Description

Technical Field

[0001] The utility model relates to the technical field of gas transportation, and more specifically, to a pressure alarm for industrial gas transportation. Background Art

[0002] There are many kinds of gases, which can be roughly divided into industrial gases and special gases. Industrial gases are called the "blood" of industry. With the rapid development of the economy, industrial gases, as one of the basic industrial elements of the national economy, have become increasingly important in the national economy. Bottled or canned transportation is the most common choice for industrial gases during transportation. During transportation, the internal gas pressure needs to be detected to avoid safety accidents. Therefore, a pressure alarm for industrial gas transportation is needed. The pressure alarm for industrial gas transportation described in the publication number (CN216349334U) is provided with a connecting pipe on one side of the alarm body, so that the connecting pipe is conveniently connected to the gas outlet of the tank for transporting industrial gas, and the gas pressure detector is convenient for detecting the gas pressure to ensure the stability of the industrial gas during transportation. At the same time, the first sealing ring and the second sealing ring are provided inside the connecting pipe to ensure the tightness of the connection between the connecting pipe and the gas, prevent the gas from leaking and causing danger, and affect the detection result of the device. Arc plates are provided on the upper and lower parts of the connecting pipe, and screws are provided on the upper and lower parts of the connecting pipe to connect with the arc plates, so that the screws are convenient to rotate to drive the arc plates to move, thereby ensuring the stability of the connection.

[0003] When the above device is in use, it is prevented from falling due to unstable connection, which would affect the detection of internal gas pressure and reduce the labor intensity of the staff. When the pressure value of the industrial gas reaches a certain higher pressure value, the controller controls the buzzer to start and the indicator light to flash, and transmits the pressure signal to the staff to remind the staff to deal with it in time, thereby ensuring the safety of industrial gas transportation, extending the service life of the device, and making the device more applicable. However, when the pressure alarm of the above device fails, it is inconvenient to disassemble it, and the locking piece arranged at the connection between it and the external air duct has a complex structure and is easily damaged, which can easily cause air leakage at the connection of the air duct.
