Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice. It will be hot in about twenty or thirty days. After the summer solstice, the ground is strongly heated and the air convection is vigorous, and thunderstorms often form from afternoon to evening. ZhongYuan remind you Construction of chemical and municipal pipelines in power plants industry customer friends: the weather is hot, pay attention to heatstroke prevention!

  伸缩接头购买需要注意哪几方面?

  1、综合考虑各种因素确定合理的安装位置

  一般情况下管道伸缩接头是伴随着阀门、止回阀一起使用的。有些样木在安装使用注意事项中只注明:伸缩器安装在阀门和止回阀后。仅有这条说明还远远不够。设计时除考虑满足正常操作要求外,还应考虑满足检修要求。

  特别是在检修设备、阀门时,阀门之后的管路中仍有压力存在。此时,设计时按介质流向将伸缩接头安装在阀门之后,同时应考虑在伸缩器之后的管路上设置一个用于检修的阀门;对于不经常检修的情况,从*、经济角度出发,可对伸缩接头进行改造,设置限位装置。

  2、根据管道中介质、压力、管路伸缩量及安装时需调节的角度,选择相应材质、压力等级及连接方式的伸缩器。
