Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline detection, in particular to a gas pipeline detection alarm device. Background Art

[0002] Natural gas is the main fuel for gas boilers, and its main component is methane. During the operation of the gas boiler, natural gas is input into the combustion chamber through pipelines. However, the boiler's gas pipelines usually have joints, valves, etc. Gas leaks may occur at these pipeline joints, so the joints or valves need to be inspected.

[0003] The prior art provides a gas boiler natural gas pipeline leak detection and alarm device (Announcement No. CN214467934U). The utility model includes a cover, a sampling tube, a combustible gas concentration detector, an alarm, and an alarm bracket. The cover is made of thin-walled metal material and is installed at the flange connection of the natural gas pipeline by bolt connection, wrapping the flange connection to form a relatively closed cavity. One end of the sampling tube passes through the cover and is connected to the cavity, and the other end is connected to the air inlet of the combustible gas concentration detector. The output end of the combustible gas concentration detector is connected to the alarm, and the alarm is installed on the alarm bracket. According to this technical solution, when gas leaks, the gas concentration in the cover will increase rapidly. The combustible gas concentration detector on the top can quickly detect the gas leak and trigger the sound and light alarm, reminding the boiler operator that the pipeline is leaking.

For example, when installing the device, it is necessary to tighten multiple sets of bolts in sequence before the device can be installed. The installation efficiency is low and the device cannot be installed quickly. Therefore, we need to propose a gas pipeline detection alarm device. Utility Model Content
