Sewer decomposer

Abstract

The sewer decomposer includes one main structure comprising water inlet end cap, float ball bin and water outlet end cap connected successively, float ball set inside the float ball bin, and upper sealing ring and lower sealing ring set separately on the water inlet end cap and the water outlet end cap. The close contact between the upper sealing ring and the lower sealing ring with float ball avoid the upward flow of sewage and the leakage of the sewer smell. The upper sealing ring has concave spherical surface of curvature radius equal to or smaller than the radius of the float ball, while the lower sealing ring has concave spherical surface of curvature radius equal to or greater than the radius of the float ball, so that one layer of water film in certain tension is formed between the float ball and the lower sealing ring for avoiding the leakage of bad sewer smell. The present invention may be used to replace traditional drain trap and floor drain.

Description

technical field [0001] The invention relates to a sewer pipeline device, in particular to a sewer decomposer capable of effectively sealing odor and blocking sewage. Background technique [0002] At present, it is mostly said that urban residents are troubled by the peculiar smell and the breeding of mosquitoes and flies in the sewer at home. Therefore, preventing various harmful viruses and bacteria from passing through the sewer has attracted great attention of experts. The anti-blocking and deodorization of traditional sewers mostly use elbow devices, and the water in the elbows is used to seal the odor. Though this structure has certain effect, can cause dirt to gather at bend pipe place for a long time, light one still can make foul smell distribute, and heavy one causes pipeline blockage, and dirt turns up, and causes serious loss and misery to the family. In addition, the structure takes up a lot of space and is no longer suitable for the structural requirements of m...

Problems solved by technology

[0004] Although the above working principle can realize the effect of avoiding the upturning of sewage and sealing the odor, there are still some problems, such as because the floating ball is relatively light, it is obvious that only relying on the weight of the floating ball cannot completely seal the sewer odor; when the sewage is turned up , only relying on the line contact between the floating ball and the taper surface of the upper water pipe cannot achieve complete sealing, and sewage will still be precipitated

[0005] Therefore, in actual use, the above-mentioned technical solution only solves the problem of sewage upturning to a certain extent, and does not really solve the problem of sewer odor gas overflow
