Detailed Description
Referring to fig. 1-4, the utility model provides a gas meter with alarm function, which comprises a meter shell 1 and a detecting tube 2; wherein:
the instrument shell 1 is provided with a display meter 12, a transmission pipe 3 is arranged in the instrument shell 1, the transmission pipe 3 is in a spiral shape, and an air inlet pipe 4 communicated with the transmission pipe 3 is arranged at the bottom end position outside the instrument shell 1.
In the embodiment, a piston is installed in an inner sleeve 6 in a sliding and sealing manner and is connected with a pressure alarm 9 through a spring rod 7, in the embodiment, a gas meter is movably installed on an external pipeline, a gas inlet pipe 4 transmits gas in the external pipeline to a transmission pipe 3, the transmission pipe 3 transmits the gas into a guide pipe 5, the guide pipe 5 transmits the gas to the inner sleeve 6, a gas detector detects the gas concentration in the inner sleeve 6 in real time, and a display meter 12 displays the gas concentration in real time; under the impact of gas, the piston can be pushed, the piston moves to extrude the spring rod 8, and the spring rod 8 transmits acting force to the pressure alarm 9; when gas transmission is too big, the effort to spring beam 8 is big more, when exceeding the pressure threshold value that pressure alarm 9 presetted when great pressure appears, can trigger pressure alarm 9 and report to the police, reduces the damage to gas instrument, improves safety awareness.
In this embodiment, as shown in fig. 4, a plurality of valve plates 10 are movably mounted in the guide pipe 5 at intervals along the axial direction thereof. The valve plate 10 can conduct the gas transmitted in the guide pipe 5, and the problem that the guide pipe 5 leaks due to the fact that the gas transmission speed is too high is avoided.
