单式铰链波纹膨胀节主要由接管，立板，铰链板，销轴，波纹管组成。产品型号：WXJB
口径：DN100-DN3500
工作压力：0.25-2.5Mpa
性能特点：此类膨胀节由接管，波纹管及接管相连的一对铰链构成。它只能吸收单平面的角向位移。吸收位移时应有两个或三个角向型膨胀节组合使用。膨胀节的铰链具有承受内压推力的能力。
product type：WXJB caliber：DN100-DN3500
working pressure ：0.25-2.5Mpa
Features:Such expansion joint consists of the takeover , a large tie and other parts . lt can absorb the lateral displacement of any plane . When the displacement happens, the spherical nut on the large tie rotates around the sphericalwasher, meanwhile the large tie also has the ability to withstand the internal thrust force.
