Description

Technical Field

[0001] The utility model relates to the technical field of gas corrosion tests, in particular to a large-scale mixed gas corrosion test device. Background Technique

[0002] Gas corrosion refers to the corrosion that occurs when a metal reacts only with a gas corrosive agent on the metal surface without any liquid phase conditions, that is, the corrosion process that occurs when a metal material is completely free of moisture condensation on the surface. At present, people mostly use a gas corrosion test chamber to conduct gas corrosion tests.

[0003] Chinese Patent CN215953312U discloses a gas corrosion test chamber, including a box body. One side of the front surface of the box body is installed with a double-layer protection door through a hinge structure. A sealing ring is installed on the outer side of the double-layer protection door. An adjusting mechanism is installed inside the box body. One side of the outer wall of the box body is installed with a sealing mechanism. By means of the sealing ring on the outer side of the double-layer protection door, the sealing effect of the device can be increased. The oil inside the storage box can prevent gas from leaking out at the connection between the conveying pipe and the box body. At the same time, the detector can detect the connection between the conveying pipe and the box body. When the detector detects gas leakage, it will transmit the data to the control box, which can timely remind people to deal with it, thereby improving the practicability of the device; by the heating tube emitting heat and the atomizer atomizing water and spraying it out through the nozzle, corrosion resistance tests can be carried out on products under different conditions, which is convenient for personnel to use, and thus the functionality of this device can be improved.

[0004] When the above patent is in use, the corrosive gas in the box body cannot be circulated, the fluidity of the corrosive gas in the closed space is poor, and the contact with the test piece is limited, resulting in a slow test efficiency. Therefore, in view of the above current situation, there is an urgent need to develop a large-scale mixed gas corrosion test device that is convenient for circulating the corrosive gas in the test chamber, making the contact between the corrosive gas and the test piece more sufficient, and improving the test efficiency, so as to overcome the deficiencies in current practical applications and meet the current requirements. Summary of the Utility Model
