Description

A natural gas leakage alarm device

technical field

The utility model relates to the technical field of natural gas pipelines, in particular to a natural gas leakage alarm device.

Background technique

Natural gas is a gaseous fossil fuel mainly composed of methane. It mainly exists in oil fields and natural gas fields, and a small amount comes from coal seams. Natural gas is also buried in underground closed geological structures like crude oil, and some are stored in the same layer as crude oil. For natural gas stored in the same layer as crude oil, it will be extracted together with crude oil. The main use of natural gas is as fuel, which can be used to produce carbon black, chemicals and liquefied petroleum gas. Propane, butane and butane produced from natural gas Alkane is an important raw material for modern industry. Natural gas is mainly composed of a mixture of gaseous low-molecular hydrocarbons and non-hydrocarbon gases. With the accelerated implementation of natural gas price reforms, the "13th Five-Year Plan" vigorously promotes the gradual approaching of natural gas development expectations, and the recent cooling of natural gas. With the substantial increase in usage, the development of natural gas will usher in a historic opportunity.

At present, with the development of the country, the use of natural gas is also very common. However, when natural gas pipelines are transported, due to the poor sealing of the interface, natural gas leakage will cause a great impact. However, the common natural gas leakage alarm device is installed at present. It is often troublesome to look up, and with long-term use, it is easy to cause damage to internal parts, and it is troublesome to maintain. Therefore, in order to solve this series of problems, we have proposed an automatic feeding mechanism for sheet metal shearing machines to solve the problem
