Preferably, the inner wall of the pipe fitting body back segment is equipped with the first seal groove, it is equipped with first seal groove First sealing ring.
Preferably, the connecting sleeve is equipped with the second taper surface, the taper and the first taper surface of second taper surface Identical, second taper surface is engaged with the first taper surface.
Preferably, the quantity of the steel ball is several.
Preferably, the outer wall of the pipe fitting body leading portion is equipped with external screw thread, the external screw thread and loose joint nut phase Coordinate.
The beneficial effects of the utility model:The utility model by connecting sleeve and the 3rd sealing ring, elastic sealed body and The tight fit of steel ball, has reached good sealing effect;Pipe fitting body and connecting sleeve is set more to step up by loose joint nut Closely connected merging clamping tube body, ensure that the fixing of pipe fitting, is easy for installation and removal, improve work efficiency;It is close by first The cooperation of sealing groove, the first sealing ring, the second seal groove and the second sealing ring, further strengthens leakproofness.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
