Description

CHARGING GAS BOTTLE
Technical Field
The present invention relates to a charging gas bottle, and more particularly to a charging gas bottle provided with a charging valve, in which a mount cap, installed on an upper cap for protecting the valve and supporting the charging gas bottle during combustion of the gas contained therein when the charging gas bottle is charged with gas or installed in a gas appliance, is replaceable, and the valve is simply assembled with and disassembled from the upper cap.
Background Art Generally, after gas in charging gas bottles is completely used, the charging gas bottles are recharged with gas and are then used again. As shown in Fig. 15, a conventional charging gas bottle 100 comprises a main body 110 charged with gas by injecting the gas thereinto, an upper cap 120 connected to an upper end of the main body 110, a lower cap (not shown) connected to a lower end of the main body 110, a valve 60 installed on the upper cap 120 for charging and discharging gas into and from the main body 110 therethrough, and a mount cap 140 connected to the upper cap 120 outside a circumference of the valve 60 by a conventional welding method for protecting the valve 60 and supporting the main body 110 when the charging gas bottle 100 is charged with gas or installed in a gas appliance for combustion of the gas contained therein. After gas in the above-described conventional charging gas bottle 100 is completely used, the charging gas bottle 100 is recharged with gas through the valve 60 and is then used repeatedly, thereby being advantageous in that it increases economical efficiency. Recently, there have been proposed various types of charging gas bottles. Here, a valve is a critical component in these charging gas bottles.
Since the conventional charging gas bottles are repeatedly recharged with gas and are then used, the mount cap connected to the upper cap by a method, such as welding, for protecting the valve and supporting the main body of the charging gas bottle when the charging gas bottle is charged with gas or installed in a gas appliance for combustion of the gas contained therein, is frequently deformed by being crashed or broken due to a careless mistake by a user generated when the charging gas bottle is transferred, used frequently, or repeatedly charged.
The above deformation of the conventional mount cap connected to the upper cap of the conventional charging gas bottle causes danger in safety due to instability of the mount cap during combustion of the gas contained therein according to the use of the charging gas bottle, and raises a difficulty in recharging gas into the charging gas bottle. One type of conventional valves installed in the charging gas bottle includes a gas-discharging valve installed on an upper portion of a main body of the charging gas bottle and a gas-charging valve installed on a lower portion of the main body of the charging gas bottle. This type of the conventional valves has a complicated structure and increases production costs .
Further, another type of conventional valves is installed on the upper portion of the main body of the charging gas bottle, and serves both to charge and discharge gas into and from the charging gas bottle. In case that the charging gas bottle is provided with this type of conventional valve, a charging apparatus generally employs a continuous rotary type charging method, thus being incapable of achieving quick charging of gas into the charging gas bottle.
That is, liquefied gas in a high-pressure and low- temperature state is charged into and discharged from the above-described conventional charging gas bottles. Since the charging and discharging of gas into and from the charging gas bottle are carried out through the same route, the gas valve of the charging gas bottle is easily worn down, thereby causing gas leakage. Accordingly, a packing in the valve must frequently be replaced with a new one.
Further, in the conventional charging bottle provided with only a single valve serving both to charge and discharge gas into and from the charging gas bottle, a common orifice of the valve has a small diameter. The small diameter of the common orifice of the valve does not obstruct the discharging of gas from the charging gas bottle. However, when the charging gas bottle is charged with liquefied gas in a high-pressure and low-temperature state, the small diameter of the common orifice of the valve requires a long period of time for recharging the charging gas bottle with the gas, thus causing a difficulty in achieving quick charging of gas into the charging gas bottle .

Best Mode for Carrying Out the Invention
Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings .
Fig. 1 is a schematically exploded perspective view of a charging gas bottle in accordance with a first embodiment of the present invention. Fig. 2 is a schematically assembled longitudinal-sectional view of the charging gas bottle of Fig. 2.
As shown in Figs. 1 and 2, a charging gas bottle 100 comprises a main body 110 charged with gas by injecting the gas thereinto, an upper cap 120 connected to an upper end of the main body 110, a lower cap (not shown) connected to a lower end of the main body 110, a valve 60 installed on the upper cap 120 for charging and discharging gas into and from the main body 110 therethrough, and a mount cap 140 connected to the upper cap 120 outside a circumference of the valve 60 for protecting the valve 60 or installed on a gas appliance for supporting the main body 110 during combustion of the gas contained therein. Herein, in case that the mount cap 140, connected to the upper cap 120 for protecting the valve 60 or installed on the gas appliance for supporting the main body 110 during combustion of the gas contained therein, is distorted or damaged due to a user' s careless mistake encountered during conveyance or use of the charging gas bottle 100, the distorted or damaged mount cap 140 is simply and easily replaced with a new one.
