Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to a pressure vessel with an over-pressure protection function. Background Art

[0002] A pressure vessel is a closed container that can withstand pressure. Pressure vessels are widely used and play an important role in many sectors such as industry, civil, military and many fields of scientific research. Because the working environment needs to withstand high pressure and extreme environment, pressure vessels are generally installed with safety accessories such as pressure gauges, liquid level gauges and safety valves.

[0003] For example, Chinese patent CN220354461U discloses a pressure vessel with an overpressure protection function, comprising: a container body; a pressure relief groove, the bottom of which is connected to the top of the container body, a dust plate is arranged inside the pressure relief groove, and exhaust grooves are fixedly connected on both sides of the pressure relief groove; a connecting rod, the bottom end of which is fixedly connected to the top of the container body, a sliding plate is slidably connected to the outer surface of the connecting rod, a sliding rod is slidably connected to the inside of the sliding plate, a sealing plug is fixedly connected to the bottom of the sliding rod, and a pressure spring is arranged between the top of the sealing plug and the bottom of the sliding plate. The pressure vessel with an overpressure protection function provided by the utility model has an automatic pressure relief function, which prevents the internal air pressure of the container body from being too high and causing an explosion, thereby reducing safety hazards.

[0004] However, when the pressure vessel with overpressure protection function stores toxic gas or liquid, the toxic gas or liquid may leak during the pressure relief process, and the sealing of the pressure relief groove cannot completely prevent the natural leakage of the toxic gas or liquid.

[0005] Based on this, the utility model designs a pressure vessel with an overpressure protection function to solve the above problem. Utility Model Content
