Valavu ya mpira wachitsulo yopangidwa ndi chitsulo-1052-DN15
gawo
Vavu yamadzi ndi chida chofunikira chomwe chimagwiritsidwa ntchito kwambiri m'mapaipi amadzi, chomwe chimagwiritsidwa ntchito kuwongolera, kulamulira kapena kuletsa kuyenda kwa madzi. Ndi yoyenera kugwiritsidwa ntchito m'malo osiyanasiyana, kuphatikizapo mafakitale, mabizinesi, ndi mabanja.
Ma valve athu a mpira ali ndi chitsulo chopangidwa ndi A105, chomwe chimamenyedwa ndi kutentha kwambiri komanso kuthamanga kwambiri kuti chikhale cholimba komanso cholimba pa kutentha kwakukulu komanso kotsika. Thupi la valve ndi bonnet zimamalizidwa ndi mankhwala ofiira a satin otentha kwambiri, kutsatiridwa ndi njira yodzitsekera yokha ya Cu-Ni-Cr yomwe imapereka kukana kwa asidi ndi alkali. Mpando wa valve umatsekedwa ndi kapangidwe ka chisindikizo cha PTFE chodzipangira chokha, kuonetsetsa kuti kutayikira kwa madzi kumatetezedwa. Chosinthira chogwiriracho chimakhala ndi chikwama cholimba, chosatha kusweka chomwe chimaletsa kutsetsereka pozungulira, zomwe zimapangitsa kuti ntchito ikhale yosalala komanso yosavuta kugwiritsa ntchito. Pogwiritsa ntchito ukadaulo wa Germany wopangira kutentha, ma valve athu akuyimira kukweza kuposa ma valve achidziwitso achikhalidwe pankhani ya mtundu wa chitsulo chopangidwa. Kuyesa kwamphamvu kwa ma laboratories ambiri kwatsimikizira kuti ma valve athu a mpira amalimbana ndi kuthamanga kwambiri, mphamvu zotsutsana ndi kuzizira, kupirira kutentha kwambiri, kupewa dzimbiri, komanso malo olumikizirana opanda solder.
Chifukwa chake, ma valve athu amasunga magwiridwe antchito abwino ngakhale m'nyengo yozizira komanso yozizira, zomwe zimaonetsetsa kuti mapaipi ali olimba. Kaya akugwiritsidwa ntchito m'mizere yopanga mafakitale, m'nyumba zamalonda, kapena m'malo okhala madzi, ma valve athu amadzi amapereka magwiridwe antchito odalirika komanso olimba nthawi zonse. Zosankha za ma valve zomwe zimasinthasintha komanso njira zapadera zopangira zinthu zimathandiza kuti akwaniritse zosowa zosiyanasiyana komanso malo okhala. Mwachidule, ma valve athu amadzi amapatsa ogwiritsa ntchito mayankho odalirika komanso ogwira mtima, okhala ndi zitseko zachitsulo zopanga zotsika mtengo, maziko a ma valve ndi tsinde lopangidwa mwamakonda, komanso njira zapadera zothanirana ndi dzimbiri komanso kutentha kochepa kwambiri. Pa ntchito zonse, ma valve athu amadzi amatsimikizira kuti mapaipi amagwira ntchito bwino komanso motetezeka, ndipo amapereka magwiridwe antchito olimba komanso olimba m'malo okhala madzi. Zosankha zawo zosinthika komanso njira zapadera zopangira zinthu zimathandiza kuti ma valve athu akwaniritse zosowa zosiyanasiyana komanso zofunikira zachilengedwe.
