Abstract
The utility model relates to a compound sealing ring for hermetically connecting a double-wall winding pipe. The compound sealing ring comprises tube body water swelling rubber rings, connecting rubber belts and nozzle water swelling rubber rings which are sequentially connected into a whole; at least one water swelling rubber rings projecting outwards is arranged on each tube body water swelling rubber ring; a water swelling rubber ring shrinking inwards is arranged each the nozzle water swelling rubber ring. The compound sealing ring provided by the utility model is used for hermetically connecting socket type pipes; during the connection and installation processes of the pipes, the water swelling rubber rings can not only connect the pipes in socket manner, at the same time, but also the water swelling rubber rings can seal the joints at the nozzles; the sealing manner has a double protecting function; water resistance and zero leakage of the pipes are ensured, so that the production and the construction installation processes are greatly simplified.
Description
Technical field
The utility model relates to Sealing, particularly a kind of composite sealing ring for the binary wall twisting and pipe that is tightly connected.
Background technique
In order to substitute traditional waste pipe, emerge a large amount of structured wall plastic waste pipes, common are bellows, riffled tube and binary wall twisting and pipe, wherein with the most rationally safety of the structure of binary wall twisting and pipe.But extrude because the production of binary wall twisting and pipe adopts, winding, welding procedure, cannot can online production spigot and socket type tubing as other adopt structure-wall pipe materials that production technology produces.Although binary wall twisting and pipe is the most rational structured wall popes, Placement is but restricting promoting the use of binary wall twisting and pipe.Patent CN201902752 has reported a kind of water swelling rubber ring of the bimodal F type connecting for binary wall twisting and pipe socket joint.The technological scheme of this patent is: a kind of water swelling rubber ring, comprise water swelling rubber ring body, be provided with the first outwardly stop ring in one end of water swelling rubber ring body, be provided with the second outwardly stop ring in the intermediate portion of water swelling rubber ring body.Patent in implementation process, near first, second stop ring of first need to burn-oning the mouth of pipe.Because welding cannot be realized automatically by equipment completely, must beat fixed stop ring by craft.On the one hand, stable owing to beating the bad control of power, stop ring is fixing not firm, in follow-up transport or using process, may come off, on the other hand, the bad assurance of directivity of beating, there is not parallel or rugged phenomenon in first, second stop ring, so that can cause water leakage phenomenon from middle the extruding of twice stop ring after rubber ring imbibition.Like this, complex operation, labor intensity are greatly, finished product rework rate is high, time-consuming, cost is high, and sealing leak preventing effect is difficult for ensureing.
Model utility content
The purpose of this utility model, exactly in order to address the above problem, provides a kind of composite sealing ring for the binary wall twisting and pipe that is tightly connected.
In order to achieve the above object, the utility model has adopted following technological scheme: a kind of composite sealing ring for the binary wall twisting and pipe that is tightly connected, comprises body water swelling rubber ring, connection rubber tape and mouth of pipe water swelling rubber ring that order is connected; Described body water swelling rubber ring is provided with at least one outwardly hydro-expansive rubber ring, and described mouth of pipe water swelling rubber ring is provided with the hydro-expansive rubber ring inwardly takeing in.
The utility model, owing to having adopted above technological scheme, makes it compared with prior art, has following advantage and disadvantage:
1, adopt composite sealing ring of the present utility model, make binary wall twisting and pipe in process of production, without retaining strip is installed, simplified widely production procedure again;
2, binary wall twisting and pipe connection is more convenient, only need put according to different tube diameters size the composite sealing ring of dimension;
3, use bellmouth and the composite sealing ring of the present utility model with certain length, jointly bring into play seal action by body water swelling rubber ring and mouth of pipe water swelling rubber ring, duplicate protection pipeline sealing.
Brief description of the drawings
Fig. 1 is the sectional structure schematic diagram of the utility model composite sealing ring.
Fig. 2 is the use view in the utility model.
Embodiment
Referring to Fig. 1, coordinate referring to Fig. 2, the composite sealing ring 1 for the binary wall twisting and pipe that is tightly connected of the present utility model, comprises body water swelling rubber ring 12, connection rubber tape 13 and mouth of pipe water swelling rubber ring 14 that order is connected.Body water swelling rubber ring 12 is provided with at least one outwardly hydro-expansive rubber ring, and in the present embodiment, outwardly hydro-expansive rubber ring is two, and one of them is arranged on the outer end of composite sealing ring.Mouth of pipe water swelling rubber ring 14 is provided with the hydro-expansive rubber ring inwardly takeing in, and the hydro-expansive rubber ring that this inwardly takes in is arranged on the inner of composite sealing ring.
Above-mentioned connection rubber tape is that non-water-swellable connects rubber tape.
Use state of the present utility model as shown in Figure 2, in the time carrying out socket joint installation, is enclosed within composite sealing ring 1 at the socket end of a tubing 2, carries out socket joint installation to another root with the female end of caliber pipe material 3.In the process of socket joint, under the effect of female end gradient enlarging frictional force, there is yield deformation in body water swelling rubber ring part, and socket joint installs rear water-swellable elasticity recovery occurs again, thereby reach the object of hermetic seal.Meanwhile, mouth of pipe water swelling rubber ring part is enclosed within mouth of pipe place, in socket joint process, is tightly clipped between the port of two tubing 2 and 3, after mouth of pipe water swelling rubber ring part water-swellable, seals up up hill and dale mouth of pipe joint.
Shown in Fig. 1, Fig. 2,2,3 is tubing, and 4 is bellmouth.
Claims (1)
1. the composite sealing ring for the binary wall twisting and pipe that is tightly connected, it is characterized in that: comprise body water swelling rubber ring, connection rubber tape and mouth of pipe water swelling rubber ring that order is connected: described body water swelling rubber ring is provided with at least one outwardly hydro-expansive rubber ring, and described mouth of pipe water swelling rubber ring is provided with the hydro-expansive rubber ring inwardly takeing in.
