Technical Field

The invention relates to the technical field of pressure containers, in particular to a gas leakage self-display pressure container.

Background

The pressure container is a closed device which contains gas or liquid and bears certain pressure. In order to implement scientific management and safety supervision and inspection more effectively, pressure vessels are divided into three categories according to working pressure, medium hazard and the effect of the medium hazard in production in the pressure vessel safety supervision regulations in China.

A pressure vessel is a closed vessel that can withstand pressure. The pressure container has wide application range, and has important position and function in many departments of industry, civil use, military industry and the like and many fields of scientific research. Among them, the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels, in order to be used in the chemical industry and the petrochemical industry at most. The pressure vessel is in the chemical and petrochemical field, mainly used for the technological process such as heat transfer, mass transfer, reaction, etc., and store, transport the gas or liquefied gas with pressure; it is also widely used in other industrial and domestic applications, such as air compressors. Auxiliary machines (such as a cooler, a buffer, an oil-water separator, a gas tank, an evaporator, and a liquid coolant tank) of various special compressors and refrigeration compressors belong to pressure vessels.

The pressure vessels used for containing gas are easy to leak, although most of the pressure vessels are provided with pressure gauges for monitoring pressure, the pressure gauges are difficult to monitor in time for slight gas leakage, and the leakage part cannot be accurately positioned, so that certain loss is caused when a certain amount of gas is leaked.
