Abstract

The utility model discloses a flap floor drain for a sewer, comprising a short cylinder-shaped case sheathed with the sewer. A water outlet is arranged in the case. A flap sealing door with a lever structure is arranged under the water outlet. One side of a supporting point is a flap plate, and the other side is provided with a balance weight object. The gravitational moment of the balance weight object is greater than the gravitational moment of the flap plate. Usually, the flap plate is tightly clung to the lower part of the water outlet because the action of the gravitational moment of the balance weight object. When water is drained, the flushing water overcomes the gravitational moment of the balance weight object and rotates the lever structure. Thus, the flap plate leaves the water outlet for draining the water. After the water is completely drained, the flap plate is tightly clung to the lower part of the water outlet again because the action of the gravitational moment of the balance weight object. Therefore, odor in the sewer can not enter a room.

Description

Flap floor drain for sewer

The utility model relates to sanitary installation, particularly indoor sewer floor drain.

At present, indoor sewer floor drain major part is a hydrolock, and it is to form by the garden hat gland of several projections with at the outer peripheral annular groove of sewer water inlet with the edge.It covers sewer mouth and the water in annular groove by garden hat gland and forms a circle water seal, make water can by and gas can not be by in the foul smell inlet chamber that intercepts sewer.

This floor drain can not be in line because of water, and sewage overflows into sewer after entering annular groove.So the solids in the sewage accumulates in annular groove easily and stops up sewer.In addition, it is that the part of two separation is formed, be easy to scatter and disappear and the sewer mouth is opened wide, and deodorization not only, mouse, cockroach, damp worm etc. are also thus in the inlet chamber.

The purpose of this utility model provide a kind of can in line sewage, sealing mechanical type sewer floor drain reliable, easy to install.

The utility model is realized with the following method.

Floor drain has short cylindrical Shell, outfall is arranged in the housing, the turnover plate type hermatic door is arranged under the outfall, the turnover plate type hermatic door is a lever construction, it is mass that its fulcrum one end is used turnover panel, the other end for sealing, and fulcrum is an axle, be located at the next door below the outfall, the gravitational moment of mass is greater than the gravitational moment of turnover panel.Usually turnover panel is close under the outfall because of the gravitational moment effect of mass.During use, short cylindrical Shell is installed in the sewer water inlet, when draining, sewage flows into outfall, and the gravitational moment of water can overcome the gravitational moment of mass on turnover panel, makes the lever rotation and opens outfall water is discharged.After water drained, turnover panel can be close on the outfall because of the gravitational moment effect of mass again, made the outfall sealing.

The utility model has the advantages that:

1, sewage can directly be discharged, and draining is unobstructed, and solids can not accumulate in outfall in the sewage.

2, sealing is reliable, particularly arrange at every turn and can deposit low amounts of water formation water seal on the water end blocking, make the sewer stink can not inlet chamber in.

3, mouse, cockroach, damp worm can not pass through in the sewer mouth inlet chamber in the sewer.

4, simple in structure, easy for installation.

Fig. 1 is the generalized section of turnover plate type sewer floor drain.

Among Fig. 1, in the short cylindrical Shell 1 outfall 2 is arranged, outfall 2 is horn mouth towards top, flow in order to sewage, towards the lower part is flat mouthful, can be adjacent to turnover panel 32, and the fulcrum 31 of hermatic door 3 is on the next door of outfall 2 bottoms, one side is a turnover panel 32, opposite side is a mass 33, enters in the sewer for preventing solids bigger in the sewage, and grate 4 is arranged on the horn mouth of outfall 2, during installation, floor drain is contained on the inlet of sewer.Sewage keeps off solids bigger in the sewage on grate 4 by grate 4 during draining, and effluent stream is washed turnover panel 32 open to outfall 2 and entered sewer, after the water emptying, turnover panel 32 is closed automatically, can leave low amounts of water at turnover panel 32 and outfall 2 edges, make sealing tight, stink can not pass through.

Claims

1, a kind of turnover plate type sewer floor drain is characterized in that:

A. it has short cylindrical Shell,

B. in the short cylindrical Shell outfall is arranged,

C., the turnover plate type hermatic door is arranged under the outfall.

2, by the described floor drain of claim 1, it is characterized in that the turnover plate type hermatic door that described turnover plate type hermatic door is a lever construction, a side of its fulcrum is a turnover panel, and opposite side is a mass, and the gravitational moment of mass is greater than the gravitational moment of turnover panel.
