Mfundo Zofunika Kwambiri Zokhudza Kukhazikitsa Ma Valve a Pipeline

I. Kukonzekera kusanayambe

1. Yang'anani chitsanzo cha valavu, mulingo wa kupanikizika, ndi chizindikiritso cha njira yoyendera kuti muwonetsetse kuti ikukwaniritsa zofunikira pa kapangidwe kake.

2. Yang'anani kuyera kwa valavu yophimba thupi ndikuchotsa zinthu zoteteza phukusi ndi zinthu zina zakunja.

3. Ma valve olumikizira matako ayenera kukonzedwa kale okhala ndi mipata, ndipo ma valve olumikizira flange ayenera kuyang'ana kukhulupirika kwa pamwamba potseka.

II. Kuwongolera Malangizo Okhazikitsa

1. Valavu ya dziko lapansi ndivalavu yoyezera kukweza yoyimiriraiyenera kuyikidwa molunjika motsatira njira yomwe yasonyezedwa ndi muvi womwe uli pa thupi la valavu.

2. Mwachidule,valavu yoyambira yosakwera, vavu ya gulugufe yamtundu wa madzi, ndi ma valve a mpira akhoza kuyikidwa mbali zonse ziwiri, koma chisamaliro chiyenera kuperekedwa kuti ntchito ikhale yosavuta.

3. Ma valve amagetsi / opumira mpweya ayenera kusunga malo oti agwiritsidwe ntchito ndi kukonzedwa kwa actuator.

III. Mafotokozedwe a Kukhazikitsa Zowotcherera

1. Valavu yolumikizira matako iyenera kusungidwa pakati panthawi yolumikiza kuti isatseguke chifukwa cha kusintha kwa kutentha.

2. Gwiritsani ntchito chowotcherera cha argon arc kuti mupange maziko, ndikuwongolera kutentha kwa interlayer kuti kusapitirire kutentha komwe kwayesedwa kwa valavu.

3. Pambuyo powotcherera, valavu iyenera kuyesedwa bwino kuti itsimikizire kuti imatseguka ndi kutseka bwino.

IV. Mfundo Zofunika Kwambiri Zolumikizira Flange

1. Malo otsekera flange amakhalabe ofanana, ndipo kupotoka kwakukulu komwe kungaloledwe sikupitirira 0.15% ya mainchesi akunja a flange.

2. Gasket iyenera kuyikidwa pakati, mabotolo ayenera kumangidwa mofanana komanso mofanana, ndipo mphamvu yovomerezeka iyenera kufikidwa katatu.

3. Mabotolo olumikizira ma valve otentha kwambiri ayenera kumangidwa kawiri kutentha kukatentha.

V. Kulamulira Ubwino

1. Kuyesa mphamvu ndi kutseka ndikofunikira mukakhazikitsa.

2. Mukatsuka makina, valavu yowongolera, mita yoyezera madzi ndi zida zina ziyenera kudyedwa.

3. Lembani zolemba zoyikira, kuphatikizapo deta yofunika monga nambala ya malo a valavu, kuthamanga kwa mayeso, mphamvu yogwirira ntchito, ndi zina zotero.

Dziwani: Vavulopu siyenera kugwiritsidwa ntchito ngati malo othandizira payipi. Mavavu akuluakulu amafunika chimango chothandizira chosiyana. Pambuyo poyika, vavulopuyo iyenera kukhala yotsekedwa bwino komanso yotetezedwa kuti isawonongeke ndi ntchito zina.