The charging gas bottle further comprises a fixation cap 10 including a connection plane 12 connected to an upper surface of the upper cap 120, and a support plane 14 extended from the connection plane 12 and bent upwards, which are integrally formed, and a groove 15, obtained by the connection plane 12 and the support plane 14, to which an insertion portion 142, bent downwards, of the mount cap 140 is detachably and fixedly inserted by a general interference fit method. The fixation cap 10 is fixedly connected to the upper cap 120 by a general welding method.
Thereby, using the mount cap 140, of which the insertion portion 142 is detachably inserted into the groove 15 of the fixation cap 10 connected to the upper cap 120 by the welding method, gas is charged into the charging gas bottle 100 by an injection pipe of a known gas charging apparatus. Further, the mount cap 140 serves to support the charging gas bottle 100 when the charging gas bottle 100 is installed in a conventional gas appliance so as to use the gas filling the charging gas bottle 100 for combustion of the gas contained therein.
After the charging gas bottle 100 of the present invention is used for various purposes by means of the mount cap 140 inserted into the groove 15 of the fixation cap 10, in case that the mount cap 140 is deformed, such as distortion or damage, due to a user's careless mistake caused by conveyance and use of the charging gas bottle 100, the distorted or damaged mount cap 140 cannot be used for the above purposes and there is a danger of gas leakage or explosion when the charging gas bottle 100 is installed in the gas appliance.
Accordingly, after the deformed mount cap 140 fixedly inserted into the groove 15 of the fixation cap 10 by the interference fit method is separated from the groove 15, a new mount cap 140 is simply and conveniently inserted into the groove 15. That is, it is possible to conveniently replace the deformed mount cap 140 with a new one, thereby increasing the utility of the charging gas bottle 100 and allowing the charging gas bottle 100 to be safely used for a long period of time.
Fig. 3a is a schematically exploded perspective view of a charging gas bottle in accordance with a second embodiment of the present invention. Fig. 3b is a schematically assembled longitudinal-sectional view of the charging gas bottle of Fig. 3a.
As shown in Figs. 3a and 3b, in order to more firmly fix the mount cap 140 into the groove 15 of the fixation cap 10 connected to the upper cap 120, a bridging rib 22 extends from a mounting flange 143 of the mount cap 140 and bends toward a lower end of the mounting flange 143, and a plurality of hooked segments 20 are formed on the support plane 14 of the fixation cap 10 such that the hooked segments 20 are bent in an arc shape and have elasticity. Here, terminals of the hooked segments 20 are caught by the bridging rib 22 so that the mount cap 140 is detachably fixed to the fixation cap 10.
Thereby, edge portions of the mount cap 140 are pushed into the support plane 14 of the fixation cap 10 by means of the hooked segments 20 formed thereon, thus allowing the hooked segments 20 to be elastically connected to the bridging rib 22 extending from the lower end of the mounting flange 143 of the mount cap 140.
Accordingly, compared to the interference fit method of the mount cap 140 in accordance with the first embodiment, since the hooked segments 20 of the charging gas bottle 100 in accordance with the second embodiment support the bridging rib 22 formed on the lower end of the mounting flange 143, the mount cap 140 is more firmly fixed to the fixation cap 10. Fig. 4a is a schematically exploded perspective view of a charging gas bottle in accordance with a third embodiment of the present invention. Fig. 4b is a schematically assembled longitudinal-sectional view of the charging gas bottle of Fig. 4a.
As shown in Figs. 4a and 4b, in order to more simply and firmly fix the mount cap 140 into the groove 15 of the fixation cap 10 connected to the upper cap 120, a plurality of protrusions 32 are formed on an external surface of the insertion portion 142 of the mount cap 140 by a pressing method such as a conventional embossing process, and a plurality of through holes 30 are formed through the support plane 14 of the fixation cap 10 by a conventional pressing process such that the through holes 30 correspond to the protrusions 32, thereby allowing the mount cap 140 to be detachably fixed to the fixation cap 10.
Accordingly, since the protrusions 32 are inserted into the corresponding through holes 30 by simple manipulation in the third embodiment, the mount cap 140 is more simply and firmly attached to the fixation cap 10.
