Description
Technical field
The present invention relates to the demonstration flame snuffer of a kind of fire-fighting fire extinguishing teaching demonstration and training usefulness.
Technical background
Universal knowledge on fire fighting more has significant role to personal safety not only to property safety.The fire drill action effect of community and school is not very big at present, and most of crowd, especially students in middle and primary schools are very few to flame snuffer understanding, and almost do not use flame snuffer.Therefore, the use crowd of expansion flame snuffer seems necessary.
Moreover, after the flame snuffer of manoeuvre training uses up, or scrap, otherwise can only by specialized department once more fill material and pressurization just can reuse, program is loaded down with trivial details, and cost is higher, and is obviously uneconomical.
Summary of the invention
Be to overcome high, the not re-usable shortcoming of cost of prior art, the invention provides a kind of simple in structure, the with low cost and demonstration flame snuffer that can be recycled.
The demonstration flame snuffer comprises airtight cylindrical shell, is positioned at the bung at cylindrical shell top, is positioned at the bottom of cylindrical shell bottom and is positioned at the inner nozzle of barrel, and be positioned at the outside outer nozzle of cylindrical shell; Described bung and bottom and cylindrical shell are tightly connected; Described bung is provided with and affixed fixed handle of bung and the flexible handle hinged with described fixed handle; Be provided with torsion spring between described fixed handle and the flexible handle, wear the latch that a prevention flexible handle rotates between described fixed handle and the flexible handle; Described inside and outside jet pipe is communicated with through the communicating valve in the bung, and described communicating valve and described flexible handle interlock are to be communicated with or to intercept interior outer nozzle;
It is characterized in that: the bottom indent of described cylindrical shell forms a charging aperture, described bottom is provided with rubber stopper adaptive with described charging aperture, that be tightly connected;
The wall of described charging aperture is provided with the switch of sealing charging aperture on one's body, and described switch comprises the magnet that is fixed in charging aperture wall body and is connected in the thin iron block of charging aperture wall body slidably; Described charging aperture is provided with a L type connecting rod, and described connecting rod is positioned at cylindrical shell, and the corner of described connecting rod and charging aperture wall body are hinged, and a ball float, lower end abutment are fixed in described thin iron block in the upper end of described connecting rod;
Described cylindrical shell is provided with valve inside and barometer.
Further, described communicating valve comprise with the bung internal partition on the adaptive and cover plate that is tightly connected of intercommunicating pore, with the connecting link that is connected described cover plate and flexible handle, described connecting link and described cover plate and flexible handle are and are articulated and connected.
Further; Described cylindrical shell is provided with safety valve, and described safety valve comprises the housing affixed with described cylindrical shell, air pressure mouth that the gas in the permission cylindrical shell passes through and the valve plug adaptive with the air pressure mouth; Be provided with spring between described valve plug and the housing, vent port is arranged outward on the described housing.
Further, described valve plug is provided with valve cock stem, and described valve cock stem is arranged in housing, on described spring suit and the valve plug; Described valve plug and air pressure mouth all are wedge shape.
Further; Described barometer comprises the shell that is fixed on the cylindrical shell; Described outer casing bottom is provided with the extension that is communicated with barrel, is provided with the rubber tube that is communicated with barrel in the described extension, and described rubber tube pushing tow one is adaptive with extension, along the push pedal of extension slip; Described push pedal is through linkage assembly and pointer interlock; Described linkage assembly comprises first sub bar and second sub bar that is articulated and connected, and described first sub bar and described push pedal are hinged, and described second sub bar and pointer are hinged.
Further, an end that exposes to charging aperture of described thin iron block is provided with shifting block, described thin iron block with described connecting rod against an end be provided with pulley.
Further, the wall of described charging aperture is provided with on one's body and allows material to get into the through hole in the cylindrical shell.
Further, described cylindrical shell is equipped with inflator outward.
The present invention is inverted the cylindrical shell of demonstration flame snuffer before use, the said bottom of outwarding winding, and unplug said rubber lid; Stir shifting block simultaneously to push thin iron block open, water filling in charging aperture is when liquid contacts with ball float; Ball float rises and drives L type connecting rod in buoyancy and rotates, and the L type connecting rod other end forces thin iron block to slide to magnet through pulley, when resistance that magnet receives greater than thin iron block the gravitation of thin iron block; Thin iron block is instantaneous docks with magnet, and charging aperture is closed, and water filling stops.
During inflation, the cylindrical shell of demonstration flame snuffer is just put, in cylindrical shell, inflated through valve inside with inflator, elastic rubber tube drives pointer because of the difference degrees of expansion of pressure in the tube is different through linkage assembly, and pointer deflects to realize the pressure indicative function; When pressure is excessive in the tube, air will be washed the valve plug of safety valve open, overflow from the vent port of safety valve, realize pressure release.
During use, pull out the latch between fixed handle and the flexible handle, press down flexible handle, water from the outer nozzle ejection, is realized the demonstration effect at last through said inner nozzle and bung.
Because of working environment is a liquid, magnet and thin iron block surface all varnish with lacquer.
Advantage of the present invention is:
