什么是橡胶软接头位移超限？

   What is the rubber soft joint displacement overrun?

橡胶软接头在外观上实际上有别于单球橡胶软接头。其安装长度大于单球橡胶软接头，解决了橡胶软接头安装长度短的问题。安装较长的橡胶接头时可使用双球橡胶软接头，但在安装过程中严禁安装双球橡胶接头。双球橡胶软接头在平地、悬挂和垂直安装时，其实际轴向位移压力小于管道的支撑力，否则应安装防拔装置，防止工作时的压力脱落。

   Rubber soft joint is actually different from single ball rubber soft joint in appearance.The installation length is longer than that of single ball soft rubber joint, which solves the problem of short installation length of soft rubber joint.Double ball rubber soft joint can be used when installing long rubber joint, but it is forbidden to install double ball rubber joint during the installation process.When the double ball rubber soft joint is installed in flat, suspended and vertical, its actual axial displacement pressure is less than the supporting force of the pipe, otherwise the anti-pulling device should be installed to prevent the pressure falling off during work.

在管道施工过程中，必须有固定支座或支架，固定支架的受力必须大于轴向力。产品的垂直安装和顶部安装应安装在固定支架和力托架的两端，以防止张力后的工作。双球橡胶软接头安装螺栓应逐步对称拧紧，防止局部泄漏，安装时应远离热源，严禁使用不符合本产品要求的介质。

In the process of pipeline construction, there must be fixed support or support, the force of the fixed support must be greater than the axial force.The vertical and top installation of the product shall be installed at both ends of the fixing bracket and the force bracket to prevent post-tension work.Installation bolts of double ball rubber soft joint should be tightened symmetrically step by step to prevent local leakage. During installation, keep away from heat source and do not use media that does not meet the requirements of the product.
