valve fouling meaning in Chinese
气门结污
Examples
- Watts air gap drains are designed to collect water that is being discharged by the relief valve , due to minor check valve fouling and / or line pressure fluctuations
美国瓦茨气隙排放装置适用于收集由于第二止回阀污染和/或管道压力波动而从安全阀排放出来的水。 - Therefore , if both check valves foul , and simultaneous negative supply and positive backpressure develops , the relief valve uses the air - in / water - out principle to stop potential backflow
因此，如果两个止回阀都受到污染，并且同时出现负供应压力和正反压力，则这种安全阀就利用气进/水出原理来阻止潜在的回流。
