Description

一种新型减震膨胀节
技术领域
本发明涉及机械技术领域，更加具体地说，是涉及一种新型减震膨胀节。
背景技术
减震膨胀节主要用于位移量小，噪音大震动性频繁的泵进出口，主要用于减少管道系统的震动和噪音。目前，传统的泵进出口一般采用橡胶补偿器，而橡胶补偿器存在着不卫生、易老化、脱层撕裂、耐高压性能差，寿命短等致命缺点，特别是用于供热、供暖管道的橡胶补偿器逐渐被新型减震膨胀节所替代。
市场上通用型波纹补偿器由于工艺设备条件限制，所生产的柔性波纹管可吸收管道轴向、横向、角向热变形，吸收震动、降低噪音，耐较高的压力和温度，因柔性波纹管采用的单层不锈钢轴向刚度大，减震降噪效果不如橡胶补器。
发明内容
发明目的：本发明的目的是针对现有技术不足和缺陷，提供了一种新型减震膨胀节，波纹管采用薄壁多层密波结构，柔性好，补偿量大，通过减震杆两端设置的弹簧垫圈、橡胶垫圈的有效配合，利用弹簧及橡胶的柔性吸收系统产生的震动能量。
技术方案：为了实现上述目的，本发明所采用的技术方案为：一种新型减震膨胀节，包括内衬筒、波纹管及两组耳座法兰，所述波纹管设置在内衬筒外侧，所述两组耳座法兰分设在波纹管的两端。所述波纹管的波形呈“Ω”状，所述两组耳座法兰之间设置减震杆，所述减震杆穿过两组耳座法兰的连接孔，并通过紧固连接件进行连接固定，所述紧固连接件包括弹簧垫圈、橡胶垫圈及紧固螺栓，所述弹簧垫圈压在耳座法兰上，橡胶垫圈压在弹簧垫圈上，紧固螺栓压在橡胶垫圈上。
所述减震杆为液压伸缩杆。
所述波纹管为单层不锈钢柔性波纹管。
有益效果：本发明与现有技术相比，其有益效果是：
1、本发明的波纹管采用薄壁多层密波结构，柔性好，补偿量大。
2、本发明的两端连接法兰与耳座为整体结构，耳座与拉杆能承受波纹管变形产生的推力，满足产品的强度要求。
3、本发明通过弹簧垫圈、橡胶垫圈的有效配合，利用弹簧及橡胶的柔性吸收系统产生的振动能量，满足减震要求的同时可防止波纹管因变形太大造成的挤压变形，此设计有效地减少管道系统的震动和噪音，该新型减震膨胀节在通用补偿器上改进了设计方案没有增加过多材料却具备了减震效果好的特点，大大提高产品的竞争力，易被广泛推广使用。
