[0002] Petrochemical industry refers to the industry that uses hydrocarbon compounds such as petroleum and natural gas as raw materials to produce various organic chemicals and synthetic materials through chemical processes. Petrochemical gas usually refers to the gas produced from the petrochemical production process.

[0003] Gas leaks may cause fires, explosions and other safety accidents, and may cause air pollution and impact the environment. Therefore, leaks need to be discovered and dealt with in a timely manner to ensure the safety of the production process. Gas leak detectors are needed to monitor gas leaks.

[0026] The working principle of this utility model:

[0027] When it is necessary to remove the leakage alarm 1, the disassembly rod 601 is pulled to the left by manpower and the short rod 602 is moved to the left. The short rod 602 will rotate the rotating rod 603 during the movement, so that the bottom of the rotating rod 603 will rotate clockwise with the supporting block 604 as the center. The rotating rod 603 will move the slider 502 upward and the positioning block 501 upward during the rotation, so that the positioning block 501 is moved out from the inside of the plug-in block 3. At this time, the leakage alarm 1 can be moved forward and out of contact with the mounting seat 201, so as to realize the removal of the leakage alarm 1. When it is necessary to fix the leakage alarm 1 to the mounting seat 201, the fixing block 105 will drive the plug-in block 3 to be plugged and connected with the inside of the mounting groove 203. When the disassembly rod 601 moves to the left, The moving block 605 moves to the left and deforms the squeezing spring 606. After the disassembly rod 601 is released, the elastic action of the squeezing spring 606 causes the moving block 605 to drive the disassembly rod 601, the short rod 602 and the rotating rod 603 to rebound to their original positions. When the slider 502 moves upward, the two tension springs 503 are deformed. When the disassembly rod 601 is released, the elastic action of the two tension springs 503 causes the slider 502 to drive the positioning block 501 to rebound to the inside of the plug-in block 3, thereby connecting and fixing the leak detector 1 to the mounting base 201. The leak detector 1 monitors whether the gas is leaking through the sensor 102. The parameters of the leak detector 1 are set through the controller of the leak detector 1. When a gas leak is detected, the alarm light 104 will make a sound and light up.
