1. Kusankha molakwika kwa zodzaza, zosagonjetsedwa ndi dzimbiri zapakatikati, zosagonjetsedwa ndi kuthamanga kwambiri kapena vacuum, kutentha kwakukulu kapena kutsika kwa kutentha kwavalavu ya butterfly;
2. Kulongedzako kumayikidwa molakwika, ndipo pali zolakwika monga kulowetsa zing'onozing'ono m'malo akuluakulu, ozungulira ozungulira, olimba pamwamba ndi pansi;
3. Chodzazacho chakalamba ndipo chataya mphamvu zake kuposa moyo wautumiki;
4. Kulondola kwa tsinde la valve sikwapamwamba, ndipo pali zolakwika monga kupindika, dzimbiri, ndi kuvala;
5. Chiwerengero cha mabwalo onyamula sichikwanira, ndipo chithokomiro sichimapanikizidwa mwamphamvu;
6. Gland, ma bolts, ndi mbali zina zawonongeka, kotero kuti gland sangathe kukanikizidwa mwamphamvu;
7. Kugwira ntchito molakwika, mphamvu zambiri, ndi zina zotero;
8. Gland imakhotakhota, ndipo kusiyana pakati pa gland ndi tsinde la valve ndi kakang'ono kwambiri kapena kwakukulu kwambiri, zomwe zimapangitsa kuti tsinde la valve liwonongeke komanso kuwonongeka kwa kulongedza.
njira yosamalira
1. Zida ndi mtundu wa zodzaza ziyenera kusankhidwa malinga ndi momwe ntchito ikugwirira ntchito;
2. Konzani bwino kulongedza molingana ndi malamulo oyenerera, kulongedza kumayenera kuikidwa ndi kuphatikizika chimodzi ndi chimodzi, ndipo chophatikiziracho chiyenera kukhala pa 30.°C kapena 45°C;
3. Kulongedza ndi moyo wautali wautumiki, ukalamba ndi kuwonongeka ziyenera kusinthidwa nthawi;
4. Pambuyo pa tsinde la valve likugwedezeka ndi kuvala, liyenera kuwongoleredwa ndi kukonzedwa, ndipo lowonongeka liyenera kusinthidwa nthawi;
5. Kuyikapo kuyenera kukhazikitsidwa molingana ndi chiwerengero cha kutembenuka kwachindunji, gland iyenera kumangirizidwa mofanana ndi mofanana, ndipo gland iyenera kukhala ndi kusiyana koyambirira kwa 5mm;
6. Zilonda zowonongeka, ma bolts ndi zigawo zina ziyenera kukonzedwa kapena kusinthidwa panthawi yake;
7. Njira zogwirira ntchito ziyenera kutsatiridwa, kupatulapo gudumu lothandizira, limagwira ntchito mofulumira komanso mphamvu yachibadwa;
8. Mitsempha ya gland iyenera kumangika mofanana ndi symmetrically. Ngati kusiyana pakati pa chithokomiro ndi tsinde la valve ndi kochepa kwambiri, kusiyana kwake kuyenera kuwonjezeka moyenerera; ngati kusiyana pakati pa gland ndi tsinde la valve ndi lalikulu kwambiri, liyenera kusinthidwa.
Gawo 3 Kutayikira kwa malo osindikizira
1. Malo osindikizira sakhala pansi ndipo sangathe kupanga mzere wapafupi;
2. Pakatikati pa kugwirizana pakati pa tsinde la valve ndi membala wotseka amaimitsidwa, olakwika kapena ovala;
3. Tsinde la valve ndi lopindika kapena losonkhanitsidwa molakwika, zomwe zimapangitsa kuti zigawo zotsekera zikhale zokhotakhota kapena kunja kwapakati;
4. Ubwino wa chinthu chosindikizira pamwamba sichimasankhidwa bwino kapena valve sichimasankhidwa malinga ndi momwe ntchito ikugwirira ntchito.
njira yosamalira
1. Sankhani moyenera zinthu ndi mtundu wa gasket malinga ndi momwe ntchito ikugwirira ntchito;
2. Kusintha mosamala ndi ntchito yosalala;
3. Mabotiwo ayenera kumangika mofanana ndi symmetrically. Ngati ndi kotheka, wrench ya torque iyenera kugwiritsidwa ntchito. Mphamvu yolimbikitsira isanakwane iyenera kukwaniritsa zofunikira ndipo isakhale yayikulu kapena yaying'ono. Payenera kukhala kusiyana pakati pa flange ndi kugwirizana kwa ulusi;
4. Msonkhano wa gasket uyenera kugwirizanitsidwa pakati, ndipo mphamvu iyenera kukhala yofanana. The gasket saloledwa kuti agwirizane ndi ntchito gaskets awiri;
5. Malo osindikizira osasunthika amakhala owonongeka, owonongeka, ndipo khalidwe lokonzekera silili lapamwamba. Kukonza, kugaya, ndi kuyendera mitundu kuyenera kuchitidwa kuti malo osindikizira a static akwaniritse zofunikira;
6. Mukayika gasket, samalani zaukhondo. Malo osindikizira ayenera kutsukidwa ndi palafini, ndipo gasket sayenera kugwa pansi.
Gawo 4. Kutayikira pamgwirizano wa mphete yosindikiza
1. Mphete yosindikiza siinakulungidwa mwamphamvu;
2. Mphete yosindikizira imalumikizidwa ndi thupi, ndipo mawonekedwe ake ndi otsika;
3. Ulusi wolumikiza, wononga ndi mphete yachitsulo ya mphete yosindikiza ndizotayirira;
4. Mphete yosindikiza imalumikizidwa ndikuwonongeka.
njira yosamalira
1. Pakuchucha pa malo osindikizira, zomatira ziyenera kubayidwa kenako ndikuzikulungiza ndikuzikonza;
2. Mphete yosindikiza iyenera kupangidwanso molingana ndi momwe kuwotcherera. Pamene kuwotcherera pamwamba sikungakonzedwe, kuwotcherera koyambirira ndi kukonza ziyenera kuchotsedwa;
3. Chotsani zitsulo, yeretsani mphete yokakamiza, m'malo mwa zigawo zowonongeka, perani malo osindikizira ndi mpando wolumikizira, ndikugwirizanitsa. Kwa magawo omwe ali ndi kuwonongeka kwakukulu kwa dzimbiri, akhoza kukonzedwa ndi kuwotcherera, kugwirizana ndi njira zina;
4. Kulumikiza pamwamba pa mphete yosindikizira ndi zowonongeka, zomwe zingathe kukonzedwa ndi kugaya, kugwirizanitsa, ndi zina zotero. Ngati sichikhoza kukonzedwa, mphete yosindikizira iyenera kusinthidwa.
Gawo 5. Kutayikira kumachitika pamene kutsekedwa kumagwa
1. Kusagwira bwino ntchito kumapangitsa kuti mbali zotsekera zitsekedwe ndipo zilumikizano ziwonongeke ndikusweka;
