Description

The gasification safety device of liquid fuel

The utility model relates to a kind of gasification installation of liquid fuel, be meant a kind of common on the market gas cylinder structure at present that is directly applied for especially, and need not specially designed tube structure or repacking structure, with the device of the effect such as safe in utilization that reaches liquid fuel gasification.

Employed fuel on the present general industry, generally can be divided into liquid fuel and fuel gas, wherein liquid fuel mainly is to be base stock with flammable liquids such as gasoline or alcohol, fuel gas then is to be base stock with imflammable gas such as natural gases, and in order to increase the gas volume that container can hold, general fuel gas all passes through HIGH PRESSURE TREATMENT, make it to be stored in the container of similar steel cylinder with liquid state, when using, open a control valve again, make this fuel outflow and evaporate into gas for use.Yet, the steel cylinder container of the ccontaining fuel gas of above-mentioned tradition, whether no matter it use, and all is in high pressure conditions, thus the user take carve careful, especially when in stop using, it is deposited and also needs very careful (during nobody nurse of side), otherwise, effect of any external force improperly or variation of temperature, all easily produce the danger of blast, cause life, property to threaten greatly.

Because said circumstances, industry has with mixed liquor, and filling is injected pressure-air by a charger in container, then can and discharge fuel gas for use via the evaporation mixing; This kind mixed liquor form, though it can produce high pressure in container when using (giving vent to anger), but the steel cylinder container identical operations mode with at present general fuel gas that only notes gets final product, and next in the state of stopping using (stopping to give vent to anger) be the liquid state that is low pressure, can be convenient to receive and keep and be difficult for to produce the danger of blast.

And relevant for the structure of container of ccontaining aforementioned mixed liquor, disclosed at present structure of container is of a great variety, but it all must be handled with special processing unavoidably (as boring, welding ... Deng), can meet the demand on its general safety and the function, thus, make whole exploitation and manufacturing cost be difficult to effective reduction, and traditional mixed solution container structure is for preventing that oil gas from returning the also obvious deficiency of contrary safety devices, has oil gas and return contrary danger situation generation under some specific situation.

Main purpose of the present utility model is to provide a kind of gasification safety device of liquid fuel, it can be directly applied for common on the market gas cylinder (steel cylinder) structure at present, and need not specially designed structure of container or repacking structure, can effectively reduce the container production cost and enlarge the scope of application of container.

According to the gasification safety device of this kind of the utility model liquid fuel, it is provided with devices such as non-return valve on the pipeline of inflation, can effectively avoid oil gas to return contrary danger situation and produce, and promotes the security on whole the use, and this is another purpose of the utility model.

The purpose of this utility model is to realize like this, it is by body, leaving air control valve, propellant bottle and inflating pump are formed, body is to be hollow tube body, its top, the bottom is respectively equipped with screw and external screw thread connects leaving air control valve and propellant bottle, the leaving air control valve top side is provided with knob, body periphery wall is provided with and the gas tube that is communicated with outward, connection duct and outward extending fuel injected pipe, form an inflation inlet on gas tube one end and the body wall, the other end is provided with non-return valve, gas tube all is vertical bending with connection duct and extends downwards, the connection duct bottom side is provided with the liquid level perceptron, the lead that the liquid level perceptron is connected is stretched by body perimeter wall facing epitaxy and is connected a display unit, and gas tube is provided with pipeline and connects inflating pump.

As for detailed construction of the present utility model, application principle, effect and effect, then the explanation of doing with reference to following accompanying drawing can be arrived the understanding of safety:

Fig. 1 is an entire combination generalized section of the present utility model;

Fig. 2 is the structure decomposition map of the utility model body and relevant apparatus;

Fig. 3 is the constitutional diagram of the utility model body and its relevant apparatus.

Fig. 1 is an entire combination generalized section of the present utility model, by it with reference to Fig. 2, Fig. 3, can clearly find out, the utility model mainly comprises: body 1, leaving air control valve 2, propellant bottle 3 and inflating pump 4 etc. are partly, wherein body 1 is one to be hollow tube body, its top, the end, be arranged with a screw 11, external screw thread 15, then be provided with on the body 1 periphery wall and the gas tube 12 that is communicated with outward, connection duct 13, a pressure sensor 16 and an outward extending fuel injected pipe 14, this gas tube 12, connection duct 13 all is vertical bending and extends downwards, gas tube 12 1 ends form an inflation inlet 121 in body 1 wall, end and appropriate location then are provided with more than one non-return valve 122 in addition, and the bottom of connection duct 13 is provided with a liquid level perceptron 131, start additional liquid fuel with the detecting liquid level, and the suitable fuel supplement time of gauge tap, 132 in the lead that this liquid level perceptron 131 is connected can be stretched by body 1 perimeter wall facing epitaxy, the outer end of fuel injected pipe 14 then can cover by a lid 141, the top side of leaving air control valve 2 is provided with a knob 22, can control wherein unlatching and closed state that section sets out gas port 21, the bottom of leaving air control valve 2 then is provided with external screw thread 23, can be screwed together in the screw 11 of body 1 top side, propellant bottle 3 top sides are provided with a screw 31, can screw togather fixing for the external screw thread 15 of aforementioned body 1, and inflating pump 4, then be connected with the inflation inlet 121 of body 1 through a component switch valve 41, and it can be fitted needs and in inflating pump 4 and 41 of component switch valves a non-return valve 42 is set by pipeline.After the combination, gas tube 12, connection duct 13 can stretch into appropriate depth in the propellant bottle 3 via screw 31, can pour an amount of liquid state combustion amount 5 into to propellant bottle 3 by fuel injected pipe 14, inject pressure-air by inflating pump 4 to propellant bottle 3 via gas tube 12, after making the evaporation body of the pressure-air of injection and liquid fuel 5 be mixed into flammable oil gas, can discharge by gas outlet 21 through the control of knob 22, for use, 122,42 of this non-return valves can prevent that this liquid fuel 5 (or oil gas) is contrary to inflating pump 4 by gas tube 12 times, avoid producing explosion danger; But pressure sensor 16 is the air pressure in the perception propellant bottle 3 then, action with control inflating pump 4, make and be able to the air pressure of giving vent to anger and avoiding keeping between Keep Clear-High Voltage a proper range in the propellant bottle 3 in smooth and easy, 131 of liquid level perceptrons can be delivered to sensing signal one display unit (not drawing) via lead 132 again, replenish when liquid fuel 5 is not enough or the structure of switch with the prompting user.

From the above mentioned as can be known, the gasification safety device of liquid fuel of the present utility model has the production of reduction really Cost, the advantage that enlarges the scope of application and promote security protection can be improved the corresponding shortcoming of common technique.
