Embodiment 1

[0025] 1. Make a groove on the wall through which the gas pipe behind the gas meter passes. The groove should meet the requirements of 2.2.19 in the "Code for Construction and Acceptance of Urban Gas Indoor Engineering" CJJ94-2003, and the width is the outer diameter of the pipe plus 20 Mm

[0026] 2. Pave the gas pipeline in the groove, and use PE aluminum-plastic composite pipe for the gas pipeline. A trough-type hot-dip galvanized sheet protective cover is provided, and the enclosed space of the aluminum-plastic pipe in the cover is filled with refractory materials without gaps.

[0027] 3. Install the wall-buried stove front valve in the groove. One end of the gas pipeline in the groove is connected to the gas meter, and the other end is connected to the special stove front valve installed in the groove, and the other end of the stove front valve is connected to a hose , A buried wall sleeve is set at the outlet of the front valve of the stove to facilitate the connection of t...

Embodiment 2

[0030] In step two, it also includes: arranging effective partition materials for the parts where the buried pipe penetrates the floor and the wall. For example, the middle of the casing is filled with a flexible sealing material, and the two ends are smoothed with cement mortar to prevent gas blow-by at each gas location.

Embodiment 3

[0032] The following steps can be added to the steps of embodiment 1:

Abstract

The invention relates to a new safety burying wall construction method for indoor fuel gas pipeline and accessories. It includes such characteristic of making a groove on the wall body where the fuel gas pipeline after a fuel gas meter passes through, laying the fuel gas pipeline in the groove, arranging a groove thermal galvanized plate protection cover outside the fuel gas pipeline, arranging a wall buried kitchen range front valve in the groove, connecting one end of the fuel gas pipeline in the groove with the fuel gas meter and connecting the other end with the front valve. The advantage lies in that it can effectively avoid the accident of fuel gas leakage.

Description

Technical field [0001] The invention belongs to the field of construction methods for indoor gas pipelines and accessories. technical background [0002] With the development of urban gas industry, a large number of residential, factory, commercial, public buildings and other users use gas, which has effectively promoted the development of the national economy and the improvement of people's living standards. Indoor gas pipeline equipment is an important facility for gas transmission and distribution. For a long time, the method of laying along the wall has been widely used in China, which has been completely unable to meet the requirements of economic development and the improvement of people's living standards. For example, the installation of indoor gas pipelines still uses straight-welded water gas steel pipes, and there are many shortcomings when adopting the wall-mounted surface installation process: there are many threaded joints, which are easy to corrode, break, and leak...
