Task of the present utility model provides two kinds of floor drains, and first kind can close gas in the pipeline all the time, and it can not be released; Second kind can close all the time that gas can not release it in the pipeline, can prevent that again liquid flows backwards out by floor drain in the pipeline.

For achieving the above object, the scheme of two kinds of floor drains of the present utility model is: these two kinds of floor drains are formed by the bottom and the moving valve of the top cover of floor drain, floor drain wall, floor drain.Top cover, floor drain wall and bottom are formed the floor drain body.The floor drain body includes moving valve, and the liquid that moving valve can be entered floor drain floats.Have suitable for readingly on the top cover, have end opening on the bottom.

The end opening of first kind of floor drain can be closed by moving valve, and moving valve is positioned at the position that can close end opening all the time.When not having liquid to flow through this first kind of floor drain, moving valve seals the mouth of staying and makes that gas can not release in the pipeline under action of gravity; When liquid was flowed through this first kind of floor drain, moving valve was floated by liquid, and liquid can pass through the end opening flow ipe.In this liquid flow process, liquid or liquid and moving valve seal end opening together all the time, and gas can not be released.After liquid flowed out, moving valve sealed end opening again under action of gravity.

Suitable for reading or the end opening of second kind of floor drain all can be closed by moving valve, moving valve is positioned at the position that can close suitable for reading or end opening all the time, when not having liquid to flow through this second kind of floor drain, moving valve seals the mouth of staying under action of gravity, makes that gas can not release in the pipeline; When liquid was flowed through this second kind of floor drain, moving valve was floated by liquid, and liquid is by the end opening flow ipe, and in this liquid flow process, liquid or liquid and moving valve seal end opening together all the time, made that gas can not release in the pipeline; When liquid blowed back into this second kind of floor drain from pipeline, moving valve was at first floated, when by floating when suitable for reading, just with sealing suitable for reading, liquid can not be flow backwards away.After liquid outflow floor drain entered pipeline in the floor drain, under action of gravity, moving valve sealed end opening again.

The utility model has the advantages that: (1) first kind of floor drain can close gas in the pipeline all the time.(2) second kinds of floor drains can close all the time that gas can prevent that again liquid flows backwards out by floor drain in the pipeline in the pipeline.(3) two kinds of drain structures are all simple.
