Valavu yoyang'ana pa swing imatengera mawonekedwe opindika a rocker, ndipo mbali zonse zotsegula ndi zotseka za valve zimayikidwa mkati mwa thupi la valve.
Sichimalowa mu thupi la valve, kupatulapo gasket yosindikizira ndi mphete yosindikizira ya mbali yapakati ya flange, palibe malo otsekemera onse, kuchotsa valavu.
Kutuluka kunja. Mkono wa rocker wa swing check valve ndi kugwirizana kwa disc ndizozungulira kotero kuti diski ili pamtunda wa 360-degree.
Pali mlingo wina wa ufulu mkati, ndipo pali yoyenera yaing'ono udindo malipiro.
Ma valve a swing check amatsegulidwa kwathunthu ndipo kuthamanga kwamadzimadzi kumakhala kosalekeza ndipo kumadutsa kupanikizika kwa valve
Dontholo ndi laling'ono.
Ndi oyenera TV woyera, si oyenera TV munali particles olimba ndi mamasukidwe akayendedwe lalikulu.
Diski ya valavu yoyang'ana swing imazungulira mozungulira mozungulira. Kukana kwake kwamadzimadzi nthawi zambiri kumakhala kocheperako poyerekeza ndi ma valve okweza,
Yoyenera pamapulogalamu okulirapo.
Valavu yokweza ndi njira imodzi yowunikira valve, pamene sing'anga imayenda motsatira njira yabwino, diski imatsegula pansi pa mphamvu ya madzi;
Pamene sing'anga imayenda mosiyana, chimbalecho chimatseka pansi pa mphamvu yokoka ndikusintha kuthamanga kwamadzimadzi, kuchepetsa njira.
Valavu imatenga mawonekedwe okweza, omwe sali ochepa ndi malangizo oyika. Thupi la valve ndi bonnet zimasindikizidwa ndi ma gaskets achitsulo.
Otetezeka komanso otetezeka. Kusindikiza pamwamba pa diski ya valve ndi mpando wa valve amapangidwa ndi Sitaili cobalt-based carbide overlay welding, yomwe imakhala yolimba kwambiri komanso kukana kuvala.
Kukana kwa corrosion, ntchito yabwino yolimbana ndi mikangano, moyo wautali. Pambuyo popera, mapeto ake ndi apamwamba kwambiri, ndipo kusindikiza kumakhala kokhazikika komanso kodalirika. Chimbale
Malo osindikizira a cone akutsogolo amangogwirizana ndi mpando wa valve. Posindikiza, madzimadzi omwewo amagwiritsidwa ntchito kuti abwererenso kuthamanga, ndipo kuthamanga kwa kubwerera kumakhala kolimba
Kuchita bwino kosindikiza.
Valavu yonyamulira imakhala ndi kukana kwakukulu ndipo nthawi zambiri imayikidwa paipi yachitsime wamba.
