Composite ventilation device for drainage stand pipe
The invention relates to the technical field of drainage pipelines, in particular to a composite ventilation device for a drainage vertical pipe. Comprising a pipeline and a composite ventilation module which are communicated with each other; the composite ventilation module comprises a three-way pipe fitting, a short pipe, an air suction valve, a bent pipe, a butterfly valve unit and a top-extending ventilation cap, the three-way pipe fitting is communicated with the pipeline, one end of the short pipe is communicated with the three-way pipe fitting, the other end of the short pipe is provided with the air suction valve, one end of the bent pipe is communicated with the three-way pipe fitting, and the other end of the bent pipe is provided with the top-extending ventilation cap; a butterfly valve unit is arranged on the bent pipe, a top-extending ventilation cap and an air suction valve are combined, a water seal is protected, and stink is prevented from returning into a toilet.
本发明涉及排水管道技术领域，具体涉及一种排水立管复合通气装置；包括管道和复合通气模块，复合通气模块与管道相连通；复合通气模块包括三通管件、短管、吸气阀、弯管、蝶阀单元和伸顶通气帽，三通管件与管道相连通，短管的一端与三通管件相连通，短管的另一端设置有吸气阀，弯管的一端与三通管件相连通，弯管的另一端设置有伸顶通气帽，弯管上设置有蝶阀单元，通过将伸顶通气帽和吸气阀组合，对水封进行保护，避免卫生间内返臭气。
