Zambiri pa Check Valve

Pankhani yamapaipi amadzimadzi,chekeni valavus ndi zigawo zofunika. Amapangidwa kuti aziwongolera momwe madzi amayendera mu payipi ndikuletsa kubweza kapena kubwereranso. Nkhaniyi ifotokoza mfundo zoyambira, mitundu, ndi kagwiritsidwe ntchito ka ma cheke.

Mfundo yofunikira ya achekeni valavundi kugwiritsa ntchito kayendedwe ka valve disc kuti azitha kuyendetsa kayendedwe ka madzi. Disiki ya valve nthawi zambiri imapangidwa kuti itsegule njira yamadzimadzi yachibadwa ndikutseka mwamsanga pamene kubwerera kumapezeka. Kapangidwe kameneka kamalepheretsa madzimadzi kuyenda chammbuyo ndipo amateteza kukhulupirika kwa dongosolo la mapaipi.

Ma valve owunika amabwera m'mitundu yosiyanasiyana, omwe amapezeka kwambiri kuphatikiza mpirafufuzani ma valve, kusintha ma valve, ndi kukweza ma valve cheke. Ma valve cheke a mpira amagwiritsa ntchito chimbale chozungulira cha valve chomwe chimatseka kusiyanasiyana kwamadzimadzi. Ma valve oyendetsa ma swing ali ndi diski yozungulira yomwe imatha kutseguka kapena kutseka kuti iwongolere njira yoyenda. Ma valve okweza amagwiritsira ntchito chimbale cha valve chosunthika chomwe chimayikidwa mu payipi kuti akwaniritse kuwongolera koyenda.

Ma valve owunikira amakhala ndi ntchito zambiri m'magawo ambiri. M'machitidwe operekera madzi,fufuzani ma valveamagwiritsidwa ntchito kuteteza madzi kubwerera ndi kusunga madzi kuthamanga bata. M'makampani opanga mankhwala, ma valve owunika amalepheretsa kubweza kwa mankhwala owopsa m'mapaipi, potero amateteza zida ndi chitetezo cha ogwira ntchito. M'makampani amafuta ndi gasi, ma valavu owunika amagwiritsidwa ntchito kuteteza kubweza kwa mafuta ndi gasi ndikusunga magwiridwe antchito okhazikika a mapaipi. Kuphatikiza apo, ma cheke ma valve amagwiritsidwa ntchito kwambiri pochiza zimbudzi, makina opondereza moto, makina owongolera mpweya, ndi zina.

Kuonetsetsa kuti ma valve oyendera akugwira ntchito bwino, kukonzanso nthawi zonse ndi kuyang'anitsitsa ndikofunikira. Ma disc a valve ndi zosindikizira ziyenera kutsukidwa ndikusinthidwa nthawi ndi nthawi kuti zitsimikizire kuti zikugwira ntchito bwino. Kuphatikiza apo, kusankha ndi kukhazikitsa ma valavu a cheki kuyenera kuganiziridwa mosamalitsa potengera zomwe mukufuna kugwiritsa ntchito.

Pomaliza, ma cheki ma valve amagwira ntchito yofunika kwambiri pamapaipi powongolera njira yamadzimadzi ndikuletsa kubwereranso. Posankha mtundu woyenera wa valve yowunikira, kuonetsetsa kuti kuikidwa bwino, ndi kukonza nthawi zonse, chitetezo ndi ntchito yokhazikika ya dongosolo la payipi ikhoza kutsimikiziridwa.
