Abstract
The utility model discloses a special sealing washer of sewer line, including the elastic rubber body, the compound anti -corrosion body of the external portion of water inflation rubber is met to the compound water inflation rubber body of meeting of the external portion of elastic rubber, is provided with the several fluting that equals the spacing distance on the anti -corrosion body. The utility model discloses add the elastic rubber body, can be according to sewer line's structural feature, be embedded into the slot of pipeline in a flexible way, the installation of being convenient for, again because its self elasticity, the outside chance water inflation rubber body can effectively be supported to sealing strip installation back, strengthens holistic leakproofness, meeting the water inflation rubber body and having the water of chance inflation, a sealed function of the automatic healing compensation of inflation that absorbs water repeatedly, the fluting of sewage medium on through the anti -corrosion body soaks meets the water inflation rubber body, meets the volume expansion of water inflation rubber, plays main sealed effect, the anti -corrosion body plays fixed the design and meets the effect of the water inflation rubber body, avoids meeting the water inflation rubber body and corrodes through long -time sewage that locally peeling off appears in the back, the seal failure problem of the rotten initiation of colloid.
Description
Technical field
The utility model relates to a kind of nonmetal seal ring, particularly relates to a kind of sewage conduct special sealing ring.
Background technique
At present, what the sewage conduct great majority in Urban Buried Pipeline Network engineering adopted is high polymer elastic rubber weather strip, rubber-type Stamping Steel Ribbon product also exists product and not easily installs, the long-time problem using poor sealing after installing, and the medium composition complexity owing to circulating in sewage conduct, more serious to the corrosion of rubber weather strip, the working life of such Stamping Steel Ribbon is also shortened greatly, for underground engineering, change extremely inconvenience after Stamping Steel Ribbon damages, the rubber weather strip that therefore existing underground engineering uses urgently improves.
Model utility content
The utility model is in order to overcome the deficiencies in the prior art, and active response national underground pipework 3P calls, and develops a kind of good sealing effect, is exclusively used in the extended life seal bar of underground sewer engineering.
The utility model is achieved through the following technical solutions: sewage conduct special sealing ring, comprise elastic rubbery body, be compounded with hydro-expansive rubber body in elastic caoutchouc external body, hydro-expansive rubber external body is compounded with anti-corrosion body, anti-corrosion body is provided with several flutings of equal intervals distance.
Further, described elastic rubbery body and hydro-expansive rubber body are trapezoid shaped.
Further, the thickness of anti-corrosion body is no more than 3mm.
Owing to have employed said structure, the utility model compared with prior art, there is following beneficial effect: by setting up elastic rubbery body, sealing bar according to the structural feature of sewage conduct, can be embedded in the groove of pipeline neatly, be convenient to install, again due to the spring function feature of himself, after Stamping Steel Ribbon is installed, can the hydro-expansive rubber body of effective supports outer, strengthen the sealing of entirety; Hydro-expansive rubber body has water-swellable, repeatedly to absorb water the automatically healing compensation sealing function that repeatedly expands, and wastewater media soaks into hydro-expansive rubber body by the fluting on the anti-corrosion body of outermost surface, and main seal action is played in hydro-expansive rubber volumetric expansion; Outermost anti-corrosion body plays fixing sizing hydro-expansive rubber body, avoids hydro-expansive rubber body after long corrosion in water, occur the peeling off of local, the seal failure problem that colloid goes bad and then causes.
Accompanying drawing explanation
Fig. 1 is the utility model schematic cross-section.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
As shown in Figure 1, sewage conduct special sealing ring, comprises elastic rubbery body 1, and the outside of elastic rubbery body 1 is compounded with hydro-expansive rubber body 2, and hydro-expansive rubber body 2 outside is compounded with anti-corrosion body 3, anti-corrosion body 3 is provided with several flutings 30 of equal intervals distance.Fluting 30 covers a circle around anti-corrosion body 3.
In the present embodiment, elastic rubbery body 1 and hydro-expansive rubber body 2 are in trapezoid shaped.
In the present embodiment, the thickness of anti-corrosion body 3 is no more than 3mm, and anti-corrosion body 3 is for the protection of hydro-expansive rubber body 2.
When this Stamping Steel Ribbon uses, what first make dimension according to the size of sewage conduct meets Stamping Steel Ribbon, the Cross section Design trapezoidal shape of Stamping Steel Ribbon is beneficial to installation, section area 10-20%mm larger than sewage conduct groove area, object is the inherent difficult drop-off of groove utilizing the spring function of elastic rubbery body 1 and be tightly supported on sewage conduct.Seal ring described in the present embodiment is by setting up elastic rubbery body 1, make sealing bar can according to the structural feature of sewage conduct, be embedded into neatly in the groove of pipeline, be convenient to install, again due to the spring function feature of himself, after Stamping Steel Ribbon is installed, can the hydro-expansive rubber body 2 of effective supports outer, strengthen the sealing of entirety; Hydro-expansive rubber body 2 has water-swellable, repeatedly to absorb water the automatically healing compensation sealing function that repeatedly expands, wastewater media soaks into hydro-expansive rubber body by the fluting 30 on the anti-corrosion body 3 of outermost surface, hydro-expansive rubber body 2 expands, and plays main seal action; Outermost anti-corrosion body 3 plays fixing sizing hydro-expansive rubber body 2, avoids hydro-expansive rubber body 2 after long corrosion in water, occur the peeling off of local, the seal failure problem that colloid goes bad and then causes.
Stamping Steel Ribbon described in the present embodiment more conventional Stamping Steel Ribbon improves 400% ~ 550% working life, can be widely used in underground engineering, in the sewage conduct of especially underground.
More than describing is to explanation of the present utility model, and not to restriction of the present utility model, the utility model limited range is see claim, and when without prejudice to the utility model basic conception, the utility model can do the amendment of other form.
