Turnover board-type large-flow straight-drainage stinking-proof floor drain arranged outside pipeline

Abstract

The invention provides a turnover board-type large-flow straight-drainage stinking-proof floor drain arranged outside a pipeline. The floor drain comprises a floor drain housing, a fine-toothed comb,a drain core drum body, turnover boards and a water drainage hole. An open-close device for the floor drain is arranged outside a water drainage pipe. The water drainage pipe is wrapped in the interior of the floor drain and connected to the water drainage hole. The water drainage hole is equipped with a water blocking ring. The open-close device for the floor drain is in the structure of a turnover board. One side of each turnover board is equipped with a rotary shaft. Each rotary shaft is installed into a shaft hole in the drain core drum body equipped with leakage holes. When water is not drained, the turnover boards closely contact edges of the leakage holes in the drain core drum body under effect of a balancing mechanism in order to prevent smell in the sealed and closed state. Whenwater is drained, the turnover boards are opened under water effect. Therefore, water flows enter the water drainage pipe. After water drainage, the turnover boards are closed again after effect of the balancing mechanism. The pipe diameter of the water drainage pipe does not increase. Due to large flow quantity, obstruction and overflow are not likely to occur. The turnover board-type large-flowstraight-drainage stinking-proof floor drain arranged outside the pipeline can be applied to a shallow sewer line.

Description

technical field

[0001] The invention relates to a drainage floor drain, in particular to a large-flow straight-drain anti-odor floor drain with external flaps of pipes. It has the characteristics of not wasting the water area of ​​the drainage pipe. Background technique

[0002] The most common anti-odor and anti-overflow floor drains in the market are water-sealed anti-odor floor drains, T-shaped floor drains, silicone-type sealed floor drains, and lever flap-type floor drains. Different degrees of waste affect the speed of launching. For this reason, it is necessary to improve and perfect the floor drain of the above-mentioned structure. Contents of the invention

[0003] In view of the above situation, the present invention provides a large-flow deodorant floor drain with a flap outside the pipe, so that water flows into the floor drain through the flap and then directly discharged into the drainage pipe, making full use of the drainage area of ​​the drainage pipe. ...
