Embodiment Construction

[0008] The present invention will be further described below in conjunction with drawings and embodiments.

[0009] As shown in Figure 1, the present invention is made of a plastic material with good elasticity, aging resistance, abrasion resistance, acid and alkali corrosion resistance and smooth surface, which is opened at the bottom and has a lip edge 1 and an elastic honeycomb 2 , tube 3, tube top 4, suspension bar 5, integral curved check valve of sleeve fixing ring 6, first install sleeve fixing ring 6 and then flush the valve into the sewer pipe, and generate inertial micro-pressure when flushing, so that The valve is quickly squeezed and bent, leaning against the side of the suspension bar, allowing most of the pipeline channels to ensure that the hardest stool and flushing dirt flow through. After the water is stopped, the inertial micro-pressure disappears. In the enhanced honeycomb 2 and Under the action of the elastic force of the barrel 3, it immediately returns t...

Abstract

A deformable plastic check valve for sewer pipe is prepared from the elastic plastics resisting to ageing, acid and alkali, and has the elastic lower mouth with honeycomb structure, closed top end with a pull-up ring, and reinforcing rings on its external circumference. When water is flushed down, it isdeformed from draining the water and then elastically restored to its original shape. Its advantage is high sealing performance.

Description

technical field [0001] The invention relates to a flushing deformation return check air valve for building sewer pipes. Background technique [0002] At present, the sealing of the stool sewer pipe is guaranteed by the backwater bend. If it is not used for a long time, when the water evaporates, mosquitoes, flies and odor will enter the room, affecting indoor hygiene. Contents of the invention [0003] The purpose of the present invention is to provide a check air valve that is easy to install under the entrance of the sewer pipe, so as to ensure that the stool and flushing dirt can be discharged along the water, and can stand upright and seal the pipe. clogged pipes. It can be sealed for a long time after the backwater bend dries up. [0004] The object of the present invention is achieved in this way, by using plastic materials with good elasticity, aging resistance, acid and alkali corrosion resistance and smooth surface, it is made into a cylindrical shape with honey...
