Kufotokozera Kwachidule:

3 njira plug valvendi chidutswa chotseka kapena valavu yozungulira yozungulira, pozungulira madigiri 90 kuti apange doko pa pulagi ya valve ndi thupi la valve lomwelo kapena losiyana, lotseguka kapena lotseka valavu.Pulagi ya pulagi valavu akhoza kukhala cylindrical kapena conical mu mawonekedwe.M'mapulagi a cylindrical, mayendedwe amakhala amakona anayi;Mu pulagi ya tapered, njirayo ndi trapezoidal.Maonekedwe awa amapangitsa kapangidwe ka valavu ya pulagi kukhala yopepuka, koma nthawi yomweyo imapanga kutayika kwina.Valavu ya pulagi ndiyoyenera kwambiri kudula ndi kulumikiza sing'anga ndi kusokoneza, koma kutengera mtundu wa ntchito komanso kukana kukokoloka kwa malo osindikizira, nthawi zina imatha kugwiritsidwanso ntchito popumira.Chifukwa kuyenda pakati pa kusindikiza pamwamba pa valavu ya pulagi kumakhala ndi zotsatira zopukuta, ndipo pamene kutsegulidwa kwathunthu, kumatha kulepheretsa kukhudzana ndi sing'anga yothamanga, kotero kungagwiritsidwe ntchito pakatikati ndi particles zoimitsidwa.Chinthu china chofunika kwambiri cha valavu ya pulagi ndi kumasuka kwake kuti agwirizane ndi mapangidwe a njira zambiri, kotero kuti valve ikhoza kukhala ndi njira ziwiri, zitatu, kapena zinayi zosiyana.Izi zimathandizira kamangidwe ka mapaipi, kuchepetsa kugwiritsa ntchito ma valve, komanso kuchepetsa kuchuluka kwa zolumikizira zofunika pazida.
