Overflow-proof same-layer water drainage riser connecting piece

Abstract

The invention provides an overflow-proof same-layer water drainage riser connecting piece. The overflow-proof same-layer water drainage riser connecting piece comprises a collection tank, a riser connecting pipe penetrating the collection tank, a collection tank top cover and a water seal tank, wherein the riser connecting pipe is provided with a water outlet in the collection tank, the top tank wall of the water seal tank is formed by the top cover, a water inlet and a waterspout are arranged on the wall of the water seal tank, a tank body water seal partition plate is arranged in the water seal tank, the top of the tank body water seal partition plate is articulated with the inner side of the top wall of the water seal tank, the bottom end of the tank body water seal partition plate is higher than the bottom of the water seal tank, and the lowest position of the waterspout is not lower than the bottom end of the tank body water seal partition plate and not lower than the lowest position of the water outlet; and when the bottom end of the tank body water seal partition plate presses against the wall of the water seal tank, the water seal tank can be divided into two tank bodies which are not communicated with each other, and the water inlet and the waterspout are respectively arranged on the two tank bodies which are not communicated with each other. The device has the advantages of being scientific in design, reliable in properties and capable of preventing odor return of the water seal.

Description

technical field [0001] The invention relates to a building water supply and drainage device, in particular to an anti-backflow same-layer drainage standpipe connector. Background technique [0002] In the field of building water supply and drainage, the riser connector is usually pre-buried in the part where the drainage riser passes through the floor, so as to connect the current floor and the lower floor drainpipe, and avoid the leakage problem caused by the accumulation of water in the subsidence area that cannot be discharged; but in use, In order to avoid leakage, the waterproof layer is usually turned up along the pipeline and a water-blocking table is set up, which makes the indoor floor layout look messy, unsightly, and inconvenient for decoration, and the accumulated water on the ground cannot be drained directly, resulting in seepage in the subsidence area. Leakage hidden danger; secondly, in the same-floor drainage scheme of the sunken toilet, because the drainage...

[0002] In the field of building water supply and drainage, the riser connector is usually pre-buried in the part where the drainage riser passes through the floor, so as to connect the current floor and the lower floor drainpipe, and avoid the leakage problem caused by the accumulation of water in the subsidence area that cannot be discharged; but in use, In order to avoid leakage, the waterproof layer is usually turned up along the pipeline and a water-blocking table is set up, which makes the indoor floor layout look messy, unsightly, and inconvenient for decoration, and the accumulated water on the ground cannot be drained directly, resulting in seepage in the subsidence area. Leakage hidden danger; secondly, in the same-floor drainage scheme of the sunken toilet, because the drainage horizontal pipe trap is buried in the floor interlayer, the cleaning opening of the drainage horizontal pipe is useless and cannot be blocked and cleared. Once blocked, it will be used Again, the drains of floor drains, bathtubs, wash basins, mop pools, etc. are all provided with separate water seals, and if one drain seal dries up, it will cause indoor odor and endanger health.
