軌道(dao)球閥(fa)GQ47H
傳統(tong)的球(qiu)閥，無(wu)論是(shi)浮動(dong)式還(hai)是固(gu)定式(shi)，球體(ti)與閥(fa)座💘始(shi)終接(jie)觸，開(kai)關扭(niu)矩大(da)，密封(feng)面容(rong)易👨🏻🏭亚洲中文字幕在线观看😁損(sun)傷，軌(gui)道球(qiu)閥在(zai)啟閉(bi)時，球(qiu)體先(xian)偏轉(zhuan)-δ角，然(ran)後轉(zhuan)動，開(kai)關全(quan)過程(cheng)👧🏾中球(qiu)體與(yu)閥座(zuo)脫離(li)，故閥(fa)座不(bu)👋會被(bei)擦傷(shang)，并且(qie)啟閉(bi)扭矩(ju)小。
