就H管不同连接位置对双立管排水系统通水性能的影响进行研究,测试采用铸铁管材及配件,通过变换H管位置进行试验。对试验数据进行分析比较后,得出不同H管位置对双立管排水系统通水性能的影响。H管不同安装位置会严重影响三通处的通气状况,其中H管紧靠三通下部时通水效果最为显著。
The influence of different connection positions of H pipes on the water-passing performance of the double-riser drainage system was studied. The cast iron pipes and fittings were used in the test, and the test was conducted by changing the positions of the H pipes. After analyzing and comparing the experimental data, the influence of different H-tube positions on the water-passing performance of the double-riser drainage system was obtained. H tube different installation positions will seriously affect the ventilation at the tee, where the H tube close to the lower part of the pass when the water effect is most significant.
