When tank pressures are 90 percent or more of set pressure, seat leakage is common.
当罐压力为设定压力的90%或更高是, 阀座的泄露很常见.

The closer a tank gets to the set pressure, the more the seats leak.
越是接近罐的设定压力, 泄露越严重.

A direct - acting vent valve is tightest when tank pressures are percent or less of set pressure.
当罐压力为设定压力的75%或更低时,直接作用式通气阀有最好的气密性.
