安全阀门知识：阀门专业术语

阀门的定义：
“阀”的定义是在流体系统中，用来控制流体的方向、压力、流量的装置。阀门是使配管和设备内的介质（液体、气体、粉末）流动或停止、并能控制其流量的装置。
二 根据启闭阀门的作用不同，阀门的分类方法很多，这里介绍下列几种。
1. 按作用和用途分类  重庆阀门 重庆安全阀
(1) 截断阀：截断阀又称闭路阀，其作用是接通或截断管路中的介质。截断阀类包括闸阀、截止阀、旋塞阀、球阀、蝶阀和隔膜等。
(2) 止回阀：止回阀又称单向阀或逆止阀，其作用是防止管路中的介质倒流。水泵吸水关的底阀也属于止回阀类。
(3) 安全阀：安全阀类的作用是防止管路或装置中的介质压力超过规定数值，从而达到安全保护的目的。
(4) 调节阀：调节阀类包括调节阀、节流阀和减压阀，其作用是调节介质的压力、流量等叁数。
(5) 分流阀：分流阀类包括各种分配阀和疏水阀等，其作用是分配、分离或混合管路中的介质。
2. 按公称压力分类
(1) 真空阀：指工作压力低于标准大气压的阀门。
(2) 低压阀：指公称压力PN ≤1.6Mpa 的阀门。
(3) 中压阀：指公称压力PN 为2.5、4.0、6.4Mpa的阀门。
(4) 高压阀：指工称压力PN 为10～80Mpa的阀门。
(5) 超高压阀：指公称压力 PN≥100Mpa的阀门。
3. 按工作温度分类
(1) 超低温阀：用于介质工作温度 t<－100℃的阀门。
(2) 低温阀：用于介质工作温度－100℃≤t≤－40℃的阀门。
(3) 常温阀：用于介质工作温度－40℃≤t≤120℃的阀门。
(4) 中温阀：用于介质工作温度120℃
(5) 高温阀：用于介质工作温度t>450℃的阀门。
4. 按驱动方式分类
(1) 自动阀是指不需要外力驱动，而是依靠介质自身的能量来使阀门动作的阀门。如安全阀、减压阀、疏水阀、止回阀、自动调节阀等。
(2) 动力驱动阀：动力驱动阀可以利用各种动力源进行驱动。
电动阀：借助电力驱动的阀门。
气动阀：借助压缩空气驱动的阀门。
液动阀：借助油等液体压力驱动的阀门。
此外还有以上几种驱动方式的组合，如气-电动阀等。
(3) 手动阀：手动阀借助手轮、手柄、杠杆、链轮，由人力来操纵阀门动作。当阀门启闭力矩较大时，可在手轮和阀杆之间设置此轮或蜗轮减速器。必要时，也可以利用万向接头及传动轴进行远距离操作。
综上所述，阀门分类方法是很多的，但主要是按其在管路中所起的作用进行分类。工业和民用工程中的通用阀门可分成11类，即闸阀、截止阀、旋塞阀、球阀、蝶阀、 隔 膜阀、止回阀、节流阀、安全阀、减压阀和疏水阀。其他特殊阀门，如仪表用阀、液压控制管路系统用阀，各种化工机械设备本体用阀等，均不在本书介绍范围以内。
5. 按公称通径分类
(1)小通径阀门：公称通径DN≤40mm的阀门。
(2)中通径阀门：公称通径DN为50～300mm的阀门。
(3)大通径阀门：公称阀门DN为350～1200mm的阀门。
(4)特大通径阀门：公称通径DN≥1400mm的阀门。
6. 按结构特征分类
(1)截门形：启闭件(阀瓣)由阀杆带动沿着阀座中心线作升降运动；
(2)旋塞形：启闭件(闸阀)由阀杆带动沿着垂直于阀座中心线作升降运动；
(3)旋塞阀：启闭件(锥塞或球) 围绕自身中心线旋转；
(4)旋启阀：启闭件(阀瓣) 围绕座外的轴旋转；
(5)蝶行：启闭件(圆盘) 围绕阀座内的固定轴旋转；
(6)滑阀行：启闭件在垂直于通道的方向滑动。
7. 按连接方法分类
(1)螺纹连接阀门：阀体带有内螺纹或外螺纹，与管道螺纹连接。
(2)法兰连接阀门：阀体带有法兰，与管道法兰连接。
(3)焊接连接阀门：阀体带有焊接坡口，与管道焊接连接。
(4)卡箍连接阀门：阀体带有夹口，与管道夹箍连接。
(5)卡套连接阀门：与管道采用卡套连接。
(6)对夹连接阀门：用螺栓直接将阀门及两头管道穿夹在一起的连接形式。
8. 按阀体材料分类
(1)金属材料阀门：其阀体等零件由金属材料制成。如铸铁阀、碳钢阀、合金钢阀、铜合金阀、铝合金阀、铅合金阀、钛合金阀、蒙乃尔合金阀等。
(2)非金属材料阀门：其阀体等零件由非金属材料制成。如塑料阀、陶 阀、搪 阀、玻璃钢阀等。 重庆阀门 重庆安全阀
(3)金属阀体衬里阀门：阀体外形为金属，内部凡与介质接触的主要表面均为衬里，如衬胶阀、 衬塑料阀、衬陶阀等。阀门专业术语见下页：
