The utility model can effectively clear the blockage of the siphon tube of the closet, and has the advantages of simple structure, convenient installation and low cost. 本实用新型可以有效的清理马桶虹吸管的堵塞,具有结构简单,安装方便,成本低的优点。
It is not necessary to set air hole at the inverted siphon tube mouth and also no need to have the top of the tube entrance lower than the water level of the minimum for the tube. 倒虹吸管进口不需要设置通气孔,也没必要使倒虹吸进口顶缘低于倒虹吸管通过最小流量时进水口前的水位。
The research achievement has certain value for extension in design and practice of inverted siphon tube with low head and large discharge in plain areas and in the middle line project of water diversion from the Yangtze River into the Yellow River. 该项研究成果在南水北调中线工程和平原地区低水头大流量倒虹吸管的设计与运用中有一定的推广价值。
Discussion on the Conditions Suitable for Exhaust Device of Siphon Tube 虹吸管排气设备适用条件探讨
The part of tube prescribes the throttle character and the pressure regulation principal of the valve, and calculating press lose of straight tube, siphon and cross tube. 详细分析了阀门的节流特性与调压原理,以及直管、弯管、三通的压力损失计算方法;
The reason why the automatic exhaust valve failed to be used for air exhaust from siphon tube was investigated. 对自动排气阀不能用于虹吸管排气的理由进行了分析。
The feasibility was discussed for the use of Venturi tube and automatic exhaust valve for expelling air from siphon tube. 探讨了虹吸管利用文氏管及自动排气阀排气的可行性。
The siphon discharge passage, straight outlet tube and bell-like outlet passage physical model were designed and made, three outlet passage hydraulic loss were measured and compared. 3. 对常见的虹吸式、直管式和钟形出水流道,设计并制作物理模型,测试并比较其水力损失。
