什么是橡膠軟接頭位移超限？

   What is the rubber soft joint displacement overrun?

橡膠軟接頭在外觀上實際上有別于單球橡膠軟接頭。其安裝長度大于單球橡膠軟接頭，解決了橡膠軟接頭安裝長度短的問題。安裝較長的橡膠接頭時可使用雙球橡膠軟接頭，但在安裝過程中嚴禁安裝雙球橡膠接頭。雙球橡膠軟接頭在平地、懸掛和垂直安裝時，其實際軸向位移壓力小于管道的支撐力，否則應(yīng)安裝防拔裝置，防止工作時的壓力脫落。

   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.

在管道施工過程中，必須有固定支座或支架，固定支架的受力必須大于軸向力。產(chǎn)品的垂直安裝和頂部安裝應(yīng)安裝在固定支架和力托架的兩端，以防止張力后的工作。雙球橡膠軟接頭安裝螺栓應(yīng)逐步對稱擰緊，防止局部泄漏，安裝時應(yīng)遠離熱源，嚴禁使用不符合本產(chǎn)品要求的介質(zhì)。

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.
