最新的HP组件包内含优质的美国瓦茨部件，包括：新型AS-B青铜导气罩和B911S青铜进水阀和防倒流装置组合件。

This paper analyzed the application case of the components such as anti-backflow equipment or air-pressure tank that using in the pipe network add-pressure water supply equipment.

本文对管网叠压供水设备中的倒流防止器和气压罐等器件的应用情况进行分析。

As the name suggests, its role is to prevent the media back.

顾名思义，它的作用是阻止介质倒流。

Check valves are automatic valves that open with forward flow and close with reverse flow.

止回阀是一种自动化运行的阀门，这种阀门当流体向前流动时处于开启状态，而当流体倒流时则处于关闭状态。

At this point reverse flow may allow process products to backflow into the cylinder.

在这一点倒流会允许过程中的产品回流进钢瓶。

The refluence of Chuangjiang River can be partly proved by the provenance of its higher terraces. The refluence had possibly occurred if the sediment originate form east but not west.

川江倒流的问题可以利用川江高阶地的物质来源进行佐证，如果川江上段高阶地的物质来源于东部而不是西部，则川江就有倒流的可能性。

Results: The findings were classified into 5 categories: posterior nasal drip (60.7%), glottic lesion (60.7%), oropharyngeal mass (13.1%), suspected laryngopharyngeal acid reflux (13.1%), and laryngeal neoplasm (0.7%). GL and PND both predominated in the only-1-category group (51.0%), PND+GL in the combined-2-category group (42.1%), and PND+GL+OPM in the combined-3-category group (4.1%).

仅1种病灶者(51.0%)以声门病灶或鼻涕倒流为多，合并2种病灶者(42.1%)以鼻涕倒流合并声门病灶最多，合并3种病灶者(4.1%)以鼻涕倒流合并声门病灶及口咽肿块最多；少数(2.8%)无任何发现。

The approach to non-bacterial prostatitis and prostatodynia is several fold depending on what is believed to be the cause of the problem.

如果医生觉得是因为尿液倒流到膀胱，再进入前列腺，那么就要用减少尿液倒流的药物。

As a downstream piping system when the valve opens, reflux valve, when closed, the main medium used to prevent backflow to prevent the pump and drive motor reversal, as well as a container medium discharge; currently the most commonly used is the valve flap around the body Swing Pin rotation flap valve and the valve body along the vertical axis to move lift check valve, but the above two kinds of structures exist in the valve closed, medium speed back quickly from the largest drop to zero, inlet side of the pipe resulted in the rapid pressure rise, resulting Proportional Pressure Reducing Valves in damaging effects on the piping system of water hammer phenomenon, it is generally a diameter of valve production of 50 ~ 500 mm.

止回阀作为管道系统顺流时开启，逆流时关闭的阀门，主要用于防止介质倒流，防止泵及驱动电机反转以及容器内介质泄放；目前使用最普遍的是阀瓣围绕阀体销轴旋转的旋启式止回阀和阀瓣沿着阀体垂直中心线移动的升降式止回阀，但以上2种结构的阀门均存在关闭时介质倒流速度从最大迅速降为零，致使管道进水管一侧内压迅速升高，从而产生对管路系统有破坏作用的水锤现象，所以一般止回阀生产口径为50～500 mm。

The averaged gas velocity of flowing backward between the exhausting duct and the mixture tube increases with the rise of the main nozzle flux and the downwash flow velocity.

实验发现外套出口和混合管之间夹层存在气流倒流现象，倒流平均速度随着主喷管流量和下洗气流速度增加而增加。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
