V. Description of the invention (1) [Technical field to which the invention belongs] and the gas pilot burner The present invention relates to a fuel discharge device for a gas pilot burner. [Background Art] In a liquid-filled, ignition valve filled with liquid gas, the lower end of the gas introduction valve is passed through the filter valve through the fuel opening and gas is introduced at the same time, and the temperature of the gas is greatly changed to make the flame overflame. Too small gas ignition flame length adjustment device, but in order to adjust the fire to ignite the newly purchased ignition gas state gas control and control the gas fuel burner, when it is opened, it is gasified with wool, and the nozzle is released to act When the relationship between ignition and combustion is changed due to changes in fuel use, the degree of breadth is long and large. The “easy flameout device” is an ignition device that must be appropriate in order to be the user you like. The gas firing operation control rod of the main body discharge device is discharged from the fuel, and the gasification is discharged to the air device to discharge the component. The liquid gas is dangerous after passing through the filter. The problem is that the user can match the length of the flower to the length of the season, which is equivalent or has not paid attention to the excessive length. When it is widely used, when it is set in the gas fuel sucked by the combustion tank, the fuel emits saturated steam gas, and the gas burner gasifies the gas on the ground, and the temperature is the same when used. inconvenient. When the temperature becomes larger, the flame is discharged and used for the fuel tank. The liquid fuel discharged from the nozzle is to reduce the temperature of the fire section and the length of the fire section when the amount of liquid increases and decreases due to the pressure from the above-mentioned pressure system and the nozzle of the valve. Without danger.

The description of the effect of the structure of the transition device 25 and the effect of the ring 33 is as follows: there is a structure. In the past, it is considered that the liquid used will not swell or deteriorate: it is appropriate. ... It is considered to be immersed in liquid fuels-mentioning that the volumetric swelling rate written in the conventional gas burner used is less than 2%. < Ignition filter I ::::: Yes, the swelling rate of the filter is higher than that of the conventional gas _ filter, which has a higher swelling rate. It can make ::: J the filter used in the present invention is processed into butane immersion in butane. The components of the device are in a normal state at 23 degrees Celsius, and after the inch is compared, before and after Swelling

The rate of 542888 is above 10% and below 80%, and more preferably above 30% and below 70%. The reason for using normal butane as a reference is as described above. The dispenser is composed of a foamed urethane foamed urethane foam bed made of a material having the above-mentioned swelling ratio, and other porous materials such as foamed resin beads, non-woven fabrics, woven fabrics, and microparticle assemblies. As mentioned above, a material having a high swelling ratio has its own shellfish. The present invention uses this property to keep the length of the flame to a certain length. The swelling ratio varies with temperature. The basic principle of the present invention will be explained as follows according to Figs. 3, 4 and 5 according to Figs.

In the picture, 25a is the filter 25, which is made up of the corpse and the subordinates, and 25b is the solid part made of resin material ... The hollow part formed by ^, νο, ^ ^ ^ ^ Body part only. The fuel system flows through the cavity 4 knife 25a, and changes as the pressure decreases. Fig. 3 shows the temperature at a temperature close to room temperature, and the gas flow through the filter is set to a degree of saturated vapor pressure. ^ The swelling ratio of 4 is moderate. 3 The temperature becomes higher than room temperature.

At the same time, the liquid acting on the upstream side of the filter is not shown in the figure. : It is raised to pH, however, the filter swelling rate is also saturated, and the saturated portion of the air pressure is reduced. The hollow portion 25a of the passage is narrowed, suppressing the tile relationship, becoming a fuel, and maintaining the gas flow rate Q at room temperature. When the temperature in the machine increases, and the junction temperature becomes lower than the room temperature TL, if the saturated vapor pressure of the liquid fuel on the upstream side of the device does not affect the relationship between the% filtration rate and the decrease in the filtered state, it will decrease To PL 'However the hollow part of the M 枓 path:

Description of the invention (6) The gas flow rate will not be reduced due to its expansion, and its 本 ^, B this evening ΤΓ 4 〇 Result 'At this time, the gas flow Q of the palace, w day guards can also be maintained. To achieve automatic adjustment of gas flow from t to / 皿, consider _, 叩, ^ y +, the swelling umbrella corresponding to the filter, and must set the porosity of the filter appropriately through experiments, etc. 1 sheep filter The preferred bulk density of the device is-generally in the range of 0 / ~ 2g / c degrees, and more preferably in the range of 0.2 ~ 1.2g / cm3. Zhi Yun If you want to obtain the proper flame length in normal use, the thickness of the filter should be about 30_, preferably 5_. The push # is 0.6 or more, and

When polyurethane foam is used as the material, for example, a polyurethane foam having a volume of 0.02 to 0.08 g / Cm3 is compressed to a bulk density of 0.2 to 1.2 g / cm3 and a thickness of 1 to Use the desired shape of the 5 coffee sheet. ^ Wind As a result of using a filter having a high bulk swelling ratio as described above and the correct bulk density corresponding thereto, the effect of suppressing & ^ flame length change in the desired temperature range can be obtained.

Fig. 6 is a graph showing the comparison of the 'flame length / temperature characteristics' of the gas igniter of the present embodiment and the conventional gas igniter. As can be seen from the figure, the flame length of the conventional gas igniter increases greatly with increasing temperature, but in contrast, the gas igniter of this embodiment has a wide temperature range of 10 to 60 degrees Celsius. Those within the range are slightly-definite. Next, the function of the 0 ring 33 will be described. The provision of the 0 ring 33 prevents the vaporized fuel 5 b in the fuel tank 1 a from entering the inside of the filter 25 through the gap between the capillary holder 29 and the inner surface of the body 1.

If it is full of excessive changes, the capillary filter system is prevalent. At the same time, the temperature is not set from the inside of the filter because the temperature is not set. Q + + tears 25% 33, gasification fuel 5b enters the filter 25, resulting in Inside. As a result, the flame becomes unstable and the length of the right flame varies greatly due to temperature π. If there is no 〇 00 〇 03 k, when the valve is opened, the gas inside the filter 25 is gas ># „^ < rolling relationship, the temperature is reduced, the filter part and the contact part & ^ ^ The difference between the saturated vapor pressure of the knife meal, and therefore, a compression force is generated, > Ran Zhe 'The compression force is related to the stabilization of the temperature as the temperature increases, but it does not help. The O ring 3 3

= ,: Inside the remaining h 1 a there is a higher vapor pressure and heat energy supplied to the passing part, but the relationship between the cooling and compression of the filter, and the flame length is greatly changed. It is a characteristic diagram showing the effect of the ring 33 when a conventional filter is not used. It can be understood from π in Fig. 4 that the conventional filter having a low volume swelling ratio has an effect of preventing the variation of the flame length due to a temperature change due to the ○ ring 33. Next, the second embodiment shown in FIG. 8 is explained as follows. In this case, a sealing member 4 with a quadrangular cross-section is used instead of the aforementioned zero ring 33.

It is clear that the sealing member 41 having this shape can exhibit the same effects as those of the first embodiment. Next, referring to Fig. 9, a third embodiment of the present invention will be described as follows.
