Embodiment Construction

[0024] Such as figure 1 Shown, this fire alarm detector detection method comprises the following steps:

[0025] a), dissolving the polymer compound methylphenyl silicone oil with the solvent odorless kerosene to form a solution; the mass ratio of the methylphenyl silicone oil to the odorless kerosene is 1:3;

[0026] b), the prepared solution of step a) is contained in a pressure vessel, and liquefied liquefied gas is added into the pressure vessel; the liquefied gas is a mixture of propane and butane, and the mass ratio of propane to butane is 3:7;

[0027] c) Using the liquefied gas to spray the polymer compound out to form tiny liquid droplets, which will affect the optical signal or electric field of the fire alarm detector, and the fire alarm detector will alarm.

[0028] Such as figure 1 As shown, the fire alarm detector detection device includes a pressure-resistant tank body 1, and the odorless kerosene solution dissolved with methylphenyl silicone oil, propane and...

Abstract

The invention discloses a detection method and a detection device for a fire alarm detector. The detection device comprises a pressureproof pot body which is provided with liquefied gas and a solvent in which a high-molecule compound is dissolved, wherein a gas atomization valve is arranged at the port opening on the top of the pressureproof pot body; the inlet of the gas atomization valve is connected with a suction pipe; and the suction pipe is inserted to the bottom in the pressureproof pot body. The high-molecule material dissolved in the liquefied gas is taken out by liquefied compressed gas; and under the action of the gas atomization valve, the high-molecule material is turned into tiny liquid drops; and the liquid drops influence an optical signal or an electric field of an alarm, so that alarming is realized. The device has the characteristic of high portability while realizing the detection function; and ignition combustion is not required on the spot, so that the test operation is relatively safe.

Description

technical field [0001] The invention relates to a detection method and device for a fire alarm detector. Background technique [0002] The fire alarm detector is a device that detects the smoke concentration and other information in the fire place and sends it to the alarm device. It is widely used in public places such as shopping malls, hotels, and hotels. Fire alarm detectors play a very important role in firefighting work. A fire alarm detector that works normally can give an alarm in time according to the change of smoke concentration in the early stage of a fire, so as to avoid the spread of fire and reduce the loss of people's lives and property. Therefore, it is necessary to conduct regular inspections of fire alarm detectors. [0003] At present, the fire alarm detectors commonly used in China are mainly divided into photoelectric and ion alarms. The alarm principle of the photoelectric alarm is that the fire smoke destroys the optical balance in the alarm, which r...
