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)!

区分传力接头不同的的填料

  传力接头所用的填料是一种热圈,它的用途是在扭紧法兰盘面的螺栓时,垫在盘间,可以填补法兰两盘面不均匀和凹入的部分。在温度不超过40℃时,用作垫圈的材料为橡皮麻布。在温度60℃时,可以用亚麻经线做成的橡皮麻布。在温度达到95℃时,垫圈的材料可以用灰纸柏。

  采用纸柏是因为它比橡皮麻布更加牢固,橡皮麻布会受蒸汽或水压力的侵蚀。在装填之前,垫圈要在干燥油(桐油)中浸润一下。由于这样,就可以促成填料的凝固。在管道温度超过100℃时,可采用石棉纸柏或蒸汽纸柏,因为这两种纸柏是*厚和*硬的一种纸柏,它在高温度下也具有保固性。

  蒸汽纸柏的成分中,包含有:石棉,橡胶,以及一些填充物(通常是白粉,白瓷土等。)在制造任何蒸汽纸柏时,都要通过机热的夹布机,并除去橡胶中的水分。石棉纸柏能够作为蒸汽暖气上法兰限位伸缩接头的垫圈,是因为它具有吸水性,不适宜在热水管道或凝结管道的法兰限位伸缩接头中应用。

  随着传力接头的出现,城市的供水和排水管道也随之变得更为稳定,古时候*早采用管道供水的就是古罗马,管道系统十分发达,不过受当时制造工艺和管道原材料的影响,当初的供水管道并不能深埋地下,所以供水管道也经常的被破坏,随着科技的创新突破,现在的原材料品质也是进行了大的调整,然后传力接头就把各个管道连接到了一起,从而巩固了管道之间的连接,但是传力接头在不同温度的管道中所用的填料也是不同的。
