Pa malo akuluakulu opopera madzi, mapulojekiti osamalira madzi ndi zomangamanga zoperekera madzi m'matauni, chitetezo cha nyundo yothira madzi, chitetezo cha kulephera kwa magetsi mwadzidzidzi komanso kukonza malo a mapaipi ndi njira zofunika kwambiri zowunikira makontrakitala a EPC ndi mabungwe opanga mapulani panthawi yosankha zida za mapaipi akuluakulu.valavu ya gulugufe ya hayidirolikiYokhala ndi silinda yamafuta yotseka pang'onopang'ono komanso thupi la valavu yachitsulo ya S355J imagwiritsidwa ntchito kwambiri ngati yankho lodalirika la makina otulutsira mapaipi.

Chopangidwa ndi chitsulo chopangidwa ndi S355J chopanda alloy, thupi la valavu limapereka kulimba kodabwitsa kwa kutentha kochepa komanso kusinthasintha kwabwino poyerekeza ndi njira zina zachitsulo chopangidwa ndi chitsulo. Limatha kugwira ntchito mokhazikika pansi pa PN16 pressure rating m'malo ovuta kuphatikiza malo otseguka komanso madera otentha pang'ono. Kapangidwe kake kopangidwa ndi valavu kamakhala ndi kulimba kwakukulu komanso kukana kusintha kwa mavavu achikhalidwe, zomwe ndizofunikira kwambiri pakukula kwa DN1000 nominella.

Valavu iyi imagwiritsa ntchito njira yosungira mphamvu yolimbana ndi kulemera kwa magetsi komanso silinda yotseka pang'onopang'ono ya hydraulic. Choyatsira magetsi chimatsegula valavu ndikukweza mphamvu yolimbana ndi kulemera kwa magetsi kuti isunge mphamvu yokoka nthawi imodzi. Pazifukwa zadzidzidzi monga kuzima kwa magetsi kapena kutayika kwa mphamvu yamagetsi, mphamvu yosungidwa ya mphamvu yolimbana ndi kulemera kwa magetsi imayendetsa valavu kuti izitseke yokha. Pamodzi ndi silinda yamafuta osungira magetsi, imakwaniritsa njira yotsekera yosinthika ya magawo awiri: kutseka mwachangu kusanachitike kutsatiridwa ndi kutseka pang'onopang'ono komaliza. Njirayi imaletsa bwino kukwera kwa mphamvu ya nyundo yamadzi komwe kumachitika panthawi yotseka pampu ndikuletsa kuwonongeka kwa mapaipi ndi ma pampu.

Imagwirizanitsa ntchito za valavu yodzipatula ndi valavu yoyang'anira yosabwezera. Chigawo chimodzi chingalowe m'malo mwa valavu yoyang'anira ya chipata ndi valavu yoyang'anira, zomwe zimapangitsa kuti pakhale kusinthasintha kwa mapaipi, kuchepetsa ndalama zogwirira ntchito zomangamanga, ntchito yoyika pamalopo komanso ndalama zogwirira ntchito yokonza nthawi yayitali. Ili ndi zida zochepetsera mphamvu zamagetsi ndi masensa oyankha malo, valavuyi imagwirizana ndi makina owongolera odziyimira pawokha a PLC ndipo imathandizira kugwira ntchito kwamanja kwanuko komanso kulamulira kwakutali kwa interlock. Ndi yoyenera malo opopera madzi okha, malo opangira magetsi, kugawa madzi m'matauni, kuchotsa mchere m'madzi ndi malo ena oyendera madzi.

Ma valve achikhalidwe akuluakulu ali ndi zofooka zazikulu: liwiro lotseka losalamulirika, kusowa chitetezo chokhazikika pamene magetsi alephera, komanso mphamvu zosakwanira za ma valve akuluakulu. Valavu ya gulugufe ya hydraulic counterweight iyi yokhala ndi thupi la S355J imathetsa mavuto ofala awa kudzera muzinthu zokonzedwa bwino, njira yoyendetsera yokhwima komanso njira yodalirika yowongolera. Imasunga mphamvu yotsika yolimbana ndi madzi, magwiridwe antchito okhazikika komanso kulephera kochepa panthawi yogwira ntchito nthawi yayitali. Yakhala njira yodziwika bwino m'mapulojekiti apadziko lonse lapansi osungira madzi ndi zomangamanga zamadzi. Nthawi yotsegulira ndi kutseka yokonzedwa, chophimba choteteza dzimbiri ndi ma phukusi owongolera madzi ofanana amapezeka malinga ndi momwe malo amagwirira ntchito.

Kwa ogula mainjiniya apadziko lonse lapansi, chitsulo cha S355J chimagwirizana ndi miyezo ya zinthu zaku Europe, zomwe zimathandiza kuwunika zinthu ndi kuvomereza mapulojekiti akunja ku Europe, Southeast Asia, Middle East ndi madera ena. Silinda ya buffer imalola kusintha pang'onopang'ono ngodya ndi nthawi yotseka. Mainjiniya amatha kulinganiza bwino momwe nyundo yamadzi imagwirira ntchito kutengera kutalika kwa payipi yeniyeni, liwiro la madzi ndi mawonekedwe apakati.

Kupatula madzi oyera, valavu imatha kukonzedwa kuti igwire ntchito yokonza madzi osaphika ndi matope pang'ono komanso madzi a m'nyanja osakhuthala kwambiri ndi mankhwala apadera oletsa dzimbiri pamwamba. Chipangizo chothandizira cha hydraulic ndi chaching'ono komanso chosavuta kugwiritsa ntchito pokonza nthawi zonse; zida zosinthira za silinda yamafuta ndi zomangira zotsutsana ndi kulemera zimapezeka padziko lonse lapansi kuti zithandizire ntchito yakumaloko yogulitsa pambuyo pogulitsa. Poyerekeza ndi zida zina zochepetsera nyundo yamadzi monga matanki oyendera ndi zombo zamlengalenga, yankho la valavu iyi yonse imachepetsa bajeti yonse ya polojekiti ndipo imakhala ndi malo ochepa mkati mwa nyumba zopopera, zomwe ndi zabwino kwambiri pamapulojekiti omwe ali ndi chipinda chochepa.
