水力控制阀100X-900X是一种利用水自润式阀体,无须另加机油润滑,如遇主阀内零部件损坏时,请按下列指示进行拆卸。(注:内阀内一般消耗损伤品为膜片和○型圈,其它内部零件损伤甚少)
先将主阀前后端闸阀关闭。将主阀盖上的配管接头螺丝松开,释放阀内压力。将所有螺丝取下,包括控制管路中的必要铜管的螺帽。取阀盖和弹簧。将轴芯、膜片、活塞等取下,切勿损伤膜片。将以上各项东西取出后,检查膜片及○型圈是否损坏;如无损坏请勿再分自行争其内部零件如发现膜片或○型圈有损坏,请将轴芯上的螺帽松脱,逐浙分解出膜片或型圈,取出后重新换上新的膜片或○型圈。详细检视主阀内部阀座、轴芯等是否有损坏,若有其它杂物在主阀内部将其清理出。依反向是顺序将更换后的零部件组合装好主阀,注意阀门不能有卡阻现象。
