Abstract
The utility model discloses a polyethylene siphon type roof drain which comprises a cowling, a roof drain seat and a drainage tail pipe. The roof drain seat is a hopper-shaped disc body. The drainage tail pipe is arranged at the lower side of a water outlet formed in the center of the hopper-shaped disc body. The cowling comprises a circular-cap-shaped top board, a grating skirt portion, a lower flange ring and an inner cylinder. A boss is coaxially arranged in the center of the upper surface of the circular-cap-shaped top board. Radial guiding ribs and fan-shaped water outlets are arranged on the circumferential portion of the upper surface of the circular-cap-shaped top board. The inner cylinder is arranged in the middle of the lower surface of the circular-cap-shaped top board. The grating skirt portion is arranged on the circumferential portion of the lower surface of the circular-cap-shaped top board. The lower flange ring is arranged on the lower portion of the grating skirt portion and matched with an upper flange ring of the roof drain seat. Connecting through holes are formed in the upper flange ring and the lower flange ring in a spaced mode. According to the polyethylene siphon type roof drain, swirls can not be generated even though rainwater is overmuch so that air can not enter the drainage pipe, siphoning can be formed conveniently, the noise of siphoning can be reduced, and the water drainage effect can be enhanced.
Description
Technical field
The utility model relates to a kind of roof drain for building, is specifically related to a kind of polyethylene hydrocone type roof drain.
Background technology
At present, Chinese large tracts of land building roof, labyrinth roofing constantly increase, and traditional gravity current drainage system against rain originally can not satisfy the existing building designing requirement.Large tracts of land building roof, labyrinth roofing use traditional gravity current drainage system against rain will reach the rain-water drainage amount that norm of construction require, a difficult problem of mainly meeting is as follows: roof drain quantity is too much, the storm-water system discharge capacity is too little, the storm-water system transverse tube is installed the gradient and is had a strong impact on problems such as ceiling is decorated, rain leader downspout quantity is too much, when at the many groups of roofing installation roof drain, certainly will form huge and complicated pipe network under the roofing, occupy the following a large amount of usefull space of roofing, cause unreasonable in the design, and also corresponding increasing considerably of construction costs.
For this reason, people have designed the roof drain of hydrocone type, and this roof drain can address the above problem preferably, but that the roof drain of existing hydrocone type also exists siphon effect is bad, problem such as noise is big.
The utility model content
Based on above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of polyethylene hydrocone type roof drain, the utility model can not form in inside in excessive rainfall yet and revolve nest, the interior no air of gutter is entered, be convenient to the formation of siphon, not only reduce the siphon noise, also strengthened drainage effect.
The technical solution of the utility model is: a kind of polyethylene hydrocone type roof drain, comprise radome fairing, bucket seat and draining tail pipe, described bucket seat is the infundibulate disk body, the center delivery port downside of described infundibulate disk body is provided with the draining tail pipe, wherein: described radome fairing comprises round hat top board, the grid skirt section, lower flange ring and inner core, described round hat cover top surface center is coaxially arranged with boss, described round hat cover top surface perimembranous is provided with radially water conservancy diversion rib and fan-shaped outfall, described inner core is arranged on round hat top board soffit middle part, described grid skirt section is arranged on round hat top board soffit perimembranous, described lower flange ring is arranged on the bottom in grid skirt section, described lower flange ring cooperates with bucket seat upper flange ring, and on described, be arranged at intervals with connecting through hole on the lower flange ring.
Further, be provided with radially deflector in the described infundibulate disk body.
The beneficial effects of the utility model are: owing to designed grid skirt section, inner core and structure such as deflector radially, make hydrocone type roof drain of the present utility model in excessive rainfall, also can not form in inside and revolve nest, the interior no air of gutter is entered, be convenient to the formation of siphon, not only reduce the siphon noise, also strengthened drainage effect.
