阀门的保养方法：　　1、长期存放的阀门，应作定期检查，对外露的加工表面须保持清洁，清除污垢，存放时球阀应两端堵塞并处于开启状态，闸阀、截止阀、止回阀，通道的两端应堵塞并处于关闭状态，整齐地存放在室内通风干燥的地方，严禁堆置或露天存放。　　2、安装前，必须仔细核对本阀标志的压力，通径是否符合使用要求，消除运输过程所造成的缺陷，并消除阀件的污垢。　　3、安装时，可将阀门按连接方式直接装置在管路上。一般情况下，可安装在管路任意位置上，但需便于操作的检修，注意截止阀介质流向应是纵阀瓣下面往上流，升降式止回阀只能水平安装。　　4、球阀、截止阀、闸阀使用时，只作全开或全闭，不允许做调节流量用，以免密封面受冲蚀，加速磨损。闸阀和上螺纹截止阀内有倒密封装置，手轮旋至最上位置拧紧，即可阻止介质从填料处泄漏。　　5、球阀、截止阀、闸阀开、关时应用手轮，请勿借助杠杆或其它工具，以免损坏阀件。手轮顺时针旋转为关闭，反之为开启。　　6、填料压盖的螺栓应均匀地拧紧，不应压成歪状态，以免碰伤阻碍阀杆运动或造成泄漏．　　　　7、阀门在使用过程中，应经常保持清洁，传动螺纹必须定期润滑，发现故障时，应立即停止使用，查明原因清除故障。

Maintenance of the valve: 1, the long-term storage of the valve, should be regularly checked, the processing of the exposed surfaces shall be clean and remove dirt, when the ball should be placed at both ends and plug in the open, gate valve, globe valve, check valve, channel both ends of the block and should be turned off, neatly stored in the room ventilated, dry place, stacked or open storage is prohibited. 2, the installation, you must carefully check the sign of the pressure valve, path meets the requirements, to eliminate defects caused by the transport process, and eliminate the valves of the dirt. 3, the installation can be connected directly by the valve device in piping. Under normal circumstances, can be installed anywhere in the pipeline, but need to facilitate the operation of the maintenance, pay attention to media flow valve shall be vertical upward flow below the valve, lift check valve can be installed horizontally. 4, ball valve, globe valve, gate valve used only for the fully open or fully closed, adjust the flow is not allowed to do with, so the sealing surface by erosion, accelerated wear and tear. Thread on the valve and valve seal down inside, hand wheel rotation to tighten the top position, you can prevent media leaks from the filler. 5, ball valve, globe valve, gate valve opening and closing should be hand-wheel, do not use leverage or other tools to avoid damage to the valves. Hand-wheel clockwise to shut down, otherwise it is open. 6, the packing gland bolts should be tightened evenly and should not be pressed into a crooked state, so as not to bruise the stem impede movement or cause leaks. 7, the valve in use, should be kept clean, drive screw must be regularly lubricated, find fault, you should immediately stop using, identify the reasons clear the fault.
