Abstract
The utility model relates to a flow guide dynamic gas leakage testing and alarm device, which mainly comprises an outer shell, a gas sensor, a ventilation device, a gas inlet, a gas outlet and a filtering screen, wherein, both ends of the outer shell are provided with the gas inlet and the gas outlet; the gas sensor and the ventilation device are arranged in the outer shell; the filtering screen is covered on the gas inlet. The utility model can accurately send out alarm signals in time without errors.
Description
The utility model relates to a kind of gas leakage alarm device, particularly a kind of flow-guiding type detection of dynamic gas leakage alarm device belongs to Gas appliance class field.
Pick-up unit or warning device to gas leakage in the prior art all are to adopt static mode to detect the gas content that is leaked in its surrounding air, the design of this class mechanism and the detection effect and the sensitivity of leaking combustion gas, and the problem in serviceable life that detects the gas sensor of gas component, also there is obvious defects in varying degrees, as: in winter, the family door and window closes, indoor air flow property is bad, in case gas leakage, often in a room around the gas leakage source, leak gas content all to reach the warning punctuate of device, but alarm control unit is mobile bad because of room air, and can not report to the police in time and control.Moreover, this class pick-up unit or warning device all have some special requirements to the condition of installing, environment etc., as: can not install and use at the oil smoke place of flowing through, otherwise can influence the detection sensitivity of warning device and life problems of monitoring effect and gas sensor or the like.To such an extent as to still do not have a kind of simple in structurely at present, guarantee that device and gas sensor have the alarm control unit that high effect and high sensitivity are monitored.
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of flow-guiding type detection of dynamic gas leakage alarm device is provided.
The technical solution of the utility model is as follows: mainly comprise shell, gas sensor, air interchanger, air intake opening, gas outlet and filtering screen, the two ends of shell are provided with air intake opening and gas outlet, establish gas sensor and air interchanger in the shell, be covered with filtering screen on the air intake opening.When the combustion gas that contains in the air exceeds standard, the combustion gas that exceeds standard that shell is outer of the fan of air interchanger sucks by air intake opening, alerting signal can take place gas sensor reports to the police, because air intake opening is unimpeded to the gas outlet, alerting signal can in time take place the utility model like clockwork.
The utlity model has technical progress and good effect, can high effect, highly sensitive monitoring leaks combustion gas with detecting; On the other hand owing to be provided with filtering screen, gas sensor can be reported to the police exactly, reduce of the influence of spots such as dust, oil smoke, water vapor to gas sensor, make the work of whole warning device more reliable and stable, avoid the randomness warning, reported to the police late, controlled late, the utlity model has very strong practical value.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 the utility model structural representation
The structural representation of Fig. 2 filtering screen
As shown in Figure 1, the utility model mainly comprises shell (1), gas sensor (2), air interchanger (3), air intake opening (4), gas outlet (5), filtering screen (6), the two ends of shell (1) are provided with air intake opening (4) and gas outlet (5), establish gas sensor (2) and air interchanger (3) in the shell (1), be covered with filtering screen (6) on the air intake opening (4).
As shown in Figure 2, filtering screen (6) is formed by connecting by rack (9) by the filtering net film (8) of outer field dust-separation nethike embrane (7) and internal layer.When the combustion gas that contains in the air exceeds standard, the combustion gas that exceeds standard that shell (1) is outer of the fan of air interchanger (3) sucks by air intake opening (4), alerting signal can take place and report to the police in gas sensor (2), because air intake opening is unimpeded to the gas outlet, alerting signal can in time take place in the utility model like clockwork.
Claims (2)
1, a kind of flow-guiding type detection of dynamic gas leakage alarm device, mainly comprise shell (1), gas sensor (2), its feature mainly is: also comprise air interchanger (3), air intake opening (4) gas outlet (5), filtering screen (6), the two ends of shell (1) are provided with air intake opening (3) and gas outlet (4), establish gas sensor (2) and air interchanger (3) in the shell (1), be covered with filtering screen (6) on the air intake opening (4).
2, this flow-guiding type detection of dynamic gas leakage alarm device according to claim 1, its feature is that also filtering screen (6) is formed by connecting by rack (9) by the filtering net film (8) of outer field dust-separation nethike embrane (7) and internal layer.
