Pipeline biogas-proof device

Abstract

A pipeline marsh gas prevention device is arranged between a first water pipe and a second water pipe and comprises a body and at least one anti-reflux unit. The body is hollow and comprises a first end, a second end opposite to the first end in a first axial direction, and a chamber communicated from the first end to the second end, wherein the first end is connected with the first water pipe, and the second end is connected with the second water pipe. The anti-reflux unit is arranged between the first end and the second end of the body and comprises a first baffle and a second baffle, wherein the first baffle is provided with a first connecting part and a first blocking edge, and the second baffle is provided with a second connecting part and a second blocking edge. The first blocking edge and the second blocking edge are arranged in a staggered mode corresponding to the first axial direction and a second axial direction perpendicular to the first axial direction, and therefore the effect of gas prevention is realized.

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...

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.
