In drainage pipe, there is negative pressure, described anti-dry ball float (3) seals the tubaeform mouth of pipe of water seal cylinder (202) of described water-sealed component (2), prevent that the water in water-sealed component (2) is sucked loss, guarantee that water seal has enough degree of depth, to stop drainage pipe harmful exhaust to enter room, be detrimental to health.
Each part dimension of described floor drain is according to the corresponding change of caliber size of the drainage interface of described floor drain body (1), but planform is constant.
Described anti-dry floor drain is except anti-dry ball float (3), described anti-dry other component of floor drain, except adopting the stamping forming processing method of metal sheet roof covering shown in the utility model structural representation, also can adopt other metal material casting processing and forming technology, or injection molding processes.Its planform is constant, and physical dimension can be adjusted according to processing technology difference.
Floor drain provided by the utility model, with respect to prior art, at least has following benefit:
The mushroom-shaped centrum shape of anti-dry ball float can form good contact with the mouth of pipe of the tubaeform transition arc of water seal cylinder, to play the effect of good sealing water seal bobbin mouth.
The anti-dry ball float taper small end of design bottom surface is concordant with water seal bowl upper edge (water seal liquid level).After can making the tubaeform disk ponding of draining initial stage water seal cylinder will prevent that dry ball float floats, the water level rising in water seal cylinder still can continue the anti-dry ball float of support because of buoyancy, makes draining flow to the state of being held open, and displacement is larger, ball float ascensional range is higher.Played the effect that automatically regulates draining runner gap according to displacement.After draining stops, anti-dry ball float automatic fall-back, in the tubaeform mouth of pipe of water seal cylinder, seals the mouth of pipe.When negative pressure appears in sewerage system, due to the effect of suction force, the anti-dry ball float conical surface is tightr with contacting of the tubaeform mouth of pipe of water seal cylinder.Both guaranteed the normal drain function of floor drain, can prevent again that water seal evaporation from drying up and negative pressure suction causes water seal to run off.
The mushroom-shaped that anti-dry ball float is round and smooth and the design of the tubaeform mouth of pipe arc transition of water seal cylinder, be not easy by sagging fiber solid content and hair in sewage, guaranteed the sealing effectiveness of anti-dry ball float.
Anti-dry ball float adopts lightweight elastoplast or rubber hollow design, not only can lower draining noise, also can make its sealing effectiveness better because of its elastic deformation characteristic.
The anti-dry floor drain of side-type has adopted the combination of water-sealed component and side-type floor drain body, greatly reduces the height dimension of floor drain.As the anti-dry floor drain of the side-type that is mainly used in co-layer draining installation, this size has often determined whether bathroom floor layer adopts the building structure of falling plate.Not only building costs is high to fall plated construction, and falls and in plate packing course, often after washroom comes into operation, form ponding, produces stink.The anti-dry floor drain of side-type of present design, for the washroom of some house types, just can be installed without falling plated construction.Not only reduce building costs, saved architectural space, also avoided occurring in using the worry of packing course internal water accumulation in the future.
Compare with float-ball type water-seal floor drain in the past, anti-dry floor drain of preventing back overflow planform of the present utility model and size more meet the requirement of the relevant Code for design of building water supply and sewerage of country.It has not only guaranteed minimum water seal depth and the water flowing sectional area of 50mm from structure, and adopts the supplementary structure of anti-dry ball float to carry out effective protection to water seal.
And, the structure of the floor drain body that the utility model provides, water-sealed component, double-edged fine-toothed comb seat and double-edged fine-toothed comb is in order to adapt to the design of stainless sheet steel punch forming processing mode, according to user's needs, theory and structure shape according to this programme, adopt other carft of constructions such as metal casting moulding or injection molding, still can realize the purpose of this utility model.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
