Valve yowunikira ndi valve yomwe zigawo zake zotsegula ndi zotseka ndi ma discs, omwe chifukwa cha misa yawo komanso kuthamanga kwa ntchito kumalepheretsa sing'anga kubwerera. Ndi valve yodziwikiratu, yomwe imatchedwanso valavu yodzipatula, valve yobwerera, valavu imodzi, kapena valavu yoyendera. Mtundu wa Nyamulani ndi mtundu wa swing ndi magulu awiri omwe diski imatha kuyenda.

Tsinde la valve lomwe limathandizira diski mu valavu yapadziko lonse lapansi ndi kukwezachekeni valavukugawana mamangidwe ofanana. Sing'anga imalowa m'mbali yakumunsi ndikutuluka kudzera kumtunda wakumtunda (mbali yakumtunda). Valavu imatsegula pamene kulowetsedwa kwa inlet kumadutsa chiwerengero cha kulemera kwa disc ndi kukana kwake. Valavu imatsekedwa pamene sing'anga ikuyenda molunjika.

Ntchito ya valavu yokweza ndi yofanana ndi ya valavu ya swing check valve yomwe imaphatikizapo mbale zozungulira. Pofuna kuti madzi asamayende chammbuyo, ma valve owunika amagwiritsidwa ntchito ngati ma valve pansi pazida zopopera. Ntchito yodzipatula yachitetezo imatha kuchitidwa kudzera pa cheke valavu ndi kuphatikiza valavu ya globe. Kukaniza mopitirira muyeso ndi kusindikiza kosakwanira pamene kutsekedwa ndizovuta.

M'mizere yotumizira machitidwe othandizira komwe kupanikizika kumakwera pamwamba pa kukakamiza kwa dongosolo,fufuzani ma valveamalembedwanso ntchito. Ma valve cheke ndi ma valve okweza ndi mitundu iwiri yayikulu ya ma cheke. Mavavu a swing cheki amazungulira ndi pakati pa mphamvu yokoka (akuyenda motsatira axis).

Ntchito ya valavu iyi ndikuletsa kuyenda kwa sing'anga kupita kunjira imodzi ndikutsekereza kuyenda kwina. Vavu iyi nthawi zambiri imagwira ntchito yokha. Disiki ya valve imatsegula pamene kuthamanga kwamadzimadzi kukuyenda njira imodzi; pamene kuthamanga kwamadzimadzi kukuyenda kumbali ina, mpando wa valve umakhudzidwa ndi kuthamanga kwa madzi ndi kulemera kwa diski ya valve, yomwe imalepheretsa kutuluka.

Gulu ili la ma valve limaphatikizapo ma check valves, monga swing check valves ndi liftfufuzani ma valve. Disiki yooneka ngati chitseko ya valavu ya swing check valve imatsamira momasuka pampando wotsetsereka chifukwa cha makina a hinge. Valve clack imapangidwa mu hinge mechanism kuti ikhale ndi malo okwanira osambira ndipo imatha kulumikizana kwathunthu ndi mpando wa valve clack kuti itsimikizire kuti imatha kufika pamalo oyenera pampando.

Kutengera ndi magwiridwe antchito, ma disks amatha kupangidwa kwathunthu ndi chitsulo kapena kukhala ndi zikopa, mphira, kapena zokutira pazitsulo. Kuthamanga kwamadzimadzi kumakhala kosalephereka konse pamene swing check valve yatsegulidwa kwathunthu, motero kutaya kwa mphamvu kudzera mu valve kumakhala kochepa.

Pamalo osindikizira a mpando wa valve pa thupi la valavu ndi pamene pali disk check valve disc. Zotsalira za valve ndizofanana ndi valavu ya globe, kupatulapo kuti diski ikhoza kuwuka ndikugwa momasuka. Pamene pali backflow wa sing'anga, valavu chimbale amagwera mmbuyo ku mpando valavu, kudula otaya. Kuthamanga kwamadzimadzi kumakweza diski ya valve kuchoka pamalo osindikizira a mpando wa valve. Chimbalecho chikhoza kupangidwa ndi chitsulo chonse, kapena chikhoza kukhala ndi mphete za mphira kapena mapepala oikidwa mu disk frame, malingana ndi momwe amagwiritsira ntchito.

Valve yowunikira ili ndi njira yocheperako kuposa valavu yosinthira, zomwe zimapangitsa kuti pakhale kutsika kwakukulu kudzera pa valavu yowunikira komanso kutsika kwamadzi othamanga.
