CN201057368Y - An explosion-proof device for gas pipeline leakage - Google Patents

Abstract

The utility model relates to an anti-explosion device used in fuel gas pipeline leakage, pertaining to the anti-explosion device for fuel gas transmission. The utility model comprises a shell and is characterized in that anti-explosion boards and pipes are arranged on the shell; the pipe on which a valve is installed runs into the shell and the pipe inside the shell is provided with a blast nozzle while the pipe outside the shell is provided with a depressurization pipe. The utility model blocks and stops backfire inside the pipe during fuel gas leakage to prevent explosion and reduce personal injury and property loss. The utility model has simple structure, convenient installation and reliable use.

Description

An explosion-proof device for gas pipeline leakage

Technical field:

The utility model relates to an explosion-proof device for pipeline transportation of combustible gas.

Background technique:

In the process of pipeline transportation of combustible gas, once the combustible gas leaks, it will burn or explode when encountering an open flame. Even if the valve is closed, the gas with backfire cannot be cut off instantly, and the backfire will continue to burn along the combustible gas transmission pipeline. The explosion caused personal injury and property damage to people.

Invention content:

The utility model aims to provide a device which can insulate the flame and cut off the backfire in the pipeline when the combustible gas leaks.

The technical solution for realizing the utility model is: comprising a shell, an explosion-proof plate and a pipeline are arranged on the shell, a valve is installed on the pipeline, the pipeline passes through the shell and enters the shell, an air nozzle is arranged on the pipeline in the shell, and the pipeline outside the shell Install the decompression tube on it.

Put water into the shell of the utility model, the gas enters the water in the shell through the pipeline and the air nozzle, and the gas emerges intermittently in the form of bubbles. At this time, the tempering of the gas has been eliminated. The exhaust pipe is discharged, so that the occurrence of combustion and explosion is avoided. The utility model has the advantages of simple structure, convenient installation and reliable use.
