汾河水库作为引黄工程南干联接段的近期调节水库，也存在泥沙淤积问题；随着汾河水库泥沙淤积的加剧，兴利库容将逐年减少并逐渐失去对引黄水的调节能力，需要在上游修建新的调节水库，在这种情况下，进行了万家寨引黄工程联接段调节水库泥沙冲淤分析研究，主要目的就是确定南干调节水库汛期运用方式、汾河水库、汾河二库、好水沟水库联合运用的淤积形态，以及汾河水库异重流排沙规律和汾河水库的运行调度方式。

When a sudden power failure or accident or normal pump stops when the pump stops, the valve inlet water velocity to reduce stress Agency, the valve plate also fall, when its velocity is zero (that is, inlet flow rate is zero Department), large valve plate because of its own gravity and rapidly turn off (time 3s ~ 5s), the majority of water to prevent backflow, when the valve before and after the formation of a water pressure, water stress, on the one hand through the small valve at the bottom of the three slot for pressure relief vent pressure. 4 water stress from the bypass tube into the cavity patch up the control room (this process for the suction pressure chamber that can effectively absorb the energy of water), when water stress on cavity than inferior vena cava, the pressure of water promote the diaphragm down mobile , the current cavity pressure of water being squeezed out all the small valve plate slowly drop back to standby status, the process time to ease closure adjustable (3s ~ 150s), then the valve has been fully closed, watertight.

当突然停电或事故停泵或正常停泵时，阀门进水口处压力水流速降低，大阀板也随之下降，当其流速为零时，大阀板由于自身重力而迅速关闭（时间3s～5s），可防止大部分水倒流，此时阀门前后形成一种水压差，压力水一方面通过小阀板底部的三条泄压槽进行泄压。4）压力水从旁通管进入膜片控制室上腔（此过程为吸压腔，能有效吸收一部分水能量），当上腔压力水大于下腔时，压力水推动膜片往下移动，当下腔压力水全部被挤出来时，小阀板缓缓下降，恢复到待机状态，此过程中缓闭时间可调节（3s～150s），届时阀板已全部关闭，滴水不漏。

A safety level-based evacuation scheme of subway station is presented in this paper, with performance-based evacuation design combined. According to the evacuation characteristics of subway station, accidental evacuation time and available safety evacuation time under smoke control have been classified into three safety levels respectively.
