padding: 0px; font-family: 宋体;"/>1.闸板移动改为齿轮齿条移动。煤斗闸门的设置主要是为检修锅炉时用，或控制煤的流量之用，是不常开常闭的。原闸门闸板的移动是丝杆活令带动闸板移动，时间长后，丝杆活令会生锈，致使闸板开闭不灵，失去作用。R302封闭式煤斗闸门的闸板移动改为齿轮齿条带动，齿轮齿条的接触范围很小，长时间使用后不会锈在一起，减少了开闭的阻力、�br data-filtered="filtered" style="margin: 0px; padding: 0px; font-family: 宋体;"/>2.闸板轨道设置在十八套支承滚轮上。原闸门的闸板轨道是由两根角钢制成，煤从上口落下后，不可避免的有很多煤块，煤屑卡在轨道里，致使闸板开闭失灵。R302封闭式煤斗闸门的闸板轨道是装在闸门内侧的园滚轮，闸板在滚轮上，煤从上口落下后，煤块和煤屑就无轨道可卡，闸板又在滚轮上移动，开闭的力自然小得多，而且轻便灵活、�br data-filtered="filtered" style="margin: 0px; padding: 0px; font-family: 宋体;"/>3.闸门的外形呈封闭式。R302煤斗闸门四周是密封的，避免了煤粉粉尘飞扬，具有不透尘性能，能满足我国环保法规的要求、�br data-filtered="filtered" style="margin: 0px; padding: 0px; font-family: 宋体;"/>本闸门共有五种规格，每种又分四种型式的组合、�/span></p><table cellspacing="1" cellpadding="1" width="500"><tbody style="margin: 0px;
