Description
Technical field
The utility model is related to sanitation technical field, specially a kind of household sewer anti-return dress for kitchen use
It sets.
Background technology
Sewer is a kind of urban public utilities, refers to the pipeline of building draining-off sewage and rainwater, also refer to city, plant area or
The underpass of village draining-off sewage and rainwater, currently, skyscraper is more and more, since pipeline is meticulous, crook design does not conform to
Reason, sundries siltation, are especially influenced in dead season due to easily being lumpd by greasy dirt, and sewer pipe easily is turned to deposit at sharp turn and be blocked up in bottom
Plug causes blowdown unsmooth, thereby tends to sewage can be caused assemble to rise in pipeline and be back to main sewer pipe to connection due to blocking
In logical bottom building, especially sometimes in family it is long-term nobody, large amount of sewage can be caused to enter, its resident family is enabled to suffer untold misery.For
How this prevents drain of kitchen anti-return from having become a problem urgently to be resolved hurrily：
