Technical field

The utility model relates to a kind of integrated gapless oxygen to light up, and belong to mine safety protective device field.

Background technique

The life oxygen starter (referred to as " oxygen candle ") used in existing potassium superoxide self-rescuer, usually by irony cold plate Material is drawn into bowl-shape, then welds an end cap at the rim of a bowl again and is made, and this old money oxygen pressure-resistant coefficient of lighting up is low；And And when being inflated into tank, influenced by high-pressure aerated gas, tabletting is easy to be blown flat, this results in not continuing to be filled with oxygen Gas；In addition, to protrude into tank interior volume larger for valve seat, a large amount of gas storage spaces are occupied.Above situation causes oxygen in tank body and stores Storage is lower, so as to cause using the time short, is unable to satisfy the requirement of some special circumstances.

Utility model content

According to the above-mentioned deficiencies in the prior art, technical problem to be solved by the utility model is: providing a kind of oxygen storage The higher integrated gapless oxygen candle of storage.

One gapless oxygen candle described in the utility model, including tank body, tank body are integrated drawing and forming structure, tank body Valve seat is connected at port, the top of valve seat is equipped with upper screwed hole, and the bottom of valve seat is equipped with lower threaded hole, upper screwed hole and lower spiral shell The first venthole is connected between pit, upper screwed hole internal screw thread is connected with the spool of T-type, is fixed with and opens on the transverse arm of spool Dynamic valve, the upper end of the longitudinal wall of spool are equipped with the first threaded joints to match with upper screwed hole, under the longitudinal wall of spool Outer diameter is held to be less than the internal diameter of upper screwed hole, the bottom of spool is equipped with top, is threaded with screw plug, spiral shell at the port of lower threaded hole Stifled upper and lower ends are through there is the second venthole, and the top of screw plug is fixed with inverted T shaped sealing-plug by holding spring, sealing-plug Longitudinal wall protrude into the first venthole and with top up and down it is corresponding, gasket, the side wall of valve seat are also cased in the longitudinal wall of sealing-plug On be also connected with the gas-guide tube being connected to upper screwed hole.

The side wall of above-mentioned valve seat is equipped with side threaded hole, and one end of gas-guide tube is successively arranged limiting section and the from outside to inside Two threaded joints, the second threaded joints match with side threaded hole, and the longitudinal wall of spool is equipped with corresponding with limiting section Limiting slot, can prevent in emergency circumstances, user invert and so that spool is fallen off, rise safety protection function.

Above-mentioned top is sphere curved surface, is point contact between top and sealing-plug, and frictional force is small.

To be threadedly coupled between above-mentioned tank body and valve seat, it is easily installed, dismantles.

Above-mentioned tank body is stainless steel material, corrosion-resistant, resistance to oxidation.

Possessed beneficial effect is the utility model compared with prior art:

One gapless oxygen candle described in the utility model, tank body are airtight without welding using integrated gapless structure Property more preferable, more difficult gas leakage, voltage endurance capability is stronger, also, by way of by the stretched tank mouth of tank body, make valve seat occupy storage Headroom is smaller, thus can save oxygen amount it is higher, meet requirement significantly.
