Introduction to anti slip sleeve:
Anti slip ferrule is also called anti slip device, anti slip clamp of quick coupler, anti slip clamp of quick coupler, anti slip clamp of crane tube, anti slip clamp of quick coupler of loading and unloading truck, and safety anti slip fastener. It is a protective device for quick connector, loading arm and loading arm connecting port reinforcement to prevent the thread from cracking and falling off.
Screw valves and quick fitting connectors are used in the loading arm or filling hose, and the part connected to the tanker. During the filling operation, there are two potential safety hazards. One is that after long-term use of the quick fitting connector, a certain amount of wear will occur in the steel ball, the steel ball holder and the groove of the quick fitting connector in the lock sleeve, while there are no clear requirements for the detection of wear degree and the replacement time of the quick fitting connector, If the inspection is not in place before the filling operation, the pressure fluctuation is frequent, the fluctuation amplitude is large, and the stress distribution is uneven during the filling. When filling to the medium and high pressure, it is easy to be washed off, and the washed out loading arm or filling hose may cause equipment damage or personal injury. The second is that the operator did not install the movable lock package in place, and when opening the gas valve to fill to medium and high pressure, he flushed the loading arm or filling hose away, which may cause equipment damage or gas/liquid leakage accidents.
The quick connector anti slip sleeve eliminates the potential safety hazard of loose and falling off quick connector and valve interface, and plays an important role in the safety of flammable gas/liquid medium filling operation. At the same time, it can also avoid the loosening caused by the operator's failure to install the movable lock sleeve of the quick fitting connector in place, and completely eliminate the potential safety hazard.
