F743X-1型液動扇(shan)形盲板閥(fa)
概述
液動扇(shan)形盲(mang)板(ban)閥(fa)主機(ji)由左閥(fa)體(ti)、右閥(fa)體(ti)、齒圈(quan)、絲杠(gang)付、閥(fa)板(ban)、密封圈(quan)等零(ling)件組(zu)成。并由底座、支撐(cheng)柱構成一個鋼性結(jie)構體(ti)。
閥門(men)中設有啟閉油(you)缸(gang)和翻(fan)板(ban)油(you)缸(gang)。癖閉油(you)缸(gang)通過齒圈、齒輪和絲(si)杠螺旋付驅動(dong)(dong)(dong)左、右閥體完(wan)成(cheng)松開(kai)、夾緊動(dong)(dong)(dong)作(zuo)，翻(fan)板(ban)油(you)缸(gang)驅動(dong)(dong)(dong)閥板(ban)完(wan)成(cheng)開(kai)閉動(dong)(dong)(dong)作(zuo)。橡膠密封圈鑲嵌在(zai)閥板(ban)上，密封性能好、更換(huan)放(fang)便。
本閥有正裝(zhuang)結構(gou)（型(xing)號(hao)(hao)：），也有倒(dao)裝(zhuang)結構(gou)（型(xing)號(hao)(hao)：FD743X-0.5）。安(an)裝(zhuang)時請(qing)參(can)照(zhao)圖中所示(shi)確定安(an)裝(zhuang)方便。
液(ye)(ye)動(dong)扇形盲板(ban)閥分電(dian)(dian)(dian)(dian)液(ye)(ye)控(kong)(kong)和全(quan)液(ye)(ye)控(kong)(kong)兩(liang)種，電(dian)(dian)(dian)(dian)液(ye)(ye)控(kong)(kong)靠(kao)防爆電(dian)(dian)(dian)(dian)氣行程開關發(fa)生(sheng)位(wei)置電(dian)(dian)(dian)(dian)信(xin)(xin)號控(kong)(kong)制電(dian)(dian)(dian)(dian)磁閥動(dong)作。全(quan)液(ye)(ye)控(kong)(kong)利用二位(wei)二通閥做限(xian)位(wei)元件，通過液(ye)(ye)壓油接通壓力繼(ji)(ji)電(dian)(dian)(dian)(dian)器產生(sheng)電(dian)(dian)(dian)(dian)信(xin)(xin)號控(kong)(kong)制電(dian)(dian)(dian)(dian)磁閥動(dong)作。全(quan)液(ye)(ye)控(kong)(kong)方式壓力繼(ji)(ji)電(dian)(dian)(dian)(dian)器安裝在液(ye)(ye)壓站上，遠離閥門，因(yin)此防爆性能(neng)更好。
