643.旅客氧气分配管道上压差电门测量压差的作用是什么? What is the function of differential pressure switch to measure differential pressure in the passenger oxygen distribution line?

　仅用于测量压差 Only used for measuring the differential pressure

　仅用于指示压差 Only used to indicate the differential

　用于当两根管道压差过大时,关掉漏氧一边 If two pipe pressure difference is too large, turn off the leakage side oxygen

正确答案：C

解析：

题目解析答案：C 解析：旅客氧气分配管道上的压差电门的作用是当两根管道的压差过大时，关闭漏氧一侧的供氧。这是为了确保氧气供应的均衡，以防止过多的氧气流向一侧，而另一侧氧气不足，从而保证旅客在紧急情况下都能获得足够的氧气。
