Abstract

PURPOSE:To stabilize combustion as well as ensure to put it out by a structure wherein a valve, which controls gas flow in response to the change of gas pressure, and a valve to close and open the outlet of said valve are provided between a liquefied petroleum gas tank and a torch mixer. CONSTITUTION:A liquefied petroleum gas tank 11 is connected through a first and a second valves 12 and 13 to a primary vaporizing chamber 14 and then connected through a filter 15 and a conduit 16 to a secondary vaporizing chamber 17. The secondary vaporizing chamber 17 is formed at the inceptive end of the torch mixer 18, at the other end of which a nozzle 21 is provided. The first valve 12 controls gas flow rate by controlling a male screw 23 in order to change the contact pressure between an O-ring 24 and a disc 25. Furthermore, the second valve 13 controls gas flow rate by opening and closing the outlet 26 of the first valve 12 by means of a needle 31 equipped with a turning knob. Owing to the structure as described above, the abrupt change of gas pressure is controlled by the first valve 12 in order to stabilize flame, and when out of use, the second valve 13 quickly shuts-off the gas supply.

In actual use, it is necessary to adjust the size of the flame depending on the object. Therefore, in the above proposal, a needle valve (2) is installed in the micro gap 11 (5), and the size of the effective area of the micro gap @ (5) is changed by opening and closing the needle valve, thereby reducing the amount of gas released. It is meant to be controlled.

-2- However, if the effective area of the minute gap (5) is suddenly increased by turning the needle rod (8) when enlarging the flame, the supply power of the liquefied petroleum gas (7) in the gas tank (1) will decrease. suddenly increases in size, and a large amount of liquefied petroleum gas (7) flows into the vaporization chamber (3) in its liquid state, and before it is completely vaporized, gas is ejected from the torch crater (4), creating a flame accompanied by gas mist. . This is dangerous. Not only that, but
Even if an attempt is made to extinguish the gas, it will not be possible to do so until the liquid gas accumulated in the vaporization chamber (3) is completely combusted.

In addition, as the temperature and internal pressure increase sequentially from the vaporization chamber (3) to the gas tank (1) due to heat conduction after ignition, the gas pressure in the vaporization chamber (3) and the gas pressure in the gas tank (1) increase. The balance was unstable, and it took at least 30 seconds after ignition for the balance to stabilize, which required work to be done, which was a waste of fuel and time.
