膨脹節(jie)習(xi)慣上也(ye)叫補(bu)償(chang)(chang)器(qi),或(huo)伸(shen)縮(suo)節(jie)。由構(gou)成其工(gong)作主體(ti)的(de)波紋管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(一(yi)種彈(dan)性元件)和(he)端(duan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、支架、法蘭、導管(guan)(guan)(guan)(guan)(guan)(guan)(guan)等(deng)(deng)附件組成。 膨脹節(jie)是(shi)為了補(bu)償(chang)(chang)因溫度差與機(ji)械振(zhen)動引起的(de)附加應力,而設置在(zai)(zai)容器(qi)殼體(ti)或(huo)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)上的(de)一(yi)種撓性結構(gou)。利用其工(gong)作主體(ti)波紋管(guan)(guan)(guan)(guan)(guan)(guan)(guan)的(de)有效(xiao)伸(shen)縮(suo)變形(xing)(xing),以吸收管(guan)(guan)(guan)(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、容器(qi)等(deng)(deng)由熱(re)脹冷縮(suo)等(deng)(deng)原(yuan)因而產生(sheng)的(de)尺寸變化,或(huo)補(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、容器(qi)等(deng)(deng)的(de)軸向(xiang)、橫向(xiang)和(he)角向(xiang)位(wei)移。也(ye)可(ke)用于降噪減(jian)振(zhen)。供(gong)熱(re)上,為了防止供(gong)熱(re)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)升溫時,由于熱(re)伸(shen)長或(huo)溫度應力而引起管(guan)(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)變形(xing)(xing)或(huo)破壞,需要(yao)在(zai)(zai)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)上設置補(bu)償(chang)(chang)器(qi),以補(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)的(de)熱(re)伸(shen)長,從而減(jian)小管(guan)(guan)(guan)(guan)(guan)(guan)(guan)壁的(de)應力和(he)作用在(zai)(zai)閥件或(huo)支架結構(gou)上的(de)作用力。
