Chenjezo Pakuyika Mavavu a Gulugufe

Chenjezo Pakuyika Mavavu a Gulugufe

1. Wonjezerani flange ku chitoliro ndi kuziziritsa kutentha kozungulira musanakweze valavu ku flange.Apo ayi, kutentha kwakukulu kopangidwa ndi kuwotcherera kudzakhudza ntchito ya mpando wofewa.
2. Mphepete mwa ma flanges otsekemera ayenera kutsekedwa kuti asawonongeke kuti pasakhale kuwonongeka kwa mpando wofewa panthawi ya kuika valavu. Pamwamba pa flange iyenera kukhala yopanda kuwonongeka ndi kusinthika, kuchotsa dothi lonse, fumbi ndi zinthu zakunja, ndikupewa kutuluka kwa madzi a valve ndi mawonekedwe a flange.
3. Tsukani flange ndi mkati mwa payipi kuti muchotse sputter, sikelo ndi matupi ena akunja osiyidwa ndi kuwotcherera.

4. Poika mapaipi pakati pa ma valve, kulondola kolondola kwapakati pa mizere ya pamwamba ndi yapansi ya madzi ndikofunika kuti pakhale ntchito yopanda mavuto.Nthawi yosadziwika bwino yomwe ikuwonetsedwa mu Chithunzi 1 iyenera kupeŵedwa.
5. Mukayika valavu, konzani ma bolts pansi pa chitoliro pamtunda womwewo kuti mugwire ntchito yothandizira, ndikusintha mtunda pakati pa ma flanges mpaka mbali ziwiri za thupi la valve zili pafupi 6-10 mm. Kumbukirani kuti valavu imatha kutsegulidwa kuchokera pamalo otsekedwa kupita ku 10 °.

6. Lowetsani ma bolts awiri mu kalozera wapansi wa valavu ndikuyika mosamala kuti flange pamwamba isawononge mpando wofewa.6.(onani chithunzi 2)
7. Kenaka ikani mabawuti ena awiri mu ndodo yolondolera pamwamba pa valavu, kuonetsetsa malo olondola apakati pakati pa chitoliro ndi valavu.
8. Tsegulani valavu katatu kuti muwone ngati kukhudzana pakati pa mbale ya valve ndi flange sikuli bwino.
9. Chotsani mabawuti oyika ndikuyika mabawuti onse mozungulira thupi mosinthana kumangirira kwa diagonal (onani Mkuyu 3 ndi 4) mpaka flange ikhudza thupi.
10. Perekani chithandizo cha valve mukamayika actuator kuti mupewe kupindika kwa khosi la valve ndikuchepetsa kukangana pakati pa valavu ndi chitoliro.
11. Osaponda pakhosi la valve kapena gudumu lamanja la valve.
12. Osayika DN350 kapena ma valve akuluakulu mozondoka.
13. Osayika ma valve a butterfly pa ma valve kapena mapampu chifukwa izi zitha kuwononga mukakhudza mbale.
14. Osayika ma valve kumunsi kwa ma elbows ndi tapering tubing, kapena kuwongolera ma valve pamene mitengo yothamanga ikusintha. Pankhaniyi, tikulimbikitsidwa kuyika valavu pamtunda wa pafupifupi 10 kuchulukitsa kwadzina kwa valve.
15. Kuyika valavu kuyenera kuganizira kuti ndi chimbale chiti chomwe chidzakumana ndi kuthamanga ndi kupanikizika panthawi yotumiza madzi.
