Natural gas pipeline switch safety protection device

Abstract

The invention discloses a safety protection device for a switch of a natural gas pipeline, which comprises a rectangular casing, and gas inlet pipes and gas outlet pipes are respectively arranged on the left and right sides of the upper part of the rectangular casing. The safety protection device for a natural gas pipeline switch has a simple structure and is easy to install , it occupies a small space when used, and can play a good role in safety protection for natural gas users. The use of the display enables the present invention to display the concentration of natural gas in the surrounding environment and the amount of natural gas used in real time, which is convenient for users. When a fire occurs, the flame arrester can effectively prevent the combustion of natural gas in the outlet pipe, the natural gas concentration detector can monitor the content of natural gas in the surrounding gas in real time, and the temperature sensor can monitor the temperature of the surrounding gas. The gas machine can discharge the surrounding air together with the natural gas to the outside, which can effectively prevent the occurrence of fire.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline switch safety protection settings, in particular to a natural gas pipeline switch safety protection device. Background technique [0002] Natural gas is a high-quality gas fuel, which has the advantages of cleanness, high calorific value, convenient use, and non-toxicity. However, if used improperly, serious consequences of fire, explosion and suffocation will occur. The main component of natural gas is methane (CH4), and the explosion limit is 5%-15%. With the rapid development of the economy, natural gas and liquefied petroleum gas have entered thousands of households. While it is convenient for people's lives, frequent gas accidents cause lingering fears. Fire accidents have the characteristics of large social impact, large economic losses, easy death and injury, easy explosion or deflagration, and fast fire development. The main cause of gas fires is the fire caused by improper...

AI Technical Summary

Problems solved by technology

The existing natural gas pipeline switch safety protection device often cannot prevent the occurrence of fire when natural gas leaks, so a new type of natural gas pipeline switch safety protection device is urgently needed to ensure that natural gas is safer to use, and at the same time, it can handle it in time when natural gas leaks , in case of fire
