Description

Novel sewer line with major-minor check valve

Technical Field

The invention belongs to the technical field of sewer pipes, and particularly relates to a novel sewer pipe with a main check valve and an auxiliary check valve.

Background

The drainage device in the prior art, such as a drainage device, a floor drain and a sewer pipe, is a drainage part commonly used in a kitchen and a toilet lamp place, and generally has a function of deodorization and insect prevention besides a drainage function. At present, the existing drainage devices mainly adopt a water seal mode to realize the functions of deodorization and insect prevention. However, the drainage device adopting the water seal to realize the deodorization function has the following disadvantages:

1. when the drainage device is not used for a period of time, water for realizing water sealing can be dried, so that odor in a sewer overflows; if the water used for realizing water sealing is dirty water, the water is easy to smell and blacken after a period of time, grows bacteria and is not beneficial to environmental sanitation.

2. Most of the sewer pipes only realize deodorization at the sewer opening of the water pool, but ignore odor possibly emitted by the ground pipeline due to the fact that sealing measures are not in place.

The existing sewer pipe is a pipeline used for connecting a sewer pipe and a ground pipeline, in order to avoid backflow of sewage and rising of odor to a room, people generally select a deodorization device connected to the sewer pipe to prevent odor and backflow of sewage, and the current market is commonly provided with a floating ball deodorization device or a check valve device. At present, sewer pipelines with backflow prevention functions on the market are mostly provided with backflow prevention devices which can be designed on a core pipe, if a main pipeline is blocked, sewage in a relatively high main pipeline can flow back into a relatively lower auxiliary pipe or side pipe, and therefore water backflow pollution is caused.
