Description

Downpipe leak-proof connector

technical field

The utility model relates to a drainage and drainage device, in particular to a leak-proof connection piece for a downpipe installed inside a floor to prevent water seepage from the ceiling.

Background technique

At present, when installing sewer pipes in buildings, for example, there are floor drains installed on the ground surface in bathrooms and kitchens. The floor drains are fixedly connected to the cement floor. Because the cement will shrink during the curing process, resulting in cement and sewer pipes. If there is a small amount of gap, if there is water, it will leak down along the gap. For this reason, someone has designed a kind of patent (patent application number: 01211321.2) by name: " anti-seepage floor drain collar ", and it is an annular collar, and annular collar has an outer edge, and outer edge The diameter is larger than the diameter of the downpipe. When in use, it is installed at the connection between the downpipe port and the floor drain. The collar and the outer edge are mainly used to block the gap between the cement and the downpipe. Although this design can play the effect of sealing and waterproofing to a certain extent, because the design only blocks the gap to prevent water from leaking from the gap, after many years of use, long-term corrosion will still make the collar and There are tiny gaps between the cement, and the water seeps down along the downpipe under the action of gravity, dripping all the way to the rooms of the residents downstairs, affecting the daily life of the residents downstairs.

Utility model content

The utility model mainly solves the technical problems in the prior art that long-term corrosion will cause tiny gaps between the collar and the cement, and water will leak downward along the sewer pipe, affecting the daily life of the residents downstairs. The utility model provides a leak-proof connector for a downpipe that is provided with a leak-proof cover and a water return hole on the downpipe to prevent water seepage from the ceiling.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a leak-proof connector for a sewer pipe, including a sewer pipe, characterized in that: the sewer pipe is sleeved with a leak-proof cover, and the sewer pipe The side wall is also provided with a water return hole, and the water return hole is located inside the leak-proof cover. The leak-proof cover is sleeved on the downpipe, and the leak-proof cover and the downpipe are integrated into one structure or the two are fixed together without leaving any gaps. When water leaks down the downpipe, the leak-proof cover can collect the water When the height of the water exceeds the return hole, the water will flow back into the downpipe from the return hole, thereby preventing It prevents the occurrence of water leakage along the sewer pipe to the ceiling downstairs.

As a preference, the said downpipe is also sleeved with a baffle, and the baffle is arranged in the leak-proof cover and above the water return hole. The sewer pipe above the backwater hole is provided with a dividing plate, and the dividing plate can be made of water seepage material. The setting of the dividing plate helps the utility model to prevent the cement from blocking the backwater hole during construction and installation.

Preferably, the separator is provided with water leakage holes. The dividing plate can also be made of impermeable material, and the dividing plate is provided with leaking holes to facilitate downward water seepage.

Preferably, the leak-proof cover is coaxially arranged with the downpipe. The leak-proof cover and the downpipe are coaxially arranged, which is beneficial for the leak-proof cover to gather the water leaked around the downwater pipe.

Preferably, the leak-proof cover is funnel-shaped. The leak-proof cover is funnel-shaped, and can also be inverted circular truncated or bowl-shaped. Such a leak-proof cover is conducive to gathering the water leaked around the downpipe, and finally flows back into the downpipe from the return hole.

Preferably, the partition is circular, and its outer diameter is smaller than the diameter of the top surface of the leakproof cover. The separator is circular, and its outer diameter is smaller than the diameter of the top surface of the leak-proof cover, which can ensure that the separator can be stacked in the leak-proof cover, saving materials and protecting the return hole from being blocked by cement .

Preferably, the angle formed by the return hole and the downpipe is the same as the angle formed by the side of the leakproof cover and the downpipe. The angle formed by the backwater hole and the downpipe is the same as the angle formed by the side of the leak-proof cover and the downpipe, which is beneficial for water to flow back into the downpipe from the backwater hole.

Preferably, the water return hole is arranged at the innermost part of the leakproof cover. The backwater hole is arranged at the innermost part of the leak-proof cover, so that the accumulated water in the leak-proof cover flows from the backwater hole to the downpipe at the first time, and the situation of secondary leakage caused by too much accumulated water will not occur.

Therefore, the utility model has the following characteristics: 1. simple in structure, reasonable in design; Seepage, and then flow back into the water pipe from the backwater hole, the leak-proof effect is better; 3. The water pipe above the backwater hole is covered with a partition, and the cement will not block the backwater hole during construction and installation of the utility model; 4. The backwater hole is located at the lowest point inside the leak-proof cover. The water in the leak-proof cover can flow from the backwater hole to the downpipe at the first time, and there will be no secondary leakage caused by too much water. situation.

Detailed ways

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Embodiment 1: A leak-proof connector for a sewer pipe, comprising a sewer pipe 1 made of corrosion-resistant plastic, a funnel-shaped leak-proof cover 2 sleeved on the sewer pipe 1, and the leak-proof cover 2 is connected to the lower sewer pipe. The water pipe 1 is coaxially arranged, and the leak-proof cover 2 is also made of corrosion-resistant plastic and integrated with the downpipe 1 (see accompanying drawing 1). The side wall of the downpipe 1 is also provided with a backwater hole 3, and the backwater hole 3 is positioned at the inner side of the leak-proof cover 2; The angle formed by hole 3 and downpipe 1 is the same as the angle formed by leakproof cover 2 sides and downpipe 1, which is 45 degrees. The sewer pipe 1 is also covered with a partition 4, the partition 4 is made of water-permeable material, the partition 4 is set in the leak-proof cover 2 and is located above the return hole 3, and the partition 4 is provided with a water leakage hole 5; The partition plate 4 is circular, and its outer diameter is smaller than the top surface diameter of the leak-proof cover 2, and the partition plate 4 is stacked on the inner wall of the leak-proof cover 2 (see accompanying drawing 2).

During use, utilize cement 6 to fix this utility model in the slab of floor, the stagnant water of this floor can seep downwards from gap 7, and anti-leakage cover 2 gathers the stagnant water leaking down around sewer pipe 1 in In the leak-proof cover 2, the water seeps along the leak-proof cover 2 and then seeps through the leak hole 5 on the partition 4, and reaches the bottom of the leak-proof cover 2. , the stagnant water flows directly from the backwater hole 3 into the downpipe 1 (see Figure 3), so that the stagnant water leaking around the downpipe 1 will not leak down again, thereby preventing water from seeping along the downpipe Occurrence of phenomena such as leakage to the ceiling downstairs.
