Description
Technical field
The utility model relates to a kind of joint of mechanical field, relates in particular to a kind of rotating joint of steel ball that has.
Background technique
Usually there is swivel to be connected between flowing medium fixing tube and rotation or reciprocating equipment or the pipeline, Chang Yong joint comprises blind flange, inner sleeve, outer sleeve in the market, blind flange is by the end of screw at inside and outside sleeve, and be provided with packing ring between blind flange and the screw, the primary seal circle is installed on the inwall of blind flange, the outside of this primary seal circle is near the end face of inside and outside sleeve contacting point, inner sleeve is provided with annular groove, be placed with steel ball in this annular groove, and the through hole of stuffing box gland hermetically sealed case tube is arranged.Because blind flange, the inside and outside sleeve of this swivel all are to have carbon steel material to process, weight is heavier, uses inconvenient; And inside and outside sleeve directly contacts, and damages because of friction easily, thereby has reduced swivel working life, causes often changing the trouble of swivel.
The model utility content
The utility model provides a kind of lighter, anti abrasive swivel free to rotate.
In order to solve the problems of the technologies described above, swivel of the present utility model comprises blind flange, inner sleeve, outer sleeve, described blind flange is by the end of screw at inner sleeve and outer sleeve, and also be lined with packing ring between blind flange and the screw, inner chamber at blind flange is equipped with the primary seal circle, better seal action is played near the end face of inner and outer sleeves contacting point in the outside of this primary seal circle.Lubricating cup is installed on the outer sleeve.Described blind flange and inside and outside sleeve all are to have aluminum alloy material to process, and be in light weight.And also be with stainless steel sleeve between inside and outside sleeve, this stainless steel sleeve is made up of interior steel bushing and outer steel sleeve, and wherein interior steel bushing is enclosed within on the described inner sleeve and by pin to be fixed, and has annular groove in described on the steel bushing, and the cross section of this annular groove is semicircle; Described outer steel sleeve is nestable outside interior steel bushing, is drilled with the tapped through hole of mutual perforation and concentric on this outer steel sleeve and outer sleeve, this tapped through hole with described in annular groove on the steel bushing corresponding; Described outer steel sleeve is by inserting the interior screw of this tapped through hole on described outer sleeve, and the steel ball that is contained in this screw below falls in the described annular groove.The tapped through hole outside at described outer steel sleeve has annular seal groove, in the sealing groove seal ring is housed, and the sealing circle is close to the outer surface of described interior steel bushing.
Because the blind flange of swivel of the present utility model, inside and outside sleeve have alleviated the weight of swivel greatly all with aluminum alloy material processing, use convenient; Anti abrasive stainless steel sleeve is installed between inner sleeve and the outer sleeve, has reduced wearing and tearing, increased the working life of swivel.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
