Abstract

The utility model discloses a water seal floor drain which comprises a floor drain cover, a floor drain main body and a floor drain core, wherein the floor drain core comprises a floor drain core shell and an inner pipe; the inner pipe is arranged in the floor drain core shell; the floor drain core shell is formed by an eccentric inner pipe and the shell main body with unequal diameters, integrates the advantages of the existing water seal floor drain, overcomes the shortcomings of the existing water seal floor drain, takes account of the area of each section of a water current channel, promotes the speed and impulse of water current, and causes the drainage capacity and self-cleaning capacity of the water seal floor drain to be maximized.

Description

A kind of water-seal floor drain

Technical field

The utility model relates to a kind of floor drain, especially a kind of water-seal floor drain.

Background technology

Floor drain plays an important role in construction drainage as an important utensil getting rid of excess surface water.Floor drain should possess two kinds of basic functions: the one, and draining is smooth and easy, can get rid of excess surface water rapidly; The 2nd, good seal can effectively prevent in the foul smell inlet chamber in the sewer pipe; In addition, floor drain also should have good self-cleaning ability.Existing floor drain mainly is divided into hydrolock floor drain and Mechanical Sealed Type floor drain, compare with the Mechanical Sealed Type floor drain, advantages such as that the hydrolock floor drain has is simple in structure, no-movable part, long service life, reliability height, good sealing effect, but its drainage performance and self-cleaning ability often are affected because of structural defective.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, drainability strong, good sealing effect, be difficult for the water-seal floor drain that stops up and be easy to clear up.

Water-seal floor drain of the present utility model comprises drain cover, floor drain body and floor drain core, and the top of floor drain body is a drain cover, and floor drain core is installed in the floor drain body, and floor drain core is made up of floor drain core shell and interior pipe.There is the edge upper end of floor drain core shell for circular short tube, the main body of floor drain core shell is made up of the semi arch that two diameters do not wait, two semi arches intersect at a plane, and the lower end of floor drain core shell is a dome-type, in top, minor diameter semi arch one side of floor drain core shell delivery port are arranged.Interior pipe is installed in the floor drain core shell, and the upper end of interior pipe is a circular short tube, with the upper end tight fit inside of floor drain core shell; The main body of interior pipe is half pipe, by the upper end gradually transition form, the major diameter semi arch of the shape and size of semicircle pipe and floor drain core housing main body adapts; Interior pipe axially by the upper end or the location, lower end of floor drain core shell, interior pipe radially by the plane positioning of two semi arch intersections of floor drain core housing main body, make in the channel set of current by design and flow out, increased the scouring capability of current; The lower end of interior pipe is a delivery port.Water enters from the upper end of interior pipe, flow out the lower end, through floor drain core shell dome-type lower end and minor diameter semi arch main part, flow out from the delivery port of floor drain core shell, along the minor diameter semi arch main body outside of floor drain core shell and the space between the drainage pipe, enter in the main drainpipe road at last.Be the water seal of floor drain core between the delivery port of the delivery port of interior pipe and floor drain core shell, both differences in height are water seal height.For improving drainage performance and self-cleaning ability, the delivery port cross section of the flowing water section that the flowing water cross section of interior pipe, interior pipe lower end and floor drain core shell lower end form, the flowing water cross section of floor drain core shell minor diameter semi arch main body, floor drain core shell and the floor drain core shell minor diameter semi arch main body outside equate substantially with its area of free cross-section between the drainage pipe, that is to say current by floor drain core enter drainage pipe its section area of all passages of process equal substantially.

The beneficial effects of the utility model are that floor drain core adopts eccentric interior pipe and the design of not isometrical housing main body, concentrate the advantage of existing various water-seal floor drains and overcome its shortcoming, taken into account the area in each cross section of water stream channel, and internally pipe is effectively located, improved water velocity and current momentum, made the drainability of water-seal floor drain and self-cleaning ability reach maximization.

Description of drawings

Fig. 1 is the structural representation of water-seal floor drain, and arrow is depicted as water (flow) direction among the figure.

Fig. 2 is an A-A direction sectional view.

1. drain covers among the figure, 2. floor drain body, 3. floor drain core shell, pipe in 4.

The specific embodiment

With reference to the accompanying drawings, water-seal floor drain is made up of drain cover 1, floor drain body 2, floor drain core shell 3 and interior pipe 4.Drain cover 1 is above floor drain body 2, and floor drain core shell 3 is installed on the floor drain body 2, and interior pipe 4 is inserted in the floor drain core shell 3.The upper end of floor drain core shell 3 is the circular short tube that the edge is arranged, the main body of floor drain core shell 3 is made up of the semi arch that two diameters do not wait, two semi arches intersect at a plane, and the lower end of floor drain core shell 3 is a dome-type, in top, minor diameter semi arch one side of floor drain core shell 3 delivery port are arranged.Interior pipe 4 is installed in the floor drain core shell 3, and the upper end of interior pipe 4 is a circular short tube, with the upper end tight fit inside of floor drain core shell 3; In pipe 4 main body be half pipe, by the upper end gradually transition form, the major diameter semi arch main part of the shape and size of semicircle pipe and floor drain core shell 3 adapts; In pipe 4 axially by the location, lower end of floor drain core shell 3, interior pipe 4 radially by the plane positioning of two semi arch intersections of floor drain core shell 3 main bodys; The lower end of interior pipe 4 is a delivery port.The ponding on ground enters the floor drain body 2 from drain cover 1, upper end from interior pipe 4 enters again, the lower end flows out, through floor drain core shell 3 dome-type lower ends and minor diameter semi arch main part, flow out from the delivery port of floor drain core shell 3, along the minor diameter semi arch main body outside of floor drain core shell 3 and the space between the drainage pipe, enter in the main drainpipe road at last.After draining finishes, between the delivery port of the delivery port of interior pipe 4 and floor drain core shell 3, form water seal.
