Rudzi rwekusimudza rune kuita kurinani kwekuisa chisimbiso pane iyo inoswing mhando, uye ine yakakura kupikisa mvura.Rudzi rwakachinjika runofanira kuiswa mupombi yakachinjika, uye mhando yakatwasuka inofanira kuiswa mupombi yakatwasuka.
Kuisa nzvimbo ye swing check valve haina kukwana.Inogona kuiswa muhorizontal, vertical kana inclined pipelines.Kana yakaiswa mumapaipi akatwasuka, kuyerera kwepakati kunofanirwa kubva pasi kuenda kumusoro.
Swing cheki mavharuvhuhaifanirwe kugadzirwa kuita mavharuvhu madiki, uye anogona kugadzirwa musimba rekushanda.Kumanikidzwa kwezita kunogona kusvika 42 MPa, uye dhayamita yezita inogonawo kuva yakakura, kusvika 2000 mm.Inogona kuiswa kune chero yekushanda svikiro uye chero yekushanda tembiricha renji zvinoenderana nezvinhu zvegoko uye chisimbiso.Pakati imvura, chiutsi, gasi, corrosive medium, oiri, mushonga, etc. Kushanda tembiricha yepakati ndeye - 196 - 800 C.
Swing check valve inokodzera kuderera kwepasi uye caliber yakakura, uye kuiswa kwayo kunogumira.
Nzvimbo yekuisa yewafer cheki valve haina kuganhurirwa.Inogona kuiswa muhorizontal pipeline kana mu vertical or inclined pipeline.
Bhora cheki mavharuvhuakakodzera epakati uye akaderera kumanikidza mapaipi uye anogona kugadzirwa muhombe caliber.
Iyo shell zvinhu zvevhavha yekutarisa bhora inogona kugadzirwa nesimbi isina tsvina, uye gomo sphere yechisimbiso inogona kuputirwa muPTFE engineering mapurasitiki.Naizvozvo, inogona zvakare kushandiswa mumapaipi eiyo general corrosive media.Tembiricha yekushanda iri pakati - 101 - 150 C, iyo yekumanikidza yezita isingasviki 4.0 MPa, uye yezita rekupfuura renji iri pakati peDN200 - DN1200.
Tarisa mavharuvhuinofanira kuenzaniswa.Vatengesi vemavharuvhu vanofanirwa kupa data pamasaizi akasarudzwa kuitira kuti vawane hukuru hwemavharuvhu paanenge akazaruka pachiyero chakapihwa chekuyerera.
