Valavu yodziyendetsa yokha ndi valavu yomwe imagwiritsidwa ntchito kuwongolera kuthamanga kwamadzi, kuthamanga kwamadzi, komanso kutentha. Imatha kusintha yokha kuthamanga kwa potuluka kutengera kusintha kwa kuthamanga kwa inlet kuti ikhalebe yamphamvu nthawi zonse. Valavu yamtunduwu imagwiritsidwa ntchito kwambiri m'mafakitale, monga mankhwala, mafuta, mphamvu, etc.
Kuthamanga kosalekeza kosalekeza, kukhazikika kwa msana, kuthamanga kwa mpweya, ndi valavu yochepetsera nthunzi yamapaipi a nayitrogeni ndi mtundu wapadera wa valavu yodziyendetsa yokha yomwe imagwiritsidwa ntchito kwambiri pamapaipi a nayitrogeni. Ikhoza kusintha kokha kuthamanga ndi kuthamanga kwa nayitrogeni kuti ikhalebe yokhazikika yotsika mtengo. Mtundu uwu wa valve nthawi zambiri umakhala ndi zigawo monga thupi la valve, chivundikiro cha valve, mpando wa valve, valavu disc, kasupe, ndi zina zotero.
Tabu yoyerekeza kukula kwachitsanzo:
| Model | dzina lake (DN) | njira yolumikizira | kuthamanga kwa ntchito (MPa) | njira yoyenera |
|— | ——– | ——– | ——– | ——–|
|ZL-1 | 15-50 | kugwirizana kwa flange | 0.6-1.6 | mpweya wa nayitrogeni |
|ZL-2 | 50-80 | kugwirizana kwa flange | 1.0-2.5 | mpweya wa nayitrogeni |
|ZL-3 | 80-150 | kugwirizana kwa flange | 1.6-4.0 | mpweya wa nayitrogeni |
|ZL-4 | 150-200 | kugwirizana kwa flange | 2.5-6.4 | mpweya wa nayitrogeni |
|ZL-5 | 200-300 | kugwirizana kwa flange | 4.0-10.0 | mpweya wa nayitrogeni |
Miyeso yachitsanzo yomwe ili pamwambayi ndi yongotengera zokhazokha, ndipo kusankha kwapadera kuyenera kutsimikiziridwa malinga ndi momwe ntchito ikugwirira ntchito ndi zofunikira.
