Double-liquid-seal floor drain with float ball blocking device

Abstract

The invention relates to the field of drainage systems and discloses a double-liquid-seal floor drain with a float ball blocking device. The double-liquid-seal floor drain comprises a floor drain shell, a floor drain cover is arranged at the upper end of the floor drain shell and detachably connected with the floor drain shell, an upper liquid seal device, a lower liquid seal float ball blocking device and a floor drain flange are arranged in the floor drain shell, and the upper liquid seal device and the lower liquid seal float ball blocking device are connected through the floor drain flange. By cooperation of the upper liquid seal device and the lower liquid seal float ball blocking device, when the upper liquid seal device is cleaned, the lower liquid seal float ball blocking device blocks off a lower port of a center pipe of the floor drain, a liquid seal state is still kept, odors, microorganisms, bacteria, insects, mosquitoes and flies in a drain pipe and air in a sewer pipe can be effectively prevented from entering a clean area, and accordingly the environment of the clean area is protected. In addition, the double-liquid-seal floor drain with the float ball blocking device has the advantages of structural simplicity and reasonability, excellent liquid seal performance, low manufacturing cost, convenience and quickness in operation, convenience in cleaning and sterilization and favorability in wide application and popularization.

Description

technical field [0001] The invention relates to the field of drainage systems, in particular to a double-liquid-sealed floor drain with a floating ball barrier. Background technique [0002] The national drug production quality management standard requires that pools and floor drains are prohibited in A / B grade clean areas for aseptic production. In other clean areas, pools or floor drains should have appropriate design, layout and maintenance, and be easy to clean and installed with The device with air blocking function to prevent backflow, and the connection method with the external drainage system should be able to prevent the intrusion of microorganisms. [0003] In addition, the atmospheric pressure of different operating rooms in some special industries will be different, and the atmospheric pressure of some operating rooms will be lower than the atmospheric pressure of the drainage system, so that the drainage system will damage the airtightness of the room or pollute...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a double-liquid seal floor drain with a floating ball barrier to overcome the failure of the floor drain liquid seal when the single-liquid seal floor drain in the prior art is disassembled and cleaned, causing odor, microorganisms, and bacteria in the drainage pipeline , insects, mosquitoes, and the air in the sewer pipeline enter the clean area, polluting the environment in the clean area, etc.
