Technical Field
[0001] The utility model relates to the technical field of hydraulic joints, in particular to an anti-separation threaded hydraulic joint. Background Art
[0002] Threaded hydraulic joints are a type of connection element, mainly used for connecting pipes in hydraulic systems. While connecting the pipes, they can seal the connecting pipes through internal gaskets and sealing rings. They are mainly used in industries such as electricity and petroleum, and can ensure the stable operation and safety of the hydraulic system.
[0003] During installation, two sets of connecting pipes are placed inside the joint, and one end of the connecting pipe is compressed by two sets of bolts. The connecting pipe can be fixed and sealed by the pressure of the bolts. The connecting pipe will be subjected to vibrations in multiple directions during use. When the vibration is transmitted to the bolts, the bolts will become loose. At this time, one end of the connecting pipe fixed by the bolts will have a poor sealing problem, which will cause leakage at the connection and affect the normal operation. For this reason, we propose an anti-detachment threaded hydraulic joint. Utility Model Content