Fig 5a is a schematically exploded perspective view of a charging gas bottle in accordance with a fourth embodiment of the present invention. Fig. 5b is a schematically assembled longitudinal-sectional view of the charging gas bottle of Fig. 5a. As shown in Figs. 5a and 5b, in order to more firmly fix the mount cap 140 to the fixation cap 10 connected to the upper cap 120, a fastening threaded portion 42 is formed in a spiral shape on the external surface of the insertion portion 142 of the mount cap 140, and a fixing threaded portion 40 is formed in a spiral shape on the support plane 14 of the fixation cap 10 so that the fixing threaded portion 40 corresponds to the fastening threaded portion 42, thereby allowing the mount cap 140 to be detachably fixed to the fixation cap 10.
Accordingly, since the mount cap 140 is detachably fixed to the fixation cap 10 by a screwing coupling method, the mount cap 140 is more simply and firmly attached to the fixation cap 10. Fig. 6 is an exploded perspective view of a charging valve of the charging gas bottle of the present invention. Fig. 7 is an assembled longitudinal-sectional view of the charging valve of the charging gas bottle of the present invention. As shown in Figs. 6 and 7, the charging gas bottle
100, in which the upper cap 120 and the lower cap (not shown) are connected to the upper and lower ends of the main body 110 and the valve 60 is installed on the upper cap 120 for charging and discharging liquefied gas in a high-pressure and low-temperature state into and from the main body 110 therethrough, comprises a receiving unit 50 provided with a groove 54 including a threaded portion 53b formed in a spiral shape on an internal surface thereof and an opening so that a main body 610 of the valve 60, which will be described later, is connected to the upper cap 120 by inserting the main body 610 into the opening and screwing the main body 610 onto the threaded portion 53b.
The valve 60 includes the main body 610, and a gas charging and discharging unit 620. The main body 610 includes a threaded portion 53a formed in a spiral shape on an external surface thereof and screwed onto the threaded portion 53b of the receiving unit 50 by means of an airtight member 55, a passage 615 formed at a central portion thereof such that a width of an upper portion of the passage 615 is smaller than that of a lower portion of the passage 615, a fixture 618 provided with an insertion hole 616 formed therethrough and screwed onto a first flight 614a of the passage 615, and a packing 617 for fixing the fixture 618 to the passage 615. The gas charging and discharging unit 620 includes a charging pin 621 provided with a spring 6210b located on the bottom of the passage 615, a support flange 621c supported by the spring 6210b and a seal ring 621d connected to an upper end of the charging pin 621, and a discharging pipe 622 provided with an inlet/outlet route 622a separated from the charging pin 621 by a designated distance and a through hole 622b located on the upper end of the packing 617 so that the through hole 622b is connected to the inlet/outlet route 622a, and supported by a second flight 614b of the passage 615 by means of a lower surface of a blind flange 622c and a spring 621b.
A gas guidance pipe 130 is attached to a lower end of the main body 610 of the valve 60 by a connector 80 so that the gas guidance pipe 130 is connected to the passage 615 and accommodated by the main body 110 of the charging gas bottle 100.
Thereby, the main body 610 of the valve 60 is screwed onto the receiving unit 50 formed on the upper cap 120, thus being simply assembled with and disassembled from the upper cap 120 of the charging gas bottle 100. Further, fixture 618 is simply assembled with and disassembled from the upper end of the passage 615 of the main body 610 of the valve 60, thus allowing the valve 60, which is damaged or failed, to be easily repaired or replaced with a new one.
Preferably, an upper surface of the charging pin 621 is provided with an insertion groove 621a formed thereon so that a terminal of an injection pipe is easily inserted into the insertion groove 621a in order to press the charging pin 621, and has a lower level than that of an upper surface of the discharging pipe 622, thus preventing interference between the charging pin 621 and the discharging pipe 622 when gas is charged into and discharged from the main body 110 of the charging gas bottle 100 by means of the charging pin 621 and the discharging pipe 622, thereby achieving effective gas charging and discharging of the charging gas bottle 100. Fig. 8 is a longitudinal-sectional view of the charging gas bottle of the present invention, into which gas is charged by means of the valve.
