A kind of one-way valve type house drainage system with anti-gas backflow

Abstract

This application relates to the technical field of house drainage, and discloses a one-way valve-type house drainage system that prevents gas backflow, which includes a bathroom floor with installation holes, a floor drain installed in the installation hole, and a drainage system buried inside the bathroom floor. There is a built-in cavity connected to the installation hole inside the bathroom floor, and a temporary storage box with an open top is set inside the built-in cavity. The floor drain is located above the opening of the temporary storage box, and the bottom of the temporary storage box passes through the anti-backflow component Connect to drain. The temporary storage box of the present application collects the water flow and enters the drainpipe through the anti-backflow component. The anti-backflow component can prevent the odorous gas inside the drainpipe from backflowing, improve the air cleanliness of the bathroom space, and at the same time prevent the water flow from being crowded at the drainpipe. As a result, the water flow at the floor drain is not smooth, and the drainage efficiency of the bathroom floor is improved.

Description

technical field [0001] The present application relates to the field of house drainage, in particular to a one-way valve type house drainage system of anti-gas backflow type. Background technique [0002] In order to facilitate drainage, the house is usually equipped with a floor drain. The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the house, especially the bathroom, it is very important for drainage efficiency and space odor control. [0003] The floor drains and drainage pipes of bathroom fittings are often washed by organic substances such as shower gel and shampoo. Since the floor drain itself does not have a sealing function, it only relies on the turning design of the pipe connection to remove the odor, and the pipe is long and the water flow is crowded, resulting in low drainage efficiency and poor odor removal effect, resulting in the overflow of odor gas at the floor ...
