Abstract
The utility model discloses a quick connector, which comprises a female connector (1), a sealing ring (2) located in the female connector (1), and a male connector (6). An insertion end of the male connector (6) is inserted with the female connector (1). The quick connector further comprises a retaining ring (3) located in a groove of the female connector (1), and the sealing ring (2) is mounted in the groove. By utilizing the structure, safety coefficient of use can be guaranteed, and thereby the utility model is adaptable to non-leakage connection of middle-high pressure fluid piping systems with pressure above 3.5MPa.
Description
Technical field
The utility model relates to a kind of pipe joint, specifically is a kind of rapid pipe joint that is used for the mesohigh fluid piping system.
Background technique
In hydraulic plumbing system, the joint that traditional connection pipe fitting is used couples together two pipe fittings by thread connecting mode, adopt this thread connecting mode to distinguish mantle fiber at two of two pipe fittings, working efficiency is low when not only connecting, and leakage is caused because of poorly sealed easily in the joint.In order to address this problem, people have developed rapid pipe joint, it comprises negative joint and male connector, negative joint is the cylindrical body of hollow, be formed with opposing L shape hole on the cylindrical body, an end of male connector forms bayonet end, forms relative projection on bayonet end, each projection is positioned respectively promptly to reach the purpose of quick assembling in each opposing L shape hole.But this rapid pipe joint only is applicable to loose low pressure connections such as gas piping, can not be used to have big pressure (promptly greater than 3.5MPa) and the pressure piping connection higher to the connection requirements of tightness.
The model utility content
Technical problem to be solved in the utility model is that a kind of rapid pipe joint that can be applicable to that mesohigh (promptly greater than 3.5MPa) fluid piping system connects is provided.
For solving the problems of the technologies described above, a kind of rapid pipe joint that the utility model provides, comprise negative joint, be positioned at seal ring, the male connector of negative joint, the bayonet end of described male connector is pegged graft with negative joint and is cooperated, this rapid pipe joint also comprises back-up ring, and described back-up ring is positioned at the groove that seal ring is housed on the negative joint.
After adopting above structure, owing to increased back-up ring at the seal ring place, limited the distortion of seal ring in use, thereby guaranteed the safety coefficient of using, be applicable to that therefore pressure is greater than there not being leakage phenomenon in the mesohigh fluid piping system connection of 3.5MPa.
As improvement, described back-up ring is meant to be positioned at the one side of inserting mouth near negative joint in groove.So just can when male connector inserts negative joint, prevent the seal ring extrusion, thereby more can improve the safety coefficient of use.
As further improvement, described rapid pipe joint also comprises opens ring, and described negative joint is shaped on internal channel, and along the circumferential direction has one section opening at the internal channel place, described unlatching ring is positioned at the internal channel of negative joint, and two end was worn opening and stretched out outside the negative joint.After adopting this structure, make the grafting of rapid pipe joint more convenient flexibly.
As further improving, the bayonet end of described male connector is provided with annular shoulder block, and the conical surface in conical surface on the described annular shoulder block and the negative joint matches.After adopting this structure, male and female connector grafting back is cooperated more fit, more guarantee the safety coefficient of mesohigh fluid piping system.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of Fig. 1, Fig. 2, the utility model rapid pipe joint shown in Figure 3 as can be known, the utility model rapid pipe joint, comprise negative joint 1, be positioned at seal ring 2, the male connector 6 of negative joint 1, the bayonet end of described male connector 6 is pegged graft with negative joint 1 and is cooperated, this rapid pipe joint also comprises back-up ring 3, and described back-up ring 3 is positioned at the groove that seal ring 2 is housed on the negative joint 1.Described back-up ring 3 is meant to be positioned at the one side of inserting mouth near negative joint 1 in groove.Described rapid pipe joint also comprises opens ring 5, described negative joint 1 is shaped on internal channel 4, and along the circumferential direction have one section opening 7 at internal channel 4 places, and described unlatching ring 5 is positioned at the internal channel 4 of negative joint 1, and two end pin 8 passes opening 7 and stretches out outside the negative joint 1.The bayonet end of described male connector 6 is provided with annular shoulder block 11, and conical surface 10 on the described annular shoulder block 11 and the conical surface 9 in the negative joint 1 match.
During installation, earlier seal ring 2, back-up ring 3 are pressed in the groove of negative joint 1, two end pin 8 opening ring 5 are compressed again, in the internal channel 4 of the negative joint 1 of packing into, two end pin 8 passes the opening of negative joint 1, decontrols end pin 8 then.
During use, male connector 6 is inserted in the negative joint 1, utilize the end face of male connector 6 to prevent dust, and guarantee that by back-up ring 3 and seal ring 2 joint does not have leakage.When opening, strut two end pin 8 opening ring 5, male connector 6 just can be thrown off smoothly with negative joint 1 like this.Realize the connection of rapid pipe joint and the action of unloading like this.
Claims (4)
