Description

Technical Field

[0001] The utility model relates to the technical field of safety protection, in particular to a gas storage tank safety discharge device. Background Art

[0002] A gas storage tank is a device specifically designed to store gas and stabilize system pressure. It can be categorized as high-pressure, low-pressure, or atmospheric pressure depending on the pressure it can withstand. Depending on the material used, it can be classified as carbon steel, low-alloy steel, or stainless steel. A gas storage tank (pressure vessel) generally consists of a cylinder, head, flange, nozzle, sealing element, and support, among other components. It is categorized by the pressure it stores. The former is divided into wet and dry types, typically serving as a simple pressure vessel. While air compressor gas storage tanks have long been considered a relatively safe form of special equipment, they also carry certain risks. Failures in design, manufacturing quality, installation standards, operation, and management that fail to meet regulatory requirements can create hidden dangers and potentially lead to serious accidents, resulting in casualties and equipment damage. Gas storage tanks must be registered before installation. After installation, they must obtain a pressure vessel license and undergo regular inspections in accordance with special equipment requirements. Only after passing the inspection and obtaining an inspection report can they be put into use. Gas tanks must be regularly inspected based on their pressure level and service life. Gas tanks that have not passed these inspections must not be used. The volume and pressure of gas tanks must comply with design standards and should not be randomly assigned. Each air compressor must be equipped with a gas tank. Gas tanks at ground-based air compressor stations should be protected from direct sunlight, have inspection holes, and be regularly cleaned of grease and dirt.

[0003] In the prior art, there are certain defects in the anti-leakage technology of gas storage tanks. Leakage may occur during the high-pressure continuous transmission process or the high-pressure storage process. Therefore, the utility model proposes a gas storage tank safety discharge device.
