Separation of water and gas is reliable (water vapor enters from bottom of valve by the U general type), remain the state of water sealing in the valve, effectively prevent leakage of steam.
汽水分离可靠（水汽经U型普通从阀底部进入），阀内始终处于水封状态，有效阻止蒸汽泄漏。

And the influence of main inherent and exterior factors on dynamic leakage of vapor space was analyzed.
分析了制冷剂主要内外因素对气相空间动态泄漏过程的影响。

Though there is no condensate water that uses ball-type sealed lever to make the valve clack tightly adhesion to the valve seat, it can prevent the fresh vapor from leakage.
