Description

Technical Field

[0001] This utility model belongs to the field of gas filling technology, and specifically relates to a gas filling safety tool. Background Technology

[0002] Gas filling is the process of transferring gas from a production or storage facility to a portable or stationary container. During the filling process, the gas is compressed and loaded into the container, usually under high pressure to ensure that the gas has sufficient pressure in the container for subsequent use. Gas filling is used to meet the needs of various gases in industries such as industry, medicine, scientific research, and fire protection. By filling the gas into portable gas cylinders, the gas can be conveniently transported to the place of use, especially in situations where it cannot be directly connected to a gas supply pipeline, and for long-term storage so that it can be used when needed.

[0003] In existing technologies, gas filling is mostly carried out by directly exposing the filling process to the outside air. It lacks safety protection structures and real-time detection and warning functions, which increases safety hazards and cannot effectively ensure the safety and reliability of gas filling. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a gas filling safety tool to solve the problem mentioned in the background art that most gas filling operations are carried out in direct exposure to the outside air, lacking safety protection structures and real-time detection and prompting functions, thereby increasing safety hazards and failing to effectively ensure the safety and reliability of gas filling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas filling safety tool, comprising a protective box, a door on one side of the protective box, a fixed cylinder fixedly connected to one side of the inside of the protective box, an elastic buffer ring fixedly connected to the inner side of the fixed cylinder, a gravity sensor fixedly connected to one side of the inside of the protective box, cylinders symmetrically fixedly connected to the top of the protective box, a moving plate fixedly connected to the output end of the cylinder, a diverter pipe provided on the top of the moving plate, an inflation pipe fixedly connected to the bottom of each diverter pipe, a pressure plate fixedly connected to the outer side of the inflation pipe, and an inflation valve fixedly connected to the top of the protective box.

[0006] Preferably, the door is rotatably connected to the protective box via a hinge, an observation window is provided inside the door, and a handle is fixedly connected to one side of the door.

[0007] Preferably, a control panel is fixedly connected to one side of the protective box, and an alarm is fixedly connected to one corner of the top of the protective box.

[0008] Preferably, an inflation bottle is provided inside the elastic buffer ring, and a control valve is provided at the upper end of the outer side of the inflation bottle.

[0009] Preferably, the diversion pipe is fixedly connected to the movable plate via a fixing block.

[0010] Preferably, a sealing gasket is fixedly connected to the bottom of the pressure plate.

[0011] Preferably, a flow control valve is fixedly connected to the upper end of the outer side of the inflation valve, a pressure relief valve is fixedly connected to one side of the inflation valve, a connecting hose is fixedly connected to the bottom of the inflation valve, and the connecting hose and the diverter pipe are fixedly connected.

[0012] Preferably, the protective box is equipped with an explosion-proof layer inside.

[0013] Compared with the prior art, this utility model provides a gas filling safety tool, which has the following features:

[0014] Beneficial effects:

[0015] 1. This utility model incorporates multiple gas cylinders installed inside a fixed cylinder and an elastic buffer ring. Due to the elasticity of the buffer ring, it can protect and secure gas cylinders of various sizes, thus expanding the applicability of this safety tool. During gas filling, the door is closed, the filling valve is connected to an external filling source, and the cylinder pushes the moving plate downwards, causing the pressure plate to contact the top of the gas cylinder, creating a sealed environment. Then, the filling source is turned on, and gas enters the gas cylinder through the filling valve, connecting hose, diverter pipe, and filling pipe. The protective box provides protection. In the event of an explosion, the explosion-proof layer will absorb the energy generated, limiting the blast radius and protecting the surrounding environment and personnel, thus providing effective safety protection for gas filling operations.

[0016] 2. This utility model uses a gravity sensor to detect the weight of the gas cylinder in real time. If the weight is lower than the preset value, it indicates a gas leak. The signal is transmitted to the control panel, which then activates the alarm to provide an alert, allowing operators to respond to emergencies. During the filling process, the pressure relief valve automatically monitors the pressure and will automatically open to release pressure if necessary. The flow control valve precisely controls the filling speed. The overall structure helps to ensure the safety and reliability of the gas filling operation.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description
