Description

Technical Field

[0001] The utility model relates to the technical field of gas filling, in particular to a filling device for industrial gases with an interlock cut-off facility. Background Technique

[0002] Industrial gases basically refer to a kind of bottled compressed liquid gas, which is in a gaseous state under normal temperature and pressure. There are many types of gases, mainly used in various industrial manufacturing aspects. In industry, it is often necessary to fill these gases for sale or transportation; and in the process of filling industrial gases, in order to improve the use safety, an interlock cut-off facility is usually used together. The interlock cut-off facility is a safety device used to automatically cut off the fluid pipeline or equipment under specific conditions to prevent accidents from occurring or intensifying. This facility is usually combined with an alarm system. When certain abnormal conditions (such as too high pressure, abnormal temperature, etc.) are detected, it can automatically start the cut-off measure, thereby protecting the safety of the system and the surrounding environment.

[0003] A kind of industrial gas filling equipment (the authorization announcement number is CN218348410U) is disclosed in the patent database, including a workbench, a gas storage tank, an air supply pipe, an increasing pump, a delivery pipe and a weighing mechanism. The workbench is placed horizontally, the gas storage tank is fixedly installed at the top of the workbench, the output end of the gas storage tank is communicated with the input end of the air supply pipe, and the output end of the air supply pipe is communicated with the input end of the increasing pump. Its gas cylinder is placed on the weighing mechanism. When the increasing pump is started, the increasing pump transports the gas in the gas storage tank through the air supply pipe into the increasing pump, and the gas is then transported through the delivery pipe into the retractable filling mechanism. The retractable filling mechanism adjusts to fill gas cylinders at different heights. The weighing mechanism weighs the gas cylinders. When the weight of the gas cylinder reaches a certain standard, the increasing pump is closed, and the gas stops filling the gas cylinder, simplifying the operation process of filling gas cylinders at different heights, improving the convenience of filling gas in gas cylinders, improving the gas filling efficiency, and improving the safety.

[0004] During the use of the above device, after the gas cylinder is filled, it is necessary to manually replace the filled gas cylinder. And the gas cylinders used to hold gases are usually relatively heavy, resulting in a long time for replacing the filled gas cylinders, low efficiency of gas cylinder filling, and poor practicability.

[0024] Working principle of the utility model: During use, place the bottle to be inflated into the fixed seat 11. Under its own gravity, it pushes down the push plate 12, causing the push plate 12 to push the connecting rod 13. The connecting rod 13 drives the connected rack 14 to slide along the limiting rod 15, causing the rack 14 to drive the gear 16 to rotate. The gear 16 cooperates with the first tooth groove to drive the transmission rod 17 to move. The transmission rod 17 drives the connected clamping block 18 to move, thereby clamping the workpiece and limiting and fixing it to prevent shaking during filling, which may affect the filling effect. At the same time, when the push plate 12 moves downward, it pushes the guide rod 19 to drive the stopper 20 and then stretches the spring 21. After that, start the motor 27 to drive the turntable 10 to rotate, moving the bottle to be inflated on it below the filling station. Then, start the telescopic rod 8 to drive the inflation head to move downward for filling. When the filling is completed, start the motor 27 to drive the turntable 10 to rotate, moving the filled bottle to one side, moving the new bottle to be inflated to the station for inflation, and at the same time, the filled bottle can be removed, unloaded, and a new bottle can be installed, improving the filling efficiency and making it more convenient to use. When it is necessary to disassemble and repair the cut-off valve 5, apply force to the support column to drive the toothed ring 23 to rotate. The toothed ring 23 rotates under the guiding and limiting of the limiting ring 24. Thus, the toothed ring 23 cooperates with the second tooth groove to drive the limiting ring 24 to drive the threaded cylinder 25 to rotate, separating it from the bolt, making it convenient to disassemble the cut-off valve 5. During installation, repeat the above operation to connect the threaded cylinder 25 with the bolt, making it convenient to disassemble, install, repair, and maintain the cut-off valve 5, with convenient use and stronger practicability.
