Abstract
The utility model discloses a double-wall corrugated pipe seal ring, which comprises a seal ring body, wherein the section of the annular outer wall of the seal ring body is in the shape of saw teeth matching with corrugation on a double-wall corrugated pipe, sections of two sides of the seal ring body are combined to form a dovetail-shaped structure, a barb structure is arranged on the lower side of the dovetail-shaped structure, two sides of the seal ring body are both provided with annular grooves, and the annular grooves are both arranged on the lower side of the barb structure. The double-wall corrugated pipe seal ring is simple in structure and low in cost, and contact area between the consistent surface structure of the seal ring and a pipe is expanded to form multi-layered seal effect, thereby increasing sealing property effectively. Further, the double-wall corrugated pipe seal ring is reliably connected with the pipe and can not be overturned.
Description
Technical field:
The utility model belongs to tubing accessory technical field, relates in particular to a kind of double-wall corrugated pipe seal ring.
Background technique:
Double-wall corrugated pipe is a kind of structural plastic wall pipe, mainly is to be applied to blowdown, draining field.Tubing connects the general ductility seal ring socket joint that adopts and connects, because tubing is distortion of connection mouth end and dimensional changes in transportation and storage process, and PE material pipe deforming behind the construction earthing, existing seal ring is generally circle or wedge shape, its elastic module is limited, causes the part of connection the problem of leaking and overturning often to occur inserting.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, provides a kind of and avoids leaking and the double-wall corrugated pipe seal ring of turning problem.
The utility model is achieved through the following technical solutions:
A kind of double-wall corrugated pipe seal ring, include the sealing circle body, it is characterized in that: the flexuose of the annular outer wall cross section of described sealing circle body for cooperating with ripple on the double-wall corrugated pipe, sealing circle body both sides side cross-section constitutes swallowtail-shaped structure, described swallowtail-shaped structure downside is the hangnail structure, described sealing circle body all has annular groove on the bi-side, and described annular groove all is positioned at described hangnail structure underside.
The utility model has increased the elastic strain space of sealing circle body, laciniation has increased sealing of the present utility model greatly, the distortion that swallowtail-shaped structure causes when pipeline is connected be connected the gap that deflection causes and have good regulating action, the hangnail structure can effectively prevent the generation of conventional seals circle infiltration situation, annular groove can have been economized more material, the cost of Jiang Diing greatly under the situation that does not influence sealing effect.
The utility model has the advantages that:
The utility model is simple in structure, cost is low, and the surface structure design that it is unified and tube contacts face increase, and forms the stage construction sealing effect, effectively raises sealing, and the utility model is connected with pipeline reliably, flop phenomenon can not take place.
Description of drawings:
Accompanying drawing is a schematic cross-section of the present utility model.
Embodiment:
A kind of double-wall corrugated pipe seal ring, include sealing circle body 5, the annular outer wall cross section 1 of described sealing circle body 5 is the flexuose that cooperates with ripple on the double-wall corrugated pipe, sealing circle body 5 both sides side cross-section 2 constitute swallowtail-shaped structure, described swallowtail-shaped structure downside is a hangnail structure 3, described sealing circle body all has annular groove 4 on 5 bi-side, and described annular groove 4 all is positioned at described hangnail structure 3 downsides.
