Abstract
The utility model discloses a reverse vortex type siphoning roof drain, which comprises a siphoning roof drain base plate, a pressing ring and a reverse vortex diversion cover, wherein the reverse vortex diversion cover is fixedly arranged at the upper edge of the siphoning roof drain base plate; the pressing ring is arranged between the siphoning roof drain base plate and the reverse vortex diversion cover; top blades are circumferentially arranged on the top of the reverse vortex diversion cover; and bottom blades distributed uniformly are obliquely arranged at the bottom of the reverse vortex diversion cover in the peripheral direction. The siphoning roof drain has an extremely strong reverse vortex function, and can well prevent air from being brought into the whole system through water flow at the inlet of the roof drain; when the water level in the front of the drain is raised to a certain degree, a water seal is formed and completely protects the whole system from air, and rainwater submerges and overflows to a drainage pipe steadily; and the siphoning roof drain furthest reduces the water accumulation depth of a gutter so that the rainwater load borne by a roof is reduced to minimum, and the rated flow of the roof drain is improved at the same time.
Description
Technical field
The utility model relates to a kind of roofing siphon drainge system, relates in particular to a kind of anti-eddy current type siphon roof drain that is applied to roofing, subway and some important building roofs of each big workshop factory building.
Background technology
In the market the supply the hydrocone type roof drain of a great variety, cut both ways; Existing roof drain is simple in structure and perfect inadequately, and the speed that produces siphonage under the different rainfall charge for remittance conditions also differs, and existing roof drain sucks roof drain together with aqueous vapor, and siphon effect is relatively poor.
The utility model content
The purpose of the utility model is to solve the problems of the prior art, provide a kind of through change rainwater at the fluidised form and the depth of immersion of water inlet, make it not produce the roof drain of vertical shaft vortex.
The technical scheme of the utility model is: a kind of anti-eddy current type siphon roof drain; Comprise siphon roof drain chassis, pressure ring and anti-eddy current kuppe; Said anti-eddy current kuppe is fixedly set in upper edge, said siphon roof drain chassis; Said pressure ring is arranged between siphon roof drain chassis and the anti-eddy current kuppe, circumferentially is provided with top vane at the top of said anti-eddy current kuppe, and the outer circumferentially tilting in its bottom is provided with equally distributed bottom blade.
Said bottom blade compartment is distributed in the bottom of anti-eddy current kuppe.
Said bottom blade angle of inclination with respect to the horizontal plane is 15 °～75 °.
Rotatable the arranging of said bottom blade dextrorotation, the equal Right deviation of its each bottom blade.
The utlity model has extremely strong anti-eddy current function; Can prevent well that air from bringing whole system into through the current of roof drain entrance; And when water level is elevated to a certain degree before bucket, forms water seal and intercept the entering of air fully, and make rainwater flood earial drainage reposefully to get into gutter; The utility model has reduced the depth of accumulated water of gutter to greatest extent, and the rainwater load that roofing is born is reduced to minimum, has improved the metered flow of roof drain simultaneously.
Description of drawings
Fig. 1 is the structural representation of the structure siphon roof drain of the utility model.
The specific embodiment
Understand for technological means, technical characterictic, utility model purpose and the technique effect that the utility model is realized is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
As shown in Figure 1; The anti-eddy current type siphon roof drain of the utility model comprises siphon roof drain chassis 1, pressure ring 2 and anti-eddy current kuppe 3; Anti-eddy current kuppe 3 is fixedly installed on the siphon roof drain chassis 1 through securing members such as screws, and pressure ring 2 is arranged on the upper edge on siphon roof drain chassis 1, circumferentially is provided with top vane 31 outside the top of anti-eddy current kuppe 3; The outer circumferentially tilting in bottom be provided with equally distributed bottom blade 32; Bottom blade 32 compartments are distributed in the bottom of anti-eddy current kuppe 3, and bottom blade 32 angle of inclination with respect to the horizontal plane is 15 °～75 °, i.e. rotatable the arranging of bottom blade 32 dextrorotations; The Right deviation angle of its each bottom blade 32 is 15 °～75 °, and rainwater screws in the roof drain through bottom blade 32.
Rule of thumb formula is confirmed the minimum depth of immersion of roof drain:
h
C＝(VF
1/4+F
1/2)/2
In the formula, h
CFor minimum depth of immersion, V are that admission section flow velocity, F are the admission section area.
Change fluidised form and the depth of immersion of rainwater through the utility model, make it reach minimum depth of immersion, make it not produce the vertical shaft vortex, destroy the negative pressure in the pipeline to avoid sucking air, and then reach the good result that the roof drain aqueous vapor is separated at water inlet.
Being merely the utility model preferred embodiment in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to the technological category of the utility model.
Claims (4)
