Anti-overflow single-riser drainage system
The invention discloses an anti-overflow single-riser drainage system. The anti-overflow single-riser drainage system comprises drainage risers, a stack vent cap, drainage three-way components, a first-floor drainage elbow and a first-floor horizontal drainage pipe. The drainage riser on each floor of a building is provided with one three-way component, and the drainage three-way component on eachfloor is connected with a horizontal connection pipe of the corresponding floor. Each drainage three-way component comprises a drainage tee joint and a diaphragm inner sleeve, wherein an inflow portis formed in the upper end of the diaphragm inner sleeve, an outflow port is formed in the lower end of the diaphragm inner sleeve, the outflow port is fixedly connected with part of the portion around a lower connector of the drainage tee joint, the inflow port is fixedly connected with the portion around an upper connector of the drainage tee joint, and a horizontal connector on the drainage teejoint is connected with the corresponding horizontal connection pipe. By means of the system, violent intersection collision and splashing diffusion of two water streams are avoided, hydraulic conditions are improved, positive-pressure reverse overflow and negative-pressure suction are eliminated, the system is beneficial to maintaining a stable flow state and reducing water flow impact noises, and improvement of the drainage capacity of the risers and the indoor environment muting level is facilitated.
本发明公开了一种可防溢单立管排水系统，包括排水立管、伸顶通气帽、排水三通组件、首层排出弯管和首层水平排出管；建筑各层的排水立管上均设置有一个排水三通组件，每一层上的排水三通组件均与相应楼层的水平接入管连接；排水三通组件由排水三通和隔膜内套组成，隔膜内套上端设置有入流口，下端设置有出流口，出流口与排水三通的下接口周边部位局部固定连接，入流口与排水三通的上接口周边部位固定连接，排水三通上的水平接口与水平接入管连接。本发明避免了两股水流发生激烈的交汇冲撞及飞溅扩散，改善了水力条件，消除正压反溢及负压抽吸，有利于维持稳定的流态及降低水流冲击噪音，有助于提升立管的排水能力及室内环境静音水平。
