Description

耐磨抗冲击球形补偿器 技术领域
本实用新型涉及一种耐磨抗冲击球形补偿器。
背景技术
电力、石油、化工、热力等行业的管道中一般都需要安装使用补偿装置，现有的补偿装置通常包括球形补偿器、波纹补偿器、旋转补偿器、套筒补偿器等，用于补偿管道轴向和径向的位移。球形补偿器由于具有结构相对简单、承压高、安全性能好、且可大转角旋转补偿的优点，因此得到了较多的应用。
申请人经研究发现，由于球形补偿器安装在管道中后需长期的运行，最长运行时间可达30年。在长期的使用过程中，球形补偿器的外套管与球体之间密封填料在所输送介质的长期冲击下也会产生损耗(所输送的介质是高温高压介质时更为明显)，同时，球形补偿器的外套管与球体之间密封填料在因为外套管与球体之间的相对运动也会产生损耗(所输送的介质是高温高压介质时更为明显)，这些因素都会导致密封效果下降或失效，从而影响的整个球形补偿器的密封性能。
发明内容
本实用新型要解决的技术问题就是现有的球形补偿器在长期的使用过程中，外套管与球体之间的密封填料在所输送介质的长期冲击下、以及球形补偿器的外套管与球体之间密封填料在因为外套管与球体之间的相对运动，均会使密封填料产生损耗，导致密封效果下降或失效，从而影响的整个球形补偿器的密封性能的问题。
为解决上述技术问题，本实用新型采用如下技术方案：
一种耐磨抗冲击球形补偿器，包括封头、外套管、填料法兰、球体部件，球体部件设置在外套管内，外套管的内壁上设有环形内凸台，填料法兰与外套管通过紧固件连接，填料法兰的内侧设有填料压环，环形内凸台与填料压环之间设有密封填料，其特征在于密封填料与填料压环之间设有抗冲击板，密封填料与球形部件的外表面之间、密封填料与外套管的内表面之间均设有耐磨碳纤维层
为了进一步减少密封填料的磨损，提高密封填料的抗压性能，本实用新型在在环形内凸台与密封填料之间还增加一个抗冲击板。
为了避免密封填料在长期使用中因正常磨损产生空隙，从而影响整个球形补偿器的密封性能，还可在外套管上设置填料加注装置。
本实用新型本实用新型通过抗冲击板的设置，可以有效抗击介质对密封填料的冲击，从而减少密封材料的流失，提高了整个球形补偿器的密封性。通过耐磨碳纤维层的设置，可以有效防止球形补偿器的外套管与球体之间的相对运动使密封填料产生的损耗，从而减少密封材料的流失，以进一步提高了整个球形补偿器的密封性。
