Description

Gas depressing apparatus for butane burner

The present invention relates to a gas decompression device for a butane combustion apparatus, and more particularly, various butane gas combustion apparatuses (for example, a gas lamp, a gas lamp, a frying pan, a gas stove, etc.) connected to a butane can of low gas pressure. The present invention relates to a gas decompression device for a butane combustion apparatus, which can be safely used without fear of breakage or failure of the combustion apparatus for butane gas due to a pressure difference even when the gas is connected to an Elphage gas container having a higher gas pressure.

In general, the gas pressure of disposable butane cans is less than 5㎏ / ㎠ at 35 ℃ according to the Korea Gas Safety Corporation, and the gas pressure in small LPI container used mainly for outdoor use is about 12㎏ / ㎠ at 35 ℃. The gas pressures of the and LP container have significant differences.

However, butane cans are thrown away after one-time use as a single-use can contaminate the environment, increase the amount of waste discharge, cause explosion accidents due to residual gas in the can, and social problems caused by adolescent gas intake. Due to its relatively small portable convenience and easy purchase anywhere, it is still mainly used in homes and outdoors, and combustion apparatuses are mainly used for butane gas.

On the other hand, the LPG gas is not produced and sold in a small size like a butane can, and the container is also large enough to be carried in a vehicle, which is not easy to carry and its frequency of use is not as common as that of a butane can. Various combustors are not diverse.

Therefore, due to the gas pressure difference, the combustion apparatuses for the butane gas and the LPG gas are separately produced and used, respectively, and as a result, there is no mutual compatibility between the combustion apparatuses and there is no alternative to suppressing the use of the butane can. The consumption of canned butanes, which causes many social problems due to use, will naturally increase.

Therefore, the present invention was devised to solve such problems in the related art, and an object of the present invention is to connect the butane can combustion apparatuses, which are currently dominated, to an LP gas container having a higher gas discharge pressure and a lower price. The present invention provides a gas decompression device for a butane combustion device, which can be safely used without fear of breakdown, damage or safety accident of the combustion devices.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail as follows.

Figure 1 is an assembled side cross-sectional view of the gas passage of the gas decompression device for the butane can combustion mechanism according to the present invention, as shown in the longitudinal direction of the decompression body 1 as shown in the inlet ( 2) and the outlet portion 3 are separated and formed around the partition 4, and the screw portion 2a of the inlet portion 2 is fastened to the coupler 5 for an LP gas container having a higher gas pressure than the butane can. As the threaded portion 3a of the outlet portion 3, a connecting pipe 6, in which various types of butane gas combustion mechanisms are installed, such as an unillustrated gas, a gas burner, a gas lamp, and a gas stove, The spheres are generally equipped with a gas valve.

As shown in FIG. 1, the pressure reducing chamber 7 and the piston chamber 8 are separately formed on the side surfaces of the pressure reducing body 1 in the orthogonal direction to the inlet and outlet portions 2 and 3, respectively. The gas inlet hole 9 is formed in the partition wall between the 7 and the inlet part 2, and the valve operation hole 7a and the outlet part of the partition 4 formed in the horizontal direction of the decompression chamber 7 3, a gas discharge hole 9 through which gas is depressurized and discharged is formed as a partition wall between the walls, and a partition wall between the outlet part 3 and the piston chamber 8 is attached to various gas combustion mechanisms 5a. Gas backflow holes 11 are formed in the outlet portion 3 to allow the residual discharge gas to flow back into the piston chamber 8 during the locking operation of the valve (not shown).

On the other hand, in the pressure reducing chamber (7) in connection with the piston means to be described later through the inlet (2) and the gas inlet 9 through the inlet to the pressure reducing chamber (7) valve for down discharged to the predetermined pressure The means 12 are provided with a screw cap 13 for sealing the decompression chamber 7 and a horizontal edge of the distal end of the screw cap 13 while being horizontally installed with respect to the screw cap 13 via a spring 14. The valve body 15 is inserted into the valve groove 7a in a state that the 15a is inserted into and supported in the through hole 4a of the partition 4 so as to open or shut off the gas discharge hole 10 and through the fire. It is comprised by the packing 15b of the rubber material inserted in the edge bar 15a for sealing the ball 4a.

In addition, the piston chamber 8 is provided with a piston means 16 for advancing and controlling the valve body 15 of the valve means 12 using the pressure of the countercurrent gas when the valve of the combustor is shut off. 8) is composed of a screw cap (17) for sealing and a piston (18) installed elastically by a spring (18) with respect to the screw cap (17) and an O-ring (19a) for airtightness on the outer peripheral surface, In addition, a vent hole 17a formed by a screw cap 17 and a rim support groove 19b formed in the front surface of the piston 19 for discharging the compressed air according to the operation of advancing and retracting the piston 19 are included.

When the decompression state of the LLP gas using the decompression device according to the present invention configured as described above is as follows.

As shown in FIG. 2, first, the coupler installed as the inlet part 2 in the state of fastening and fixing any one of the butane can combustion mechanisms not shown as the connecting pipe 6 of the outlet part 3 of the decompression body 1. Use (5) to fasten and fix the LPI gas container (not shown).

