Slot, be also provided on the internal perisporium of the famale connector with two two through-holes being connected of slotting, two through-holes are equal
It is blocked by screw plug, two sliding grooves are respectively the first sliding groove and the second sliding groove, first sliding groove
The left side, which is located on famale connector to be located on male contact with the right of the second sliding groove, is respectively arranged with the first O-ring and the second O-ring,
The periphery wall of the male contact tightens the slip ring for being arranged installation for the first O-ring equipped with one, the famale connector inner wall
On offer the first seal groove placed for the contact of the first O-ring, offer for the second O-ring on the outer wall of the male contact
Contact the second seal groove placed.
In a kind of above-mentioned rotary joint, the both ends of the male contact side are disposed as chamfering.
In a kind of above-mentioned rotary joint, first O-ring and famale connector are slidably matched by slip ring.
In a kind of above-mentioned rotary joint, the through-hole is vertically arranged or is obliquely installed the internal perisporium in famale connector
On.
In a kind of above-mentioned rotary joint, the material of the slip ring is polytetrafluoroethylene (PTFE).
Compared with prior art, this rotary joint has the advantage that
1, this rotary joint is equipped with O-ring seal one and O-ring seal two, strengthens leakproofness；
2, slip ring, steel ball sliding groove and the steel ball in steel ball sliding groove, friction system are provided in this rotary joint
Number reduces, and extends the service life of this rotary joint；
3, steel ball sliding groove top is equipped with nut in this rotary joint, strengthens leakproofness.
4, this rotary joint inner via hole is vertically arranged or is obliquely installed on the internal perisporium of famale connector, prevents rotary joint from falling
When putting, after back-outing screw plug, steel ball is fallen easily.
