Embodiment Construction

[0025] see figure 1 , which is a detection device for the tightness of an alcohol lamp in the present invention. As shown in the figure: it consists of an inflation needle 1, a pressure display 2, a valve 3, an air compressor 4 and a tube body 5; the inflation needle 1 and the air compressor 4 are respectively connected to both ends of the tube body 5, and the middle A pressure indicator 2 and a valve 3 are respectively installed on the pipe body 5 .

[0026] The detection steps are as follows:

[0027] Step 1: Insert the wick into the opening of the lamp pot of the alcohol lamp;

[0028] Step 2: Use the inflatable needle of the detection device to pierce the wick so that the needle enters the lamp pot;

[0029] Step 3: Open the valve of the inflatable device in the detection device, and fill the lamp pot with positive air pressure;

[0030] Step 4: Close the inflation valve and observe the attenuation of the air pressure after keeping it for a period of time; if the atten...

Abstract

The invention relates to a detection method for the sealing performance of alcohol burners and a device therefore. The detection method comprises: mounting a wick into the mouth of the pot of an alcohol burner; penetrating the wick via an inflation needle of the detection device to enter into the pot; opening the valve of an inflator of the detection device to charge positive pressure into the pot; closing the inflation valve, holding for some time, observing the attenuation amount of the pressure; when the attenuation amount is lower than preset value, considering that the product has qualified sealing performance professedly, or else, the product has unqualified sealing performance professedly. The invention mainly resolves the technical problems of the prior detection method which need to ignite product and need visual inspection. The invention has scientific detection and improved efficiency.

Description

technical field [0001] The invention relates to the technical field of detecting the airtightness of containers, in particular to a method and a device for detecting the airtightness of an alcohol lamp. Background technique [0002] Alcohol lamps are alcohol-fueled heating tools that are usually used in laboratories. The heating temperature of the alcohol lamp is 400-500°C, which is suitable for experiments where the temperature does not need to be too high, especially when there is no gas equipment. The alcohol lamp is usually composed of three parts: the lamp cap, the wick and the lamp pot filled with alcohol. The wick is passed through the small hole provided at the mouth of the lamp pot. Specifically, the wick is usually twisted together with multiple strands of cotton yarn and inserted into the wick porcelain sleeve. When in use, light the wick and get final product. After use, cover the lamp cap on the mouth of the lamp pot to extinguish the alcohol lamp. [0003] ...
