用于估算波纹管伸缩节变形量的装置
摘要：
本发明属于电厂锅炉技术领域，具体涉及一种用于估算波纹管伸缩节变形量的装置，包括基座以及设置于基座两侧的定位滑竿以及定位支架，定位滑竿与基座之间设置有滑移组件，定位滑竿与定位支架上套接有三通套筒以及定位组件，两个三通套筒之间的自由端相对应且两个三通套筒的自由端之间固接有弹簧，弹簧中部固定套接有直套筒，直套筒的长度小于弹簧处于两个所述三通套筒之间的长度。该用于估算波纹管伸缩节变形量的装置能够模拟估算出锅炉在受热膨胀以后波纹管伸缩节所产生的变形量，从而利用反向预留变形量来抵消锅炉在工作受热后所产生的膨胀量，防止波纹管伸缩节或管道会与钢梁发生接触造成膨胀受阻。
摘要（英）：

The invention belongs to the technical field of power plant boilers, and in particular relates to a device used for estimating deformation of a bellow expansion joint, the device comprises a base, a positioning slider rod and a positioning bracket, the positioning slider rod and the positioning bracket are arranged on both sides of the base, a sliding component is arranged between the positioningslider rod and the base, the positioning slider rod and the positioning bracket are sleeved with tee-joint sleeves and positioning components, the free ends of the two tee-joint sleeves are corresponding to each other, a spring is fixedly connected between the free ends of the two tee-joint sleeves, the middle part of the spring is fixedly sheathed with a straight sleeve, and the length of the straight sleeve is less than the length of the spring between the two tee-joint sleeves. The deformation of the bellow expansion joint after thermal expansion of a boiler can be simulated and estimated by the device used for estimating the deformation of the bellow expansion joint, the amount of expansion generated after heating of the boiler in working can be offset by reverse reserved deformation,and expansion resistance caused by contact of the bellow expansion joint or a pipe with a steel beam can be prevented.
