Posachedwapa, ntchito yopangira fakitale yathu yakhala ndi ntchito yolemetsa, yotulutsa ambirivalavu za airdamper, mpeni mavavu pachipata, ndi mavavu a zipata zamadzi. Ogwira ntchito m'misonkhanoyi ayika kale ma valve ochepetsa kuthamanga ndipo posachedwa awatumiza kunja.

Valavu yochepetsera kuthamangandi zida zomwe zimagwiritsidwa ntchito poyang'anira zamadzimadzi m'munda wa mafakitale, zomwe ntchito yake yayikulu ndikuchepetsa kuthamanga kwamadzi mpaka pamlingo wocheperako wofunikira. Mfundo yogwira ntchito ya mtengo wa valve kuchepetsa kuthamanga imachokera pa mfundo ya madzimadzimadzimadzi, omwe amayendetsa kuthamanga kwa madzi ndi kuthamanga kwa madzi mwa kusintha chipangizo chogwedeza mkati mwa thupi la valve. Madzi othamanga kwambiri akalowa mu valavu ya fakitale, mphamvu ya kinetic yamadzimadzi imakankhira pakati pa valve mmwamba, ndipo kasupe nawonso amapanikizika, zomwe zimapangitsa kuti valavu ikhale pansi. Pamene mphamvu pakati pa pakati pa valavu ndi kasupe ifika pamlingo wofanana, valavu yochepetsera mphamvu imagwira ntchito mokhazikika mkati mwazomwe zimayikidwa.

Ubwino wa ma valve ochepetsa kuthamanga:

1.Kukhazikika kwakukulu

Valavu yochepetsera kupanikizika imatha kusungabe kupanikizika kokhazikika, kuonetsetsa kuti dongosololi likuyenda bwino, ndikupewa kuwonongeka ndi kulephera komwe kumachitika chifukwa cha kusintha kwamphamvu.

2.Kutetezedwa kwakukulu

Mwa kuwongolera bwino kupanikizika, valavu yochepetsera madzi imatha kuletsa kupasuka kwa mapaipi kapena kuwonongeka kwa zida chifukwa cha kupanikizika kwambiri, kukonza chitetezo chadongosolo.

3.High mphamvu yopulumutsa mphamvu

Ma valve ochepetsa mphamvu amathandizira kuchepetsa kugwiritsa ntchito mphamvu zamagetsi, kuchepetsa kuwononga mphamvu, ndipo ndizofunikira kwambiri pakuteteza chilengedwe komanso kuteteza mphamvu.

4.Wide ntchito zosiyanasiyana

Ma valve ochepetsera mphamvu amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga petrochemicals, magetsi, mankhwala, chakudya, komanso njira zoperekera madzi m'mizinda, ndi ntchito zosiyanasiyana.

Monga chida chofunikira chowongolera madzimadzi, ma valve ochepetsa kuthamanga amatenga gawo lofunikira kwambiri pakupanga mafakitale amakono chifukwa cha kukhazikika kwawo, kotetezeka, komanso kupulumutsa mphamvu. Ndi kupita patsogolo kosalekeza kwaukadaulo, mtsogoloma valve ochepetsa kuthamangaadzakhala anzeru kwambiri ndi kothandiza, kupereka zitsimikizo odalirika kwambiri kupanga mafakitale. Ngati muli ndi zosowa zilizonse zogula, chonde titumizireni pansipa.
