Separation of water and gas is reliable ( water vapor enters from bottom of valve by the u general type ) , remain the state of water sealing in the valve , effectively prevent leakage of steam 汽水分离可靠（水汽经u型普通从阀底部进入） ，阀内始终处于水封状态，有效阻止蒸汽泄漏。
The government has produced a guide and tv and radio apis on disinfection of households including bathroom cleansing and how to ensure the proper functioning of the water seal in u - shaped water traps 政府已制定指引、电视宣传短片及电台宣传声带，教育?民如何为家居消毒，包括如何清洁浴室和维持u形聚水器的隔气功用。
Note : when regulator is installed above the line or in a veritcal line on steam service , the control pipe must have a loop to form a water seal to prevent steam from contacting the diaphragm 注：在蒸汽应用中，如果调节阀安装在管道的上方或安装在垂直管道上，则控制管道必须有一个回路，以形成水密封，防止蒸汽接触隔膜。
When the water seal of the original online analytical instrument works , the sample gas mixes up , and carries dust and liquid , leading to the corrosion of the online instrument and affects its indication , so the analytical results are inaccurate or failures occur 摘要原在线分析仪表的水封工作时，存在样气串气、带尘、带液现象，造成在线分析仪器的腐蚀并影响仪表指示，致使分析结果不准确或出现故障。
With the action of the water pressure , the non - homogeneous deformation will emerge at the peripheral joint between the faceplate and the toe slab . under the circumstances of the high steep bank slope , the non - homogeneous deformation can damage the water seal and cause serious leakage 在高陡岸坡的情况下，面板堆石坝受水压力的作用，周边缝处的面板与趾板间要产生一定的不均匀变形，甚至使止水破坏，造成严重渗漏。
With the tectonic uplift of the source area and the climate turning dry , the coal forming period was over , the fluvial system and fluvial - delta system became to play a major role . based on the study of former researchers and the theory of deep basin gas reservoir forming , the deep basin gas trap in the ordos basin is analyzed and is supposed to form in the ramp of the basin . it is supposed that the hydrocarbon of the deep basin gas trap is mainly composed of coal , carbonate and carbonaceous shale and with the " upper water seal " in the north of the study area the g 根据深盆气成藏理论和前人的研究成果，分析了深盆气藏的分布类型，认为鄂尔多斯盆地深盆气藏属于盆地斜坡成藏类型；认为深盆气的源岩以煤、炭质泥岩、暗色泥岩和碳酸盐岩为主；北部气水倒置、东部露头区有天然气逸出；气藏具有多重压力系统；成藏机理主要是气体动态的运移与聚集，稳定的构造背景有利于气藏的大面积保存。
