KR200369779Y1 - A cut-off of flowing backward of stench and insect using the trap from a sewer pipe - Google Patents

Abstract

Sewer pipelines are subject to gravity, unlike water supply pipelines. Therefore, the water in the tube flows with free water surface, and it is extremely rare for the tube to be full. In addition, when water does not flow in the pipeline, the pipe becomes empty, and in the case of a combined pipeline, odors and worms easily flow from the sewage main pipe through household sewage. The present invention is to provide a trap for odor and insect blocking at the outlet end of the home sewage, and always stores water in the trap. This device allows the water in the tube to flow freely at all times, inhibits the communication of air or gas, and also prevents the ingress of insects.

Description

A device for blocking odor reflux and preventing pest inflow into a sewage pipe using a trap {A cut-off of flowing backward of stench and insect using the trap from a sewer pipe}

Sewage pipes are gravity-controlled, unlike water supply lines, which are subject to water pressure. Usually, the water in the pipe flows while maintaining the free surface, so it is rarely flowed into the pipe. In addition, when water does not flow, the inside of the pipe becomes empty, and in the combined pipeline, odors and worms flow from the sewage main pipe through household sewage. Drain traps are installed in the sinks and sinks of each household to prevent odor backflow from existing household sewage. However, backflow of odors and pests from branch sewers to house sewers is free. In particular, in conventional houses without drain traps, they are exposed from odor through household sewage, causing serious sanitation problems. If the conventional sewage trap installed in the sink, wash basin, etc. is a secondary device for preventing odor backflow in domestic sewage, the present invention primarily suppresses the odor and worm backflow from the branch sewage to the home sewage collection. ㆍ The purpose is to block.

The present invention is a device for preventing odor backflow in a sewage main pipe in the above-mentioned combined sewage pipe line. That is, it is installed at the confluence point of the outflow end of the domestic sewage pipe line and the branch line sewer pipe (sewer main pipe), and water is freely communicated by always storing water in a trap, but it is a device which suppresses the inflow of air, gas, and insects. In this way, the present invention can achieve a technical problem that can primarily block the backflow of odor.

The present invention is a blocking device for preventing backflow of odor in the sewage main pipe in the above-mentioned combined sewage pipe. Figure 1 shows the entire configuration of the device of the present invention, Figure 2 shows a state in which the blocking device is installed and operated in the drain pipe.

The construction of the present invention is composed of a trap to block odor, a tightening band for fixing the tube to the drain pipe. The components are described in detail as follows.

Tightening band (1) is a device for fixing the odor blocking device (trap) to the combined sewage pipe of rainwater and sewage, the material is made of a metal band or rubber band.

The trap 2 is made of a synthetic resin molded material, and may be simply connected using an elbow from the middle joint of the trap.

The joints 3 are placed so as to be separable in the middle of the trap to facilitate cleaning and maintenance. In addition, if necessary, a cap is installed at the outlet of the trap to block odor reflux and the influx of insects caused by the evaporation of water accumulated in the trap.

The odor blocking device of the present invention not only can clean the inside of the trap by drainage of the drain pipe and prevent congestion of dirt, but also has a simple structure and easy maintenance. In addition, water is freely communicated, but there is an advantage that can completely block the communication of air, gas and insects. Therefore, it can play an important role in maintaining a pleasant and hygienic residential environment by blocking the backflow of odor or insects from the conduit.