As shown in Fig. 8, when an inlet of a known charging apparatus contacts the upper end of the fixture 618 of the valve 60 and an injection pipe of the inlet drops the charging pin 621 of the gas charging and discharging unit 620, the seal ring 621d connected to the upper surface of the support flange 621c of the charging pin 621 supported by the spring 6210b is separated from the lower surface of the discharging pipe 622. Thereby, liquefied gas in a high- pressure and low-temperature state is introduced into the inlet/outlet route 622a formed between the charging pin 621 and the discharging pipe 622 through the injection pipe of the inlet of the charging apparatus, and then flows into the passage 615 of the main body 610 of the valve 60.
Thereafter, the liquefied gas introduced into the passage 615 of the main body 610 of the valve 60 fills the main body 110 of the charging gas bottle 100 through the gas guidance pipe 130 connected to the main body 110 by the connector 80. Accordingly, when the main body 110 of the charging gas bottle 100 is charged with liquefied gas in a high-pressure and low-temperature state, the liquefied gas is introduced into the main body 110 of the charging gas bottle 100 through the charging pin 621 formed in the valve 60, the expanded inlet/outlet route 622a and the passage 615, thereby achieving quick-charging of gas into the main body 110 of the charging gas bottle 100.
When the main body 110 of the charging gas bottle 100 is charged with liquefied gas, the discharging pipe 622 is supported by the second flight 614b of the passage 615 by means of the spring 621b, and the through hole 622b of the discharging pipe 622 is cut off by the packing 617, thereby preventing the generation of gas leakage. Fig. 9 is a longitudinal-sectional view of the charging gas bottle of the present invention, from which gas is discharged by means of the valve.
As shown in Fig. 9, when the charging gas bottle 100 charged with the liquefied gas in a high-pressure and low- temperature state as shown in Fig. 8 is used, the charging gas bottle 100 is installed in a known combustion appliance so that the fixture 618 of the valve 60 contacts a receiving unit of the combustion appliance. Thereby, the discharging pipe 622, supported by the second flight 614b of the passage 615 by means of the spring 621b, of the valve 60 is pressed by the receiving unit and is transferred in the direction of the arrow so that the through hole 622b is separated from the packing 617, and the liquefied gas in a low-temperature state in the charging gas bottle 100 passes through the gas guidance pipe 130 and the passage 615, is discharged through the through hole 622b and the inlet/outlet route 622a, and is then supplied to the combustion appliance.
Here, the charging pin 621 located in the discharging pipe 622 is supported by the spring 6210b located on the bottom of the passage 615, and contacts the bottom surface of the discharging pipe 622 by the seal ring 621d connected to the upper surface of the support flange 621c, thereby blocking the end of the inlet/outlet route 622a and preventing the discharged gas from flowing backwards into the charging gas bottle 100.
Accordingly, the liquefied gas in a low-temperature state filling the main body 110 of the charging gas bottle 100 passes through the gas guidance pipe 130 and is then discharged to the outside through the passage 615, the through hole 622b and the inlet/outlet route 622a.
Since the upper surface of the charging pin 621 has a lower level than that of the upper surface of the discharging pipe 622 as described above, when the valve 60 is installed on the receiving unit of the combustion appliance, it is possible to press only the discharging pipe 622 without pressing the charging pin 621. Fig. 10 is a schematically exploded perspective view of a charging gas bottle in accordance with a fifth embodiment of the present invention. Fig. 11 is a schematically assembled longitudinal-sectional view of the charging gas bottle of Fig. 10.
As shown in Figs. 10 and 11, the valve 60, which is installed on the upper cap 120 for charging or discharging gas into and from the charging gas bottle 100, is simply assembled with and disassembled from the upper cap 120 by the screwing method as shown in Fig. 6, and serves to achieve quick charging of gas into the charging gas bottle 100 easily, thereby allowing components in the valve 60 to be easily replaced with new components when the valve 60 is assembled with the upper cap 120.
The valve 60 includes the main body 610, and the gas charging and discharging unit 620. The main body 610 includes a head 611 inserted into the groove 54 of the upper cap 120 and supported by the upper surface of the groove 54, a second airtight member 612 connected to a lower surface of the head 61, the passage 615 provided with the threaded portion 53a formed in a spiral shape on an external surface thereof and a flight formed therein, the fixture 618 provided with the insertion hole 616 formed therethrough and screwed onto the flight 614 of the passage 615, and the packing 617 for fixing the fixture 618 to the passage 615.
