查询词典 vent

Especially for the fluid containing sand, cutting may damage the sealing surface 5, soft sealing gate valve of the operating temperature limits by the valve seal material good throttle control when needed (such as control valves or bypass pipe had a small vent), the cut-off valve is the most appropriate valve.

Especially for the fluid containing sand, cutting may damage the sealing surface 5, soft sealing gate valve of the operating temperature limits by sealing material Valve When the need for good throttle Cast Gate, Globe, Check Valves control (such as control valves or bypass pipe had a small vent), the stop valve is the most appropriate Ball When the operating temperature between-29oC to 200oC, most manual valve suitable for hydrocarbon and utility systems operations, the use of the ball at 100oC above, applications should be carefully considered when the temperature of the soft sealing material limit should be more than 100oC.

尤其对于含有砂的流体，旋塞阀节流会损坏密封表面5、软密封闸阀的操作温度受密封材料的限制截止阀当需要好的节流控制（如控制阀的旁通管路或有小的排气孔）时，截止阀是最合适的球阀当操作温度在-29oC至200oC之间时，大部分手动球阀适应于烃及公用系统的作业中，在100oC以上使用的球阀，应用时要仔细考虑软密封材料的温度限制应该在100oC以上。

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。

The frame is dome-shaped above the vent opening, to force noise reflection off the dome-shaped frame.

Moreover, this article offers various improvement programs for smoke evacuation system in subways system. Initially, we offer an idea to minimize the anti-smoke divisions and to rearrange vent positions to resolve the failure of station smoke evacuation mode. In the study of smoke evacuation process at tunnel track area, we find an upward slope will block smoke evacuation. This study also finds that start of fans operation will speed up the accumulation of smoke and endanger people's life during escape. The way to resolve is that we need to add fans at upward slope. This result is different from the report of one dimensional SES simulate analysis. To timely correct the safety evaluation result in SES report and to efficiently improve the failure of smoke evacuation system design are recommended by this article. Therefore, an increase of time for people to escape in fire hazard with less casualty.

本文另於对捷运排烟系统提出各项改善方案中，初步提出车站排烟系统防烟区划缩小构想，并配合风口位置调整策略来解决失效的车站排烟模式；而隧道轨道区排烟系统在研究过程发现爬坡段有阻碍排烟效果，本研究发现风机开启后反而加速烟气滞留并危害人员逃生，解决之道则必需於爬坡段增加风机来排除，此与一维式SES模拟分析报告结果不同，故能藉以及时更正SES报告之安全评估结果，经由所提改善方案，有效改善所发现排烟系统设计之失效，提高人员火灾时逃生的安全时间，降低人员伤亡。
