阀门应具有结构坚固、控制精度高、泄漏量为零、摩擦力矩小、运行灵活、噪音低等特点。阀门应满足不同安装条件的需要，均可立式或水平安装，应能适用于清水和污水等介质，结构应保证在以污水为介质的条件下，不易造成堵塞和无法操作的情况。</p>]]></description><category>行业资讯</category><comments>http://www.valvesealing.com/News/geipaishuifamen.html#comment</comments><wfw:comment>http://www.valvesealing.com/</wfw:comment><wfw:commentRss>http://www.valvesealing.com/feed.asp?cmt=82</wfw:commentRss><trackback:ping>http://www.valvesealing.com/cmd.asp?act=tb&amp;id=82&amp;key=c18d4e9c</trackback:ping></item><item><title>垫圈弹簧延长阀门填料寿命</title><author>China@ValveSealing.com
