Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of storage tank safety protection, especially relates to a mechanical pressure relief protection device for storage tank safety accessory detection. BACKGROUND

[0002] The existing storage tank faces the risk of pressure change when storing various substances (such as liquid, gas, etc.), and if the internal pressure is too high and cannot be relieved in time, it may cause the storage tank to rupture, explode and other serious accidents. Therefore, a mechanical pressure relief protection device, i.e. a safety valve, is generally provided on the storage tank. Its main function is to automatically open when the internal pressure of the storage tank exceeds the preset safety value, releasing excess pressure to prevent the storage tank from rupturing, exploding and other safety accidents due to excessive pressure.
