TH10691A3 - Roof drainage device - Google Patents

Abstract

New Request Update 1/9/2016 Traditional rainwater drainage often suffers from debris clogging the drainage equipment. Drainage from the roof is not timely until it may cause flooding of the roof and rain gutters that may cause Possible damage One of them is caused by a vortex of water inside the ventilator and there is air. Residuals inside the drainage device, preventing water from fully passing through the rainwater.The invention is a roof drainage device installed over a rainwater pipe that is assembled with a flow control plate. Installed above the inlet of the rainwater pipe and Scope is a leveled outlet opening to connect the fluid path to the receiving pipe. Such rain The flow control pad has a number of grooves on its lower surface for Forcing a linear flow and reducing the swirl of water passing through the flow control plate in a form of fabrication. The invention also provided holes for ventilation that Residue under the flow control plate Makes it possible to increase the speed of the water from the suction of the device Siphon drainage helps reduce the clogging problem in the rain sewer. In another form Of invention This drainage device also provides a path for channel height adjustment. Open the outlet of the drainage device to help increase the efficiency of draining. And also protect Large debris that cannot be drained in the pipe. This makes it possible to prevent blockages in the pipes.
