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)!

 套筒补偿器有哪些特点?下面就和小编来了解一下吧。

  1.双向套筒补偿器,在普通型的外套管两个方向都有均有伸缩芯管,补偿粮食普通型的两倍,并且用于双向补偿,减少了采用两个普通型的长度尺寸和成本。

  2.直埋式套筒补偿器,采用先进密封结构和密封材料,适用于热水、蒸气、油脂类介质,通过滑动套筒对外套筒的滑移运动,达到热膨胀的补偿。具有结构合理、*可靠、使用寿命长、不渗漏、安装维修方便、适用范围广等特点。同时,便于管路设计,便于安装施工,可减少固定支架的设置。

  3.双密封波纹套筒补偿器(专利产品), 具有双保险作用。本产品将波纹管式补偿器融为一体,即当于在波纹管补偿器的外面增加了一道机械密封,波纹管一旦出现问题,补偿器仍能正常工作。性能可靠、提高抗弯能力。由于啬了机械密封,使在波纹管内部的波纹管与外界隔离,不受外界有害物质尤其是氯离子的侵害使波纹管补偿器的工作更为可靠,同时机械密封增加了活动端的导向作用,提高抗弯能力。

  4.一次性套筒补偿器,用于直埋管道预热膨胀后在管道两接触面处焊死,外套管和芯管不能再做相对移动,然后填埋,具有和管道同寿命的特点。

  5.机械密封式套筒补偿器,是由至少一对垂直于旋转轴的端面,在流体压力和补偿机构外弹力的作用下,与另一端面保持贴合并相对滑动,而构成防止流体泄露的装置。其特点是形位公差和配合精度要求较高,无泄露,避免了以往旧式补偿器由于泄漏而造成的频繁损坏。

  6.填料密封式套筒补偿器,是一种接触式密封,在外套管与芯管之间填入弹性密封材料,在填料受到轴向力压紧后能紧贴在芯管表面,利用密封材料的弹性变形补偿密封面的磨损,阻止介质外漏,目前由单一填料发展成组合使用,如硬填料放在深部,软填料在压盖附近;或硬软填料中间放入密封油,出现泄漏时,采用补注油的方法止漏。
