Abstract
The utility model discloses an L-shaped revolving joint, comprising an L-shaped joint body. The utility model is characterized in that an L-shaped step through hole is arranged in the L-shaped joint body; one end of the L-shaped joint body is connected to a swivel nut which is capable of mutually rotating with the L-shaped joint body; the other end of the L-shaped joint body is a cone-shaped end; a ring-shaped groove is arranged at a place adjacent to the cone-shaped end; an external thread is arranged at a place adjacent to the ring-shaped groove; the external thread is connected to a nut. The utility model is advantageous in that the structure is simple; the connection is reliable; the air-tightness is stable; one end of the revolving joint has the function of rotating.
Description
Technical field
The utility model discloses a kind of L type swivel joint, be mainly used in the pipe connection systems such as Oil, Water, Gas in the various machinery, belong to the pipeline connecting parts technical field.
Background technique
Pipe joint is widely used in oil, water, connection between delivery lines such as gas, generally can be divided into straight coupling, L type joint, T connector, wherein L type joint comprises L type joint body, and respectively be provided with screw thread at the two end part of L type joint body, during butt joint, as long as the nut driving that will be arranged on the flexible pipe can be realized the pipeline purpose of connecting at the screw thread place of L type joint body, but L type joint exists such problem: after an end of L type joint is connected with flexible pipe and tightens, the other end must be fixed on one towards last, and this can not guarantee and can just be connected with another pipeline towards last tip side, one end that may need the to tighten angle of circling round will reduce the sealability of its connection like this.Simultaneously, some flexible pipe is not threaded with L type joint body, and just flexible pipe inserts in the port of L type joint body, and it is not firm to exist connection, the problem that comes off easily.
The model utility content
For addressing the above problem, it is a kind of simple in structure that the utility model purpose is to provide, and it is firm to connect, and have stable tightness and the L type swivel joint of an end with spinfunction wherein.
The technological scheme that its technical problem that will solve the utility model adopts is: a kind of L type swivel joint, comprise L type joint body, in L type joint body, has L type ladder hole, end at L type joint body is connected with a swivel nut, this swivel nut can rotate mutually with L type joint body, is cone-shaped end at the other end of L type joint body, is provided with annular groove at the adjacent of cone-shaped end, the adjacent of annular groove has outside thread, is connected with nut on this outside thread.
Of the present utility modelly further be set to: described swivel nut is made of a convex shoulder, each axle journal of convex shoulder both sides, be provided with a circle curve bath at described convex shoulder place, and the end of the L type joint body that is connected with nut is provided with an annular flange flange, and this annular flange flange and curve bath are combined together.Setting can be with swivel nut and L type joint body close-fitting together like this, and can rotate mutually.
One axle journal of described swivel nut puts in the L type ladder hole, and is provided with a seal ring I on axle journal, and setting can improve the sealing between swivel nut and the L type joint body like this, prevents that leakage situation from appearring in fluid.Outer surface on another axle journal of swivel nut has screw thread, and this screw thread can be connected with pipe fitting.
Described nut is provided with center hole vertically, this center hole bottom is a tapped hole, top is step hole, described tapped hole can be connected with above-mentioned outside thread, the design of step hole is up-small and down-big because of its internal diameter, and the internal diameter smaller portions can be oppressed flexible pipe makes flexible pipe be connected more firm with the termination portion of L type joint body.
After the utility model adopts said structure, after swivel nut is connected with pipe fitting and tightens, L type joint body can rotate on swivel nut, by rotate determine L type joint body towards, at this moment, cone-shaped end place at the other end of L type joint body can be connected with flexible pipe, so just need not reduce the connection that sealing just can be finished pipeline.When above-mentioned cone-shaped end place is connected with flexible pipe, shifts flexible pipe onto the annular groove place, and screw nut, make this nut oppress flexible pipe, make its connection more firm than small end.Above-mentioned cone-shaped end is that conical design can be more smooth and easy when promoting flexible pipe.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model L type joint body structural representation;
Fig. 3 is the utility model swivel nut structural representation;
Fig. 4 is the utility model nut structure schematic representation.
Embodiment
With reference to Fig. 1, Fig. 2, shown in Figure 3, a kind of L type swivel joint, comprise L type joint body 1, swivel nut 3, in L type joint body 1, has L type ladder hole 2, and be provided with an annular flange flange 9 in an end of L type joint body 1, described swivel nut 3 is made of a convex shoulder 31, each axle journal 32,33 of convex shoulder 31 both sides, be provided with a circle curve bath 8 at described convex shoulder 31 places, this curve bath 8 is combined together with described annular flange flange 9, after cooperating, swivel nut 3 and L type joint body 1 close-fitting and can rotate together mutually.The other end at L type joint body 1 is a cone-shaped end 4, is provided with annular groove 5 at the adjacent of cone-shaped end 4, and the adjacent of annular groove 5 has outside thread 6, is connected with nut 7 on this outside thread 6.
See Fig. 1 again, in order to improve the connection sealing, an axle journal 32 of described swivel nut 3 puts in the L type ladder hole 2, and is provided with a seal ring I 11 on axle journal 32.Outer surface on another axle journal 33 of swivel nut 3 has screw thread 34, can be connected with pipe fitting by screw thread 34.
See Fig. 4, described nut 7 is provided with center hole 71 vertically, and these center hole 71 bottoms are tapped hole, and top is step hole.
When the utility model uses, after swivel nut 3 is connected with pipe fitting and tightens, L type joint body 1 rotates on swivel nut 3, by rotate determine L type joint body 1 towards, at this moment, just can be connected with flexible pipe, so just need not reduce the connection that sealing just can be finished pipeline at cone-shaped end 4 places of the other end of L type joint body 1.When above-mentioned cone-shaped end 4 places are connected with flexible pipe, shift flexible pipe onto annular groove 5 places, prevent that it from coming off, and screw nut 7, make this nut 7, make its connection more firm than small end compressing flexible pipe.
