Description

Combustible gas alarm device Technical Field The utility model relates to the technical field of flammable gas detection, in particular to a flammable gas alarm device. Background The combustible gas alarm device is a safety device for detecting the concentration of the combustible gas in the environment and sending out an alarm when a preset threshold value is reached so as to remind personnel to take measures to prevent fire or explosion accidents. The device is widely applied to industrial plants, commercial buildings, houses and other places, and has important significance for guaranteeing the life and property safety. The existing combustible gas alarm device enables air to flow to the gas detector through the gas collecting hood, so that the gas detector detects the concentration of combustible gas in the air, when the concentration is too high, an alarm is sent out to remind, but because the gas collecting hood is always kept in an open state, the gas continuously flows through the gas detector to accelerate the aging process, and continuous sampling can lead to failure of the gas detector, and the reliability of a measurement result is affected. Therefore, a combustible gas alarm device which can enable the gas detector to intermittently sample and detect, prolong the service life of the gas detector and improve the detection precision is developed. Disclosure of utility model In order to overcome the defects that the aging process of the gas detector can be accelerated when the gas continuously flows through the gas detector and the gas detector is invalid due to continuous sampling and the reliability of a measurement result is influenced in the conventional combustible gas alarm device, the utility model provides the combustible gas alarm device which can intermittently sample and detect the gas detector, prolong the service life of the gas detector and improve the detection precision.
