1. Lub disc ntawm lubroj hmab lined check valveyog disk-puab thiab rotates nyob ib ncig ntawm lub rotating ncej ntawm lub valve rooj channel. Vim hais tias cov channel nyob rau hauv lub valve yog streamlined, cov ndlwg tsis kam yog me dua li ntawm npauj npaim hom kos valve. Npauj npaim kos valve tau muab faib ua ib hom disc, ob hom disc thiab ib nrab hom peb, peb cov ntaub ntawv no feem ntau muab faib raws li lub valve txoj kab uas hla, lub hom phiaj yog los tiv thaiv qhov nruab nrab ntawm kev txwv tsis pub ntws los yog rov qab, ua rau muaj kev cuam tshuam hydraulic.
2, Roj Hmab lined check valve: valve disc zawv zawg raws txoj kab ntsug ntsug ntawm lub valve lub cev kos valve, lub suab nrov kos valve tuaj yeem ntsia tau rau ntawm kab rov tav yeeb nkab, hauv qhov siab siab me me caliber check valve disc tuaj yeem siv pob. Lub cev lub cev ntawm lub kaw lus kaw lub cev yog tib yam li lub ntiaj teb valve (yuav ua tau universal nrog lub ntiaj teb valve), yog li nws cov dej tsis kam coefficient loj dua. Nws cov qauv zoo ib yam li lub ntiaj teb valve, thiab lub cev thiab disc yog tib yam li lub ntiaj teb valve. Lub sab sauv ntawm lub disc thiab sab qis ntawm lub valve npog yog ua tiav nrog lub tes tsho qhia, thiab daim ntawv qhia disc tuaj yeem nqa thiab txo qis hauv qhov kev qhia ntawm lub valve. Thaum qhov nruab nrab ntws, lub disc qhib los ntawm qhov nruab nrab thrust, thiab thaum nruab nrab tsis ntws, lub valve disc tsaws ntawm lub rooj zaum los ntawm txoj kab ntsug kom tiv thaiv qhov nruab nrab ntawm qhov tsis sib xws. Ncaj nraim-los ntawm npauj npaim kos valve nruab nrab inlet thiab qhov hluav taws xob channel kev taw qhia thiab lub rooj channel kev taw qhia perpendicular; Vertical nqa check valve, qhov nruab nrab inlet thiab qhov hluav taws xob channel kev taw qhia thiab lub rooj channel kev taw qhia yog tib yam, qhov ntws tsis kam yog me dua li ncaj nraim.
3. Roj Hmab lined check valve: lub valve disc swb raws txoj kab nruab nrab ntawm lub valve lub cev.Cov yeeb nkab hom kos valveyog lub valve tshiab, nws qhov me me, lub teeb yuag, kev ua haujlwm zoo, yog ib qho kev txhim kho ntawm kev kos valve. Tab sis cov kua cab coefficient yog me ntsis ntau dua li ntawm lub viav vias kos li qub.
