Embodiment Construction

[0012] The outlet pipe of the siphon rainwater drainage system of the present invention will be further described with reference to the accompanying drawings. Such as figure 1 As shown, the water outlet pipe of the siphon rainwater drainage system includes a pipe body 1 and a water outlet 2 arranged on the pipe body 1 with a diameter larger than the diameter of the pipe body 1. The water outlet 2 is provided with a water outlet 21, and the water outlet 2 It is arranged on the pipe body 1 by welding connection, and a buffer water retaining structure 3 used to prevent the discharged water from damaging the foundation is provided at a distance of 2120 mm to 50 mm from the water outlet. The buffer water retaining structure 3 is set on the water outlet via a bracket 4 On the outer wall of section 2, the buffer water-retaining structure 3 can be set at a distance of 20 mm, 30 mm, 40 mm, or 50 mm from the water outlet 21. For specific installation, please refer to the local precipitati...

Abstract

The invention relates to housing rainwater drainage system accessories, in particular to a water outlet pipe for a siphon rainwater drainage system. According to the water outlet pipe for the siphon rainwater drainage system, provided by the invention, a buffer water retaining structure used for preventing a foundation from being damaged by a drained water flow is arranged at the distance of 20 mm to 50 mm from a water outlet; the water flow drained from the water outlet rushes to the buffer water retaining structure, so that the internal stress of the water flow drained from the water outlet is released; therefore, the foundation is effectively prevented from being damaged by the water flow drained from the water outlet, the service life of the drainage system is prolonged; in addition, a water outlet part is connected with a pipe body by welding, the water outlet part and the pipe body are sealed reliably, and the siphon performance of the water drainage system is improved, so that the water drainage speed of the water drainage system is higher.

Description

Technical field [0001] The invention relates to a house rainwater drainage system fitting, in particular to a siphon rainwater drainage system outlet pipe. Background technique [0002] The siphon rainwater drainage system is widely used due to its fast drainage speed and good drainage effect. [0003] In the prior art, the siphon rainwater drainage uses the siphon principle to drain rainwater on the roof. Therefore, the water flow discharged from the drainage port has a certain pressure during the drainage process, which makes it easy for the water flow discharged from the drainage port to lay the pipe. The foundation is washed out, reducing the service life of the rainwater drainage system. Summary of the invention [0004] The water outlet pipe of the siphon rainwater drainage system provided by the present invention aims to overcome the disadvantages of the prior art that the water discharged from the drainage port is easy to wash the foundation and the drainage system has a sh...
