Anti-negative-pressure drainage system on same floor
The invention belongs to the technical field of drainage on the same floor of a building, and discloses an anti-negative-pressure drainage system on the same floor. The system comprises a drainage vertical pipe and a drainage horizontal pipe, wherein the drainage horizontal pipe is communicated with the drainage vertical pipe through a connecting pipe fitting; the connecting pipe fitting comprisesa straight pipe and a side pipe; the side pipe comprises a pipe body and an opening; an inner thread is arranged on the inner wall of one end, close to the opening, of the pipe body; a sealing layeris arranged on the inner wall of the pipe body from the position of the internal thread towards the direction far away from the opening; and an anti-negative-pressure pipe fitting is arranged on the drainage horizontal pipe. According to the system, the sealing layer is arranged on the inner wall of the side pipe of the connecting pipe fitting, a force transmission rod connected with a fixing ringbelt arranged outside abuts against the sealing layer through the opening, so that the strength of the connecting pipe fitting and the sealing property between the connecting pipe fitting and the drainage horizontal pipe are enhanced, the service life of the drainage system on the same layer is prolonged, the anti-negative-pressure pipe fitting has the effect of being similar to a one-way valve,sewage can not flow in only, sewage and odor in the drainage vertical pipe can be effectively prevented from flowing back into households structurally, and moreover, the system is provided with an access port, and is practical and convenient to use.
本发明属于建筑同层排水技术领域，公开了一种防负压同层排水系统，包括排水竖管、排水横管，排水横管通过连接管件与排水竖管连通，连接管件包括直管和侧管，侧管包括管本体和开口，管本体靠近开口的一端内壁上设有内螺纹；管本体内壁自内螺纹处朝向远离开口的方向设置有密封层；在所述排水横管上设置有防负压管件。本发明通过在连接管件的侧管的内壁设置密封层，外部设置的固定环带连接的传力杆通过开孔抵接在密封层处，增强连接管件的强度以及其与排水横管之间的密封性，延长同层排水系统的使用寿命，防负压管件具有类似单向阀的作用，污水只出不进，结构上即能够有效防止排水立管内的污水、臭气返窜入住户家中，且自带检修口，实用方便。