Then, after opening the valve attached to the LP gas container, and then opening the valve attached to the combustion mechanism, the high pressure LPG gas is moved to the inlet portion 2 of the decompression body 1 by the discharge pressure. At the same time it is stored in the primary inlet into the pressure reduction chamber (3) through the gas inlet (9).

In addition, the gas introduced into the decompression chamber 3 is discharged in a state of being lowered to a predetermined pressure through a gas discharge hole 10 formed as a partition wall between the valve groove 7a and the outlet part 3. The gas discharge hole 10 is opened by the valve body 15 blocking the gas retreating by a predetermined distance within the range of the discharge groove 7a. That is, in the valve body 15 which blocked the gas discharge hole 10, the front-end | tip part of the edge rod 15a inserted in the through-hole 4a is supported by the edge receiving groove 19b of the piston 19 as shown in FIG. Since the gas flow is installed through the furnace piston chamber 8, the reverse flow gas, which has been compressed in the piston chamber 8 due to the combustion operation of the gas, first rapidly exits to the outlet portion 3 through the gas backflow hole 11. The reaction force of the spring 18 interposed between the output and the rear threaded cap 17 causes the piston 19 to move forward in the piston chamber 8 toward the partition 4, whereby the front deflection groove ( The rim 19 supported by 19a is also forcibly pushed by the movement distance, and at the same time, the valve body 15 inserted into the valve groove 7a in the decompression chamber 7 also lifts the rear spring 14. While being forced to retreat to move back to open the gas discharge hole (10).

Therefore, the gas stored under reduced pressure in the decompression chamber 7 is ejected through the gas discharge hole 10 opened by the retraction operation of the valve body 15, and the ejected gas is discharged from the outlet part 3 and the connecting pipe 6. It is delivered to the combustor to be burned in the low-pressure butane can combustion apparatus bar, in the present design, the high pressure Elphage gas is passed through the decompression device to reduce the pressure level of the butane can to blow the combustion of the Elphage gas Accordingly, even if the butane can combustion mechanism is used as it is, there is no fear of damage or failure of the combustion mechanism due to the pressure difference of these gases and the possibility of safety accident.

In addition, the valve body 15 which has been retracted and operated by the forward operation of the piston 19 always opens the gas discharge hole 10 of the valve groove 7a by the pressing force of the piston 19 while the gas is burned. The piston 19 in the piston chamber 8 is maintained in the advanced state by the reaction force of the spring 18 provided backward.

On the other hand, in the present invention, the repulsive force of the spring 18 elastically installing the piston 19 in the piston chamber 8 is compared with the spring 14 elastically supporting the valve body 15 in the pressure reduction chamber 7. It is preferable to restrain the valve body 15 from moving forward by the stopping force of the piston 19 even by the reaction force of the spring 14 when the gas is burned, so as not to block the gas discharge hole 10.

Meanwhile, air is sucked into the space between the piston 19 and the screw cap 17 in the piston chamber 8 in which the piston 19 is moved forward through the vent hole 17a formed in the screw cap 17. The valve body 15 which is retracted and operated in the recess 7a is stably moved and operated by the rim 15a inserted into the through hole 4a of the partition 4.

In this state, when the use of the combustor is completed and the valve installed in the combustor is shut off, the combustion movement of the gas through the connecting pipe 6 is stopped. At this time, the connecting pipe 6 is discharged from the pressure reducing chamber 7. Since the gas is discharged to some point through the gas discharge hole 10, the stationary gas in the outlet portion 3 or the connecting pipe 6 is returned to the decompression chamber 7 through the gas discharge hole 10 having a high ejection pressure. As the inflow is prevented, it is eventually flowed back into the piston chamber 8 through the gas backflow hole 11 formed by the partition wall between the outlet portion 3 and the piston chamber 8.

Accordingly, the piston 19, which has been moved forward by the pressure of the gas flowing back into the piston chamber 8, is forced to retreat, and the valve body 15 which is forcibly prevented from moving in accordance with the retraction movement of the piston 19. Is moved forward by the reaction force of the spring 14 to block the gas outlet hole 10 of the valve groove 7a as shown in Figure 1 and at the same time as the through hole 4a is also blocked by the packing 15b The gas blowing in the decompression chamber 7 is reliably cut off, and the piston 19 is retracted until the compressed gas is discharged to the outside through the gas backflow hole 11 again by the gas compression force remaining therein. The state is maintained.

On the other hand, the O-ring 19a provided on the outer circumferential surface of the piston 19 forcibly retracted by the countercurrent gas enables to maintain the airtightness of the gas flowed back into the piston chamber 8, and with the retraction of the piston 19, the screw cap Air filled with the space between the (17) is to be discharged to the outside through the vent hole (17a) formed by the screw cap 17 can be made to move backwards easily.

As described above, according to the present invention, even though the butane can combustion apparatuses are burned by using the high pressure Elgin gas, the butane can combustion apparatuses may be damaged or broken due to the pressure difference, and the safety accident may be caused by the discharge of the pressure gas under a predetermined pressure. It can be safely used without fear of occurrence, especially by inducing the use of LLP gas, which can significantly reduce the use of butane cans, which are more expensive and risk of explosion due to residual amount, and also reduce the damage of environmental pollution caused by butane cans. It can have various effects such as being able to.
