Problems solved by technology

[0004] Although the circuit system of the existing combustible gas alarm itself is used to monitor false alarms and zero drift, it cannot check whether it can alarm in a normal alarm environment
Therefore, when the combustible gas alarm is tested, the combustible gas alarm needs to be removed from the gas system and tested in a laboratory, which makes the operation of the detection method more cumbersome and rarely Real-time or regular detection of the combustible gas alarm

Embodiment 1

[0041] see figure 1 , the present embodiment 1 provides a spot checker 10, the spot checker 10 includes a jar 12 and a spot check agent 14 and a sponge 16 sealed in the jar 12, wherein the sponge 16 is stacked on the spot check agent 14 for the upper gate. The sealing cap of the wide-mouth bottle 12 is fixed on the mouth of the wide-mouth bottle 12 by means of a screw.

[0042] The preparation method of described inspection agent 14 is: take by weighing 3 grams of hard acid, 1 gram of paraffin, several grains of zeolite, pour into three-necked beakers, inject 20 milliliters of cyclohexane, 10 milliliters of normal hexane, and 3 milliliters of water into it, Use a water bath to heat, the temperature is controlled at about 65°C, keep warm until completely dissolved; measure 2 ml of water into the beaker, add 1 g of NaOH, shake well until completely dissolved, then measure 10 ml of cyclohexane into the beaker, mix well Then slowly pour it into a three-neck flask. Heating for 5...

Embodiment 2

[0046] Weigh 3 grams of hard acid and several grains of zeolite, and pour them into three-necked beakers. Measure 30 milliliters of ethanol, 10 milliliters of n-hexane, 10 milliliters of n-octane, and inject 3 milliliters of water into it, heat it in a water bath, control the temperature at about 65°C, and keep it warm until completely dissolved; measure 2 milliliters of water into the beaker, add 1 gram of NaOH, shake until completely dissolved, then measure 10 ml of ethanol and pour it into a beaker, mix well and slowly pour it into a three-neck flask. Heated for 4 minutes, stopped heating and poured into a wide-mouthed bottle to obtain a spot check agent, and simultaneously obtained a spot check device. The components of the inspection agent are: 5.8% sodium stearate, 58.0% ethanol, 14.5% n-hexane, 14.5% n-octane and 7.2% water.

[0047] The structure of the spot checker using the above-mentioned spot check agent is the same as that of the spot checker 10 provided in Embod...

Embodiment 3

[0050] Weigh 3 grams of hard acid and several grains of zeolite, and pour them into three-necked beakers. Measure 20 milliliters of ethanol, 20 milliliters of n-hexane, and 5 milliliters of water into it, heat it in a water bath, control the temperature at about 65°C, and keep it warm until completely dissolved; measure 3 milliliters of water into a beaker, add 1 gram of NaOH, and shake well until All dissolved, then measure 10 ml of ethanol and pour it into a beaker, mix well and slowly pour it into a three-neck flask. Heated for 6 minutes, stopped heating and poured into the mold to obtain the spot check agent. The components of the inspection agent are: 6.5% sodium stearate, 49.1% ethanol, 32.8% n-hexane and 11.5% water.

[0051] The structure of the spot checker using the above-mentioned spot check agent is the same as that of the spot checker 10 provided in Embodiment 1. Place the spot checker near the air inlet of the online GDII household combustible gas alarm, check ...

Abstract

The invention provides a point inspection agent which is used for carrying out point inspection on a combustible gas alarm. The point inspection agent comprises the following components in percentage by mass: 2.5%-8% of a coagulator, 76%-93% of an organic solvent and 5%-16% of water. The organic solvent is uniformly mixed with the water and wrapped in the coagulator; the organic solvent comprises normal hexane and / or diethyl ether; the coagulator comprises sodium stearate. The invention also provides a point inspection machine using the point inspection agent and a preparation method of the point inspection agent. A method for using the point inspection agent and the point inspection machine is simple; the point inspection agent and the point inspection machine can be used for directly inspecting without changing the state, the position and the like of the combustible gas alarm and have the characteristics of convenience in operation, sensitiveness in response, quickness in detection and the like; the point inspection agent and the point inspection machine are low in cost, relatively small in pollution and capable of carrying out point inspection on the alarm in real time, and the raw materials are easily available. The preparation method of the point inspection agent is relatively simple.

Description

technical field [0001] The invention relates to a detection device of a combustible gas alarm and a preparation method thereof, in particular to an inspection agent for detecting a household combustible gas alarm, an inspection device and a manufacturing method of the inspection agent. Background technique [0002] Natural gas is used in family life. Although it provides convenience for family life and contributes to environmental protection, natural gas is a flammable and explosive gas. If the gas leaks, it is more likely to cause an explosion accident, resulting in property loss and personal injury. Therefore, it is necessary to monitor natural gas to ensure the safety of personnel and property. [0003] Although the existing combustible gas alarm can monitor whether the gas exceeds the standard in real time, which provides a guarantee for the safety of personnel and property, gas leakage is not a frequent occurrence after all. Therefore, the combustible gas alarm may not...
