Cheki vharuvhu imhando yevharuvhu inovhurika nekuvhara yega nesimba repakati pachayo. Cheki mavharuvhu anonyanya kushandiswa kudzivirira backflow ye media. Kana imwe nguva mvura ichiyerera kumashure, cheki valve inovhara. Cheki mavharuvhu anowanzo kukamurwa kuita yekusimudza cheki mavharuvhu uye swing cheki mavharuvhu.
Lift Check Valve (Globe Check Valve): Iyo dhisiki yekusimudza Tarisa Valve kazhinji inofamba ichitevedza yakatwasuka yepakati mutsara wecheki valve body. Kusimudza cheki mavharuvhu anogona kukamurwa kuva horizontal uye vertical modhi. Iyo yekusimudza cheki valve inoumbwa nemuviri, bhoneti, dzinde, chigaro uye spool.
Swing cheki vharafu (pivotal cheki vharafu): Iyo disc ye swing cheki vharafu inowanzotenderedza pini kunze kwechigaro. Swing cheki vharafu inogona kukamurwa kuva mhando nhatu: imwe vharafu, kaviri vharafu uye vharafu yakawanda. Iyo pivotal cheki valve inoumbwa nemuviri, chivharo, shaft inotenderera uye ndiro inoputika.
Iyo cheki valve inoshanda zvinoenderana nekumanikidza shanduko ye raccoon fluid pachayo, uye inodzivirira midhiya kubva kumashure. Inonyanya kushandiswa mumapaipi ekupa mvura.
Ivhavha yekukwevera pasi imhando yevharuvhu yekutarisa. Kusimudza suction yezasi vharafu ine yakanaka yekuisa chisimbiso kuita uye yakaderera ruzha. Inowanzo shandiswa mumapaipi akachinjika ane dhayamita yezita isingasviki 200 mm. Swing suction pasi mavharuvhu anowanzo shandiswa mumapaipi akasimukira kana makuru edhayamita nekuda kwekusina kuvharika kwawo uye ruzha rwakanyanya. Ivhavha yepasi yekusveta inoiswa pamagumo epombi yekusveta yepombi, uye yakabatana nepombi nembabvu dzemukati kana flanges.
