Description

Technical Field

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

[0002] Pressure vessels play a very important role in various industries, such as petrochemical and energy industries, scientific research, military industry, and machinery manufacturing. Pressure vessels are usually used to contain gas or liquid and other items and can withstand greater pressure. However, the pressure that a pressure vessel can withstand is limited. If the pressure of the pressure vessel is increased without restriction, it will cause cracks in the pressure vessel, and in severe cases, it will lead to extremely dangerous situations such as explosions. To solve this problem, the pressure vessel must be depressurized.

[0003] After searching, the prior art, publication number CN117386810A discloses a pressure vessel with an automatic pressure relief function, including a pressure tank, the upper end of the pressure tank is slidably connected to an end cap, an automatic pressure relief mechanism is provided inside the end cap, a screw is mounted on the middle portion of the upper end of the end cap via a bearing, a threaded ring is threadedly connected to the outer side of the screw, an anti-loosening mechanism is provided inside the end cap, an auxiliary limiting mechanism is provided on the end cap, the outer side of the threaded ring is fixedly connected to multiple evenly distributed drive frames, the outer side of the end cap is fixedly connected to multiple evenly distributed articulated frames, the outer side of each articulated frame is hinged to a clamping frame, and the upper end of the screw is fixedly connected to a handwheel. The present invention relates to a pressure vessel with an automatic pressure relief function, which has the characteristics of being able to automatically relieve pressure under various pressures and having a stable installation of the end cap.

[0004] However, the device and the prior art still have the following defects:

[0005] Traditional pressure vessels generally release pressure by directly opening the pressure relief valve. This pressure relief method is dangerous. The direct discharge of high-temperature and high-pressure gas may injure the operator. In addition, directly opening the pressure relief valve will cause the pressure vessel to lose pressure quickly, which will affect the normal use of the pressure vessel. Utility Model Content
