Valavu yolumikizira kwambiri yokhala ndi chitsulo chosadzolaMAVALU OKWERA PLUGAdapangidwa zaka zoposa 80 zapitazo kuti athetse mavuto omwe analipo ndi ma valve omwe alipo kale mu ntchito yokonza ma catalyst. Popeza ma valve anali atayamba bwino kwambiri mu ntchito iyi, adalimbikitsidwanso kuti agwiritsidwe ntchito mu ntchito zina za hash mumakampani opanga mankhwala ndi petrochemical.

MFUNDO YOTSEGULA NDI KUTSEKA VALVU YOTSEGULA YA PLIKI YOFUNIKA KWAMBIRIValavu ya pulagi yokwezera

Kutsegula kwa valavu:

• 1) tembenuzani gudumu lamanja kuti pulagi ikwezedwe ndikulekanitsidwa ndi pamwamba potseka;
• 2) Kenako tembenuzani chogwirira ndi madigiri 90 kuti mulumikize njira ya pulagi ku njira ya thupi la valavu, kuti valavu ya pulagi itsegulidwe.

Pakutsegula ndi kutseka valavu, pulagi imakwezedwa ndikulekanitsidwa ndi mpando wa valavu, kotero mphamvu yogwirira ntchito ndi yaying'ono kwambiri, yosavuta kutsegula ndi kutseka valavu. Ndipo pamwamba pake potseka valavuyo pamakhala polephera kukanda panthawi yotsegula kapena kutseka. Choncho valavuyo imakhala ndi moyo wautali.
