Embodiment
The utility model comprises as shown in Figure 1 and Figure 2: housing 8 has spline nose 5 on the housing 8.The left side of housing 8 is fixedly connected with threeway or two and leads to 1, and design has an annular seating 7 in the housing 8, and annular seating 7 is divided into left and right sides two-part with housing 8, and design has stress breathing hole 6 on the annular seating 7.Hollow shaft 14 is installed in the housing 8, and the left end of hollow shaft 14 is fixedly connected with hemisphere ring 3, and hemisphere ring 3 is fixed on the hollow shaft 14 by screw thread, and the left side of hemisphere ring 3 is fixed with locking nut 2.On hollow shaft 14, the right side of hemisphere ring 3 is with seal ring 4, seal ring 4 is a graphite-seal ring, the left end of seal ring 4 has the rounded channels with hemisphere ring 3 end surface shape coupling, the outer ring surface of seal ring 4 has tapering.Be with sliding bearing 9 on the right side hollow shaft 14 of the annular seating 7 in housing 8, sliding bearing 9 is a graphite sliding bearing.Have circular groove on the sliding bearing 9, spring seat cushion 10 is installed in the circular groove.The right side of sliding bearing 9 is equipped with spring 11, and the right side of spring 11 is fixedly mounted on the hollow shaft 14 for location locknut 12, location locknut 12.Symmetry has heat radiation observation panel 16 (in addition referring to Fig. 2) on the housing 8.
The utility model swivel joint, rational in infrastructure, component is few, is easy to assembling, can satisfy superhigh temperature, the demand of extra-high-speed temperature.It mainly is threeway (two-way circulating) or two logical (one-way flows), formations such as inserted graphite-seal ring, hemisphere hollow shaft, sliding bearing (graphite, other materials also can), spring and location locknut.In case of necessity, also can between spring and location locknut, install plane bearing additional, to improve rotating speed.In the installation process of integral body, at first ready-made inserted graphite-seal ring in advance is embedded in the annular seating of housing, make it smooth and again sliding bearing and spring seat cushion are placed in the lump the other end of housing with one heart, and then spring is placed on the spring seat cushion.At the end that threeway combines with housing the hemisphere hollow shaft is passed in the middle of inserted seal ring, when passing the housing the other end, the screw thread of hollow shaft exposes again.At this moment again the location locknut is tightened on the hollow shaft.At this moment spring force is converted into pulling force, and spring is tightly held hemisphere ring on the hollow shaft under the stopping of location locknut, make it closely card be combined on the graphite-seal ring, to reach the purpose of sealing.Otherwise: at swivel joint with after running device is connected, after medium flows into, certain pressure is arranged in the cavity, if pressure is that spring is promptly ineffective greater than pressure (the being pulling force) working state at this moment of spring so, under such operating conditions, the working life of spring can be longer so.Design has the eave tile driving hole on the end face of positioning and locking nut, so that loading and unloading, design has location jackscrew screw on cylindrical again, in case move back certainly.Then threeway or two logical is coupled together with bolt with housing, the centre adds sealing gasket, screws bolt, with anti-leak.So far, Zheng Ti assembling work is finished.Equipment connection port 15 can be screw connection structure, also can make the fast-assembling flanged connecting structure.
