Gas distribution device

Abstract

The embodiment of the invention discloses a gas distribution device. The gas distribution device comprises a first mother pipe and a second mother pipe; a first pressure detection component and a first safety pipeline are arranged on the first mother pipe; the second mother pipe communicates with the first mother pipe through a first pressure reducing pipeline or a second pressure reducing pipeline, the first pressure reducing pipeline is provided with a first pressure reducing valve, the second pressure reducing pipeline is provided with a second pressure reducing valve, and the second mother pipe is provided with a second pressure detection component and a second safety pipeline; and the first mother pipe is connected with multiple gas source pipelines used for supplying gas to the first mother pipe, and the second mother pipe communicates with multiple gas using pipelines. By means of the gas distribution device, the working condition that gas of multiple different gas sources is supplied can be met, after the gas of the gas sources is subjected to pressure reducing through any one of the first pressure reducing pipeline and the second pressure reducing pipeline which serve as standby pipelines of each other, the gas is conveyed to the second mother pipe, the corresponding gas using pipelines are selected through the second mother pipe to output using gas for gas using equipment, and the process is simple, safe, reliable, flexible and diversified.

Description

technical field [0001] The invention relates to the technical field of industrial gas distribution, in particular to a gas distribution device. Background technique [0002] With the development of science and technology, modern industrial production and manufacturing technology has also made great progress, but gas still plays an indispensable role in the industrial field, such as chemical industry, medicine, metallurgy, electronics, energy and other fields need hydrogen, oxygen, Various gases such as nitrogen and argon. [0003] Generally speaking, industrial gas equipment has different requirements for the pressure and flow rate of different gases, especially the pressure requirements are generally quite different from the pressure of the gas source. Gas supply to equipment generally needs to supply gas to industrial gas equipment through a gas distribution device. At present, the gas distribution devices used in the industrial field are generally aimed at a single gas,...

Problems solved by technology

At present, the gas distribution devices used in the industrial field are generally aimed at a single gas, that is, a set of gas distribution devices corresponds to one gas source, which can supply gas to one or more gas-consuming equipment, and cannot meet the gas supply requirements of multiple gas sources. Faced with the working conditions of multiple gas sources, it is required to configure multiple sets of gas distribution equipment, which has problems such as high equipment cost and complicated control.
