Description
The utility model relates to the liquefied petroleum gas is the combustion apparatus of fuel, a kind of specifically little volume liquefied petroleum gas steel cylinder and special stove and aerating device.
The steel cylinder capacity of existing liquefied petroleum gas stove generally more than 10 kilograms, is added the weight of steel cylinder self, thereby seems very heavy.And the volume of kitchen range, weight are also bigger, generally fixedly lay, and are connected with steel cylinder by flexible pipe.And kitchen range also need special support, therefore are difficult to move freely, and more can't carry.
The employed steel cylinder of existing liquefied petroleum gas stove generally is old for new service, and the inflation of steel cylinder all is to carry out with special-purpose aerating device in liquefied petroleum-gas station, does not still have a kind of aerating device that is suitable for family expenses.
The purpose of this utility model at first is the liquefied petroleum gas steel cylinder that proposes a kind of little volume; Next proposes a kind of supporting with it kitchen range, and when both were used, available steel cylinder replaced support, and it is integrated that steel cylinder and kitchen range are realized, thereby be convenient to carry; The 3rd, be to propose a kind of aerating device that is applicable to above-mentioned little volume liquefied petroleum gas steel cylinder.
Little volume liquefied petroleum gas steel cylinder described in the utility model comprises bottle and advances (going out) gas valve assembly two large divisions.(going out) the gas valve assembly that advances of steel cylinder is made up of valve base and valve, back-moving spring, plug screw, and valve is fixed in the valve base by plug screw, and its underpart is with back-moving spring, and plug screw is stretched out on top, and valve base lower end one side has an air admission hole.
Kitchen range described in the utility model comprise support, pin plug switch and the air inlet valve body, kitchen range dish and the burner that connect in turn from bottom to top, and support is installed on the kitchen range dish, and pin plug switch is positioned at a side of intake valve body.The air inlet valve body lower end forms dismountable fixedlying connected with the valve base that advances (going out) gas valve assembly of steel cylinder.
Aerating device described in the utility model comprises the inlet suction port of the air outlet adapter, pressure pipe, charging valve, pipe joint and the band handwheel that connect in turn.
The utility model compact conformation, installation, easy to carry is widely used in unregulated power, does not have place such as desert, deserted mountain, wilderness and the pleasure trip on foot tourism of the burning energy, for people provide combustion tool.Wherein, steel cylinder also can with other liquefied petroleum gas combustion equipment such as supporting uses such as liquefied petroleum gas lamp and liquefied petroleum gas warmer.
The utility model is described in further detail below in conjunction with drawings and Examples.
Figure one is the structural representation of little volume liquefied petroleum gas stove and kitchen range (when being used).
Figure two is the schematic diagram of aerating device.
Referring to figure one, little volume liquefied petroleum gas steel cylinder described in the utility model by bottle 1, advance (going out) gas valve assembly and air bleed valve assembly 17 and constitute.In order to reduce the center of gravity of steel cylinder, strengthen the stability of kitchen range, the bottle 1 of steel cylinder is designed to ellipse.Advance (going out) gas valve assembly and be positioned at bottle 1 top, form by valve base 2, valve 4, back-moving spring 3, plug screw 16 and O-ring seals 18 and 19.Valve base 2 is welded on the bottle 1, and its right side, lower end also has into (going out) pore.Valve 4 is fixed in the valve base 2 by plug screw 16, and its underpart is with back-moving spring 3, and plug screw 16 is stretched out on top.Sealing ring 18 is contained between plug screw 16 and the valve base 2, and 19 of sealing rings are contained between plug screw 16 and the valve 4.
Kitchen range described in the utility model are made of support 7, pin plug switch 13, air inlet valve body 8, kitchen range dish 6, burner 12 and planar seal ring 14 and O RunddichtringO 15.Pin plug switch 13 is positioned at the right side of air inlet valve body 8, and air inlet valve body 8, kitchen range dish 6 and burner 12 are fixed into one by thread connection.Air inlet valve body 8 inner chambers are blast tube b, and there is with steel cylinder the screw thread that the valve base 2 of (going out) gas valve assembly matches its lower end, and whole kitchen range combine as a whole by air inlet valve body 8 and steel cylinder.O-ring seals 15 and planar seal ring 14 are contained between air inlet valve body 8 and the valve base 2, carry out twice and obturage, to guarantee the sealing of the two connection.In order to filter the impurity in the combustion gas and combustion gas to be atomized, the nozzle 10 of a band filter screen also is equipped with in air inlet valve body 8 upper ends.
Referring to figure two, aerating device described in the utility model is connected in turn by the inlet suction port 23 of air outlet adapter 20, pressure pipe 21, transit joint 27, inflation valve 22, pipe joint 26, band handwheel and forms.Pipe joint 26 and inflation valve 22 end that joins is Taper Pipe shape.The band handwheel inlet suction port 23 be enclosed within outside the pipe joint 26, on the screw thread that matches with the source of the gas steel cylinder is arranged.For the impurity in the filtered fluid gasification, a filter screen 25 is housed in the pipe joint 26.For the sealing that guarantees to connect with the source of the gas steel cylinder, pipe joint 26 right-hand member ends also have an arc sealing ring 24.Air outlet adapter 20 has the screw thread that matches with the valve base 2 that advances (going out) gas valve assembly of above-mentioned little volume liquefied petroleum gas steel cylinder.In addition, in the connection place of air outlet adapter 2O and pressure pipe 21 and excessive joint 27 and pressure pipe 21 clip 28 is arranged all, with the sealing that guarantees to connect.
During use, two end connectors of aerating device are connected with steel cylinder described in the utility model and source of the gas steel cylinder respectively and tighten.Open the switch of source of the gas steel cylinder and the inflation valve 22 of aerating device gradually, the liquefied gas of source of the gas steel cylinder is slowly poured in the steel cylinder.After a few minutes, suitably open the air bleed valve 17 on the steel cylinder, observe and adjust the inflating condition in the steel cylinder.After inflation finishes, close the inflation valve 22 of source of the gas steel cylinder switch and aerating device, unclamp the inlet, outlet joint of aerating device.At this moment, because the elastic force of back-moving spring 3, with upwards ejection and compress O RunddichtringO 19 of valve 4, steel cylinder is promptly from movable sealing.
Then, the air inlet valve body 8 of kitchen range is screwed in the valve base 2 of steel cylinders, under the effect of air inlet valve body 8, the elastic force that valve 4 overcomes back-moving spring 3 moves down, and gas circuit a, b are communicated.Open valve 4 again, liquefied gas can be along gas circuit a, b from nozzle 10 enters gas circuit c (being burner 12 inner chambers).Simultaneously, because the effect of negative pressure, a large amount of air enter in the burner 12 from air admission hole 9, form air mixture.Air mixture because the base plate of combustion chamber becomes to cross shape wave, makes liquefied gas and air further mix after entering in the combustion chamber of burner 12.Like this, just can fully guarantee the efficiency of combustion of liquefied gas.
