Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing 1~4, a kind of hydraulic system loose flange, including pipeline coupling flange 1, it further include connecting with pipeline
The loose flange 2 that acting flange 1 is connected, loose flange 2 include hollow stationary housing 201, piston like motion body 202 and limit
Position nut 203, axial seal 204, piston like motion body 202 is axial to be set to inside stationary housing 201, and 203 sets of stop nut
It connects on piston like motion body 202 and close to pipeline coupling flange 1, axial seal 204 is socketed on piston like motion body 202
And far from pipeline coupling flange 1；Piston like motion body 202 is equipped with the lug boss 202a for resisting 203 end of stop nut.
During specific implementation, the utility model is connected to the pipeline of hydraulic system by pipeline coupling flange 1
On, when having pressure oil to pass through in hydraulic system, pipeline coupling flange 1 and piston like motion body 202 are passed sequentially through, when flowing through work
When the inside of plug movable body 202, due to there is the impact vibration of pressure oil, certain damage can be brought to link position, works as utilization
The utility model is arranged in link position, when encountering the impact for having pressure oil, under force, piston like motion body 202
A degree of movement is had, weakens the percussion of pressure oil in the process of movement, reduces the damage to system；When
When a degree of loosening occurs in piston like motion body 202, due to being socketed with stop nut 203 outside it, when stop nut 203
When being moved with piston like motion body 202, it will receive the conflict of the lug boss 202a on piston like motion body 202, limit its fortune
