阀门的种类和术语及零配件等中英文对照表
一.闸阀
又称闸板阀，闸阀是利用闸板来控制启闭的阀门，启闭件由阀杆带动沿阀座密封面做升降的阀门，闸阀阀杆结构分明杆和暗杆两大类，按连接方式分螺旋连接和法兰连接两种
二.截止阀
又称气门是启闭件由阀杆带动，沿阀座轴线作升降运动的阀门，根据连接方式不同分为螺纹连接和法兰连接两种，截止阀是有方向性的，安装时必须注意，介质流动方向是由下向上流过阀盘，在阀体外标有箭头，在安装时习惯称为低进高出，
三.止回阀
又称逆止阀或单向阀，其阀是启闭件借助介质作用力，自动阻止介质倒流的阀门，止回阀门分为升降式和旋启式两大类。
四.旋塞阀
是指启闭件绕其轴线旋转的阀门，旋塞阀是一种老式阀门，也叫旋塞，考克，转心门
五.球阀
是在旋塞阀的基础上发展起来的阀门，启闭件是个球体，绕球体的垂直中心线旋转90度，即可使球阀开启或关闭
六.蝶阀
蝶阀的启闭件是碟板，可以围绕阀座内的固定旋转90，以实现其开启式关闭
七.节流阀
是指通过启闭件改变通路截面积，以调节流量，压力的阀门，过去也叫针型阀
