额定工作压力英文

设计压力与相应的设计温度一起作为设计载荷条件，其值不得低于工作压力。公称压力是指管材在二级温度（20℃）时输水的工作压力。若水温在25℃-45℃之间应按不同的温度下降系数，修正工作压力。

公称压力大于或等于设计压力，设计压力=1.5×工作压力，工作压力由管网水力计算而得出；安全阀的公称压力表示安全阀在常温状态下的最高许用压力，高温设备用的安全阀应考虑高温下材料许用应力的降低。安全阀是按公称压力标准毓进行设计制造的。

设计压力的相关规定：

1、当容器上装有安全阀时：

考虑到安全阀开启动作的滞后，容器不能及时泄压，设计压力不得低于安全阀的开启压力[开启压力是指阀瓣在运行条件下开始升起，介质连续排出的瞬时压力，其值小于等于（1.05~1.1）倍容器的工作压力。

2、当容器上装有爆破片时：设计压力不得低于爆破片的爆破压力。其值可以根据爆破片的类型确定，取爆破片的设计爆破压力加上所选爆破片制造范围的上限，通常可取（1.15~1.3）倍最高工作压力。

3、当容器出口侧管线上装有安全阀时：其设计压力应不低于安全阀的开启压力加上容器至安全阀处的压力降。

4、当容器进口管线上装有安全阀：出口侧装有截止阀或其它截断装置时，其设计压力取以下两种情况之大者。

（1）安全阀的开启压力。

（2）按容器工作压力增加适当的裕度。

什么叫公称压力PN (MPa)？与管道系统部件耐压能力有关的参考数值，是指与管道元件的机械强度有关的设计给定压力。 公称压力一般用PN表示。（1）公称压力——制品在基准温度下的耐压强度，用PN表示，单位：M Pa 。（2）基准温度：材料不同，其基准温度也不同。如，钢的基准温度为250°C（3）公称压力1.0Mpa，记为：PN 1.0 Mpa2什么是工作压力？是指为了管道系统的运行安全，根据管道输送介质的各级最高工作温度所规定的最大压力。 工作压力一般用Pt表示。3什么设计压力？是指给水管道系统作用在管内壁上的最大瞬时压力。一般采用工作压力及残余水锤压力之和。 设计压力一般用Pe表示。4试验压力管道、容器或设备进行耐压强度和气密性试验规定所要达到的压力。 试验压力一般用Ps表示。5公称压力、工作压力、设计压力之间的关系公称压力是为了设计、制造和使用方便,而人为地规定的一种名义压力。这种名义上的压力的单位实际是压强，压力则是中文的俗称,单位是“Pa”而不是“N”。公称压力英文是nominal pres-surenomina:l in name or form butnot in reality(名义上的,有名无实的)。压力容器的公称压力指的是压力容器法兰的公称压力。压力容器法兰的公称压力一般分成7个等级,即0.25、0.60、1.00、1.60、2.50、4.00、6.40MPa。 设计压力=1.5×工作压力。工作压力由管网水力计算而得出。 1MPa ＝10bar （巴）＝ 10.2kg/cm2=100N/cm26关系试验压力＞公称压力＞设计压力＞工作压力设计压力=1.5×工作压力（通常）
