Rainwater pipe flat-suction-preventing pipe fitting
Technical Field
The invention relates to a drainage device, in particular to a flat suction preventing pipe fitting of a rainwater pipe.
Background
In residential construction, the pipe plays a crucial role in drainage, both in the transport of normal water and in the drainage of rainwater. Rainwater often extrudes certain air in the pipe fitting discharge process, leads to the pressure imbalance. Generally, on arranging of our residential building, arranging of pipe fitting can form drainage system, consider the reason of raining, can arrange rainwater drainage system, to rainwater drainage system, especially high-rise rainwater drainage system, the rainwater pipe often can appear and inhale flat phenomenon, this is because at heavy rain, torrential rain weather, under the operating mode that the rainwater pipe flows fully, the air is all discharged by the rainwater in the rainwater pipe, and at this moment, the rainwater descends because of gravity fast, makes intraductal formation negative pressure state to lead to the rainwater pipe to be inhaled flat.
Generally speaking, the existing means for solving the problem of flattening suction is to increase the wall thickness of the rainwater pipe, and although the operation solves the problem of flattening suction to a certain extent, the operation belongs to a method for treating symptoms and not treating the root causes, the problem that the pipe is flattened due to negative pressure cannot be fundamentally solved, and certain cost is increased.
Moreover, on arranging to tubular product, tubular product generally all is that the segmentation is connected and is arranged, need to apply and connect the pipe fitting and just can link up the downspout and play a role, if adopt one section tubular product to carry out arranging of rainwater drainage system, then do not have actual operability and reality. The connection of tubular product and tubular product generally adopts the telescopic joint in the rainwater drainage system, and its connected mode with the downspout is comparatively complicated, is unfavorable for convenient effectual linking.
