The purpose of this utility model is the defect in order to solve in prior art existing for nitrogen storage tank, provides a kind of explosion-proof and nitrogen storage tank that flow is adjustable.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of nitrogen storage tank, comprise tank body, be provided with air outlet in the upper end of tank body, the lower end of tank body is provided with suction port, and the side of described tank body is provided with pressure safety mechanism, and described suction port place is provided with inlet control mechanism;
Described pressure safety mechanism comprises the relief valve be connected with described tank body, relief valve is provided with the pressure safety passage be communicated with described tank inner chamber, alumin(i)um zinc alloy post is inserted in pressure safety passage, the connecting port place of pressure safety passage and described tank inner chamber is provided with aluminium foil, the ends contact of aluminium foil and described alumin(i)um zinc alloy post;
Described inlet control mechanism comprises the air inlet rotary sleeve being arranged on described suction port place, the end of air inlet rotary sleeve is provided with inlet hole, the side face of air inlet rotary sleeve is provided with multiple transition air outlet hole be communicated with inlet hole, the mouth wall of described suction port is provided with multiple air outlet hole be communicated with tank inner chamber, the outer wall of air inlet rotary sleeve and the mouth wall close contact of described suction port.
Above-mentioned a kind of nitrogen storage tank, described air outlet place is provided with gas outlet valve.
Above-mentioned a kind of nitrogen storage tank, the inwall of described tank body is provided with thermal-protective coating.
Above-mentioned a kind of nitrogen storage tank, the transition air outlet hole quantity on described air inlet rotary sleeve side face is six.
The beneficial effects of the utility model are: the temperature in this nitrogen storage tank sharply rises when causing air pressure sharply to raise, nitrogen in tank body is by the aluminium foil bursting at pressure safety passage and tank inner chamber connecting port place, and alumin(i)um zinc alloy post is ejected in the pressure safety passage of relief valve, thus high pressure nitrogen is discharged in time from pressure safety passage, prevent the danger of bottle explosion, and be provided with inlet control mechanism at suction port place, inlet control mechanism comprises the air inlet rotary sleeve being arranged on suction port place, the end of air inlet rotary sleeve is provided with inlet hole, the side face of air inlet rotary sleeve is provided with multiple transition air outlet hole be communicated with inlet hole, the mouth wall of suction port is provided with multiple air outlet hole be communicated with tank inner chamber, the outer wall of air inlet rotary sleeve and the mouth wall close contact of suction port, when needing adjustment to enter the nitrogen flow of tank body, only need rotate air inlet rotary sleeve, thus control the size of transition air outlet hole and the relative connecting port of air outlet hole on suction port mouth wall on air inlet rotary sleeve side face, realize the object regulating charge flow rate, structure is simple, easy to use.
