Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A fully automatic gas safety valve device includes a valve pipe 1, and an automatic opening and closing mechanism 2 is provided at the top of the valve pipe 1 to realize automatic and rapid response closure of the valve pipe. The automatic opening and closing mechanism 2 includes:

[0028] The housing unit 21 is disposed on the top of the valve tube 1, and includes a housing 212 fixedly installed on the top of the valve tube 1;

[0029] The opening and closing unit 22 is located inside the housing unit 21. It includes a lifting rod 221 that slides through the valve pipe 1 and the fixed plate 211. The lifting rod 221 has a threaded post 225 rotatably installed inside. A sleeve 226 is fixedly installed on the top of the threaded post 225. A worm gear 227 is fixedly installed on the surface of the sleeve 226. The pressure sensor 3 detects the internal pressure of the valve pipe 1 to determine the pipeline leakage. The valve plate 222 is driven by the drive unit 23 to close the valve pipe 1.

[0030] The drive unit 23 is located inside the housing unit 21 and is used to drive the opening and closing unit 22.

[0031] In this embodiment, a rubber ring 223 is fitted around the outside of the valve plate 222, and the rubber ring 223 contacts the inner wall of the vertical pipe of the valve pipe 1 to achieve gas isolation inside the valve pipe 1.

[0032] Model 6 is MIK-P3000. It judges the internal pressure of valve pipe 1. When the pressure exceeds the set standard, the drive unit 23 drives the worm gear 227 to rotate the sleeve 226. The sleeve 226 drives the threaded column 225, which in turn drives the lifting rod 221 to descend. When the lifting rod 221 descends, the limit block 2210 slides inside the limit groove 224 to limit the movement of the lifting rod 221. The lifting rod 221 drives the valve plate 222 and the rubber ring 223 to insert into the vertical pipe of valve pipe 1, thereby realizing the automatic opening and closing of the valve to release or cut off the gas, effectively protecting the safety of gas equipment and personnel.

[0033] In this embodiment, a fixing ring 228 is fixedly installed at the bottom of the inner cavity of the housing 212, a limiting block 2210 is fixedly installed on the inner side of the fixing ring 228, and a rubber pad 229 is installed on the fixing ring 228 and the bottom of the inner cavity of the housing 212. A limiting groove 224 is opened on the side of the lifting rod 221, and the limiting block 2210 slides inside the limiting groove 224 to limit the movement of the lifting rod 221.

[0034] When the lifting rod 221 moves up and down, the limiting block 2210 slides inside the limiting groove 224 to limit the movement of the lifting rod 221.

[0035] In this embodiment, a fixing plate 211 is fixedly installed on the front and rear sides of the valve pipe 1, a housing 212 is fixedly installed on the top of the fixing plate 211, a top cover 214 is fixedly installed on the top of the housing 212, a rubber pad 213 is fixedly installed between the top cover 214 and the housing 212, and a control panel 215 is fixedly installed on the top of the top cover 214.

[0036] The top cover 214 is fixedly installed on the top of the housing 212 by bolts, thereby facilitating the inspection and maintenance of the interior of the housing 212.

[0037] In this embodiment, the drive unit 23 includes a fixed frame 231 at the bottom of the inner cavity of the housing 212. A rotating cylinder 232 is rotatably mounted inside the fixed frame 231, and a worm gear 233 is fixedly mounted on the surface of the rotating cylinder 232. A mounting frame 239 is fixedly mounted at the bottom of the inner cavity of the housing 212, and a motor 2310 is fixedly mounted on one side of the mounting frame 239. The output end of the motor 2310 passes through the mounting frame 239 and is fixedly mounted with a connecting cylinder 2311. The worm gear 233 is meshed with a worm wheel 227.

[0038] The motor 2310 is model KV3SF-8521F-WR. It is electrically connected to an external power source and can be started and stopped by a human-operated control panel. When the motor 2310 runs, it drives the connecting cylinder 2311 to rotate. The connecting cylinder 2311 drives the rotating cylinder 232 and the worm gear 233 to rotate. The worm gear 233 drives the worm wheel 227 to rotate, which in turn causes the sleeve 226 to rotate.

[0039] In this embodiment, the front side of the rotating drum 232 penetrates the front plate of the housing 212. A sliding locking pin 235 is slidably installed inside the rotating drum 232. The locking teeth of the sliding locking pin 235 engage with the sliding locking hole 234 and the internal locking groove of the connecting cylinder 2311 to drive the rotating drum 232 to rotate. One end of the sliding locking pin 235 is slidably inserted into the connecting cylinder 2311. A handwheel 237 is fixedly installed at one end of the sliding locking pin 235. A threaded hole 238 is opened at the top of the sliding locking pin 235. A threaded button 236 penetrates the top of the rotating drum 232. The bottom end of the threaded button 236 penetrates the sliding locking hole 234 and is threaded into the threaded hole 238.

[0040] Under normal conditions, one end of the sliding latch 235 is inserted into the connecting cylinder 2311, and the side of the sliding latch 235 engages with the groove inside the connecting cylinder 2311. The device is opened and closed by the motor 2310. The bottom end of the threaded button 236 passes through the sliding latch hole 234 and is threaded into the threaded hole 238. When the motor 2310 is damaged and cannot drive, the threaded button 236 is pulled out, and the sliding latch 235 is pulled out by the handwheel 237. This allows for manual opening and closing of the device. Manual opening and closing is a backup method, effectively avoiding serious consequences such as gas leakage and explosion when the electric control cannot be used.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] During operation, firstly, the internal pressure of valve pipe 1 is judged by 6. When the pressure exceeds the set standard, motor 2310 runs and drives connecting cylinder 2311 to rotate. Connecting cylinder 2311 drives rotating cylinder 232 and worm gear 233 to rotate. Worm gear 233 drives worm wheel 227 to rotate, causing sleeve 226 to rotate. Sleeve 226 drives threaded column 225. Threaded column 225 drives lifting rod 221 to descend. When lifting rod 221 descends, limit block 2210 slides inside limit groove 224 to limit the movement of lifting rod 221. Lifting rod 221 drives valve plate 222 and rubber ring 223 to insert into the vertical pipe of valve pipe 1 to isolate the gas.

[0043] When the motor 2310 is damaged and cannot be driven, the threaded button 236 is turned out, and the sliding latch 235 is pulled by the handwheel 237. At this time, one end of the sliding latch 235 is pulled out of the connecting cylinder 2311, thereby realizing the manual opening and closing of the device.
