产品描述
特点 Features:
该类膨胀节的前部通道端有两个工作波纹管,可以吸收来自弯管段产生的横向位移;后部(平衡端)有一个平衡波纹管,它可以吸收来自直管段轴向位移。当弯管段产生横向位移时,大拉杆上球面螺母绕球面垫圈转动,同时大拉杆承受内压的推力,因此该膨胀节常用于泵、罐、压缩机、汽轮机出口处,以减少对上述设备的作用力。
The front passage end of this type of expansion joints has two working bellows, able to absorb the lateral displacement generated from the curved tube segment; which rear part (balanced end) has a balanced bellow, able to absorb the axial displacement generated from the straight tube segment. When the curved tube segment generates a lateral displacement, the spherical surface nut on the large pull rod rotates around the spherical surface washer, while the large pull rod shall bear the internal pressure pushes, thus this type of expansion joints is generally used at the openings of pumps, cans, compressors and turbines, to reduce the stress laid upon the abovementioned equipment.
