Chotsekera valavu chimagwiritsidwa ntchito makamaka kutseka valavu kuti isatsegulidwe ndi ena.Tsopano imagwiritsidwa ntchito makamaka ndi wogula valve.Kutseka kwa valve ndikofunikira.Kodi loko ya valve imapangidwa bwanji?Tiyeni timvetse maziko a mapangidwe pamodzi.

Mavavu okhala ndi zida zokhoma pamapaipi amadzi, mapaipi otenthetsera kapena mapaipi agesi amagwiritsidwa ntchito kwambiri.Ngakhale kapangidwe ka valavu yotsekera ndi yosiyana, ambiri aiwo amagwiritsa ntchito makina otsekera thupi ndikugwiritsa ntchito kiyi kuti atsegule.Njirayi ndi yotetezeka komanso yodalirika, koma pamene chiwerengero cha ma valve otsekemera ndi aakulu ndipo fungulo limasungidwa ndi munthu wodzipatulira, popeza makiyi omwe amagwiritsidwa ntchito ndi valve iliyonse sangathe kugwiritsidwa ntchito ponseponse, sizothandiza kuti asamayendetse pakati, komanso ndizovuta kwambiri kwa ogwira ntchito yosungiramo zinthu kuti azinyamula ndikugwira ntchito.

Kuti zimenezi zitheke, anthu asintha zinthu zosiyanasiyana.Mwachitsanzo, mabuku achi China patent amawulula valve yotsekera maginito [nambala yofunsira: 200610071229.X;nambala yolengeza yovomerezeka: CN100590333C], yomwe imaphatikizapo thupi la valavu ndi valavu yomwe imayikidwa mu thupi la valve, pachimake ndi tsinde la valve, ndi chida chotsegula chomwe chimagwiritsidwa ntchito kutsegula ndi kutseka thupi la valve ndipo limatha kupatukana ndi thupi la valve.Mzere wokhoma umaperekedwa pa thupi la valve pomwe tsinde la valve limafikira.Tsinde la valve limadutsa pamzere wokhoma.Mapeto akunja amatuluka pakhoma, ndipo kumapeto kwamkati kumalumikizidwa ndi pakati pa valve.Tsinde la valavu limaperekedwa ndi chivundikiro cha loko chomangirira pamwamba pa ndime ya loko.Chida chotsekera maginito chimaperekedwa pakati pa chivundikiro cha loko ndi chipilala chotchinga kuti chichepetse kuzungulira kwa ziwirizo.Bowo lotsekera lokhala ndi mawonekedwe osazungulira ozungulira limatsegulidwa pakatikati pa tsinde la valavu.Chida chotsegula chimaperekedwa ndi thupi lotsegula lomwe likugwirizana ndi mawonekedwe amtundu wa dzenje lotsekera, ndipo chida chotsegula chimaperekedwa ndi maginito okhazikika omwe amatha kulamulira chipangizo chotseka maginito.Chophimbacho ndi chivundikiro cha loko zimaphatikizidwa.

Maginito otsekera ma valve amtundu woterewa amagwiritsa ntchito mfundo yothamangitsira mlingo womwewo wa maginito osatha, ndipo ma valve onse otsekemera amatha kutsegulidwa ndi chida chotsegula, chomwe chimasinthasintha kwambiri;komabe, kwa maginito otsekera maginito amtundu woterewu, mawonekedwe ozungulira a tsinde la valve ndi ochepa, mkati mwa madigiri a 90, angagwiritsidwe ntchito pa ma valve a mpira, ndipo kukula kwake kumakhala kochepa.
