Description

M263464 V. Creation description (1) [Technical field to which the new type belongs is an improved structure of a gas safety valve, especially when the gas exceeds the flow rate, a safety ball can be used to close the gas passage within a set range to close the gas passage And prevent a large number of leaks. [Prior technology] The applicant's father obtained a new patent of the Republic of China No. 70241 110 "Watt safety valve device", and found that-^ ^ ^ ^ f ~ is because it is not a type of gas safety valve. watt? It is used on the adjusting cymbal, and its structure includes a pipe head with an inclined section with a safety ball. The narrow pipe head at the upper end of the inclined section is equipped with a buffer spring with a slow spring. When a large amount of gas leaks, large sides of the safety ball are generated. The pressure difference will push the safety ball to block the delivery nozzle to close the gas passage, and the effect of preventing a large amount of gas from being superficial; when the large amount of gas leakage is improved, for example, a hole has been repaired or the pipeline has been connected. … Etc. Although gas supply elements such as gas cylinders may have been shut down and closed, the pressure of gas between the safety ball and the gas supply element will cause the safety ball to remain at the mouth of the delivery pipe, pressing the upper end of the buffer rod Press the head of the cap to push the safety ball under the buffer rod away from the conveying nozzle, so that the passage can be used for the normal circulation of gas; this tile, the safety valve device is mainly used for outdoor stoves, because the safety ball and the nozzle No leak-proof parts are provided. When a large amount of gas leaks due to ^ = f blocking the delivery pipe, it will not continue. However, the gas supply unit will continue to supply gas after Wang Yue has not been shut down. Global and conveyance nozzles pass through small gaps; Also, even if the gas leaking situation has been improved, the supply of 5 gas may have been shut down and gas supply has been stopped, but it will remain in the safety ball and Gas supply between gas will still be safe

Page 4 M263464 V. Creation Instructions (2) The air gap between the ball and the pipe opening is dilute by air, so the device outside the house is not suitable for the stove in the house. The accumulated gas is easy to cause disaster when it is opened. On both sides of the ball, there are caps that close the gas passageway to plug the gas passage, and the buffer rod is lowered to allow the passageway for gas to flow normally. Therefore, the Republic of China No. 872 1461 3 "and No. 90208341" Gas safety is also combined with The structure of the gas regulator uses a valve body with no placement. When a large amount of gas leaks, it will push the safety ball to compress the spring to close the gas passage, and after the leak prevention is improved, although the gas supply state is improved, However, the safety ball is subject to the pressure of gas. As the pressure difference between the two ends of the microballoon between the safety ball and the second channel safety ball and the second channel mouth gradually decreases, the safety ball is elasticized by the spring force. This kind of gas is safe. The valve device is also suitable for the same reasons as above. [Content] Bypass, because this gas can be used outside the house without affecting its safety; however, it is used because Gas is less harmful; moreover, each time the gas supply unit has a large pressure difference, it will also promote the safety ball resistance. 'The user must press the upper end of the buffer rod to push the female globe away from the delivery nozzle to make it inconvenient. The applicant also obtained a new patent for the "safety valve of the new patent case" of the gas safety valve device, and used it to reveal a channel with the same inside diameter of a gas safety valve for a large pressure difference between the spring and the safety ball safety ball. The safety ball stays at the second passage opening and the effect of the tile is' when there is a large amount of gas leakage, such as gas cylinders, it is still in a closed state, and it still stays between the second passage openings. There is no leakage prevention device, so there is a small gap. For the passage of a small amount of gas, so that there is no longer enough force to compress the spring, and to open the gas to return to normal circulation, it is also used for outdoor stoves.

V. Creation description (3) The improved structure of the whole valve of the purpose of the creation 'The body is equipped with a safety ball and a force-limiting spring, which is pressed tightly and pushed away from the leak-proof part by the buffer rod. When the pressure difference between the two passage openings There is a pressure difference value when the gas supply unit is set up in the gas safety unit. Each time the channel is closed, there is a type for manufacturing, which is based on the placement of parts with different inner diameters. It will be known that pressing the cap head can make the channel supply tile with leak-proof parts, that is, blocking the gas valve full valve can also provide the house with the appropriate elastic constant. When it can be pushed and opened safely, the safety effect can solve the above shortcomings. Install the channel for the gas leakage channel to be closed and pressed. It is normal to prevent the spring ball of the inner stove from being lost when the ball leaves the ball. When the non-house stove is equipped with a buffer, a spring leak is provided to achieve buffer circulation. . It is used to stop gas safely; the top of the gas spring spring of this bomb is often ideal. A defense will push the anti-leakage rod down due to the leakage of the two sides of the safety ball. Furthermore, the spring is not in the way, because of the push, the gas is not safe. The function of buffering missing parts and the pressure of a safety ball will make the safety ball global and larger. Therefore, because the passage has reached a larger level, when the gas will make the gas to make the aforementioned and other purposes, features and advantages of this creation more Obviously, it is understood that "the preferred embodiment of the present invention is enumerated below, and is accompanied by the accompanying drawings" for detailed description. [Embodiment] As shown in the first and second figures, the modified structure of the gas safety valve of the present invention is based on a body 1 provided with a seat hole 10 having a threaded portion 11 0, and 5 in the body 1. There are a first channel 11, a first channel 12 and a third j channel 13 with different inner diameters. The third channel 13 is an air inlet end, the first channel 11 is an air outlet end, and the inner diameter of the first channel 11 is slightly smaller than that of the second channel. 12, one end of the first channel 11 communicates with the first channel 12, and the first channel u and the second channel 12 are connected to form a M263464. V. Creation Instructions (4) The inner diameter of the second channel 12 is slightly smaller than the third channel 13 The second and third channels 13 communicate with each other at the ends, the second channel u and the third channel 13 r ^ ί ^ large stop portion 15, when the gas safety valve of this creation is combined: when the gas outlet end of the device, the first channel 11 is another One end is connected to the stove ^ 'The second channel 13 is connected to the gas outlet of the gas regulator. When the gas safety valve of the gas regulator is combined with the gas inlet of the gas regulator, the other end of the first channel 11 is adjusted to the gas. The inlet end of H is connected, and the third channel ::: end J gas supply element of the gas outlet port, so the gas supply element The gas of the response can follow the third channel 13, the second channel 12, and the first channel " to the threaded portion 11 of the manhole ^ hole 10, for a threaded portion outside the bottom end of the pipe 2 2 screw: 2 is integrated with the body! There is a narrow P-benefit hole 21 with a smaller inner diameter than the official seat 2 at the appropriate place in the tube seat 2. The narrow p-benefit hole 21 is fixed below the leak-proof rubber ring 23 'leak-proof The inner diameter of the rubber ring 23 is the same as the outer diameter of the buffer rod. 嗣, the narrow follow hole 2 丨 and the leak-proof rubber ring 23 allow a buffer rod 22 to penetrate and move up and down J to maintain the airtight and leakproof effect. ; In order to make the buffer rod return to its original position after pressing down, the buffer rod 22 penetrates with a __ force.
