Abstract

The utility model discloses an odour-proof return flow tee, which comprises a main pipe (1) and a branch pipe (2), wherein the branch pipe (2) is vertically communicated with the main pipe (1). The utility model is characterized in that The point of the inner opening (3) of the branch pipe (2) is movably connected with a seal cover (4), and the outer diameter of the seal cover (4) is bigger than the inner diameter of the inner opening (3) of the branch pipe (2). The upper end of the seal cover of the utility model is in movable connection and natural sagging, and the flowing water of the branch pipe can thrust aside the upper end of the seal cover. When superincumbent flowing water passes through the main pipe, caused odour airflow thrusts the seal cover, the branch pipe is sealed tightly, the odour can not enter the branch pipe, and odour return flow can not be caused, either.

Description

A kind of anti-peculiar smell backflow threeway

Affiliated technical field

The utility model belongs to a kind of hygienic environment-protecting device, is a kind of tee pipe fitting that prevents that peculiar smell from refluxing particularly.

Background technique

People can often run into sewerage peculiar smell backflow phenomenon and be commonly called as anti-flavor in daily life, working environment) phenomenon, particularly indoor environment, contaminated air stinks to high heaven, and is the problem of family or unit worries for many years, and does not have the good method of preventing and treating.The generation of sewerage peculiar smell backflow phenomenon, its reason are that drain pipe, blow-off line and pollution discharge pond link to each other with Rest Room, toilet, and do not have effectively control peculiar smell reflux, cause a large amount of harmful gases directly to enter huge numbers of families.The normally used protection method of people is " floor drain " method just, and it is untimely that the deficiency of this method is to add water, and peculiar smell is refluxed, and particularly summer, need add water 2～3 times every day, otherwise indoorly just can be full of foul smell.

Summary of the invention

The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of tee pipe fitting that prevents that peculiar smell from refluxing is provided, and it is simple in structure, and is durable in use, and using effect is good.

For reaching above-mentioned purpose, the utility model is taked following technological scheme: the utility model includes: the person in charge, arm, arm and person in charge's vertical connection, it is characterized in that: the inner opening place activity at arm is connected with capping, and the capping external diameter is greater than arm inner opening internal diameter; Capping is connected in the upper edge of arm inner opening by the connecting shaft activity.

The utility model is taked technique scheme, has following beneficial effect: the person in charge of the present utility model is connected on the public following water main pipe, and arm connects with waste pipe in the family room.When domestic water is discharged, flow among the person in charge through waste pipe and arm, the capping upper end is movable to be connected, and sagging naturally, arm flowing water can be washed it open; Top-down flowing water is arranged through out-of-date and be responsible for, the peculiar smell air-flow that causes can impact capping, and arm is shut in capping, and peculiar smell can not enter arm, does not also just cause the peculiar smell backflow.
