During the use of the sleeve joint, there may be leakage, so we can take relevant measures to prevent such phenomena from occurring. The leakage prevention measures are as follows:
For sleeve joints, leakage is mostly caused by the loosening of the pneumatic ball valve sleeve or deformation of the pipe end face due to significant external or impact forces on the pipeline. At this time, it is necessary to check whether the sleeve is out of round, whether the blade is damaged, whether the pipe end is intact, and the degree of compression of the sleeve nut. At the same time, the external force on the pipeline should also be removed. For flared pipe joints, leakage is often caused by excessive expansion, unsatisfactory quality, or multiple disassembly, resulting in deformation or cracks in the expansion. In this case, the front end can be cut off and re expanded.
Choose a new one with the same outer diameter and a thicker cross-section“ о” The sealing surface with a stop groove can also be cut or ground to reduce the depth of the stop groove, so as to“ о” The ring has sufficient elastic deformation. If there is a leak at the pipe joint using oil resistant rubber sheet, wool felt, soft steel cardboard, combined sealing gasket or sealant, regardless of the material, the sealing part of the sleeve joint should be checked for damage, deformation, aging, and excessive roughness, and then corresponding measures should be taken.
