Description
Technical field:
The utility model relates to a kind of sunk type siphon roof drain, and it belongs to a kind of launching gear of building, bucket under particularly a kind of rainwater that is used to build roof anti-leak.
Background technology:
Existing building roof drain is made up of columned metal sewer pipe and common anti-leaf cover.When running into heavy rain, water level is very high before the bucket of roof drain, if be directly used in building roof, roof ponding is more.Be subjected to above-mentioned condition restriction, the roof drain that existing flow is bigger can only be used on the building roof of gutter, brings a lot of difficulties for the design of building structure, construction.Because the restriction of existing roof drain structure, normally directly pre-buried to building roof, the working procedure of this fixed form is loaded down with trivial details, is unfavorable for installation and maintenance, and also there is certain problem in its sealing effectiveness.This class roof drain also can produce the whirlpool phenomenon when operation, cause a large amount of air of rainwater doping and import system pipeline, forms the air water two-phase flow, has influenced the drainability of storm-water system greatly.
Summary of the invention:
The purpose of this utility model is to provide a kind of and is directly used in flat roof deck, fixed form is simple, the sunk type siphon roof drain that the sluicing flow is big.
The purpose of this utility model is achieved in that
A kind of sunk type siphon roof drain, it comprises anti-leaf cover, vortex eliminator and bucket body, described anti-leaf cover places the top of described bucket body; It is characterized in that described bucket body is the sunk type bucket body, the inclined-plane that edge, the bottom of described bucket body has a down dip to the middle part; A ponding zone is formed in the bucket body inwall of bucket body and bucket body bottom; The anti-swirl vane of described vortex eliminator and bucket body bottom are close together, and anti-leaf cover directly is connected with bucket body by connector.
Between described anti-leaf cover and bucket body, be provided with a waterproof flange.
Described anti-leaf cover and waterproof flange are monolithic construction.
The top of described bucket body is provided with the connection flanging, is provided with connecting hole on described connection flanging, and the waterproof flange is connected by described connecting hole with bucket body.
The soffit of described waterproof flange is a hackly surface.
Top at described anti-leaf cover is provided with reinforcing rib, and is provided with auxiliary inlet opening between described reinforcing rib.
Described vortex eliminator comprises the air register of a level and the anti-swirl vane of the vertical and air register at the air register edge that is located at described level.
The gradient on the inclined-plane, bottom of described bucket body is 9 degree.
The width of the blade of described anti-leaf cover is 12 millimeters, has 32 outer shrouds that are arranged in anti-leaf cover uniformly.
The utility model can reduce the preceding water level of bucket, makes the utility model can directly apply to flat roof deck; And connection and fixed form are simple, reliable, and form good sealing effectiveness between the waterproofing course of top of building, and draining obtains effective the combination with waterproof.The utility model can be realized the secondary rectification of first rectification and vortex eliminator, realizes good gas-water separation state, eliminated the negative effect of whirlpool, has finished the required condition that storm-water system realizes high flow rate, big flow.

The specific embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2,3,4,5 below, the utility model be further detailed:
Embodiment 1: shown in accompanying drawing 1,2,3:
In the present embodiment, the utility model mainly is the antiseep that is applicable to metal roof, and it is made up of anti-leaf cover 1, vortex eliminator 2 and bucket body 4, and the top of described bucket body is provided with and connects flanging 44, connect flanging 44 and be level, directly will connect flanging 44 and weld mutually with metal roof and get final product.The gradient on 43 inclined-planes, bottom of described bucket body 4 is 9 degree.Anti-leaf cover 1 links into an integrated entity by standing screw 6 with bucket body 4.Be provided with reinforcing rib 11 at the top of described anti-leaf cover 1, and between described reinforcing rib 11, be provided with auxiliary inlet opening 12.The width of the blade 14 of described anti-leaf cover 1 is 12 millimeters, has 32 outer shrouds that are arranged in anti-leaf cover 1 uniformly.Described vortex eliminator 2 comprises the air register 21 of a level and the anti-swirl vane 22 of the vertical and air register 21 at air register 21 edges that are located at described level.5 is connecting pipe.
When the rainwater that roofing compiles flowed into roof drain, at first by anti-leaf cover 1, what be mingled with in the water can be by blade 14 barriers of anti-leaf cover 1 than bigger material, and foreign material can't enter in the storm-water system, avoid system pipeline blocked.The rainwater of flowing through can obtain blade 14 rectifications, and the rainwater fluidised form after the rectification will tend towards stability, flow velocity is even.Under the very big situation of rainfall, water level continues to rise before the bucket of roof drain, and when rainwater covered anti-leaf cover 1 top, the auxiliary water inlet 12 of anti-leaf cover 1 began water inlet, and the water inlet area increases, and the displacement of system also increases thereupon.The rainwater of preventing leaf cover 1 of flowing through imports roof drain bucket body 4.A ponding zone is formed in the bucket body inwall 42 of bucket body 4 and bucket body bottom 43, because the gradient on 43 inclined-planes, bottom of described bucket body 4 is 9 degree, this gradient aspect water (flow) direction, this gradient can prevent the bucket body bottom 43 local ponding of generation and improve the hydraulics of roof drain.Vortex eliminator 2 is close together with bucket body bottom 43.When rainwater is flowed through, anti-swirl vane 22 will be adjusted the flow shape of rainwater once more, and prevent the generation of eddy current, make the rainwater current situation of remittance system reach the imagination requirement.Then, rainwater imports tube connector 5 rapidly, and air register 21 intercepts rainwater and atmosphere, and air can't enter system, forms the rainwater one phase flow, and this process has been finished the essential condition that storm-water system realizes high flow rate, big flow.By vortex eliminator 2 and the sunk type bucket body of getting by oneself 4, the preceding water level of bucket of the present utility model is reduced greatly, roof drain satisfies the requirement that directly applies to flat roof deck.
Embodiment 2: as shown in accompanying drawing 4,5,6:
In the present embodiment, the utility model mainly is applicable to other building roofs except that metal roof.Flexible in order to guarantee the fixing mode in the utility model and roof, the utility model has increased a waterproof flange 3 between anti-leaf cover 1 and bucket body 4.Between waterproof flange 3 and the anti-leaf cover 1 can be overall structure.The waterproofing course and the secure bond of the present utility model that help the roof like this.Be provided with on the top of bucket body 4 and connect flanging 44, connect flanging 44 and be level, on described connection flanging 44, be provided with connecting hole 41.The gradient on 43 inclined-planes, bottom of described bucket body 4 is 9 degree.
When being when dividing body structure between waterproof flange 3 and the anti-leaf cover 1, anti-leaf cover 1 links into an integrated entity by standing screw 6 with bucket body 4; Utilize the connection flanging 44 of bucket body 4 to be provided with connecting hole 41, anchorage screw 7 sees through the anchoring circular hole 31 that is located at waterproof flange 3, and 4 threes are together fastening waterproof flange 3, waterproofing course, bucket body.Described waterproofing course is original waterproofing materials on the building.Other building roofs except that metal roof adopt above-mentioned fastening means, form good sealing effectiveness between roof drain and the waterproofing course, and draining obtains effective the combination with waterproof.In order to make the waterproofing course on the better fixed buildings of the utility model roof, the soffit 32 of described waterproof flange is a hackly surface.
Other parts and the embodiment 1 of present embodiment are identical.
