Embodiment
With reference to Fig. 1-Fig. 3, the utility model is described further.
A kind of joint, comprise joint body 1, the first flow 11, arced flow path 12 and the second runner 13 that are communicated with successively is provided with in described joint body 1, the center line of first flow 11 and the central axis of the second runner 13, the direction that fluid is come in is vertical with direction out, changes circulating direction.One end of joint body 1 is connected with flange seal end face 2, flange seal end face 2 is provided with closure gasket groove 21, the outer wall of the other end is provided with the first annular groove 101, second annular groove 102, the 3rd annular groove 103, the 4th annular groove 104, first back-up ring 3 and the second back-up ring 4 successively, draw-in groove 5 is formed between first back-up ring 3 and the second back-up ring 4, first back-up ring 3 is provided with First Transition cambered surface 31 with the joint of joint body 1, second back-up ring 4 comprises oblique anchor ring 41, and described oblique anchor ring 41 is provided with the second transition cambered surface 42 with the joint of joint body 1.
First Transition cambered surface 31 is provided with the joint of joint body 1 by the first back-up ring 3, add the surface stress of the first back-up ring 3 and joint body 1, make the first back-up ring 3 more firm with the connection of joint body 1, second back-up ring 4 comprises oblique anchor ring 41, be designed to oblique anchor ring 41, strengthen the structural strength of joint body 1, oblique anchor ring 41 is provided with the second transition cambered surface 42 with the joint of joint body 1, add the surface stress of the second back-up ring 4 and joint body 1 joint, make the second back-up ring 4 more firm with the connection of joint body 1, and then it is more stable when locating to make to form draw-in groove 5 between the first back-up ring 3 and the second back-up ring 4, locating effect is better.
One end of joint body 1 is connected with flange seal end face 2, the external diameter of flange seal end face 2 is established larger than the external diameter of joint body 1, flange seal end face 2 plays the effect of sealing, meanwhile, is provided with closure gasket groove 21 at flange seal end face 2, fitted seal packing ring, make sealing effect better, meanwhile, the external diameter of flange seal end face 2 is larger than the external diameter of joint body 1, utilize positioning device to be stuck in flange seal end face 2 and the joint of joint body 1, effectively play the effect of sealing.
Further, described 4th annular groove 104 is provided with transition collar 105, and the exterior contour of transition collar 105 is round table-like, and the minimum outer diameter of transition collar 105 is identical with the external diameter of joint body 1.
Further, the distance between described second annular groove 102 and the 3rd annular groove 103 and the distance ratio between the 3rd annular groove 103 and the 4th annular groove 104 are 1:1.
Under the mated condition of restraint zone, more firm when joint body 1 being connected by several annular grooves that interval is identical with sebific duct.
Further, the distance between described first annular groove 101 and the second annular groove 102 and the distance ratio between the second annular groove 102 and the 3rd annular groove 103 are 1:2.
Because the first annular groove 101 and the second annular groove 102 are relatively near the port of joint body 1, therefore, port needs larger fixing external force, just can make sebific duct and joint body 1 effectively fixing, so the distance between the first annular groove 101 and the second annular groove 102 is established closer.
The minimum outer diameter of transition collar 105 is established identical with the external diameter of joint body 1, sebific duct is made easily to be enclosed within joint body 1, and sleeve pipe is when packing into transition collar 105, sebific duct can prop up in the maximum outside diameter place of transition collar 105, increase frictional force, until sebific duct touches the first back-up ring 3 position, at cooperation restraint zone, be provided with the first annular groove 101 respectively, second annular groove 102, the position of the 3rd annular groove 103 and the 4th annular groove 104 puts restraint zone, make restraint zone spacing, increase frictional force, and then make sebific duct and joint body 1 difficult drop-off when being connected with hydraulic pressure, the phenomenon of water resources of effectively avoiding waste occurs.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
