Connecting piece of vertical swirl water drainage pipe in caisson type restroom

Abstract

The invention discloses a connecting piece of a vertical swirl and water drainage pipe in a caisson type restroom. A nut cover, a plastic gasket, a pipe tightening rubber ring, a vertical pipe seat at the layer, a tee joint, a dust remover, a waist seat body, a swirl pipe body and a vertical pipe seat at the lower layer are arranged sequentially from the top to the bottom end, wherein a small cylindrical lug boss of the dust remover is fixed with a dust remover positioning hole of the waist seat body in a glue joint manner; the waist cylindrical surface of the waist seat body is fixed with the lower glue joint surface of the vertical pipe seat at the lower layer in a glue joint manner; the middle cylindrical surface and the upper glue joint surface of the tee joint are respectively fixed with the waist cylindrical surface of the waist seat body and the upper cylindrical surface of the vertical pipe seat at the layer in a glue joint manner; the pipe tightening rubber ring and the plastic gasket are arranged at the upper end of the inner part of the vertical pipe seat at the layer and are pressed and fixed through the nut cover; the swirl pipe body is fixedly arranged in the vertical pipe seat at the lower layer. The connecting piece has the advantages of simple structure, scientific design and reasonable arrangement. Besides, the problem of the secondary water drainage for the leakage of the deposited water in the caisson during the water drainage at the same layer is solved, and the connecting piece can be widely applied to water drainage pipeline systems of industrial buildings and residential buildings.

Description

technical field [0001] The invention relates to the field of building drainage systems, in particular to a swirl drainage standpipe connector for a caisson type toilet. Background technique [0002] For toilet drainage in industrial or residential buildings, the traditional method is to use compartment drainage. The horizontal water pipe must pass through the floor and hang horizontally on the ceiling of the next floor of the household to connect with the standpipe. This not only invades the space of other residents, but also affects the beauty of the bathroom interior. In particular, each sanitary appliance must be installed with "P" and "S" traps to achieve water seals, and these water seals are the most prone to blockage and leakage. , and the maintenance is extremely inconvenient. Once leakage will cause unnecessary property loss to the residents, such a drainage system has been gradually eliminated. The Ministry of Construction has always emphasized drainage at the sam...
