Abstract

The utility model relates to a siphon rainwater fill with prevent swirl function. Including rainwater fill, rainwater fill chassis and PE pipe fitting, its characterized in that the rainwater fight with rainwater fill chassis between set up waterproof clamp plate, waterproof clamp plate is by having set gradually baffle limit, clamp plate inclined plane, clamp plate terminal surface and clamp plate hole outward in extremely, rainwater fill chassis and PE pipe fitting between be provided with O type circle, be provided with PE pipe fitting seal groove in the PE pipe fitting on the pore wall, O type circle set up in PE pipe fitting seal groove. The utility model discloses a fight to increase waterproof clamp plate and carry out configuration optimization the siphon rainwater, guarantee the splash and not beyond the scope of not spattering, dually prevent the swirl function, and push down waterproof material, be difficult for leaking, set up O type circle between rainwater fill chassis and the PE pipe fitting, guarantee chassis and the stability that the PE pipe fitting is sealed.

Description

A kind of siphon rainwater head with anti-whirlpool function

Technical field

The utility model relates to a kind of siphon rainwater head with anti-whirlpool function.

Background technology

Current architectural drainage system mainly contains siphon rainwater head and common roof drain two kinds.Although common roof drain is widely used, because drainage is poor, easily cause gutter ponding.Therefore, the roof drain application with siphon function is day by day extensive.Siphon rainwater head on existing market is not easily installed, and the problems such as interior cushion rubber is easily lost, damage, seem particularly evident when installation process, do not arrange secondary fairing, anti-whirlpool ability, easily bring air into and enter drainage system, even can not form siphon state.

Utility model content

For problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme with the siphon rainwater head of anti-whirlpool function.

Described a kind of siphon rainwater head with anti-whirlpool function, comprise roof drain, roof drain chassis and PE pipe fitting, it is characterized in that arranging anti-hydraulic pressure plate between described roof drain and roof drain chassis, anti-hydraulic pressure plate is disposed with baffle plate limit, pressing plate inclined-plane, pressing plate end face and plate hole from outside to inside; Be provided with O type circle between described roof drain chassis and PE pipe fitting, PE pipe fitting inner hole wall be provided with PE pipe fitting seal groove, described O type circle is arranged in PE pipe fitting seal groove.

Described a kind of siphon rainwater head with anti-whirlpool function, it is characterized in that described roof drain, anti-hydraulic pressure plate and roof drain chassis are fixed together after setting gradually from top to bottom, roof drain chassis and PE pipe fitting are fixed together.

Described a kind of siphon rainwater head with anti-whirlpool function, is characterized in that described O type circle is arranged in PE pipe fitting seal groove and the upper surface of O type circle and touches with roof drain chassis and coordinate.

Described a kind of siphon rainwater head with anti-whirlpool function, is characterized in that the diameter of described plate hole is greater than the diameter of bore on roof drain chassis.

Described a kind of siphon rainwater head with anti-whirlpool function, it is characterized in that described PE pipe fitting inner hole wall is also provided with PE pipe fitting seal groove oblique angle, PE pipe fitting seal groove transits to PE pipe fitting endoporus by PE pipe fitting seal groove oblique angle.

The utility model, by increasing anti-hydraulic pressure plate to siphon rainwater head and carrying out structure optimization, ensures that spray is not outer and spatters, dual anti-whirlpool function, and push down waterproofing materials, antileaking; O type circle is set between roof drain chassis and PE pipe fitting, ensures the stability that chassis and PE pipe fitting seal.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described in further detail:

A kind of siphon rainwater head with anti-whirlpool function, comprise roof drain 1, roof drain chassis 2 and PE pipe fitting 3, anti-hydraulic pressure plate 4 is set between roof drain 1 and roof drain chassis 2, anti-hydraulic pressure plate 4 is disposed with baffle plate limit 6 from outside to inside, pressing plate inclined-plane 7, pressing plate end face 8 and plate hole 9, the diameter of plate hole 9 is greater than the diameter of bore on roof drain chassis, by the current after siphon rainwater head, fall the baffle plate limit 6 of anti-hydraulic pressure plate again, can effectively prevent from spattering outside spray, by pressing plate inclined-plane 7, play buffering current, anti-whirlpool function, by pressing plate end face 8, effectively can play and push down roof waterproof layer, make roofing antileaking, seamless link can be carried out with roof waterproof layer and roof drain chassis by the screw hole on anti-hydraulic pressure plate to fix, O type circle 5 is provided with between roof drain chassis 2 and PE pipe fitting 3, PE pipe fitting inner hole wall is provided with PE pipe fitting seal groove 10, O type circle is arranged in PE pipe fitting seal groove and the upper surface of O type circle and touches with roof drain chassis and coordinate, PE pipe fitting inner hole wall is also provided with PE pipe fitting seal groove oblique angle 11, PE pipe fitting seal groove and transits to PE pipe fitting endoporus by PE pipe fitting seal groove oblique angle.Be fixed together after roof drain, anti-hydraulic pressure plate and roof drain chassis set gradually from top to bottom, roof drain chassis and PE pipe fitting are fixed together.

Concrete, 0 type circle external diameter is fixed in PE pipe fitting seal groove, makes it not depart from, and exposes surplus by the upper surface of 0 type circle, effectively can seal roof drain chassis and PE pipe fitting, make connecting portion water-tight; The endoporus of PE pipe fitting plays a role in the drainage, and PE pipe fitting seal groove oblique angle 11 plays that not withstand roof drain chassis end-acted, and PE pipe fitting seal groove 10 is enclosed and roof drain chassis sealing function by 0 type.
