Odor-resistant and water-return-resistant floor drain and using method thereof

Abstract

The invention provides an odor-resistant and water-return-resistant floor drain and a using method. The floor drain comprises a floating ball assembly, an annular sealing ring and a water seal assembly, the floating ball assembly is located between a base of the water seal assembly and a guide cylinder of a cover plate and can move up and down within a certain range. Under normal conditions, when accumulated water in a cabin needs to be drained, water flow enters the floor drain from a water drainage hole of the cover plate and is further drained through a water outlet short pipe. When water flows back upwards to the floor drain, buoyancy generated by the upwelling water flows enables the floating ball to float to the position of the annular sealing ring and to be tightly attached to the annular sealing ring, so that the sealing effect is achieved, the upwelling water flows are prevented from entering the cabin through the floor drain, and the water-return-resistant function is achieved; meanwhile, a surrounding plate of the water seal assembly can establish a good water seal, so that odor is prevented from flowing upwards into the cabin, and the deodorization function is achieved; and in addition, all parts of the floor drain can be conveniently detached, and daily maintenance such as replacement and cleaning is facilitated.

Description

technical field [0001] The invention relates to the field of ship drainage appliances, in particular to an anti-odor and anti-backwater floor drain and a use method thereof. Background technique [0002] The deck drainage system of the ship is composed of accessories and pipelines, and is used to drain the accumulated water of each deck, each living compartment and working compartment. The deck drainage system mainly utilizes the downward self-flow of water, and discharges the accumulated water in various areas overboard through the floor drain and drainage pipes arranged on the deck. [0003] The deck leak is the first accessory to remove accumulated water. In different areas of the ship, different forms of floor drains need to be selected to meet the design requirements of various cabins. For example, due to the large water accumulation on the open deck, it is necessary to choose a form that can drain quickly. In the living cabin or the working cabin where people are stat...
