Household gas pipe

Abstract

The invention provides a household gas pipe, which includes a gas pipe body, the gas pipe body is wave-shaped along its axial direction, and a wave-shaped gas passage is arranged inside the gas pipe body, and the gas pipe body In the cross-section, from inside to outside, there are polyethylene layer A, aluminum layer, polyethylene layer B, fireproof mud layer and self-inspection film layer. The middle part of polyethylene layer B is embedded with a layer of steel mesh A, and the outer side of polyethylene layer B is A layer of steel wire mesh B is wound, and the wavelength of the gas pipe body is 2.8-3.2 times the wave height. The gas pipe allows users to judge whether there is a gas leak, and prevents insects from biting the pipe, thereby greatly improving the safety performance of the gas pipe.

Description

technical field [0001] The invention relates to a gas pipe, in particular to a household gas pipe. Background technique [0002] With the promotion and popularization of natural gas, whether it is urban or rural, natural gas is now widely used as the main fuel. However, as a fuel, natural gas itself is colorless and odorless, and its density is lower than that of air. When it leaks, it usually runs upwards. When the concentration of natural gas in the air reaches 5%-15%, it will explode when it encounters an open flame. Due to the colorless and odorless characteristics of natural gas , so it is difficult to find its leakage, which often leads to fire accidents. Therefore, the safe use and protection of household gas has become the top priority. Most of the natural gas accidents that occur today are caused by gas leakage, but the user did not find out in time, and then the operation caused the accident. The reason for the gas leakage is generally due to the aging of the pipe...

Problems solved by technology

However, as a fuel, natural gas itself is colorless and odorless, and its density is lower than that of air. When it leaks, it usually runs upwards. When the concentration of natural gas in the air reaches 5%-15%, it will explode when it encounters an open flame. Due to the colorless and odorless characteristics of natural gas , so it is difficult to find its leakage, which often leads to fire accidents

Therefore, the safe use and protection of household gas has become the top priority. Most of the natural gas accidents that occur today are caused by gas leakage, but the user did not find out in time, and then the operation caused the accident. The reason for the gas leakage is generally due to the aging of the pipeline. , Cracks appear after being folded

The gas leak detection device used as a home gas leak detection device can only send an alarm by detecting the gas concentration in the air after the gas leak, and take a series of measures. The gas leak detection device is the last barrier of gas safety. It has a The problem of sensitivity, if there is a problem in the detection, but people do not find it in time, then the next series of operations will easily cause accidents

At present, in order to avoid gas leakage, for gas pipelines, the first is to develop and replace the pipeline material to prolong the service life of the pipeline, and then to improve its bending resistance, and to add a layer of metal material to prevent being bitten by insects, but again Good materials also have their service life. In daily life, people generally do not pay attention to regular replacement, and there are still certain safety hazards. This is the deficiency of existing technologies.
