Negative-pressure-resistant siphon roof drain
The negative-pressure-resistant siphon roof drain comprises a siphon roof drain body, a bottom-layer flow guide plate, a drain cover and an interlayer flow guide plate, a bottom-layer water inlet is formed in the bottom of the siphon roof drain body, the bottom-layer flow guide plate is arranged at the bottom-layer water inlet, a garbage grating is further arranged at the bottom-layer water inlet, the garbage grating is arranged below the bottom-layer flow guide plate, and the interlayer flow guide plate is arranged below the bottom-layer flow guide plate. The hopper cover is arranged at the upper end of the siphon rain hopper, the interlayer flow guide plate is arranged in the siphon rain hopper and between the garbage grating and the bottom layer flow guide plate, a flow discharge hole is formed in the center of the interlayer flow guide plate, an air flow discharge plate is arranged in the flow discharge hole, and a separation stand column is fixedly arranged below the center of the hopper cover. The invention belongs to the technical field of siphon drainage, and particularly provides a negative-pressure-resistant siphon roof drain which is characterized in that when a garbage grating is blocked by garbage, a pressure spring is gradually compressed, an air discharge plate is pushed downwards, a sealing effect is lost, air quickly enters a siphon system, and a siphon pipeline is prevented from being flattened and damaged by suction.
本发明公开了耐负压虹吸雨水斗，包括虹吸雨斗、底层导流板、斗盖和隔层导流板，所述虹吸雨斗底部设有底层进水口，所述底层导流板设于底层进水口处，所述底层进水口处还设有垃圾格栅，所述垃圾格栅设于底层导流板下方，所述斗盖设于虹吸雨斗上端，所述隔层导流板设于虹吸雨斗内，所述隔层导流板设于垃圾格栅、底层导流板之间，所述隔层导流板中心处设有卸流孔，所述卸流孔内设有空气卸流板，所述斗盖中心处下方固设有分隔立柱。本发明属于虹吸排水技术领域，具体是提供了一种垃圾格栅被垃圾堵塞时，压力弹簧逐渐压缩，空气卸流板向下推进，失去密封效果，使空气快速进入虹吸系统，避免了虹吸管道被吸扁破坏的耐负压虹吸雨水斗。
