Quick drainage type anti-backflow floor drain
The invention relates to a quick drainage type anti-backflow floor drain. The quick drainage type anti-backflow floor drain comprises a prefabricated pipeline connector, a water retaining barrel, a water storage device, an upper shell, a lifting sleeve, a first water inlet, a second water inlet, a third water inlet, a plurality of stop rods, a buoyancy rod, a first buoyancy ball and a second buoyancy ball. The prefabricated pipeline connector comprises a connecting body and an inner shell, the inner shell is arranged in the connecting body, and the first water inlet and the second water inletare formed in the lifting sleeve. According to the quick drainage type anti-backflow floor drain, when small-flow sewage is drained, impurities can be blocked in the upper shell to prevent the impurities from blocking a pipeline; and when the water flow is large and water is not drained in time, sewage enters from the second water inlet and the third water inlet and flows out from multiple two-wayopenings, so that large-flow water drainage is achieved. When water return occurs in the pipeline, the stop rods stop the lifting sleeve from further ascending, the first buoyancy ball blocks a waterdrainage hole, the lower section of the lifting sleeve is in sealing fit with the inner end of an inner support, and therefore, water is prevented from overflowing from the upper portion of the quickdrainage type anti-backflow floor drain.
本发明涉及一种快排式防反水地漏，包括预制管道连接器、挡水筒、储水器、上壳体、升降套、第一进水口、第二进水口、第三进水口、多个止挡杆、浮力杆、第一浮力球、第二浮力球。预制管道连接器包括连接体和内壳体，内壳体设置于连接体内，升降套上设置有第一进水口和第二进水口。本发明的一种快排式防反水地漏，当排泄小流量污水时，可将杂质阻挡在上壳体内，防止杂质阻塞管道；当水流量较大、排水不及时时，污水从第二进水口和第三进水口中进入，从多个双向开口中流出，实现大流量排水。当管道出现反水时，止挡杆阻挡升降套的进一步上升，且第一浮力球将泄水孔封堵，升降套的下区段与内支架内端密封配合，阻断水从快排式反防水地漏的上方溢出。
