这一个是很熟悉的，增压安全阀的疏忽打开，或者是在压水式反应堆的减压阀，或者是在沸水式反应堆的安全阀。
This one is the familiar one, inadvertent opening of a pressurised safety or relief valve in a PWR or a safety valve in a BWR.
工程师打开安全阀让蒸气外逸以便降低压力。
The engineer opened the safety valve to allow the steam to escape and so reduce the pressure.
高粘度泵的出口管路上还应当设置安全阀等保护装置，这样一旦泵的出口通道发生堵塞，就可以打开安全阀卸压。
High viscosity of the pump outlet pipe also shall set up relief valve or other protective device on the road, so that once the clogging pump export channels, can open the relief valve pressure relief.
高粘度泵可配安全阀，当泵或管路系统超压时，安全阀门打开，形成内部回流，保证系统安全。
High viscosity pump can match the relief valve, when the pump and piping system overpressure, safety valve is opened, the formation of internal reflux, ensure the safety of the system.
