低壓暗桿鑄鋼閘閥 Z45H-10C
Z45H-10C低壓暗桿鑄鋼閘閥，是良科研發的新型產品，替代傳統鑄鐵閥門，結構緊(jin)湊、設計(ji)合理、閥(fa)門剛(gang)性好，通(tong)道(dao)流暢(chang)、流阻系(xi)數小(xiao)。密封面采用(yong)(yong)不(bu)銹(xiu)鋼和硬(ying)質(zhi)合金，使(shi)用(yong)(yong)壽命長。采用(yong)(yong)柔性石墨填(tian)料、密封可靠、操作輕便靈活。驅(qu)動(dong)(dong)方(fang)式分手動(dong)(dong)、電(dian)動(dong)(dong)、氣動(dong)(dong)、齒輪傳動(dong)(dong)；結構型(xing)(xing)：彈性楔式單閘(zha)板(ban)(ban)、剛(gang)性楔式單閘(zha)板(ban)(ban)和雙閘(zha)板(ban)(ban)型(xing)(xing)式。廣泛適用(yong)(yong)于石油化(hua)工，冶金，水處理，火力發電(dian)廠等(deng)油品、水蒸汽管(guan)(guan)路上(shang)作接通(tong)或截斷管(guan)(guan)路中介(jie)質(zhi)的啟閉裝置。
