Abstract
The utility model discloses a groove connection structure for fire protection pipelines. The groove connection structure comprises pipelines, sealing rubber rings and clamp hoops, wherein the inner wall of each clamp hoop close to two ends are respectively provided with annular bosses, an annular installation groove is formed between the two annular bosses, the outer wall of ends of the pipelines are provided with grooves matched with the annular bosses, corrosion prevention layers are arranged on end faces of the pipelines, the sealing rubber rings are installed in the annular installation grooves of the clamp hoops, the annular bosses at one ends of the clamp hoops are clamped in the grooves at one ends of the pipelines, the annular bosses at the other ends of the clamp hoops are clamped in the grooves at the other ends of the pipelines, and the clamp hoops are in sealing fit with the outer walls of the pipelines which are in butt joint with the clamp hoops through the sealing rubber rings. The corrosion prevention layers arranged on end faces of the pipelines are corrosion-prevention waterproof paint so as to prevent ends of the pipelines from being directly exposed in liquid media to cause corrosion and improve corrosion resistance of fire protection pipelines.
Description
Technical field
The utility model relates to the pipeline connection technology field, is specifically related to a kind of groove linkage structure of fire protection pipeline.
Background technique
Existing fire protection pipeline adopts hot galvanizing welded steel pipe or seamless hot galvanized steel pipe usually; Earlier hot dip galvanizing pipe length is as required cut off with pipe cutting machine during installation; Galvanized pipe after will cutting off again is formed by connecting from beginning to end, and the general groove that adopts is connected between pipe and the pipe.It is that utilization is rolled, grooving equipment goes out groove at the tube end rolling cut that groove connects, and is linked to be a kind of Placement of pipe network through the groove pipe fitting of band O-ring seal.Owing to on-the-spot layout needs, most pipelines all will cut and perforate, and these operations have destroyed the zinc coat of pipeline, and existing construction process is not done any preservative treatment to region of interest, and it contacts with the interior inactive liquid medium of pipe for a long time, very easily is corroded.
The model utility content
To the above-mentioned deficiency that exists in the existing technology, the utility model provides the groove linkage structure of the good fire protection pipeline of a kind of antiseptic property.
To achieve these goals, the technological scheme of the utility model employing is following:
A kind of groove linkage structure of fire protection pipeline comprises pipeline, O-ring seal and clip, it is characterized in that, the inwall of said clip is respectively equipped with annular boss near two ends, forms annular mounting groove between two annular boss; The outer wall of said pipe end is provided with the groove that matches with annular boss, and the end face of said pipeline is provided with anticorrosive coat; Said O-ring seal is installed in the annular mounting groove of clip; The annular boss of said clip one end is stuck in the groove of a pipe end; The annular boss of the clip the other end is stuck in the groove of another pipe end, and clip is sealed and matched with the outer wall that docks pipeline through O-ring seal.
As a kind of preferred version of the utility model, said pipeline is a hot dip galvanizing pipe.
As the another kind of preferred version of the utility model, said anticorrosive coat is zinc coat or anticorrosion waterproof enamelled coating.
As another preferred version of the utility model, the thickness of said anticorrosive coat is 0.05 ~ 0.2mm.
Compare existing technology, the utlity model has following beneficial effect:
1, the utility model is provided with anticorrosive coat through the end at pipeline, and this anticorrosive coat is zinc coat or anticorrosion waterproof enamelled coating, has avoided pipe end is directly exposed to the corrosion that causes in the liquid medium, has improved the Corrosion Protection of fire protection pipeline.
2, near two ends annular boss is set respectively through inwall at clip; The annular mounting groove that is formed for installing O-ring seal between two annular boss; The groove that matches with annular boss in the outer wall setting of pipe end;, quick for installation, easy, reliable between pipeline and the pipeline through the sealing of O-ring seal and locked clip device, and have the ability of flexibility and antidetonation, anti-convergent-divergent.
Description of drawings
Fig. 1 is the structural representation of model utility.
Wherein, 1 is pipeline, and 2 is clip, and 3 is anticorrosive coat, and 4 is O-ring seal, and 5 is annular boss.
Embodiment
Below in conjunction with embodiment the utility model is described further.
Referring to Fig. 1: the groove linkage structure of fire protection pipeline comprises pipeline 1, O-ring seal 4 and clip 2.Pipeline 1 can adopt galvanized pipe, line plastic-steel tube or steel-plastic composite pipe, and the outer wall in pipeline 1 end is provided with groove.Clip 2 adopts general rigidity clip; The inwall of clip 2 is provided with the annular boss 5 that matches with groove; Annular boss 5 is two, is used for matching with the groove of two pipelines 1 respectively the annular mounting groove that is formed for installing O-ring seal 4 between two annular boss 5.
During installation, earlier O-ring seal 4 is enclosed within the end of two pipelines 1, covers the slit between two pipelines 1, and guarantee the dead in line of two pipelines 1; Annular boss 5 with clip 2 snaps in the groove of two pipelines 1 again, and O-ring seal 4 is installed in the annular mounting groove; With bolt clip 2 is fastenedly connected then, O-ring seal 4 is closely contacted with clip 2 inwalls with pipeline 1 outer wall, add that pipeline 1 inner fluid to producing back-pressure in the O-ring seal 4, makes pipeline 1 joint obtain multi-level sealing.
In order to improve the Corrosion Protection of pipeline 1; Avoid port with pipeline 1 to be directly exposed in the liquid medium and cause corrosion; Be provided with anticorrosive coat 3 in the end of pipeline 1, this anticorrosive coat 3 is coated on the end face of pipeline 1 for adopting anticorrosion underwater paint, and the thickness of anticorrosive coat 3 is 0.05 ~ 0.2mm.
Need to prove at last; Above embodiment is only in order to technological scheme but not the restriction technologies scheme of explanation the utility model; Although the claimant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technological schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
Claims (4)
