Mbiri yamakampani opanga ma valve
Kuyang'ana kumbuyo komwe kunayambira valavu, iyenera kubwereranso ku chinthu chamatabwa m'mabwinja akale a ku Aigupto omwe ankaganiziridwa kuti ndi valve mu 1000 AD. Kale mu nthawi ya Aroma, panali kale mapaipi m'nyumba za anthu olemekezeka ndi mavavu amkuwa kuti atumize kunja.
Pambuyo pake, luso la valve linakonzedwanso. Ndi kuwongolera kwaukadaulo wopanga ma valve achitsulo, njira zatsopano zoponyera zidakhazikitsidwanso ndipo zida zidasinthidwa. Vavu yachitsulo imatenga makina ogwira ntchito amphamvu, ndipo kulondola kwake kwasinthidwanso.
Pofuna kuthana ndi kusowa kwa madzi pomanga mapaipi, malamulo a phokoso okhudzana ndi malo opangira zinthu, komanso kupititsa patsogolo chitetezo cha gasi, ma valvewa amaphatikiza ma anti-corrosion valves amapaipi operekera madzi, ma valve otsika phokoso ochepetsera phokoso loyenda, matepi a socket, ndi kukangana. Kutembenuka kwa mapulagi a gasi a silika.
Tsopano tayambitsamakina apadera a valvendimakina opangira ma valveamene akhoza kuchita izi. Pambuyo pakusintha kangapo, chida chodulira chapano chimafika 10mm. Ndizothandiza, zosavuta, zokhazikika komanso zodalirika. Imaperekedwa pokonza zitsulo zonyezimira, zitsulo zotayidwa, mavavu a pachipata, mavavu apadziko lonse lapansi, mavavu a Gulugufe, zigongono, etc.
