Description
Technical field
The utility model relates to PE Manifold technology field, specifically a kind of external sealed formula PE pipe connection.
Background technique
In urban construction, PE pipe is widely used in fuel gas transmission and water network construction, though have lightweight compared with steel pipe, cast iron tube, and the advantages such as corrosion-resistant, easy construction, life-span are long.At present, PE pipe gas ductwork, to the network of rivers in the inner seal ring technology that adopts more solve sealing problem between body.
The PE pipe Placement of said structure, because material is not good or construction wrong easily causes leakage hidden danger.Leak once occur, must rush to repair fast and effectively, the machining needs of inner seal ring technology to sealing configuration is high, and user cost is high, install complicated, and sealing effect is poor.
Model utility content
Technical assignment of the present utility model provides a kind of external sealed formula PE pipe connection for above-mentioned deficiency of the prior art, this kind of PE pipe connection can realize the external sealed linkage structure of PE pipe, efficiently solve PE pipe joint easily to occur leaking, complicated problem of speedily carrying out rescue work of constructing.
The utility model solves the technological scheme that its technical problem adopts: this kind of external sealed formula PE pipe connection, and it is characterized in that, its structure comprises the rubber seal of an annular, and the two ends of described seal ring are set in the port position that need connect PE pipe;
Described seal ring outer surface is provided with at least 3 lock ring steel bands, and described lock ring steel band and seal ring are fixed by the screw on lock ring steel band;
The outer surface of described PE tube opening is provided with axially locating boss, and described axially locating boss is right-angled trapezium;
The end face of described PE tube opening is provided with radial location boss, and described radial location boss is rectangle.
Preferably, described axially locating boss quantity is at least 4.
Preferably, described radial location boss quantity is at least 2.
Preferably, the internal diameter of described seal ring and the external diameter interference fit of PE pipe.
The utility model has following outstanding beneficial effect:
1, because its structure comprises the rubber seal of an annular, the two ends of described seal ring are set in the port position that need connect PE pipe, therefore, during use, the alternative traditional inner seal ring structure of exterior seal ring structure, reduce the machining requirements of seal ring, improve the quality after the connection of PE pipe.
2, owing to being provided with at least 3 lock ring steel bands outside described seal ring, described lock ring steel band and seal ring are fixed by the screw on lock ring steel band, and therefore, during use, lock ring steel band anatomical connectivity is reliable, simple to operate, improves the working efficiency that PE pipe connects.
3, because the outside of described PE tube opening is provided with axially locating boss, described axially locating boss is right-angled trapezium; The bottom of described PE tube opening is provided with radial location boss, and described radial location boss is rectangle, and therefore, during use, the boss structure on PE tube wall can effectively prevent leaking of transportation of substances, and seal ring can be prevented to be separated with PE pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be Fig. 1 partly cut open structural representation.
Description of reference numerals: 1PE manages, 2 seal rings, 3 lock ring steel bands, 4 screws, 5 axially locating boss, 6 radial location boss.
Embodiment
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
As shown in Figure 1 and Figure 2, this kind of external sealed formula PE pipe connection, its structure comprises the rubber seal 2 of an annular, and the two ends of described seal ring 2 are set in the port position that need connect PE pipe 1.During use, the alternative traditional inner seal ring structure of exterior seal ring 2 structure, reduces the machining requirements of seal ring 2, installs easily, improves the quality after PE pipe 1 connection.
In above-described embodiment, concrete, described seal ring 2 outer surface is provided with at least 3 lock ring steel bands 3, and described lock ring steel band 3 is fixed by the screw 4 on lock ring steel band 3 with seal ring 2.During use, lock ring steel band 3 anatomical connectivity is reliable, simple to operate, is convenient to inspection and the installation of PE pipe 1, improves the working efficiency that PE pipe 1 connects.
In above-described embodiment, concrete, the outer surface of described PE pipe 1 port is provided with axially locating boss 5, and described axially locating boss 5 is right-angled trapezium; The end face of described PE tube opening is provided with radial location boss 6, and described radial location boss is rectangle.During use, the boss structure on PE pipe 1 tube wall can effectively prevent leaking of transportation of substances, and seal ring 2 can be prevented to be separated with PE pipe 1.
In above-described embodiment, more specifically, described axially locating boss 5 quantity is at least 4.During use, axially locating boss 5 is by can effectively prevent leaking of transportation of substances with fitting tightly of seal ring 2.
In above-described embodiment, more specifically, described radial location boss 6 quantity is at least 2.During use, radial location boss 6 is by can hinder transportation of substances to ooze out in two PE pipe 1 joints with fitting tightly of seal ring 2 and cause a hidden trouble.
In above-described embodiment, more specifically, the internal diameter of described seal ring 2 and the external diameter interference fit of PE pipe 1.During use, there is certain precompression between seal ring 2 and PE pipe 1, after preventing transportation of substances from pressurizeing, seal ring 2 expands, and causes the phenomenon occurring leaking.
A kind of external sealed formula PE pipe connection of the present utility model, by PE pipe, seal ring, the cooperatively interacting of lock ring steel band, achieving this kind of external sealed formula PE pipe connection uses exterior seal ring to connect the function of PE pipe, efficiently solve PE pipe joint easily to occur leaking, construction is speedily carried out rescue work complicated problem, it is simple to operate, improves working efficiency, ensure that the quality after the connection of PE pipe.
The above, be only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model.Any those of ordinary skill in the art; do not departing under technical solutions of the utility model ambit; technology contents described above all can be utilized to make many possible variations and modification to technical solutions of the utility model; or the Equivalent embodiments being revised as equivalent variations therefore; every content not departing from technical solutions of the utility model; according to technology of the present utility model to any change amendment made for any of the above embodiments, equivalent variations and modification, all belong to the protection domain of the technical program.
