安全阀

We suggest the use of a model DET expansion tank, the Watts Governor 80 ball cock and thermal expansion relief valve, or a 530C calibrated pressure relief valve.

我们建议采用型号DET膨胀罐，美国瓦茨Governor 80球旋塞阀和热膨胀安全阀，或者一个型号530C有刻度压力安全阀。

We suggest the use of a model DET expansion tank, the Watts Governor 80 ball cock with integral thermal expansion relief valve, or a 530C calibrated pressure relief valve.

我们建议采用型号DET膨胀罐，美国瓦茨Governor 80球形旋塞带整体热膨胀安全阀，或一个530C刻度压力安全阀。

While relatively few (less than 1%) of the relief valves in the BP refineries have rupture disks under them, the instances in which vessels have the rupture disk/relief valve combination are nevertheless important because of the potential consequences of a failed pressure relief system.

因为卸压系统出现问题会导致潜在危险，所以爆破片和安全阀的结合使用是相当重要的，然而在BP炼厂安全阀下有爆破片是非常少见的（少于1%）。

For this design strategy to work properly (i.e., the rupture disk protecting the relief valve until the pressure reaches the disk's bursting point), the rupture disk must not leak or fail prior to the system pressure increase.

这样的设计能够很好的工作，前提是爆破片在系统压力增大之前不能泄露或者损坏（也就是说，在压力到达爆破片的爆破点之前，爆破片起到保护安全阀的作用），正常情况下，在爆破片爆破前，爆破片和安全阀之间处在大气压力下。

If pressure relief valve continues to drip water, even at reduced pressure, flush relief valve by quickly raising lever several times.

如果压力安全阀还是再滴水，即使压力降低后还是滴水，则快速提升手柄几次冲洗安全阀。

The tank is equipped multiplex safety devices and instruments: Imported combination of pressure gauge and liquid level meter, interlayer equipped with outer cylinder explosion-proof device, the inner barrel equipped with combined safety system (combination system of double safety valve bursting diaphragm), discharge outlet of the safety valve and air valve adopting centralized collecting piping and discharging through the fire barrier

罐体设置有多重安全装置和仪表：配置进口压力表液位计组合，夹层设有外筒防爆装置，内筒设有组合安全系统（双安全阀爆破膜组合系统），安全阀和放气阀的排放口采用集中回收管道通过阻火器进行排放

Lever-type safety valve lever to rely mainly on the weight of the work force, but the lever-type safety valve size often limit the choice of scope.

杠杆式安全阀主要依靠杠杆重锤的作用力而工作，但由于杠杆式安全阀体积庞大往往限制了选用范围。

Safety valve for manual should be regularly put on gas or Other pumps drainage experiment; lever-type safety valve lever is stuck or the hammer is moved.

应定期对安全阀作手动放气或放水试验；杠杆式安全阀的杠杆被卡住或重锤被移动。

Lever-type safety valve lever hammer mainly depend on the force and work, but because of the huge Closed Spring Loaded Full Bore Type-High Pressure Safety Valve volume of leveraged safety valve is often limited range of choice.

杠杆式安全阀主要依靠杠杆重锤的作用力而工作，但由于杠杆式安全阀体积庞大往往限制了选用范围。

The locating pin in the relief valve cover should be aligned with the corresponding locating notch in the top of the relief valve body.

安全阀阀盖内的定位销钉应该对齐在安全阀阀体顶部相关的定位槽上。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
