Abstract

The utility model discloses a bent-surface connecting pipe clamp which comprises a pair of semi-circular hoops which are buckled at an opening of a pipeline, the outer sides of the buckling surface of the semi-circular hoops are respectively provided with a lug plate, an oval hole which is arranged along the axial direction of the pipeline is respectively formed in the lug plates, simultaneously, the inner surface of each semi-circular hoop is provided with a groove, a sealing ring with a C-shaped section is arranged in the groove, and the buckling surfaces of the semi-circular hoops are in Z shape or L shape. In the utility model, fine adjustment to the dimension of the hoop can be realized by the bent-surface connection mode, so that the bent-surface connecting pipe clamp can be suitable for the pipeline groove with the depth having small fluctuation, the phenomenon of pipe dropping can be avoided, simultaneously, the edge of the sealing ring is in a step shape, the linear sealing of the sealing ring and the pipeline groove can be realized, the original surface sealing can be replaced, and the whole sealing effect is better.

Description

Zig zag plane connects pipe clamp

Technical field

The utility model relates to the pipe joint technical field, relates in particular to a kind of zig zag plane and connects pipe clamp.

Background technique

At present, the main clamp band type that adopts connected (also claiming groove type to connect) during pipeline when pipeline construction connected, this Placement is passed through pipeline groove, the cooperation of seal ring and clip realizes the effect of being tightly connected, be characterized in simple to operate, easy to maintenance, in using, actual production played very big effect, but also there is the defective of some aspect in this Placement: because the degree of depth of pipeline groove must just can play good sealing effect with the size of clip is suitable in installation process, but the degree of depth of pipeline groove small variation can occur unavoidably aborning, and the buckling surface of clip is the plane, its size is changeless, cross in the pipeline groove degree of depth like this and just can make the effect that seals between pipeline groove and the clip bad when dark, the phenomenon that under high pressure, occurs taking off pipe easily.

The model utility content

Technical problem to be solved in the utility model is: provide a kind of zig zag plane to connect pipe clamp, this Connection Card can make the clip size realize small variation, thereby adapts to the degree of depth of pipeline groove, the phenomenon of avoiding occurring taking off pipe under high pressure.

For solving the problems of the technologies described above, the technical solution of the utility model is: zig zag plane connects pipe clamp, comprise a pair of semicircle clip that is fastened on pipeline mouth of pipe place, the outside of described semicircle clip buckling surface is provided with otic placode, have on the described otic placode along the slotted eye of the axial setting of pipeline, the internal surface of described semicircle clip is provided with groove, be provided with the cross section in the described groove and be the seal ring of " C " shape, the buckling surface of described semicircle clip be " Z " shape or " L " shape.

As a preferred implementation, the edge of described " C " shape seal ring is stepped.

After having adopted technique scheme, the beneficial effects of the utility model are: owing to be that the semicircle clip on plane changes over buckling surface and is with buckling surface " Z " shape or " L " shape, then in installation process, can realize small relative displacement between two semicircle clips, thereby realized the fine setting of clip size, make it can be suitable with the pipeline groove of different depth, realize better seal, the phenomenon of having avoided under high pressure, occurring taking off pipe.

Because it is stepped that the edge of " C " shape seal ring is set to, then after installation, seal ring can be realized the linear sealing with pipeline, guarantees the phenomenon that can not occur leaking, than before face seal had better sealing.

Fig. 5 is the local enlarged diagram at I place among Fig. 3;

Among the figure: 1. semicircle clip; 2. otic placode; 3. slotted eye; 4. " Z " shape buckling surface; 5. groove; 6. ladder; 7. " C " shape seal ring.

Embodiment

As shown in Figure 1, the structural representation that connects pipe clamp for the utility model zig zag plane, this connection pipe clamp comprises a pair of semicircle clip 1 that is fastened on pipeline mouth of pipe place, certainly, not shown described pipeline, and the central axis of the axis of described pipeline and semicircle clip 1 should be located along the same line.

As shown in Figure 2, be the sectional view behind the A-A direction place to go seal ring among Fig. 1, the buckling surface of described semicircle clip 1 is " Z " shape, certainly, herein buckling surface be " L " shape also can, like this, described two semicircle clips 1 can be realized the fine setting of clip size by relatively moving between described " Z " shape buckling surface 4, make its degree of depth that adapts to pipeline groove, realize the better seal effect.

The internal surface of described semicircle clip 1 has groove 5, be provided with the seal ring 7 of cross section in the described groove 5 for " C " shape, as Fig. 3 and shown in Figure 5, be respectively sectional view and its local enlarged diagram of described " C " shape seal ring 7, the edge of described " C " shape seal ring 7 is provided with ladder 6, shown in Fig. 5 two place's ladders 6 are arranged, like this, when matching with pipeline, stair-stepping edge can realize linear sealing, guarantee the phenomenon that can not occur leaking, than before face seal had better sealing.

As shown in Figure 4, plan view for semicircle clip 1, the buckling surface outside at described semicircle clip 1 is provided with otic placode 2, have on the described otic placode 2 along the slotted eye 3 of the axial setting of pipeline, during installation, penetrate bolt in described slotted eye 3, use the nut just can two semicircle clips 1 are fixing, the effect of slotted eye 3 herein be in order to make things convenient for moving of bolt when regulating semicircle clip 1.

In a word, the utility model utilizes the zig zag plane ways of connecting can realize the adjusting that the clip size is small, thereby make it adapt to the pipeline groove that the degree of depth has minor fluctuations, avoided taking off the generation of pipe phenomenon, the edge of seal ring is stepped simultaneously, can realize the linear sealing of seal ring and pipeline groove, replace original face seal, make integral sealing effect better.

The utility model is not limited to above-mentioned embodiment, and all are based on technical conceive of the present utility model, and the structural improvement of having done all falls among the protection domain of the present utility model.
