Description
Technical field
The utility model relates to a kind of jockey that is used to connect combustion gas tool and source of the gas.
Background technology
No matter be average family or eating and drinking establishment at present, the jockey of widely used combustion gas tool and source of the gas mainly contains two kinds: a kind of is the sebific duct that is connected combustion gas tool and gas piping, another kind is the pressure-reducing valve of band sebific duct, be used to connect combustion gas tool and gas tank, sebific duct breaks when occurring, sticking oily after-combustion or come off when causing gas leakage, can't die automatically, easily cause security incident.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of high security jockey that is used for the combustion gas tool is provided, and can realize dying automatically when pipeline gas leakage occurring, thereby guarantee the safety that the combustion gas tool uses.
For achieving the above object, the high security jockey that is used for the combustion gas tool of the present utility model, comprise the valve that has air inlet pipe and escape pipe, the interior pipe that links to each other with escape pipe, it is characterized in that being provided with in the housing of described valve the spool that communicates and upwards be provided with air inlet pipe, the lever of one end belt spool cover is articulated in the housing, the below of the lever other end is provided with spring, the top is provided with air bag, on housing, pass through the spiral cover of screw thread mounting strap central shaft, the lower end of central shaft is positioned at housing and places the top of air bag, and air bag and lever or central shaft are connected; The outside at interior pipe also is surrounded by outer tube, and outer tube and interior pipe are the gap and are provided with, and are provided with enclosed construction between the two ends of outer tube and the interior pipe, and air bag also communicates with outer tube and housing aerating device outward respectively by tube connector;
Enclosed construction between the two ends of above-mentioned outer tube and the interior pipe can be the elasticity plug between the inner and outer pipe;
Enclosed construction between the two ends of above-mentioned outer tube and the interior pipe also can be the band that lies on the outer tube;
Above-mentioned aerating device can be a manually operated air compressor;
Above-mentioned aerating device also can be an air pump;
Using method of the present utility model is: air inlet pipe is linked to each other with the combustion gas tool with source of the gas respectively with interior pipe, by aerating device to inflating in air bag and the outer tube, make the air bag volumetric expansion and reach high pressure, rotate spiral cover, promote air bag, lever downwards successively by central shaft, the spool cover is risen, and combustion gas enters interior pipe by escape pipe, uses for the combustion gas tool; When breaking appears in outer tube, sticking oily after-combustion or come off when causing gas leakage, the gas leak in outer tube and the air bag, air bag shrinks, the spring terminal of lever rises under the effect of spring, and the spool cover of the other end descends, the sealing spool, realize dying automatically, thereby guarantee the safety that the combustion gas tool uses;
As further improvement of the utility model, on the housing of described valve, be provided with transparent form, be convenient to observe the position that the spool cover rises, handled easily;
In sum, the utility model can be realized dying automatically when pipeline gas leakage occurring, thereby guarantees the safety that the combustion gas tool uses, and is simultaneously easy to operate.
Description of drawings
