CN2419279Y - Self closed odorproof floor drainage - Google Patents

Abstract

The utility model discloses a self-closing anti-odor floor drain, which is provided with a partition 3 and a partition 5 in a floor drain body 2, a valve plate 4 is arranged between the two partitions, and the floor drain body 2 is separated by the two partitions Out of the water pipe 6 and the water trap 7, and form an "S" channel for water flow in the floor drain body 2. When water flows in, the water enters the floor drain body from the floor drain cover, and flushes open the valve along the "S" channel. The valve piece enters the water pipe, and when there is no water, the valve piece will return to its position naturally. The utility model is double-closed by the valve plate and the water in the water trap, avoids the gas overflow in the sewer pipe, and has a simple and novel structure and good reliability.

Description

self-closing deodorant floor drain

The utility model relates to a floor drain installed on a sewer pipe, in particular to a self-closing and deodorizing floor drain.

The floor drains disclosed in the prior art generally contain a floor drain cover, a floor drain body, and a water pipe, and the floor drain cover is provided with a water outlet. The negative pressure often destroys the water seal, causing the odor to overflow. When the water is not used for a long time, due to the evaporation of water, the water seal is often damaged, causing the odor to overflow. Therefore, the reliability of this kind of floor drain to seal the overflowing odor of the sewer pipe is relatively poor, and it is difficult to ensure that the indoor air is not polluted by using this floor drain.

The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art and provide an improved floor drain, which has good sealing effect and good reliability in use.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the utility model includes a floor drain cover and a floor drain body, and its structural feature is that two partitions are arranged in the floor drain body, and the two partitions separate the floor drain body from the water storage. Bends and water pipes, and valve plates are arranged between the two partitions.

Because the utility model is provided with two partitions in the floor drain body, the two partitions separate the floor drain body from the water trap and the water pipe, so that an "S"-shaped channel for water flow is formed in the floor drain body, and the two partitions The valve plate in between separates the water trap of the floor drain body from the water pipe. When the water flows into the floor drain body through the floor drain cover, the water flushes through the valve plate along the "S" channel and enters the water pipe. When there is no water, the valve sheet will automatically return to its position by gravity or elasticity. In this way, the gas in the sewer pipe cannot overflow because it is blocked by the valve sheet. At the same time, the water in the water trap also blocks the overflow of gas in the sewer pipe. Therefore, Through the double sealing of the valve plate and the water in the water trap, it is difficult for the gas in the sewer pipe to overflow.

Fig. 1 is the structural representation of the longitudinal section of the utility model embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail

As can be seen from Fig. 1, the utility model contains a floor drain body 2, a floor drain cover 1, a partition 3 and a partition 5 are arranged in the floor drain 2, and the partition 3 and the partition 5 separate the floor drain 2 from the water pipe 6 and the A water trap 7, a flexible valve plate 4 is arranged between the dividing plate 3 and the dividing plate 5, and one end of the valve plate 4 is installed on the dividing plate 3, and the valve plate 4 can rotate up and down along the o point. Water enters the floor drain body 2 from the floor drain cover 1, along the "S"-shaped channel formed by the partition plate 3 and the partition plate 5, flushes through the valve plate 4 and enters the water pipe 6, and enters the sewer pipe from the water outlet 8.
