Malangizo oyika kwa mavavu a mpira opangidwa ndi flanged Zofunikira paukadaulo pakukhazikitsa ndikugwiritsa ntchito mavavu amagetsi amagetsi

Malangizo oyika mavavu a mpira wa flanged Zofunikira paukadaulo pakuyika ndi kugwiritsa ntchito mavavu amafuta otsekemera 1. The perpendicularity ya flange pamwamba pa chitoliro ndi mzere wapakati wa chitoliro ndi cholakwika cha dzenje la bawuti la flange ziyenera kukhala mkati mwazololedwa. mtengo. Vavu ndi mzere wapakati wa mapaipi ziyenera kukhala zofananira musanayike. 2. Mukamangirira mabawuti, gwiritsani ntchito wrench yofanana ndi nati. Mukamagwiritsa ntchito kukakamiza kwamafuta ndi zida za pneumatic zomangirira, samalani kuti musapitirire ma torque omwe atchulidwa. 3. Pogwirizanitsa ma flanges awiri, choyamba, chosindikizira cha flange pamwamba ndi gasket chiyenera kukanikizidwa mofanana, kuti zitsimikizire kuti flange imagwirizanitsidwa ndi kupsinjika komweko kwa bolt. 4. Kumangirira kwa flange kuyenera kupeŵa mphamvu yosagwirizana, ndipo kuyenera kumangirizidwa motsatira malangizo a symmetry ndi mphambano. 5. Pambuyo poika flange, onetsetsani kuti ma bolts ndi mtedza onse amangiriridwa mofanana. 6, kumangirira ma bolts ndi mtedza, pofuna kupewa kumasula chifukwa cha kugwedezeka, kugwiritsa ntchito ma washer. Pofuna kupewa kumamatira pakati pa ulusi pa kutentha kwakukulu, zigawo za ulusi ziyenera kuphimbidwa ndi anti-adhesion agent pakuyika. 7. Amagwiritsidwa ntchito pazitsulo zotentha kwambiri kuposa 300 ℃. Kutentha kukakwera, mabawuti olumikizirana ndi flange, mabawuti omangira chivundikiro cha ma valve, zosindikizira zosindikizira ndi ma bolts onyamula zithowa ziyenera kumangidwanso. 8, valavu yotsika kutentha imayikidwa m'malo a kutentha kwa mlengalenga, chifukwa cha kusiyana kwa kutentha, flange, gasket, bolts ndi mtedza zimachepa, ndipo chifukwa chakuti zigawozi siziri zofanana 9, chiwerengero cha kukula kwa mzere ndi komanso zosiyana, kupanga zosavuta kwambiri kutayikira zinthu zachilengedwe. Kuchokera pazifukwa izi, pomangirira ma bolts pa kutentha kwamlengalenga, torque yomwe imaganizira za kugunda kwa gawo lililonse pa kutentha kochepa iyenera kutengedwa. 1. Musanakhazikitse, chipinda chamkati cha LPG valve chiyenera kutsukidwa ndipo zolakwika zomwe zimayambitsidwa ndi kayendedwe ziyenera kuchotsedwa; 2. Kuyika valavu ya LPG kuyenera kusunga shaft ya gulugufe kukhala yopingasa ndi valavu ya pistoni molunjika pamwamba; 3. Musanagwiritse ntchito valavu ya LPG, chipangizo chotumizira chiyenera kusinthidwa kuti chisamalire ntchito za chipangizo chopatsirana, ndipo malire a sitiroko ndi kuwongolera chitetezo cha torque ndi odalirika; 4. Mafuta opaka mafuta ayenera kuwonjezeredwa mokwanira asanatumize ndikugwiritsa ntchito gawo lililonse lopaka mafuta pa chipangizo chotumizira ma valve a LPG; 5. Musanayambe chipangizo chamagetsi, bukhu la chipangizo chamagetsi cha valve ya gasi ya liquefied liyenera kuwerengedwa mosamala.
