Pipeline anti-methane device

Abstract

A pipeline biogas-proof device is arranged between a first water pipe and a second water pipe and comprises a body and at least an anti-reverse unit. The body is hollow and comprises a first end, a second end which is opposite to the first end in the first axial direction, and a chamber that communicates the first end and the second end. The first end is connected to the first water pipe. The second end is connected to the second water pipe. The anti-reverse unit is arranged between the first end and the second end of the body. The anti-reverse unit comprises a first baffle plate and a second baffle plate. The first baffle plate comprises a first connection part and a first baffle edge. The second baffle plate comprises a second connection part and a second baffle edge. The first baffle edge and the second baffle edge respectively correspond to a first axial direction and a second axial direction, wherein the first axial direction is perpendicular to the second axial direction so that the first baffle edge and the second baffler edge is staggered so as to baffle the biogas.

Description

technical field [0001] The invention relates to a pipeline device, in particular to a pipeline biogas prevention device arranged in a drainage pipeline. Background technique [0002] General domestic sewage, such as the discharge of condensate water from air-conditioners, laundry water, or bath water, is discharged directly through drainage pipes or first discharged into temporary storage tanks, and then continues to be discharged to the sewer outside the house. Such a discharge method is likely to make the methane in the sewer seep into the house along the drainage pipe, causing the smell of methane to permeate the house and affecting the living quality. If the biogas seeps along the drainage pipe and goes home to the home air conditioner, the biogas contains sulfides that will chemically react with the condensing copper pipe of the air conditioner, which will cause the condensing copper pipe to blacken and corrode in the long run. In more serious cases, it will also cause...

AI Technical Summary

Problems solved by technology

If it is more serious, it will also cause the condensing copper pipe to break and cause the refrigerant to leak out, thereby affecting the performance of the air conditioner

[0003] In order to solve the above problems, the existing self-sealing floor drain disclosed in Taiwan's new patent No. M271893 is just such a mechanical swing structure, which is easy to lose its function due to dirt or corrosion, causing users to need time-consuming and laborious regular replacement.

Furthermore, for the convenience of replacement, it must also be installed outside the decoration in the form of an exposed tube, which is not beautiful in use.
