Yang'anani Mfundo Yoyika Ma valve ndi Njira Zodzitetezera

Onani valavuimatchedwansovalavu imodzikapena cheke valavu, ntchito yake ndikuletsa sing'anga mu payipi kuti isabwerere.Valavu yomwe imatsegula kapena kutseka yokha mwa kuyenda ndi mphamvu yapakati kuti ateteze sing'anga kubwerera mmbuyo imatchedwa check valve.Ma valve owunika ali m'gulu la ma valve otomatiki.Ma valve owunikira amagwiritsidwa ntchito makamaka m'mapaipi pomwe sing'anga imayenda mbali imodzi, ndipo amangolola sing'anga kuyenda mbali imodzi kuti apewe ngozi.

Malinga ndi kapangidwe ka valavu cheke, akhoza kugawidwa mu mitundu itatu:valavu yowunikira, valavu yoyenderandivalavu ya butterfly.Ma valve okwera amatha kugawidwa m'mitundu iwiri:ma vertical check valvesndizopingasa cheke mavavu.The swing check valve imagawidwa m'magulu atatu:single plate check valve, valavu yoyendera mbale ziwirindi ma multiplate check valve.

Zinthu zotsatirazi ziyenera kutsatiridwa poika valavu yoyendera:

1.Musalole kuti valavu yowunika ikhale yolemera mu payipi.Ma valve akuluakulu a cheki ayenera kuthandizidwa paokha kuti asakhudzidwe ndi kupanikizika komwe kumapangidwa ndi makina a mapaipi.
2.Pakuyika, tcherani khutu ku kayendetsedwe ka kayendedwe kapakati kayenera kukhala kogwirizana ndi njira ya muvi wolembedwa pa thupi la valve.
3.Kukweza valavu yoyang'ana yoyimaayenera kuikidwa pa payipi ofukula.
4.TheNyamulani chopingasa chopingasa chotchinga valavuayenera kuikidwa pa payipi yopingasa.

Malingaliro oyika:

1.Poyika payipi, tcherani khutu kupanga njira yodutsa valve yoyang'ana pansimogwirizana ndi otaya malangizo a madzimadzi, anaika mu ofukula payipi;Kwa mapaipi opingasa, ikani valavu yoyang'ana kabati molunjika.
2.Gwiritsani ntchito chubu cha telescopic pakati pa valve yoyang'ana kavalo ndi valavu ya butterfly, musamalumikizane ndi ma valve ena.
3.Pewani kuwonjezera zitoliro za chitoliro ndi zotchinga mkati mwa utali wogwirira ntchito wa mbale ya valve.
4.Musayike chochepetsera kutsogolo kapena kumbuyo kwa valve yowunikira.
5.Mukayika valavu yoyang'ana kavalo kuzungulira chigongono, tcherani khutu kusiya malo okwanira.
6.Mukayika valavu yoyang'ana pamphuno, siyani malo osachepera kasanu ndi kasanu ndi awiri a valve kuti muwonetsetse kuti mbale ya butterfly imakhudzidwa ndi madzi.
