Description

Non-residual P.L.G. steel cylinder

The utility model relates to a kind of pressurized container that can allow liquid gas fully discharge, particularly a kind of no raffinate liquefied petroleum ga steel cylinder.

At present, liquefied petroleum ga steel cylinder is made up of bottle and the angle valve that is loaded on bottleneck, by angle valve control feed liquor and exhaust.Bottle gas causes and always leaves about 1/5th raffinate in the bottle because of heavy ends are difficult for gasification, can't burn, and causes the waste of the energy on the one hand, increases on the other hand to inhale residual manpower and materials of falling residual and round transport.Though the method with the outer heating of bottle can make a part of raffinate gasification, does not meet the safety operation standard, is not allowed to.

The purpose of this utility model is, provides a kind of and can make heavy ends with gas discharging, no raffinate liquefied petroleum ga steel cylinder safe in utilization.

The utility model is provided with a gas-liquid mixing device in liquefied petroleum ga steel cylinder, this device comprises an overcoat that is tightly connected with angle valve, a plunger and a displacement Returnning spring thereof that is contained in the overcoat, a pick-up tube, a filter, overcoat top is the negative cavity of diameter less than plunger diameter, the overcoat side has liquid filling pore along a circumference, there is fixedly connected bottom the overcoat lower end, have imbibition pore and breeder tube on the bottom, the plunger end mask has breeder tube and a drainage micropore that is positioned at the center, the drainage micropore lower end pick-up tube that is tightly connected, the pick-up tube lower end connects filter, and spring housing is in the pick-up tube upper end.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model overall structure schematic representation.

Fig. 2 is a gas-liquid mixing apparatus structure schematic representation of the present utility model.

As shown in Figure 1, the utility model does not have a gas-liquid mixing device 2 is set in the raffinate steel cylinder 3, and 1 is angle valve among the figure, and 6 are the outlet reduction valve, and 4 is LPG (liquefied petroleum gas) residual liquid, and 5 is the filter of gas-liquid mixing device.

As shown in Figure 2, gas-liquid mixing device in the steel cylinder is by overcoat 13, plunger 10, spring 12, pick-up tube 15 and filter (among Fig. 1 shown in 5) are formed, overcoat 13 is connected with angle valve 1 thread seal, overcoat top is negative cavity 8, its diameter is less than plunger 10 diameters, the overcoat side has liquid filling pore 11 along a circumference, there is the bottom 14 that is threaded the overcoat lower end, have imbibition pore 16 and breeder tube 17 on the bottom, plunger 10 end faces have breeder tube 7 and a drainage micropore 9, and the drainage micropore is positioned at the plunger center, its lower end pick-up tube 15 that is tightly connected, the pick-up tube lower end connects filter (among Fig. 1 shown in 5), and spring 12 is enclosed within on the pick-up tube 15 of bottom 14 tops.

The utility model using process is as follows: when irritating liquid, plunger 10 end faces of gas-liquid mixing device move down in the steel cylinder, and liquid phase petroleum gas enters in the steel cylinder through overcoat side liquid filling pore 11.Filling liquid is finished, and closes angle valve, and spring 12 is sealed overcoat top negative cavity 8 with plunger jack-up at this moment.When opening angle valve and the combustion gas of kitchen range valve, gas phase petroleum gas forms one air-flow outside overcoat top negative cavity output bottle by the breeder tube on overcoat bottom and the plunger 17,7 in the steel cylinder, form pressure difference in the plunger upper and lower cavity this moment, according to bernoulli principle, the liquid phase petroleum gas that is compressed in steel cylinder bottom is through filter (among Fig. 1 shown in 5), pick-up tube 15,9 sucking-offs of plunger center drainage micropore, volume expansion rapidly forms spray form, mixes the output burning with gas phase petroleum gas air-flow.So the heavy ends raffinate of former difficult gasification all can be taken out of by high velocity air more than 95% in the steel cylinder, fully burning utilizes.The utility model does not change original filling liquid of steel cylinder and usage mode, does not only stay raffinate, and the stream pressure of output within the specific limits, and is safe and reliable.

For making the utility model raffinate atomizing effect better, further feature is, as shown in Figure 2, plunger 10 ends of gas-liquid mixing device have tapered side, overcoat 13 negative cavities 8 lower ends have tapered side with matching, its effect is: liquid can flow in the steel cylinder by the liquid filling pore 11 of overcoat side downwards from the plunger tapered side rapidly when irritating liquid, keeps drainage micropore 9 unobstructed, guarantees the sealing between plunger and the overcoat during use.

Claims (2)

1, no raffinate liquefied petroleum ga steel cylinder, it is characterized in that being provided with in the bottle gas-liquid mixing device, this device comprises an overcoat that is tightly connected with angle valve, a plunger and a displacement Returnning spring thereof that is contained in the overcoat, a pick-up tube, a filter, overcoat top is the negative cavity of diameter less than plunger diameter, the overcoat side has liquid filling pore along a circumference, there is fixedly connected bottom the overcoat lower end, have imbibition pore and breeder tube on the bottom, the plunger end mask has breeder tube and a drainage micropore that is positioned at the center, the drainage micropore lower end pick-up tube that is tightly connected, the pick-up tube lower end connects filter, and spring housing is in the pick-up tube upper end.
