Description
Technical field
The utility model relates to the drainage system of building, and more specifically a kind of anti-trapping floor drain that overflows belongs to the building water supply and drainage technical field.
Background technology
In the drainage system of at present domestic and international building, floor drain and drainage pipe are the most key parts, and functions anti-blocking and trapping two aspects are compared many considerations, and floor drain generally comprises cover and vertical fixing cylinder with cover.Aspect anti-blocking, general on cylinder on the cover of floor drain or adopt choke-preventing screen; And aspect trapping, consider at gutter generally that as adopting P type and S type trap pipe fitting, the water of the bending place by trap intercepts on the gas in the pipeline and moves.For straight gutter, no matter be P type or S type trap pipe fitting, all to take larger space, be unfavorable for the lifting of ceiling height between washroom and kitchen, simultaneously, there are the deficiencies such as waste of material, construction complexity.In addition, the function that does not possess the anti-spill-out aspect on existing floor drain and the gutter.
The utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined provides a kind of anti-trapping floor drain that overflows, it has the trapping function, can avoid gutter to adopt trap and the deficiencies such as large, the waste of material of causing taking up room, construction complexity, simultaneously, can prevent the spilling water of floor drain, the environment pollution of avoiding draining to overflow causing.
For achieving the above object, the utility model has adopted following technical scheme: a kind of anti-trapping floor drain that overflows, and it comprises cover and vertical fixing cylinder with cover, described cover is provided with choke-preventing screen, described choke-preventing screen is provided with several through holes, and it also comprises gas insulating cover and guide peg; The lower end of described cylinder has the bending greater than 90 degree, form trapping water district in the inboard of cylinder bottom, described gas insulating cover comprises the trapping cylinder and is arranged on the cover cap of trapping cylinder top end surface, the lower end of the trapping cylinder of described gas insulating cover falls into trapping water district, the lower surface of the cover cap of described gas insulating cover is provided with backstay, and described backstay end withstands on the end face of lower end bending of cylinder; Described guide peg is fixed on the center, upper surface of the cover cap of gas insulating cover, and the center of described choke-preventing screen is provided with pilot hole, and described guide peg passes pilot hole; The lower surface of described choke-preventing screen is provided with anti-overflow back-up ring, and the diameter of described anti-overflow back-up ring is less than the diameter of the cylinder of gas insulating cover, and on the described choke-preventing screen several through holes in the inboard of anti-overflow back-up ring.
For improving anti-overflow effect, the end of described anti-overflow back-up ring is provided with sealing ring, also can be provided with sealing mat on the cover cap of described gas insulating cover, and the shape of described sealing mat, size cooperate with anti-overflow back-up ring.
The bending of the lower end of described cylinder is 180 degree preferably.
Adopt said structure, because the lower end of the cylinder of floor drain has the bending greater than 90 degree, form trapping water district in the inboard of cylinder bottom, and the lower end of the trapping cylinder of gas insulating cover falls into trapping water district, make like this floor drain have good trapping effect.The lower surface of the cover cap of gas insulating cover is provided with backstay, and the backstay end withstands on the end face of lower end bending of cylinder, and the lower end bending that makes cylinder maintains a certain distance with the cover cap of gas insulating cover, has guaranteed the water flowing effect of floor drain.Described guide peg is fixed on the center, upper surface of the cover cap of gas insulating cover, the center of described choke-preventing screen is provided with pilot hole, described guide peg passes pilot hole, guaranteed that gas insulating cover can move up and down, when the pressure below the cover cap of gas insulating cover during greater than gas insulating cover gravity, gas insulating cover can abovely move, when below the cover cap of gas insulating cover do not have pressure the time, because gravity, gas insulating cover moves down.Because the lower surface of choke-preventing screen is provided with the setting of anti-overflow back-up ring, gas insulating cover can play Anti-spill after can abovely moving.
In sum, the anti-trapping floor drain that overflows of the present utility model, it has the trapping function, can avoid gutter to adopt trap and the deficiencies such as large, the waste of material of causing taking up room, construction complexity, simultaneously, can prevent the spilling water of floor drain, the environment pollution of avoiding draining to overflow causing.
