Abstract
A non-residual device of LPG cylinder of the utility model is accomplished by a residual liquid evacuation device installed in the LPG cylinder. The device is a hollow tube which holds the valve plug on the top and holds down the basal plane of the steel cylinder, the uppermost part is equipped with an exhaust groove, and the bottom is equipped with a liquid feeding bore. Because of the greater atmospheric pressure in the steel cylinder, the residue gas is expelled firstly from the liquid feeding bore on the bottom of the steel cylinder, and then all of liquefied petroleum gas is expelled. The device with simple structure can be equipped without any changes to the steel cylinder, without heating, electric energy and pumping. The utility model is an energy-saving product quite safe and reliable to use and is a great program benefiting hundreds of millions of people with the value of wide popularization and application.
Description
The utility model relates to a kind of oil liquefied gas steel cylinder device, especially oil liquefied gas steel cylinder no residue device.
At present, use liquefied petroleum gas to be popularized in China, still, leave more raffinate after the use, can't after-flame, cause energy waste, this problem can not get good solution all the time.Though solve the raffinate problem thousand and one way is arranged also, as inflate method, heating ... but all undesirable, and exist with the factor of many danger.
The purpose of this utility model provides a kind of oil liquefied gas steel cylinder no residue device, and the leftover problem of the solution raffinate that it can be very desirable does not heat, do not inflate, and not electricity consumption, structure is very simple, and quite safe.
The purpose of this utility model is achieved in that in cylinder for liquefied gas (15), and this no residue device (13) of directly packing into allows its upper end withstand on the lower end surface of valve plug (12), and the lower end withstands on the interior bottom plane of cylinder for liquefied gas (15); This no residue device, comprise a metal hollow tube (4), one end of hollow tube (4) is installed the eel-like figure termination (3) that middle air channel (2) is arranged, one end of eel-like figure termination has a boss ring (2-2) and abutting end (2-3), boss ring (2-2) bumps with hollow tube (4) and connects the location, its external diameter and hollow tube external diameter are equal to, abutting end (2-3) cooperates fixing with hollow tube (4) internal diameter, the middle waist diameter of eel-like figure termination (3) is less than the diameter of boss ring, the other end of eel-like figure termination (3), be the termination (2-1) of a diameter greater than middle waist diameter, the termination has one to be tapering projection end face, end face has multiple tracks groove (1), the other end of hollow tube (4) inserts in the sleeve pipe (7), sleeve pipe and hollow tube (4) are fixedly connected, be fitted with the telescopic pipe (9) of hollow in the other end of sleeve pipe (7), one end of telescopic pipe (7) is fixedly connected with an end of spring (6) with fixing pin (8), the other end of telescopic pipe has inlet opening (10) in the place near end face, the other end of spring (6) is fixedly connected by the same hollow tube of fixing pin (5) (4).Both ends of the spring is fixed like this, and telescopic pipe (9) can free telescopic slide.
Owing to adopted such scheme not heat, not electricity consumption is not inflated and simple in structure, and does not have any potential safety hazard, can effectively solve liquid gas noresidue problem, thereby reach purpose of energy saving.
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Figure one is a structural principle schematic representation of the present utility model.
Figure two is that size of the present utility model is amplified three times left view.
Figure three is installed in the schematic representation of the practicality in the steel cylinder for the utility model:
Among the figure, 1. groove 2. air flue 2-1. termination 2-2. boss ring 2-3. abutting ends 3. eel-like figure terminations 4. hollow tubes, 5. fixing pins, 6. springs, 7. sleeve pipes 8. fixing pins 9. telescopic pipes 10. inlet openings 11. steel cylinder switch knobs 12. valve plugs 13. economizers 14. liquid gas 15. steel cylinders 16. air-flows 17. air outlet flues
In an embodiment, the lower end surface of valve plug (12) is about 600 millimeters to the distance of steel cylinder (15) inner bottom surface, the total length of this no residue device (13) is greater than 600mm, after packing into this device in the steel cylinder, because the elastic force effect of spring (6), the bottom plane of valve plug (12) is tightly withstood in termination (2-1), telescopic pipe (9) tightly withstands the bottom plane of steel cylinder (15), when valve plug (12) is mentioned when being higher than air outlet flue (17), liquid gas flow (16) promptly can enter air flue (2) by inlet opening (10), discharges from air outlet flue (17).Because in the steel cylinder (15) higher air pressure is arranged all the time, liquid gas does not have other source again, only can at first discharge raffinate, until at last all liquid gas being discharged from the inlet opening (10) of steel cylinder lower.Because inlet opening (10) will have a bit of distance from the bottom plane of steel cylinder (15), must not be less than 1mm, the liquid gas that is lower than inlet opening (10) promptly can be retained, and meeting like this can not be the regulation of the whole emptyings of liquid gas.The middle eel-like figure part of eel-like figure termination (3) must have enough length, and its length is: start at from air outlet flue (17) upper edge on top, and the bottom must surpass the last inwall of steel cylinder, must not be less than 1 millimeter.Because when aeration, valve plug (12) is raised, and termination (2-1) promptly exceeds air outlet flue (17), when liquid gas enters steel cylinder (15) by air outlet flue (17), promptly can not hindered, can be smooth and easy and pour into rapidly.The diameter of the middle eel-like figure part of eel-like figure termination (3) is: between 1.5 millimeters～4.5 millimeters, purpose also be for airflow smooth without hindrance.
