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!

橡胶防震接头在消防水泵进出口安装方法

Time：2019/2/27 9:36:12
橡胶防震接头又称橡胶软接头，橡胶软连接，橡胶伸缩节，橡胶伸缩器，橡胶补偿器，橡胶膨胀节。柔性橡胶防震接头主要安装在水泵进出口处，有效的吸收水泵的震动和噪音，大大的保证了水泵的使用寿命和噪音的减小，有效的保证了安静的生活环境。
橡胶防震接头伸缩器在闸阀前后都行，其作用一是减震、二是热涨冷缩的需要、三是方便拆装阀门及维修需要；止回阀只要在水泵之后的扬水管上就行，其作用是保护水泵，一般装在闸阀之后。
止回阀设在水泵前不知有什么太大意义实在想不出。实际的安装顺序应该是：橡胶软连接，止回阀，闸阀。压力表装在水泵出水口上，但一定要在止回阀前。橡胶防震接头是为了起减振。当然是水泵与管路系统的连接处。
正常工作时，闸阀是不太操作的，而止回阀是频繁动作的，所以维修概率较大，维修时关闭该泵出水管闸阀就能维修而不影响系统的正常运行。
压力表装在止回阀前，可以防止水锤作用对压力表的冲击和破坏。有人提出大口径管，止回阀装在闸阀后以便开闭，这不现实。因为水泵停止时由于止回阀存在，装在止回阀后的闸阀前后的水压是一致的，闸阀的开闭是不存在问题的，当然大口径阀门本身就比较难操作一点的。
