Abstract

A liquefied gas residual liquid gasifying device is in a double-cavity tube structure form. One of the cavities is an air outlet channel, the upper port of the air outlet channel can be connected with an air port of the steel cylinder angle valve, the other cavity is an air inlet channel, and the upper port of the air inlet channel is positioned at the upper part of the steel cylinder and communicated with the gas part in the steel cylinder. The lower opening of the double-cavity tube is close to the bottom of the steel cylinder and is used as a liquid inlet, and liquefied gas enters from the gas inlet, passes through liquid at the lower part of the pipeline and then flows from the gas outlet to the liquefied gas stove through the angle valve to be combusted. Thus, the residual liquid in the bottle can overflow along with the gas, and the accumulation of the residual liquid is avoided.

Description

Remained liquid gasified device double-cavity pipe type steel pot of LPG

The utility model belongs to technical field of living goods, is a kind of cylinder for liquefied gas vaporization device for raffinate.

General cylinder for liquefied gas in use, the liquid gas in the bottle can produce " layering " phenomenon by the different of proportion and boiling point, light specific gravity, boiling point composition low, easy vaporization gather the top (in fact a bottle internal upper part is a gaseous substance) at steel cylinder; And than great, boiling point is high, the composition that is difficult for vaporization is in the bottle bottom, with forming " raffinate " to the end, can't utilize.Along with the prolongation of service time, " raffinate " is more and more, until can't normally inflating use.For this reason, liquefied gas station have to regularly extract raffinate.This is the work of a trouble.In the place that does not have condition, the user have to outwell raffinate for own interests.So both wasted fuel, again severe contamination environment.

The purpose of this utility model is to design a kind of device that can make the vaporization of cylinder for liquefied gas raffinate simple in structure, easy to use, so that the liquid gas in the steel cylinder is made full use of, cuts the waste and pollutes.

People know, and blow in the liquid in container, can produce a kind of " pneumatic boiling " phenomenon.In this boiling process, will have that partially liq is vaporized and overflow together with gas.The utility model designs according to this principle exactly.Its structure is the two-chamber tubular type, and one of them cavity is an air outlet channel, and suitable for reading can the connection with the air outlet of steel cylinder bicker valve, another cavity is an intake duct, and the top that is positioned at steel cylinder suitable for reading partly communicates with gaseous state in the bottle.The end opening of double lumen tube is near the steel cylinder bottom.Can submerge in the raffinate of steel cylinder bottom, be liquid entering hole.Like this, the air-inlet cavity road junction of liquid gas from double lumen tube enters cavity during use, by the liquid of cavity bottom, then by the cavity of giving vent to anger, exports the liquid gas cooking stove burning to through angle valve.Because the discharge of liquid gas all will be passed through the liquid of steel cylinder bottom, thereby liquid is overflowed with gas, has avoided stockpiling of raffinate.

Above-mentioned double lumen tube can be made different structural type, and material can be used engineering plastics, also can use metallic material, as iron pipe.

Further describe its structure below in conjunction with drawings and Examples.

The vaporizing unit structural drawing that Fig. 1 is connected as a single entity for double lumen tube.

Fig. 2 is the sectional view of double lumen tube among Fig. 1.

Fig. 3 is the vaporizing unit structural drawing of two pipelines arranged side by side for double lumen tube.

Fig. 4 is the vaporizing unit structural drawing of U-shaped pipe for double lumen tube.

Wherein, 1 is the steel cylinder body, and 2 is cylinder angle valve, and 3 is double lumen tube, and 4 is the air-inlet cavity road junction, and 5 are the air inlet cavity, and 6 for giving vent to anger cavity, and 7 is the outlet chamber road junction, and 8 is the double lumen tube liquid entering hole, and 9 is ball float, and 10 is the ball float latch.

Embodiment 1, and according to illustrated in figures 1 and 2, double lumen tube is garden shape pipe, and the centre has vertical interlayer that pipeline is divided into the air inlet cavity 5 and the cavity 6 of giving vent to anger.This interlayer to the top of pipe is located to a lateral bending song air inlet cavity 5 to be blocked, and has a hole as air inlet road junction 4 at its downside, and the upper end of garden shape pipe is connected with the gas port of angle valve 2 as giving vent to anger road junction 7.Placement can be to be threaded, and also can be gluing connection.Garden shape pipe end opening to the bottom of steel cylinder 1, promptly constitutes required vaporizing unit as liquid entering hole 8.

In order to control the discharge of steel cylinder bottom liquid lng, influence normal combustion to prevent too much liquid lng from directly flowing out, a ball float can be set at the liquid entering hole place of garden shape double lumen tube, and below ball float be kept off in pipeline with latch 10.The diameter of ball float is slightly less than warp in the liquid entering hole, as shown in Figure 1.

But the double lumen tube injection molded of this structure.Its size dimension is as for can descend data: the height of length and steel cylinder adapts, and its end opening leaves steel cylinder bottom 3-5mm, prevents that the bottom foul from sucking.Garden pipe diameter and angle valve gas port are complementary, and are convenient to connect.Generally can be 16mm, pipe thickness can be 1.5～2mm, and air inlet road junction 4 diameters can be 4mm, and floating ball diameter can be 14mm.

Embodiment 2, and the double lumen tube vaporizing unit is two pipelines arranged side by side, is interconnected in the pipeline bottom, as shown in Figure 3.Wherein, a pipeline is the cavity 6 of giving vent to anger, and suitable for readingly is to be connected with the angle valve gas port of steel cylinder at the road junction 7 of giving vent to anger, and end opening is a liquid entering hole 8, to the bottom of steel cylinder.Another pipeline is slightly short, is air inlet cavity 5, and suitable for reading is suction port 4.

For reason same in the example 1, a ball float can be set at the liquid entering hole place.This structure can injection molded.Also can make of iron pipe.

Embodiment 3, and the double lumen tube vaporizing unit is the U-shaped pipeline, and an arm of U-shaped pipe is as air inlet cavity 5, and suitable for reading is import 4, and another arm is slightly long, and is suitable for reading for giving vent to anger road junction 7 as giving vent to anger cavity 6, is connected with the gas port of cylinder angle valve.Lower side at the U-shaped pipe has a hole, as liquid entering hole 8.
