New description: [New technical field] This case relates to an on-off valve that can control high-pressure gas, such as liquefied petroleum gas cylinders. 0 is used to refer to the heat source used in the [Prior Art] test 8% of the week. That is to say, cooking is the case. Most of the gas is mostly gas, especially in the 2nd and 2nd courts. It is not the official supply of pipelines or barrels with steel cylinders. It is also often used as a heat source for water heaters. Spears, Yuyi and the significant lack of gas use, lies in the safety of the basin, such as gas stoves or water heaters are not complete, resulting in - oxygen cookware column = unfortunately _ see the face. Ploughing, on the subject of f, ^ Ruo: 1 shut the valve abnormal 'and lead to the leakage 'If you run into another: Miao explosion', so some people say that the barreled gas is "untimed fried shellfish" open / gasification know The on-off valve is visible in the top opening of the valve body. Port, and =< Another screw (filled nut) is screwed on the top of the valve body to open the screw of the additional control rod, and the top of the control rod The two poles of the control rod and the screw cover are right; the mouth is a left thread, and the flow path is opened and closed between the *. When the switch cover is rotated by the control rod; the rotation of the handle is forced to make the screw gas The top of the body is open at the top of the spray valve, and the top opening of the body is loose, which makes the high genus dangerous. Therefore, it is known that it is used for phenotype, and when it hits the flame on the right side, the safety of the gas explosion is enhanced and improved: = body, _ is The new content of the switch valve of the gas steel ship], - The purpose is to provide a kind of opening for the high-speed gas steel, the axial movement of the 3 plugs, the upper stop direction = to >, - stop The member 'brings the control rod to avoid the danger that the lever will be pressed against the stop member by the flange portion of the 31 hoe. In order to avoid the high-pressure gas squirting, it is possible to make high-level mining. (4) Technical bribery supply - the kind of the outer wall diameter below the opening of the body of the body is at least the handle of the valve body at the bottom of the rod, and the top of the it is connected to the skirt. One exposed to the air-forming effect of the main body - less than the inner wall of the main channel, the piece is inserted and fixed in the positioning groove, and the handle is fixed, so that the control rod drives the plug to cover at the bottom of the flange portion of the = The valve port is used to cut off the main channel and: =5; the flange portion of the head is used to loosen the stop member, so that the handle is not continued. The second step is to further reveal the specific technical content of the case. The opening of the gas cylinder _ stereo decomposition order, for the opening of the gas valve cylinder of the μ gas cylinder ^ ^ ^ two sections taken along the line A_A and the line Β · i i Figure 3 and Figure 4 is Figure 2 [ Embodiments As shown in FIGS. 1 to 4, basically, a cable such as a gas dam, a pressurized gas 'a stop member 3' is formed. 2 and at least, the valve body is made of metal, such as brass. Forged manifold, the M404309 part has a class-like mainstream road 11, which is about The valve port H position of the middle section is radially connected to a filling port 12 for passing high pressure liquid gas through the main channel 11 and into a container, such as a steel ship, and the filling port 12 is also The opening for the high-pressure gas output after gasification in the cylinder. The valve body has a valve base at the bottom of the valve body. The 卩13 has an external thread 131 at its periphery for screwing to the cylinder. 11 is provided with an opening 14 at the top, and an inner thread _ 141 is provided on the inner wall for the installation of the control device 2, thereby controlling the shut-off of the high-pressure gas. Further, the valve port 111 to the valve base 13 of the main flow channel 11 Between the other diameters g, a mouthpiece 15 is connected, and the student's mouth 15 is provided with a conventional pressure-pressure safety valve 16. When the pressure inside the cylinder is greater than 24 kg/cm2, the safety valve 16 is opened, so that Nanet can be opened. Excessive pressure release to ensure safe use of the cylinder, but the manner in which the safety valve 16 is actuated is a well-known skill and will not be described here. The control device 2 is composed of a - control lever 21, a plug 22 and a handle 23. The plug 22 is at the bottom of the lever 21 and the handle 23 is mounted on the top of the lever 21. The outer edge of the control rod 21 is provided with an external thread 211 for screwing into the internal thread 141 of the inner wall of the top opening 14 of the main flow channel 11. Therefore, when the handle 23 is rotated, the rod 21 can drive the plug head 22 to move axially in the main flow channel, and at least one of the flange portions 221 of the lower portion of the plug 2 is radially disposed. The airtight action formed by the inner ring 222 and the inner wall of the main flow channel prevents the high pressure gas from being leaked from the main flow port and the top opening 14. Further, the bottom surface groove 223 of the flange portion 221 of the plug head 22 is tightly sealed. 224. When the rotating handle 23' is in the closed state, the sealing gasket 224 shields the valve port to disconnect the main passage μ from the filling port, so that the supply of the high pressure gas in the cylinder is cut off, and Cannot be output by the filling port 12. In particular, in order to provide the combination of the control rod 21 and the plug 22, the bottom of the control rod 21 = the radially open-inverted-shaped groove 212, and the top of the plug 22 corresponds to the top SETTING - the rib 225 is inserted into the slot 212 to 'make the two, ', and the body' and the plug 22 can be displaced synchronously. The present case is different from the conventional one. The outer wall diameter of the opening 14 of the valve body 1 is 5 M404309 = 2; the positioning groove 17 of the track 11 is as shown in FIG. 1 and FIG. The outer wall of the μ side is parallel-opened—the pair of slots 7 are positioned so as to be inserted into a stop member 3, respectively, and the time is set to be off, the second is determined: the time is generated, ^ convex = 'the pair of stop members 3 Between the control rod 21 and the convex U 221 of the plug head 22, and as the upper portion of the flange portion 221 =, when the switching valve is in the open state, the sealing port 224 moves into the flow port 1 and forms a communication with the filling port 12. Therefore, the cylinder 2 is supplied with a 3 output and the top surface of the flange portion 221 abuts against the pair of stopper members, and the control rod 21 is continuously rotated by the main, Λ 11 ΐ method, so that the control rod 21 does not become a shackle. Take off, so as to avoid the possibility of high-pressure gas ejection. Therefore, through the implementation of this case, the effect of the gain is that the interference of the open convex portion f can prevent the control rod from causing the flow channel to be deflated and removed. Still pressure gas, such as gas squirting, may cause blasting slaves. In addition, the flange part of the plug head is designed with two 〇-shaped rings, which can guarantee the double protection of the 翻--------- g σ气进 The person disclosed in this case is the __ kind of the preferred embodiment, which is derived from the technical idea of the case and is familiar with the skill == repairing the case.
