以下为要翻译的全文,
4.1阀门应存放在干燥通风的室内,严禁堆迭放置,温度宜保持0~35℃之间,相对湿度为50~80%之间.
4.2库存阀门的两端必须封口,以防异物进入内腔而损伤密封部件.且应避免与油类或其它易燃物品接触.
4.3阀门的金属加工表面应清除污垢,并涂以防锈剂.
4.4安装前,应仔细核对管路的运行条件是否与本阀规定的适用范围相符,避免因选用不当而造成不必要的损失
4.5本阀除不宜应用于真空管路外,可在管路的任意位置安装作双向流动.当阀门处于卧装位置时,应在其装置下端加置支架加以固定,并应确保操作和维修的方便.
4.6安装时,应将阀门内腔清洗干净,防止污垢卡阻或异物损伤密封部件.并检查各部件连接螺栓是否均匀紧固.
4.7运行中应经常检查与介质接触的部件,并按实际使用情况或运行周期,定期更换密封圈.（密封圈橡胶老化时间一般二年左右）
4.8 正常使用的执行机构平时要进行适当的维护.进入汽缸的压缩空气必须经过过滤器.要定期观察油雾器的油位,油位降低要及时加油,以保证润滑油不断地进入汽缸,对汽缸内的运动部件进行良好的润滑.在整个供气系统的始端应设置排水装置,并定期将压缩空气中的水分排尽,以保证压缩空气干燥.
4.9 如应用于间断性的管路上,则在停用期间,应清洗与介质接触部位,以延长阀门的使用寿命.
4.10 经检修后的阀门,在应用前需按有关测试规定进行密封性试验,合格后方能安装使用.并做好维修记录以备查考.
