2. Ikani valavu yokhala ndi nyumba ya kasupe m'mwamba kuti mupewe kupsinjika kwa kutentha ndi mphamvu.
3. Onetsetsani kuti valavu imatetezedwa kuzinthu zodutsa ngati nyundo yamadzimadzi mu dongosolo.
4. Valavu iyenera kuyikidwa ndikuyenda kupita ku valve cone monga momwe muvi wa valve ukuwonekera.

Kuwotcherera

1. Chotsani pamwamba musanayambe kuwotcherera kuti muteteze kuwonongeka kwa O-mphete ndi ma teflon gaskets.
2. Gwiritsani ntchito zida ndi njira zowotcherera zomwe zimagwirizana ndi zida zanyumba.
3. Chotsani mkati kuti muchotse zinyalala zowotcherera musanayambe kukonzanso.
4. Tetezani valavu ku dothi ndi zinyalala panthawi yowotcherera.

Msonkhano

1. Chotsani zinyalala zowotcherera ndi dothi pamapaipi ndi ma valve musanayambe kusonkhanitsa.
2. Limbani pamwamba ndi torque wrench ku mfundo zomwe zafotokozedwa.
3. Onetsetsani kuti mafuta pa mabawuti ali bwino musanalumikizanenso.

Mitundu ndi Chizindikiritso

• Chizindikiritso cholondola cha valavu chimapangidwa kudzera pa chizindikiro cha ID pamwamba ndi stampkukhala pa thupi la valve.
• Kupewa dzimbiri kunja pamwamba ndi oyenera ❖ kuyanika zoteteza pambuyo unsembe.

Kuyika

• Zindikirani! POV yamtundu wa vavu imayikidwa m'gulu la chowonjezera chodzaza ndi kompresa (osati ngati chowonjezera chachitetezo).
• Chifukwa chake, valavu yotetezera (mwachitsanzo SFV) iyenera kuikidwa kuti iteteze dongosolo kupsinjika kwambiri.

$Mafiriji

• Ziyenera kutsimikiziridwa kuti valavu imatetezedwa ku zovuta zowonongeka monga "nyundo yamadzi" mu dongosolo.

Mayendedwe akulimbikitsidwa

• Valavu iyenera kuyikidwa ndikuyenda kupita ku chulu cha valve monga momwe muvi wasonyezera pa chithunzicho. 2.
• Kuyenda mosiyana sikuvomerezeka.

Kuwotcherera

• Pamwamba payenera kuchotsedwa musanayambe kuwotcherera (mkuyu 3) kuteteza kuwonongeka kwa mphete za O pakati pa thupi la valve ndi pamwamba, komanso teflon gasket pampando wa valve.
• Osagwiritsa ntchito zida zothamanga kwambiri pakugwetsa ndi kulumikizanso.
• Onetsetsani kuti girisi pa mabawuti ali bwino musanalumikizanenso.
• Zida zokha ndi njira zowotcherera zomwe zimagwirizana ndi zida zanyumba za valve ziyenera kugwiritsidwa ntchito.
• Vavu iyenera kutsukidwa mkati kuti ichotse zinyalala zowotcherera zikamaliza kuwotcherera komanso valavu isanasonkhanitsidwe.
• Pewani kuwotcherera zinyalala ndi dothi mu ulusi wa nyumba ndi pamwamba.

Kuchotsa pamwamba kungasiyidwe malinga ngati:

• Kutentha m'dera pakati pa thupi la valve ndi pamwamba, komanso m'dera lapakati pa mpando ndi teflon cone panthawi yowotcherera, sikudutsa +150 ° C / + 302 ° F.
• Kutentha kumeneku kumadalira njira yowotcherera komanso kuziziritsa kulikonse kwa valavu panthawi yowotcherera yokha (kuzizira kumatha kutsimikiziridwa ndi, kwa ex.ample, kukulunga nsalu yonyowa kuzungulira thupi la valve).
• Onetsetsani kuti palibe dothi, zinyalala zowotcherera, ndi zina zotere, zomwe zimalowa mu valve panthawi yowotcherera.
• Samalani kuti musawononge mphete ya teflon cone.
• Nyumba ya valve iyenera kukhala yopanda kupsinjika (katundu wakunja) mutatha kukhazikitsa.

Msonkhano

• Chotsani zinyalala zowotcherera ndi zinyalala za mapaipi ndi ma valve musanayambe kusonkhanitsa.

Kumangitsa

• Limbani pamwamba ndi chowotcha cha torque ku mfundo zomwe zasonyezedwa patebulo (mku. 4).
• Osagwiritsa ntchito zida zothamanga kwambiri pakugwetsa ndi kulumikizanso. Onetsetsani kuti girisi pa mabawuti ali bwino musanalumikizanenso.

Mitundu ndi chizindikiritso

• Kuzindikiritsa kolondola kwa valavu kumapangidwa kudzera pa chizindikiro cha ID pamwamba, komanso ndi stampkukhala pa thupi la valve.
• Mbali yakunja ya nyumba ya valve iyenera kutetezedwa ku dzimbiri ndi zokutira zoyenera zotetezera pambuyo pa kukhazikitsa ndi kusonkhana.
• Chitetezo cha chizindikiro cha ID pojambula valavu ndikulimbikitsidwa.
• Ngati mukukayika, chonde lemberani Danfoss.
• Danfoss savomereza kuti ali ndi udindo pazolakwa ndi zosiyidwa. Danfoss Industrial
