Description
技术领域technical field
本发明属于城市供水管网安全技术领域，特别涉及一种爆管自动关闭阀门的技术。The invention belongs to the technical field of urban water supply network safety, in particular to a technology for automatically closing a valve when a pipe bursts.
背景技术Background technique
给水管网是重要的城市基础设施，其系统庞大、外部干扰因素多，且管道自身材料质量和安装质量差异较大。这使得给水管网爆管事故屡见不鲜。给水管网爆管事故不仅损坏给水设备，而且会导致大规模的淹水，影响生产和生活，冲断公路，影响公共交通，造成巨大的经济损失。而在自来水管发生之后，往往存在一个相当长时间的维修空窗区。因此我们设计了这款爆管水阀来解决这一问题。The water supply pipe network is an important urban infrastructure. Its system is huge, with many external interference factors, and the quality of the material and installation quality of the pipe itself varies greatly. This makes the pipe burst accidents of the water supply network common. A pipe burst accident in the water supply network not only damages the water supply equipment, but also causes large-scale flooding, affects production and life, breaks roads, affects public transportation, and causes huge economic losses. After the occurrence of water pipes, there is often a fairly long maintenance window. So we designed this squib water valve to solve this problem.
从国内外的研究现状来看，主要是针对自来水管网控制中心对于整个区域管网的检测方法，而对于自来水管爆管后紧急处置方法的研究还甚少。现在有很多研究自闭水阀的专利，大多也可以实现断水自闭的功能，但这些水阀往往存在着一些缺陷。其中最大的一个缺陷在于绝大多数的自闭阀在供水状态下是由水压顶开阀芯来实现使水阀开启的功能，这一设计最大的不足在于水压的大小常常不稳定，有时候会由于水压的波动引起阀芯的不断运动使水流不稳定，另外由于阀芯长期的运动会使弹簧失效，而引起水阀失效。如中国专利CN94230689所设计的自闭阀，就是使用了这种结构。Judging from the research status at home and abroad, it is mainly aimed at the detection method of the water pipe network control center for the entire regional pipe network, but there is still little research on the emergency treatment method after the water pipe burst. There are many patents on researching self-closing water valves, most of which can also realize the function of self-closing when water is cut off, but these water valves often have some defects. One of the biggest defects is that most of the self-closing valves open the valve core by water pressure to realize the function of opening the water valve under the water supply state. The biggest shortcoming of this design is that the water pressure is often unstable. Sometimes the constant movement of the spool will cause the water flow to be unstable due to fluctuations in water pressure. In addition, the long-term movement of the spool will cause the spring to fail, causing the water valve to fail. As the designed self-closing valve of Chinese patent CN94230689, this structure has been used exactly.
另外，一些自闭水阀的结构太过于复杂，如中国专利号CN201310701044，该发明在实现自闭的整个过程中使用了四个运动机构，而我们知道，机械的结构越是复杂，往往故障率越高。另外该发明在设计中存在着结构不易拆卸与装配的缺点，一点发生故障，将不易排出。In addition, the structure of some self-closing water valves is too complicated, such as Chinese Patent No. CN201310701044, which uses four motion mechanisms in the whole process of realizing self-closing, and we know that the more complicated the mechanical structure, the more often the failure rate higher. This invention exists the shortcoming that structure is not easy to disassemble and assemble in the design in addition, and one point breaks down, and will not be easy to discharge.
