Mutu 1 - Kodi Vavu Yoyang'ana Masika ndi Chiyani?
Valve yowunikira masika ndi valavu yomwe imatsimikizira kuyenda kwa njira imodzi ndikuletsa kubwereranso. Iwo ali ndi cholowera ndi chotulukira ndipo ayenera kuyikidwa mumayendedwe olondola kuti agwire bwino ntchito. Kumbali ya ma valve oyendera masika ndi ma valve onse owunika, pali muvi wolozera komwe kukuyenda. Valve yoyendera masika imatchedwa valavu imodzi kapena njira imodzi. Cholinga cha valve yoyang'ana kasupe ndikugwiritsa ntchito kasupe ndi kupanikizika komwe kumagwiritsidwa ntchito pa diski kuti asiye kubwerera kumbuyo kuti atseke valve.

Kuti valve yowunikira igwire bwino ntchito, iyenera kukhala ndi kusiyana kosiyana, kutuluka kuchokera ku kuthamanga kwambiri mpaka kutsika. Kuthamanga kwakukulu kapena kugwedezeka kumbali yolowera kumaloko kumapangitsa kuti madzi azidutsa mu valve ndikugonjetsa mphamvu ya kasupe mu valve.

Kawirikawiri, valavu yowunikira ndi chipangizo chomwe chimalola kuti mtundu uliwonse wa zofalitsa ziziyenda mbali imodzi. Mawonekedwe a cheke amatha kukhala ozungulira, disc, pistoni kapena poppet, mutu wa bowa. Ma valve oyendera masika amalepheretsa kuyenda mozungulira ngati njira yotetezera mapampu, zida ndi makina pamene kupanikizika mu dongosolo kumayamba kuchepa, pang'onopang'ono, kuyimitsa kapena kubwereranso.

Chaputala 2 - Kodi valavu yoyendera ndi chiyani?
Swing cheke mavavu amalola kuyenda kwa njira imodzi ndikudzitsekera zokha pamene kusweka kumachepetsa. Iwo ndi mawonekedwe a gulugufe valavu ndi chimbale kuphimba valavu kutsegula. Puck imamangiriridwa ku hinge kotero kuti ikakhudzidwa ndi kutuluka kwa media, puck imatha kutseguka kapena kutsekedwa. Muvi womwe uli kumbali ya thupi la valve umasonyeza komwe madzi amatuluka mkati ndi kunja kwa valve.

Kuthamanga kwamadzimadzi kumakankhira diski kapena chitseko kutseguka, kulola kuti madziwo adutse. Pamene kutuluka kukuyenda molakwika, chimbalecho chimatseka chifukwa cha kukankhira kwamadzimadzi kapena sing'anga.

Valavu yoyang'ana swing

Swing cheke mavavu safuna mphamvu zakunja. Kudutsa kwamadzi kapena media kudzera mwa iwo sikulepheretsedwa ndi kupezeka kwawo. Amayikidwa mopingasa m'mapaipi, koma akhoza kuikidwa molunjika malinga ngati kutuluka kukukwera.

Mutu 3 - Mitundu ya Mavavu a Spring Check
Kuti valve yodzaza masika igwire bwino ntchito, iyenera kukhala ndi kuthamanga kwamtunda, kotchedwa cracking pressure, kuti ikhale yotseguka. Kuchuluka kwa kusweka kofunikira kumatengera mtundu wa valavu, kapangidwe kake, mawonekedwe a kasupe ndi momwe amayendera mapaipi. Mafotokozedwe a kuthamanga kosweka ndi ma pounds per square inch (PSIG), pounds per square inch (PSI), kapena bar, ndipo metric unit of pressure ndi 14.5 psi.

Pamene kuthamanga kwa mtsinje kumakhala kotsika kusiyana ndi kuthamanga kwa phokoso, kupanikizika kwa msana kumakhala chinthu ndipo madzi amayesa kutuluka kuchokera kumtunda pa valve kupita kulowera. Izi zikachitika, valavu imatseka yokha ndipo kutuluka kumayima.

Spring Check Valve Mtundu
Axial flow silent check valve
Ndi axial flow silent check valve, mbale ya valve imagwiridwa ndi kasupe yomwe imayika mbale ya valve kuti ikhale yoyenda bwino komanso kutsegula ndi kutseka mwamsanga. Kasupe ndi diski zili pakati pa chitoliro, ndipo madzi amayenda mozungulira diski. Izi ndizosiyana ndi ma valve ogwedezeka kapena mitundu ina ya mavavu a kasupe, omwe amakoka diski yonse kuchokera mumadzimadzi, ndikusiya chubu lotseguka.

Mapangidwe apadera a axial flow silent check valve amapangitsa kuti ikhale yokwera mtengo kuposa ma valve oyendera masika ndi swing check valves. Ngakhale kuti ndi okwera mtengo, kubweza ndalamazo kumabwera chifukwa cha moyo wawo wautali, zomwe zingatenge zaka zitatu kuti zisinthe.

Kumanga kwapadera kwa Axial Flow Quiet Check Valve kumakulolani kuti muwone pansipa pamene valve imatsegula ndi kutuluka kwa madzi. Mofanana ndi ma valve oyendera masika, ma axial check valves amayamba kutseka pamene kuthamanga kwamtunda kumatsika. Pamene kuthamanga kumachepa pang'onopang'ono, valavu imatseka pang'onopang'ono.

Mpira spring check valve
Ma valve oyendera mpira amagwiritsira ntchito mpira ngati mpando wosindikizira pafupi ndi dzenje lolowera. Mpando wosindikizira umapangidwa kuti uwongolere mpirawo ndikulowamo ndikupanga chisindikizo chabwino. Pamene kukanikiza kochokera kumayendedwe kumakhala kwakukulu kuposa kasupe komwe kamagwira mpira, mpirawo umasunthidwa,
