Siphon rainwater system

Siphon rainwater system


  • The roof drain and piping layout is flexible
  • The system can be accompanied with multiple roof drains,with the quantity being unlimited.
  • The reduction of the stand pipe quantity and reduction of the pipe diameter would correspondingly reduce the quantity of the outdoor inspection shafts and reduce the ground excavation.
  • With the reduction of the system engineering quantity and the adoption of the pressure-bearing pipes, the service life of the system could exceed 50 years
  • With the high-speed tight flow of the rainwater inside the pipe, it could realize the self-purification function.
  • The non-gradient installation of the hanging pipes would facilitate the full use of the architectural space.




Essential Conditions of Siphon Formation


In respect of the siphonic rainwater drainage and collection systems, the siphon action shall be formed by full use of the energy produced from the altitude difference between the roof and the ground that is carefully calculated by use of the “Bernoulli” equation, in which the system would rapidly discharge the rainwater in the full flow state and provide convenience for the subsequent rainwater collection.



Siphon Roof Drain

As the core product of the system, it adopts the unique backward eddy current device, in which the rainwater becomes evenly dispersed before it flows into the drain bucket, so as to destroy the conditions to form eddies and isolate the air from entering, when the system would present the full pipe flow state. The siphon roof drain could reach the full flow state in the condition of the smaller water depth before the drain, so as to effectively reduce the ponding depth of the roof (roof gutter) and reduce the roof load.



Hydraulic Calculation (Node Balance)

Since the siphon system rapidly discharges the rainwater in the full flow state, the design must ensure the consistency of the water discharge of all the roof drains in the system; and at the same time, the inflow water loss for each transition section from the roof drain to the outlet must be accurately calculated, so as to ensure the consistency of the water discharge state of each roof drain.



Stand Pipe Height (Gravitational Potential Energy)

As the core product of the system, it adopts the unique backward eddy current device, in which the rainwater becomes evenly dispersed before it flows into the drain bucket, so as to destroy the conditions to form eddies and isolate the air from entering, when the system would present the full pipe flow state. The siphon roof drain could reach the full flow state in the condition of the smaller water depth before the drain, so as to effectively reduce the ponding depth of the roof (roof gutter) and reduce the roof load.





Siphon Roof Drain System



Fairwater

Made of silicon-aluminum alloy material, it is applicable for various different environments. The fairwater grating separation distance of continuous improvement could not only ensure the inflow water flow, but also prevent large sundries from entering into the system.



Rectifier

With the silicon-aluminum alloy material and the unique backward eddy current design, it could make the rainwater smoothly enter into the System.



Waterproof pressure plate/mounting plate

With the silicon-aluminum alloy material and the unique backward eddy current design, it could make the rainwater smoothly enter into the System.



Sink drain bucket

Made of the stainless steel material, the rectifier shall be put inside the sink drain bucket, so as to effectively reduce the ponding depth of the roof (roof gutter).



Outlet pipe

Such outlet tail pipes as of different materials should be selected according to the difference of the pipes to be used. There are HDPE tail pipe, stainless steel tail pipe and groove-connected stainless steel tail pipe.

YG65 13~24 L/s Φ300mm
YG80 24~30 L/s Φ300mm
YG100 30~42 L/s Φ300mm

Pipes & Fittings



The high density polyethylene pipe is made of polyethylene as the main raw material, with the addition of a handfwwul of such materials as of the antioxidant, ultraviolet-resistant absorbent and pigment. As the most common pipes used for the siphonic rainwater drainage system, it has such characteristics as of light weight, convenience for transportation and construction, and perfect sealing performance.



  • The pipes and fittings are complete in specifications, with theModel and Specification: De15~De400, and the Pressure Bearing Grade: PN3.2~PN20, which could satisfyvarious engineering demands
  • The pipes used for the siphonic rainwater drainage system need to satisfy the requirements of the production standards, in which the pipes is made of PE100 raw material and pipe fittings are made of PE80 raw material, with the pipe pressure bearing grade being greater than PN6 and all the pipes being subject to the 0.09 Mparesistant negative pressure test.
  • The pipelines shall be of strong toughness, aging resistance, impact resistance, wear resistance, acid-base resistance and corrosion resistance.
  • The pipes have a long service life, which could exceed 50 years.
  • The light weight of the HDPE pipe could make it convenient for transportation, construction and installation, and the adoption of the hot-melting and electric-melting connection could make it of perfect tightness.
  • Before the delivery, the pipes have gone through the special technology processing to make the pipeline linear expansion coefficient less than1.5%.
  • With the small modulus of elasticity, the pipes can absorb the water flow noise inside the pipe.






HDPE Pipe Fixed System


The fixed system has been developed in allusion to the requirements for the special installation of the HDPE pipes applied to the siphon system. The inside of the hanging pipes of the siphonic rainwater drainage system presents the negative state. In order to avoid the air leakage of the system, the system would set up no expansion joint. Tidelion would use the “fixed installation” to limit the stretch mode of the pipeline, in which the axial stress caused by the temperature change of the HDPE pipes would directly be transmitted to the parallelly-installed square steel pipes through the fixed points of the fixed pipe clamp. Through the practical experience in the rainwater drainage system, the maximum working temperature difference of the fixed system can reach 50℃



  • Since the square steel pipe has less suspension points with the building structure, it is widely applied to various new-type structures.
  • The expansion amount of HDPE pipes is translated into the axial stress through the fixed pipe clamps with no expansion joint being used, so as to avoid the air leakage hidden trouble of the expansion joints.
  • After the surface of the fittings goes through the hot galvanizing treatment, they are even more beautiful and durable than the traditional field-fabricated hooks. more durable.
  • All the fittings are made in the factory, so what to do on the construction site would only need to make the simple assembly thereof
