Preferably, also comprise a flange, described flange is arranged at the effluent pipe mouth place on roof drain chassis.
Preferably, the top circumference of described kuppe is provided with top vane, bottom it, outer circumferential tilting is provided with equally distributed bottom blade; Described bottom blade compartment is distributed in the bottom of kuppe, and described bottom blade angle of inclination is with respect to the horizontal plane 85 °.
The present invention has the function such as gas-water separation, anti-eddy current.Before its roof drain, the depth of water can effectively control, and when before roof drain, stable level reaches design head, form siphon full packages pressure current in system, steady flow is good, overall performance is superior.Exhaust grille in the present invention is in rainfall, rainwater enters roof drain by blade, lower blade, when roofing charge for remittance reach a certain height, blocks air enters from the external world and eliminates turbulent state simultaneously by the anti-vortex device in roof drain, makes rainwater flood earial drainage reposefully and enters gutter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is decomposing schematic representation of the present invention.
Detailed description of the invention
The technological means realized to make the present invention, technical characteristic, goal of the invention and technique effect are easy to understand, and below in conjunction with concrete diagram, set forth the present invention further.
Be the anti-eddy current type siphon rainwater head 1 of one of the present invention as shown in Figure 1, 2, comprise roof drain chassis 11, be located at the roof drain chassis tail pipe 12 of lower end, described roof drain chassis 11 and be placed in the kuppe 13 at top, described roof drain chassis 11.The end of the roof drain tail pipe 12 in the present invention can direct socket connection pipeline; Also an adpting flange can be set, be connected with metallic conduit by seal.
The present invention also comprises exhaust grille 14, mounting bracket 15 and filtering grid 16.Exhaust grille 14 in the present invention is located at the top of described kuppe 13; Described mounting bracket 15 is located at the top of roof drain chassis 11 water inlet pipe mouth, and described filtering grid 16 is placed in the inside of described mounting bracket 15.
The top circumference of the kuppe 13 in the present invention is provided with top vane (not shown), and bottom it, outer circumferential tilting is provided with equally distributed bottom blade 131; Described bottom blade 131 compartment is distributed in the bottom of kuppe 13, and described bottom blade 131 angle of inclination is with respect to the horizontal plane 85 °.
The lower blade 143 that exhaust grille 14 in the present invention comprises disk body 141, is located at the blade 142 at disk body 141 top and is located at bottom described disk body 141.Blade 142 angle of inclination with respect to the horizontal plane of the exhaust grille 14 in the present invention is 30 ° ~ 90 °, and preferably the angle of inclination of blade 142 is 60 ° in the present invention.Lower blade 143 angle of inclination with respect to the horizontal plane of exhaust grille 14 is 30 ° ~ 90 °, and the angle of inclination of lower blade 143 is preferably 90 °.When current inject exhaust grille 14, effectively air can be discharged, and be unlikely to water, gas to be mixed in roof drain chassis 11, affect speed and the effect of draining.
Exhaust grille 14 in the present invention is connected with described kuppe 13 is dismountable by bolt 144 or male and female dop, is connected by dismountable mode, is convenient to the foreign material clearing up long term accumulation in roof drain chassis 11, is beneficial to dredging pipeline, facilitates periodic cleaning.
