Description

Technical Field

[0001] This utility model specifically relates to the field of pressure vessel technology, and more specifically to an anti-loosening assembled pressure vessel. Background Technology

[0002] Pressure vessels are closed devices that hold gases or liquids and bear a certain pressure. Their scope is defined as: stationary and mobile containers for gases, liquefied gases, and liquids with a maximum working pressure greater than or equal to 0.1 MPa (gauge pressure) and a pressure-volume product greater than or equal to 2.5 MPa·L; gas cylinders for gases, liquefied gases, and liquids with a standard boiling point equal to or lower than 60℃ with a nominal working pressure greater than or equal to 0.2 MPa (gauge pressure) and a pressure-volume product greater than or equal to 1.0 MPa·L; oxygen chambers, etc.

[0003] Chinese Utility Model Publication No. CN 117307713 A discloses an assembled anti-loosening pressure vessel, including a container body and a container cover. The container cover is threaded onto the top of the container body. It also includes an anti-rotation mechanism, which includes a ratchet, a pawl, and a pawl shaft. The ratchet is fixedly mounted on the container cover. The pawl shaft is provided on the side wall of the container body. The axis of the pawl shaft is parallel to the axis of the container body. The pawl is slidably mounted on the pawl shaft by a torsion spring. The pawl has the freedom to move axially along the pawl shaft. When the torsion spring is in its normal state, the pawl is adapted to the ratchet groove of the ratchet to restrict the reverse rotation freedom of the ratchet. The screw tightening rotation direction of the container cover is the same as the forward rotation direction of the ratchet, thus restricting the reverse rotation freedom of the container cover.

[0004] The aforementioned assembled anti-loosening pressure vessel has a fixed internal pressure and volume that cannot be changed during use, and it cannot buffer pressure. To address this, we provide an anti-loosening assembled pressure vessel that allows the pressure and volume to be adjusted by pushing the bottom of the compensating cylinder with an upward-pushing cylinder. It is also easy to assemble and effectively overcomes the aforementioned problems. Utility Model Content
