Description
Technical field:
The plug-in type reducing counterflow-preventing attachment means that the utility model is related to, belong to roof water-proof field.
Background technology:
Sealing is a kind of mode that on the market a kind of common prevention is leaked.When liquid moved to by a pipeline it is another
During individual pipeline, the intersection of two pipelines can be passed through.And join between two passages and inherently have gap, and liquid will be from seam
Ooze out in the middle of gap.The reason for causing leakage mainly has two aspects:One is have gap in sealing;Two be sealing position both sides exist compared with
Big pressure differential.Eliminating or reduce arbitrary factor can prevent or reduce leakage.Therefore the method for sealing generally has:1. knot is sealed
The gap in conjunction face;2. leakage path is cut off;3. the resistance of leakage path is increased;4. work done element is set, leaking medium is caused
Pressure, with counteracting or the pressure differential of balance leakage passage.
Domestic flat roof deck draining is always a bit that designers pay close attention to the most.Roof plan is the heavy calamity for accepting rainwater
Area, water guide draining can effectively prevent the convergence of rainwater, so as to the leak of water guide roof.The drain gully of roofing is exactly for this side
Face and set up.Drain gully cannot be fabricated to integrated with downpipe, then the junction for being accomplished by sealing two tube walls reaches and leads
The effect of water.
At home, roofing drain port docks adopted mode with downpipe for two kinds:1. the two pipe laps of splice are lengthened, 2.
Encapsulation process is done using O-ring.First kind of way, plus long overlap can increase extra cost, and for circumscribed place
(Where side comb and height limitation)And do not apply to.The second way is just more relatively reasonable, O-ring seal is enclosed within overboard
On the upper pipeline of mouth, in pre-buried lower pipeline is inserted;It is O-shaped close when the lower pipeline of upper pipeline insertion but it there is also drawback
Seal can be stretched by lower pipe friction, cause sealing effectiveness not good.When the reason for installing or when the later stage finds infiltration, lift overboard
Mouth upper conduit sections point O-ring seal can be lost in lower pipeline.
The content of the invention:
The purpose of this utility model is to provide a kind of easier, the firm, anti-overflow of installation, non-maintaining plug-in type to become
Footpath counterflow-preventing attachment means.
For above technical problem, the plug-in type reducing counterflow-preventing attachment means that the utility model is related to, including sealing ring,
Insertion tube and built-in pipe, the outside diameter d of the insertion tube is less than the outer diameter D of built-in pipe, and the sealing ring has Relative vertical direction
Inclined inner and outer wall, the outer wall has the gill ring of multilayer and sealing ring upper surface relative tilt, and the gill ring is uniform
It is distributed on the outer wall of sealing ring, the inwall is provided with cannelure corresponding with sealing ring, the inwall downside is additionally provided with and prevents
The counterflow-preventing barb of liquid countercurrent.
Preferably, the wall in order to reduce waste of material, the insertion tube and built-in pipe while waterproof effect is improved
Thick RT is 1.6mm-8.0mm.
Preferably, the outside diameter d of the insertion tube is 40mm-145mm, the built-in pipe outer diameter D is 50mm-160mm, in advance
The difference of the outside diameter d of pipe laying outer diameter D and insertion tube is 10mm-35mm.
Preferably, the connection effect in order to improve two sections of connecting tubes, the gill ring is with sealing ring upper surface inclination angle B
28°-45°。
Preferably, in order to while sealing effectiveness is increased, make the lighter institute of installation of attachment means, the gill ring
Quantity is 5.
Preferably, in order that inwall realizes locking effect, the included angle A of the inwall vertical direction when tubing is connected
Less than in the angle C in outer wall vertical direction.
Preferably, for the ease of two sections of tubing by plug-in type reducing counterflow-preventing attachment means connect, the outer wall with
The angle C of sealing ring upper surface is 2 ° -4 °.
It is of the present utility model to be beneficial in that compared with technology before:Easier, firm, anti-overflow is installed, exempts from dimension
Shield, can effective locking connecting tube, prevent sealing ring from dropping, the grafting of achievable reducing is suitable for the tubing of Multiple Type, sealing ring
Using multilayer gill ring, be suitable for the wall thickness produced by unlike material under identical outer tube diameter, install while increasing sealing effectiveness
It is lighter.
Description of the drawings:
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the scheme of installation of plug-in type reducing counterflow-preventing attachment means;
Fig. 2 is the structural representation of sealing ring;
In figure:1st, sealing ring;2nd, insertion tube;3rd, built-in pipe;4th, inwall;5th, outer wall;6th, gill ring;7th, cannelure;8th, it is anti-reverse
