Kodi Kukonza mavavu akutuluka?

Ngati valavu ikutha, choyamba tiyenera kupeza chomwe chimayambitsa kuvunda kwa valve, ndiyeno pangani ndondomeko yokonza valve malinga ndi zifukwa zosiyanasiyana.Zotsatirazi ndi zomwe zimayambitsa komanso njira zothetsera ma valve.

1.Kutuluka kwa Thupi ndi Boneti

Chifukwa:

①Mkhalidwe woponyera siwokwera, ndipo thupi ndi boneti zili ndi zolakwika monga matuza, mawonekedwe otayirira ndi kuphatikiza kwa slag;

② kuzimitsa kusweka;

③ Kuwotcherera kosakwanira, pali zolakwika monga kuphatikizika kwa slag, kusawotcherera, ming'alu yamavuto, ndi zina zambiri;

④Vavu yachitsulo imawonongeka itagundidwa ndi chinthu cholemera.

Njira yosamalira:

① Sinthani mtundu wakuponya, ndikuyesa mphamvu motsatira malamulo musanakhazikitse;

②Kwa ma valve omwe amagwira ntchito ndi kutentha kochepa monga 0 ° C kapena pansi pa 0 ° C, kuteteza kutentha kapena kusakaniza kuyenera kuchitika, ndipo ma valve omwe sagwiritsidwa ntchito ayenera kukhetsedwa ndi madzi owunjika;

③ The kuwotcherera msoko wa valavu thupi ndi bonati wapangidwa kuwotcherera zidzachitika molingana ndi zoyenera kuwotcherera malamulo ntchito, ndi kudziwika chilema ndi mayeso mphamvu zidzachitika pambuyo kuwotcherera;

④ Ndizoletsedwa kukankhira ndi kuyika zinthu zolemera pa valve, ndipo siziloledwa kugunda zitsulo zotayidwa ndi ma valve opanda zitsulo ndi nyundo yamanja.Kuyika mavavu akulu akulu ayenera kukhala ndi mabulaketi.

2. Kutayikira pa Kulongedza

Kutayikira kwa valve, Chifukwa chachikulu ndikutuluka kwapang'onopang'ono.

Chifukwa:

①Kunyamula sikunasankhidwe moyenera, sikumalimbana ndi dzimbiri, ndipo sikumalimbana ndi kugwiritsa ntchito kuthamanga kwambiri kapena vacuum, kutentha kwambiri kapena kutentha kwa valve;

②Kunyamula kumayikidwa molakwika, ndipo pali zolakwika monga kusintha chachikulu ndi chaching'ono, cholumikizira chopindika ndi choyipa, cham'mwamba chimakhala cholimba ndipo chapansi ndi chomasuka;

③Phukusili lakalamba ndipo lataya mphamvu zake chifukwa ladutsa moyo wake wautumiki;

④Kulondola kwa tsinde la valve sikwapamwamba, ndipo pali zolakwika monga kupindika, dzimbiri ndi kuvala;

⑤ Chiwerengero cha mabwalo onyamula sichikwanira, ndipo chithokomiro sichimapanikizidwa mwamphamvu;

⑥ The gland, bolts, ndi mbali zina zawonongeka, kotero kuti gland sangathe kupsinjidwa;

⑦ Kugwira ntchito molakwika, kukakamiza kwambiri, ndi zina zotero;

⑧ Gland imakhotakhota, ndipo kusiyana pakati pa gland ndi tsinde kumakhala kochepa kwambiri kapena kwakukulu kwambiri, zomwe zimapangitsa kuti tsinde liwonongeke komanso kuwonongeka kwa kulongedza.

Njira yosamalira:

①Zinthu ndi mtundu wa kulongedza ziyenera kusankhidwa malinga ndi momwe amagwirira ntchito;

②Kunyamula kuyenera kukhazikitsidwa moyenera molingana ndi malamulo oyenera, kulongedzako kumayenera kuyikidwa ndikukanikizidwa chimodzi ndi chimodzi, ndipo cholumikiziracho chiyenera kukhala pa 30 ℃ kapena 45 ℃;

③ Zonyamula zomwe zakhala zikugwiritsidwa ntchito kwa nthawi yayitali, zokalamba komanso zowonongeka ziyenera kusinthidwa munthawi yake;

④tsinde liyenera kuwongoleredwa ndi kukonzedwa litapindika ndi kuvala, ndipo zomwe zawonongeka kwambiri ziyenera kusinthidwa pakapita nthawi;

⑤ Kuyikako kumayenera kukhazikitsidwa molingana ndi kuchuluka kwa matembenuzidwe omwe atchulidwa, chithokomirocho chizimitsidwa molingana komanso molingana, ndipo manja oponderezedwa ayenera kukhala ndi chilolezo cholimba chopitilira 5mm;

⑥ Zotupa zowononga, mabawuti ndi zigawo zina ziyenera kukonzedwa kapena kusinthidwa munthawi yake;

⑦ Njira zogwirira ntchito ziyenera kutsatiridwa, kupatulapo gudumu lamanja, limagwira ntchito ndi liwiro lokhazikika komanso mphamvu yanthawi zonse;

⑧ Maboti a gland ayenera kumangika mofanana komanso molingana.Ngati kusiyana pakati pa chithokomiro ndi tsinde kuli kochepa kwambiri, kusiyana kwake kuyenera kuwonjezeka moyenerera;ngati kusiyana pakati pa gland ndi tsinde ndi lalikulu kwambiri, liyenera kusinthidwa.

