Description

Technical Field

[0001] The utility model relates to the technical field of gas tank safety, in particular to an intelligent direct switch gas tank valve device. Background Art

[0002] Gas cylinders are widely used in all aspects of life and production. There are safety hazards of leakage, fire and even explosion during the use of gas cylinders. It can be seen that it is very necessary to develop an intelligent electric angle valve alarm cut-off device.

[0003] The existing gas pipeline valve closing device for gas leakage does not directly close the valve on the gas tank, and does not close the gas tank valve from the source. If gas leakage occurs at the gas tank interface, the safety hazard of leakage and explosion cannot be avoided. If a fire occurs due to other reasons and the gas tank is placed next to the flame, if the gas tank valve is not closed in time, the risk of gas tank leakage and explosion will increase significantly, and the rescue time for firefighters will be greatly shortened. If the gas tank leaks and sprays flames due to improper operation, most people may not close the gas tank valve out of fear, which increases the risk of gas tank explosion.

[0004] Therefore, it is necessary to design and transform the intelligent direct switch gas tank valve device. Utility Model Content

If the gas leaks to the gas tank interface, the safety hazard of leakage and explosion cannot be avoided. If a fire occurs due to other reasons and the gas tank is placed next to the flame, if the gas tank valve is not closed in time, the risk of gas tank leakage and explosion will be greatly increased, and the rescue time for firefighters will be greatly shortened. If the gas tank leaks and sprays flames due to improper operation, most people may be afraid and not close the gas tank valve, thus increasing the risk of gas tank explosion.

[0038] As a technical optimization scheme of the utility model, a motor torque monitoring algorithm is designed through the control system, which can accurately tighten the gas valve 2 and prevent the problem of the valve 2 not being able to be closed. The existing technology is to switch the valve 2 by controlling the motor to rotate a fixed number of circles or controlling the motor to rotate for a fixed time. The fixed number of circles method will cause the valve 2 to not be tightened after a long time. The fixed rotation time method will still output 1-2 seconds to control the motor to rotate after tightening, resulting in over-tightening and shortening the life of the gas tank 1 valve 2.

[0039] refer to Figure 6 The detection module 13 includes a smoke detection module 15, a gas detection module 14 and a temperature sensor 16 which are electrically connected to the surface of the control circuit 9 respectively.

[0040] As a technical optimization solution of the utility model, the handle sheath 19 is fixed by adsorbing the strong magnet 21, and the two bends on the bottom plate 5 clamp the valve 2 handle sheath 19 to prevent the bottom plate 5 from rotating.

The control circuit 9 is integrated with a networking module 17. Users can bind the device through the WeChat applet and operate the mobile phone to open and close the gas valve 2. When a gas leak or a large amount of smoke or the temperature exceeds 60°C occurs, the user can be notified by phone, text message, etc.
