ガス遮断装置の出現が望まれている。 Conventionally, as a gas cutoff device installed at an appropriate location in a flammable gas supply route to prevent backfire or detonation, there is a gas safety device as previously disclosed by the applicant in Japanese Patent Application No. 13326/1983. In these gas safety devices, the elastic biasing force or blocking force of the gas cutoff valve is generally adjusted so that the gas cutoff valve operates when the pressure exceeds a certain level. In such a gas shutoff device, if flashback occurs at a pressure below the set pressure, the shutoff valve will not operate and a combustion state will occur in the vicinity of the flame extinguishing material.
There is a phenomenon in which the temperature of the flame extinguishing material rises due to the heating caused by this combustion, which heats the gas on the supply side of the gas supply path, causing it to ignite. Conventional gas cutoff devices that operate above a certain pressure are not suitable for such phenomena, so we developed a gas cutoff device that can appropriately shut off gas even when ignition occurs below a certain pressure. It is hoped that the emergence of

のである。 In view of the problems with conventional gas cutoff devices, the present invention aims to provide a device that operates at a constant temperature, and includes a gas cutoff valve that is always energized toward the gas supply path. A chamber communicating with the gas supply path is provided, and a temporary locking means that engages with the gas cutoff valve is disposed in the chamber, and one or both of the engaging portions of the gas cutoff valve and the temporary locking means are disposed in the chamber. A gas cutoff device having a temperature-sensitive gas cutoff valve is completed by forming the adhesive part of the entire part or the part constituting the engaging part with a material that can be softened or melted at a temperature below the ignition temperature of the combustible gas. This is what I did.

度とするのが適当であると知見された。 In such a known gas cutoff device, the present invention provides a gas cutoff valve 16 associated with the temporary locking means 15 represented by the stopper or the like, that is, a locking of the outlet valve 5 in the illustrated example. A part or all of one or both of the engaging parts 17 or the mounting part of the part constituting the engaging part is made of a fusible material 18 that can be softened or melted at a temperature below the ignition temperature of the combustible gas. When a flashback occurs from the exit direction, that is, from the right side of the gas supply path 3 in the figure, under a condition where the pressure is lower than the set pressure, the temporary locking means 15 is not activated due to the flashback and reaches the flame extinguishing material 7. Inside the pipe on the outlet side and inside the gas cutoff device, especially inside the outlet side of the flame-extinguishing material 7 and its surroundings, and the gas introduction pipe 1
The combustible gas burns in the chamber 21 through the chamber 21, raising the internal temperature thereof. Therefore, when the engaging portion 17 is directly heated in the chamber 21 and the inside and surroundings of the outlet of the flame-extinguishing material 7 are heated, and the temperature of the engaging portion 17 exceeds its softening or melting temperature, As the melt material 18 softens or melts, the engagement between the gas cutoff valve 16 and the temporary locking means 15 is released, that is, in this case, the engaging portion 17 of the temporary locking means 15 disappears or the gas When a part of the cutoff valve 16 disengages, the mutual engagement relationship is lost, and the gas cutoff valve 16 cuts off its supply outlet side due to the elastic force applied from the rear, and the gas cutoff valve 16 closes its supply outlet side. This combustion state is stopped within the space formed by the flame retardant 16 and the flame extinguishing material 7, thereby preventing the combustion from spreading to the supply side.
Here, forming the adhesive part of a part or all of one or both of the gas cutoff valve 16 and the engaging part 17 of the temporary locking means 15, or the part constituting the engaging part, using the fusible material 18 means that, for example, Temporary locking means 1
The stopper 11 as 5 is formed of a metal body similarly to the conventional gas cutoff device, and the shaft body 19 that constitutes the main body of the gas cutoff valve 16 is separated from the external fitting part 20.
The outer fitting portion 20 can be fitted into the rear part of the shaft body 19 at a certain interval, and the stopper 11 of the temporary locking means 15 may be configured such that the outer fitting portion 20 can be fitted into the rear part of the shaft body 19 at a certain interval and adhered to each other through the fusible material 18 during the interval. The upper main body portion of the stopper 11 and the portion to be fitted into the groove 10 are cut at a suitable position in the lower part, preferably at a position higher than the depth of the groove 10 of the gas cutoff valve 16, and these are attached with a fusible material. Alternatively, the entire area behind the groove 10 of the gas cutoff valve 16 may be made of fusible material 18, or the entire stopper 11 as the temporary locking means 15 may be used. A gas cutoff valve made of a welding material 18, etc., and a gas cutoff valve with a slit in the direction of the shaft, a notch for engagement in the middle of the slit, and a cutout in the body into which the gas cutoff valve is inserted, and introduced into the slit. In addition, it refers to a locking member (see Japanese Patent Application No. 53-46795) that can be engaged with a notch and is formed of a fusible material, and is encompassed by various of the above expressions other than these embodiments shown in the present invention. These specific means do not exclude the application of the present invention in any way, and may be adopted as appropriate. Also, if the temperature on the outlet side that can be softened or melted at a temperature below the ignition temperature of the combustible gas, that is, the temperature on the outlet side from the inside of the flame-extinguishing material, exceeds the ignition temperature of the supply side gas, it is natural that the supply side gas Therefore, it is necessary that the gas on the supply side, that is, the flammable gas used in the gas feed line, be able to soften or melt at a temperature below the ignition temperature, and preferably the flammable gas A material whose lower limit is lower than the ignition temperature of the combustible gas and which operates at a temperature higher than the summer outside temperature, more preferably a fusible material whose softening or melting temperature is 1/2 of the ignition temperature of the combustible gas and which is inside the interior of a state left outdoors in the summer. According to tests conducted by the present inventors, the average internal temperature was 53°C, but experiments have shown that it is appropriate to set the minimum melting temperature to about 80°C.

維持するものである。 As described above, the gas cutoff device according to the present invention includes:
A gas cutoff valve associated with a temporary locking means is provided in a gas cutoff device provided at a suitable location in the gas supply path, and a chamber 21 is provided which communicates with the gas supply path 3 via a gas introduction pipe 13, A part or all of one or both of the engaging portions of the gas cutoff valve and the temporary locking means, or the mounting portion of the portion constituting the engaging portion, may be made of a material that can be softened or melted at a temperature below the ignition temperature of the combustible gas. Since it is made of a melted material, the temperature of the engaging part 17 is directly heated in the chamber 21 due to backfire, and it is also heated at the exit of the flame extinguishing material 7 and around it, so the temperature rises immediately. When the temperature reaches or exceeds the softening temperature of the fusible material, the fusible material softens or melts, and a part of the temporary locking means is bent or removed, or a part of the gas cutoff valve comes off. As a result, the mutual engagement between the temporary locking means and the gas cutoff valve is released, and the gas supply path is cut off by the elastic force of the gas cutoff valve, which is energized from behind. Even if flashback occurs when the pressure is below the set pressure of the gas cutoff device,
This backfire is shut off by the temperature sensing means at the position of the gas cutoff device provided at an appropriate location in the gas supply path, thereby maintaining safety.