The gas charging and discharging unit 620 includes the charging pin 621 provided with the spring 621b located on the bottom of the passage 615, the support flange 621c supported by the spring 621b and the seal ring 621d connected to the upper end of the charging pin 621, and the discharging pipe 622 provided with the inlet/outlet route 622a separated from the charging pin 621 and the through hole 622b located on the upper end of the packing 617 so that the through hole 622b is connected to the inlet/outlet route 622a.
A fixation body 70 is located on a lower surface of a receiving hole of the upper cap 120, and provided with an airtight packing 71 located on the bottom of the fixation body 70 so that the bottom of the main body 610 of the valve 60 contacts the airtight packing 71 and the external surface of the main body 610 is screwed onto the internal surface of the fixation body 70, and a supply hole 72 formed through the bottom of the fixation body 70 so that the supply hole 72 is connected to the passage 615. The gas guidance pipe 130 is attached to the lower end of the fixation body 70 by the connector 80 using the known screwing method so that the gas guidance pipe 130 is connected to the supply hole 72.
Thereby, the main body 610 of the valve 60 including the gas charging and discharging unit 620 is screwed onto the fixation body 70 fixed to the lower surface of the receiving hole of the upper cap 12, thus being simply and detachably connected to the fixation body 70. Thereby, it is possible to simply install the valve 60 on the upper cap 120 by means of the fixation body 70 without any additional process.
Further, various components, such as various packings, seal rings and airtight packings, located in the main body 610 of the valve 60 are simply replaced with new components by separating the fixture 618 from the main body 610 of the valve 60.
In the constitution of the charging gas bottle 100 in accordance with the fifth embodiment, charging and discharging of gas into and from the charging gas bottle 100 by means of the valve 60 are the same as those of the constitutions of the charging gas bottle 100 in accordance with the earlier embodiments. However, the structure of the charging gas bottle 100 in accordance with the fifth embodiment is advantageous in that it has a simpler structure and it is possible to more easily repair and replace the components of the valve 60 with new components. Fig. 12 is a schematically exploded perspective view of a charging gas bottle in accordance with a sixth embodiment of the present invention. Fig. 13 is a schematically assembled longitudinal-sectional view of the charging gas bottle of Fig. 12. As shown in Figs. 12 and 13, since the gas guidance pipe 130 connected to the passage 615 located at the lower end of the main body 610 of the valve 60 by the connector 80 is charged with the liquefied gas in the low-temperature state, the gas is not leaked from the gas guidance pipe 130, which is dipped in the liquefied gas when the charging gas bottle 100 is used. Thereby, the gas guidance pipe 130, under the condition that it is charged with the liquefied gas, must be located in the main body 110 of the charging gas bottle 100.
The connector 80 is provided with a threaded portion 53c formed in a spiral shape on an external surface thereof, and the main body 610 of the valve 60 is provided with a threaded portion 53d in a spiral shape formed on a portion thereof corresponding to the threaded portion 53c so that the connector 80 is screwed onto the main body 610, thereby allowing the gas guidance pipe 130 to be connected to the passage 615 by means of the connector 80 at a desired position. Accordingly, under the condition that the position of the charging gas bottle 100 to be used is determined, the gas guidance pipe 130 is firmly connected to a desired position of the charging gas bottle 100 by means of the screwing using the connector 80. Further, in order to more firmly connect the gas guidance pipe 130 to the passage 615 of the main body 610 of the valve 60 by the connector 80, it is preferable to form an expanding portion 131, which is expanded from an end of the gas guidance pipe 130, connected to the passage 615, and to form a connection portion 610a, of which a width of a lower portion is smaller than that of an upper portion, on an end of the passage 615 corresponding to the expanding portion 131.
Accordingly, the expanding portion 131 of the gas guidance pipe 130 is more firmly connected to the connection portion 610a of the passage 615 by the connector 80 screwed onto the lower end of the main body 610 of the valve 60.
Fig. 14 is a longitudinal-sectional view of another embodiment of a connection portion of the charging gas bottle of the present invention.
As shown in Fig. 14, the receiving unit 50 includes the groove 54 for inserting the main body 610 of the valve 60 into the upper cap 120 therethrough, and a fastening nut 52 connected to the groove 54 by a general welding method so that the fastening nut 52 is screwed onto the threaded portion of the main body 610 of the valve 60.
Thereby, since a process for forming the groove 54 and the threaded portion on an inner surface of the groove 54 is easily performed in order to screw the valve 60 onto the upper cap 120, it is possible to firmly assemble and dissemble the main body 610 of the valve 60 into and from the upper cap 120 by the screwing.
