofewa zotsekemera zowonongeka ndi kukangana.
Zothandiza zamitundu yofewa yosindikizira pachipata: m'mimba mwake (p50-p400mm, kuthamanga kwa 2.5-4.0MPa, zakumwa zoziziritsa kukhosi zosiyanasiyana zosakwana 200 ℃).
Chisindikizo chofewa sichingathe kukwaniritsa zofunikira pazitsulo zina zowononga, ndipo chisindikizo cholimba chikhoza kuthetsa!
Mitundu iwiriyi ya zisindikizo imatha kuthandizirana.Pankhani yolimba, chisindikizo chofewa ndi chabwino, koma tsopano kulimba kwa chisindikizo cholimba kungathenso kukwaniritsa zofunikira zomwezo!Ubwino wa chisindikizo chofewa ndikuchita bwino kusindikiza, koma kuipa kwake ndikuti ndikosavuta kukalamba, kuvala, komanso kukhala ndi moyo waufupi wautumiki.Chisindikizo cholimba chimakhala ndi moyo wautali wautumiki, koma kumangika kumakhala koipitsitsa kuposa kusindikiza kofewa.
