Kukula kwa valavu ya cheki kumakhala ndi ubale wosalekanitsidwa ndi mabizinesi amakampani.M'mabizinesi akutukuka, kugwiritsa ntchito ma valavu ndikofunikira.Kuti agwirizane ndi zomwe zikuchitika m'mabizinesi osiyanasiyana amakampani, opanga ma valavu ayenera kupanga kusintha kwazinthu ndi zatsopano kuti athe kuthana ndi kufulumira kwamakampani opanga mafakitale.

Kupititsa patsogolo khalidwe la valve cheki

Poyerekeza ndi ukadaulo wosavuta komanso wopanda pake wopanga ma valavu a cheke, ukadaulo wamakono wopanga ukupita patsogolo kwambiri ndipo mtundu wa valavu yowunikira wakhala wabwino kwambiri.Ntchito imakulitsidwanso.Zogulitsa zatsopano zama valve zokhala ndi ntchito zosiyanasiyana zimatuluka monga lift check valve, swing check valve ndi flue check valve, zomwe zidzasintha dziko lapansi.

Kusankha zida zopangira valavu

Anthu amakono akufunafuna kutsika kwa carbon ndi kuteteza chilengedwe, momwemonso valavu yowunika.Kupita patsogolo kwaukadaulo kumapangitsa kuti valavu yowunika ikhale yopepuka komanso yowoneka bwino.Pamene mapangidwe apangidwe, phokoso, zipangizo, mapaipi ndi zinthu zina zaphunziridwa kale bwino kuti ma check valves agwiritsidwe ntchito bwino m'mabizinesi amakono a mafakitale.

Padziko lonse lapansi, chitukuko cha valve cheki chimagwera kumbuyo.Komabe, kwa anthu omwe akutukuka kwambiri, kufulumira kwa ma valve ku China sikungafanane ndi opanga ma valve ena apadziko lonse lapansi.M'tsogolomu, zinthu za valve check valve za China zidzabweretsa lingaliro latsopano pakupanga ma valve padziko lonse lapansi ndipo zatsopano zomwe zingabweretse chitukuko chabwino ku China.
