Pochiza dzimbiri lomwe lilipo, akatswiri amatha kugwiritsa ntchito maburashi a waya kapena kuphulika kwa mchenga kuti achotse dzimbiri. Kugwiritsa ntchito choletsa dzimbiri kapena pulasitala pambuyo pake kumateteza valavu kuti isawonongeke kwambiri. Pa milandu yoopsa, kusintha ziwalo zomwe zakhudzidwa ndi dzimbiri kungakhale kofunikira. Kusamalira nthawi zonse kumaonetsetsa kuti mavalavuwo akugwirabe ntchito komanso akutsatira miyezo ya NFPA 291.
Kukonza ma valve omangika kapena ovuta kuwatembenuza
Ma valve otsekeka kapena ovuta kutembenuza nthawi zambiri amakhala chifukwa cha mafuta osakwanira, ma tsinde opindika, kapena dzimbiri mu valavu yayikulu. Njira zotsatirazi zingathandize kuthetsa mavuto awa:
- Onjezani mafuta kudzera mu pulagi yodzaza mafuta kuti muwonetsetse kuti mafutawo ndi abwino.
- Yang'anani tsinde kuti lione ngati likupindika chifukwa cha kulimba kwambiri. Bwezerani tsinde ngati pakufunika kutero.
- Pa ma hydrant akale, yang'anani ngati pali dzimbiri kapena malo osungira mu valavu yayikulu. Kukonza valavu kungathandize kubwezeretsa magwiridwe antchito.
- Ngati hydrant ili ndi zaka zoposa makumi asanu, kuisintha kungakhale njira yabwino kwambiri yothetsera vutoli.
Malangizo othandizira kuthetsa mavuto a ma payipi ozimitsa moto ndi ma valavu a pachipata amapereka chithandizo chowonjezera pozindikira ndikuthetsa mavutowa. Kupaka mafuta ndi kuwunika pafupipafupi kumatha kuletsa ma valavu kuti asatseke, ndikuwonetsetsa kuti akuyenda bwino panthawi yamavuto.
Kuzindikira ndi kuthetsa kuthamanga kwa madzi pang'ono
Kuthamanga kochepa kwa madzi m'ma valve amadzi otenthetsera moto kungalepheretse ntchito yozimitsa moto. Zomwe zimayambitsa nthawi zambiri zimaphatikizapo kutsekeka kwa hydrant, ma valve otsekedwa m'madzi oyenda, kapena mavuto a dongosolo lonse. Kuzindikira molondola kumafuna kuyeza kuthamanga kwa madzi ndi kuchuluka kwa madzi pogwiritsa ntchito zida zapadera. Gome ili pansipa likuwonetsa deta yofunika kwambiri ya magwiridwe antchito:
