MFUNDO YOTSEKULIRA NDI KUtseka KWAvalavu yokweza pulagi

Kutseka kwa valve:

• 1) tembenuzirani chogwiriracho ndi digiri ya 90 kuti njira ya pulagi ikhale yowongoka kunjira ya valavu
• 2) kenaka tembenuzani gudumu lamanja kuti mutsike pulagi, kuti valavu itsekeke.

Pakutsegula ndi kutseka kwa valve, pulagi imakwezedwa ndikulekanitsidwa ndi mpando wa valve, kotero kuti torque yogwiritsira ntchito ndi yaying'ono kwambiri, yosavuta kutsegula ndi kutseka valve.Ndipo malo osindikizira ndi umboni wokandwa panthawi yotsegula kapena kutseka.Choncho valavu imakhala ndi moyo wautali.The handwheel chogwirizira kukweza mtundu pulagi valavu ali ndi kapangidwe yaying'ono, voliyumu yaing'ono ndi kukana madzimadzi otsika.
