Abstract

PURPOSE: To provide an indoor drainage piping system, in which a self-sweeping section in the form of a right-angled triangle is provided at the portion where the lower end of a vertical pipe and main horizontal pipe are coupled together, and couplings each having a guide vane are provided at portions where the vertical pipe and horizontal branch pipes are connected together, whereby it is enabled to prevent blow-out and back flow in the piping system with a relatively simple arrangement.
CONSTITUTION: In case of double piping system having a vertical drainage pipe 1 and a ventilation pipe 2 juxtaposed with each other, lower end of drainage pipe 1 and main horizontal pipe 11 are connected at self-sweeping section 12, to which lower end of ventiltation pipe 2 is further connected. Couplings 3 of pipe 1 and ventilation pipe 2 are connected together by connecting tubes 8, and horizontal branch pipes 7 are connected to the couplings 3. Each of these couplings 3 is formed at one side thereof with a channel portion 9 having a sectional area larger than that of the vertical pipe 1 itself so as to cover the end openings of branch pipes 7. Upwardly of branch pipes 7, a guide vane 4 is fixed at an inclination angle of 45°, and a partition plate 6 is provided at the lower end of vane 4 with spacing 13. Further, a tongue 5 is formed at the upper portion of around the end opening of lower branch pipe 7.
