Problems solved by technology

Because standard gas cylinders need to be moved up and down frequently, there are problems of high labor intensity, high risk, and low efficiency of verification work
Most of the more advanced verification devices on the market are too expensive. The most important thing is that for portable gas alarms, when there is no electrical signal output for collection, the timing of stable value collection after the instrument is connected to standard gas cannot be accurately judged.

Embodiment Construction

[0040] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments are listed below and shown in the accompanying drawings in detail as follows.

[0041] Such as figure 1 as shown, figure 1 It is a schematic diagram of the verification device used in most laboratories currently engaged in the verification of gas alarms. The gas alarm verification device includes a standard gas cylinder 1, a pressure reducing valve 2, a gas circuit module 3, and a gas alarm 4. During the verification, the standard gas in the standard gas cylinder 1 is decompressed by the pressure reducing valve 2, then output through the gas delivery pipeline 3, and sent to the gas alarm 4 to be tested for verification.

[0042] Figure 8 It is a structural diagram of a gas alarm verification device, which includes a gas alarm verification module 71 , a gas circuit module 3 , a portable ventilation box 72 and a diffusion cover co...

Abstract

The invention provides a gas alarm calibrating device. The gas alarm calibrating device comprises a gas alarm calibrating module, a gas path module, a portable ventilation box and a diffusion cover connector, the diffusion cover connector is located in the portable ventilation box and used for clamping a gas alarm to be calibrated, and the gas alarm calibrating module is connected to the gas alarmto be calibrated through the gas path module so as to calibrate the gas alarm. According to the gas alarm calibrating device, the calibrating efficiency is improved by three times, the labor intensity of calibrating personnel is greatly reduced, and the risk of occupational diseases is reduced. Therefore, the gas alarm calibration process becomes convenient, quick, safe and efficient, and a veryideal use effect is achieved.

Description

technical field [0001] The invention relates to the technical field of flammable and toxic and harmful gas alarm verification, in particular to a gas alarm verification device. Background technique [0002] In recent years, safety accidents caused by flammable and toxic and harmful gases have made petrochemical companies continue to increase their safety protection for oil and gas development, storage, and processing. As important safety protection equipment, flammable and toxic and harmful gas alarms are being purchased and used. increased substantially year by year. At present, when the gas alarm is verified in the laboratory, most of them are still using the standard gas supplied outside the standard gas cylinder in the fume hood for verification. Because standard gas cylinders need to be moved up and down frequently, there are problems of high labor intensity, high risk, and low efficiency of verification work. Most of the more advanced verification devices on the mark...
