Momwe mungathanirane ndi kutayikira kwa valve, zifukwa zisanu ndi njira zomwe zingakuthandizeni kuthana ndi kutayikira kwa valve

Kutaya kwa valve ndi chinthu chokhumudwitsa kwambiri kwa kasitomala aliyense. Kutayikira kukachitika, nthawi zambiri zimapangitsa kuti ntchitoyi isachitike bwino m'tsogolomu. Ndikofunikira kuthetsa nthawi yomweyo. LIKE VALVE imapanga zifukwa zisanu ndi njira zokuthandizani kuthana ndi kutayikira kwa VALVE!

Kutaya kwa bolodi loyendetsa mafuta ndi valavu imodzi yoyenda

Chifukwa:

1, kuponyera chitsulo kuponyera khalidwe si mkulu, bolodi mafuta dera ndi limodzi otaya valavu thupi pamwamba dzenje mchenga, limagwirira lotayirira, kuwotcherera chotupa ndi zofooka zina;

2, ozizira yosungirako mng'alu;

3, kuwotcherera si zabwino, pali kuwotcherera zotupa, kuwotcherera, mkati nkhawa ming'alu ndi zofooka zina;

4. Vavu yachitsulo ya nkhumba imawonongeka ikagundana ndi zinthu zolendewera.

Njira zosamalira:

1. Kupititsa patsogolo kuponyera khalidwe, kuchita compressive mphamvu mayeso mosamalitsa malinga ndi makonzedwe pamaso unsembe;

2, kutentha mu 0 ℃ ndi 0 ℃ mkati valavu, ayenera kuchita kutchinjiriza kutentha kapena kutentha, valavu ayenera kuchotsedwa yosungirako madzi;

3. Kuwotcherera kwa mbale yamafuta ozungulira ndi valavu imodzi yoyenda pamodzi ndi kuwotcherera kwamagetsi kuyenera kuchitidwa motsatira malamulo oyendetsera chitetezo chamagetsi, komanso kuzindikira kolakwika ndi kuyesa kwamphamvu kwamphamvu kuyeneranso kuchitidwa pambuyo kuwotcherera; Nthambi mbalame chikhalidwe maphunziro HVAC kapangidwe Mphunzitsi Du

4. Ndizoletsedwa kukankhira ndi kuyika zinthu zopachika pa valve, ndipo siziloledwa kugunda chitsulo cha nkhumba ndi ma valve opanda zitsulo ndi nyundo. Kuyika ma valve akulu akulu ayenera kukhala ndi chimango chothandizira.

Awiri, kutayikira kwa kulongedza katundu

Kuwonekera kwa valavu, gawo la zodzaza ndi lalikulu.

Chifukwa:

1, chodzazacho sichimagwiritsidwa ntchito moyenera, chosagonjetsedwa ndi kukokoloka kwa zinthu, chosagonjetsedwa ndi kuthamanga kwa valve kapena pampu ya vacuum, kutentha kwakukulu kapena kutentha kwambiri;

2, kulongedza unsembe si zolondola, pali ang'onoang'ono m'malo lalikulu, wononga zokhotakhota kugwirizana mutu si zabwino, lotayirira pansi kumangitsa ndi zolakwa zina;

3, filler kupitirira moyo utumiki, wakhala kukalamba, kusowa ductility;

4, valavu tsinde mwatsatanetsatane si mkulu, kupinda, kukokoloka, kuwonongeka ndi zolakwa zina;

5, kuchuluka kwa mphete zonyamula sikokwanira, gland siyimangika;

6, gland, ma bolts a nangula, ndi zigawo zina zimawonongeka, kotero kuti gland silingatseke;

7, ntchito yeniyeniyo ndiyopanda nzeru, mphamvu zambiri, etc.;

8, kupendekeka kwa gland, kusiyana pakati pa gland ndi tsinde kumakhala kochepa kwambiri kapena kwakukulu kwambiri, zomwe zimapangitsa kuwonongeka kwa tsinde, kuwonongeka kwa katundu.

Njira zosamalira:

1. Zida zopangira ndi mawonekedwe a zodzaza ziyenera kugwiritsidwa ntchito molingana ndi momwe amagwirira ntchito;

2, molingana ndi zofunikira za chojambulira choyenera, disk iyenera kuyikidwa mozungulira ndi kuzungulira, kulumikiza mutu kuyenera kukhala 30 ℃ kapena 45 ℃;

3, moyo wautumiki ndi wautali kwambiri, ukalamba, zolongedza zowonongeka ziyenera kuchotsedwa nthawi yomweyo;

4, valavu tsinde kupinda, kuwonongeka kuyenera kuwongoleredwa, kukonza, kuwonongeka kwakukulu kuyenera kuchotsedwa nthawi yomweyo;

5, kulongedza kumayenera kukhazikitsidwa molingana ndi kuchuluka komwe kwatchulidwako, gland iyenera kukhala yofanana komanso yolimba, mawotchi othamanga ayenera kukhala ndi kusiyana kopitilira 5mm;

6, gland yowonongeka, mabawuti a nangula ndi zigawo zina, ziyenera kukonzedwa kapena kuchotsedwa nthawi yomweyo;

7, ayenera kutsatira malamulo chitetezo ntchito, kupatula kugunda mtundu spindle, ndi liwiro yachibadwa ntchito yeniyeni mphamvu;

8, ayenera symmetrical ndi symmetrical kumangitsa gland nangula bawuti, gland ndi tsinde kusiyana ndi laling'ono kwambiri, mmene ndingathere kuwonjezera kusiyana; Chilolezo cha gland ndi tsinde ndi chachikulu kwambiri, chiyenera kuchotsedwa.

