             详细介绍

             金属膨胀节

                    金属膨胀节 主要用于补偿管路或设备因温差或温度波动造成的轴向、损向和角向位移,同时也可以吸收高频机器进出口管道的震动。
                    按ISO15348标准规定,根据金属膨胀节吸收位移的特点将膨胀节分为四大类型:轴向型膨胀节、角向型膨胀节、横向型膨胀节、万能型膨胀节四大类型,同时将万能型膨胀节又细分为非压力平衡万能型和压力平衡万能型两类。
            1、单式轴向型:单式轴向型波纹膨胀节由一个波纹管及结构件组成,主要用于吸收轴向位移而不能承受波纹管压力推力的膨胀节.连接形式有两种:焊接连接、法兰连接
            2、单式铰链型:单式铰链型膨胀节由一个波纹管及销轴、铰链板和壁板等结构件组成,只能吸收一个平面内的角位移并能承受波纹管压力推力的膨胀节。连接形式:焊接连接、法兰连接
            3、单式万向铰链型:单式万向铰链型膨胀节由一个波纹管及销轴、铰链板、万向环和立板等结构件组成,能吸收?#25105;?#24179;面内的角位移并能承受波纹管压力推力的膨胀节.连接形式有两种:焊接连接、法兰连接
            4、复式自由型:复式自由型膨胀节由中间管所连接的两个波纹管及结构件组成,主要用于吸收轴向与横向组合位移而不能承受波纹管压力推力的膨胀节。连接形式有两种:焊接连接、法兰连接
            5、复式拉杆型:复式拉杆型膨胀节由中间管所连接的两个波纹管及拉杆、端板和球面与锥面垫圈等结构件组成,能吸收?#25105;?#24179;面内的横向位移并能承受波纹管压力推力的膨胀节。
            6、复式铰链型:复式铰链型膨胀节是由中间管所连接的两个波纹管及销轴、铰链板、和立板等结构件组成,只能吸收一个平面内的横向位移并能承受波纹管压力推力的膨胀节。
            7、复式万向铰链型:复式万向铰链型膨胀节是由中间管所连接的两个波纹管及十字销轴、铰链板和立板等结构件组成,能吸收?#25105;?#24179;面内的横向位移并能承受波纹管压力推力的膨胀节.
            8、弯管压力平衡型:弯管压力平衡型膨胀节由一个工作波纹管或中间管所连接的两个工作波纹管和一个平衡波纹管及弯头或三通、封头、拉杆、端板和球面与锥面垫圈等结构件组成,主要用于吸收轴向与横向组合位移并能平衡波纹管压力推力的膨胀节。
            9、直管压力平衡型:直管压力平衡型膨胀节由位于两端的两个工作波纹管和位于中间的一个平衡波纹管及拉杆和端板等结构件组成,主要用于吸收轴向位移并能平衡波纹管压力推力的膨胀节。
            10、外压单式轴向型:外压单式轴向型膨胀节由承受外压的波纹管及外管和端管等结构组成,只用于吸收轴向位移而不能承受波纹管压力推力的膨胀节
