一、复习巩固
上节课我们学习了管道的布置与安装，主要介绍了管道布置的一般要求以及安装的一般要求。
二、导入新课
说道阀门这个词，大家一定不会陌生，我们在日常生活中要经常与它打交道。那么，我先问同学们一个问题，日常生活中我们遇到的阀门有哪些？（提问）本节课就为大家介绍阀门的概念、常用阀门的结构及特点。
三、学习新课
1、阀门的概念
阀门是流体输送系统中的控制部件，具有截断、调节、防止逆流、稳压、分流等功能。
对几种功能结合生活生产进行举例说明。
2、常见的六种阀门
闸阀、截止阀、蝶阀、旋塞阀、球阀、止回阀。
3、截止阀、止回阀的结构及特点
截止阀：
原理：利用阀杆升降带动阀盘，改变阀盘与阀座间的距离达到控制阀门的启闭。
特点：结构复杂，操作简便、易于调节流量和截断通道，启闭缓慢无水锤现象。
适用场合：水、蒸汽、压缩空气等管路，但不能用于粘度大、易结焦、含悬浮和结晶颗粒料的介质管路。
通过图片说明截止阀安装时应“低进高出”
为什么“低进高出”？如果高进低出在关闭状态，阀杆就浸没在介质中容易被腐蚀。
止回阀
原理：利用阀前后介质压差而自动启闭。
特点：结构简单，无需驱动装置。
适用场合：用于泵和压缩机的管路、疏水器的排水管以及其他不允许介质作反向流动的管路。
止回阀分类：升降式、旋启式
通过外观图、工作原理图对止回阀结构进行讲述。
四、课堂小结
1、阀门的概念
2、常用的六种阀门：
闸阀、截止阀、蝶阀、旋塞阀、球阀、止回阀
3、截止阀：安装具有方向性，“低进高出”
止回阀：无需驱动装置
五、布置作业
1、截止阀安装时应注意什么？
2、止回阀有什么特点？
