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! Thank you for your attention to the Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd website (http://ceshi5.66554433.cn)!

  知道伸缩器在管道中发挥着什么作用吗?

  伸缩器按材质分为:钢制伸缩器、橡胶伸缩器、不锈钢伸缩器。伸缩器在一定范围内可轴向伸缩,也能在一定的角度内克服管道对接不同轴向而产生的偏移,能很 大的方便阀门管道的安装与拆卸,在管道允许伸缩量中可以自由伸缩,一旦越过其*伸缩量就起到限位,确保管道的*运行。

  伸缩器又称之为伸缩节、伸缩接头、补偿接头、补偿器、套管伸缩器、套筒伸缩器、柔性伸缩器、热力伸缩器和滤网伸缩器,按其材质分为碳钢伸缩器、灰铸铁伸缩器、球墨铸铁伸缩器、橡胶伸缩器和不锈钢伸缩器。

  主要为保障管道*运行,具有以下作用:补偿吸收管道轴向、横向、角向热变形;吸收设备振动,减少设备振动对管道的影响;吸收地震、地陷对管道的变形量。该产品为各种给排水管道、水塔、水泵、水表、阀门的安装拆换提供了很 大方便,给长距离管路因温差伸缩起到了很好的调节作用。

  该产品管材大体分为两种:金属型和橡胶型,金属型又分铸铁、镀锌和钢制三种。工作压力分 PN6 、 PN10 、 PN16 三种,安装前须松开压盘螺栓,将该产品拉至安装长度,然后用对角法拧紧,切勿压偏,如架空使用,两端需放置支墩,法兰连兰采用 GB4216.3 - 4126.5 标准。
