Kodi Check Valve Ndi Chiyani?

Zinthu zomwe muyenera kuziganizira posankha valavu

Posankha valavu yowunikira, ndikofunikira kuchita kafukufuku wamtengo wapatali wa dongosolo linalake.Zomwe zimachitika nthawi zonse ndikuchepetsa mtengo pomwe mukupeza kutsika kwapang'onopang'ono komwe kungatheke, koma kwa ma valve owunika, chitetezo chapamwamba chimafanana ndi kutayika kwakukulu.Choncho, pofuna kuonetsetsa kuti chitetezo cha valve cheke, dongosolo lililonse liyenera kuyesedwa mosiyana, ndipo zinthu monga chiwopsezo cha nyundo yamadzi, kutayika kovomerezeka kovomerezeka, ndi zotsatira zandalama zoyika valavu yowunikira ziyenera kuganiziridwa pa nyundo ya madzi.

Kuti muthe kusankha valavu yoyenera yogwiritsira ntchito yanu, pali njira zambiri zomwe muyenera kuziganizira.Choyamba, palibe mtundu umodzi wa valavu yowunikira yomwe ili yabwino kwambiri pazochitika zonse, ndipo zosankha zosankhidwa sizofunika mofanana pazochitika zonse.

Zina mwazosankha zoyenera kuziganizira posankha valavu yoyendera

Zinthu zina zomwe mungafunike kuziganizira ndi kuyanjana kwamadzimadzi, mawonekedwe akuyenda, kutaya mutu, mawonekedwe osakhudzidwa, ndi mtengo wathunthu wa umwini.Kuti mupeze ntchito yabwino, ndikofunikira kusankha valavu molingana ndi mawonekedwe a njira zosiyanasiyana zoyika.

Madzi

Ma valve cheke onse amagwiritsidwa ntchito pochiza madzi ndi kuthira madzi otayira, koma kuthira madzi aiwisi / zonyansa kungayambitse mavuto.Posankha ma valve amadzimadziwa, muyenera kuganizira momwe kupezeka kwa zolimba kungakhudzire ntchito ya valve.

Makhalidwe oyenda

Ngati valavu yotsegula imatseka mofulumira kwambiri, ndizotheka kupewa slamming.Komabe, kutseka kwachangu sikulepheretsa kuphulika komwe kumachitika pamene pampu imayamba ndikutseka.Ngati valavu imatsegula (ndi kutseka) mwamsanga, kuthamanga kwa magazi kudzasintha mwadzidzidzi ndipo kuphulika kumakhala kosavuta.

Kutaya mutu

Kutayika kwa mutu wa valve ndi ntchito ya kuthamanga kwamadzimadzi.Kutayika kwa mutu wa valve kumakhudzidwa ndi kayendedwe ka kayendedwe ka kayendedwe kake ndi mkati mwa valve.Geometry ya thupi la valve ndi mapangidwe otseka amatsimikizira malo othamanga kudzera mu valve ndipo motero amakhudzanso mutu.

Kutayika kwa mutu kuyenera kuganiziridwa ndi kuphatikiza kwa mutu wosasunthika (womwe umayambitsidwa ndi kusiyana kwa kutalika) ndi mutu wachitsulo (woyambitsidwa ndi chitoliro ndi mkati mwa valve).Pazifukwa izi, pali njira zambiri za valve headloss ndi mtengo wake.Chofala kwambiri chikhoza kukhala choyezera cha kuchuluka kwa madzi omwe amadutsa mu valve ndi kutsika kwapakati pa nthawi inayake.Koma poyerekeza, zimaganiziridwa kuti resistivity Kv ndiye chisankho chabwino kwambiri.

Mtengo wonse wa umwini

Mtengo wa valavu yanu sungaphatikizepo zambiri kuposa mtengo wogula.Kuyika kwina, mtengo wofunikira kwambiri mwina kugula ndi kukhazikitsa, koma nthawi zina, kukonza kapena kuwononga mphamvu kungakhale kofunika kwambiri kapena kofunika kwambiri.Mukamagwiritsa ntchito mtengo ngati chiyeso chosankha valavu yowunikira, mtengo wonse wa moyo wa valve uyenera kuganiziridwa.Kawirikawiri, mawonekedwe a valve osavuta, amachepetsa zofunikira zosamalira.

Zinthu zopanda slam

Onani valavuslam imapangitsa kuti kupanikizika kwa dongosolo kusinthasintha.Chinthu choyamba pakuchita izi ndikubwezeretsanso kutuluka pamene mpope wayima.Izi zingayambitse kubweza kwina kudzera mu valavu valavu isanafike pamalo otsekedwa kwathunthu.Ndiye otaya m'mbuyo chatsekedwa, ndi kusintha kwa otaya mlingo otembenuka kinetic mphamvu ya madzimadzi mu kuthamanga.

Slam imamveka ngati phokoso lomwe limapangidwa pamene diski kapena mpira wa valve cheke ugunda mpando wa valve, ndipo umapanga phokoso lalikulu.Komabe, phokosoli silimayambitsidwa ndi kutsekedwa kwa thupi, koma ndi mafunde omveka opangidwa ndi ma spikes othamanga omwe amatambasula khoma la chubu.Kuti mupewe kugunda kwathunthu, valavu yowunikira iyenera kutsekedwa musanayambe kuthamanga kulikonse.Tsoka ilo, izi sizinachitike.Geometry ya valavu imatsimikizira kuchuluka kwa kubwerera komwe kudzachitika, kotero kuti valavu imatseka mofulumira, kuchepa pang'ono.