3. Kutaya kwa malo osindikizira

Chifukwa:

① Malo osindikizira ndi osafanana ndipo sangathe kupanga mzere wothina;

②Pakatikati pa kugwirizana pakati pa tsinde la valve ndi gawo lotseka layimitsidwa, lolakwika kapena lovala;

③ Tsinde la valavu limapindika kapena kusanjidwa molakwika, zomwe zimapangitsa kuti gawo lotseka likhoteke kapena kusayanjanitsidwa;

④ Ubwino wa zinthu zosindikizira pamwamba zimasankhidwa molakwika kapena valavu sichimasankhidwa malinga ndi momwe ntchito ikugwirira ntchito.

Njira yosamalira:

①Malinga ndi momwe amagwirira ntchito, zida ndi mtundu wa gasket zimasankhidwa bwino;

②Kusintha mosamala, kugwira ntchito mosalala;

③ Maboti amayenera kumangidwa 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 chilolezo cholimba chisanadze pakati pa flange ndi kugwirizana kwa ulusi;

④Msonkhano wa gasket uyenera kulumikizidwa pakati, ndipo mphamvuyo ikhale yofanana.The gasket saloledwa kuti agwirizane ndi ntchito gaskets awiri;

⑤ Ngati malo osindikizira osasunthika achita dzimbiri, awonongeka, ndipo khalidwe lokonzekera silili lalitali, liyenera kukonzedwa, pansi, ndikuyang'aniridwa kuti likhale lopaka utoto, kuti malo osindikizira a static akwaniritse zofunikira;

⑥ Samalirani kuyeretsa mukayika gasket, malo osindikizira ayenera kutsukidwa ndi palafini, ndipo gasket sayenera kugwa pansi.

4. Kutayikira pamgwirizano wa mphete yosindikiza

Chifukwa:

① mphete yosindikizira siinakulungidwa mwamphamvu;

②Mphete yosindikizira imalumikizidwa ndi thupi, ndipo mawonekedwe ake ndi osauka;

③Ulusi wolumikizira, wononga ndi mphete yosindikizira ndizomasuka;

④Kulumikizana kwa mphete yosindikizira kwachita dzimbiri.

Njira yosamalira:

①Kutayikira pamalo osindikizira ndi kugudubuza kuyenera kubayidwa ndi zomatira ndikukhazikika ndikugudubuza;

② mphete yosindikizira iyenera kuwotchereranso molingana ndi momwe kuwotcherera.Ngati kuwotcherera kwapang'onopang'ono sikungakonzedwe, kuwotcherera koyang'ana koyambira ndi kukonza kumachotsedwa;

③Chotsani wononga ndi kusindikiza mphete, yeretsani, sinthani mbali zowonongeka, perani malo osindikizira pakati pa chisindikizo ndi mpando wolumikizira, ndikugwirizanitsanso.Kwa magawo omwe ali ndi kuwonongeka kwakukulu kwa dzimbiri, akhoza kukonzedwa ndi kuwotcherera, kugwirizana ndi njira zina;

④Kulumikizana kwa mphete yosindikizira kumakhala ndi dzimbiri ndipo kumatha kukonzedwa ndikupera, kulumikiza ndi njira zina.Ngati sichikhoza kukonzedwa, mphete yosindikizira iyenera kusinthidwa.

5. Gawo lotsekera limagwa ndikutuluka

Chifukwa:

①Opaleshoniyo ndi yosauka, kotero kuti gawo lotsekera limakhala lokhazikika kapena kupitirira pakati pakufa pamwamba, ndipo kugwirizanako kwawonongeka ndikusweka;

②Kulumikizana kwa gawo lotsekera sikuli kolimba, ndipo kumakhala kotayirira ndikugwa;

③ Zida za cholumikizira sizolondola, ndipo sizingathe kupirira kuwonongeka kwa sing'anga ndi kuvala kwamakina.

Njira yosamalira:

① Kugwira ntchito moyenera, kutseka valavu sikungagwiritse ntchito mphamvu zambiri, kutsegula valavu sikungathe kupitirira pakati pakufa pamwamba, valavu itatsegulidwa kwathunthu, gudumu lamanja liyenera kusinthidwa pang'ono;

②Kulumikizana pakati pa gawo lotsekera ndi tsinde la valavu kuyenera kukhala kolimba, ndipo payenera kukhala choyimitsa kumbuyo pakulumikiza kwa ulusi;

③ Zomangira zomwe zimagwiritsidwa ntchito polumikiza gawo lotseka ndi tsinde la valve liyenera kupirira dzimbiri lapakati ndikukhala ndi mphamvu zamakina komanso kukana kuvala.
