In another embodiment, the gas component is a gas switch. The technical content and other objects and features of the present invention can be fully understood by referring to the following detailed description of the drawings. [Embodiment] ...in the ", the axial internal shape of a thermal gas valve 10 is shown, the second figure shows the radial internal shape, and the third figure is the component decomposition of the element. Technical content. The thermal gas valve 1A includes a gas member 20, and in the first embodiment of the first embodiment, the gas member 20 is an official joint having a gas passage 21 for receiving - a valve seat 22 is formed inside the gas passage 21; a gas pipe, a gas appliance, and a gas timing interrupting device are formed at the inlet of the gas passage 21 and the outer periphery of the outlet side. Or the connecting portions 23 and 24 of the gas switch or the like. It should be noted that the type of the connecting portions 23 and 24 may be a rubber nozzle, a quick joint, a flange joint or a thread as shown in the drawing, which depends on the installation target of the thermal gas burner, _ The examples are intended to be illustrative and illustrative and are not intended to be limited to any of the embodiments. The sixth figure shows the plane in which the gas valve is connected to its mounting object 70. The valve assembly 30 is mounted in the gas passage 21 behind the valve seat 22 to open and close the gas passage 21. The valve assembly 3〇 includes a bracket 4〇, and the center portion 41 has a central portion 41. At the three equal positions of the outer circumference of the central portion 41, a wing piece 42 is respectively provided, and a circular diameter formed by the wing piece 42 is slightly larger than The inner diameter of the M305316 gas passage 21 is such that an interference fit is created between the two, and the bracket 40 is fixed in the gas passage 21. The bracket center portion 41 includes a shaft hole 43 that penetrates the center portion 41 in the axial direction to support axial sliding of a valve body 50. Additionally, one of the bracket flaps 42 (preferably the underlying flaps) has a receiving aperture 44 that communicates with the axle bore 43 for mounting a steel ball 60, a rod member 61 and a spindle 62. The steel ball 60, the rod member 61 and the spindle 62 are sequentially loaded into the receiving hole 44 of the bracket 40 from the inside to the outside. Wherein, the steel ball 60 and the receiving hole 44 are matched with a clearance. The outer diameter of the rod member 61 is smaller than the inner diameter of the receiving hole 44 to define a gap having an annular shape therebetween, so that the spindle 62 can be raised after the melting of the rod member 61 due to the sinking of the rod member 61. (fourth picture). The spindle 62 is formed into a circular or cylindrical shape by a fusible alloy having a melting point of about 80 to 100 ° C, and is inserted into the receiving hole 44 by an interference fit technique to prevent the steel ball 61 and the rod 62 from loosening. And falling off, and at the same time, the outer end of the spindle 62 is preferably in contact with the hole wall of the gas passage 21, so that the spindle 62 can be melted immediately when the temperature of the gas member 20 rises to a predetermined value, so that the hot gas Valve 10 produces a shorter reaction time. In the embodiment of the drawings, the steel member 60 is supported by a rod member 61 supported on the spindle 62, but the rod member 61 can also be omitted, and the steel ball 60 can be directly held by the spindle 62. Of course, the steel ball 60 may be integrally formed with the rod member 61, or a head portion that can be engaged with the annular groove 53 to be described later is directly formed at the upper end of the rod member 61, instead of the function of the steel ball 60, the details of which will be described later. For the time being. The valve body 50 constitutes a part of the valve assembly 30, and includes a rod shaft 51, and a valve portion 52 formed at the front end of the rod shaft 51. The rod shaft 51 can slide 8 M305316 freely through the shaft hole 43 of the bracket 40. And having an annular groove 53 that cooperates with the steel ball 60 to maintain the valve body 50 in a position where its valve portion 52 is away from the valve seat 22 (i.e., the valve opening position). There is also a pressure spring 63 between the central portion 41 of the bracket 40 and the valve portion 52 of the valve body 5, which is also a dam portion of the valve assembly 3, and is sleeved on the outer circumference of the shaft 51 of the valve body 50. The front end thereof supports the end portion of the valve portion 52' of the valve body 50 to be supported by the center portion 41 of the bracket 40. Once the valve body 50 is made of steel beads

The fourth part of the road is the details of the road. Move ~ its valve body 50 to close the gas pass. There are other variations that can be made in this creation. Anyone who knows this technology can do the above-mentioned changes or modifications. Therefore, the same parts as those in the embodiment of the present invention are denoted by the same reference numerals, and the description of the embodiment shown in the first figure also applies to the following embodiments, and will not be described again. The fifth figure shows a thermal interrupting valve 1 〇a similar to the second one. The difference between this embodiment and the embodiment shown in the second figure is the number of fins of the stent. In the above embodiment, the number of the fins 42 is three, which are spaced apart from each other by 2 degrees. In the present embodiment, the bracket 40a has two fins 42a spaced apart from each other by 18 degrees, so that the same function can be achieved. In addition, the 'gas member 20 is not limited by the above embodiment, and it can be a gas switch; in other words, the valve assembly 30 can be used in cooperation with a gas switch, so that the gas switch has both heat and reaction. The safety valve, the seventh diagram shows an embodiment in which the valve assembly 30 is incorporated into a gas switch 8A. The gas switch 80 includes a housing 81 having a gas passage 82 formed at a predetermined position in the second portion of the gas passage 82 to accommodate a "opening plug 83" which is cylindrical (or spherical) The valve plug 83 can be rotated by operating a knob 84 to open and close the gas passage 82. The gas passage behind the valve plug 83 is formed and has -_85 _ _ 3 () installed in the gas passage 82 of the valve seat. When the valve assembly 3 is in the non-actuated state = 2: the valve seat 8_path 82 is maintained to allow the gas flow body 501 to be zippered, the magazine 63 can use its restoring force to make the valve creation through the easy-to-sleeve phase. Than 'the effect is positive and obvious. The steel ball is held against the position of the steel ball seat to eliminate the cleaning joint surface and the addition; the welding M305316 can be used in the following conditions: the manufacturing combination in the case of efficiency greatly improves the production efficiency 5 to prevent the misoperation of the material (4). Dry change, so the case can be used without any deviation from the scope of this creation, if it is included in the scope of the article, and it should be used as an example, not to limit the creator.
