Background technique
In recent years; Enhancing along with the mine safety prevention awareness; The beam tube monitoring system obtains on the circle, ore deposit promoting, using gradually; Promptly adopt polythene beam tube that the sample gas of each Check point in the mine is aggregated into sensing chamber,, realize early prediction the mine natural fire through concentration ratio analysis to each composition gas in the sample gas.In the practical application,, need usually regularly each the road beam tube in the mine to be detected, to check whether there is the gas leakage point for guaranteeing system analysis result's accuracy.
At present, each mine adopts manual type to come the integrity of each road beam tube is detected usually, and manual work is checked along the beam tube pointwise; Whether breakage judges whether beam tube leaks gas through observing the beam tube surface, very time-consuming, the effort of this kind method, and sense cycle is long; Particularly the beam tube jacket surface is intact, and inner core pipe is damaged, and just detects not come out during gas leakage; Cause the gas at gas leakage point place to be sneaked in the core pipe; Influence the analysis of trend result of Check point place gas content, can not make the beam tube monitoring system bring into play its forewarning function normally, the safety of mine is on the hazard.
Summary of the invention
The utility model technical problem to be solved provides a kind of beam tube leak detector, can the accurate detection mine in beam tube whether intact.
For solving the problems of the technologies described above; The technological scheme of the utility model is: design a kind of beam tube leak detector; It is characterized in that: said beam tube leak detector comprises air compressor and high pressure gas holder, and air compressor is connected with high pressure gas holder, and reduction valve and pressure gauge are set on the delivery outlet of high pressure gas holder.
Preferably, the delivery outlet of high pressure gas holder is communicated with gas distributor, on each delivery outlet of gas distributor pressure gauge and solenoid valve is set respectively, and each solenoid valve passes through switch connection working power separately respectively.
Preferably, on each delivery outlet of gas distributor power supply indicator is set respectively, power supply indicator is connected to the solenoid valve two ends of place delivery outlet.
Preferably, working power is the DC electrical source of 24V.
The beneficial effect of the utility model is:
1, is connected with high pressure gas holder owing to air compressor; Reduction valve and pressure gauge are set on the delivery outlet of high pressure gas holder, can make the delivery outlet of high pressure gas holder connect an end of beam tube middle core pipe to be checked, and the other end of core pipe is stopped up; Calm the anger in the core pipe through high pressure gas holder; Observe manometric numerical value change situation and can judge this core pipe and whether leak gas, then to the core pipe of gas leakage by its concrete gas leakage point of manual work investigation, thereby improved speed and accuracy rate that beam tube detects; Reduction valve has then guaranteed to give beam tube institute applied pressure not exceed standard, and makes beam tube avoid damaging.
2, because the delivery outlet of high pressure gas holder connects gas distributor; On each delivery outlet of gas distributor pressure gauge and solenoid valve are set respectively; Each solenoid valve passes through switch connection working power separately respectively; Can make each delivery outlet of gas distributor connect different core pipes respectively, detect many core pipes simultaneously, further improve the detection rates of beam tube.
3, on each delivery outlet of gas distributor power supply indicator is set respectively, power supply indicator is connected to the solenoid valve two ends of place delivery outlet, can show the working condition of each delivery outlet of gas distributor intuitively, and the staff is come into plain view.
4, because the nominal operation power supply of multiple electronic parts and components is the DC electrical source of 24V, select for use the DC electrical source of 24V to be convenient to choosing, purchasing of electronic parts and components.