Chachitatu, kutayikira kowonekera

Chifukwa:

1, pamwamba akupera osagwirizana, sangakhoze kutulutsa pafupi mzere;

2, tsinde la valavu ndi mbali zapafupi za malo olumikizirana atapachikidwa mumlengalenga, zopindika kapena zowonongeka;

3, tsinde la valavu akupindika kapena unsembe skew, kuti chatsekedwa mbali mapendekero kapena kukumana pakati;

4, khalidwe lapamwamba lapamwamba ndilopanda nzeru kapena ayi malinga ndi momwe ntchito ya valve ikuyendera.

Njira zosamalira:

1, malinga ndi momwe amagwirira ntchito mulingo woyenera wa zida zaku Britain za gasket ndi mawonekedwe;

2, kusintha mosamala, khola kwenikweni ntchito;

3, zomangira nangula ziyenera kukhala zofananira komanso zofananira, ndipo chowongolera cha torque chiyenera kugwiritsidwa ntchito pakafunika kutero. Mphamvu yodzitetezera iyenera kukwaniritsa zofunikira, osati zazikulu kapena zazing'ono. Kulumikizana kwa flange ndi flange kuyenera kukhala ndi kusiyana kwa torque;

4, unsembe wa gasket ayenera kukumana mayikidwe pakati, kunyamula mphamvu symmetrical, gaskets saloledwa rebar chilolo ndi ntchito gaskets awiri;

5, malo amodzi otuluka kukokoloka padziko, kupanga kuwonongeka ndi processing, processing khalidwe si mkulu, ayenera kuchita yokonza, akupera, mtundu anayendera, kupanga malo amodzi chotulukira pamwamba mogwirizana ndi zofunika zofunika;

6, poika makina ochapira, tcherani khutu kuyeretsa, kugwiritsa ntchito mafuta kuti muchotse pamwamba, ndipo chochapira sichingagwe.

Chachinayi, kutayikira kwa mgwirizano wa mphete yosindikiza

Chifukwa:

1. Mphete yosindikizayo siyimakanizidwa mwamphamvu;

2, mphete yosindikiza ndi kuwotcherera yokha, kutsitsi kuwotcherera khalidwe ndi osauka;

3, kusindikiza mphete kugwirizana ulusi kunja, wononga, kuthamanga mphete lotayirira;

4. Mphete yosindikiza imalumikizidwa ndikuwonongeka.

Njira zosamalira:

1, chosindikizira chiyenera kubayidwa mu kutayikira kwa kugubuduza kusindikiza kenako ndikugudubuza kokhazikika;

2. Mphete yosindikizayo idzawotchedwanso molingana ndi muyezo wowotcherera. Utsi kuwotcherera sangathe kukonzedwa kwa kuwotcherera choyambirira kutsitsi ndi processing kupanga;

3. Chotsani zitsulo, yeretsani mphete yokakamiza, chotsani ndikusintha zigawo zowonongeka, perani malo osindikizira ndi mpando wogwirizanitsa, ndikugwirizanitsa. The zigawo zikuluzikulu ndi kuwonongeka kukokoloka kwakukulu akhoza kukonzedwa ndi kuwotcherera kapena kugwirizana.

4, kusindikiza mphete kugwirizana pamwamba ndi dzimbiri, akhoza kukonzedwa ndi akupera, kugwirizana ndi njira zina, sangathe kukonza ayenera kuchotsedwa pamene mphete yosindikiza.

Chachisanu, zimitsani chidutswacho chidagwa kuti chiwononge

Chifukwa:

1, ntchito yeniyeniyo si yabwino, kotero kuti mbali zotsekedwa zimakakamira kapena kupitirira malo okwera akufa, kugwirizanako kumawonongeka ndi kusweka;

2, kuzimitsa kugwirizana si olimba, lotayirira ndi kugwa;

3, kugwirizana zakuthupi si zolondola, sangathe kupirira dzimbiri zinthu ndi makina kuwonongeka zida.

Njira zosamalira:

1, ntchito yoyenera yogwira ntchito, kutseka valavu sikungakhale yamphamvu kwambiri, kutsegula valavu sikungakhale pamwamba kuposa pamwamba pakufa, valve itatha kutsegulidwa, spindle iyenera kutembenuza pang'ono;

2. Kugwirizana pakati pa gawo lotseka ndi tsinde la valve liyenera kukhala lolimba, ndipo kugwirizana kwa flange kuyenera kukhala ndi gawo lobwerera;

3, magawo omwe amalumikizidwa ndi tsinde la valve ayenera kupirira kukokoloka kwa zinthuzo, komanso kukhala ndi mphamvu zinazake komanso kukana kuvala.
