Valavu ya Gulugufe Yopatukana Kawiri vs Valavu ya Gulugufe Yopatukana Katatu？

Kodi pali kusiyana kotani pakati pa valavu ya gulugufe ya eccentric iwiri ndi ya eccentric katatu?

Pa ma valve a mafakitale, ma valve a gulugufe awiri osasunthika komanso ma valve a gulugufe atatu osasunthika angagwiritsidwe ntchito pochiza mafuta ndi gasi, mankhwala ndi madzi, koma pakhoza kukhala kusiyana kwakukulu pakati pa mitundu iwiriyi ya ma valve a gulugufe, kotero ndikofunikira kudziwa kusiyana pakati pa mitundu iwiriyi ya ma valve kuti musankhe bwino.

Munkhaniyi, tiona kusiyana kwakukulu pakati pamavavu awiri a gulugufendimavavu atatu a gulugufekomanso ubwino wawo ndi ntchito zawo.

Choyamba, kapangidwe ndi kapangidwe kake ndi zosiyana.

Disiki yavalavu ya gulugufe iwiri yosiyanaIli pakati pa thupi la valavu ndi shaft. Kapangidwe kake ka offset kamathandiza kukangana ndi kuwonongeka kwa mpando wofewa wa valavu potsegula ndi kutseka, motero kumawonjezera nthawi yogwira ntchito ndikuwonjezera kutseka. Ngakhale valavu ya gulugufe yotchedwa triple eccentric ili ndi valavu yachitatu yosiyana pamwamba pa valavu iwiri yosiyana, mwachitsanzo, imapanga mawonekedwe a conical pamwamba pa kutseka, ndipo zinthu zomwe zili pamwamba pa kutseka nthawi zambiri zimakhala kutseka kwachitsulo, zomwe zimapangitsa kuti kutseka kukhale kolimba komanso kusakanikirana kochepa, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamavuto akulu komanso kutentha kwambiri.

Chachiwiri, magwiridwe antchito ndi osiyana.

Ma valve atatu a gulugufe ozunguliraamapereka zabwino zingapo kuposa mapangidwe awiri osagwirizana ndi mawonekedwe. Kapangidwe ka katatu kosagwirizana ndi mawonekedwe kamapereka chisindikizo chotseka mpweya, zomwe zikutanthauza kuti kutayikira kumatha kupewedwa bwino ngakhale pansi pa kupsinjika kwakukulu komanso kutentha kwambiri. Chifukwa chake ndi koyenera kwambiri pa ntchito zofunika kwambiri zomwe zimafuna kutsekedwa mwamphamvu. Kuphatikiza apo, kapangidwe ka chivundikiro cha valavu ya gulugufe ya katatu kosagwirizana ndi mawonekedwe kamapangitsa kuti kukana kusweka kukhale kokulirapo kuti nthawi yokonza ipitirire komanso ndalama zokonzera zichepe. Ubwino uwu umapangitsa valavu ya gulugufe ya katatu kukhala chisankho choyamba chogwiritsidwa ntchito molimbika m'mafakitale amafuta ndi gasi, petrochemical ndi kupanga magetsi.

Pomaliza, thMtengo womangira sunagwiritsidwe ntchito.

Ubwino waukulu wavalavu ya gulugufe iwiri yosiyanaPoyerekeza ndi valavu ya gulugufe ya katatu, mtengo wake ndi wotsika pang'ono. Ngati mikhalidwe yogwirira ntchito sikufuna valavu ya gulugufe ya katatu yokhazikika komanso yolimba kwambiri, valavu ya gulugufe ya katatu yokhazikika ndi chisankho chotsika mtengo. Izi zili choncho chifukwa mavalavu a gulugufe awiri okhazikika ndi oyenera kugwiritsidwa ntchito pogwiritsa ntchito kupsinjika ndi kutentha kochepa mpaka kwapakati. Kugwira ntchito kwawo kodalirika komanso kugwiritsa ntchito bwino ndalama kumapangitsa kuti akhale chisankho chodziwika bwino pa ntchito zosiyanasiyana zamafakitale.

Pomaliza, kusankha pakati pa ziwiri ndimavavu atatu a gulugufe ozunguliraZimadalira zofunikira za sing'anga ndi chilengedwe. Ma valve a gulugufe atatu ozungulira ndi oyenera mikhalidwe yomwe imafuna kutsekedwa kwambiri komanso kukana kupsinjika kwakukulu ndi kutentha, pomwe ma valve awiri ozungulira amapereka njira yotsika mtengo yogwiritsira ntchito mosavuta.
