Abstract
The invention provides a wear-resistant wall pipe leakage prevention mechanism. The wear-resistant wall pipe leakage prevention mechanism comprises a sleeve base, a first conical seal ring, a second conical seal ring and a pressing plate, wherein the upper portion of the sleeve base is provided with an outward flanging, the first conical seal ring is arranged in the sleeve base, the second conical seal ring is matched with the first conical seal ring reversely, and the pressing plate presses the second conical seal ring tightly. A sealing pressure pad is arranged on the lower side of the flanging. The pressing plate and the sleeve base are fixed through connecting screws. Uncovering screws are arranged between the pressing plate and the sleeve base. The pressing plate is provided with counterbore through holes for mounting the connecting screws and the uncovering screws. The wear-resistant wall pipe leakage prevention mechanism is reasonable in structural design and presses and seals a central pipe through the first seal ring and the second seal ring. Meanwhile, an outer sleeve is sealed through the pressure pad on the sleeve base, and the sealing effect is good. The uncovering screws are arranged between the pressing plate and the sleeve base, dismantling of the pressing plate is facilitated, and separation of the first seal ring and the second seal ring is facilitated. The disadvantages that damaged seal rings are not likely to dismantle and hard to replace are avoided.
Description
Technical field
The invention belongs to waterproofing work technical field, more particularly, to a kind of wear-resisting poling leakage preventing mechanism.
Background technology
Industry and civil buildings floor gap, have substantial amounts of water pipe and pass through.Existing water pipe installation method mostly is the building layer through pipe for first installing external diameter on concrete floor more than water pipe, water pipe passes through floor again inside Jing building layer through pipe, exist for tackling the reserved gap of water pipe thermal expansion between water pipe and building layer through pipe, but this gap often brings the problem along the downward leak of pipe outer wall, so as to impact to the orthobiosiss of production, work and resident.Wear-resisting poling leakage preventing mechanism of the prior art, sealing are poor, especially in practical operation, will beat glass cement, waste time and energy between water pipe and sleeve pipe.For avoiding water pipe from interfering with other structures and space-saving consideration, floor sleeve pipe typically can all be arranged on the corner in room, so, limited to the working place for beating glass cement, it is difficult to glass cement is uniformly clamp-oned the gap between water pipe and sleeve pipe, in addition, between sleeve pipe and poling, it is not provided with sealing structure, if the water yield there was not poling top, still there is the situation of downward leak.Therefore, need a kind of good airproof performance badly, and be easy to the wear-resisting poling leakage preventing mechanism constructed.
The content of the invention
The invention problem to be solved is to provide a kind of wear-resisting poling leakage preventing mechanism, solves the defect of wear-resisting poling leakage preventing mechanism sealing difference in prior art, and easily, using effect is good for installation operation.
For solving above-mentioned technical problem, what the technical scheme of the invention was realized in：
A kind of wear-resisting poling leakage preventing mechanism, has the first conical seal ring being provided with the sleeve pedestal of outside flanging, sleeve pedestal and the first conical seal ring to overturn the second conical seal ring of cooperation and compress the pressing plate of the second conical seal ring including upper bands；Sealed pressure pad is provided with the downside of the flanging；Fixed by attachment screw between the pressing plate and the sleeve pedestal, and be provided with opening screw between the two, the inside and outside wall of first sealing ring and the second sealing ring is coated with wearing layer.
Further, the tapered structure in the sleeve pedestal lower end.
Further, the symmetrical setting two of the opening screw.
Further, by positioning finger setting between second sealing ring and the pressing plate.
The invention has the advantages and positive effects that：
1）Reasonable in design, is compressed at center seal pipe by the first sealing ring and the second sealing ring, while by the pressure pad sealing hermetically sealed case pipe in sleeve pedestal, good sealing effect.
2）Opening screw is provided between pressing plate and the sleeve pedestal, facilitates pressing plate to dismantle, be easy to the first sealing ring and the second sealing ring to separate, it is to avoid think that sealing ring is not easy to remove after damaging, the drawbacks of change difficult.
3）Sleeve pedestal lower end be cone structure, with guide effect, facilitate sleeve pedestal wear with building sleeve pipe.
4）Pressing plate is provided with and is respectively used to install the heavy platform through hole of the band of the attachment screw and the opening screw, the nut of attachment screw and opening screw can be submerged in heavy platform, it is ensured that nut is not interfered with outside, save space, and elegant in appearance.

Specific embodiment
It should be noted that in the case where not colliding, the feature in embodiment and embodiment in the invention can be mutually combined.
Below in conjunction with the accompanying drawings the specific embodiment of the invention is elaborated.
A kind of wear-resisting poling leakage preventing mechanism, as shown in figure 1, having the first conical seal ring 3 being provided with the sleeve pedestal 2 of outside flanging 1, sleeve pedestal 2, and 3 reverse the second conical seal ring 4 for coordinating of the first conical seal ring, and compressing the pressing plate 5 of the second conical seal ring 4 including upper bands；Sealed pressure pad 6 is provided with the downside of the flanging 1；Fixed by attachment screw 7 between the pressing plate 5 and the sleeve pedestal 2, and be provided with opening screw 8 between the two.It is pointed out that the second sealing ring 4 can be fixed together using screw with pressing plate 5, during dismounting, by removing pressing plate 5, related second sealing ring 4 is taken down together, is convenient for changing.
Opening screw 8 is provided between pressing plate 5 and sleeve pedestal 2, facilitates the dismounting of pressing plate 5, be easy to the first sealing ring 3 and the second sealing ring 4 to separate, it is to avoid think that sealing ring is not easy to remove after damaging, the drawbacks of change difficult.
Wherein, the inside and outside wall of first sealing ring 3 and the second sealing ring 4 is coated with wearing layer, durable in use, is difficult wear damage.
Wherein, the pressing plate 5 is provided with and is respectively used to install the heavy platform through hole of the band of the attachment screw 7 and the opening screw 8.The nut of attachment screw 7 and opening screw 8 can be submerged in heavy platform, it is ensured that nut is not interfered with outside, save space, and it is elegant in appearance.
Sleeve pedestal 2 is worn with building sleeve pipe for convenience, and 2 lower end of the sleeve pedestal is processed as cone structure, makes cone structure part play guide effect.
Wherein, 6 section of the sealed pressure pad is L-shaped, and its both sides is close to 1 lower surface of the flanging and 2 outer wall of sleeve pedestal respectively, it is ensured that the sealing between sleeve pedestal 2 and building sleeve pipe.It should be noted that one side lower end chamfering that sealed pressure pad 6 is close to 2 outer wall of sleeve pedestal, plays guide effect, conveniently wear with building sleeve pipe, it is to avoid scratch damage.
Generally, the symmetrical setting two of opening screw 8, so, when with 8 jack-up pressing plate 5 of opening screw, while screwing the two symmetrical opening screws 8, it is ensured that 5 uniform force of pressing plate, the second sealing ring 4 is more convenient for separating with the first sealing ring 3.
Wherein, positioned by alignment pin 9 between second sealing ring 4 and the pressing plate 5, positioning is reliable, it is to avoid the second sealing ring 4 occurs play during installation or use.
The invention reasonable in design, is compressed at center seal pipe by the first sealing ring and the second sealing ring, while by the pressure pad sealing hermetically sealed case pipe in sleeve pedestal, good sealing effect.
