Back of the body cap profile is a cylinder, and cylinder comprises cylinder, hexagonal prism body or cubic cylinder.Inside one end of back of the body cap is an internal thread, and the back of the body cap other end has centre bore.Annular boss on the male joint outer wall can be by the centre bore of back of the body cap.
Between male joint and back of the body cap, be with retaining ring.Retaining ring is split type.The endoporus of retaining ring cooperates with the outer wall of male joint, and the retaining ring outer wall cooperates with back of the body cap centre bore.The outer wall of retaining ring has step, and the stepped diameters of retaining ring outer wall is greater than the center-hole diameter of back of the body cap.
There is endoporus the end of female joint, and the inner hole sleeve of female joint end is in the male joint end.
In order to make split type retaining ring become as a whole and to be connected with back of the body cap, the jump ring groove is arranged on the outer wall of retaining ring, an axle check ring is arranged in the jump ring groove.
Described retaining ring is formed an annular by 2~4 secter pats.
Easy accessibility has symmetrical installing hole on the outer wall of back of the body cap for convenience.Can insert iron staff in the installing hole, rotation back of the body cap.
Installation process of the present utility model: consult Fig. 5.In the seal groove of male joint 1, install sealing ring; To carry on the back cap 5 and be enclosed within the male joint 1, and on push away the back of the body cap 5; Split type retaining ring 2 is enclosed within on the outer wall of male joint 1 becoming an annular; Drop-down back of the body cap 5 and retaining ring 2 are passed the centre bore 10 of back of the body cap 5; Snap in axle in the jump ring groove of retaining ring 2 with check ring 3; The end of female joint 7 is enclosed within the end of male joint 1; Screw back of the body cap 5 and make the top of female joint 7 compress the boss 9 of male joint 1, finish the installation of high-voltage quick joint.The process of dismounting, replacing back of the body cap 5 is operated in reverse order and is got final product.
The beneficial effects of the utility model: high-voltage quick joint adopts split type retaining ring structure, can change the back of the body cap after the damage easily; Between male joint and female joint, sealing ring is arranged in addition, improved the sealing of snap joint.High pressure line snap joint also has connection fast, safe and reliable characteristics.
