A clean air-conditioned room automatic replenishment floor drain

Abstract

The invention relates to a floor drain for automatically replenishing water in a clean air-conditioning room, comprising: a drain pipe, a U-shaped water trap, a water outlet pipe, a floor drain water tank, a floating ball, a floor drain support grid, a floating ball valve, and a running water pipe. The floor drain tank is covered with a floor drain support grid, the tap water pipe is connected to the lower part of the floor drain tank through a ball float valve, the lower part of the floor drain tank is connected to a water outlet pipe, and the water outlet pipe, U-shaped water trap and drain pipe are connected in sequence. The support grid of the floor drain is made of flat steel vertically arranged in a grid shape, and the material of the flat steel is stainless steel. The floor drain water tank is made of 4mm to 8mm steel plate, and the surface is treated with antirust. The invention can automatically replenish water to the water tank, so that there is always water in the U-shaped bend, and can always isolate the inside and outside of the clean room, preventing outdoor air or reptiles from climbing into the clean air-conditioning room from the outside, affecting the air quality of the clean air-conditioning room. And then affect the product quality.

Description

technical field [0001] The invention relates to a floor drain, in particular to a floor drain for automatically replenishing water in a clean air-conditioned room. Background technique [0002] Nowadays, clean air conditioners are generally used in electronic and pharmaceutical factories. Due to the needs of production, clean air conditioners sometimes discharge a large amount of waste water suddenly, and sometimes there is no drainage for a long time. These waste water are often concentrated in the discharge, which requires a relatively large Drain pipes and floor drains. Ordinary floor drains are isolated by U-shaped bends. When there is no water discharged from the clean air-conditioned room for a long time, the water in the U-shaped bends will evaporate to dryness. At this time, there is no water in the U-shaped bends, and the water seal cannot be formed, and the inside and outside air cannot be isolated. and reptiles enter the system, affecting the air quality of the c...
