Description

Technical Field

[0002] As a commonly used industrial gas, acetylene is widely used in fields such as welding, cutting, metal processing, and petrochemical industry. However, acetylene has the characteristics of being flammable and explosive. Once leakage occurs during the production process, it is extremely easy to cause fire or explosion accidents, posing a serious threat to the safety of personnel and equipment. Therefore, developing an efficient and reliable acetylene gas leakage detection device is of great significance for ensuring industrial production safety.

[0003] The light-controlled acetylene gas leakage detection device with the reference publication number of CN207050922U includes a suction cup head, a detection unit, a dry battery, and an alarm lamp. The suction cup head is located at the mouth of the acetylene storage tank. The suction cup head is connected to the detection unit through an air flow pipe. The alarm lamp and the dry battery are connected through a pressure switch. When the pressure switch is under pressure, the alarm lamp is in the off state. The detection unit includes a conical ball valve, acetone solution, and a floating ball. The floating ball can contact the switch under the action of the acetone solution. The alarm lamp can both emit light and make a sound. Compared with the traditional detection device, this light-controlled acetylene gas leakage detection device can timely detect the leakage of acetylene gas and avoid the danger of explosion caused by the leakage of acetylene gas. According to the above, although this device can be well applied, it is usually not convenient to adjust the position of the detection component, which makes the detection range of this device have certain limitations, thus affecting the leakage detection accuracy of this device for acetylene gas, and often troubles the users.
