Chinangwa chekushandisa cheki chevhavha ndechekudzivirira kudzokera shure kwepakati. Kazhinji, cheki valve inofanira kuiswa panzvimbo yekubuda kwepombi. Pamusoro pe,cheki valve inofanirawo kuiswa panzvimbo yekubuda kwe compressor. Muchidimbu, kuitira kudzivirira kudzoka shure kwepakati, cheki chevhavha inofanira kuiswa pamichina, chigadziro kana pombi.Kazhinji, vertical lift check valve inoshandiswa pahorizontal pipeline ine zita re 50mm. Yakatwasuka-kuburikidza nekusimudza cheki mavharuvhu anogona kuiswa pamapaipi ese akachinjika uye akatwasuka. Ivhavha yepasi inowanzoiswa chete papombi yakatwasuka painopinza pombi, uye yepakati inoyerera kubva pasi ichienda kumusoro. Iyo swing cheki yevhavha inogona kuitwa yakakwira zvakanyanya kushanda, PN inogona kusvika 42MPa, uye iyo DN inogonawo kuva yakakura kwazvo, kusvika ku2000mm kana kupfuura. Zvichienderana nemidziyo yegoko uye chisimbiso, inogona kushandiswa kune chero yekushanda svikiro uye chero yekushanda tembiricha renji. Iyo yepakati imvura, chiutsi, gasi, corrosive medium, mafuta, chikafu, mushonga, etc. Yepakati tembiricha yekushanda iri pakati -196~800℃. Nzvimbo yekuisa ye swing check valve haina kudziviswa. Iyo inowanzoiswa pahorizontal pombi, asi inogona zvakare kuiswa pane yakatwasuka pombi kana pombi yakarerekera.
Zviitiko zvinoshanda zvebutterfly cheki vharafudzakaderera-kudzvanywa uye yakakura-dhayamita, uye nguva yekuisa ishoma. Nokuti kushandiswa kwekushanda kwevhavhavhavha yevhavhavha haigoni kuva yakakwirira kwazvo, asi dhayamita yezita inogona kuva yakakura kwazvo, iyo inogona kusvika kupfuura 2000mm, asi iyo inonzi inonzi pressure iri pasi pe6.4MPa. Ivharuvhu yekuongorora butterfly inogona kugadzirwa kuva rudzi rwekusungirira, iyo inowanzoiswa pakati pemaflange maviri epombi, uchishandisa fomu yekubatanidza clamp. Nzvimbo yekuisa yevhavhavha yekuongorora butterfly haibvumirwi. Inogona kuiswa pahorizontal pombi, kana papombi yakatwasuka kana pombi yakarerekera.
Iyo diaphragm cheki vharafu inokodzera mapaipi anowanzo kuita sando yemvura. Iyo diaphragm inogona kunyatsobvisa nyundo yemvura inokonzerwa nekudzokera shure kwepakati. Nekuti tembiricha yekushanda uye kushandiswa kwekumanikidza kweiyo diaphragm cheki vharafu inoganhurirwa neiyo diaphragm zvinhu, inowanzo shandiswa mukudzika-kudzvanya uye kujaira tembiricha mapaipi, kunyanya akakodzera pombi yemvura pombi. Iyo yakawanda yepakati yekushanda tembiricha iri pakati -20 ~ 120 ℃, uye kushanda nesimba kuri <1.6MPa, asi diaphragm cheki vharafu inogona kuitwa yakakura dhayamita, uye iyo yakanyanya DN inogona kusvika kupfuura 2000mm. Diaphragm cheki mavharuvhu ane mvura yakanakisa. nyundo kuramba, chimiro chakareruka uye mutengo wakaderera wekugadzira, saka iwo akashandiswa zvakanyanya mumakore achangopfuura.
Kubva chisimbiso cheball check valve ibhora rakaputirwa nerabha, ine kuita kwakanaka kwekuisa chisimbiso, kushanda kwakavimbika uye kunaka kwesando yemvura kuramba; uye sezvo chisimbiso chinogona kuva bhora rimwe chete kana mabhora akawanda, inogona kuitwa muhupamhi hukuru. Zvisinei, chisimbiso chayo igomba rakaputirwa nerabha, iyo isingakodzeri mapaipi epamusoro-soro, asi chete kune mapiipi epakati uye epasi-pasi-pasi. hollow sphere yechisimbiso inogona kuputirwa ne polytetrafluoroethylene engineering mapurasitiki, inogona zvakare kushandiswa mumapaipi ane general corrosive media. Kupisa kwekushanda kwemhando iyi yevhavhavha yecheki iri pakati -101 ~ 150 ℃, iyo inonzi inodzvinyirira ndeye ≤4.0MPa, uye iyo inonzi dhayamita yakasiyana-siyana iri pakati pe200 ~ 1200mm.
