Lero, fakitale ya Jinbin idamaliza kuyika valavu yachipata chachikulu cha DN700. Izivalavu ya sulice gateyakonzedwa mosamalitsa ndi kukonza zolakwika ndi antchito, ndipo tsopano yadzaza ndi kukonzekera kutumizidwa komwe ikupita.

Ma valve akuluakulu a zipata ali ndi ubwino wotsatirawu:

Kuthamanga kwa 1.Kuthamanga kwamphamvu: Kupanga kwakukulu kwa m'mimba mwake kumapangitsa kuti madzi ambiri azitha kudutsa, kuchepetsa kukana kwamadzimadzi komanso kuonetsetsa kuti madzi akuyenda bwino.

2.Kugwira ntchito bwino kusindikiza: Kugwiritsa ntchito zipangizo zosindikizira zapamwamba zimatha kuteteza bwino kutuluka kwamadzimadzi ndikuonetsetsa kuti dongosololi likuyenda bwino.

3.Easy kugwira ntchito: Nthawi zambiri amagwiritsidwa ntchito ndi handwheel kapena actuator yamagetsi, yomwe imakhala yosavuta kugwira ntchito ndipo imatha kukwaniritsa kutsegula ndi kutseka mwamsanga.

4.Yokhazikika komanso yodalirika: Mapangidwe ake ndi olimba, okhoza kupirira kupanikizika kwakukulu ndi mphamvu zowonongeka, ndipo amakhala ndi moyo wautali wautumiki.

Chipata chachikulu cha ductile iron chipata cha valve nthawi zambiri chimagwiritsidwa ntchito pazifukwa izi:

1.Makina osungira madzi: M'madamu akuluakulu, malo osungiramo madzi ndi malo ena osungira madzi, ma valve olowera m'mimba mwake amagwiritsidwa ntchito kuti athetse kutuluka ndi kutuluka kwa madzi ndikuyendetsa madzi.

2. Madzi amadzimadzi ndi njira zoyendetsera madzi: M'mapaipi amadzi a m'tauni ndi kukhetsa madzi, valavu ya chipata cha madzi a m'mimba mwake ingagwiritsidwe ntchito kuyang'anira njira ndi kayendedwe ka madzi, kuonetsetsa kuti madzi akuyenda bwino.

3. Petrochemical industry: Mu machitidwe a mapaipi m'mafakitale monga petroleum ndi mankhwala, ma valve a zipata zazikulu amagwiritsidwa ntchito kuwongolera kutuluka kwa zakumwa zosiyanasiyana ndi mpweya, kuteteza kutuluka ndi ngozi.

4.Mphamvu yamagetsi: M'mafakitale opangira magetsi, malo opangira magetsi ndi magetsi ena, ma valve a zipata zazikulu za m'mimba mwake amagwiritsidwa ntchito kuti azitha kuyendetsa madzi monga madzi ozizira ndi nthunzi, kuonetsetsa kuti zipangizo zikuyenda bwino.

5.Kuthira madzi amadzimadzi: M'mafakitale osungira madzi onyansa, valve ya chipata chachikulu cha flange imagwiritsidwa ntchito poyang'anira kayendedwe ka madzi onyansa, kuonetsetsa kuti njira yothetsera madzi akuyenda bwino.

Chifukwa chake,valavu yachipata chachikulumtengo wakhala ukugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga uinjiniya wosungira madzi, makina operekera madzi ndi ngalande, mafuta a petrochemicals, mafakitale amagetsi, ndikuthira zimbudzi chifukwa cha mphamvu yothamanga kwambiri, kusindikiza bwino, kugwira ntchito kosavuta, kulimba, komanso kudalirika.
