Common pressure-relief devices are a pressure-relief valve for primary protection and a rupture disc for secondary protection.
常用的减压装置是一个作为主要保护的减压阀和一个作为二级保护的破裂盘。Built-in pressure relief valve to protect the unit against any abuse from strong pressure or strong wind when closing the door.
内置减压阀，防止因外来强压或强风状态下闭门而造成地弹簧损坏或漏油。sec The PORV (pressure relief valve) opens automatically, releasing steam into a holding tank.
秒减压阀自动打开，将蒸汽释入一个储存罐。Built-in relieve value, prevent damaging the main unit and oil leakage caused by shutting the door by strong pressure or wind.
内置减压阀，防止因外来强压或强风状态下闭门而造成的主机损坏或漏油。Otherwise deal with air filter relief-pressure valve for routine maintenance, ensure that the air dry, no pollution.
否则应对空气过滤减压阀进行日常维护保养，确保输入空气干燥、无油污。The performance test of reduced pressure valve and the length-of-life test system were developed.
研制了减压阀的全自动性能与寿命试验系统。Hydraulic fluid power - Pressure-reducing valves, sequence valves, unloading valves, throttle valves and check valves - Mounting surfaces.
液压传动.减压阀、顺序阀、卸载阀、节流阀和止回阀.装配面In a modulating period T as to an ideal decompression valve voltage wave is complete the same as the displacement wave of valve core.
对一理想的减压阀在一个调制周期T内，电压波形与阀芯位移波形完全相同。The PORV light goes out, indicating that the valve is now closed. The valve is actually still open.
减压阀指示灯熄灭，表明阀门当前已关闭。阀门事实上还开着。
