Abstract
The utility model discloses a connecting device for a high-temperature gas connecting pipeline. The connecting device comprises two connecting pipes in butt joint, annular convex ridges are arranged on the outer circumferential surfaces of the adjacent end portions of the two connecting pipes respectively, annular grooves are formed in the inner circumferential surfaces of the adjacent end portions of the two connecting pipes, elastic high temperature resisting sealing rings are arranged in the two annular grooves, the two annular convex ridges are connected through a hoop, and the hoop is provided with clamping grooves with the shape matched with the shape of the annular convex ridges. The connecting device for the high-temperature gas connecting pipeline solves the technical problems that an existing high-temperature gas connecting pipeline is complex in connection and a connecting device is poor in leakproofness.
Description
Technical field
The utility model relates to a kind of connecting pipeline, especially relates to a kind of connection set for high-temperature gas connecting pipeline.
Background technique
At present, the Placement of pipeline mainly contains that flange connects and two kinds of clip connecteds, and because flange connects very heavyly, the installing/dismounting of bolt is all very inconvenient, and therefore current connecting pipeline is used clip connected more and more.Clip connected mainly contains seal ring, clip and lock bolt three parts and forms, the seal ring that is positioned at internal layer is placed in the outside of connected piece, and with link on the groove of rolling in advance match, then buckle clip in the outside of seal ring, then by bolton.Because the gas temperature in high-temperature gas connecting pipeline is higher, for example, more than the high energy to 600 of engine exhaust temperature ℃, the sealing rubber ring of common clip can coking or sintering under long-time high temperature, thereby cause sealing variation, affect the Security of motor.
Model utility content
Technical problem to be solved in the utility model is: a kind of connection set for high-temperature gas connecting pipeline is provided, has solved existing high-temperature gas connecting pipeline and connected technical problem complicated, connection set poor sealing.
For solving the problems of the technologies described above, the technical solution of the utility model is: for the connection set of high-temperature gas connecting pipeline, comprise two connecting tubes that are docking together, on the outer circumferential face of two described connecting tube adjacent end portions, be equipped with convex annular distracted, the inner peripheral surface of two described connecting tube adjacent end portions is provided with annular groove, described in two, in annular groove, be provided with an elasticity high-temperature resistant seal ring, described in two, convex annular is distracted passes through a clip connected, between two opening ends of described clip, by lock bolt, connect, described clip has the draw-in groove suitable with the stupefied shape of described convex annular.
Preferably, described in two, the distracted outer rim of convex annular is provided with annular male cone (strobilus masculinus), and the draw-in groove inner peripheral surface of described clip is provided with the annular inner conical surface suitable with described annular male cone (strobilus masculinus).
Preferably, described elasticity high-temperature resistant seal ring is annular steel seal ring.
Preferably, described annular steel seal ring has opening.
Adopted technique scheme, the beneficial effects of the utility model are: on the outer circumferential face due to two connecting tube adjacent end portions of this connection set, be equipped with convex annular distracted, the inner peripheral surface of two connecting tube adjacent end portions is provided with annular groove, two convex annular are distracted passes through a clip connected, can play self-locking function, be provided with an elasticity high-temperature resistant seal ring in two annular grooves, seal washer adopts exotic material, can bear high temperature, guarantee the reliability of high temperature lower sealing device.
Because the distracted outer rim of two convex annular is provided with annular male cone (strobilus masculinus), the draw-in groove inner peripheral surface of clip is provided with annular inner conical surface, and annular inner conical surface and annular male cone (strobilus masculinus) are suitable, play the effect of secondary seal.
Because elasticity high-temperature resistant seal ring is the annular steel seal ring with opening, can design different-diameter, be applicable to the high-temperature gas connecting pipeline of different tube diameters.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the utility model embodiment's parts explosion;
Wherein: 1, connecting tube; 2, convex annular is distracted; 3, annular groove; 4, clip; 5, lock bolt; 6, annular steel seal ring; 7, annular male cone (strobilus masculinus); 8, annular inner conical surface.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Fig. 1 and Fig. 2 are common, connection set for high-temperature gas connecting pipeline, comprise two connecting tubes that are docking together 1, on the outer circumferential face of two connecting tube 1 adjacent end portions, be equipped with convex annular distracted 2, the inner peripheral surface of two connecting tube 1 adjacent end portions is provided with annular groove 3, in two annular grooves 3, being provided with elasticity high-temperature resistant seal ring two convex annular distracted 2 connects by a clip 4, between two opening ends of clip 4, by lock bolt 5, connect, tighten the lock bolt 5 of clip 4, can play self-locking function, clip 4 has the draw-in groove suitable with stupefied 2 shapes of convex annular.
In the present embodiment, described elasticity high-temperature resistant seal ring is the annular steel seal ring 6 with opening, can bear high temperature, guarantees the reliability of high temperature lower sealing device, can design different-diameter, is applicable to the high-temperature gas connecting pipeline of different tube diameters.
The outer rim of two convex annular distracted 2 is provided with annular male cone (strobilus masculinus) 7, and the draw-in groove inner peripheral surface of clip 4 is provided with the annular inner conical surface 8 suitable with annular male cone (strobilus masculinus) 7, plays the effect of secondary seal.
High-temperature gas connecting pipeline connection set of the present utility model is particularly suitable for using in the link of engine exhaust pipe.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
