Embodiment 1

[0024] 1. Make a groove on the wall where the gas pipeline passes behind the gas meter. 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 pipeline plus 20 mm;

[0025] 2. Lay the gas pipeline in the groove, and the gas pipeline adopts PE aluminum-plastic composite pipe. A trough-type hot-dip galvanized sheet protection cover is installed, and the enclosed space of the aluminum-plastic pipe inside the cover is filled with refractory materials without gaps.

[0026] 3. Set the front valve of the buried wall stove 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 front valve installed in the groove. The other end of the front valve of the stove is connected to the rubber hose. , A buried wall sleeve is set at the outlet of the stove valve to facilitate the connectio...

Embodiment 2

[0030] In step 2, it also includes: installing effective partition materials at the parts where the buried pipes pass through the floor and through the walls, such as filling the middle of the casing with flexible sealing materials, and smoothing the ends with cement mortar to prevent gas from blowing out at various gas-using parts.

Embodiment 3

[0032] On the step of embodiment 1, following steps can be added:

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 of indoor gas pipelines and accessories. technical background [0002] With the development of urban gas business, 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, surface installation along the wall has been widely used in China, which can no longer meet the requirements of economic development and improvement of people's living standards. For example, the installation of indoor gas pipelines still adopts straight welded seam water gas steel pipes, and there are many disadvantages when adopting the process of surface installation along the wall: there are many threaded joints, easy to corrode, easy to damage, easy to leak...
