Confirm that after deliberation the raffinate after the liquid gas burning is to deposit admittedly in the liquid gas and have one of energy component of higher calorific value very, accounts for the 3%-15% of liquid gas gross weight.Owing to can't being gasificated into gas derivation steel cylinder under normal temperature condition, these components become raffinate.Problem hereto, once the someone studied and utilized the injection principle of air-flow, had designed the flow deviding type economizer.But too small when the injection air-flow, this airflow injection just can't be realized when the liquid phase liquid level was hanged down than low and ambient air temperature, so up to the present, the raffinate problem in the liquified petroleum gas cylinder does not still obtain substantial solution.

The model utility content

Technical problem to be solved in the utility model provides a kind of bottled gas liquid gas and joins the phase economizer, this apparatus structure is simple, cost is lower, sturdy and durable, can make the raffinate gasification combustion in the steel cylinder, energy saving is environmental protection again, gets rid of major accidents such as fire, blast simultaneously, has overcome the existing defective of flow deviding type economizer.

The technical solution of the utility model is: be equiped with the drain fiber in a conduit, the upper end of conduit is provided with outlet nozzle, outlet nozzle top is provided with O-ring seal, the lower end of conduit is located in the spacing sheath, the bottom of spacing sheath is provided with bottom, be provided with Returnning spring between the end of conduit and the bottom, spacing sheath is provided with inlet opening near the bottom, and liquified petroleum gas cylinder gas-liquid interface top, conduit middle part is provided with inlet hole.

Good effect of the present utility model is as follows:

1, this apparatus structure is simple, and is sturdy and durable, and cost is lower, once mounting, and lifelong being benefited thoroughly solved the bottled gas raffinate and given all worries that the user brought.

2, use the utilization ratio that raffinate has fully improved liquid gas, the availability of every bottle of liquid gas has been improved more than 15%, thereby one bottle of liquid gas of every use, calculating the combustion gas expense that just can save 14-20 unit by present price, this also meets the policy guidance of creating conservation-minded society.

3, eliminated because of toppling over the hidden danger that accidents such as liquefied gas residue initiation fire, blast take place, improved the safety in utilization of bottled gas, also eliminated the pollution of raffinate simultaneously environment.

4, because of having changed grouping gasification in the original bottle of liquid gas, grouping derive in the uneven and bottle of the firepower that uses and produce a component and in press the bad phenomenon that significantly changes, improved stability in use, Security and the using effect of bottled gas.

5, under equal service condition, the firepower of liquid gas is concentrated more, strengthen, stablized.Improved using effect, shortened each gas time of using, the life cycle that has prolonged every bottle of gas has reduced inflation times, has reduced user cost.

6, after existing cylinder for liquefied gas is installed this device, reduce the limit of bottled gas significantly to the requirement of liquid gas component, thereby can simplify the manufacturing technique requirent of liquid gas, can adapt to the liquid gas use that multinomial alkane content ratio changes, thereby can reduce production costs significantly, make the production of liquid gas and use in create better economic benefit and social benefit.

Description of drawings

Accompanying drawing is a mounting structure schematic representation of the present utility model.

Embodiment

With reference to accompanying drawing, the utility model is to be equiped with drain fiber 5 in a conduit 4, the upper end of conduit is provided with outlet nozzle 3, outlet nozzle top is provided with O-ring seal 2, the lower end of conduit is located in the spacing sheath 10, and the bottom of spacing sheath is provided with bottom 13, is provided with Returnning spring 11 between the end of conduit and the bottom, spacing sheath is provided with inlet opening 12 near the bottom, and liquified petroleum gas cylinder gas-liquid interface top, conduit middle part is provided with inlet hole 8.

The utility model is installed in the cylinder for liquefied gas 6, when giving pneumatic inflation, under the gas pressure of inflator, conduit 4 compression reseting springs 11 and descending, liquid gas will be rapidly charges among the steel cylinder by the space between main valve 1 and the O-ring seal 2, because this space is enough big, therefore can not exert an influence to the pneumatic inflation process.After inflation finishes, because the effect of Returnning spring 11, conduit 4 is moved on rapidly, and shut the air inlet/outlet of main valve 1 by O-ring seal 2, the gas phase 7 of the liquid gas in the steel cylinder can not be overflowed by free air inlet/outlet from main valve.At this moment, the liquid phase part 9 of liquid gas is located at the liquid entering hole 12 inletting device inside of bottom from this device.Owing in the conduit drain fiber is housed, utilize the capillarity of this material, make the bottom of liquid phase part along the drain fiber from steel cylinder of liquid gas rise to the top of this device near main valve always.When using combustion gas, open main valve, the liquid gas gas phase part in the steel cylinder is under the inside and outside differential pressure effect of steel cylinder, and the inlet hole 8 that is located at gas-liquid interface top from this device enters this device, and, derive the steel cylinder burning by outlet nozzle and main valve and use along the rising of shuttling back and forth of the drain fiber in the conduit.This air-flow is in conduit in the uphill process, the liquid phase component that constantly will be contained in the drain fiber blows away and takes out of steel cylinder, so, the liquid gas of deriving steel cylinder by this device this moment no longer be stage by stage in the past, the gas of branch component derivation, but carry the liquefaction gas-liquid gas mixed airflow of a large amount of liquid phase fogs in the air-flow secretly, these by liquid phase components of being taken out of after entering external pipe and stove and accessory, gasifying burning rapidly under the environment of low pressure and high temperature externally.Thereby thoroughly handled the raffinate in the liquified petroleum gas cylinder, improved the effective rate of utilization of liquid gas and the stability that uses.

Measuring, steel cylinder is installed after this device, the volume of the liquid phase component of taking out of in the steel cylinder accounts for derives about 3% of volume, and these liquid phase components are after the derivation steel cylinder enters pressure governor, the overwhelming majority all gasifies rapidly and expand into 625 times gas of original volume, but the gaseous component of liquid gas is after deriving steel cylinder, because of its volume of decompression only expand into about original 4 times, therefore, the liquid phase of actual liquid gas of deriving in the steel cylinder and the ratio of gas phase are about 6.5: 1, that is to say that the liquid gas of deriving steel cylinder by this device is mainly based on liquid phase, the gas phase part mainly works to provide interior pressure gas stream and drag-out phase component.And liquid phase component be can be in steel cylinder the branch component derive, this just makes that deriving liquid gas of steel cylinder is by deriving near the stock blend composition, the component of derivation gas is uniform and stable.All the time keep a certain proportion of methane, ethane component in the steel cylinder thereby make, it is even to make that the interior saturated atmosphere pressure of bottle keeps relative stability, and also can not remain separately simultaneously to be difficult for vaporized component, till liquid gas is all used up in whole bottle.
