Vavu ya pulagi Yokhala Ndi Metal

Chiyambi cha Zamalonda

Vavu ya pulagi ndi mtundu wa valavu yomwe gawo lotseka - pulagi imazungulira madigiri 90 kuzungulira mzere wapakati wa thupi la valve kuti akwaniritse cholinga chotsegula ndi kutseka. Amagwiritsidwa ntchito podula, kugawa ndi kusintha njira yoyendetsera sing'anga paipi. Kutengera mtundu wa sing'anga ndi kukana kukokoloka kwa valavu / chitseko chosindikizira, nthawi zina chimatha kugwiritsidwa ntchito popumira. Chisindikizo chamafuta a Flange end plug ndi valve plug yopaka mafuta zikuwonetsedwa pachithunzichi. Pulagi valve ndi mtundu wofanana ndi ma valve a mpira, koma ndi malo osindikizira akuluakulu kuposa ma valve a mpira, kotero ndi ntchito yabwino yosindikizira, koma ndi torque yapamwamba, kotero ma valve amapulagi sakuperekedwa kwa mavavu aakulu kwambiri. Mosiyana ndi mavavu a mpira kapena ma valavu a pulagi osapaka mafuta, ma valve opaka mafuta amapangidwa ndi ma grooves mu pulagi omwe amasunga mafuta. Akagwiritsidwa ntchito, mafuta odzola amalepheretsa kumamatira ndipo amapereka mphamvu ya hydraulic yomwe imathandiza kukweza pulagi ndikuchepetsa mphamvu yofunikira pakugwira ntchito mozungulira. Kuonjezera apo, mafuta opangira mafutawa amapereka chisindikizo pakati pa malo okhala ndi ma valve ndi pulagi kuti kutsekeka kolimba kutheke. Pulagi mavavu chimagwiritsidwa ntchito mafuta ndi gasi mayendedwe, petrochemical, mankhwala, pharmacy, etc.
