[0003] The gas valve is a new type of safety device for gas pipeline engineering. It is used to cut off, connect and adjust the gas in the pipeline. It has good control characteristics and closing and sealing performance. It is suitable for city gas, liquefied petroleum gas, natural gas, oxygen and other gas medium pipelines.

[0004] After searching, it is proposed in a valve lock for a gas valve with patent publication number CN202021452075.0 that "the valve lock for the gas valve can fix the gas transmission pipeline through the cooperation of the first clamping plate, the second clamping plate, the first clamping column, the first fixing groove, and the connecting block, thereby improving the stability of the device. At the same time, it is suitable for gas valves of different specifications, thereby improving the usability of the device. Through the cooperation of the connecting rod, the protective cover, the second fixing groove, and the second clamping column, the valve control handle is protected when the valve control handle is not used, thereby improving the safety of use";

[0005] However, the above solution still has certain shortcomings in actual use. In this solution, two protective covers are gathered together to wrap the control handle at the top of the gas valve to protect it, thereby avoiding the problem of gas leakage in the pipeline caused by accidental collision.

[0006] However, this solution does not provide a self-locking structure for the control handle, which may cause the control handle of the gas valve to slide slightly after a long time, thereby causing gas leakage. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model discloses a gas valve structure for gas, comprising a mounting platform 1, a fixing structure 2 is arranged at the top of the mounting platform 1, a gas valve device 3 is movably connected inside the fixing structure 2; the gas valve device 3 comprises a valve body 301, both the front and rear sides of the valve body 301 are connected to a gas pipeline 310 through a sealing cover 309, a rotating handle 303 is rotatably connected to the top of the valve body 301, a sleeve 304 is fixedly sleeved on the outer side of the rotating handle 303, a limiting plate 305 and a connecting bearing 306 are fixedly sleeved on the outer side of the sleeve 304, a vertical groove 311 is opened on the surface of the sleeve 304, a follower rod 312 is slidably connected to the inner wall of the vertical groove 311, the other end of the follower rod 312 is fixedly connected to the inner ring of the connecting bearing 306, and the outer ring of the connecting bearing 306 is rotatably connected to the connecting dome The top 307, four pillars 308 are fixedly installed at the bottom end of the connecting dome 307, and four square holes are opened at the top of the valve body 301. The bottom ends of the pillars 308 are movably plugged into the inside of the square holes, and the gaps between the four pillars 308 are movably engaged with the two limit plates 305 respectively; by setting the limit plates 305, the connecting dome 307 and the pillars 308, the connecting dome 307 that can be lifted and rotated on the outside of the sleeve 304 can drive the four pillars 308 to lock the position of the two limit plates 305, so that the rotating handle 303 completes the self-locking structure under the restriction of the pillars 308 and the limit plates 305, so that the rotating handle 303 will not rotate by itself in the idle state, thereby avoiding the situation that the control handle of the gas valve may slightly slide after a long time, thereby ensuring the safety of the use of the gas valve.

[0023] Specifically, the fixed structure 2 includes a connecting seat 201, and a contact arc plate 202 is fixedly installed inside the connecting seat 201. The top of the contact arc plate 202 is movably plugged with an overlapping arc plate 203. The side surfaces of the contact arc plate 202 and the side surfaces of the overlapping arc plate 203 are both provided with connecting holes. The contact arc plate 202 and the overlapping arc plate 203 are movably connected through the connecting holes and the connecting pins 204.

[0024] In this embodiment, the gas pipelines 310 at the front and rear ends of the valve body 301 are placed on the contact arc plate 202, and then the overlapping arc plate 203 is plugged into the contact arc plate 202, so that the gas pipeline 310 is clamped between the overlapping arc plate 203 and the contact arc plate 202, and then the connecting pin 204 is inserted into the socket of the contact plate to complete the combined splicing between the overlapping arc plate 203 and the contact arc plate 202, so that the valve body 301 is connected to the mounting platform 1.

[0025] Specifically, a cover 302 is overlapped on the top of the valve body 301 , and the rotating handle 303 is located in a cavity formed between the cover 302 and the valve body 301 .

[0026] In this embodiment, the cover 302 can be used to wrap and protect the outer side of the rotating handle 303, thereby further improving the protection effect.

[0027] When in use, the gas pipelines 310 at the front and rear ends of the valve body 301 are first placed on the contact arc plate 202, and then the overlapping arc plate 203 is plugged into the contact arc plate 202, so that the gas pipeline 310 is clamped between the overlapping arc plate 203 and the contact arc plate 202, and then the connecting pin 204 is inserted into the insertion hole of the contact plate, so that the overlapping arc plate 203 and the contact arc plate 202 are combined and spliced, so that the valve body 301 is connected to the mounting platform 1;

[0028] When the direction of the rotating handle 303 needs to be adjusted, the connecting dome 307 is pulled up in advance, so that the connecting dome 307 drives the follower rod 312 to slide vertically inside the vertical slot 311 through the connecting bearing 306, so that the connecting dome 307 drives the pillar 308 to gradually lift up, so that the pillar 308 gradually moves away from the square hole at the top of the valve body 301, and the connecting state between the pillar 308 and the limit plate 305 is released at this time. Since the rotating handle 303 is released from the locking state of the limit plate 305, the rotating handle 303 can rotate freely at this time, so that the staff can adjust the angle of the rotating handle 303 at this time;

[0029] Since the rotating handle 303 included in the gas valve device 3 usually only needs to be rotated ninety degrees and one hundred and eighty degrees, after the rotating handle 303 is adjusted, the final position of the limit plate 305 will only be parallel to the valve body 301 or intersecting with the valve body 301, and then the connecting dome 307 is pulled down, so that the connecting dome 307 drives the follower rod 312 to slide vertically inside the vertical groove 311 through the connecting bearing 306, so that the connecting dome 307 drives the pillar 308 to gradually descend, and the pillar 308 is inserted into the square hole at the top of the valve body 301 again, so that the four pillars 308 are clamped with the limit plate 305 again, so that the limit plate 305 cannot be rotated at this time, and the rotating handle 303 cannot be rotated at this time, so that the rotating handle 303 is limited, thereby avoiding the rotating handle 303 from rotating by itself in the idle state.

[0030] In summary, the gas valve structure for gas, by setting the limit plate 305, the connecting dome 307 and the pillar 308, utilizes the connecting dome 307 which can be raised and lowered and rotated on the outside of the sleeve 304 to drive the four pillars 308 to lock the position of the two limit plates 305, so that the rotating handle 303 completes the self-locking structure under the restriction of the pillar 308 and the limit plate 305, so that the rotating handle 303 will not rotate by itself in the idle state, thereby avoiding the situation that the control handle of the gas valve may slightly slide after a long time, thereby ensuring the safety of the use of the gas valve.
