The invention relates to a password lock device of a gas cylinder valve, an unlocking device and an unlocking method of the password lock device. The password lock device of the gas cylinder valve comprises a password lock and the unlocking device matched with the password lock device; the password lock is arranged in an extension section on the side wall of the gas cylinder valve and includes a sliding block and a controlled piece; one of the outer wall of the sliding block and the inner wall of the extension section is provided with a baffle piece, and the other one of the outer wall of thesliding block and the inner wall of the extension section is provided with a passage matched with the baffle piece; the unlocking device is provided a driving component matched with the controlled piece, the driving component is capable of driving the sliding block to rotate about the axial direction of the sliding block through the controlled piece to correspond to the baffle piece and the passage, the sliding block is enabled to move in the axial direction, a valve element is unlocked or locked, and the opening or closing of the gas cylinder valve can be controlled. The password lock deviceof the gas cylinder valve enables the filling of a gas cylinder to be effectively controlled through the password setting, the illegal filling and fault filling behaviors are avoided, and safety is improved.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a combination lock device, an unlocker and an unlocking method for a gas cylinder valve. The gas cylinders refer to the range of gas cylinders specified in TSG R0006-2014 "Gas Cylinder Safety Technical Supervision Regulations". Background technique [0002] In recent years, liquefied gas, as a new type of fuel, has quickly entered thousands of households due to its convenience, speed and cleanliness. However, due to the potential safety hazards of liquefied gas cylinders filled with liquefied gas, it will endanger the personal property security. [0003] In order to ensure the safety of users' lives and properties, the filling of liquefied gas cylinders adopts a fixed-point filling method, which can establish a complete management file for liquefied gas cylinders, so as to prevent the use of uninspected and scrapped liquefied gas cylinders. However, due to the chaotic management...
