Abstract
The utility model discloses a backward flowing prevention floor drain device, which comprises a cylindrical sewer pipe, and is characterized in that a circular disc-shaped sealing disc for sealing the sewer pipe is arranged in an inner cavity of the sewer pipe, a circle center part of the sealing disc is provided with a penetrating water discharge hole, the lower part of the water discharge hole is provided with a floating ball cover for covering the water discharge hole, and a floating ball is movably arranged in the floating ball cover. The backward flowing prevention floor drain device utilizes a simple floating ball sealing and plugging device for manufacturing a one-way valve, so the overflowing and backward flowing phenomena of a floor drain are effectively avoided. The backward flowing prevention floor drain device has the advantages that the structure is simple, the effect is good, the cost is low, and the like.
Description
Technical field
The utility model relates to a kind of reverse-filling floor drain apparatus, in particular for the reverse-filling floor drain apparatus in pharmaceutical factory.
Background technology
Pharmaceutical factory is very high for the requirement of health, so gutter can install common floor drain usually, then a bend pipe also can be set carry out water seal, the supply mains of then running in.Floor drain directly connects the gutter of purifier usually.If the instantaneous displacement of a certain purifier is excessive, then easily causes adjacent floor drain to produce and overflow, pour in down a chimney in the coupled purifier of meeting, thereby produce contamination accident.How to prevent the generation of this accident, when guaranteeing long-term normal the use, saving as far as possible cost is present problem demanding prompt solution.
Summary of the invention
The utility model provides a kind of solution of the above problems, and a kind of simple in structure, effective, reverse-filling floor drain apparatus that cost is low is provided.
The technical solution of the utility model provides a kind of reverse-filling floor drain apparatus, it comprises the cylindrical shape sewer pipe, it is characterized in that: be provided with the disc closed disk with described sewer pipe sealing in the described sewer pipe inner chamber, described closed disk circle centre position is provided with the drain hole that runs through, described drain hole bottom is provided with the ball float cover that described drain hole is covered, and is movably set with ball float in the described ball float cover.
Preferably, described ball float cover comprises some rod cover bars perpendicular to described closed disk, and the free end of all described cover bars links together.
Preferably, described ball float covers one deck rubber layer outward, is used for strengthening the sealing between ball float and the drain hole, certainly is not limited to rubber, and other common soft materials that are used for sealing can.
Reverse-filling floor drain apparatus of the present utility model utilizes a simple ball float plugging device to produce an one way valve, thus the limited phenomenon of having avoided floor drain to overflow, pour in down a chimney.Reverse-filling floor drain apparatus of the present utility model has simple in structure, effective, low cost and other advantages.
Description of drawings
Fig. 1 is the structural representation of reverse-filling floor drain apparatus of the present utility model;
Fig. 2 is the top view of closed disk among Fig. 1.
The specific embodiment
The below is described in further detail the specific embodiment of the present utility model.
As depicted in figs. 1 and 2, a kind of reverse-filling floor drain apparatus of the present utility model comprises cylindrical shape sewer pipe 10, and sewer pipe 10 is stainless steel normally.Be provided with the disc closed disk 12 with sewer pipe 10 sealing in sewer pipe 10 inner chambers, closed disk 12 is stainless steel normally also, is fixed in the sewer pipe 10 by weld horizontal.Closed disk 12 circle centre positions are provided with the drain hole 14 of the circle that runs through, and drain hole 14 bottoms are provided with the ball float cover 16 that drain hole 14 is covered, and are provided with ball float 18 in the ball float cover 16.Ball float cover 16 is the cover bars 20 that are vertically welded in the stainless steel steel wire on the closed disk 12 by the 3-4 root, and the free end of all cover bars 20 links together.Certainly, the grid-shaped that ball float cover 16 also can be comprised of the stainless steel steel wire can cover ball float 18.Ball float 18 can be a hollow steel ball, and its outer one deck rubber layer (not shown) that covers is used for strengthening the sealing between ball float 18 and the drain hole 14, certainly is not limited to rubber, and other common soft materials that are used for sealing can.
After a kind of reverse-filling floor drain apparatus of the present utility model installed, during normal draining, ball float 18 was positioned at ball float cover 16 bottoms, and sewage is discharged around ball float 18.In case pour in down a chimney, the water level of ball float 18 belows rises, and ball float 18 rises under buoyancy, thereby drain hole 14 is blocked; Buoyancy is larger, and ball float 18 shutoff must be tighter.So just can realize unidirectional shutoff, thereby effectively avoid the contamination accident of pouring in down a chimney.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
