The role of intake tower is very important in the hydro - junction . the stability of intake tower and access ramp plays a key role in the failure - free operation of the hydro - junction 进水塔在整个枢纽中起着极其重要的地位，它和进水口边坡的稳定安全与否将对整个枢纽的正常运行起关键作用。
By the scale of 1 : 35 flood - relief model test , combined the structures built and the pump entrance will be built of baishan dam , to decide the overall arrangement of the water cushion 通过1 ： 35比尺的整体泄洪模型试验，结合白山已建的建筑物及筹建的白山大泵进水口，选定水垫塘的总体布置方案。
During use , if water is insufficient , you can turn off the tap , screw off the water inlet hose of controller , use water to clean the inside filter , and then reinstall it 在使用过程中，若出现水量不足时，可把水源关掉，拧开控制器进水口的软管，用水小心清洗进水口内的过滤网，再重新装好即可。
Taking practical situation of this project and much engineering experience into account , the scheme with axle golden section elliptical arc surface is proposed through comparing nine optimization schemes with model test 结合工程实际和以往经验，比较了9种进水口曲线型式的试验结果，确定了长短轴黄金分割比的椭圆弧面的方案。
On the heavy silt - laden rivers , desilting at the water intake of hydropower station is a problem widely concerned not only for the large reservoir with high dam and high water head , but also for the runoff river hydropower station with lower water head 摘要在多沙河流上，无论是高坝大库的高水头电站，还是低水头河床式枢纽，电站进水口的取水排沙历来是一个倍受关注的问题。
The sediment model tests for the desilting bottom intakes of two hydropower stations are introduced herein , in which a new combined type of " grid desilting gallery + desilting bottom intake " ( grid desilting bottom intake ) is put forward 文中介绍了2个电站进水口排沙底孔的泥沙模型试验情况，提出了一种新的“格栅式排沙廊道排沙底孔”的组合型式（简称格栅式排沙底孔） ，取得了理想的排沙效果，较好地解决了工程实际问题。
Based upon the present regulation , the design and construction check and structure strength check , the electric power generation water inlet anchor gate crane platform ' s hydro - engineering structure of fushui power plant were conducted and an analysis for the reasons of building structure fracture was carried out 摘要进行了富水电厂发电进水口闸门启闭机平台安全检测，依据现行规?对其建筑物进行了设计与施工复核、结构的强度复核和建筑物的裂缝成因分析。
This model of electromagnetic valve has the single - way check function and a patent design of block - up resisting and is the ideal self control valve for the water supply system with a high level container or tank or the automatic water supply system with a high level container or tank or the automatic water supply facility required the function of adverse current prevention . the amalgamation inflicts to hike in the inflexions of can percolation function that purge Fcd . 3 148f ：进水口与出水口均为4分15外螺纹铜接头该型电磁阀具有单向止回功能，专利防阻塞设计，是高水位容箱器供水系统或其他兼需防逆流功能的自动供水设备的理想自控阀门;并增加了过滤装置。
This model of valve overcomes such defects with the motor valve , piston - type electromagnetic valve as the post - wear defective closure due to the mechanical movement , the soft membrane full of elasticity , the balance hole can not close water because the foreign matters and mud sand accumulate and block it up etc . , the highly effective use of the unique circuit greatly raises the reliability of the switch , extensively used for ic card watermeter , infrared induced sanitary utensils , etc Fck - 118 ：进水口出水口为1寸25内螺纹该型阀克服了如电机阀活塞式电磁阀机械运动磨损后的关闭不良。软性膜片富有弹性，平衡小孔不会因杂质与泥沙的淤积堵塞使其关不住水，独特线圈磁路的高效利用大大提高了阀开关可靠性，广泛用于ic卡水表红外线感应洁具等自动控水系统。
Xh rubber slowly - closing cut - off vavle is a new water supply and drainage vavle with full rubber structure , duck - mouthed appearance and functions or positive flow - in and reserve cut - off . according to thrust analysis and calculation as well as different operation mechanism and different rubber products by special processing . all will be open at weak hydraulic pressure is higher , the vavle gate will open more greatly and the water flow is greater . at reserve operation , the vavle gate closes naturally and seals tightly cut - off vavle ; the back pressure is higher , the vavle gate closes more tightly and the seal effect is better . it is used widely in various drainage exit to prevent from pouring backwards and flowing backwards in city planning , water conservancy and sewage disposal etc . it is the ideal productto replace flap vavle Xf型橡胶缓闭逆止阀是一种全橡胶结构外形呈“鸭嘴状” ，具有“正向流入反向逆止”功能的新型给排水阀门产品。它根据受力分析和受力计算，针对不同的工况，采用不同的设计机理，选用不同的橡胶配方，并按特殊工艺制作而成。正向工作时，水由进水口流入，微小的水压，便能打开阀门，水压越大，阀门开启越大，水流量越大。
